If you've ever peeked below the surface of the ocean, you'll have seen seaweed waving back and forth in the current. Scientists from China's Dalian Maritime University have now utilized that same motion in an underwater energy-harvesting device.

Digital data storage is far from permanent. The data on your hard drive or flash drive probably won't last more than a few decades, but Harvard researchers have created what they say is a much longer-term alternative using spots of glowing dye.

As most of us have noticed over the past couple of years, face masks can sometimes be a hassle – necessary though they are. An experimental new mask, though, automatically becomes easier to breathe through when maximum air filtration isn't required.

While wearable sensors can detect airborne toxins in the user's environment, any one device can usually only identify a few such substances. A potentially much more useful new sensor, however, can reportedly detect over 100 at once.

Scientists in China are throwing a new potential hair loss treatment into the mix that uses a dissolvable microneedle patch to stimulate hair growth, with the technology proving high effective in mouse models of hereditary pattern baldness.

When it comes to contraceptives, men typically have to remember to use a condom, or get a difficult-to-reverse vasectomy. There may soon be a new option, however, in the form of injected particles that are magnetically guided to the testes.

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.
