Read my review of John Long’s book The Secret History of Sharks in @currentbiology.bsky.social

A fascinating read about the deep history of sharks, the scientists who study them, and the adventures they have in the quest to learn more.

The ocean gives us food, oxygen, livelihoods, and climate regulation.
But it’s under threat from overfishing, climate change, pollution, and habitat loss.

When our ocean is in crisis, so are we.
Protecting it means protecting life itself.

Did you know that there's a whole treaty dedicated to migratory animals, such as whales, birds, and butterflies?

The @cms.int is the only international convention specialising in the conservation and sustainable use of migratory animals and their habitats.

New paper led by @seaprinceaaron.bsky.social in @currentbiology.bsky.social looking at the threats deep sea mining poses for sharks, rays, and chimaeras. We found 30 species are threatened via various pathways including collector impact and plumes at depth and pelagic discharge plumes.
Figure 1: highlighting various pathways through which mining can impact sharks, rays, and chimaeras including collector impact and plumes, and discharge plumes. Figure 2: The diversity of sharks, rays, and chimaeras impacted by deep sea mining operations. Nearly 2/3 of these species are already at an elevated risk of extinction.

I am not anti-fishing.

I am not anti- shark fishing.

But hammerheads in particular are species of significant conservation concern, and one of the worst candidates for “catch and release” of any known fish species.

And it’d be nice if media coverage *of hammerhead fishing* mentioned that

It’s truly baffling to me that so many of these stories focus on “wow big fish” and not “this is an IUCN Red List Critically Endangered species that is extremely physiologically fragile and often does not survive fishing practices like this”

NEW: Nature trained AI to predict which NIH grants from 2014 would have been cut if the Trump admin had its way back then — and what science would have been lost to history.

"The results show the damage that cuts in funding can do to research, and the unpredictable nature of the research process."

We used machine-learning tools in an attempt to recreate the method for cutting funding, and then applied it to past US NIH grants to reveal the broad-reaching consequences
