Original Title: Study on mice shows for the first time that the locus coeruleus, a brainstem region, is involved in the organization of sleep: it controls exactly when the switch from NREM to REM sleep can take place, and stress during the day disrupts its activity, leading to "disorganized sleep”

Summary

Trump’s nomination of Dave Weldon to lead the CDC, alongside Robert F. Kennedy Jr. as HHS secretary, raises concerns about U.S. vaccine policy.

Weldon, a former congressman and vocal vaccine safety critic, has pushed false claims linking vaccines to autism and sought to shift vaccine oversight away from the CDC.

Experts warn this leadership could undermine public trust in vaccines, disrupt the CDC’s immunization guidelines, and fracture state policies.

The stakes are high as the U.S. faces rising measles, whooping cough, and global health threats like H5N1 bird flu.

Seriously, the SMM Fandom is the world's closest thing to a utopia.

Ukraine’s President Zelenskyy reported nearly 500 drone attacks and over 20 missile strikes by Russia in the past week, calling it a “testing ground” for Russian weapons.

Russia launched 460 Shahed drones, produced in domestic factories, which, though cost-effective and easier to neutralize, strain Ukraine’s air defenses.

Recent attacks, including Russia’s use of the Oreshnik ballistic missile, escalate tensions.

Ukraine urges allies for more air defense systems, while debates over supplying Ukraine with long-range missiles and potential NATO membership intensify among Western nations.
