Pollen tainted with neonicotinoid pesticides could interfere with male honeybee reproduction, a new study finds.
After bee colonies fed on pollen spiked with the pesticides thiamethoxam and clothianidin, male bees, or drones, produced almost 40 percent fewer living sperm than did males from colonies...
As happens every summer, sea ice in the Arctic is shrinking as temperatures warm. But this year is a particularly warm year, and there is less sea ice than there usually is. Scientists say Earth is on track to matchor perhaps even exceed the record low extent of summertime sea ice seen in...
How can aging be delayed? How does the brain age? And what does aging look like in animals, plants or the rest of the natural world? The July 23 issue of Science News tackles these questions and more in a special report called "Aging's Future."
On Tuesday, July 26, at 3 p.m. EDT, three Science News reporters...
Clones don’t age prematurely, new research on Dolly the Sheep’s sisters suggests.
Researchers and animal welfare activists have been concerned that cloning, or somatic cell nuclear transfer, could cause health problems in cloned animals. Instead, a study of 13 cloned sheep found no signs of early aging or other health...
Here’s another reason to show up with a box of chocolates: It doubles as a shield if she bites.
Edging slowly toward a female, male nursery web spiders clutch in front of their bodies their version of courtship candy: a big dead insect wrapped in white silk. “It’s pretty spectacular actually,” says Søren Toft of Denmark’s Aarhus University. It’s also prudent, he and colleague Maria Albo...
As the saying goes, “It’s difficult to make predictions, especially about the future.” The website Metaculus.com aims to make this challenging task easier by harnessing collective wisdom.
Metaculus solicits answers to questions about the future — on topics spanning science, politics and economics — and combines these predictions to infer the likely...
In the space business, weight and size are what run up the bills. So imagine the appeal of a telescope that’s a tenth to as little as a hundredth as heavy, bulky and power hungry as the conventional instruments that NASA and other government agencies now send into space. Especially alluring is the notion of marrying the time-tested technology called interferometry, used in traditional...
Whiffs of ancient air trapped in rock salt for hundreds of millions of years are shaking up the history of oxygen and life on Earth.
By carefully crushing rock salt, researchers have measured the chemical makeup of air pockets embedded inside the rock. This new technique reveals that oxygen made up 10.9 percent of Earth’s atmosphere around 815 million years ago. Scientists have thought...

In the arms race of life, a number of animals use venom as a weapon to paralyze prey and jump-start digestion. Meanwhile, venom also helps a variety of other seemingly defenseless creatures improve their odds against larger, stronger or more aggressive foes.
In Venomous, molecular biologist Christie Wilcox surveys the animal kingdom’s wide array of biochemical warriors, from...
After two years of renovations, some of the museum’s most cherished artifacts — including the Spirit of St. Louis and an Apollo Lunar Module — are now on display alongside new objects, including a studio model of the Starship Enterprise.
