- Eating red meat can increase the risk of certain types of cancer. But scientists have discovered that eating potatoes and other foods containing 'resistant' starch can help limit those risks.
- A number of diseases threaten the world’s most popular fruit. Scientists are working to fight these blights. But if they don’t succeed, the sweet banana that’s a breakfast staple could disappear.
- Scientists find that boys’ and girls’ versions of lacrosse lead to similar injuries. Because girls frequently get concussions, the study argues that like the boys, girls too should wear helmets.
- Certain types of fiber suppress appetite, at least in mice. Found in fruits, vegetables, oats and barley, this fiber breaks down in the gut to release acetate. That travels to the brain, where the chemical prompts the release of hunger-fighting hormones.
- Germs can hitchhike into the kitchen on meat and many types of produce. A new study finds that some of those germs are particularly nasty. They are immune to the one or more of the drugs doctors would prescribe to wipe out the infection.
- Population density can determine how much of an impact modern communities have on the climate.
- The American Academy of Pediatrics suggests taking steps to limit children’s exposure to pesticides.
- Scientists find evidence that pesticides, disease and other threats are devastating bees. And that could hurt farmers big time.
- Scientists observe some evolutionary speed demons as they adapt over the course of just a few years to new environmental conditions.
