Psychedelics and immortality: Nature went to a health summit starring RFK and JD Vance The Make America Healthy Again summit, attended by health secretary Robert F. Kennedy Jr and vice-president JD Vance, gave a sense of what’s driving US health policy.

What it was like inside last week’s MAHA Summit, by @maxkozlov.bsky.social who was there:

The US government shutdown is over: what’s next for scientists Government researchers are heading back to work, but questions about the size of research-budget cuts will extend into next year.

After a bruising 42-day shutdown, the government has finally reopened. We took a look at what's next for federal scienceβ€”how quickly things will get back up to speed and whether there will be long-term consequences.

With Jeff Tollefson and @alexwitze.bsky.social:

What Rosalind Franklin truly contributed to the discovery of DNA’s structure Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

Getting Rosalind Franklin’s story right is crucial, because she has become a role model for women going into science

Dismantling of US federal agencies will β€˜destroy science’ From NASA to the National Institutes of Health, federal agencies conduct research that universities cannot. Agency scientists speak out about the irreplaceable facilities, institutional knowledge and ...

Reporter @virginiagewin.bsky.social interviewed 19 current and former US federal agency scientists about the science being dismantled at EPA, NOAA, NASA, CDC, NIH, & USGS.

They say it's making America unprepared for environmental and public health crises.
