Researchers at Chalmers University of Technology, Sweden, have developed a new material that prevents infections in wounds - a specially designed hydrogel, that works against all types of bacteria, including antibiotic-resistant ones. The new material offers great hope for combating a growing global problem.
The World Health Organization describes antibiotic-resistant bacteria as one of the greatest threats to global health. To deal with the problem, there needs to be a shift in the way we use antibiotics, and new, sustainable medical technologies must be developed.
Hydrogel wound dressing uses immune system proteins to kill bacteria
The technology is currently being commercialized by Chalmers spinoff company Amferia

It s no secret that the more we use antibiotics, the greater the chances that bacteria will develop a resistance to them. A new antibacterial wound dressing is designed to get around that problem, by using proteins instead of conventional antibiotics.
The experimental hydrogel skin patch is being developed at Sweden s Chalmers University of Technology, by a team led by Prof. Martin Andersson.
It contains antimicrobial peptides, which are proteins that occur naturally in our immune system. Because their destructive effect on bacteria is limited to compromising the microbes protective outer membrane, the scientists believe that bacteria are unlikely to develop a resistance to the peptides. What s more, lab tests have shown the gel to be highly effective at killing harmful ba

AstaZero is opening a 700m long and 40m wide indoor track in Sweden for testing active safety systems and autonomous vehicle (AV) technologies.
The autonomous transport test facility is owned by Rise (Research Institutes of Sweden) and Chalmers University of Technology.
The Asta Zero Dry Zone has received SEK 10 million from the Västra Götaland Region s sustainable transport programme.
AstaZero CEO Peter Janevik says: “The tests and trials conducted by vehicle operators require plenty of personnel and result in excessive travel. In AstaZero Dry Zone, the development time can be streamlined and tests can be carried out 24 hours a day, 365 days a year.”

The conditions and technology for production in space are developing rapidly. Recently, NASA made a breakthrough when they managed to extract oxygen from carbon dioxide on the surface of Mars. At Chalmers University of Technology and Onsala Space Observatory, Sweden, there are lots of ongoing research activities related to production in space.
Tomorrow is International Star Wars Day, and Chalmers is hosting a seminar, with a focus on – appropriately enough – production in space.

April 29, 2021, Mountain View, CA - The SETI Institute announced today the 2020 and 2021 recipients of the SETI Forward award, recognizing outstanding undergraduate interns studying astrobiology and SETI research: Karen Isabel Perez - Columbia University, Ellie White - Marshall University and Siddhant Sharma - University of Delhi. The SETI Forward award provides scholarship funds to support the next generation of scientists pursuing SETI and astrobiology career opportunities and connects promising students with researchers. All three recipients will receive their awards at the 2021 Drake Awards ceremony taking place on May 6, 2021. We are delighted to recognize Karen, Ellie and Siddhant for their achievements as summer interns in astrobiology and SETI research programs, said Bill Diamond, President and CEO of the SETI Institute. Providing undergraduates with the opportunity to not only do compelling science but also explore and discover career opportunit
