Disruption of global research at NIH is endangering people in the United States and around the world. 27unihted.substack.com/p/disruption... Foreign collaborations have been interrupted and discouraged and foreign scientists in the United States are working in an increasingly hostile environment.

So (if I understand this correctly), the way AI (companies) will "solve" all the major problems in maths, biology, and medicine in the next 5 years will be by stealing and building on the ideas of researchers naive enough to think their chats with AI companies would be private.

407 years ago, on the 20th of August 1619, the first enslaved Africans were brought to the British Colonies in North America. This is seen as the starting point for African American history. The enslaved were taken from the Kingdom of Ndongo. #otd #history 🗃️
A historical marker sign notes the arrival of the first Africans in English North America.

First Africans in Virginia

The first documented Africans in Virginia arrived in 1619 when a Dutch warship landed here at Point Comfort. The “twenty and odd” Africans, captured from the Spanish, were traded to the Virginia colonists in exchange for foodstuffs. Early Africans who lived here included Antony and Isabell, and their son William, likely the first black child in present-day Hampton. They served Point Comfort Commander William Tucker, but whether the early Africans were treated as indentured servants or slaves is uncertain. The institution of slavery evolved during the 17th century as the term of service for Africans was extended for life. The U.S. abolished slavery in 1863.

Paleogenomics research is revealing the complex history of bison, overturning assumptions about the ubiquity of cattle ancestry and showing that their decline did not markedly affect genetic diversity, although it has increased population fragmentation. Read more in Science: scim.ag/4wekKWJ
Wood bison such as this one, photographed near Muncho Lake Provincial Park in Canada’s Northern Rockies, split from plains bison ~3000 years ago but have plains ancestry from early 20th-century management. Paleogenomics research is revealing the complex history of bison, overturning assumptions about the ubiquity of cattle ancestry and showing that their decline did not markedly affect genetic diversity, although it has increased population fragmentation. An accompanying news feature explores how genomic findings are guiding conservation.
