It took nearly a decade for most archaeologists to come around to the idea, but Monte Verde rewrote the story we thought we knew about how (and when) people first moved into, and spread throughout, the Americas. For once in the history of science, that statement isn’t just a headline-grabbing exaggeration—it was really that big ..

Despite being declared the third-hottest year on record, 2025 was a relatively quiet year for climate disasters in the US. No major hurricanes made landfall, while the total number of acres burned in wildfires last year—a way of measuring the intensity of wildfire season—fell below the 10-year average. But starting this week, the West is experiencing what looks to be a ..
There was no commercial application for the P-51. The P-51 was there to be a fighter escort and sweep asset for air superiority missions. As operational concepts mature for space superiority, those operational concepts will drive a performance envelope for warfare that will be mutually exclusive of commercial applications. Not in all cases. There are ..
In the US, the economics of coal power generation are marginal at best, and a large number of coal plants have shut down as cheaper renewables and natural gas have surged. The Trump administration has used a number of methods to swim against this economic tide, the simplest of which has been to order plants ..
Birch tar had no effect on the E. coli cultures, but it did stop, or at least slow down, the growth of S. aureus. Exactly how well depended on the species of birch and the concentration of the tar, probably because different birch species, and maybe even individual trees, produce tar with different combinations of ..
The suit also alleges that this is part of a pattern of attacks on Colorado. Earlier in 2025, the US government moved a major Space Command facility from Colorado to Alabama. “When issuing his decision,” the suit continues, “the President stated that ‘the problem I have with Colorado’ is that ‘they do mail-in voting’ and ..
The attorneys general requested a response by March 2, one that addresses a set of leading questions, such as, “Why did the National Academies include a chapter on climate science that is not based on balanced or sound science?” and “What procedures will the National Academies establish to prevent similar advocacy-based chapters in future editions?” ..
The team found that even a small number of interacting males can synchronize their flashes, but the periodic bursts only happen in groups larger than 15. And the flashes are correlated over several meters, evidence of long-range interactions typical of emergent collective behavior. But Peleg et al. also noted some individual trajectories, suggesting that there ..
In Nim, there is a limited number of optimal moves for a given board configuration. If you don’t play one of them, then you essentially cede control to your opponent, who can go on to win if they play nothing but optimal moves. And again, the optimal moves can be identified by evaluating a mathematical ..
The solution to the strange flickering problem came when the Liverpool Gravitational Wave Optical Transient Observer collaboration detected an object designated SN 2024afav on December 12, 2024. Initially, the object looked like a standard superluminous supernova. “It was as bright and it had bumps in the light curve like many other objects of this kind,” ..
