In the mid-20th century, astronomers discovered strange “clumpy” galaxies filled with mysterious bright blobs – massive stellar nurseries where stars are born at an explosive rate. Curiously, these clumpy galaxies were much more common in the early universe than they are today. We still don’t know why they vanished. TheContinue Reading

Today, there are 94 nuclear reactors operating in the United States, more than in any other country in the world, and these units collectively provide nearly 20 percent of the nation’s electricity. That is a major accomplishment, according to Dean Price, but he believes that our country needs much moreContinue Reading
Hydrogen sits at the center of some of the world’s most important industrial processes, but its production still comes with a heavy environmental cost. Today, most hydrogen is produced through high-emissions processes like steam methane reforming and coal gasification. But hydrogen can also be made by splitting water molecules using renewableContinue Reading
A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules of genetics. Researchers discovered hundreds of cases where these chemical DNA marks behaved unexpectedly, including some that seemed to emerge out of nowhere. They also identified the first known naturallyContinue Reading
