Although N95 face masks are quite effective at blocking transmission of the COVID-19-causing SARS-CoV-2 virus, they're also intended to be used only a few times at most. A new removable membrane, however, could make them much more reusable.

Radio waves travel poorly through the water, which makes it difficult for divers or submersibles to wirelessly transmit information to the surface. Scientists are trying to change that, though, by developing an underwater version of Wi-Fi.

The "sea skater" is one of the few insects that lives full-time in a marine environment. Scientists are now taking a closer look at how the animal repels water, with an eye towards the development of more hydrodynamic ship hulls.

Given that solar panels lie in direct sunlight, it goes without saying that they can get pretty hot. Unfortunately, though, they also get less efficient as they heat up. That said, a new gel could help cool them … without using any electricity.

Responsible for millions of dollars in crop losses annually, the red palm weevil is a flying beetle that lays its eggs inside date palm trees. It could soon be possible to detect such infestations earlier than ever, using fiber optic cables.

It's vitally important to monitor the water quality of fish farms, as problems such as pollution can quickly prove disastrous. A small new floating cube was designed with this in mind, as it continuously tracks multiple factors.

Given the scarcity of fresh water in many regions, it does seem a bit crazy to be flushing the stuff down the toilet. And while a few coastal areas use seawater instead, doing so is problematic in its own way – new research, however, may change that.

Scientists are coming up with some creative new methods to fight cancer. Now, a new study has found that iron nanowires could deliver a three-pronged attack against cancer cells, using heat, vibrations and drugs together.

For a person with diabetes, monitoring blood glucose levels is an everyday hassle, usually involving finger pricks. A new prototype glucose monitor has been designed to power itself from that same glucose in bodily fluids.

A number of groups have already developed so-called "electronic skin," which adds electronic functionality to a user's natural skin. A new magnetic take on the technology, however, does away with the need for integrated electronics and power sources.

In the chemical-production industry, energy-intensive processes are constantly being used to remove unwanted molecules from liquids. It now looks like much of that energy could be saved, however, by utilizing filters made from plastic bottles.

The smaller and lighter electronics get, the more ways they can be used. A team of researchers has come up with a compact radar system the size of a matchbox that could be deployed in drones and other gadgets where portability and low cost are important.
