BREAKING: Scientists are staging a “science fair” in the lobby of a Congressional building to tell elected officials about the critical knowledge the US will lose because their research grants have been canceled.

‘Biodiversity is not declining’ is a claim you may have heard. But science says otherwise. 📉 The @ipbes.net #GlobalAssessment reveals 1 million plant & animal species are at risk of extinction. Misinformation clouds the crisis. Rely on trusted research to understand our shared challenges. 🌍🧪
A split-screen image. The left side shows a rhinoceros mother and calf in a savanna landscape with scattered trees. The right side depicts a forest fire scene with orange flames and silhouetted trees against a dark sky.
Text reads:
"Biodiversity is in crisis" followed by:
"1 million plant and animal species risk extinction
Ecosystems are collapsing
Misinformation slows progress." 
"Trust the science.
Conserve, restore and sustainably use biodiversity."

Final vote. 50-50. VP breaks the tie. One single GOP Senator could have stopped this abomination. Saved millions of parents from watching their child go hungry. Saved the lives destroyed when Medicaid disappears. They will all live forever with the horror of this bill.

Today marks a special anniversary for us. On July 1, 1858, the theory of evolution by natural selection was first presented at a Linnean Society meeting. Papers written by Charles Darwin & Alfred Russel Wallace were read, shaping a groundbreaking idea still powering science today: buff.ly/uBdX7N1
“On the tendency of Species to form Varieties” paper by Wallace and Darwin originally published in the Journal of the Linnean Society of London, Zoology. Read on 1st July 1858 at the Society. Portrait of Darwin (1809-1882) commissioned by the Society in 1883 which can be found in the Society’s Meeting Room. Portrait of Alfred Russel Wallace (1823-1913).

The latest @dev-journal.bsky.social poster on stem cell-based models of early human development is proving popular at #ISSCR2025. Come and get your free copy at stand 911 before they are gone.
Scientific poster from the journal Development, with the title Stem cell-based models of early human development. It provides a brief summary of recent human post-implantation stem cell-based embryo models, focusing primarily on models that capture the peri-gastrulation, compared with corresponding  in-vivo developmental processes.

VP Vance has cast the deciding vote in the Senate to cut Medicaid, take away food assistance, blow up the deficit, and add tax breaks for the wealthiest. This bill is unpopular because it is wrong. Congress votes this week, but it’s our voices - and our votes - that will have the final say.
