The chemical that puts the heat in hot chili peppers is capsaicin (kap-SAY-ih-sin). Yet scientists have known for some time that when applied to the skin, this same compound can diminish pain. Indeed, some over-the-counter pain relievers already rely on capsaicin to tackle sore muscles and joints. But how that chili chemical chilled sore nerves has remained somewhat of a mystery.

That’s what researchers in China and Michigan reported February 16 in Current Biology. Still unclear, they say, is whether the birds might sense salty and sour flavors. So while these birds can down big meals of fish, they...

Blood-brain barrier (noun, “blood bray-n bare-ee-er”)A layer of cells between the blood vessels and the cells of our brains. The brain is very delicate and can’t be exposed to just anything in the blood. This barrier of cells lets oxygen and nutrients in. But it keeps out foreign substances, such as dangerous bacteria. The barrier is important, but it can also be difficult to deal with. When...

Cosmetics commercials extoll the virtues of long, luxurious eyelashes. They even sell products to make them longer. But, new research indicates, in terms of eye health, long isn’t always better.There’s a so-called “sweet spot” in the range of lash lengths. It is about one-third the width of the eye. And it’s here that lash length appears most helpful. Eyelashes much longer than that will funnel...

For the first time, scientists have shown a direct link between rising levels of carbon dioxide — or CO2 — in Earth’s atmosphere and an increase in how much solar energy warms the ground. The finding supports a key theory about what’s behind the recent worldwide warming of Earth’s climate. It links a measurable share of that warming to human activities that release CO2. These include the burning...

Zorana Berberovic gently lifts a small black mouse by its tail. As its hind legs rise up off the floor of its cage, the research technician slips a tiny vial under the mouse’s bottom. Berberovic lightly strokes her gloved finger against its belly. Within seconds, she is rewarded. A dribble of pee enters the vial."They have small bladders so there's not much," Berberovic says. Luckily, she adds, "...
