From access cards and key fobs to Bluetooth speakers, the security of communication between wireless devices is critical in maintaining privacy and preventing theft. Unfortunately, these tools are not foolproof and information on how to hack, clone and bypass these systems is becoming easier to find. That’s why U.S. National Science Foundation-supported electrical engineers at…
Ring Video Doorbells have become super popular for so many reasons.

Obesity is a risk factor for metabolic pathologies such as insulin resistance, T2D, dyslipidemia, cardiovascular disease, and cancer. The pathophysiology of obesity-induced metabolic complications includes chronic low-grade inflammation, oxidative stress, mitochondrial dysfunction, impaired angiogenesis, hypoxia, and cell death. A research team from the University of Barcelona and the CIBERobn has developed a way to fight…
For the price, it’d be silly not to take advantage of an AirTag. @xguntherc May 30, 2023, 4:04 pm EST | 5 min read Justin Duino / Review Geek Even when you’re headed to a tranquil beach, traveling for a vacation can be stressful, especially if the airline loses your bag. It’s one of the…
In 1346, Tartar leader Khan Janibeg laid siege to a Genoese city in Crimea called Kaffa in hopes of removing the Italians from this central foothold. What happened next has become part-legend, part-historical record: As the Tartars waited outside Kaffa’s walls, the soldiers began to fall one by one to a terrible disease, the plague.Out…

Scientific American Custom Media, in partnership with The Kavli Prize, spoke with James to learn about his discoveries and the future of this work. Hall: James Rothman was pleasantly surprised when he received The Kavli Prize in Neuroscience. James Rothman: I’d always thought of myself as a biochemist first and a cell biologist second. And…
On March 15, the US Navy launched a torpedo-shaped robot into the Persian Gulf from the back of a helicopter. The robot was a Slocum glider, an uncrewed sensing tool that can collect data on ocean conditions below the surface. Dropping it from a helicopter was a proof of concept, a test towards expanding the…
Layers of Earth’s atmosphere are shown in a view looking across Earth’s surface from the International Space Station. Credit: NASANew research by Lawrence Livermore National Laboratory scientists reveals that human activities are undeniably altering the thermal structure of Earth’s atmosphere. By expanding climate “fingerprinting” to the mid-to upper stratosphere, the team has improved the detection…
But that wasn’t the only relevant genome change that the researchers found. They also identified a mutation in an enhancer that regulates the expression of some genes in the developmentally important hox group. Hox genes specify the general body plan in all bilaterally symmetrical animals. One subset of them, the hoxa gene cluster, is usually…
