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

Unlocking a mystery of seed development promises fatter, oilier oilseeds
The canola cooking oil lining supermarket shelves comes from the seeds of Brassica napus, a weedy-looking plant in the mustard family. Farmers of this crop understandably want varieties that yield big, oily seeds. A recent study in The Plant Cell … 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

Sweeping study finds big landscape changes on the fringes of Europe’s protected areas
Quaint cobblestone towns and green pastures dot the Pyrenees Mountains, at the gates of Catalonia’s Aigüestortes i Estany de Sant Maurici National Park. Hike a few miles into the park, though, and the Spanish landscape of trickling rivers and montane … 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
