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.

Imagine if there was protective clothing that usually stayed soft and comfortable, but that could instantly harden when needed. Such technology may someday be possible, thanks to a new understanding of a tiny animal's shell.

DARPA has awarded contracts to FLIR Systems, Leidos, and Charles River Analytics to develop new kit to protect soldiers and responders against chemical and biological (CB) threats using lighter, more comfortable and more versatile suits.
-
A new flow visualization study from the National Institute of Standards and Technology (NIST) starkly demonstrates why face masks with exhalation valves are not effective for slowing the spread of COVID-19.

Researchers claim they've come up with the world's first manufactured non-cuttable material, just 15 percent the density of steel and impervious to drills or angle grinders. They say it could make for indestructible bike locks and lightweight armor.
-
Chitin derived from shrimps, mushrooms, and other organisms may lead to new 3D-printed, multi-layered polymer coatings to protect soldiers against bullets, lasers, toxic gases, microbes, and other hazards.
-
Although seawalls certainly do protect coastal communities from storm surge waves, those walls can be unsightly, and restrict access to the water. A proposed new system gets around those problems, by doubling as a canopy when not serving storm duty.

In China right now, you'll see many people wearing surgical masks to protect against coronavirus. A scientist claims that such masks may actually do more harm than good, if handled improperly – so he's created a coating that could change that.

Although the bulletproof shields used by police officers are definitely life-savers, the things are also quite heavy and bulky. The origami-inspired Swift Shield offers an alternative, as it folds down into a lightweight package when not in use.
-
Helmets could soon offer better protection while also being more comfortable, thanks to a new padding material developed by HRL Laboratories. It's claimed to be better than foam at withstanding impacts, while also keeping heads cooler and drier.
-
In certain parts of the world, people such as surfers stand a real risk of being bitten by sharks. According to a recent study, however, a lightweight wetsuit fabric could greatly reduce the seriousness of injuries when such attacks occur.
