In the arms race of life, a number of animals use venom as a weapon to paralyze prey and jump-start digestion. Meanwhile, venom also helps a variety of other seemingly defenseless creatures improve their odds against larger, stronger or more aggressive foes. In Venomous, molecular biologist Christie Wilcox surveys the animal kingdom’s wide array of […]

Here’s something new for real estate agents to boast about in posh neighborhoods: houses with a bigger variety of insects and spiders. Maybe that’s not the best selling point. But what’s called a “luxury effect” appeared among more than 10,000 arthropod samples collected from the insides of 50 houses in urban and suburban Raleigh, N.C. […]

It’s all relativeIn “Earth is young at heart” (SN: 6/25/16, p. 5), Emily Conover reported that Earth’s core is more than two years younger than the planet’s surface, according to new calculations. Thanks to the effect of gravity on the passage of time, a clock placed at Earth’s core will tick fractions of a second […]

It’s time to go wild studying antimicrobial resistance, a research team says. Most analyses of how microbes come to laugh off the drugs and disinfectants that should kill them have focused on people in hospitals or livestock on farms, says behavioral ecologist Kathryn Arnold of the University of York in England. Yet a growing number […]

Out-of-reach nutrients could help explain why life on Earth took so long to bounce back from the worst extinction of all time. Analyzing the chemical changes that followed the Permian extinction 252 million years ago, geologists propose that hot sea surface temperatures led to conditions that trapped nitrogen far below the ocean’s sunlit, life-filled layers. […]

If you have an appetite for cosmic destruction, there’s an app for that. NOVA Black Holes, a free iPad game developed by the PBS series NOVA, lets you hurl a star at other celestial objects while navigating an increasingly complex minefield of stars, planets and black holes. Each level presents a new target and a […]

Call it exoplanet fatigue. The historic detection of an exoplanet just 4.2 light-years from Earth, featured on our cover, was big news. It attracted a lot of media buzz. But outside the office, I heard little about it. No questions from other parents at the playground, including those who had been eager to chat about […]

A Swedish scientist is gene editing healthy human embryos, and he is probably not alone, researchers say. Chinese researchers have twice reported editing genes in human embryos that are unable to develop into a baby (SN Online: 4/6/16; SN Online: 4/23/15). But developmental biologist Fredrik Lanner of the Karolinska Institute in Stockholm is the first […]

Rosetta is no more. The comet orbiter touched down on the surface of comet 67P/Churyumov–Gerasimenko at 7:19 a.m. Eastern and immediately shut down, bringing to an end a nearly 26-month mission in orbit around the comet. “I hereby declare mission operations ended,” said Rosetta mission manager Patrick Martin. The landing site has been dubbed Sais, […]

Bagels and pretzels have a lot in common with the physics of certain materials: The snacks illustrated the mathematics behind theoretical descriptions of exotic states of matter, work which won the 2016 Nobel Prize in physics on October 4. David Thouless of the University of Washington in Seattle, J. Michael Kosterlitz of Brown University and […]
