A new study has produced first-of-a-kind scientific evidence of the connection between stress and graying hair, identifying proteins that seem to drive this process while also demonstrating how it might even be reversed.

If you smiled at someone and they didn't smile back, you'd probably find it off-putting. Well, that's what usually happens if you smile at a humanoid robot … but not in the case of the expression-mirroring EVA.

Results from a trial testing an ultrasound therapy for hypertension show the treatment can deliver meaningful reductions in blood pressure. The treatment is based on a hypothesis that disrupting signals from renal nerves can reduce blood pressure.

Geologists have studied tiny fluid impurities in diamonds to figure out how old humanity’s favorite rocks might be. They identified three periods of diamond formation in Africa over billions of years, with intriguing implications for ancient Earth.

Engineers at Columbia University have developed the smallest single-chip system ever created, which can be implanted with a hypodermic needle to measure temperature inside the body, and possibly much more.

When it comes to the 3D printing of metal, a process known as selective laser sintering (SLS) is most commonly used. An upside-down variation on the technique has now been developed, for printing single objects out of different materials.

Scientists at Columbia University have developed a potential new treatment for a major source of blindness in the form of eye drops that preserve retinal function, with tests on human subjects now in the works.

The western United States has been suffering drought since 2000. A new study has examined extreme droughts in the region dating back 1,200 years, and found that the current conditions have the makings of a “megadrought” that could last decades.

In 2017, scientists found the first direct evidence that autoimmunity may play a role in the onset of Parkinson’s disease, and have now uncovered further evidence of how the immune system contributes to the development of the disease.

Rupturing tendons or ligaments like an anterior cruciate ligament in the knees can mean long stints on the sidelines, but a new type of synthetic material promises to help things along by acting as a scaffold to accelerate the regeneration of tissue.

A new study has calculated that the Greenland ice sheet lost hundreds of billions of tons of ice last year, marking the biggest drop in its ice mass since records began in 1948. The team found that unusual pressure patterns had a devastating impact.

Climate change threatens to shake up the lifestyles of many animals around the world and a new study involving GPS-tagged birds has revealed that for the American robin these wheels are already very much in motion.
