    Chaco Canyon’s ancient civilization continues to puzzle

    Chaco Canyon is a land of extremes. Summer heat scorches the desert canyon, which is sandwiched between sandstone cliffs nearly two kilometers above sea level in New Mexico’s northwestern corner. Bitter cold sweeps in for winter. Temperatures can swing as many as 28 degrees Celsius during the course of a day. Through it all, Chaco Canyon maintains a desolate beauty and a craggy pride as home...

    Jumping genes play a big role in what makes us human

    Face-to-face, a human and a chimpanzee are easy to tell apart. The two species share a common primate ancestor, but over millions of years, their characteristics have morphed into easily distinguishable features. Chimps developed prominent brow ridges, flat noses, low-crowned heads and protruding muzzles. Human noses jut from relatively flat faces under high-domed crowns.

    Those facial...

    Naked singularity might evade cosmic censor

    Certain stealthy spacetime curiosities might be less hidden than thought, potentially exposing themselves to observers in some curved universes.

    These oddities, known as singularities, are points in space where the standard laws of physics break down. Found at the centers of black holes, singularities are generally expected to be hidden from view, shielding the universe from their...

    The first Cassini to explore Saturn was a person

    As the Cassini spacecraft plunges toward its death on Saturn, the world’s knowledge of the famous ringed planet continues to accumulate. Thanks to years of observations by the versatile probe, astronomers now know Saturn as intimately as macaroni knows cheese. But still hardly anyone outside the world of astronomy knows anything about Cassini — and I don’t mean the spacecraft, but the guy it...

    Selfish genes hide for decades in plain sight of worm geneticists

    View the video

    A strain of wild Hawaiian worms has helped unmask long-studied genes as just plain selfish. The scammers beat the usual odds of inheritance and spread extra fast by making mother worms poison some of their offspring.

    Biologists have for decades discussed how two genes in the familiar lab nematode Caenorhabditis elegans might help embryos build their organs. Working...

    Readers concerned about cancer’s sugary disguise

    Sugarcoated

    A new wave of potential immune therapies aims to target the network of complex sugars that coat cancer cells, Esther Landhuis reported in “Cancer’s sweet cloak” (SN: 4/1/17, p. 24). Some of these sugars, called sialic acids, help tumors hide from the immune system.

    “Are the offending sugars referred to in this article the ones we are eating or are they the result of...

    Collider data hint at unexpected new subatomic particles

    A handful of measurements of decaying particles has seemed slightly off-kilter for years, intriguing physicists. Now a new decay measurement at the Large Hadron Collider in Geneva has amplified that interest into tentative enthusiasm, with theoretical physicists proposing that weird new particles could explain the results. Scientists with the LHCb experiment reported the new result on April 18...

    How the house mouse tamed itself

    Got a mouse in the house? Blame yourself. Not your housekeeping, but your species. Humans never intended to live a mouse-friendly life. But as we moved into a settled life, some animals — including a few unassuming mice — settled in, too. In the process, their species prospered — and took over the world.

    The rise and fall of the house mouse’s fortunes followed the stability and...

    There’s still a lot we don’t know about the proton

    Nuclear physicist Evangeline Downie hadn’t planned to study one of the thorniest puzzles of the proton.

    But when opportunity knocked, Downie couldn’t say no. “It’s the proton,” she exclaims. The mysteries that still swirl around this jewel of the subatomic realm were too tantalizing to resist. The plentiful particles make up much of the visible matter in the universe. “We’re made of them...

    Scientists seek early signs of autism

    Soon after systems biologist Juergen Hahn published a paper describing a way to predict whether a child has autism from a blood sample, the notes from parents began arriving. “I have a bunch of parents writing me now who want to test their kids,” says Hahn, of Rensselaer Polytechnic Institute in Troy, N.Y. “I can’t do that.”

    That’s because despite their promise, his group’s results,...
