Hackers are exploiting a maximum-severity vulnerability that has the potential to give them complete control over thousands of servers, many of which handle mission-critical tasks inside data centers, the US Cybersecurity and Infrastructure Security Agency is warning.

The vulnerability, carrying a severity rating of 10 out of a possible 10, resides in the AMI MegaRAC, a widely used firmware package that allows large fleets of servers to be remotely accessed and managed even when power is unavailable or the operating system isn't functioning. These motherboard-attached microcontrollers, known as baseboard management controllers (BMCs), give extraordinary control over servers inside data centers.

Administrators use BMCs to reinstall operating systems, install or modify apps and make configuration changes to large numbers of servers, without physically being on premises and, in many cases, without the servers being turned on. Successful compromise of a single BMC can be used to pivot into internal networks and compromise all other BMCs.

NASA's Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights.

But chances are low the Space Launch System will making it to nine flights, and if it does, it's questionable if it would reach that point before 2040. The SLS rocket is a core piece of NASA's plan to return US astronauts to the Moon under the Artemis program, but the White House seeks to cancel the program in favor of cheaper commercial alternatives.

For the second time in less than a week, NASA test-fired new propulsion hardware Thursday that the agency would need to keep SLS alive. Last Friday, a new liquid-fueled RS-25 engine ignited on a test stand at NASA's Stennis Space Center in Mississippi. The hydrogen-fueled engine is the first of its kind to be manufactured since the end of the Space Shuttle program. This particular RS-25 engine is assigned to power the fifth flight of the SLS rocket, a mission known as Artemis V.

Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered. Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, through eyes and parts of brain, to the spinal cord. Mammals, though, have mostly lost this ability somewhere along their evolutionary path. Regeneration persisted, in a limited number of tissues, in just a few mammalian species like rabbits or goats.

“We were trying to learn how certain animals lost their regeneration capacity during evolution and then put back the responsible gene or pathway to reactivate the regeneration program,” says Wei Wang, a researcher at the National Institute of Biological Sciences in Beijing. Wang’s team has found one of those inactive regeneration genes, activated it, and brough back a limited regeneration ability to mice that did not have it before.

The idea Wang and his colleagues had was a comparative study to compare how the wound healing process works in regenerating and non-regenerating mammalian species. They chose rabbits as their regenerating mammals and mice as the non-regenerating species. As the reference organ, the team picked the ear pinna. “We wanted relatively simple structure that was easy to observe and yet composed of many different cell types,” Wang says. The test involved punching holes in the ear pinna of rabbits and mice and tracking the wound-repairing process.

The vaccine panel hand-selected by health secretary and anti-vaccine advocate Robert F. Kennedy Jr. on Thursday voted overwhelmingly to drop federal recommendations for seasonal flu shots that contain the ethyl-mercury containing preservative thimerosal. The panel did so after hearing a misleading and cherry-picked presentation from an anti-vaccine activist.

There is extensive data from the last quarter century proving that the antiseptic preservative is safe, with no harms identified beyond slight soreness at the injection site, but none of that data was presented during today's meeting.

The significance of the vote is unclear for now. The vast majority of seasonal influenza vaccines currently used in the US—about 96 percent of flu shots in 2024–2025—do not contain thimerosal. The preservative is only included in multi-dose vials of seasonal flu vaccines, where it prevents the growth of bacteria and fungi potentially introduced as doses are withdrawn.
