1. As seismic waves from earthquakes pass through the planet, their patterns can reveal hidden dynamics—hotspots, deep-diving rock, melting mantle—in Earth’s interior. An array of seismometers that’s being installed across the United States is now allowing geophysicists to plot revelatory views of the Earth engine deep beneath our feet.

  2. Jupiter is a planet of extremes—it’s the biggest in our solar system, it spins the fastest, it hosts the most moons, and it has the most turbulent atmosphere. But one of its most recognizable features, an enormous storm known as the Great Red Spot, is coming up short. The storm has been getting smaller for decades, but recent images show that it’s now shrinking even faster.

  3. The Chernobyl nuclear disaster had a high ecological cost, with local wildlife suffering from physical deformities and reduced populations. The site has since emerged as a unique environment for scientists to study the long-term effects of continuous radiation exposure on plants and animals. A recent study showed that many bird species are surprisingly adaptable to life in highly radioactive areas.

  4. The unusual severity of 1918’s “Spanish flu” pandemic has eluded explanation for nearly a century. Unlike typical flu epidemics, most of the victims in 1918 were otherwise healthy adults that succumbed to secondary infections. Unexpectedly, children and the elderly frequently recovered. The answer may lie in the 1918 flu's evolutionary relationship to other flu strains that infected different generations in childhood.

  5. Astronomers have detected evidence of the young Universe’s formative growth spurt in the moments following the Big Bang. After more than a decade of observations and data analysis with a South Pole telescope called BICEP2, researchers detected distortions left in ancient light, the first direct evidence of the sudden and dramatic change that launched the Universe as we know it.
