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.

A research team at Columbia University has made an exciting discovery, finding that a compound currently under development for a rare kidney stone disease can starve pancreatic cancer cells of a key amino acid they depend on for survival.

A study published in the journal Science has tracked the spread of the novel coronavirus across China in January, finding 86 percent of early infections were undocumented. The study says a “radical increase” in testing is vital to slow the spread.

INTEGRATE is a newly-developed version of CRISPR that edits genes more gently. It uses “jumping genes” that insert large sequences of DNA without breaking the strands, and now scientists have imaged the mechanism at work for the first time.

Not only do many people walk around with their eyes glued to their smartphones, but a lot of them also wear headphones. With that in mind, scientists are developing headphones that warn their wearers when vehicles are approaching.

Scientists have developed a tiny new kind of bio-compatible laser that could, theoretically, be implanted inside living tissues without causing them damage.
