2) Shutting down 8 irMS in preparation and doing routine maintenance with the forced downtime...

Well, there is the gall to explicitly tell researchers not to use AI for peer review while the publishers upload every draft that we submit to their in house AI for "extraction purposes"... Effectively building training databases off of unpublished works with no possibility for opt out.

Recovery of Paleodictyon patterns after simulated mining activity on Pacific nodule fields - Marine Biodiversity Since the late 1980s, various experiments have been conducted in polymetallic nodule fields of the Pacific Ocean to assess the potential environmental impacts of future mining, specifically in two are...

This is one of the wildest deep-sea mining stories to me.

Paleodictyon is a 500-million-year-old trace fossil from an unknown organism. In the last 50 years, we've found their honeycomb traces on the seafloor. There is a living organism that has been doing its thing for half a billion years.

Trump administration plans to break up largest federal climate research center Russ Vought, director of the White House Office of Management and Budget, said the National Science Foundation "will be breaking up" the National Center for Atmospheric Research in Colorado.

β€œNCAR has played a greater role in advancing weather prediction & atmospheric modeling than perhaps any other single entity in the world,” says @weatherwest.bsky.social

Dismantling NCAR would be β€œlike taking a sledgehammer to the keystone holding up our scientific understanding of the planet.” KH

Experimental design for the well replicated parasite-host feeding study. 4 time periods, 3 tissues, host and parasite makes bulk sampling difficult and amino acid sampling excessively expensive and labor intensive! Great work by first author!

🧬 New study teases apart how parasites β€œtap into” host metabolism using nitrogen isotope profiling. A cestode parasite shows just ~0.5 ‰ trophic shift from its host’s liverβ€”revealing surprisingly direct nutrient assimilation.

Trump’s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives U.S. productivity growth β€” and pays for itself

Every R and D dollar spent returns 1.40 to 2.10 since 1946. Slashing research funding is short sighted and needs to account for the long term losses in economic output that these actions have.

Chapter 16 is where the stable isotopes are in case you were wondering! It's a good resource for parasitologists who may be interested in applying SI techniques to parasite-host relationships.

βœ… Standardised protocol for global comparisons
βœ… 586 new host-parasite pairs
βœ… Carbon, nitrogen and sulphur stable isotope values
βœ… Doubling existing data, tripling δ³⁴S records
