Our taste for bread and pasta wouldn’t be the same if not for our ability to break down starch, a talent Peru’s Andean populations have taken to the extreme by evolving a unique profile of genes.

A recent discovery suggests a hit of the brain’s "feel-good" chemical, dopamine, may have a rather surprising effect on our perception of past experiences, drawing out novel moments in our memories while letting more dull experiences become condensed.

Zinc oxide remains one of the best forms of sun protection thanks to its ability to block both UVB and UVA rays. However, few really appreciate its thick white look – except, maybe, lifeguards in the '80s. UCLA researchers believe they have a solution.

When COVID-19 lockdowns emptied city streets, urban environments changed almost overnight. New research suggests that Los Angeles city birds responded just as quickly, with measurable shifts in beak shape in offspring born during the lockdown period.

A one-time gene therapy using a patient’s own stem cells has effectively cured a deadly immune disorder in 95% of treated children, offering a lasting, donor-free solution to ADA-SCID, known as the “bubble boy” disease.

A new study shows that a personalized, precise form of brain stimulation, HD-tDCS, can rapidly ease depression symptoms – and even reduce anxiety – offering a promising drug-free alternative with only mild side effects.

When scientists study obesity, it's often focused on genetics, physical activity and poor eating habits. However, new findings show that stress, hardship, isolation and social inequality create the biological environment that underpins the epidemic.

We've already seen a pen that helps people with Parkinson's disease to write clearly, but this one is a little different. By assessing its user's hand movements as they write, it can provide an early warning that they're developing the condition.

One of the ketogenic diet's major perceived drawbacks is an increase in LDL, or so-called bad cholesterol. A new study, though, says that this cholesterol spike doesn't fit the conventional science in terms of its disease-causing ability.

UCLA researchers have developed a tiny sensor to monitor metabolites – substances produced or used when your body breaks down food or medication – far more extensively than current methods. It could unlock better disease diagnosis and drug development.

There's newfound hope for stroke patients in recovery, with what researchers believe is the very first drug that can comprehensively deliver rehabilitation without the need for challenging long-term physical therapy.

Astronomers have discovered an exoplanet with a tail, like a gigantic comet. The planet, known as WASP-69b, is slowly evaporating in the radiation of its host star.
