A trio of biologists at the University of Colorado has found that dragonflies that cover themselves in a waxy coating fare better as the climate grows warmer and drier in regions where they live. In their study‚ published in the Proceedings of the National Academy of Sciences‚ Michael Moore‚ Sarah Nalley and Dalal Hamadah tested the impact of pruinescence in two ways with dragonflies living in dry parts of North America.

The toxin candidalysin of the yeast Candida albicans is incorporated into an unusual protein structure during an infection‚ the composition of which has so far been unknown to scientists. Researchers at the Leibniz-HKI have now succeeded in deciphering the function of this unusual arrangement.

A trio of researchers‚ one a sociologist at Princeton University‚ the other two public policy experts with the University of Michigan‚ has found that children living in Flint‚ Michigan‚ experienced educational declines after that city changed its water delivery system in 2015‚ regardless of whether they lived in homes with lead pipe delivery systems.

Pseudomonas aeruginosa is an important opportunistic pathogen responsible for life-threatening infections that are associated with high rates of morbidity and mortality. Researchers from TWINCORE‚ the Center for Experimental and Clinical Infection Research in Hannover‚ and the Helmholtz Center for Infection Research (HZI) in Braunschweig have now been able to show that an enzyme controls virulence through modification of tRNAs. They hope that their findings will pave the way for the development of new treatments.

The Human Genome Project generated the first sequence of the human genome‚ revealing a kind of blueprint of human biology. Two decades later‚ the field of gene regulatory networks describes a complex system where thousands of genes regulate one another to create appropriate gene expression dynamics.

With global goals set on transitioning away from fossil fuels‚ fuel cells stand out as a promising carbon-free energy source. Comprising an anode and a cathode separated by an electrolyte‚ fuel cells convert the chemical energy of fuel directly into electricity. The anode receives the fuel‚ while an oxidant‚ typically oxygen from the air‚ is introduced at the cathode.

When it comes to nurturing their young‚ mother chimpanzees go the extra mile‚ according to a new study. Using 10 years of observational data on wild chimpanzees‚ researchers found that while adults often play‚ and young chimps play a lot‚ when food gets scarce‚ the adults put mutual play aside and focus on survival.

After the egg has been fertilized by a sperm‚ the surrounding egg coat tightens‚ mechanically preventing the entry of additional sperm and the ensuing death of the embryo. This is according to a new study led by researchers at Karolinska Institutet and published in the journal Cell. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods.

Scientists at the UK Dementia Research Institute at King's at the Institute of Psychiatry‚ Psychology &; Neuroscience have developed a process enabling custom cell culture device creation. This pipeline has been published in PLOS Biology and is available as an open source on GitHub.

Adults ages 60 and up in developed nations are spending more money on energy than younger counterparts—and are also more likely to struggle to reduce those higher costs‚ according to research led in part by University of Maryland geographers.
