Losos honored by American Society of Naturalists
The American Society of Naturalists has recognized Jonathan B. Losos, the William H. Danforth Distinguished University Professor at Washington University and director of the Living Earth Collaborative, with its 2019 Sewall Wright Award.
Takes a licking and keeps on storing
Researchers in Arts & Sciences made an energy storage device that can withstand a hammer striking it more than 40 times. The shatterproof supercapacitor is also nonflammable, unlike lithium-ion batteries. The new work is the cover story of the April 23 issue of the journal Sustainable Energy and Fuels.
The kids are alright
A new study reveals the surprising way that family quarrels in seeds drive rapid evolution. Conflict over resources seems to play a special role in the development of certain seed tissues, according to Washington University in St. Louis research led by David Queller and Joan Strassmann in Arts & Sciences.
The global helium shortage hits home
Helium is a valuable, non-renewable resource that is critical for many medical and research applications. But helium supply and pricing are unreliable. Sophia Hayes, a professor of chemistry in Arts & Sciences, spoke at a recent American Chemical Society webinar about the need for congressional action to address these challenges.
Creating sustainable bioplastics from electricity-eating microbes
Researchers in Arts & Sciences at Washington University in St. Louis have figured out how to feed electricity to microbes to grow truly green, biodegradable plastic, as reported in the Journal of Industrial Microbiology and Biotechnology.
Specialist enzymes make E. coli antibiotic resistant at low pH
New research from Arts & Sciences suggests that many “redundant” enzymes are actually specialists that ensure maximal growth across different environments. They also seem to increase resistance to antibiotics in conditions like those in the GI tract or urinary tract — raising concerns that current antibiotic susceptibility tests are inadequate.
Tidying up: A new way to direct trash to autophagy
Marie Kondo herself couldn’t do it any better. Now researchers at Washington University in St. Louis have uncovered a previously unknown structural feature of living cells that is critical to tidying up.
Rusted root: Weedy rice repeatedly evolves ‘cheater’ root traits
Researchers led by Kenneth M. Olsen in Arts & Sciences used a new imaging technique to reveal a takeover strategy that has worked for weedy rice over and over again: roots that minimize below-ground contact with other plants.
‘Featherweight oxygen’ discovery opens window on nuclear symmetry
Researchers in Arts & Sciences have discovered and characterized a new form of oxygen dubbed “featherweight oxygen” — the lightest-ever version of the familiar chemical element oxygen, with only three neutrons to its eight protons.
How electricity-eating microbes use electrons to fix carbon dioxide
Led by Arpita Bose, assistant professor of biology in Arts & Sciences, a Washington University team showed how an electricity-eating microbe takes up electrons from conductive substances like metal oxides or rust to reduce carbon dioxide. The work is described in the journal Nature Communications.
