When producing "smart fabrics" made of conductive fibers, it can be difficult placing functional elements such as electrodes in specific locations along those fibers. A new polymer, however, could make doing so much easier.

If you were planning to perform open-heart surgery on someone, it would definitely help if you could first do a "dry run" on an exact replica of their heart. Doing so may soon be possible, thanks to a recent advance in 3D printing technology.

Researchers have developed a way to treat male infertility by delivering nanoparticles loaded with proteins directly into the testes. In tests in mice, previously infertile animals were soon able to father pups at a similar rate as unaffected mice.

Given that not everyone has the same tolerance for hot chilis, it would be good if there were a simple, portable means of objectively assessing how hot they are. Well, scientists have developed just such a gadget – and it plugs into a smartphone.

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.
