With the help of an AI model trained on videos of surgery videos, a robot system has successfully carried out difficult surgical tasks as skillfully as a humanIntuitivePerforming surgery takes years of training for humans, but a robot could learn the skill more easily with today’s AI technology. Researchers from Johns Hopkins University (JHU)...
An untreated loop of catheter tubing (left) alongside a clot-free coated loop Jayachandran Kizhakkedathu Research GroupWhen blood passes through medical devices like catheters or stents, there's a risk of clots forming, which can be harmful. A newly developed coating, inspired by biological processes, could prevent this without the need for blood-thinning drugs.How Blood Forms Clots...

Hacking a 50-bit RSA key is so easy you could do it with your cell phone in secondsRecent headlines claim Chinese researchers used D-Wave quantum computers to hack RSA, AES, and "military-grade encryption." This is both true and misleading.A May 2024 white paper in the Chinese Journal of Computers details how researchers used D-Wave's...
September 22: Pesto manages to make an average-sized king penguin look small Bronwyn Thompson/New AtlasA new viral sensation is taking the spotlight: Pesto, a nine-month-old king penguin chick, whose unusually large size has made him a global star. Hatched from an avocado-sized egg on January 30, 2024, at Sea Life Melbourne, Australia, Pesto now weighs...
Medical marijuana and cannabis products CBD oil, hemp leaves on a dark background. Flat lay, copy space MockupFor the first time, scientific evidence shows that a lesser-known component of the cannabis plant—cannabinol (CBN)—can provide longer and better-quality sleep. This breakthrough opens the door for the development of a cannabis-based sleep aid comparable to existing...
By analyzing your DNA and RNA with a computational pipeline and a curated database of pathogens, the mNGS system leads to far quicker diagnoses of rare diseasesGrumpyBeere / Pixabay (AI generated)Researchers at the University of California, San Francisco (UCSF) have developed an innovative genomic test capable of rapidly detecting nearly any pathogen in a...
Credit: PixabayOne of my most memorable experiences was back in the 90s when I was in the US Air Force. In November 1998, I found myself deployed to Kuwait, where I witnessed a spectacular meteor storm as the Leonids reached their peak on the morning of November 17th. The meteors came quickly and intensely,...
