A compound in beets that gives the vegetable its distinctive red color could eventually help slow the accumulation of misfolded proteins in the brain, a process that is associated with Alzheimer’s disease. Scientists say this discovery could lead to the development of drugs that could alleviate some of the long-term effects of the disease, the world’s leading cause of dementia.

A recent Stanford cancer study that cured 97 percent of mice from tumors has now moved on to soliciting human volunteers for a new cutting-edge medical trial.

The trial is part of a gathering wave of research into immunotherapy, a type of treatment that fights cancer by using the body’s immune system to attack tumors.

“Getting the immune system to fight cancer is one of the most recent developments in cancer,” Dr. Ronald Levy, a Stanford oncology professor who is leading the study, told SFGATE. “People need to know that this is in its early days and we are still looking for safety and looking to make this as good as it can be.”

China’s Tiangong-1 space station is set to make an uncontrolled reentry into the Earth’s atmosphere on or around April 1. The update from the Aerospace Corporation, which is tracking the abandoned orbital laboratory, predicts that it will make its final plunge at 00:00 GMT on April 1 with a margin of error of ±36 hours, when it will burn up somewhere between 43° North and 43° South latitudes.

Launched on September 30, 2011 from the Jiuquan Satellite Launch Center, China, atop a Long March 2F/G rocket, the Tiangong-1 was China’s first space station and was designed to accommodate two astronauts. In 2012, it was visited by the three-astronaut Shenzhou 9 mission that included China’s first female astronaut, and in 2013 by Shenzhou 10.

A lzheimer’s sufferers could once again remember the faces of loved ones, or find their way back home, after scientists developed a way to boost memories.

In a groundbreaking pilot study, US researchers recorded memories as they were being formed and then later played them back into the brains of 10 patients.

They found that it increased memory performance by up to 37 per cent.

Research from Google Cloud finds that applying AI to medicine is tricky.

Dario Gil shares the future of quantum computing.

Scientists at the Department of Energy’s Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. Their studies will enable advancements in quantum computing, sensing, simulation, and materials development.

The researchers’ experimental results were recently published in Physical Review B Rapid Communication and Optics Letters.

Quantum information is considered fragile because it can be lost when the system in which it is encoded interacts with its environment, a process called dissipation. Scientists with ORNL’s Computing and Computational Sciences and Physical Sciences directorates and Vanderbilt University have collaborated to develop methods that will help them control—or drive—the “leaky,” dissipative behavior inherent in quantum systems.

A class of antibiotics heralded as an essential future weapon against drug-resistant superbugs passed an important test. There’s now evidence that they can be used to treat serious infections in live animals (in vivo) without being toxic.

Researchers created simplified, synthetic versions of teixobactin, a protein produced by certain dirt-loving bacteria that was first discovered in 2015. They tested the teixobactin in lab mice whose eyes were infected with one of several germs, including antibiotic-resistant strains of Staphylococcus aureus and Enterococcus. The most successful of these analogues was found to leave animal cells alone while still wiping out more than 99 percent of the bacteria in the infected eye.

The findings were published in January in the Journal of Medicinal Chemistry.

Alphabet’s self-driving arm Waymo is introducing a new vehicle into its fleet of driverless rides, an all-electric car produced by Jaguar Land Rover.

Waymo unveiled the new vehicle, called the Jaguar I-Pace, at a press event in New York City on Tuesday and said it expected to begin production on the cars equipped with its technology in 2020. In the first two years, the companies expect to manufacture 20,000 cars.

The vehicles will first be available in a ride-hail service in Phoenix, Ariz., where the company will begin testing prototypes this year. Waymo currently has a fleet of driverless Chrysler Pacifica vans as part of its ongoing agreement with Fiat Chrysler.
