They say youth is wasted on the young, but when it comes to pleasure chemicals in our brains, the opposite may be true. A study released today shows that there is a drastic change in how our brains respond to pleasure and reward as we age.

Researchers are finding that rising levels of carbon dioxide in the air might be bad for our gardens and food prices, even though plants need CO2 to breathe. Research is showing that too much CO2 can make at least one major crop more vulnerable to pests.

The big knock on wind turbines has been that they’re dangerous to birds. But researchers have found that they actually kill more bats, and the reason why has been a mystery–until now.

Doctors are considering using a new technology to genetically modify AIDS patients’ own cells to be resistant to HIV.

Scientists are one step closer to knowing the true colors of some dinosaurs. This ScienCentral News video describes how Yale researchers found a clue to colors in bird feather fossils.

Is that tumor cancerous, and how fast might it spread? Pathologists have to answer those tricky questions every day. But, as this ScienCentral News video explains, research published today puts a tool normally found in crime labs into the hands of doctors so they can do a better job of catching cancer.

The holy grail of cancer detection is a simple blood test that would spot signals of cancer early enough to cure it. Now genetics researchers report a surprising discovery that could lead to such tests.

It may be the closest known thing to a cure for type 2 diabetes: gastric bypass surgery, currently done only for major weight loss. But one surgeon hopes to prove that a similar surgery could help non-obese diabetics. Meet a diabetes patient who’s determined to have the surgery.

Using carbon dioxide as an ingredient in plastics could help reduce the use of fossil fuels, and be another market for waste CO2. A Cornell chemist has started up a company that’s now making plastics containing up to 50 percent CO2.

Genetics researchers have debunked a racial myth about who might benefit from a widely used heart failure medication. The finding will eventually allow personalized treatments for this devastating disease.
