It goes without saying that the earlier someone can be warned of an impending heart attack or stroke, the better. A new skin patch could provide such warnings, by sending ultrasound pulses into the wearer's body.

A new type of wearable leverages the surprisingly large sweat output of the fingertips to generate electricity when the user is sedentary or even sleeping, providing a potentially round-the-clock source of power.

Building on a long-standing observation linking vitamin D deficiency to increased risk of colorectal cancer, a new study from UCSD has found countries where people experience lower levels of UVB light often report higher rates of colorectal cancer.

After open-heart surgery has been performed, the scar tissue that forms on the heart will sometimes stick to the tissue surrounding it. Such complications are known as adhesions, and a new hydrogel may help keep them from occurring.

Bacteria have a nasty ability to rapidly evolve, allowing them to evade antibiotics in short order. But now, scientists at UC San Diego have used evolution against them, by “training” bacteria-killing viruses to anticipate their next moves.

Most conventional light microscopes have a resolution of 200 nanometers – this means that imaged objects which are any closer together won't be seen as separate items. A new high-tech microscope slide, however, boosts that figure to 40 nanometers.

We've been hearing a lot lately about micro-robots, that could one day perform tasks such as capturing pollutants from the environment. Scientists have now created a sturdy batch of such bots, that heal back together when cut in two.

A new proof-of-concept study suggests CRISPR gene therapy may be a promising alternative to opioids for chronic pain. The preliminary investigation demonstrated lowered pain sensitivity in mice after temporarily repressing activity of a specific gene.

When it comes to renewable energy, many cities combine multiple sources, such as solar panels and wind turbines. Scientists have now taken a similar approach with a "smart" shirt that generates electricity via both sweat and movement.

Scientists have made a breakthrough around how lithium-metal batteries function at ultra-low temperatures, building a version that relies on weak bonds in its electrolyte to offer unprecedented performance in the cold.

Soft robots are gaining a lot of attention in research circles, and from an engineering lab at the University of California, San Diego comes an interesting new example of this technology in the form of a robot that can move without any electronics.

A new device out of UC San Diego takes flexible electronics into new territory, with engineers building what they say is the first wearable capable of monitoring cardiovascular signals and multiple biochemicals in the body at the same time.
