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

Sounds like a riddle written by a preschooler tripping on Pixie Stix and David Attenborough DVDs. But it’s actually the finding of… Continue reading These Invasive Ants Are Changing How Lions Hunt
Tight-Knit Microbes Live Together to Make a Vital Nutrient
In the radioactive bacteria, Tschitschko and his colleagues detected the Gamma A version of the nitrogenase gene. They were on its trail. However, the gene was located in an exotic genomic environment. When they sequenced the DNA of the Gamma A bacterium, most of its genome was typical of a globally distributed class of bacteria… Continue reading Tight-Knit Microbes Live Together to Make a Vital Nutrient
