Busted Remember all those celebrities who took money from crypto companies to do ads encouraging low-information dupes into investing? They're still rich, but they've been awfully quiet since the industry they shilled has tanked in value . As The New York Times notes , not a single one of the celebrities who did cryptocurrency ads earlier this year has said anything since its cumulative valuation
The extraordinary leak of a draft Supreme Court opinion overruling Roe v. Wade has reignited a discussion about ethical responsibility in public life. The core concern of ethics is that, in deciding what to say and how to act, those with public roles must look to the public's interests, not their own or those of a narrow class of allies. In a period of acute concern about the erosion of instituti
Hamster Brawl Scientists say that a little gene hacking turned adorable hamsters into vicious monstrosities. Researchers at Georgia State University may have published the scientific understatement of the year when saying that their CRISPR experiment with hamsters "found that the biology behind social behavior may be more complex than previously thought."

Back in 1981, Cameron Gordon introduced a new way to relate two knots — mathematical constructs modeled after the knots that appear in a single thread or string. In his paper, he conjectured that this new relationship could be used to arrange groups of knots according to how complicated they are. This winter, Ian Agol, a mathematician at the University of California, Berkeley, posted a six-page..
For weeks now , as COVID-19 cases have ticked upward in the Northeast and mid-Atlantic, pundits and political leaders have offered a supposedly reassuring refrain: Cases might be climbing, but hospitalizations aren't yet following suit. In some places, that has been true. Several health-care workers around the country told me they're seeing the lowest caseloads since last summer. A few aren't hav
Even if you don't know a single policy he supports, chances are good that you know what John Fetterman looks like. Pennsylvania's lieutenant governor is larger than life at 6 foot 8, distinctively bald with a salt-and-pepper goatee, and draped in a baggy shirt or hoodie. Oh, and he's a shorts guy too. Fetterman easily won today's Democratic primary for U.S. Senate, and will run in November in a r
The end of NASA's InSight Mars lander is, well, in sight. The spacecraft has long been battling with Martian dust obstructing its umbrella-shaped solar panels, making it increasingly difficult to charge its batteries. Now, in a Tuesday update , NASA revealed that Insight's science operations are coming to a close later this summer. By December, they say, the lander will have "become inoperative."

Updated at 6:10 p.m. ET on May 18, 2022 "What do you think of this company Netscape ?" my parents asked. It was 1995, and they had called me on the landline, which back then just meant the telephone. Netscape was a company that made a graphical web browser— the web browser, really—but gave it away for free. Its income statement showed only modest revenue (and substantial losses). The web was new
Three years ago, when a white-supremacist fanatic killed dozens of people in El Paso, Texas, the reaction from the right was unreserved condemnation . When another white-supremacist fanatic killed 10 people at a supermarket in a Black neighborhood in Buffalo, New York, last week, the reaction from some figures on the right was to acknowledge that the guy had a point about this whole "replacement"

To hold his Senate seat against his challenger, Beto O'Rourke, in 2018, Ted Cruz spent nearly $40 million. O'Rourke's campaign spent double that amount. The day before the vote in Texas, Cruz lent his campaign $260,000. This was a curious—and seemingly unnecessary—gesture: The campaign's final report showed it ended with $263,000 cash in hand. Yet Cruz was not acting irrationally. He was preparin
These days, almost all of us feel pressed for time. Leadership expert Dorie Clark shares three hidden reasons people fall into an endless loop of feeling constantly busy, and invites you to question what really motivates how you spend your time.
"The idea is if we don't look out the white race will be—will be utterly submerged. It's all scientific stuff; it's been proved." These are not the words of the teenager who walked into a supermarket in Buffalo, New York, on Saturday to hunt down Black Americans, although they might as well be. These are the words of Tom Buchanan, a rich, repugnant character in the 1925 novel The Great Gatsby.
Clam-iroquai Just like your average EDM fan, scallops can, as it turns out, be captured more easily when you turn on the pretty lights for them. As The Guardian reports , a group of fishing consultants (yes, that's a thing) have devised a devious plot to lure unsuspecting scallops — by flashing "disco" lights inside trap baskets, which apparently attracts them.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
