White House blasts Nobel Committee for not awarding Peace Prize to Trump A spokesman says the Nobel Committee placed "politics over peace" in awarding the coveted award to Venezuela's opposition leader.

Advice to Trump: Violent tantrums, & letters of rec from Netanyahu, will not win you this prize. Good thing still happen in this world.

Big U.S. West Coast earthquakes could come as a one-two punch Cascadia and San Andreas fault zones appear to generate synchronized earthquakes

"A request for comment from the U.S. Geological Survey, which is responsible for monitoring seismic hazards on the West Coast, resulted in an automatic reply stating no one could respond because of the ongoing government shutdown."

He is brown and speaks Spanish. His legal status has nothing to do with a policy driven purely by bigotry racism and xenophobia. These are not mistakes.

Reminder. Fretting about escalators? We live in a Western world; powers are Western, pro-Western (money & weapons), or anti-Western (so-called new world order). The majority couldn't care less, but is forced to. There is wisdom in the majority. I am proud to be Caribbean.

Trump expands 'woke' criticism from Smithsonian to other museums "The Museums throughout Washington, but all over the Country are, essentially, the last remaining segment of "WOKE," he wrote.

A #FossilFriday visual treat, the Cretaceous diatom Trinacria nitescens. In addition to their global ecological importance, diatoms are also a visual feast. Staring at this one enough will do wonder for your eyes. Scale bar = 10 microns. #paleontology @calacademy.bsky.social flic.kr/p/8cy7X6

This #FossilFriday we have a fish. An unidentified fish. Early Cretaceous from Rio Grande do Sul, Brazil. So many fossils, so few names, so few taxonomists. The dark data of paleo and Earth's missing diversity. All suggestions are welcome! #paleontology @calacademy.bsky.social flic.kr/p/7yP95M

#FossilFriday trilobite Zacanthoides idahoensis! Great name. An early carnivore from the Middle Cambrian of Utah. #paleontology collections @calacademy.bsky.social flic.kr/p/7v2AFP

Happy #FossilFriday ammonite. Acanthohoplites barryana, from the Cretaceous of Shasta Co., California. #paleontology collections @calacademy.bsky.social flic.kr/p/Yx4fie

Fossils found on island are far older than island itself. How? The ancient Romans The marine fossils found on a Moroccan island are estimated to be between 145 and 140 million years old.

Ancient paleontologists or magical brachiopods?!

He gutted the intelligence networks, dismantled the anti terrorism task force, has the FBI working on deportations while headed by an imbecile, and then bombed Iran. Do all the miserable morons who voted for and support him feel safer today? I don't.

Here we go again America. Supporting warmongering and bombing the Middle East. Old habits die hard; easier to kill people apparently.

For #FossilFriday we celebrate Los Angeles w/ the round slipper snail, holotype of Crepipatella charybdis, from the Pleistocene of Los Angeles Co., California. Og genus Verticumbo (rev. J. McClean), still a part of California's great diversity. #paleontology @calacademy.bsky.social flic.kr/p/fmfhE7

#FossilFriday clam. Venericardia merriami holotype, Oregon, USA. From the Eocene, shortly before the planet changed, transitioning from a Warm House to the Cool/Ice House planet that we currently have (for now). #paleontology @calacademy.bsky.social flic.kr/p/pUwnwu

#FossilFriday foram! Vaginulinopsis verruculosa, Eocene Lodo Fm. of California. The Lodo records the Paleocene-Eocene Thermal Maximum when global average temp. rose more than 5 C, lasting ~200,00 years! A time of big biotic change. #paleontology #foraminifera @calacademy.bsky.social flic.kr/p/rBMU4y

Attorney General Bonta Sues to Stop Termination, Withholding of National Science Foundation Grants OAKLAND – California Attorney General Rob Bonta today filed a lawsuit to stop the U.S. National Science Foundation (NSF) from: (1) terminating grants for scientific research that seeks to promote and understand diversity in higher education and the workforce, and (2) imposing a 15% cap on indirect cost reimbursements for research projects.

Trump team pauses new student visa interviews as it weighs expanding social media vetting It’s the latest salvo against universities, many of whom rely heavily on foreign students for funds.

Subjecting international students to more extreme social media vetting so they can study in the U.S. will only further chill free speech on campus.

The Trump administration must not double down on this discredited and discriminatory approach.

‘Science saved my life’ — and it must save other at-risk scholars The global scientific community must do more to offer safety and support to displaced academics and others.

“The protection of at-risk scholars is not just a moral duty — it is an investment in science itself.” Our community needs to define and recognize who among us needs help, and organize ourselves to do whatever we can. There is no one coming to the rescue until we act. www.nature.com/articles/d41...

Are Humans Apex Predators?

(Oceana.org) In 2013, Sylvain Bonhommeau and colleagues published a study (Eating up the world’s food web and the human trophic level) in which they defined a Human Trophic Level (HTL). It’s a very neat study, in which the researchers examined human diets globally, with…

It's #FossilFriday! Holotype of the Pleistocene diatom Rouxia leventerae, McMurdo Sound, Antarctica. Scale bar=10 um! Diatoms produce up to 50% of Earth's oxygen each year. They remind us that small can be mighty, and of the power of numbers. #paleontology @calacademy.bsky.social flic.kr/p/dT1BWa
