A new study by Yves Brun has revealed that some bacteria living in biofilms has the ability to sacrifice themselves when the environment inside the biofilm declines, thus ensuring the survival of the community.

Researchers have used a compound derived from β-carotene, a molecular structure of carotenoids, found in carrots, for developing a degradable polymer. A 10-carbon dialdehyde; and p-phenylenediamines, a group of compounds used in degradable polymers, were also used to make three different poly(azomethine)s which ranged in color from black to bright red on drying.

The Super Steel project led by Professor Huang Mingxin from the Department of Mechanical Engineering, University of Hong Kong (HKU) along with collaborators at the Lawrence Berkeley National Lab (LBNL) have made an important breakthrough in its new super D&P steel (produced using a new deformed and partitioned method) to greatly enhance its fracture resistance while maintaining super strong in strength for advanced industrial applications.

PEC can convert sunlight into fuels, but often has stability problems. A team from Uni Hamburg, Desy & LMU developed a setup in the BMBF project Lucent to analyze changes of PEC materials in all length scales.

Scent dogs may represent a cheaper, faster and more effective way to detect Covid-19, and could be a key tool in future pandemics, a new review of recent research suggests. The review, published in De Gruyter’s Journal of Osteopathic Medicine, found that scent dogs are as effective, or even more effective, than conventional Covid-19 tests such as RT-PCR.

As food costs continue to rise and a global food crisis looms on the horizon, it’s staggering to think that some 30-40 percent of America’s food supply ends up in landfills, mostly due to spoilage. At the same time, the World Health Organization estimates that foodborne illness from microbial contamination causes about 420,000 deaths per year worldwide.

Turning unused waste from food production into clean energy: Researchers at ETH Zurich and Nanyang Technological University Singapore are using chicken feathers to make fuel cells more cost-effective and sustainable.

Researchers have been able to get a better understanding into how global warming might affect methane which is produced in Arctic lakes by studying the waxy coatings of leaves that have been preserved in the fossils from ancient aquatic plants.

Wearable devices such as smart watches could be used to detect a higher risk of developing heart failure and irregular heart rhythms in later life, suggests a new study led by UCL researchers.

Small sulfate particles of diameters 0.4 µm or less from anthropogenic sources could have had a cooling effect on the climate in the 1970s, by triggering cloud formation and reflection radiation.
