    What happens to animals in a hurricane?

    After hammering the Bahamas, Hurricane Joaquin is now moving north, and, the latest path predictions show, is headed out to sea instead of directly for the U.S. East Coast. The storm’s track has been hard to pin down, which makes preparing for it rather difficult. If you live near the shore, you don’t know if...

    Ceres mountains and craters named for food

    Tubers, maize and even eggplants are finally getting the astronomical recognition they deserve. Or at least that’s true for the deities that look after the crops and celebrations of their harvest. Fifteen craters and mountains on the dwarf planet Ceres were officially named on September 21 after various spirits and celebrations...

    Lights at night trick wild wallabies into breeding late

    Artificial lighting at night delays wild tammar wallaby breeding, potentially pushing the nursing marsupial moms out of sync with their peak season for food.

    Tammar wallabies (Macropus eugenii) that live on the well-lit landscape of Australia’s largest naval base muddle the timing of their natural breeding season. Births peak in February — a month later on average than normal —...

    Math describes sheep herd fluctuations

    View the video

    There’s something in the way sheep move.

    In a herd, Merino sheep follow a predictable pattern of spreading out and clustering together. Now scientists have developed equations that can describe those movements. The sheep’s choreography may allow them to balance their needs for food and protection,...

    Life in the polar ocean is surprisingly active in the dark winter

    Scientists have long thought that in the supercold, perpetually dark, polar winter, life pretty much shuts down. With no sunlight, there’s no photosynthesis, so phytoplankton wouldn’t be active. That would cut off the base of the marine food web, and there would be no energy entering the system. Everything else would have to enter a resting state, the theories suggested. That would include...

    How a fat hormone might make us born to run

    Last weekend, I ran the Navy-Air Force half-marathon. After pounding pavement for an hour or so, my legs began to feel light. Slightly numb. I felt fantastic. I had to remind myself to run, not to stop and dance, and that singing along to my candy-pop workout music — even at mile 10 — is not socially acceptable. It’s the hope of this euphoria — this runner’s high — that keeps me running.

    For people, mealtime is all the time

    Three meals a day is a myth. People eat all the time, a new study shows.

    People eat almost constantly for about 15 hours a day, nearly all of their waking hours, researchers learned from studying smartphone pictures that people took of food. Restricting eating time to a 10-hour stretch per day led to weight loss in a small group...

    More than 9,000-year-old decapitated head discovered in Brazil

    A human skull found in a Brazilian rock-shelter represents the oldest known case of decapitation in the Americas, researchers report September 23 in PLOS ONE.

    Radiocarbon dating places the skull at between 9,127 and 9,438 years old, says a team led by André Strauss of the Max Planck Institute for Evolutionary...

    'The Martian' is entertaining science fiction rooted in fact

    Watch the trailer

    Scientists are used to suspending disbelief when they go to movies. But The Martian, opening October 2, offers a mostly realistic view of conditions astronauts might encounter on Mars.

    The movie “is a vision of a future we can step into and make happen,” says Jim Green,...

    A parting shot of coffee

    Two decades of medical writing induces a certain skepticism toward research. You just can’t go all gaga over every study that crosses your desk. But I confess to being intrigued by a recent report...
