Vaccine Panel Stacked by RFK Jr. Recommends Delaying MMRV Immunization

wired.com Emily Mullin 2025-09-19 04:59:44

A federal vaccine advisory committee made up of members hand-picked by Health and Human Services secretary Robert F. Kennedy Jr. recommended in an 8-3 vote on Thursday that the combined measles, mumps, rubella, and varicella (MMRV) vaccine should not be given before age 4, citing long-known evidence that shows a slightly increased risk for febrile seizures in that age group. Experts say that while frightening, febrile seizures—which are uncommon after vaccination—are usually short-lived and har

Below, we've listed some of the perks you should be using as an Amazon Prime member. Arguably, these incentives alone aren't worth the cost of a membership, but chances are at least one of them will come in handy. Amazo

New Phoenix attack bypasses Rowhammer defenses in DDR5 memory

bleepingcomputer.com Unknown 2025-09-27 05:01:24

Academic researchers have devised a new variant of Rowhammer attacks that bypass the latest protection mechanisms on DDR5 memory chips from SK Hynix. A Rowhammer attack works by repeatedly accessing specific rows of memory cells at high-speed read/write operations to cause enough electrical interference to alter the value of the nearby bits from one to zero and vice-versa (bit flipping). An attacker could potentialluy corrupt data, increase their privileges on the system, execute malicious cod

A while ago I got a ST Nucleo-H753ZI evaluation board because I wanted to try out Hubris, Oxide's embedded operating system.
