Evidence piles up for popular pesticides’ link to pollinator problems

The link between pollinator problems and neonicotinoids, a group of agricultural pesticides commonly associated with declines in honeybees, continues to build with two new studies published this week. Butterflies of Northern California join the ranks of honeybees, bumblebees, moths and other organisms that may be feeling the effects of the infamous insecticides. Butterfly species in […]

Tasmanian devils evolve resistance to contagious cancer

A few Tasmanian devils have started a resistance movement against a contagious cancer that has depleted their numbers. Since devil facial tumor disease was first discovered in 1996, it has wiped out about 80 percent of the Tasmanian devil population. In some places, up to 95 percent of devils (Sarcophilus harrisii) have succumbed to facial […]

California’s goby is actually two different fish

It’s official: The southern tidewater goby is a thing. And it’s chubbier and nubbier than its northern cousin. Endangered tidewater gobies live in California’s seaside lagoons. Ranging roughly the entire length of the state, the fish used to be considered one species. But a new study confirms that gobies living in Northern and Southern California […]

Brain’s physical structure may help guide its wiring

In growing brains, billions of nerve cells must make trillions of precise connections. As they snake through the brain, nerve cell tendrils called axons use the brain’s stiffness to guide them on their challenging journey, a study of frog nerve cells suggests. The results, described online September 19 in Nature Neuroscience, show that along with […]

Jeremy Freeman seeks to simplify complex brain science

Jeremy Freeman loves clean, simple lines. To see his bent toward aesthetic minimalism, you need look no further than his spare, calm website that slowly shifts colors. In the past, this fixation with style has occasionally veered toward the extreme. In graduate school at New York University, “he decided that capital letters were ugly,” says […]

Europa spouting off again

Jupiter’s moon Europa might once again be venting water into space, further supporting the idea that an ocean hides beneath its thick shell of ice, researchers reported September 26 at a news conference. Plumes erupting from the moon’s surface, silhouetted against background light from Jupiter, appear in several images taken by the Hubble Space Telescope […]

Eels may not take most direct route in epic ocean-crossing spawning runs

Storied spawning runs of European eels may not be an en masse push to a mating site. Roundabout routes may delay many eels so much that they miss the big event and have to wait to mate until next season. The most extensive reconstructions of individual eel journeys challenge an assumption that Europe’s freshwater eels […]

First peek under clouds reveals Jupiter’s surprising depths

PASADENA, Calif. — Jupiter’s clouds have deep roots. The multicolored bands that wrap around the planet reach hundreds of kilometers down into the atmosphere, NASA’s Juno spacecraft reveals, providing an unprecedented peek into the giant planet’s interior. “Whatever’s making those colors and stripes still exists pretty far down,” planetary scientist Scott Bolton, head of the […]

Dragon dinosaur met a muddy end

A bizarre new birdlike dino was part of an evolutionary extravaganza at the end of the age of dinosaurs. And it was a real stick-in-the-mud, too. Construction workers blasted Tongtianlong limosus out of the Earth near Ganzhou in southern China. “They very nearly blew this thing to smithereens,” says paleontologist Stephen Brusatte of the University […]

Skimpy sea ice linked to reindeer starvation on land

Unseasonable shrinking of sea ice could trigger another peril of climate change: increasing ice-overs on land that starve reindeer and threaten Siberian herders’ way of life. The worst of these events in the memory of Nenets herders on Russia’s Yamal Peninsula killed 61,000 of 275,000 reindeer in 2013, a blow to the herders’ livelihood that […]
