America has already lost its global competitive edge in science, and funding cuts proposed in early 2025 may further a precipitous decline. Proposed cuts to the federal agencies that fund scientific research could undercut America’s global competitiveness, with negative impacts on the economy and the ability to attract and train the next generation of researchers. I’m an astronomer, and … Read more
A popular model of evolution concludes that it was incredibly unlikely for humanity to evolve on Earth, and that extraterrestrial intelligence is vanishingly rare. But as experts on the entangled history of life and our planet, we propose that the coevolution of life and Earth’s surface environment may have unfolded in a way that makes the evolutionary … Read more

Eighty million years ago humans, rats, and mice shared the same mammalian ancestor. More recently, researchers made the astonishing discovery that even today our genomes contain close to 500 segments that have remained totally unchanged since then. These segments are called ultra-conserved elements (UCEs). Nearly all the UCEs are also highly unchanged in the chicken … Read more
