Newly discovered ransomware uses BitLocker to encrypt victim data
GOING NATIVE — ShrinkLocker is the latest ransomware to use Windows' full-disk encryption. Dan Goodin - May 24, 2024 10:06 pm UTC A previously unknown piece of ransomware, dubbed ShrinkLocker, encrypts victim data using the BitLocker feature built into the Windows operating system. BitLocker is a full-volume encryptor that debuted in 2007 with the release
13 new papillomaviruses discovered in Antarctic seals
Papillomaviruses are non-enveloped, circular, double-stranded DNA viruses known to infect squamous and mucosal epithelial cells. There are 53 genera and 133 viral species whose members infect a variety of mammalian, avian, reptilian, and fish species. Scientists at Arizona State University recently discovered 13 novel papillomaviruses carried by Antarctic seals. The discovery could help scientists understand
Huge backdoor discovered that could compromise SSH logins on Linux
Microsoft employee Andres Freund has shared finding odd symptoms in the xz package on Debian installations. Freund noticed that ssh login was requiring a lot of CPU and decided to investigate leading to the discovery.The vulnerability has received the maximum security ratings with a CVS score of 10 and a Red Hat Product Security critical
Astronomers discovered a rare system containing two long-period planets
Using data from NASA’s Transiting Exoplanet Survey Satellite, or TESS, astronomers at MIT, the University of New Mexico, and elsewhere have discovered a rare system containing two long-period planets orbiting TOI-4600. One planet has an orbit of 82 days, whereas the second planet orbits the star every 482 days. TOI-4600 is a nearby star located

Star Discovered Orbiting Milky Way’s Supermassive Black Hole Every 4 Years
Astronomers have discovered a star that orbits the supermassive black hole at the center of our galaxy every four years. That’s the shortest orbit ever observed around a supermassive black hole. The newly discovered star, called S4716, is about four times more massive than our Sun and twice as hot. It survives extraordinary conditions, orbiting…
There are several different anti-anxiety medications available. Most of them are not considered effective and have unwanted side effects. Identifying mechanisms that underlie fear and anxiety could develop better treatments for anxiety disorders. Neuroscientists from Bristol’s School of Physiology, Pharmacology, and Neuroscience investigated how the brain’s cerebellum influences activity in another brain area called the…
Discovered: An easier way to create ‘flexible diamonds’
Artist's conception showing how guided diamond nanothread synthesis occurs when the starting material is compressed between the points of two diamonds. This diamond anvil cell is a frequently used tool for bringing matter to extreme pressures and Carnegie scientists have been pioneering leaders in deploying this research technique for decades.

Scientists have discovered a long-predicted magnetic state of matter
Almost six decades ago, physicists were interested to know- what happens if making the electronic ‘energy gap’ between an insulator and a conductor smaller and smaller. Will it change a simple insulator into a simple metal where the electrons can move freely, or does something more interesting happen? Physicists predicted that- under certain conditions, it…
Scientists discovered a strange new type of star that has them puzzled
A new study written by German astronomers outlines a new type of star we’ve never seen before. The new hot subdwarf star was discovered by a team of researchers led by Professor Klaus Werner from the University of Tübingen. Scientists believe the new star covered in helium-burning ash is the result of a rare stellar…
