The Centers for Disease Control and Prevention says a glitch in its bird flu test hasn’t harmed the agency’s outbreak response. But it has ignited scrutiny of its go-it-alone approach in testing for emerging pathogens. The agency has quietly worked since April to resolve a nagging issue with the test it developed, even as the… Continue reading The CDC’s Test for Bird Flu Works, but It Has Issues

What Are Sheaves? | Quanta Magazine
In 1940, the French mathematician and artillery officer Jean Leray was taken prisoner by the Germans. He told his captors that he was a topologist, fearful that if they discovered his true area of expertise, hydrodynamics, they would force him to aid the German war effort. For the nearly five years of his imprisonment, Leray… Continue reading What Are Sheaves? | Quanta Magazine
Signs of Ancient Alien Life May Lurk within This Newfound Martian Rock
In a dry river valley on Mars, NASA’s Perseverance rover may at last have found its reason for being: evidence of ancient alien life—and with it, a lifeline for the space agency’s grand but troubled plan to bring Red Planet materials to Earth. This potentially cosmos-quaking evidence may look like merely a humble rock, but… Continue reading Signs of Ancient Alien Life May Lurk within This Newfound Martian Rock
Monumental Proof Settles Geometric Langlands Conjecture
In classical signal processing, sound waves get built up out of sine waves whose frequencies correspond to the pitches contained in the sound. It’s not enough to know which pitches the sound contains — you must also know how loud each pitch is. That information allows you to write your sound as a combination of… Continue reading Monumental Proof Settles Geometric Langlands Conjecture
Vacuum of Space to Decay Sooner Than Expected (but Still Not Soon)
Vacuum decay, a process that could end the universe as we know it, may happen 10,000 times sooner than expected. Fortunately, it still won’t happen for a very, very long time. When physicists speak of “the vacuum,” the term sounds as though it refers to empty space, and in a sense it does. More specifically,… Continue reading Vacuum of Space to Decay Sooner Than Expected (but Still Not Soon)
Musical Memories Don’t Fade with Age
Musical Memories Don’t Fade with Age Eighty-year-olds are able to identify familiar tunes just as well as teenagers can By Bianca Nogrady & Nature magazine Musical memory might be resistant to age-related cognitive declines because it stirs emotions and becomes more encoded in memory. The ability to remember and recognize a musical theme does not… Continue reading Musical Memories Don’t Fade with Age
NASA’s Hopes for Space Solar Power Are Looking Dim
The sun may be setting on NASA’s plans to build a space-based solar power (SBSP) satellite system to alleviate our energy needs on Earth. In January, the agency released a report that, citing launch costs specifically, concludes that generating power from orbit is simply too expensive, especially compared with solar power made right here on… Continue reading NASA’s Hopes for Space Solar Power Are Looking Dim
How Arguments that Embryos Are People Pose a Threat to IVF
On February 16 the Alabama Supreme Court brought fertility care in that state to a screeching halt—and started a national conversation—by declaring that frozen embryos were people in the eyes of the law. In support of its decision, the court cited a 19th-century Alabama statute, the state’s constitution and, in a memorable concurrence from Chief… Continue reading How Arguments that Embryos Are People Pose a Threat to IVF
The Physics of Cold Water May Have Jump-Started Complex Life
Modern-day algae are not early animals. But the fact that these physical pressures forced a unicellular creature into an alternate way of life that was hard to reverse feels quite powerful, Simpson said. He suspects that if scientists explore the idea that when organisms are very small, viscosity dominates their existence, we could learn something… Continue reading The Physics of Cold Water May Have Jump-Started Complex Life
Paying Attention to Sensations Can Help Reset the Mind
Having grown up in the Danish city of Copenhagen, chef René Redzepi recalls feeling dissatisfied with the fast-food world to which many city-dwellers were accustomed. He instead attributes his love for food to his summers in Macedonia, which were filled with farm life and foraging in the nearby woods. Despite the lack of technological sophistication,… Continue reading Paying Attention to Sensations Can Help Reset the Mind
