Since ~ 2021, trans people have been subject to extensive political & media hysteria. For the crime of seeking to live freely, their motives have been impugned, their identities questioned, and their rights constrained. This "concern" has very real costs for trans people.

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

AI slop gracing the cover of Royal Society B. Not only in AI yellow but scientifically nonsensical. Come on. I'm certain human photographs and artworks were ignored to platform ... this.

Protoceratops in an ironstone enhanced burrow. The burrow had rolled down the hill. Most pics are of a Proto in burrow not enhanced by ironstone (no sign of burrow) scavenged beetle larvae, who left borings in the bone and their pupae. They loved to chew up the cartilage in the joints.

I remember hearing the words "brought to you by the corporation for public broadcasting" every time I watched Sesame Street as a kid. Horrifying that this tiny pot of funds for educational media and public information is being stolen from us. www.npr.org/2025/08/01/n...
Corporation for Public Broadcasting says it's shutting down
The Corporation for Public Broadcasting, which funnels federal money to public media stations, says it's winding down operations after President Trump signed a law rescinding all funding.

Dr. Karen Chin is a Professor & Curator of #Paleontology at UC Boulder, studying Mesozoic ecosystems/community interactions. A great mover and shaker in #coprolite science, we are excited to have her as an invited speaker at this year's @geosociety.bsky.social session T154. Coprolite Happens!

Swarthmore College has a teaching collection of fossil plants that has probably not been used in decades, recently re-discovered when we moved into a new building. We are hoping to catalog/digitize them. Can anyone ID any of these specimens beyond the brief descriptions on the cards? (1/2)

This is a hideous invasion of civil liberties
Le Monde reporting that a French scientist traveling to Houston to attend a conference was denied entry to US after a search of his phone & computer revealed messages critical of Trump's science cuts, "which [says CPB] conveyed hatred of Trump & could be qualified as terrorism".

Benjamin Franklin produced the very first chart of the Gulf Stream and then two more charts of it—here’s the final one, of 1786, showing Dr. Franklin in the lower right-hand corner, lecturing poor old Neptune, behind whom is the source of the Gulf Stream: the Gulf of Mexico

This is a nice discussion of stable isotope analysis with application to shark teeth. Remember, though, folks that this technique is used for lots of stuff

Fossil shark teeth are abundant and can date the past in a unique way
Sharks have ruled the Earth’s oceans for 400 million years. Recent research on fossil shark teeth has discovered an innovative method for dating ancient sediments.
