While we've been hearing a lot about wearable piezoelectric devices that produce electricity from people's movements, such gadgets don't work well under certain conditions. A new bioelectric wearable, however, could excel where they falter.

Microbial fuel cells are a promising new way to generate electricity, but so far they’re plagued by inefficiency. Researchers at UCLA have now found a way to wring more energy out of them, by feeding the bacteria silver to make them more conductive.

An international team of scientists has calculated that a crewed mission to Mars should only last a maximum of four years if the astronauts' health isn't to be endangered by prolonged exposure to cosmic radiation.

An experimental gene therapy developed to treat children born with a rare immunodeficiency disease has demonstrated extraordinary efficacy according to a new long-term follow-up study published in the New England Journal of Medicine.

Unfortunately there isn’t much that doctors can do to repair the damage after a spinal cord injury. But UCLA researchers have shown in tests in mice that injections of a porous scaffold material can help the body patch up the damage.

Scientists at UCLA and Stanford University have carried out a first-of-a-kind analysis of 20-month-old lab-grown brain organoids to find that they had matured much like a human brain, following an internal clock to guide their development.

Five years ago, we heard how a team at UCLA had used ultrasound to seemingly "jump start" a patient out of a coma. At the time, the scientists wondered if such results could be repeated. They have now done it two more times.

A new study projects the COVID-19 pandemic to generate the largest single-year decline in US life expectancy in at least 40 years. The declines are especially prominent in minority communities, and are expected to continue over the coming years.

Lightning is a major trigger for wildfires, like the record-breaking blazes that devastated Australia and California this year. But what if we could redirect lightning to strike safely? Graphene particles trapped in a tractor beam could do just that.

Scar tissue is an effective short-term solution to quickly patch up wounded skin, but it’s not so great long-term. A new hydrogel helps by triggering a regenerative immune response, so skin heals healthier and stronger without scarring.

By putting a new spin on decades-old thermoelectric technology, scientists at the University of California, Los Angeles (UCLA) have developed a tiny microscopic cooling device they describe as the "world’s smallest refrigerator."

New research has identified a dramatic change to the nature and purpose of sleep in babies, occurring around the age of two. The discovery suggests sleep initially aides brain building and neurodevelopment before rapidly switching to a reparative role.
