In mammals—including us humans—sperm are surprisingly picky about temperature, thriving best in conditions a few degrees cooler than normal body temperature. But, given that the female reproductive tract is warmer than normal body temperature, how do thes

Marine habitats are facing unprecedented threats, with 66% of coastal areas already altered and degraded. Bottom-contact fisheries, which use indiscriminate trawling, physically damage almost 5 million square kilometers of the seafloor each year.

Before they can fight to survive, some endangered songbirds are losing their groove and being robbed of their chance at love—all because of what's in their food.

Results from a long-term field experiment shed new light on how grasslands can be restored for nature, the environment, and for farmers.

Relief may be in sight for kākāpō affected by an extremely painful disease, thanks to a University of Otago—Ōtākou Whakaihu Waka-led study.

Looking around, you might not realize it, but corn is everywhere. In one form or another, it's in the cereals in your cupboard, the cosmetics and medicines in your bathroom, the kibble in your pet's food bowl, and the gas tank of your car.

Just a few weeks after conception, stem cells are already orchestrating the future structure of the human brain. A new Yale-led study shows that, early in development, molecular "traffic cops" known as morphogens regulate the activation of gene

Texas A&M AgriLife Research scientists have developed a new approach to countering citrus greening and potato zebra chip diseases, two economically devastating agricultural diseases in the U.S.

A study published in Science reveals that North American bird populations are declining most severely in areas where they should be thriving. Researchers from the Cornell Lab of Ornithology analyzed 36 million bird observations shared by birdwatchers to t

A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen.

For billions of years, viruses and bacteria have been embroiled in an arms race. In response to constant attacks by viruses known as bacteriophages—more commonly called "phages"—bacteria evolve new ways to defend themselves. And, in turn, phages

Imagine trying to tell identical twins apart just by looking at their fingerprints. That's how challenging it can be for scientists to distinguish the tiny powdery pollen grains produced by fir, spruce and pine trees.
