Scientists at University of California, Los Angeles have uncovered a key mechanism behind the retention of memories, and shown how targeting it with an existing drug used to treat HIV could strengthen human memory during middle age.

Scientists have discovered a new form of space weather – superfast electron rains that precipitate into the atmosphere from the radiation belts. The rains could affect satellites, spacecraft and astronauts, but aren’t accounted for in current models.

Perovskites are promising solar cell candidates, but a major downside is that they degrade in direct sunlight. Researchers have now uncovered a root cause of the problem, and found a simple fix that can be applied during the manufacturing process.

It's important for people with conditions such as depression and anxiety to know when they're becoming stressed, so they can initiate coping strategies. An experimental smartwatch could someday warn them, by detecting a stress hormone in their sweat.

HIV is hard to kill as it hides out in cellular reservoirs, but a growing body of work shows that a cure might be possible. In a new study, improvements to a previous “kick and kill” technique completely cleared HIV in 40 percent of treated mice.

Good news for those who like racing through audiobooks. A study has found learning is not negatively effected when students watch recorded lectures a faster playback speeds. However, comprehension did suffer when playback reached 2.5 times normal speed.

A new study by the Planetary Science Institute and UCLA confirms that there are areas in the lunar south polar region where frozen carbon dioxide could exist, raising hopes that there could be significant resources to support future Moon missions.

A long-term study tracking children who received an experimental gene therapy as part of an early-stage trial is reporting the treatment safe and effective up to 10 years later. The study offers insight into the long-lasting effects of gene therapy.

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.
