It turns out donated blood has a shelf life – and it can be very different for each donor. Recently, scientists have found a way to track how blood ages, helping hospitals manage their supply more effectively.

For some time, we've known that it's rare to see people with both cancer and Alzheimer's diseases. Now, scientists believe they may have found why, discovering a molecule in cancer cells that clears problem proteins from the brain.

Don’t remember if you took your pills? Try MIT’s SAFARI (Smart Adherence via FARaday cage And Resorbable Ingestible). The capsule has its own bioresorbable radio that activates itself when swallowed, so you’ll never worry about missing a dosage.

Forget strips, gels, and pastes. Your next tooth-whitening and repairing substance might well be a new powder developed by Shanghai researchers. You'll want to use it with an electric toothbrush though, because that's what makes it spark.

If you want a really good workout, you shouldn't just be sitting around. That's at least part of the thinking behind the Martoni Cardio Speeder, a seatless exercise bike that puts the user in what its creator calls a "procumbent" riding position.

Not getting enough vitamin D can weaken bones, teeth, and muscles by interfering with calcium absorption. Now there's another reason to avoid a serious D deficiency: it can make respiratory tract infections much worse, according to a new study.

While heartburn medication can be a lifesaver for those suffering from gastric reflux, several studies over the years have indicated that the drugs could increase stomach cancer risks more than threefold. A new meta analysis says that's likely not the case.

Using the largest sample of super-agers to date, scientists have found convincing evidence that supports what many of us have suspected: Longevity isn’t just about healthy lifestyle choices, but also a good draw in the genetic lottery.

Researchers have developed a spray-on powder that turns into a wound-conforming gel when it comes in contact with blood. The breakthrough has the possibility of dramatically improving wound care in combat and other life-threatening situations.

The first-of-a-kind brain-stimulation device approved to treat attention-deficit/hyperactivity disorder in the US has had its efficacy questioned, with scientists believing that its Food and Drug Administration approval was based on poor science.

You might be more familiar with it as a versatile fibrous material or the staple food of giant pandas, but bamboo has entered the health-food realm thanks to the first review into its benefits. They include aiding blood sugar regulation and gut health.

Most mammals produce their own Vitamin C but around 60 million years ago, humans lost this ability. New research suggests this was not an innocuous evolutionary shift but actually a clever defense against the parasitic infections.

Instead of focusing on your sore arm after your next vaccine, you might want to think good thoughts. A new study that trained people in the power of positive thinking showed that the practice can significantly boost antibodies created by the jab.
