Wow, I just found out that our team has been scooped by Anthropic www.anthropic.com/research/yes... See the addendum of the post “How does it feel to be scooped by a machine?” written by my collaborator Lance Dixon (who was under NDA while checking the result)

RIP Dolly Parton. There are so many wonderful things to remember her for, but the one I like to bring up is all the work she did for childhood literacy. Probably its greatest advocate in our lifetimes. God bless Dolly Parton.

People in the coffee world will usually give you the recommendations for better coffee as: 1. Buy good quality coffee. 2. Buy the best grinder you can afford. but I think an often unsaid 0th recommendation is to clean your equipment thoroughly and regularly.

New: The National Science Foundation is preparing to claw back some $500 million in funds from some of its core science programs in physics, math, computer science, and engineering in order to fund a project from the White House Office of Science and Technology Policy.

Not true. In their list of grievances, the Founding Fathers complained that King George III was blocking colonial laws that would promote immigration and make it easier for foreign settlers to become citizens.
Reuters tweeted: "Pope Leo urged Americans to uphold the ideals of the Declaration of Independence, praising the country's long tradition of welcoming immigrants in his first major address to the United States." They then attached a video of the Pope speaking. 

Someone named NoraNH replied: "The Declaration of Independence doesn’t mention immigrants"The Declaration of Independence.He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.

Thanks to Trump's tax cuts, 88 corporations — including Coinbase, CVS, and Disney — paid ZERO federal income tax last year. They also spent $852M on political donations and lobbying. Their combined tax savings: over $26 BILLION (a 3,000% ROI!) We must break this corrupt cycle.

tl,dr; Scientists no longer allowed to use federal funding to publish, attend meetings, or talk to the public. They cannot collaborate internationally. Grants can be cancelled for any reason, at any time, political appointees have a final say over what gets funded, and who gets funded.
