A newly discovered vulnerability could allow cybercriminals to silently hijack the artificial intelligence (AI) systems in self-driving cars, raising concerns about the security of autonomous systems increasingly used on public roads. Georgia Tech cybersecurity researchers […]
A small but mighty piece of lab equipment, about the size of a cellphone, has arrived at the International Space Station after launching with NASA’s SpaceX Crew-12 mission. NASA aims to use the off-the-shelf device, […]
Ribonucleotide reductases (RNR) are indispensable enzymes that convert ribonucleotides to deoxyribonucleotides (dNTPs), the precursors to make up DNA. Because DNA synthesis is fundamental to cell survival, RNR activity must be tightly controlled. In bacteria, this […]
A protein called neurofilament light chain (NfL)—studied in humans in the context of neurodegenerative diseases and aging—is also detectable in the blood of numerous animals, and NfL levels increase with age in mice, cats, dogs […]
New kinds of aircraft taking to the skies could mean unfamiliar sounds overhead—and where you’re hearing them might matter, according to new NASA research. NASA aeronautics has worked for years to enable new air transportation […]
