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

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

In Mesopotamia, early cities may have faltered before climate-driven collapse

Some of the earliest cities, now buried in the soil of Syria, Iraq, Turkey, and Lebanon, are thought to have collapsed because of rapid climatic change. Drought along with lower temperatures descended on these settlements some 4,200 years ago, forcing … Continue reading

Host defenses signal Salmonella to hijack immune cells, spur disease

Immune cells attack dangerous bacteria by engulfing them and then releasing a cascade of defense molecules. But some bacteria, known as intracellular pathogens, have evolved to survive this onslaught and replicate inside immune cells. The result can be Salmonella poisoning … Continue reading

To predict the success of tree-planting schemes, look to villagers’ involvement

Tree-planting projects are sprouting up worldwide in an effort to sequester carbon. Acres of saplings are quick to plant but don’t necessarily have staying power: many die or are cut down before the trees grow to maturity. A recent study … Continue reading

Study reveals evolutionary origins of fold-switching protein

Most proteins are thought to fold into a single active shape. But the human immune protein XCL1 is a rare breed that can switch back and forth between two different structures, each with its own function. A recent study in … Continue reading
