Other West Sweden collaborators in addition to Chalmers include Västra Götalands Region, Sahlgrenska Academy and Antaros Medical, who are all working to avoid toxicity in humans during drug development.<br /><br />The objective of the project is to validate or qualify translational imaging methods as potential imaging biomarkers. The imaging biomarker qualification will be specifically addressed in three areas with a high unmet medical need: the assessment of liver toxicity, lung toxicity and the bio-distribution of biologics. The in-kind contributions to the project of around EUR 12 million by the industrial partners are complemented by IMI-funding in a total budget of EUR 24 million. TRISTAN is led by Bayer and coordinated by the European Organisation for Research and Treatment of Cancer (EORTC), who also leads one imaging biomarker qualification study for cancer drug induced interstitial lung disease. <br /><br />Imaging techniques are firm components of today’s medical practices, just as the use of biomarkers has become commonplace in pre-clinical and clinical research. However, imaging biomarkers are not widely used in the drug discovery process although they could advance drug safety evaluation, both for pre-clinical and clinical development. Imaging biomarkers have the potential to improve translatability of pre-clinical (animal) data to healthy volunteers and patients and thus could help avoid late stage attrition of development programmes. In addition, functional diagnostic imaging methods used as biomarkers would offer the possibility to confirm drug toxicity mechanisms in humans, including the potential to determine drug-drug interactions. <br /> <br />Data relevant for validation of methods addressed in the project and aggregated data will be made publicly available in compliance with data privacy laws. Significant interactions with existing imaging biomarker initiatives as well as with regulatory authorities will have a strong impact on the future value of imaging biomarker procedures. To sustainably offer access to the validated imaging biomarkers, the three project SME partners are planning to offer respective biomarker imaging services commercially. <br /><br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/New%20project%20on%20imaging%20techniques%20in%20drug%20safety%20assessment/Tristan_IMG_7682_340px.jpg" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><em>“We are very proud of being a partner in the TRISTAN consortium and that our MRI-models are used to find biomarkers to better predict toxicity in humans in drug development&quot;, says Paul Hockings, Adjunct Professor at Chalmers University of Technology and at MedTech West</em><em>, and Per Malmberg, researcher in Analytical Chemistry at Chalmers University of Technology.</em><br /> <br /><strong>About Imaging Biomarkers </strong><br />An imaging biomarker is a functional radiographic imaging procedure utilising imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Positron Emission Tomography (PET). In research and development, imaging biomarkers are used as characteristics to objectively measure biological processes, pathological changes, or pharmaceutical responses to a therapeutic intervention. They have the advantage of remaining non-invasive and being spatially and temporally resolved. Imaging biomarkers have the potential to improve translatability of animal data to healthy volunteers and patients, thereby helping to improve our understanding of drug mechanisms, interactions and metabolic processes. <br /><br /><strong>About the Innovative Medicines Initiative (IMI) </strong><br />The Innovative Medicines Initiative (IMI) is working to improve health by speeding up the development of, and patient access to, innovative medicines, particularly in areas where there is an unmet medical or social need. It does this by facilitating collaboration between the key players involved in healthcare research, including universities, the pharmaceutical and other industries, small and medium-sized enterprises (SMEs), patient organisations, and medicines regulators. IMI is a partnership between the European Union and the European pharmaceutical industries, represented by the European Federation of Pharmaceutical Industries and Associations (EFPIA). Through the IMI 2 programme, IMI has a budget of EUR 3.3 billion for the period 2014-2024. Half of this comes from the EU’s research and innovation programme, Horizon 2020. The other half comes from large companies, mostly from the pharmaceutical sector; these do not receive any EU funding, but contribute to the projects ‘in kind’, for example by donating their researchers’ time or providing access to research facilities or resources. <br /><br />The research leading to these results received funding from the Innovative Medicines Initiatives 2 Joint Undertaking under grant agreement No 116106.

By using a composite with added graphene, the hull is made stronger and lighter. Hydrofoils are added to lift the boat, decreasing drag and allowing greater speeds. After tests performed in SSPAs towing tank, the dinghy was ready to be tried out at sea for the first time.</b></p>​A relatively new occurrence within the sailing world is to mount hydrofoils on small sailing dinghies. Chalmers and SSPA wanted the challenge to do this on “the world´s least advanced sailboat” – the optimist dinghy. The main question and problem for the students and the researchers of this project has been: can an optimist foil and how will this be done? <br /> <br />The optimist dinghy has, since it was conceived in 1947, become one of the world’s most popular sailing dinghies, with over 150 000 boats registered. The boat, only 2.3 metres in length and with a sail area of 3.3 square metres, is normally limited to speeds below 4 knots. <br /> <br />However, by building the boat in carbon fiber and graphene, and fitting it with hydrofoils lifting the hull out of the water, the hydrodynamic resistance can be reduced dramatically. <br /> <br />The hydrofoils, constructed and tested at SSPA, allowed the optimist dinghy to sail as fast as the wind in the recently conducted sea trials, achieving a maximum boat speed of 12 knots in only 12 knots of wind.<br /><br />Watch a video about <a href="">the premiere of the foiling optimist</a><br /><br /><strong>For more information, please contact:</strong><br />Christian Finnsgård, +46- 31 772 1353, <a href=""></a>Fri, 07 Apr 2017 00:00:00 +0200 and touch mediate sensations via osseointegrated prostheses<p><b>​ A new study has found that people with a prosthesis attached directly to their skeleton can hear by means of vibrations in their implant. This sound transmission through bones is an important part of osseoperception – sensory awareness of the patient’s surroundings provided by their prosthesis. This discovery sheds new light on the tactile and auditory perception of humans and can be used to develop improved prostheses.</b></p>​How can we help amputees regain tactile sensations and other natural feelings while grasping an object or walking on uneven ground?<br /><br />An international group of researchers in Sweden and Italy offers a new answer. They have demonstrated for the first time that patients with implanted osseointegrated prostheses (ones attached directly to the skeleton) are able to perceive external stimuli better by hearing through their limb implants.<br /><br />The investigation was conducted jointly in Sweden by Chalmers University of Technology, Sahlgrenska University Hospital, and the University of Gothenburg; all collaborating closely with Scuola Superiore Sant’Anna in Italy.<br /><br />In a recent paper in <em>Nature Scientific Reports,</em> the researchers presented a discovery that opens up new scenarios for developing novel artificial limbs. Even though the transmission of sound through skull bones is a well-known phenomenon, widely studied by Professor Bo Håkansson at Chalmers who was a participant in this study, it was not clear whether this also occurs through bones in the arms and legs and thus contribute to osseoperception – “feeling” arising from the mechanical stimulation of an osseointegrated prosthesis.<br /><br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Hearing%20and%20touch%20mediate%20sensations%20via%20osseointegrated%20prostheses/Max-Ortiz-Catalan_S8A7544-1_180px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br />“Until now, the consensus was that the sense of touch played the primary role in osseoperception for patients with artificial limbs fixated into their skeletons”, says Max Ortiz Catalan, head of the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers and supervisor of the research.<br /><br /><br /><br />Francesco Clemente, who conducted the experiments as a visiting PhD student at BNL from the Biorobotics Institute of Scuola Superiore Sant’Anna, comments:<br /><br />“Using four different psychophysical tests, we have demonstrated that even subtle sensory stimuli can travel through the body and be perceived as sound. This hearing increases the individual’s sensory awareness, even in patients with osseointegrated implants in their legs.”<br /><br />These results show that osseointegration, which allows for stable mechanical attachment of robotic prostheses directly to the skeleton through a titanium implant, improves patients’ functionality, comfort, and ability to perceive the world around them.<br /><br />The researchers tested twelve patients with various degrees of amputation, both upper and lower limb amputees. All tests indicated that patients could perceive mechanical vibrations applied to their titanium implants, through hearing as well as touch. In particular, and synchronously with the vibrations in their arms or legs, patients reported audible sound. During the experiments, the researchers found that subjects with osseointegrated prostheses could perceive very small stimuli and react more quickly to them due to additional perception by hearing.<br /><br />“In practice, the stimuli received by the patients are perceived more strongly and carry more information because they are composed of two modalities; touch and hearing,” says Max Ortiz Catalan. “This is an important step forward in understanding the osseoperception phenomenon and, more generally, the tactile and auditory perception of humans. This discovery may offer a new starting point for implementing novel prostheses that provide enriched sensory feedback to the user.”<br /><br />Read the article in <span><em>Nature Scientific Reports:<br /><span style="display:inline-block"></span></em></span><span></span><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Touch and Hearing Mediate Osseoperception</a><br /><br /><strong>For more information, please contact:</strong><br />Max Ortiz Catalan, Department of Signals and Systems, Chalmers University of Technology, Sweden.<br />Tel: +46 70 846 10 65, <a href=""></a><br /><br /><strong>Facts about the research</strong><br />The investigation was conducted jointly in Sweden by the Signals and Systems Department at Chalmers University of Technology, the Centre for Advanced Reconstruction of Extremities at Sahlgrenska University Hospital, and the Institute of Neuroscience and Physiology at the University of Gothenburg; all collaborating closely with the Biorobotics Institute of Scuola Superiore Sant’Anna in Italy.<br /><br />Read more about the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers:<br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />BNL website</a><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Chalmers BNL on Facebook</a><br /><br />Thu, 06 Apr 2017 07:00:00 +0200 a source for future antibiotics<p><b>​Fungi is a potential goldmine for the production of pharmaceuticals. This is shown by Chalmers researchers, who have developed a method for finding new antibiotics from nature’s own resources. The findings could prove very useful in the battle against antibiotic resistance.</b></p>​Antibiotics have saved millions of lives since they were discovered in the 1940s. But recently we’ve had to learn a new term; antibiotic resistance. More and more bacteria are developing their own protection against antibiotics, thereby becoming resistant to treatment. This will lead to simple infections getting lethal once again, and our need for new antibiotics is urgent.<br /><br />The first antibiotic being mass-produced was penicillin, derived from the Penicillium fungi. Looking for new antibiotics, Chalmers researchers sequenced the genomes of nine different types of Penicillium species. And the findings are amazing:<br /><br />– We found that the fungi has an enormous, previously untapped, potential for production of new antibiotics and other bio-active compounds, such as cancer medicines, says Jens Christian Nielsen, a PhD student at the Department of Biology and Biological Engineering.<br /><br />In the study, recently published in the journal Nature Microbiology, the research group scanned the genomes of 24 different kinds of fungi to find genes responsible for the production of different bio-active compounds, like antibiotics. More than 1000 pathways were discovered, showing an immense potential for fungi to produce a large variety of natural and bio-active chemicals that could be used as pharmaceuticals.<br /><br />In about 90 cases, the researchers were able to predict the chemical products of the pathways. As an evidence of this, they followed production of the antibiotic yanuthone, and identified a new version of the drug produced by species not previously known to produce it.<br /><br />All in all, the study show a vast potential for fungi, not only in producing new antibiotics but also in enabling a more efficient production of old ones – and maybe also more effective versions of the older ones.<br /><br />– It’s important to find new antibiotics in order to give physicians a broad palette of antibiotics, old as well as new, to use in treatment. This will make it harder for bacteria to develop resistance, Jens Christian Nielsen explains.<br />– Previous efforts on finding new antibiotics have mainly focused on bacteria. Fungi have been hard to study – we know very little of what they can do – but we do know that they develop bioactive substances naturally, as a way to protect themselves and survive in a competitive environment. This made it logical to apply our tools in research on fungi.<br /><br />Researchers now have different paths to follow. One way of moving forward would be to further look at production of the new yanuthone compound. The Chalmers researchers have also constructed a map making it possible to compare hundreds of genes in the continuous evaluation of bioactive products with potent drugs in sight.<br /><br />How long it would take to get new antibiotics on the market is impossible to say.<br /><br />– The governments need to act. The pharmaceutical industry don’t want to spend money on new antibiotics, it’s not lucrative. This is why our leaders have to step in and, for instance, support clinical studies. Their support would make it easier to reach the market, especially for smaller companies. This could fuel production, Jens Christian Nielsen says.<br /><br />Read the <a href="" target="_blank">full article here<span></span><span style="display:inline-block"></span></a>.<br /><br /><br />Text: Mia Malmstedt<br />Photo: Martina Butorac<br />Wed, 05 Apr 2017 14:00:00 +0200 world’s best university students use physics to tackle our everyday problems.aspx world’s best students use physics to tackle everyday problems<p><b>​How can you mix the honey in your tea in the most efficient way?

There will be teams from 15 countries and about 150 people will take part in the fights. The different challenges during the tournament include for example jelly Lego bricks, magnets, walking chains, toy cars, popcorn, tea and much more. <p>All together there are 17 tricky problems to be solved. The teams have had time to prepare since July 2016. After more than eight months the students have spent several hours of their spare time to work on the solutions. Learning by doing is the method and the problems do not have obvious solutions. </p> <p>“The idea with this competition is that the students work in the same way as a researcher. You need to figure out the essence of the problem, what you need to measure, how to do it and how to analyze the results. On top of that you must <span>also <span style="display:inline-block"></span></span>be able to present your solution in an understandable way and defend your conclusions. You need different skills to manage all this, that’s why it is so important with a good team work”, says Andreas Isacsson, one of the organizers and Professor at the Department of Physics at Chalmers University of Technology.</p> <p>This is the first time The Gothenburg Physics Centre hosts the competition, which takes place at Campus Johanneberg.

I am looking forward to meeting students from so many different countries, and to exchange ideas”, says Sanna Jarl, while working on the “Tea with honey” problem with the Chalmers team.</p> <p>During the tournament, every team will participate in four different fights. The teams that get the highest rating from the judges will meet in the finale. The final battle will be held in the Palmstedt lecture hall on Thursday 13 April at 9 am. </p> <p>Some of the teams from abroad have been working extremely hard to afford the trip to Sweden. For example, the students from Venezuela and Brazil organized crowdfunding campaigns to be able to participate in the tournament. </p> <p>“We are so happy that they managed! For me this is one of the best weeks of the year: so much curiosity, energy and motivation. And it’s interesting to see, that sometimes everyday phenomena which we take for granted, actually require rather complex physical reasoning if you wish to understand what is really going on”,  Andreas Isacsson.</p> <p>Both the qualifying fights and the final are open to the public and admission is free of charge. <br />The International Physicists’ Tournament 2017 is funded by Chalmers University of Technology and The Swedish Foundation for Strategic Research in collaboration with The Swedish Physical Society and other sponsors.

New theories within its domain continue to arise, creating new methods for solving as yet unproven problems. Due to the wealth of new ideas, existing fields of mathematical research have been divided into smaller branches, such as complex geometry, which is at the heart of the current project. Algebraic geometry studies sets consisting of solutions to polynomial equations. Such solution sets can take the form of circles, ellipses, spheres, and other geometric objects. For example, two points can be associated with a one-dimensional family of circles crossing both points. This is an example of a linear series, which is an important field of study in algebraic geometry.</p> <p>In the beginning of the 1990s, a Russian-American mathematician, Andrei Okounkov, introduced a way of associating each linear series with a convex body, called an Okounkov body. In 2006 he received the most prestigious award in mathematics, the Field’s medal, which is awarded to eminent mathematicians under forty years old. These convex Okounkov bodies have been successfully used to explain the properties of linear systems. The theory of linear systems is also connected to Kähler geometry, which is a meeting place for complex geometry, differential geometry, and symplectic geometry. It is assumed that the well-known and fundamental results regarding linear series can be generalized to a broader Kähler setting. Such generalizations would have significant consequences for Kähler geometry. Even though it remains to be seen which generalizations are possible, interesting open problems abound. </p> <p><strong><img class="chalmersPosition-FloatRight" alt="Dmitrii Zhelezov" src="/SiteCollectionImages/Institutioner/MV/Nyheter/DZ250x300.jpg" style="margin:5px" />Dmitrii Zhelezov</strong> will receive funding for a postdoctoral position at a foreign university and funding for two years after returning to Sweden. He will hold a postdoctoral position with Professor Endre Szemerédi at Alfréd Rényi Institute of Mathematics in Budapest, Hungary. Dmitrii Zhelezov received his Ph.D. in Mathematics from Chalmers University of Technology in 2016 with the thesis ”<a href="/en/departments/math/news/Pages/Addition-versus-multiplication.aspx">Additively and multiplicatively structured sets</a>” and was employed at the Department of Mathematical Sciences until August 2016.</p> <p>The aim of the project is to study arithmetic combinatorics, a branch of number theory. In contrast to other branches of mathematics, combinatorics focuses on specific problems, which are easy to formulate but notoriously difficult to solve, even when sometimes no mathematical apparatus beyond high school level is necessary for the solution. One of the most famous problems in number theory is the Goldbach conjecture, which states that every even integer greater than two can be expressed as a sum of two prime numbers. In 1742, German mathematician Christian Goldbach formulated the conjecture in a letter to a Swiss mathematician, Leonard Euler, by then already recognized as a genius. Euler’s response confirmed that he thought it was true but he couldn’t prove it. Nor has anyone else been able to do so, in the almost 300 years since. The difficulty in proving the conjecture stems from the fact that it refers to addition, whereas prime numbers are defined through multiplication – an integer is prime if it can be divided only by 1 and by itself. However, not much is known about how prime numbers should be linked to addition. </p> <p>A set of sums consists of the sums of all pairs of elements in a given set. The Goldbach conjecture asks whether the set of sums of prime numbers contains all even numbers greater than two. Initially, easy to handle questions about sets of sums can be studied. Subsequently, more advanced new tools and sophisticated methods, which had been developed for other problems, can be applied. Sets of sums have many other applications as well. The methods and concepts of abstract number theory have been successfully applied to modern cryptography. They are used to process our credit card payments as well as when we surf the internet.<br /><br /><strong>Text</strong>: from the press release of KWA<br /><strong>Photos</strong>: Setta Aspström</p>Fri, 24 Mar 2017 10:00:00 +0100 joins strong critique of bioenergy recommendations<p><b>Unsubstantiated claims and flawed arguments&quot;.

IEA Bioenergy, together with 125 scientists, strongly disagree with this recommendation, and urge Chatham House to reconsider their recommendations. “We invite Chatham House to engage in a more thoughtful and substantive discussion with technical experts like IEA Bioenergy and review the recommendations.
