Evolutionary adaptation to global change reduces sustainable fisheries yields Global warming is altering the fisheries that underpin food security, but projections of these impacts generally exclude evolutionary processes. We describe a model that forecasts how fish will adapt ...

Kansas revokes driver's licenses of hundreds of trans people, prompted by new law Prompted by a new law, Kansas began sending letters to some trans people saying their drivers licenses were being invalidated until they change their gender information.

๐Ÿšจhey so this is absolutely HORRIBLE for so many reasons I canโ€™t even fully list out. But a few:

- licenses are immediately invalid, making it difficult to even get around to change license or god forbid APPEAL THIS DECISION

Alex Jeffrey Pretti was an ICU nurse at a VA hospital. His life, through his profession, was dedicated to serving his community and our country.

As so many have now seen on video, his final act before he was killed by federal agents was doing everything in his power to protect his community.

Taxonomic differentiation of catch. FAO (United Nations Food and Agricultural Organization) on the percentage of catch reported to the species level worldwide.

Whatโ€™s driving the decline?

The crisis isnโ€™t just fishing โ€” itโ€™s invisible fishing.

Much shark & ray catch is under-reported, aggregated, or mislabeled, masking real mortality & delaying management.

What we donโ€™t measure, we donโ€™t manage.

Everywhere I look I see women leaving academia for one reason or another, and many of these reasons are less relevant to male counterparts. Obstacles like longer review times are certainly not helping, especially in a career where success and progress are measured in publications!
