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.

While electroencephalography (EEG) can provide a lot of information on the electrical activity of an individual's brain, that person is required to wear a clumsy skull cap. Such caps could soon be replaced, however, with inkjet-printed scalp tattoos.

Not only have researchers identified how a common cellular protein affects aging, but they’ve tweaked the genes that produce it in fruit flies, extending healthy lifespan by 25% to 30%. The discovery opens the door to healthier aging in humans.

Researchers at UCLA have successfully devised a way to produce cement with 98% less CO2 emissions than traditional methods. The team achieved this by decomposing limestone to access calcium oxide (aka lime) without releasing carbon dioxide.

Nanosized particles that release glucagon, the hormone responsible for raising blood glucose levels, on-demand could mean that diabetics don’t need to worry about potentially dangerous low blood sugar levels, according to new research.

Manuka honey reduced breast cancer cell growth by 84% without harming healthy cells or causing major side effects, according to preliminary studies. The findings open the door to developing a natural, non-toxic supplementary, or potentially stand-alone, anticancer treatment.
