No matter how hard we may try, we can't really tell if we've got bad breath – and asking someone else to sniff our breath for us can be awkward. It's now possible that before too long, however, a portable "thumb-size" device could let us know.

After someone has suffered a heart attack, non-beating scar tissue grows back in place of the damaged cardiac tissue, leaving the heart permanently weakened. A newly developed spray-on medication, however, may someday help change that.

Scientists in China have developed an artificial skin for prosthetic devices and robotics that changes color in response to force, mimicking the bruising process to offer a visual sign that damage has taken place.

Paramecium and certain other microbes move through liquid by whipping back and forth hairlike appendages known as cilia. Scientists have now developed a new type of synthetic cilia, which could find use in micro-robots and more.

Although women in First World countries are routinely diagnosed with and treated for vaginal yeast infections, doing so isn't always possible for women in impoverished nations. New fungus-detecting hygiene products, however, could make things easier.

It can be frustrating, when the jacket that you initially put on to keep you warm starts making you too hot. Jackets made from an experimental new reversible fabric, however, could both heat and cool their wearer.

The brewing of beer produces great quantities of leftover grain, which often ends up being processed into cattle feed. Scientists have developed a new method of extracting the protein and fiber from that waste, however, for use by humans.

Like most other commonly used types of plastic, polyurethane is typically made from non-renewable crude oil, and it takes centuries to break down when discarded. Now, however, scientists have created a biodegradable polyurethane-like polymer using fish waste.

Although Ceriporia lacerata fungus causes tree wood to rot, it also has a good side. According to a new study, adding the fungus to agricultural soil allows tomatoes to be grown using much less fertilizer.

We've been hearing a lot lately about micro-robots, that could one day perform tasks such as capturing pollutants from the environment. Scientists have now created a sturdy batch of such bots, that heal back together when cut in two.

Those purple corn chips you see in the store aren't just a gimmick – the corn's purple pigment actually has health benefits. Researchers have now devised a method of extracting more of it from the usually discarded cob, for a variety of uses.

Even though a properly-fitted sports helmet is vital to avoiding brain injuries, the fitting process is still largely a subjective one. A new pressure-sensitive cap, however, could objectively ensure that each athlete gets the right helmet.
