Their work is published in Science Advances.
Tissint, which crash landed in Morocco more than 11 years ago, is one of only five Martian meteorites that have been observed as they fell to Earth. Pieces of it were found...
(BBC News) Republican House Speaker Kevin McCarthy has called for Congress to investigate U.S. President Joe Biden following the discovery of two batches of classified documents – one of which was found at Biden's home.
McCarthy accused Biden of hypocrisy, pointing to the Justice Department's probe of former President Donald Trump for allegedly mishandling classified files.

(California Institute of Technology) Astronomers have used an intense burst of radio waves originating from a nearby galaxy to inspect the halo of gas cocooning our Milky Way galaxy. The scientists studied the way that the light of the so-called fast radio burst, or FRB, was dispersed as it travelled from deep space into our galaxy as a means to estimate how much matter resides in the galaxy's halo. This is a bit like...

The International Thermonuclear Experimental Reactor (ITER) project seeks to prove the feasibility of fusion as a large-scale and carbon-free source of energy. Installed at a site in southern France, the decades-old initiative has a long history of technical challenges and cost...

(University of Southern California) The human brain holds many clues about a person's long-term health. In fact, research shows that a person's brain age is a more useful and accurate predictor of health risks and future disease than birthdate. Now, a new artificial intelligence (AI) model that analyzes magnetic resonance imaging (MRI) brain scans developed by USC researchers could be used to accurately capture cognitive decline linked to neurodegenerative diseases such as Alzheimer's much...
(Los Angeles Times) Personal emails linked to 235 million Twitter accounts hacked some time ago have been exposed, according to Israeli security researcher Alon Gal — making millions vulnerable to having their accounts compromised or identities exposed if they have used the site anonymously to criticize oppressive governments, for instance.
Gal, co-founder and chief technology officer at cybersecurity firm Hudson Rock, wrote in a LinkedIn post this week that the leak “will unfortunately lead to a...
(University of Southern California) There is no simple solution to the deadly overdose epidemic, which costs 100,000 lives in the U.S. each year and is erasing gains in life expectancy. But a team of USC researchers has found that one low-cost intervention can make a difference; a letter notifying providers their patient has died from an overdose.
A 2018 study by the team found that notifying clinicians through an informational letter from their county's medical examiner that...
