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
Tyrannosaur’s Stomach Contents Have Been Found for the First Time
For the first time, scientists have unearthed direct proof of what a tyrannosaur—often thought of as the epitome of fearsome predators—actually ate. The fossilized stomach contents of one member of this dinosaur family were described in a new study published on Friday in Science Advances. This remarkable discovery gives insights into the tyrannosaur diet and… Continue reading Tyrannosaur’s Stomach Contents Have Been Found for the First Time
The ‘Accidental Activist’ Who Changed the Face of Mathematics
Lenore Blum’s long career has spanned the breadth of mathematics and computer science. She’s done influential work in logic and cryptography, and she formulated an entirely new model of computation. And though she didn’t set out to do so, she’s also devoted a significant chunk of her time to building institutions to help women follow… Continue reading The ‘Accidental Activist’ Who Changed the Face of Mathematics
Deep Beneath Earth’s Surface, Clues to Life’s Origins
At most, Lang expected to find trace amounts of hydrogen so far underground. But the deepest water sample contained so much gas that as it surfaced, bubbles formed in the tube, a phenomenon similar to what happens when you crack open a fresh can of soda. “We were like, holy crap,” Lang said, recalling her… Continue reading Deep Beneath Earth’s Surface, Clues to Life’s Origins
