The Raptor engine, designed to power the ship that will send humans to Mars and beyond, has been racking up impressive test results.
Aug. 18 (UPI) — New research suggests harmful cosmic rays from a nearby supernova might have caused the extinction events that form the boundary between the Devonian-Carboniferous periods.
Around 360 million years ago, a lengthy period of biodiversity declines culminated in a series of extinction events that saw 19 percent of all families and 50 percent of all genera disappear.
Scientists have previously unearthed a diversity of Late Devonian plant spores that show evidence of being burnt by ultraviolet light, signs of a prolonged ozone-depletion event.
SpaceX, the Elon Musk-led company that recently became the first business in history to send astronauts into Earth’s orbit, is parlaying its successes into big money.
Nearly three-quarters of older adults with dementia have filled prescriptions for medicines that act on their brain and nervous system, but aren’t designed for dementia, a new study shows.
That’s despite the special risks that such drugs carry for older adults—and the lack of evidence that they actually ease the dementia-related behavior problems that often prompt a doctor’s prescription in patients with Alzheimer’s disease and related disorders. In fact, some of the drugs have been linked to worse cognitive symptoms in old adults.
The study looks at several classes of psychoactive drugs, including ones that the federal government has actively encouraged nursing homes to limit using in residents with dementia. The new study suggests a need to reduce prescribing to people living at home with dementia, too.
A leading expert in socially responsible technology innovation Dr Andrew Maynard told us “I think Musk’s overreaching and he probably knows it.
”That said, Elon Musk has got a track record of doing things that other people said can’t be done. So I think that this is going to be an interesting space because of that… [But] I think we’re a long way from understanding how this works.
”Even with Elon Musk’s system you have around ten thousand electrodes. There are billions of neurons in your brain. It’s a needle in a haystack”.
The Tetrad Automated Causal Discovery Platform, a software and text project developed by Peter Spirtes, Clark Glymour, Richard Scheines and Joe Ramsey of Carnegie Mellon University’s Department of Philosophy, earned the “Leader” Award at the 2020 World Artificial Intelligence Conference this past July.

“I HOPE THIS STUDY CHANGES THE DIALOG AROUND HERPES RESEARCH AND OPENS UP THE IDEA THAT WE CAN START THINKING ABOUT CURE, RATHER THAN JUST CONTROL OF THE VIRUS.”
In a landmark study, researchers have successfully used gene editing to remove the oral herpes virus (HSV-1) in mice.
While previous research has mostly focused on treating and suppressing the sometimes painful symptoms of herpes, this study took a more radical approach by attempting to eliminate the virus altogether.
