Evidence for Hadean mafic intrusions in the Nuvvuagittuq Greenstone Belt, Canada Many questions remain regarding Earth’s earliest crust owing to the rarity of Hadean (>4.03 billion-year-old) rocks and minerals. The Nuvvuagittuq Greenstone Belt (NGB) in Canada may be the only known...

The Nuvvuagittuq Greenstone Belt— a complex geological sequence in northeastern Canada—harbors surviving fragments of Earth’s oldest crust, dating back to ~4.16 billion years old, according to a new Science study.

High UK visa costs deter international scientists and engineers It took Ed Roberts over a year to find a senior scientist to work at his cancer research laboratory in Scotland, a delay he blames on high UK visa costs that made it harder to attract international workers.

Skin damage signals mediate allergic sensitization to spatially unlinked antigen Skin injury releases damage-encoded systemic signals that can initiate immunity to novel antigens introduced at distal barrier sites.

#LocationLocationLocation! Wang Eisenstein Waizman @yaleschoolofmed.bsky.social &co show @ Science Immunology that physical, chemical, & radiation skin damage induces IL33 activating ILC2 & transferring to distal barrier tissues the capacity to induce antibodies causing #allergic responses!

75% of US scientists who answered Nature poll consider leaving More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.

We polled Nature readers to ask if they were thinking of leaving the US for jobs abroad. Three-quarters of them (who said they were US-based scientists) said yes. 🧪

A Decade of Cuts in a Matter of Days The Trump administration’s rapid terminations of NIH grants is its most aggressive attempt yet to control American science.

NIH officials were told this morning that approximately 1,000 more grants would be targeted for termination www.theatlantic.com/health/archi...

‘My career is over’: Columbia University scientists hit hard by Trump team’s cuts The US government has begun slashing US$400 million in research grants at Columbia University over pro-Palestinian campus protests.

🚨This week, many Columbia scientists lost grants that funded over half their annual income. Others will no longer be able to do research that helps treat thousands of sick patients across the US.

"It hurts," they told me.

My story for @nature.com 🧪

www.nature.com/articles/d41...

It is shocking and saddening to see how the two former global science powerhouses, USA and UK are collapsing in front of our eyes. For different reasons, but ultimately it’s about politics in both cases.

Happy #InternationalWomensDay2025 from a PI with an all-female team of fantastic scientists 🇫🇷🇸🇦🇮🇹🇬🇷

Vesuvius volcano turned this brain to glass The brain of a man who died nearly 2000 years ago was turned to glass by extreme conditions during the eruption of Mount Vesuvius. Researchers studied the strange material found in the man’s skull and spine and deduced the presence of a super-heated ash cloud that would have caused the tissue to first liquify then rapidly cool into glass - a unique event that has even preserved some brain structures.

Trump 2.0: an assault on science anywhere is an assault on science everywhere US President Donald Trump is taking a wrecking ball to science and to international institutions. The global research community must take a stand against these attacks.

We at Nature denounce this assault on science 🧪 www.nature.com/articles/d41...

Are PhDs losing their lustre? Why fewer students are enrolling in doctoral degrees High living costs paired with stagnant stipends are being blamed for a drop in PhD enrolments in several countries.

Cardiff University to cut 400 staff and drop subjects including nursing and music Union describe reductions as ‘cruel’ as university says it will run out of money without changes

Sorry to hear this about @cardiffuni.bsky.social
Losing 400 faculty means Cardiff Uni is now mostly employing administrators (they currently have 3660 admin to 3410) academics according to their website). At what point do you stop being an academic institution? www.theguardian.com/education/20...
