Atlas identifies genome regions that regulate plant cell identity

Zoom in on the leaf of a corn plant, and you’ll find a patchwork of about 20 different cell types. A recent study, published in Cell, provides an atlas of critical genomic regions that control cell identity in six different … Continue reading

Transgenic switchgrass cleans up contamination from military explosives

At military sites in the United States and across the globe, routine live-fire trainings produce a downpour of an explosive known as RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine). A synthetic chemical, RDX can threaten human health, damaging the nervous system if inhaled or ingested. … Continue reading

Gossip drives social bonding and helps people learn

Oscar Wilde said the only thing worse than being talked about was not being talked about. Nevertheless, chit-chat about others has a dubious reputation. That’s unfair, say psychologists and social scientists, who argue that gossip is a useful communication tool, … Continue reading

Several brain regions help us anticipate what’s going to happen next

If you watch a movie clip on repeat, many areas of your brain begin to anticipate upcoming events onscreen, according to a recent study published in eLife. The first time you see the clip, your brain forms a distinctive neural … Continue reading

Heavy water tastes sweeter

In the 1930s, scientists discovered a heavier form of water. So-called “heavy water” (D2O) weighs more because the nucleus of each of its two hydrogen atoms contains not just a proton but a neutron as well. Known as deuterium, heavy … Continue reading

Small, sharp blades mark the change from Middle to Later Stone Age in coastal Kenya

The transition between the Middle and Later Stone Age is a controversial topic among archeologists. Recent findings offer a possible answer, suggesting that the shift occurred between 67,000 and 71,000 years ago, and has as its hallmark a sudden abundance … Continue reading

Venus flytrap mechanism could shed light on how plants sense touch

Labelled by Charles Darwin as a “most wonderful” plant, the Venus flytrap is more than a carnivorous curiosity. The rapid closing of its leaves when brushed by prey offers researchers a way to investigate how plants sense their environment through … Continue reading

Lab-cultured mouse embryos, grown for an extended period, offer a new window on fetal development

In a potential methods breakthrough, stem cell biologists grew mouse embryos for five-and-a-half days in vitro, longer than ever before. Appearing recently in Nature, the study unveils new protocols and equipment, including a temperature-and-pressure-controlled incubator that enabled the coauthors to … Continue reading

Massive study suggests chimp populations mixed more recently than previously reported

A recent study in Communications Biology reports results from the largest such survey of chimpanzee genetics so far. It suggests that animals from the different groups have mixed more recently than many researchers in the field previously believed. The findings … Continue reading

Agricultural spray could quickly deliver advantageous genes to crops mid-growing season

Plant breeders are masters of genome tuning, spending years developing crops with the genes to resist disease, drought, and pests. Now, a team of industry and academic researchers in Germany and the United Kingdom has developed a viral vector technology … Continue reading

Mutations in metabolic genes can cause antibiotic resistance

A recent study in Science reveals a novel avenue by which genetic changes make bacteria resistant to drugs: mutations in genes involved in cellular metabolism, including some that convert food into energy. “The genes were known; their involvement in metabolism … Continue reading
