During WWII, doctors noticed severely injured soldiers didn't need pain medication. Biomedical researchers have known for some time that the brain has an endogenous opiate system that controls pain. Now, they've found evidence of a new pain relief circuit.

Scientists are carefully monitoring the west Antarctic ice sheet. It's melting, and has been responsible for about four percent of the global rise in sea levels to date.

An illness all by itself is unpleasant, but the isolation we experience while recovering is also bad for our health. There's research showing that social isolation is associated with increased inflammation in the body.

Reindeer herds may be saving thawing permafrost, which can release greenhouse gases stored in it and speed up climate change.

When you stub your toe or hit your head, sometimes a swear word will slip out. Some researchers argue that this is a kind of stress-reduced analgesia, or pain-reliever.

Every summer, scores of trained volunteers scan coastal beaches, looking for sea turtle nests. When found, the nests are marked and watched, preventing predators or curious humans from finding the eggs.

It's interesting that modern anthropologists can do more than just study fossil bones and teeth. Ancient remains sometimes contain surviving DNA, and this has let scientists study the genomes of both the Neanderthals and the Denisovans.

Have you ever wondered how bugs handle being upside down for so long? It's a puzzling question, especially since insects don't have a closed circulatory system like we humans do.

Over the next few decades, bread may become an important protein source for many consumers, and animal protein alone won’t be able to meet the demand. Right now, researchers are engineering a new kind of flour for bread making, a flour that is made from insects.

According to a study published by American researchers in 2020, unless we change current practices, by the end of this century there will be more than twice as much carbon dioxide in the atmosphere as there was before the industrial revolution.
