Making stars is a messy business. Although the process takes far longer than any human life span, we’ve sufficiently studied its various stages in stellar nurseries scattered around our galaxy to gain a decent overall grasp of how it works. It starts, in general, with a huge swirling cloud of gas and cosmic dust—like the… Continue reading Astronomers Spy First Star-Forming Disk beyond the Milky Way

Bad Science and Bad Statistics in the Courtroom Convict Innocent People
The city of New York recently witnessed a record payout to George Bell, falsely convicted of murder in 1999, after it emerged prosecutors had deliberately hidden evidence casting doubt on his guilt, giving false statements in court. Bell is the latest in a long line of people, especially Black Americans, unfoundedly convicted. More recently, Jabar… Continue reading Bad Science and Bad Statistics in the Courtroom Convict Innocent People
How to Choose an Environmentally Friendly Christmas Tree
The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Every year, Americans buy somewhere between 35 million and 50 million Christmas trees, and many more pull an artificial tree out of storage for the season. In all, about three-quarters of U.S. households typically have some kind of Christmas… Continue reading How to Choose an Environmentally Friendly Christmas Tree
‘Magical’ Error Correction Scheme Proved Inherently Inefficient
Unfortunately, the Reed-Muller code has a serious drawback: The number of bits required to encode a message increases exponentially with the number of variables. If you want a highly local code that corrects errors with just a handful of queries, you’ll need a lot of variables for long messages, and the Reed-Muller code will quickly… Continue reading ‘Magical’ Error Correction Scheme Proved Inherently Inefficient

New Kind of Magnetism Spotted in an Engineered Material
All the magnets you have ever interacted with, such as the tchotchkes stuck to your refrigerator door, are magnetic for the same reason. But what if there were another, stranger way to make a material magnetic? In 1966, the Japanese physicist Yosuke Nagaoka conceived of a type of magnetism produced by a seemingly unnatural dance… Continue reading New Kind of Magnetism Spotted in an Engineered Material
AI Can Now Read Your Cat’s Pain
Sophie Bushwick: Can you tell what a cat is thinking, just from looking at it? Tulika Bose: Probably not! Cats evolved to be solitary hunters stalking their prey, not social animals like us humans. Bushwick: And that poker face might be handy while you’re out stalking prey, but it’s a real problem if humans are… Continue reading AI Can Now Read Your Cat’s Pain
The Theorist Who Sees Math in Art, Music and Writing
After a while, my set of pictures started to look like a particular set of graphs that were listed in a book about Coxeter groups that was in my office, and I began to hope that it was this exact set of graphs. If it was, then that would fill in the hole in my… Continue reading The Theorist Who Sees Math in Art, Music and Writing
Evolution: Fast or Slow? Lizards Help Resolve a Paradox.
Over time, however, that variability averaged out into stasis. Even if traits wobbled off their optimal, moderate peak from one generation to the next, there was a net effect of stabilization — ultimately leading to little change over the multiple generations. Experts who reviewed Stroud and his team’s data were impressed by its thoroughness and… Continue reading Evolution: Fast or Slow? Lizards Help Resolve a Paradox.
FDA Approves First CRISPR Gene Editing Treatment for Sickle Cell Disease
CRISPR, the gene-editing technology that has revolutionized biological research, is finally available as a medical treatment with regulatory approval. On December 8 the U.S. Food and Drug Administration approved the first CRISPR treatment for sickle cell disease. The treatment, called exa-cel and made by the companies Vertex and CRISPR Therapeutics, edits a gene involved in… Continue reading FDA Approves First CRISPR Gene Editing Treatment for Sickle Cell Disease
