The first lunar rocks brought back to Earth in decades show the Moon was volcanically active more recently than previously thought, Chinese scientists said Tuesday.

A Chinese spacecraft carried lunar rocks and soil to Earth last year—humanity’s first mission in four decades to collect samples from the Moon, and a milestone for Beijing’s growing space program.

The samples included basalt—a form of cooled lava—from 2.03 billion years ago, scientists found, pushing the last known date of volcanic activity on the moon closer to the present day by as much as 900 million years.

Analysis of the samples “reveals that the Moon’s interior was still evolving at around two billion years ago”, the Chin...

Injection prevented severe pediatric form of disease in mice, could be used to treat adult glaucoma. A Northwestern Medicine study in mice has identified new treatment targets for glaucoma, including preventing a severe pediatric form of glaucoma, as well as uncovering a possible new class of therapy for the most common form of glaucoma in adults.

In people with high pressure glaucoma, fluid in the eye doesn’t properly drain and builds up pressure on the optic nerve, leading to vision loss. It affects 60 million people worldwide and is the most common cause of blindness in people over 60 years old.

While there are a few treatments available for open angle glaucoma, the most common form of glaucoma in adults (eye drops, oral medication, laser treatments), there are no cures, and ...

Novel theorem demonstrates convolutional neural networks can always be trained on quantum computers, overcoming threat of ‘barren plateaus’ in optimization problems. Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. While a fundamental solvability problem known as “barren plateaus” has limited the application of these neural networks for large data sets, new research overcomes that Achilles heel with a rigorous proof that guarantees scalability.

“The way you cons...

The cosmic boundary, perhaps caused by a young Jupiter or a wind from the solar system emerging, likely shaped the composition of infant planets. In the early solar system, a “protoplanetary disk” of dust and gas rotated around the sun and eventually coalesced into the planets we know today.

A new analysis of ancient meteorites by scientists at MIT and elsewhere suggests that a mysterious gap existed within this disk around 4...
