Chalmers invests heavily in the area of health and technology. In the elective course Here, there and everywhere – healthcare integrated in our everyday lives and places, students from different programmes, teachers and industry representatives with different areas of expertise, collaborate. Their task is to find new solutions to the challenges within the global healthcare sector.</b></p>​<span style="background-color:initial">To improve the technical development of the sector, various areas of knowledge within Chalmers can play a key role, such as architecture, organizational development and e-health solutions.</span><div><br /></div> <div>“Chalmers has students who are competent in these three areas, but that doesn’t mean they are automatically good at collaboration. They need to practice interdisciplinary teamwork! For us, that was the starting point when we created this Tracks course” says Patrik Alexandersson who is responsible for the course.</div> <div><br /></div> <div><img src="/SiteCollectionImages/20210101-20210631/SebastanRye_biltilltext.jpg" alt="sebastian rye, student" class="chalmersPosition-FloatLeft" style="margin:5px;width:180px;height:180px" /><br /></div> <div>Chalmers student, Sebastian Rye, participated in the first round of the course <em>Here, there and everywhere – healthcare integrated into our everyday lives and places</em>. He is currently studying his final year of Industrial Engineering and Management and is currently writing his Master thesis where he investigates how the use of artificial intelligence can be used in an efficient way in the healthcare sector.</div> <div><br /></div> <div>“I had actually already chosen all my elective courses, but the Tracks course great combination of healthcare, interdisciplinary collaboration with mixed student groups and the opportunity to make contacts in the industry was a little too difficult to resist. I just had to take that extra course!”.</div> <h3 class="chalmersElement-H3">Current and real challenges</h3> <div>Tracks is a major investment in education and in new learning environments funded by the Chalmers Foundation. Tracks elective courses will complement students' programmes, introduce them to new subject areas and give them the opportunity to practice interdisciplinary teamwork.</div> <div><br /></div> <div>Tracks courses are also linked to the latest research and to industry. In this course, the subject area was presented by representatives from the Högsbo Specialist Hospital and from Sahlgrenska University Hospitals’ digital R&amp;D department. Chalmers Center for Healthcare Improvement (CHI) is also behind the course as well as patients who were involved to give feedback on the students' solutions.</div> <div><br /></div> <div>The intention with Tracks courses is that they should be able to quickly adapt to current needs and challenges in work-life and society. The healthcare-course is a good example. In the spring of 2020, when the new corona virus began to spread around the world, the teachers decided to include a case about pandemic management in the course, which was not planned from the beginning. Students could choose from three different cases to work with together in small groups: Pandemic, “Life Event Cancer” and Virtual Hospital.</div> <div><br /></div> <div>The case called “Life Event Cancer” shed a light on the fact that there are more things than just the patient's disease that needs to be taken care of in the case of a cancer diagnosis. One question that the students discussed was how and with what digital tools the patient and their families can be supported throughout a treatment period.</div> <div><br /></div> <div>Virtual hospital and virtual care in general are current topics in the healthcare sector today. Healthcare can be provided in many ways and doesn’t always have to be linked to a physical hospital building. Åsa Holmgren, project manager at Högsbo Specialist Hospital, believes that more technical solutions are needed, but that they need to be carefully examined – which solutions are the most useful within the healthcare sector? In response to which situations and when can they be applied for the best possible outcomes?</div> <div><br /></div> <div>“By learning more about how different technical solutions can be used, healthcare can be changed and improved. An example could be to develop the patient's ability to self-test at home, which the medical staff can follow up and manage – maybe it can lead to faster regulation of drug dosage. I have to say that the students impressed me with their insights and innovative suggestions in their final presentations!” says Åsa Holmgren.</div> <div><br /></div> <div>Among other things, the students had suggestions for continuous feedback from a number of health parameters in patients staying at home. This is something that may create a preventive effect. Patients with better knowledge of their own health would also contribute to a more accurate decision-making by the caregiver. An increased use of Machine learning was also proposed, in order to, for example, identify early risk parameters for potential development of cancer.</div> <div><br /></div> <div>In their final presentations the students came up with ideas regarding different health parameters that may be possible for the patients to control by themselves, at home. Something that could have a preventive effect and provide the patients with better knowledge of their own health status and contribute to an improved decision-making-process for the healthcare provider. Another suggestion from the students was more frequent use of Machine Learning. This could be a tool to identify early risk parameters for potential development of cancer.</div> <h3 class="chalmersElement-H3">Aim to increase students’ interest in the healthcare sector</h3> <div>During the first round of the course Here, there and everywhere – healthcare integrated in our everyday life and places, Chalmers students from eight different educational programmes participated and for the next course, planned this autumn, Patrik Alexandersson aims for even more.</div> <div><br /></div> <div>“We hope that our course can lead to increased knowledge of, and interest in healthcare among architecture and engineering students. By participating in the course, students gain a very good insight into the sector's challenges and its logic, which is enormously positive, both for themselves, Chalmers and for society in general.”</div> <div><br /></div> <div>Sebastian Rye was already interested in the subject before the start of the course, and he thinks that the opportunity to choose a course based on his own interest was very rewarding.</div> <div><br /></div> <div>“The teachers were incredibly committed and experienced in the area and guided us throughout the course, but at the same time it was a lot of project-oriented teamwork and a lot of self-studies. I really thought that the course complemented my other studies well, because in Tracks courses you get to practically apply the things you have learned to a subject you are interested in. This means that the knowledge you have gained from your programme actually gets enhanced!”</div> <div><br /></div> <div><a href="/en/news/Pages/chalmers.se/sv/nyheter/Sidor/Studenter-med-och-skapar-framtidens-vard.aspx" title="course poster"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icpdf.png" alt="" />Read more about the <span style="background-color:initial">course</span>​</a></div> <em> </em><div><a href="https://student.portal.chalmers.se/en/chalmersstudies/tracks/Pages/current-courses-within-tracks.aspx" title="chalmers study portal"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /><span style="background-color:initial">Read more about the c</span><span style="background-color:initial">urrent courses within Tracks</span></a></div> <div><em style="background-color:initial"></em></div> <div></div> <div><br /></div> <div><br /></div> <div><strong>Text:</strong> Julia Jansson</div> <div><strong>Photo:</strong> Västfastigheter, Sjukhusen i väster och Högsbo specialistsjukhus</div> ​Fri, 09 Apr 2021 02:00:00 +0200https://www.chalmers.se/en/departments/bio/news/Pages/Materials-science-and-biotech-explore-new-territory.aspxhttps://www.chalmers.se/en/departments/bio/news/Pages/Materials-science-and-biotech-explore-new-territory.aspxMaterials science and biotech explore new territory<p><b>​Researchers in Materials Science and Industrial Biotechnology at Chalmers University of Technology will combine forces to produce sustainable light-weight materials of the future. The project, led by Chalmers, has been awarded the prestigious EU-grant FET Open. ​</b></p><p class="chalmersElement-P">​<span>The aim of the FET Open-project is to develop lightweight materials from wood-based components, involving metabolically engineered microorganisms in the process. </span></p> <p class="chalmersElement-P"><span>There is an urgent need to reduce causes of climate change, microplastic pollution and raw material shortages, and this may be achieved by replacing fossil-based resources with renewable ones.

Enhancing the performance of modern supercomputers, whilst minimizing their energy losses, represent two contrasting but major needs that the information technology industry will have to address in the future.</span><div><br /></div> <div>As a participant of the international research network SuperGate (Gate Tuneable Superconducting Quantum Electronics), researchers from Chalmers are now taking part in a EU-funded project to create a new basis for the super-computers of tomorrow: to develop a bridging technology that combines superconductor technology with semiconductor technology, using an approach that was considered physically impossible until just a few years ago. The two technology systems have up till then been considered incompatible in the sense that semiconductors are controlled by voltage and operate at room temperature, while superconductors, on the other hand, are based on current and operate at temperatures of around minus 270 degree Celsius, near absolute zero. Combining the more powerful and more energy-efficient superconductor technology with existing semiconductor technology is of great interest in high-performance computer development. </div> <div><img src="/SiteCollectionImages/20210101-20210631/SimoneGasparinetti_350x305px%20NY.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px;width:180px;height:157px" /><br />– This project will shed some light on a physical effect that we do not fully understand, and, at the same, it provides a clear pathway to utilization, says Simone Gasparinetti, project leader of the research team from the department of Microtechnology and Nanoscience at Chalmers University of Technology. </div> <h2 class="chalmersElement-H2">A path-breaking discovery</h2> <div>The SuperGate research project is coordinated by the University of Konstanz and funded with around 3 million euros through an FET Open Grant (FET: Future and Emerging Technologies) of the European Union. The idea behind the project stems from a path-breaking discovery made by physicists at the Consiglio Nazionale delle Ricerche (CNR) in Pisa (Italy). They managed to demonstrate that superconductivity in a weak link can be controlled by applying voltages to electrostatic gates, in a similar way as semiconducting transistors are controlled by the field effect. This discovery has the potential to revolutionize the world of supercomputing, leading to a technology that would combine the advantages offered by semiconductors and superconductors. A discovery that didn’t go unnoticed by the researchers at the department of Microtechnology and Nanoscience at Chalmers. </div> <div><br /></div> <div><span style="background-color:initial">–</span> Back a few years ago, after seeing the first results of Pisa group, I got curious about them and started to run some experiments in our lab.

In addition, the control has been demonstrated only at low frequencies (dc and audio band), while the prospected applications require switching at much higher frequencies (GHz and above). The main task for the Chalmers research team is to investigate the origin of the effect and test the response at high frequencies. In order to optimize speed and performance the Chalmers team will try out different materials and geometries and finally develop a range of logic circuits and combine them with conventional semiconductor technology. </div> <div><br /></div> <div><span style="background-color:initial">–</span> Our task will be to investigate the gated superconducting weak links at high frequencies.

But the photovoltaics panels mounted on Swedish rooftops and in solar parks are almost exclusively imported. New research from Chalmers University of Technology shows how Sweden could have had a domestic industry for production of photovoltaics. The lack of a clear national strategy is one of the reasons why it did not happen.</b></p><div>​A new article in the scientific journal Renewable and Sustainable Energy Reviews describes the growth of the solar energy industry in Sweden. The authors of the article are the Chalmers’ researchers Johnn Andersson, Hans Hellsmark and Björn Sandén at the Department of Technology Management and Economics, Division of Environmental Systems Analysis.</div> <div> </div> <div>With the expansion of solar energy, a successful installation industry has emerged in Sweden. The installed photovoltaics (PV) products, however, are developed and manufactured abroad, especially in China.</div> <div> </div> <div>“There is no reason why we could not have created a photovoltaics industry in Europe and Sweden as well. Initially, the idea was rather the opposite: ‘we can build a Swedish photovoltaics industry, but we will really not make use of solar energy here’. At the time, it was not thought that solar panels would be effective up here. Instead it was the industrial development that failed, because of the lack of right efforts”, says Professor Björn Sandén.</div> <div><br /></div> <div><h2 class="chalmersElement-H2">No strategic support</h2></div> <div>There are many explanations why this happened. In the article, the authors discuss, among other things, the absence of strategic political support measures.</div> <div> </div> <div>“Political actors did not have a holistic perspective on development and therefore failed to create a cohesive innovation system, which can create conditions for domestic development in all parts of the photovoltaics value chain: from manufacturing to installation”, explains Johnn Andersson, whose doctoral thesis was the basis for a large part of the research.</div> <div> </div> <div>“If we had invested differently, we might have been able to participate in the industrialization process. It is not certain in any way, and it is not easy for a small country to manage something like this. But of course we can industrialize things here – If there is a will. A recent example is battery manufacturing, which is now gaining ground in Sweden as well. But when it comes to photovoltaics, there are few trying to see the whole picture and how to invest in the area strategically”, says Björn Sandén.</div> <div> </div> <div>The state has several important roles to play. It has access to instruments that no other actors have, can set rules for the market, create infrastructure, shape expectations and develop networks. Based on these conditions, it is up to entrepreneurs and other actors to act.</div> <div> </div> <div><em>Is it a lost race, is it too late for Sweden to catch up now?</em></div> <div> “We are still only at the beginning of a development. There are lots of untapped opportunities. Today, solar energy is only a few permille or percent of what it will be in the end, in terms of size. There is still a huge growth in all possible directions. As an example, we point to the thin films that can have special application areas. When you connect it with building materials or applications in vehicles or whatever it may be, many new opportunities will arise”, says Björn Sandén.</div> <div> </div> <div><em>What would be the point of manufacturing in Sweden, then? Apart from obvious benefits for Swedish economy and Swedish jobs, and perhaps shorter transports.</em> </div> <div>“More and more companies are thinking about the entire life cycle and the entire supply chain: What are the ethical and environmental consequences that occur in this chain. As for photovoltaics produced in China, there is a discussion about the use of coal energy to produce them, and what about the working conditions, and so on. When you start to think about the entire production chain and the consequences of it, it can affect where you want to locate the production. This can be an argument for placing it in Sweden, for example.”</div> <div> </div> <div>Björn Sandén believes there is a general benefit to think about climate change and industrial policy in unison:</div> <div> </div> <div>“You can gain a lot from thinking about these two issues at the same time, so you can take advantage of the industrial opportunities that come with the global energy transition. Especially for a country with advanced competencies like Sweden.”</div> <div> </div> <div><img src="/sv/institutioner/tme/nyheter/PublishingImages/solcellsforskarna_750x340.jpg" alt="" style="margin:5px" /><br /><em>The researchers behind the study: </em><span><em>Johnn Andersson, Hans Hellsmark and Björn Sandén</em><span></span></span><br /> </div> <h2 class="chalmersElement-H2">The history of the Swedish photovoltaics industry</h2> <div>The development can be divided in different phases. In the 1980s and 1990s, there was an advance of knowledge in thin film technology. It was discussed how this could be exploited in Sweden and attempts were also made to commercialize the technology. The foremost example is the company Solibro. They were bought by a German company, which in turn was taken over by a Chinese company. There was a lack of interest from the Swedish industry, one reason being the absence of earlier similar products.  There were also other tracks with different types of technology that led to smaller companies, but nothing of considerable size.</div> <div> </div> <div>During the 1990s, and detached from the previously mentioned development, a modular assembly industry started to grow in Sweden. Photovoltaic cells were imported, assembled, and then the finished modules were exported. This became a large industry for a while, before it was completely wiped out when prices fell sharply as international competition intensified and large production plants were built in China.</div> <div> </div> <div>As photovoltaics became cheaper and with the help of national subsidy programs the use of solar energy systems started to grow. Today, there is no production of photovoltaics modules left in the country. There are some smaller initiatives, such as university spin-offs and other small businesses in the area. But more than anything, there is a growing installation industry.</div> <div><br /></div> <div><em>Text: Daniel Karlsson</em> <br /></div> <div> </div> <h3 class="chalmersElement-H3">The scientific article</h3> <div><a href="https://www.sciencedirect.com/science/article/pii/S136403212100188X" target="_blank">&quot;Photovoltaics in Sweden - Success or failure?&quot;</a> by Johnn Andersson, Hans Hellsmark, Björn Sandén</div> <div>Renewable and Sustainable Energy Reviews, Volume 143, June 2021, 110894</div> <div> </div> <h3 class="chalmersElement-H3">How the research was carried out    </h3> <div>The research in the article is based on a socio-technical systems perspective on technological innovation.

In a new study, researchers from Chalmers University of Technology, Sweden, and the University of Louvain, Belgium, evaluated over a thousand policy proposals for how the EU could reduce this impact, to assess which would have the largest potential to reduce deforestation – while also being politically feasible.</b></p><div><span style="background-color:initial">“Unsurprisingly, there is weaker support for tougher regulations, such as import restrictions on certain goods. But our study shows that there is broad support in general, including for certain policies that have real potential to reduce imported deforestation,” says Martin Persson, Associate Professor of Physical Resource Theory at Chalmers University of Technology.​</span></div> <div><br /></div> <div><span style="background-color:initial"></span><a href="/en/departments/see/news/Pages/EU-consumption-plays-major-role-in-tropical-deforestation.aspx">Previous research from Chalmers University of Technology has already shown the EU's great impact in this area​</a>. More than half of tropical deforestation is linked to production of food and animal feed, such as palm oil, soybeans, wood products, cocoa and coffee – goods which the EU imports in vast quantities. The question is, what can the EU do to reduce its contribution to deforestation?</div> <div> </div> <div><br /></div> <div> </div> <div>“This issue is particularly interesting now, as this year the EU is planning to present legislative proposals for reducing deforestation caused by European consumption. The question has been discussed by the EU since 2008, but now something political is actually happening,” says Simon Bager, a doctoral student at the Université Catholique de Louvain, Belgium, and lead author of the study.</div> <div> </div> <div><br /></div> <div> </div> <div>The authors of the article mapped 1141 different proposals, originating from open consultations and workshops, where the EU has collected ideas from companies, interest groups and think tanks. The researchers also compiled proposals from a large number of research reports, policy briefs and other publications, where different stakeholders have put forward various policy proposals. After grouping together similar proposals, they arrived at 86 unique suggestions.</div> <div> </div> <div><br /></div> <div> </div> <h2 class="chalmersElement-H2">Two sugg​estions stand out</h2> <div> </div> <div><span style="background-color:initial">Finding proposals for measures that would have the desired effect but are also possible to implement in practice, and enjoy the necessary political support, is no easy task. But after their extensive survey, the researchers identify two policy options in particular which show promise. The first is to make importers of produce responsible for any deforestation in their supply chains, by requiring them to carry out the requisite due diligence.</span><br /></div> <div> </div> <div><span style="background-color:initial"><br /></span></div> <div> </div> <div>“If the importing companies’ suppliers have products that contribute to deforestation, the company may be held responsible for this. We consider such a system to be credible and possible to implement both politically and practically – there are already examples from France and England where similar systems have been implemented or are in the process thereof,” says Simon Bager.</div> <div> </div> <div>“Due diligence is also the measure which is most common in our survey, put forward by many different types of actors, and there is broad support for this proposal. However, it is important to emphasise that for such a system to have an impact on deforestation, it must be carefully designed, including which companies are affected by the requirements, and which sanctions and liability options exist.”</div> <div> </div> <div><br /></div> <div> </div> <div>The other possibility is to support multi-stakeholder forums, where companies, civil society organisations, and politicians come together to agree on possible measures for ridding a supply-chain, commodity, or area, of deforestation. There are positive examples here too, the most notable being the Amazon Soy Moratorium from 2006, when actors including Greenpeace and the World Wide Fund for Nature gathered with soy producers and exporters and agreed to end soy exports from deforested areas in the Amazon rainforest.</div> <div> </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/EU-Mercosur-martin-Persson.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“Examples suc<span style="background-color:initial">h as these demonstrate the effect that multi-stakeholder forums can have. And in our opinion, it is a measure that is easier to get acceptance for, because it is an opportunity for the affected parties to be directly involved in helping design the measures themselves,” says Martin Persson.</span></div> <div> </div> <div><br /></div> <div> </div> <div>Such discussions can also be adapted to the relevant areas or regions, increasing the likelihood of local support for the initiatives.</div> <div> </div> <h2 class="chalmersElement-H2">A delicate ​​balance</h2> <div> </div> <div>The researchers also investigated how to deal with the trade-off between policy impacts and feasibility. An important part of this is combining different complementary measures. Trade regulations on their own, for example, risk hitting poorer producing countries harder, and should therefore be combined with targeted aid to help introduce more sustainable production methods, increasing yields without having to resort to deforestation. This would also reduce the risk of goods that are produced on deforested land simply being sold in markets other than the EU.</div> <div><br /></div> <div> </div> <div>“If the EU now focuses on its contribution to deforestation, the effect may be that what is produced on newly deforested land is sold to other countries, while the EU gets the ‘good’ products. Therefore, our assessment is that the EU should ensure that the measures introduced are combined with those which contribute to an overall transition to sustainable land use in producing countries,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>In conclusion, the researchers summarise three essential principles needed for new measures, if the EU is serious about reducing its impact on tropical deforestation.</div> <div><br /></div> <div> </div> <div>“First, enact measures that actually are able to bring about change. Second, use a range of measures, combining different tools and instruments to contribute to reduced deforestation. Finally, ensure the direct involvement of supply chain actors within particularly important regions, expanding and broadening the measures over time,” concludes Simon Bager.</div> <div><br /></div> <div> </div> <div>The authors hope that the research and identified policy options can serve as inspiration for policy makers, NGOs, industries, and other stakeholders working to address the EU's deforestation footprint. With at least 86 different unique alternatives, there is a wide range of opportunities to focus on the problem – very few of these are political 'non-starters' or proposals which would have no effect on the issue.</div> <div> </div> <div>The full study, Eighty-six EU policy options for reducing imported deforestation is available open-access in the journal One Earth:</div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">For more information, contact:​</h3> <div> </div> <div>Martin Persson, Associate Professor, Physical Resource Theory at Chalmers University of Technology, martin.persson@chalmers.se, +46 31 772 2148</div> <div> </div> <div><br /></div> <div> </div> <div>Simon Bager, Ph.D. candidate UCLouvain and MSCA fellow COUPLED, simon.bager@uclouvain.be, +45 2721 7414</div> <div> </div> <div><br /></div> <div> </div> <div><h3 class="chalmersElement-H3"><span>More detailed information regarding how the study was conducted:</span></h3></div> <div> </div> <div>To investigate the potential impact and political feasibility of the 1141 proposals, the researchers first categorised them based on who submitted the proposal, who the policy would affect, and what type of policy is proposed. Since many of the proposals were essentially the same or similar, they were then summarised, resulting in 86 unique suggestions. The majority are based on weaker measures, such as making more information and types of support available to producers, rather than statutory restrictions and regulations on imports and exports. The researchers interpret this as meaning that there is greater support for softer proposals. However, the researchers themselves consider these proposals to be less effective.</div> <div><br /></div> <div> </div> <div>“One example is eco-labelling, where the purpose is to influence consumers to stop buying products that contribute to deforestation. The intent is good, but previous research does not support the argument that this changes consumer behaviour to such a level that production itself is affected. But if import restrictions are instead introduced on goods that are linked to deforestation, it is already known that this has direct effects,” says Martin Persson.</div> <div><br /></div> <div> </div> <div>After evaluating the likely effects, the next step was to see which proposals could actually receive political support, and how complex and costly the formulation and implementation was likely to be. For this evaluation, methodological innovations were required.</div> <div><br /></div> <div> </div> <div>“After categorising the 1141 proposals, we could see how many stakeholders, and of which kind, proposed a certain type of measure. If the same option was proposed by many actors, of different kinds – environmental organisations, companies, and authorities – we interpreted that as strong, broad support for the proposal,” explains Martin Persson.</div> <div><br /></div> <div> </div> <div>The last two steps in the assessment of the measures were then about how complicated and expensive it would be to realise the proposals.</div> <div><br /></div> <div> </div> <div>“For example, commissioning a research institute to investigate, at a detailed level, what drives deforestation – that would be quite easy. But a new tax or punitive duty at EU-wide level would be very difficult and costly to successfully implement. There are some measures, which the EU can take alone, while others require cooperation with the individual member states or third countries. And there we simply rated the institutional difficulty for implementation of each proposal,” says Simon Bager.</div> <div><br /></div> <div> </div> <div>The last aspect for assessing the political feasibility was looking at the economic impact of the proposal.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“If you influence a large impo</span><span style="background-color:initial">rt flow, that will result in major economic consequences.

But the road to personalized recommendations is long and winding. It passes through the gut, where bacteria make us react differently to the food we eat.</b></p>​<span style="background-color:initial">Researchers are working hard, attempting to come up with personalized or group-based dietary advice. It’s not easy. Much depends on the gut microbiota that is unique to us all.<br /><br /></span><div>One example is dietary fiber, which is an established component of a healthy diet. In a research study that attracted attention last year, Chalmers’ researchers show that whole grains from rye lowered cholesterol levels more than whole grain wheat, but that this effect was dependent of individual’s gut microbiota composition. The study clearly showed that the dietary advice is not equally effective for everyone – but that there is a great potential to increase the health benefits by matching the foods with gut microbiota of the individual.</div> <h2 class="chalmersElement-H2">Hot research area</h2> <div>According to Rikard Landberg, Professor of Food and Nutrition science at Chalmers and one of the speakers at the two-day event Engineering Health in April, research relating the importance of the gut bacteria to diet, dietary advice and health is hot right now.<img src="/SiteCollectionImages/Areas%20of%20Advance/Health/Udda%20format/Rikard_Landberg_300.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /></div> <div>“How and when should we take the gut microbiome into account? How do we design a diet that is optimal for the individual? We are yet quite far from individual dietary advice. There is a lot more we need to know first”, he says.<br /><br /></div> <div>At the same time, there are already commercial apps where you can try to identify your ideal diet. But these tests are often not to be trusted, says Rikard Landberg. They are based on nothing more than existing knowledge about general effects of lifestyle and diet, and the connections between these and the gut microbiota. But already in five to ten years, the situation may be completely different:<br /><br /></div> <div>“By then, I believe we will have the opportunity to identify groups of individuals who, for example, benefit from a certain diet”, says Rikard Landberg and explains:</div> <div>“We should be able to identify the profile of a certain group, using gut microbiome and metabolites – molecules formed by bacteria. Then, we can also measure the body’s response to a certain diet through a blood sample. Based on such data, we can determine whether you belong to a particular profile that would benefit from, for example, eating vegetarian food or a certain type of dietary fiber. And knowing which diet is ideal for your group will of course be helpful if you have reason to review your diet, for example if you’re at increased risk of cardiovascular disease.”</div> <h2 class="chalmersElement-H2">Food and gut experts working together</h2> <div>Rikard Landberg collaborates with Fredrik Bäckhed, Professor at the Department of Molecular and Clinical Medicine at the University of Gothenburg. Fredrik Bäckhed is an expert on gut microbiome and its role in health and disease. Among other things, he is trying to optimize probiotic bacterial strains that can improve the health of our gut, and reduce risk of developing diseases. A permanent change in the intestinal microbiome is difficult to achieve, but vary between different parts of the bacterial flora.</div> <div>“This autumn, we will start a study start where we take a closer look at diets that are composed to promote a healthy intestinal bacterial flora. The diet is designed based on a systematic literature review, where we have reviewed 8,000 scientific articles. We want to investigate whether it is possible, with an optimal diet based on “ordinary food”, to influence intestinal bacteria linked to an increased risk of cardiovascular disease. Strangely enough, this has not been done in any previous scientific study”, says Rikard Landberg.</div> <h2 class="chalmersElement-H2">New and climate friendly guidelines</h2> <div>A revision of Nordic Nutrition Recommendations and the Swedish dietary guidelines is currently underway. Around 100 experts review, and evaluate, research results. Among other things, they look at health impact of different nutrients and foods. The dietary advice is also put in a Nordic context, to take into account which nutrients we, in the Nordic countries, may need to boost – such as vitamin D, which we could lack in our sun-depraved countries – based on the type of food we normally eat. In addition, the dietary advice is climate-adapted; the guidelines should not only focus on what’s healthy, but also what is sustainable from a climate perspective.<br /><br /></div> <div>But while waiting for updated dietary advice, and research on gut microbiota: What can we really say about what to eat in order to stay healthy? One problem is that many researchers – as well as the media – try to give advice based on individual studies, says Rikard Landberg, as there is a desire to go directly from research results to recommendations.</div> <div>“Unfortunately, this might give people the perception that advices change all the time. Results from different studies often show different results, for varied reasons.”</div> <h2 class="chalmersElement-H2">Vegetarian diet possibly healthier</h2> <div>Still, if he would dare to give any advice, in addition to the official dietary guidelines, Rikard Landberg gives one that is aligned with a recent study performed together with Örebro University and Fredrik Bäckhed:<br /><br /></div> <div>“I am quite convinced that a diet with more vegetarian food, and less meat, is better for most of us. But this will vary between individuals, and moreover, we must not forget the risks associated with such a diet for certain groups. Many women, for example, have an iron deficiency. For them, a vegetarian diet might lead to they getting too low intake of available iron – and that will not be healthy”, he says.<br /></div> <div>“Then, of course, the usual advice applies; for example, not eating too much, and avoiding sugar-sweetened beverages. People also tend to think that physical activity plays a large part in keeping a healthy weight, but diet is the most important thing for those who need to watch the kilos. But with that said, we need to be active in order to feel good and prevent illness. Furthermore, we should not forget that diet is much more than health! For example, we do not eat chocolate to be healthy, but because it tastes good. That’s also allowed!”<br /><br /></div> <div><strong>FACTS: Want to know more about diet and intestinal flora?</strong></div> <div>Watch Rikard Landberg’s and Fredrik Bäckhed’s lecture “Diet meets the gut microbiome - implications for cardiometabolic disease” at Engineering Health on April 14 at 11.00.

This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the galaxy, located 55 million light-years away, is able to launch energetic jets from its core.</span><div><br /></div> <div>“We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy,” says Monika Mościbrodzka, Coordinator of the EHT Polarimetry Working Group and Assistant Professor at Radboud University in the Netherlands.</div> <div><br /></div> <div>On 10 April 2019, scientists released the first ever image of a black hole, revealing a bright ring-like structure with a dark central region — the black hole’s shadow. Since then, the EHT collaboration has delved deeper into the data on the supermassive object at the heart of the M87 galaxy collected in 2017. They have discovered that a significant fraction of the light around the M87 black hole is polarised.</div> <div><br /></div> <div>“This work is a major milestone: the polarisation of light carries information that allows us to better understand the physics behind the image we saw in April 2019, which was not possible before,” explains Iván Martí-Vidal, also Coordinator of the EHT Polarimetry Working Group and GenT Distinguished Researcher at the University of Valencia, Spain. He adds that “unveiling this new polarised-light image required years of work due to the complex techniques involved in obtaining and analysing the data.”</div> <div><br /></div> <div>Light becomes polarised when it goes through certain filters, like the lenses of polarised sunglasses, or when it is emitted in hot regions of space where magnetic fields are present. In the same way that polarised sunglasses help us see better by reducing reflections and glare from bright surfaces, astronomers can sharpen their view of the region around the black hole by looking at how the light originating from it is polarised. Specifically, polarisation allows astronomers to map the magnetic field lines present at the inner edge of the black hole. </div> <div><br /></div> <div>“The newly published polarised images are key to understanding how the magnetic field allows the black hole to 'eat' matter and launch powerful jets,” says EHT collaboration member Andrew Chael, a NASA Hubble Fellow at the Princeton Center for Theoretical Science and the Princeton Gravity Initiative in the US.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105b_72dpi_340x227.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div>The bright jets of energy and matter that emerge from M87’s core and extend at least 5000 light-years from its centre are one of the galaxy’s most mysterious and energetic features. Most matter lying close to the edge of a black hole falls in. However, some of the surrounding particles escape moments before capture and are blown far out into space in the form of jets. </div> <div><br /></div> <div><span style="background-color:initial">Astronomers have relied on different models of how matter behaves near the black hole to better understand this process. But they still don’t know exactly how jets larger than the galaxy are launched from its central region, which is comparable in size to the Solar System, nor how exactly matter falls into the black hole. With the new EHT image of the black hole and its shadow in polarised light, astronomers managed for the first time to look into the region just outside the black hole where this interplay between matter flowing in and being ejected out is happening. </span><br /></div> <div><br /></div> <div>The observations provide new information about the structure of the magnetic fields just outside the black hole. The team found that only theoretical models featuring strongly magnetised gas can explain what they are seeing at the event horizon. </div> <div><br /></div> <div>“The observations suggest that the magnetic fields at the black hole’s edge are strong enough to push back on the hot gas and help it resist gravity’s pull. Only the gas that slips through the field can spiral inwards to the event horizon,” explains Jason Dexter, Assistant Professor at the University of Colorado Boulder, US, and Coordinator of the EHT Theory Working Group. </div> <div><br /></div> <div>To observe the heart of the M87 galaxy, the collaboration linked eight telescopes around the world – including the ALMA (Atacama Large Millimeter/submillimeter Array) and APEX (Atacama Pathfinder EXperiment) in northern Chile – to create a virtual Earth-sized telescope, the EHT. The impressive resolution obtained with the EHT is equivalent to that needed to measure the length of a credit card on the surface of the Moon.</div> <div><br /></div> <div>“With ALMA and APEX, which through their southern location enhance the image quality by adding geographical spread to the EHT network, European scientists were able to play a central role in the research,” says Ciska Kemper, European ALMA Programme Scientist at ESO. “With its 66 antennas, ALMA dominates the overall signal collection in polarised light, while APEX has been essential for the calibration of the image.”</div> <div><img src="/SiteCollectionImages/Centrum/Onsala%20rymdobservatorium/340x/eso2105d_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></div> <div><br /></div> <div>&quot;ALMA data were also crucial to calibrate, image and interpret the EHT observations, providing tight constraints on the theoretical models that explain how matter behaves near the black hole event horizon,&quot; adds Ciriaco Goddi, a scientist at Radboud University and Leiden Observatory, the Netherlands, who led an accompanying study that relied only on ALMA observations.</div> <div><br /></div> <div>The EHT setup allowed the team to directly observe the black hole shadow and the ring of light around it, with the new polarised-light image clearly showing that the ring is magnetised.

This continues to the present day, with physics theories of everything, for example string theories, that will describe all known matter and all the forces of nature in one coherent theory. Modular forms play a vital role in the mathematics of string theories, and are also the basis of my planned project.</div> <div><br /></div> <div>Modular forms are mathematical functions that fulfill particular symmetry conditions. Since their discovery, two hundred years ago, they have been vitally important to the development of number theory and other branches of mathematics. There are now many different modular forms and their generalizations. Finding a new class of modular forms is part of the planned project.</div> <div><br /></div> <div>Modular forms also aid the understanding of many phenomena that involve geometric objects, including the small strings that are the foundation of string theory. When these strings collide, they can merge and form new strings. The probability of this is described by string amplitudes, which have shown to fit surprisingly well into an arithmetical framework that is closely related to motivic periods. One objective in this project is to use contributions from string theory in building a broader theory, one that will describe the connection between different motivic periods in families of geometric objects.</div> <div><br /></div> <h2 class="chalmersElement-H2">Degenerate elliptic operators with broad applications </h2> <h3 class="chalmersElement-H3">Professor Andreas Rosén <br /></h3> <div><a href="/en/staff/Pages/andreas-rosen.aspx">Contact</a><br /></div> <div><img class="chalmersPosition-FloatRight" alt="Portrait Andreas Rosén" src="/SiteCollectionImages/Institutioner/MV/Nyheter/KAW%202021/ARosen_180.gif" style="margin:5px" />Harmonic analysis is a branch of mathematics developed in the early nineteenth century, by French mathematician Joseph Fourier as part of his study of heat conduction. To arrive at a solution, he expressed general functions as infinite series of harmonic oscillations, the Fourier series. The planned project focuses on the development of harmonic analysis techniques, which will be used to study materials where the ability to conduct heat varies much in different directions.<br /></div> <div><br /></div> <div>Alongside the Fourier series, there are now many other ways of developing functions as infinite series of a set of basic functions. Wavelets, for example, revolutionized harmonic analysis when they were introduced in the 1980s. The impetus behind their development largely came from their applications – wavelets are now widely used to compress, store and recreate data in electronic engineering, image processing and signal processing.</div> <div><br /></div> <div>There was a new breakthrough in the early twenty-first century, when harmonic analysis was further developed in close relation to, but beyond, wavelets. Andreas Rosén is an expert in these new methods and has applied them to elliptic partial differential equations. The planned study examines equations in which thermal conductivity is permitted to be infinite or zero at some points, and where knowledge is still incomplete. How much can the equation coefficients vary before the theory falls apart? And what happens in cases where thermal conductivity is both infinite and zero at the same point, but in different directions there?</div> <div><br /></div> <h2 class="chalmersElement-H2">Hunting for broken symmetries</h2> <h3 class="chalmersElement-H3">Professor Genkai Zhang</h3> <div><a href="/en/staff/Pages/genkai.aspx">Contact</a><br /></div> <div><img class="chalmersPosition-FloatRight" alt="Portrait Genkai Zhang" src="/SiteCollectionImages/Institutioner/MV/Nyheter/KAW%202021/GZhang_180.gif" style="margin:5px" />The planned project focuses on representation theory, which is a study of abstract algebraic and geometric structures by representing them by simpler, more familiar linear structures in analytic setup. The ideas and methods are not only used in mathematics, but also in other areas such as theoretical physics. Among other things, representation theory is very instrumental in the Standard Model of particle physics.</div> <div><br /></div> <div>Here, the key concept is symmetry. In our everyday lives, we usually think about symmetry as a mirror image, but there are many other symmetries that are less obvious and yet very vital to the advancement of mathematics. One can think of the situation when two children are playing at seesaw: The two kinds of diagonal and up-down symmetries can be better unified in a bigger symmetry group, whereas the symmetry is broken if we consider only one of them. The subject of this project comprises the rules for symmetry breaking (called branching rules by mathematicians) in representation theory.</div> <div><br /></div> <div>Symmetries can be hard to discover. One way of finding them is to study their effects, i.e. their representations on spaces of states that are manifestations of symmetries. Such a study can be more manageable if the representation is restricted to a smaller group of symmetries; the rules for these restrictions are the branching rules. Within the project, researchers will look for and study branching rules for certain restricted representations using methods from analysis and geometry.</div> <h2 class="chalmersElement-H2">Funding for international postdoctoral position</h2> <div>In addition, Antonio Trusiani and Milo Viviani, who both graduated with PhDs from Mathematical Sciences in 2020, have been awarded grants for postdoctoral positions at the Institut de Mathématiques de Toulouse, France, and the Scuola Normale Superiore, Pisa, Italy, respectively.</div> <h3 class="chalmersElement-H3">Read more about their projects at Knut and Alice Wallenberg Foundation</h3></div> <div><a href="https://kaw.wallenberg.org/en/antonio-trusiani">Antonio Trusiani</a></div> <div><a href="https://kaw.wallenberg.org/en/milo-viviani">Milo Viviani</a><br /></div>Wed, 24 Mar 2021 10:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/Novel-thermometer-can-accelerate-the-development-of-quantum-computers.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/Novel-thermometer-can-accelerate-the-development-of-quantum-computers.aspxNovel thermometer can accelerate quantum computer development<p><b>Researchers at Chalmers University of Technology, Gothenburg, Sweden, have developed a novel type of thermometer that can simply and quickly measure temperatures during quantum calculations with extremely high accuracy. The breakthrough provides a benchmarking tool for quantum computing of great value – and opens up for experiments in the exciting field of quantum thermodynamics.​​​</b></p><div><span style="background-color:initial">A key component in quantum computers are coaxial cables and waveguides – structures which guide waveforms, and act as the vital connection between the quantum processor, and the classical electronics which control it.

The waveguide also attenuates and filters the pulses, enabling the extremely sensitive quantum computer to work with stable quantum states.  </span><br /></div> <div><br /></div> <div>In order to have maximum control over this mechanism, the researchers need to be sure that these waveguides are not carrying noise due to thermal motion of electrons on top of the pulses that they send.

If we succeed in lowering the temperature at the end where the waveguide meets the qubit to 10 millikelvin, the risk of errors in our qubits is reduced drastically,&quot; says Per Delsing, Professor at the Department of Microtechnology and Nanoscience, Chalmers University of Technology, and leader of WACQT.</div> <div><br /></div> <div>Accurate temperature measurement is also necessary for suppliers who need to be able to guarantee the quality of their components, for example cables that are used to handle signals down to quantum states.</div> <h2 class="chalmersElement-H2">New opportunities in the field of quantum thermodynamics</h2> <div>Quantum mechanical phenomena such as superposition, entanglement and decoherence mean a revolution not only for future computing but potentially also in thermodynamics. It may well be that the thermodynamic laws somehow change when working down at the nanoscale, in a way that could one day be exploited to produce more powerful engines, faster-charging batteries, and more.</div> <div><br /></div> <div>&quot;For 15-20 years, people have studied how the laws of thermodynamics might be modified by quantum phenomena, but the search for a genuine quantum advantage in thermodynamics is still open,&quot; says Simone Gasparinetti, who recently started his own research group and plans to contribute to this search with a novel range of experiments.</div> <div><br /></div> <div>The new thermometer can, for example, measure the scattering of thermal microwaves from a circuit acting as a quantum heat engine or refrigerator.</div> <div><img src="/SiteCollectionImages/20210101-20210631/Marco%20Scigliuzzo%20(2).jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 10px;width:180px;height:157px" /><br />&quot;Standard thermometers were fundamental for developing classical thermodynamics.

The emitter is strongly coupled to the end of the waveguide being tested. Thermal photons in the waveguide lead to a measurable drop in the coherently scattered signal, which is recorded continuously. In this way, the number of photons in the propagating mode of the microwave waveguides can be read – this corresponds to a temperature. The Chalmers researchers’ implementation, which uses a superconducting circuit operated at gigahertz frequencies, offers simplicity, large bandwidth, high sensitivity, and negligible power dissipation.<br /></span><span style="background-color:initial"><br /><b>More about: The Wallenberg Centre for Quantum Technology</b></span></div> <div><span style="background-color:initial"><div><a href="/en/centres/wacqt/Pages/default.aspx">The Wallenberg Centre for Quantum Technology​</a>, WACQT​, is a 12 year research center that aims to take Sweden to the forefront of quantum technology.

But can we out a prize on water or is it invaluable? With an ongoing research project, researchers at Chalmers are trying to learn more.</b></p><div>​Through the <a href="/en/projects/Pages/Risk-based-prioritization-of-water-protection-in-sustainable.aspx">WaterPlan project</a>, researchers from the DRICKS center at the Department of Architecture and Civil Engineering are investigating what the need to protect our water resources looks like and how Swedes value this protection. Part of the project means that the researchers will use surveys to investigate and map how people prioritize and what they are actually willing to pay to protect our drinking water sources.         </div> <div> </div> <div>&quot;Today knowledge about how Swedes relate to our common water and how to value it is scarce. We know from studies in other Scandinavian countries that people prefer that the water they drink is naturally clean, that it doesn’t need to be purified afterwards. And that is of course important for how the protection of water resources is designed,&quot; says<a href="/en/staff/Pages/andreas-lindhe.aspx"> Andreas Lindhe,</a> associate professor and researcher at the DRICKS centre, Department of Architecture and Civil Engineering.    </div> <div> </div> <h2 class="chalmersElement-H2">The great value of water in society    </h2> <div>Our surface and groundwater resources, ie water in lakes and streams as well as the water under the ground, not only provide us with drinking water but offer people so much more. Our water resources are, among other things, sources for energy production, irrigation and recreation – when we go swimming or boating in the summer.        </div> <div> </div> <div>&quot;By protecting our water resources from a drinking water perspective, we can also protect these other values, so-called services, that they provide, but it can also mean restrictions on how we can use these services.&quot;    </div> <div> </div> <div>Therefore, the WaterPlan project also maps and analyzes the various services that water resources provide and the natural conditions on which they depend. The purpose is for researchers to be able to create an overall picture of how we use our water resources and how we thereby value them, as a basis for being able to better prioritize protection measures.      </div> <div> </div> <h2 class="chalmersElement-H2">Pricing that does not reflect fair value     </h2> <div><span style="background-color:initial">DRICKS works closely with Swedish drinking water producers. The industry sees a need to increase water and sewage tariffs in order to be able to maintain and develop drinking water and wastewater management. The Swedish tariff is based on the prime cost principle, which results in a cost that in itself cannot be said to correspond to the actual value of the water and sewage services that we use in society. But what can be the disadvantages of water being underestimated and therefore priced too low?       </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">&quot;The fact that water in Sweden is inexpensive is not a bad thing since we want water to be available to everyone. But the low price of water means that we become worse at economizing it and tend to take it for granted. For a sane management of water, it is therefore bad that water is inexpensive&quot;</span><span style="background-color:initial">, says Andreas Lindhe.  </span></div> <div><span style="background-color:initial"><br /></span></div> <div> </div> <div>Water is a prerequisite for life and crucial for our society in many ways. Andreas Lindhe believes that expressing risks and evaluating measures of action based on socio-economic consequences does not aim to reduce the importance of water – but on the contrary provides an opportunity to emphasize the importance of water, for instance when balancing competing interests.    </div> <div> </div> <div><br /></div> <div> </div> <div>&quot;But we must of course be aware that there are other aspects than the purely socio-economic ones that may need to be considered when important decisions about water are to be made&quot;, Andreas Lindhe concludes.    <br /><br /><em>The </em><a href="https://www.worldwaterday.org/" target="_blank"><em>World Water Day</em></a><em> is an initiative from the UN that started in 1993 and which draws attention to the importance of water in society.
