Mouse gut bacteria cure rotavirus infection, pointing to treatment for humans

Despite available vaccines, over 200,000 children die annually from severe diarrhea cause by rotavirus, which infects intestinal cells. A recently published study, facilitated by a research team’s lucky break, suggests bacteria in the mouse gut microbiome could actually help prevent … Continue reading

Hydrogel uses biology and light to release proteins on demand, advancing hopes for synthetic tissues

A wiggly cylinder of protein, hydrogel, and human cells, about the size of a wristwatch battery, could one day serve as a building block for synthetic tissues. The implications could be big for biological research and even organ transplants, according … Continue reading

Common features of domestic animals suggest caveats to evolutionary theory

White patches on fur coats, floppy ears, and curly tails are some of the traits frequently seen in domesticated animals. A group of researchers has now put forth a theory as to why these traits so often evolve in association … Continue reading

For choices involving uncertainty, the brain simplifies the math that drives our decisions

Every day, people make countless decisions, big and small: Should I buy that new house? Do I want chocolate or vanilla ice cream? A recent study suggests that when faced with uncertainty regarding a choice, how a person evaluates their … Continue reading

Smarter birds speciate faster

Evolution favors brainier birds. The most crowded branches of the avian tree of life generally hold the most intelligent birds because larger-brained birds split into new species faster than smaller-brained ones, according to recent work published in Evolution. “Being smart … Continue reading

New insights into how influenza evades human immunity

Some viruses can only infect people once—measles for example. But other viruses, notably influenza, are capable of infecting repeatedly. Scientists have long puzzled over how the flu virus evades human immunity. Recent work in eLife clarifies exactly how the virus … Continue reading

Pollen frozen in a glacier reveals the legacy of human impacts in the heart of the Inca Empire

The Illimani glacier sits between the urban sprawl of La Paz, Bolivia, on one side, and the roads and plantations of the Amazon basin on the other. It was no doubt a very different landscape some 550 years ago, when … Continue reading

Nitrogen-fixing bacteria talk to soybean roots via tiny RNAs, suggesting new avenue to improve yields

In order for soybean plants to get their necessary dose of nitrogen, they partner with bacteria called rhizobia, which can convert atmospheric nitrogen into organic forms the plant can use. But scientists don’t have the full picture of what facilitates … Continue reading

By separating life stages, metamorphosis may circumvent harmful evolutionary tradeoffs

  There’s no guarantee evolution will bestow the best version of every trait. The benefits of one trait may impose a cost when an unfavorable trait, correlated genetically, comes along for the ride. In a recent study on wood frogs (Rana sylvatica) … Continue reading
