One method of 3D printing involves selectively exposing liquid resin to ultraviolet (UV) light, causing that resin to harden into a solid. Now, scientists have developed a new resin that works with safer, more energy-efficient visible light.

Some vaccines aren't very effective, which is due at least partially to the amount of time that they're active within the body. A new injectable hydrogel, however, could allow them to act for a longer period of time, making them more potent.

The US Army has put the call out for new homegrown uniforms that are not only fire retardant but also insect repellent, and a team has answered with a new material made by treating a commercially available nylon-cotton blend with non-toxic chemicals.

After wastewater such as sewage has been processed at water treatment plants, a sandy grit is typically left over. And while that grit usually ends up in landfills, it could soon instead be used in a more eco-friendly pothole repair material.

What kind of threat can tiny plastic fragments pose to the health of living organisms? Scientists have turned to human tissue for answers, and discovered evidence of plastic fragments in every single sample they studied.

Researchers have developed a new type of fabric that keeps the wearer much cooler. Made from different polymers in a relatively simple way, it can efficiently transfer heat and wick away sweat, while remaining water repellent from the outside.

It goes without saying that as a chemist stirs a solution in their lab, they need to check how its characteristics change. A new "Smart Stirrer" has been designed with that in mind, as it automatically detects and reports transformations.

Evaporation is one of the most enduring methods of purifying water to make it drinkable. Now researchers in China have developed a novel device made of wood that can do just that, by employing bacteria to help build key nanostructures.

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.

Researchers have created synthetic red blood cells that have all of the useful properties of the real thing, plus a few new tricks. These new cells could be put to work carrying oxygen or drugs through the body, sensing toxins, and other tasks.

Although 3D printers can produce a wide variety of objects, the size of each item is limited by the size of the printer. Scientists have now developed a way of getting around that limitation, using a resin that expands when heated.

It was just a couple of years ago that we heard about a kinder, gentler hair dye that incorporated graphene. Well, scientists have now had success utilizing another, less exotic substance – synthetic melanin.
