Instead of destroying its leafy hosts, one common plant virus takes a more backhanded approach to domination. It makes infected plants more attractive to pollinators, ensuring itself a continued supply of virus-susceptible plant hosts for generations to come. The strategy might be a way for the virus to discourage resistance from building up in the […]
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 […]
Sex matters when it comes to cornea transplants — at least for women. Corneas are low on the list of organs that cause rejection, but it happens more often when women receive corneas from men, researchers report online July 22 in the American Journal of Transplantation. In data from nearly 17,000 transplants, 220 of every […]
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 […]
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 […]
President Barack Obama’s “Cancer Moonshot” now has a scientific flight plan. It calls for better cooperation among researchers and institutions, aggressive pursuit of immunotherapy and making better use of proven cancer prevention strategies. Called the Blue Ribbon Panel Report, the document was approved September 7 by the National Cancer Advisory Board, part of the National […]
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 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 […]
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 […]
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 […]
