Simply put, the genetic code in DNA is transcribed to the molecule messenger RNA (mRNA), which tells the cell's factory which protein to produce and in which quantities.</span></div> <div>Researchers have put a lot of effort into trying to control gene expression because it can, among other things, contribute to the development of protein-based drugs. A recent example is the mRNA vaccine against Covid-19, which instructed the body's cells to produce the same protein found on the surface of the coronavirus. The body's immune system could then learn to form antibodies against the virus. Likewise, it is possible to teach the body's immune system to defeat cancer cells or other complex diseases if one understands the genetic code behind the production of specific proteins. </div> <div> </div> <h2 class="chalmersElement-H2">&quot;The DNA controls the quantity of a specific protein&quot;</h2> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/Bio/SysBio/Aleksej%20Zelezniak.jpg" alt="Aleksej Zelezniak" class="chalmersPosition-FloatRight" style="margin:5px 15px" />Most of today's new drugs are protein-based, but the techniques for producing them are both expensive and slow, because it is difficult to control how the DNA is expressed.  Last year, a research group at Chalmers, led by <strong>Aleksej Zelezniak,</strong> Associate Professor of Systems Biology, took an important step in understanding and controlling how much of a protein is made from a certain DNA sequence.</div> <div> </div> <div>&quot;First it was about being able to fully ‘read’ the DNA molecule's instructions. Now we have succeeded in designing our own DNA that contains the exact instructions to control the quantity of a specific protein&quot;, says Aleksej Zelezniak about the research group's latest important breakthrough. </div> <div> </div> <h2 class="chalmersElement-H2">DNA molecules made-to-order</h2> <div> </div> <div>The principle behind the new method is similar to when an AI generates faces that look like real people. By learning what a large selection of faces looks like, the AI can then create completely new but natural-looking faces. It is then easy to modify a face by, for example, saying that it should look older, or have a different hairstyle. On the other hand, programming a believable face from scratch, without the use of AI, would have been much more difficult and time-consuming. Similarly, the researchers' AI has been taught the structure and regulatory code of DNA. The AI then designs synthetic DNA, where it is easy to modify its regulatory information in the desired direction of gene expression. </div> <div> </div> <div>Simply put, the AI is told how much of a gene is desired and then  ‘prints’ the appropriate DNA sequence. </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/Bio/SysBio/Jan%20Zrimec_200%20px.jpg" alt="Jan Zrimec" class="chalmersPosition-FloatRight" style="margin:5px 15px" />“DNA is an incredibly long and complex molecule. It is thus experimentally extremely challenging to make changes to it by iteratively reading and changing it, then reading and changing it again. This way it takes years of research to find something that works. Instead, it is much more effective to let an AI learn the principles of navigating DNA. What otherwise takes years is now shortened to weeks or days”, says first author <strong>Jan Zrimec</strong>, a research associate at the National Institute of Biology in Slovenia and past postdoc in Aleksej Zelezniak’s group.</div> <div> </div> <h2 class="chalmersElement-H2"></h2> <h2 class="chalmersElement-H2">Efficiant development of proteins<span></span></h2> <p class="chalmersElement-P">The researchers have developed their method in the yeast <em>Saccharomyces cerevisiae</em><span>, whose cells resemble mammalian cells.

Some are so expensive that it is impossible to obtain a return on investment, making them economically nonviable. With our technology, it is possible to develop and manufacture proteins much more efficiently so that they can be marketed&quot;, says Aleksej Zelezniak.</div> <div> </div> <div><strong>Text: </strong>Karin Wik<br /><strong>Illustration: </strong>Unsplash &amp; Pixabay</div> <div> </div> <div><br /></div> <div> </div> <div><strong>Read the study:</strong> <span style="background-color:initial"><a href="https://www.nature.com/articles/s41467-022-32818-8">Controlling gene expression with deep generative design of regulatory DNA</a></span></div> <div> </div> <div><ul><li><span style="background-color:initial">T</span><span style="background-color:initial">he authors of the study are Jan Zrimec, Xiaozhi Fu, Azam Sheikh Muhammad, Christos Skrekas, Vykintas </span><span style="background-color:initial">Ja</span><span style="background-color:initial">uniskis</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial">, N</span><span style="background-color:initial">ora K.

It is this form of copper ions that is most common in living cells. It's an important discovery because reduced copper, while it is needed in the body, also contributes to redox-reactions that damage − or even kill −​ the cells.

But it’s not only humans that can catch a cold. A recently published paper shows that bacteria in wastewater treatment plants can also catch a cold every once in a while. </b></p>​In wastewater treatment plants, the work is often done by bacteria, who carry out biological processes used to break down the pollutants and purify the water. Like bacteria, viruses are everywhere around us, and the fact is that bacteria just like other living things can be infected by viruses. <a href="/en/Staff/Pages/oskar-modin.aspx" target="_blank">Oskar Modin</a>, Professor at the Water Environment Technology Division, Department of Architecture and Civil Engineering, has tested the thesis that a wastewater treatment plant can catch a cold.    <br /><br /> – A large treatment plant has billions of bacteria that work in a treatment process called activated sludge. <img src="/SiteCollectionImages/Institutioner/ACE/profilbilder/Oskar-Modin_170x170.jpg" class="chalmersPosition-FloatRight" alt="Oskar Modin" style="margin:5px" /><br />The bacterial communities are constantly exposed to viruses that infect them, so the question we asked ourselves was whether the process can periodically be more exposed and what happens then, says Oskar Modin.    <br /> <div><h2 class="chalmersElement-H2">Connection between virus and emissions</h2></div> Oskar and fellow researchers measured the concentration of virus particles that were released from four different wastewater treatment plants in Sweden and compared it with how much organic carbon was released at the same time.    <br /><br /> – When we measured virus particles in the water, we found a connection between viruses and organic carbon – when there were more viruses, there was also more organic carbon in the outgoing water.    <br /> <div><h2 class="chalmersElement-H2">Important to control the biologial processes </h2></div> Removal of dissolved organic carbon from wastewater is important as it would otherwise lead to increased oxygen consumption where the purified water is discharged, affecting the aquatic environment nearby. The fact that the treatment plant's smallest workers can catch a cold and as a result perform worse, is important to investigate further. Not least to be able to prevent or relieve the symptoms and thereby maximise the effectiveness of the bacteria. But tea with honey, or home remedies with ginger and lemon won’t do when it comes to bacteria.    <br /><br /> – Viruses are often specialised in a certain species, which means that humans and bacteria cannot be infected by the same virus. One possible way to influence the number of viruses in treatment plants could be to adjust the way the treatment plant is operated. We saw differences between the treatment plants in the study, which we believe may be related to the design or control of the biological treatment processes, says Oskar.    <br /><br />Researchers do not yet know exactly how the cold manifests itself in the bacteria and to what extent the virus affects the purification processes. Oskar and his colleagues continue to investigate the question in other systems where viruses and bacteria interact, and hope to look at a longer period of time and whether season, temperature and other factors have any significance.    <br /><div><br /></div> <div><h3 class="chalmersElement-H3">About the research</h3></div> The paper “<a href="https://doi.org/10.1016/j.wroa.2022.100146" title="doi" target="_blank">A relationship between phages and organic carbon in wastewater treatment plant effluents</a>” was published in Water Research X in August 2022, and written by Oskar Modin, Nafis Fuad, Marie Abadikhah, David l’Ons, Elin Ossiansson, David J.

By working with real cases from healthcare, the master students have been able to use their theoretical knowledge in practical applications – and at the same time given the healthcare managers valuable insights.</b></p><div>​In a joint project between Chalmers and Region Västra Götaland, two existing educations at different levels are integrated to create a cross-fertilization that can ultimately benefit patients and society. The students come from the master's programme Quality and Operations Management, while the managers in the Region Västra Götaland take a course in quality-driven operations development. The course is given by the Centre for Healthcare Improvement at Chalmers.</div> <div> </div> <div>One of the master's students who participated in the initiative is Johan Blickhammar, who has come a long way in his engineering studies. He is positive about this collaborative approach in education.<br /><br /></div> <div> </div> <div><span><span><span><span><img src="/sv/institutioner/tme/nyheter/PublishingImages/johan_blickhammar.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:10px" /><span style="display:inline-block"></span></span></span></span></span>“It was exciting! Partly because of the Region Västra Götaland and the important role that healthcare plays in the society, and also that we worked with existing and upcoming challenges. It was interesting to test and apply theories to real problems and very inspiring to take part in and contribute to the region's development and improvement work.”</div> <div> </div> <div>Even in typical classes at Chalmers there is a lot of interaction between companies and students, but usually about gaining understanding and gathering knowledge about operations and methods for solving problems, says Johan. Here it was done in a more integrated way. </div> <div> </div> <div>“This initiative differed in that we students worked in collaboration and exchanged knowledge with the healthcare managers to solve present and future problems. The challenge lay mainly in the complexity that often comes with real problems, trying to identify the underlying problems and create proposals to address them in a practical, efficient, and sustainable way”, says Johan Blickhammar, and adds:</div> <div> </div> <div>“Improvement knowledge is very much about problem solving. This work has reinforced the understanding that knowledge, communication, and information are central to problem solving and improvement work.”</div> <div> </div> <h3 class="chalmersElement-H3">&quot;Contributed with approaches that we didn't think about&quot;</h3> <div> </div> <div><span><span><img src="/sv/institutioner/tme/nyheter/PublishingImages/hans_gunnarsson.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:15px 10px" /><span style="display:inline-block"></span></span></span>Hans Gunnarsson is a section manager of palliative care at Högsbo Hospital, which is part of the Sahlgrenska University Hospital. From his perspective, he also sees advantages in the approach.<br /><br /></div> <div> </div> <div>“It felt like a privilege to be interviewed by the students. They contributed with approaches that I did not think about, and that were taken for granted for me. I’m now aware of the need of clarifications and  and further explanations. It is easy to think that others have the same perspectives as you, and know and can do the same things as you. So there were adequate questions, like, ’when does the process start and when does it end’? They asked many questions that made me reflect and clarify elements, activities and definitions. I thought they were veryclever and insightful.”</div> <div><br /></div> <div> </div> <div>He has also made several lessons of his own:</div> <div> </div> “In a quality improvement project like this, it is important to be careful with the background work. It is very important to spend time defining and understanding the problem that needs to be improved, to pause for a while in the planning phase and acquire different perspectives.” <div> </div> <div><br /></div> <div> </div> <div>“I also felt a bit old! The students were quick in both thought and language. I thought my English was decent – I don't think so anymore. They spoke English completely unhindered and seemed to use terms for quality development naturally. I was impressed by them,” says Hans Gunnarsson.<br /><br /></div> <div> </div> <h3 class="chalmersElement-H3">Complex problems require many perspectives</h3> <div> </div> <div>Student Johan Blickhammar believes that the challenges of the present and the future are often about technological development, and that Chalmers has an important role to play in contributing to the surrounding society.<br /><br /></div> <div> </div> <div>“The majority of the problems that we were presented forcould be related to digital</div> <div>transformation. For many operations, not just the Region Västra Götaland, this means a big change as people today interact with technical solutions to an increasing extent. This is a complex problem that, among other things, requires that many different perspectives are taken into account.

Research from Chalmers show that resources like noise-cancelling headphones and absorbent materials can create well-being, but above all highlights the importance of letting the concept of healthy activity-based offices develop over time, and in dialogue with users.</b></p><div>​Melina Forooraghi, Doctor at the Department of Architecture and Civil Engineering, has explored factors that make us feel well in an activity-based office environment and how design characteristics can help the user to stay healthy. Her findings highlight the importance of enabling coping with stressors in the office environment by providing a wide range of solutions – from noise-cancelling headphones to divider screens, noise absorbent materials and quiet rooms.    </div> <div> </div> <div> – A healthy activity-based office provides users with access to the resources they need to function and feel well, and is designed so that users understand how they can use and benefit from different types of workspaces, says Melina Forooraghi.    </div> <div> </div> <div>The users need resources to handle both disturbing sounds and visual impressions and means to function socially with colleagues and receive support from managers in the daily work. She emphasizes that it is of great importance to be able to see the activity-based office as moving projects that can continue to develop over time by testing different solutions and working with adaptation and remodeling.    </div> <div> </div> <div> – The management need to be in constant dialogue with the users. The fact that the construction work is finished is not synonymous with the office environment being finished to the extent that it doesn’t require more attention, says Melina.    </div> <h2 class="chalmersElement-H2">Designing for everyone is designing for no one    </h2> <div>In her research, Melina has focused on factors that can create health rather than factors that cause ill health, but she can clearly see what should be avoided: standardized design solutions. Relocations to activity-based offices are often linked to organizational mergers where people from different backgrounds, disciplines and with different tasks are brought together to work in the same space. Organizations often fail to include employee perspectives in the process, which in turn results in more generic office design that must respond to a variety of needs and differences.    </div> <div> </div> <div> – Standardized and generic design solutions are a lost opportunity because designing for everyone is the same as designing for no one. If you keep your design at a very generic level, it means it doesn't really serve anyone, says Melina.    </div> <h2 class="chalmersElement-H2">The office environment of the future    </h2> <div>The trend in office real estate is towards more activity-based offices where users share workspaces. After the pandemic, more and more organizations have adopted hybrid work, which can also lead to increased acceptance of desk sharing as many spend less time in the office. In the longer term, Melina sees further trends:    </div> <div> </div> <div> – I believe that much of the work we do today will be automated in the future, which requires us to develop our uniquely human abilities such as design, imagination, critical thinking and innovation. The office environment will be a catalyst for these skills and constitute an environment that promotes these types of activities, concludes Melina.      </div> <div> </div> <div>Melina Forooraghi recently defended her doctoral thesis: <a href="https://research.chalmers.se/publication/531470">Healthy Offices: Conceptualizing Healthy Activity-based Offices</a>   </div> <div><br />Text: Catharina Björk<br /></div>Thu, 20 Oct 2022 00:05:00 +0200https://www.chalmers.se/en/areas-of-advance/health/news/Pages/Thesis-projects-addressing-healthcare-needs.aspxhttps://www.chalmers.se/en/areas-of-advance/health/news/Pages/Thesis-projects-addressing-healthcare-needs.aspx​Thesis projects addressing the needs of the healthcare sector<p><b>​On 12th October, Chalmers hosted a master’s and bachelor’s thesis fair in health and technology at Johanneberg Campus.

This is also the case when laser light is shined onto a mirror. The reflected light field contains information about the mirror’s position. This measurement scheme is for example used in gravitational wave detectors. The information about the mirror’s position can be vastly increased by capturing the light between two mirrors, in so-called cavity optomechanical systems. These systems not only enable measuring the position of the mirror very precisely, but also controlling its motion, even to its quantum mechanical ground state. This has fascinated scientists as it allows exploring the validity of quantum physical laws for larger objects. The next major challenge in this research field is to increase the interaction between light and the motion of the mirror until it is possible to create quantum mechanical states of the mirror directly. </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">The aim of this project is to reach the so-called nonlinear regime of quantum optomechanics in chip-based devices. Then, single light particles (photons) and the quantized motion of the mirror (phonons) are linked to each other in a controlled way. If one succeeds with this ambitious goal, one can, for instance, detect individual photons without destroying them and the quantum information that they carry. An important area of application of this ability lies in the field of quantum technology. For example, having access to the nonlinear regime could lead to the development of novel chip-based devices that can detect significantly smaller forces and displacements than what the most advanced technologies allow us to do today.<span> </span> </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Grant: </strong>SEK 27,000,000 over five years </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Principal investigator:</strong> Associate Professor <a href="/en/staff/Pages/witlef-wieczorek.aspx">Witlef Wieczorek​</a>, Department of Microtechnology and Nanoscience (MC2)</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Co-applicants in the project:</strong> Andreas Isacsson and Philippe Tassin (Physics) and Janine Splettstoesser (MC2), and encompasses Chalmers' expertise in experiment, theory, and artificial intelligence. </p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><strong>Read more: </strong><a href="https://kaw.wallenberg.org/en/research-projects-2022">KAW Research Projects 2022</a></p> <div> </div> <p class="chalmersElement-P"> ​</p>Fri, 14 Oct 2022 09:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/Can-3D-printed-food-alleviate-age-related-malnutrition.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Can-3D-printed-food-alleviate-age-related-malnutrition.aspxCan 3D printed food alleviate age-related malnutrition?<p><b>​Age-related malnutrition is a serious problem that is primarily caused by insufficient food intake. Over the age of 70, more than 40 percent of the population will suffer from swallowing problem. Research shows that a diet with customized texture and taste makes swallowing easier for those, and that 3D printed food can make meals more appetizing, all with the help of materials science.</b></p><div>Insufficient food intake can have more causes than dysphagia, the medical term for swallowing disorders, but it is a very common problem for the elderly. It risks leading to age-related malnutrition that makes us more frail, which often leads to lack of independence, fall accidents and hospitalization. It not only causes suffering for the individual, but also entails great costs for society. In Sweden alone, the cost of age-related malnutrition is estimated to SEK 9 billion annually.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/3D-printadmat_MatsStading_02.jpg" alt="Mats Stading" class="chalmersPosition-FloatRight" style="margin:5px 15px;width:367px;height:260px" />Mats Stading studies how materials science can be used to produce food that is easy to chew and swallow, but still resembles ordinary food as much as possible. It starts with producing a slow-flowing, so-called viscoelastic paste with different textures and flavors adapted to personal needs. 3D-printed food is produced by &quot;printing&quot; the paste into shapes similar to regular food, and then baking it to a firm, but easily chewable and swallowable consistency.</div> <div><br /></div> <div> </div> <div><br /></div> <div> </div> <div>“The research results clearly show that food consistency can be modified making it easier to both chew and swallow safely, and still remaining tasty.

The technology exists and as has been proven to work, but there are a number of measures required for it to work in clinical or home setting. An important part is that food producers are involved and develop products that can be used on a larger scale.</div> <div><br /></div> <br /><div> “In the future, 3D printed food will probably be a regular feature, but initially extra support may be required if something goes wrong.

But how can healthcare managers handle these management innovations in a way that results not only in pretty words but in actual improvements? Christian Colldén is a physician and healthcare manager who in his doctoral thesis at Chalmers has studied how management innovations can be understood and translated into a local context to improve the quality and efficiency of care.</b></p><h3 class="chalmersElement-H3">​What challenges do you focus on in your research?</h3> <div>&quot;All those who have tried to improve healthcare systems have probably realised that it is a very challenging undertaking. Demands often come from many directions, strong professions with diverse opinions and views are to be brought on the same track, and processes are seldom straight and separate. Management innovations are often presented as comprehensive and consummate concepts, which will solve the problems of healthcare, but earlier research have shown that they often do not deliver the promised improvements. Healthcare professionals also often meet management innovations with skepsis. On the other hand, there are examples of management innovations being positively received and resulting in improved quality and efficiency. The challenge that I focus on is how managers can improve the complex healthcare systems that they act in, and how management innovations can become useful tools in that work.&quot;</div> <h3 class="chalmersElement-H3">How do you address the problem with your research?</h3> <div>&quot;I have been inspired by action research, which implies that I have tried to achieve improvements in my own context at the same time as I have collected data to analyse what me and my colleagues have done in practice. I have worked in psychiatry within the Sahlgrenska University Hospital and, hopefully, the projects have created better conditions for innovativeness quality improvements. At the general level I try to contribute to a better understanding of how to use management innovations so that they are positively received by different actors in healthcare and create improvements. That general knowledge can be used in education for managers and staff who support managers in development and improvement work.&quot;</div> <h3 class="chalmersElement-H3">What are the main findings?</h3> <div>&quot;Different actors in healthcare, like nurses, physicians, politicians, and care developers, have different views on what quality in care means, how care should be provided in a high-quality fashion, and how improvements can be achieved. Thus, they can be seen to rely on different logics. In the same way, different management innovations rely on one or several logics. By mapping underlying logics, healthcare managers can create an appreciation for the complex system and match concepts with the context.&quot;</div> <div> </div> <div>&quot;Next, managers should translate rather than implement management innovations, which implies that one should view them not as fixed concepts but as mouldable ideas. A concrete example is Value-based Healthcare, which can be seen as relying on both a logic of standardisation (of care processes for defined patient groups) and a logic of goal orientation (that if we measure outcomes and costs, the manager need not decide how the result is to be achieved). Based on the understanding of what is needed and/or will be best received in the specific organisation, different aspects of management innovations can be emphasized to make a positive impact and drive change. Management innovations in themselves seldom solve the problems but they can be used as strategic tools and sources of inspiration.&quot;</div> <h3 class="chalmersElement-H3">What do you hope your research will lead to? </h3> <div>&quot;Unfortunately, there are no shortcuts to improvements in healthcare, but research can provide some advise on how to take on the task. For example, appreciation of the surrounding system and its components – especially what drives the individuals that you want to involve in new ways of working. I hope that managers and others who drive development in healthcare can adopt that approach and that it is also highlighted in management training programmes, by internal support functions for care development, and by external consultants. If this view gains impact, I believe that frustration can be turned into constructiveness and real improvements.&quot;</div> <div> </div> <div><br /><br /></div> <div> </div> <div><em>Text compilation: Daniel Karlsson</em><br /></div> <div> </div> <div><br /></div> <div>Read the thesis <a href="https://research.chalmers.se/en/publication/?id=531610" target="_blank">&quot;Managing management innovations: Contextual complexity and the pursuit of improvements in healthcare&quot;</a></div> <div> </div> <div>The author will defend the thesis on 7 October 2022 at 13.15, see link on the <a href="https://research.chalmers.se/en/publication/?id=531610" target="_blank">thesis’ page</a><br /></div> <div> </div> <div><br /></div> <div> More about <a href="/en/Staff/Pages/christian-ohrn.aspx">Christian Colldén</a></div> <div> </div>Thu, 29 Sep 2022 09:00:00 +0200https://www.chalmers.se/en/news/Pages/Research-from-Chalmers-heading-for-Silicon-Valley---.aspxhttps://www.chalmers.se/en/news/Pages/Research-from-Chalmers-heading-for-Silicon-Valley---.aspxResearch from Chalmers heading for Silicon Valley<p><b>​Every year the Swedish innovation agency Vinnova selects research projects for the exclusive incubator program Reach with focus on technology relevant for the ecosystem in Silicon Valley and with the potential to be commercialised.

Together with the triathlete Mårten Fryknäs, Olof Sköld had identified that many athletes suffered from difficult digestion problems, because they have to consume large amounts of sugar to be able to perform on a high level. Olof Sköld had heard about Anna Ström´s expertise and contacted her. They started to discuss how this problem could be solved, based on Anna Ströms long research on polysaccharides. P<span style="background-color:initial">olysaccharides is different</span><span style="background-color:initial"> sorts of sugar that are stuck together. </span></div> <span></span><div><br /></div> <div>“Our discussions and the collaboration became very interesting.

In that way the sugar was picked up by the body when it reached the intestinal which made it possible for the athletes to consume a lot of sugar in a short time, without feeling sick. In collaboration with her colleague Luca Marciani in the UK and thanks to a grant from Chalmers Innovation Office, Anna Ström could do a study to verify the research with humans. <a href="https://pubs.rsc.org/en/content/articlelanding/2019/fo/c9fo01617a" title="Link to the scientific article Alginate and HM-pectin in sports-drink give rise to intra-gastric gelation in vivo">The study was published in the scientific journal Food and Function</a>.</div> <div><br /></div> <div>“By using MRI (Magnetic resonance imaging), we could see that we got a gel in the stomach that was dissolved in the intestine. We also saw that the gel itself prevented the absorption of sugar, by measuring the participants the blood sugar. They were not professional athletes, but the study showed that the concept worked, explains Anna Ström <br /><span style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;font-size:20px;background-color:initial">​</span></div> <div>They had a recipe for the beverage which made it possible to apply for a patent. Olof Sköld founded the company Maurten that owns the patent. After this stage Anna Ström has not been personally involved more in the beverage, but other researchers have done more studies which have provided various answers on the hydrogels effect. This hasn’t stopped the beverage from becoming popular in the sports world. <br /><br /></div> <div>“Many athletes have tried the beverage and continued to use it because they think it works. But now there is also a scientific article that more clearly confirms the hydrogels positive effects on the stomach problems and the performance.<a href="https://pubmed.ncbi.nlm.nih.gov/34334720/" title="Read the article Glucose and Fructose Hydrogel Enhances Running Performance, Exogenous Carbohydrate Oxidation, a"> The study was done by independent researchers in England, Australia and Scotland and was published in January this year</a>&quot;, says Anna Ström. </div> <h2 class="chalmersElement-H2">Price for impact in society puts the research in the spotlight </h2> <div>As researcher Anna Ström has chosen the approach &quot;act but not to be seen&quot;. She is more comfortable with that role, but she is confident that she would have got more attention if she had whished for it. When she now gets Chalmers Impact Award the withdrawn approach will be changed a bit. <br /><br /></div> <div>&quot;Of course, it is very nice and an honor to get this award. I share it with Olof Sköld and a lot of other people, but it feels good to be fronting our work in this context&quot;, says Anna Ström</div> <div><br /></div> <div>More information, contact </div> <div><a href="/en/Staff/Pages/anna-strom.aspx" title="Link to Anna Ström personal profile page ">Anna Ström</a>, Professor at the Department for Chemistry and Chemical Engineering</div> <div><br /></div> <div>​​​​Text: Jenny Holmstrand <br />Photo: Chalmers/Sara Salehi</div> ​​​Thu, 15 Sep 2022 11:00:00 +0200
