Scientists have developed an advanced new type of humidity sensor inspired by camel noses that is capable of detecting low levels of water molecules in the air, giving it the potential to help find water sources in extreme environments.

Currently, when we're heading outside on a sunny day, we apply sunscreen to limit UV damage to our skin. Thanks to new research, however, we may soon apply a different sort of lotion to avoid frostbite on cold days.

Ice in and of itself isn't slippery – it becomes slippery when friction causes a thin layer of liquid water to form on top of it. Scientists have now applied that same principle to an injectable medication that could be used to treat osteoarthritis.

Although hearing aids do make life easier for many people, their limited battery life can be problematic. Scientists have set about addressing that shortcoming, by designing a hearing aid that requires no batteries.

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.
