Brain cells in older Drosophila tend to have more than two complete sets of chromosomes, and that polyploidy most likely has a protective function, a study shows.
Weill Cornell Medicine geneticist Christopher Mason speaks with The Scientist about a bolus of new work on the physiological, cellular, and molecular effects of leaving Earth.
An abundance of immunoglobulin antibodies, and a paucity of viral RNA, in breastmilk offer evidence that women can safely continue breastfeeding during the pandemic.
Mechanically sensitive proteins called gellins sense and respond to protoplasm flowing out of severed hyphae, quickly sealing up injuries in these root-like structures of fungi.
Enhancers, short regions of DNA that direct gene expression, of species separated by 700 million years of evolution worked interchangeably, according to a new study.
SARS-CoV-2, the virus that causes COVID-19, taps into human proteases such as furin to enter cells. Temporarily inhibiting those enzymes might stymie infection.
Genetically engineered cells that overproduce ACE2, the receptor the novel coronavirus uses to enter cells, neutralize infection in vitro and mop up inflammatory cytokines in mice.
