Science News hasn’t been standing still; people can find our breaking news and in-depth coverage in the flagship magazine as well as on the Science News website, which drew more than...02/22/2018 - 10:46 Science & Society
In a white lab coat and blue latex gloves, Neda Vishlaghi peers through a light microscope at six milky-white blobs. Each is about the size of a couscous grain, bathed in the pale orange broth of a petri dish. With tweezers in one hand and surgical scissors in the other, she deftly snips one tiny clump in half.
When growing human brains, sometimes you need to do some pruning.
Everybody’s a critic. Even back in second century Egypt.
While digging in Tebtunis in northern Egypt in the winter of 1899–1900, British archaeologists stumbled upon portraits of affluent Greco-Egyptians placed over the faces of mummies. One grave contained an ink and chalk sketch, a bit larger than a standard sheet of printer paper, of a woman from around the years A.D. 140 to 160. The...

Lab-grade flight tracking has gone wild, creating a broad new way of studying some of the flashiest of natural acrobats, wild hummingbirds.
One of the findings: Bigger hummingbird species don’t seem handicapped by their size when it comes to agility. A battleship may not be as maneuverable as a kayak, but in a study of 25 species, larger hummingbirds outdid smaller...
Like sailors and spelunkers, physicists know the power of a sturdy knot.
Some physicists have tied their hopes for a new generation of data storage to minuscule knotlike structures called skyrmions, which can form in magnetic materials. Incredibly tiny and tough to undo, magnetic skyrmions could help feed humankind’s hunger for ever-smaller electronics.
On traditional hard drives,...

Some cosmologists hope to explain the universe’s accelerating expansion by fully accounting for the universe’s lumpiness, Emily Conover reported in “Simulating the universe using Einstein’s theory of gravity may solve cosmic puzzles” (SN: 11/25/17, p. 22).
The universe’s accelerating expansion “is apparently based on the observation of objects that are...
People tend to think of memories as deeply personal, ephemeral possessions — snippets of emotions, words, colors and smells stitched into our unique neural tapestries as life goes on. But a strange series of experiments conducted decades ago offered a different, more tangible perspective. The mind-bending results have gained unexpected support from recent studies.
In 1959, James Vernon...
Consider everything your smartphone has done for you today. Counted your steps? Deposited a check? Transcribed notes? Navigated you somewhere new?
Smartphones make for such versatile pocket assistants because they’re equipped with a suite of sensors, including some we may never think — or even know — about, sensing, for example, light, humidity, pressure and temperature.
T he Okarian rover was in trouble. The yellow Humvee was making slow progress across a frigid, otherworldly landscape when planetary scientist Pascal Lee felt the rover tilt backward. Out the windshield, Lee, director of NASA’s Haughton Mars Project, saw only sky. The rear treads had broken through a crack in the sea ice and were sinking into the cold water.
True, there are signs of...
