    A new map exhibit documents evolving views of Earth’s interior

    Much of what happens on the Earth’s surface is connected to activity far below. “Beneath Our Feet,” a temporary exhibit at the Norman B. Leventhal Map Center in the Boston Public Library, explores the ways people have envisioned, explored and exploited what lies underground.

    “We’re trying to visualize those places that humans don’t naturally go to,” says associate curator Stephanie Cyr...

    Skeletons could provide clues to who wrote or protected the Dead Sea Scrolls

    BOSTON — A decades-long debate over who once occupied a settlement located near the caves where the Dead Sea Scrolls were found has taken a chaste turn.

    Analyses of 33 newly excavated skeletons of people buried at the West Bank site, Qumran, supports a view that the community consisted of a religious sect of celibate men. Anthropologist Yossi Nagar of the Israel Antiquities Authority in...

  • 50 years ago, artificial limbs weren’t nearly as responsive

    Electric limbs

    Very subtle control of artificial limbs by means of a tiny electronic device may become possible.… [The] electronic device … [is] designed to be injected into a muscle through a thick hypodermic needle. A tiny package strapped to the outside of the limb will beam radio waves at the device, which will return them, modified by the electric current produced in the muscle. — ...

    Philosophical critique exposes flaws in medical evidence hierarchies

    Immanuel Kant was famous for writing critiques.

    He earned his status as the premier philosopher of modern times with such works as Critique of Pure Reason, Critique of Practical Reason and Critique of Judgment. It might have been helpful for medical science if he had also written a critique of evidence.

    Scientific research supposedly provides reliable evidence for physicians to...

    Cholera pandemics are fueled by globe-trotting bacterial strains

    Cholera strains behind worldwide outbreaks of the deadly disease over the last five decades are jet-setters rather than homebodies.

    It had been proposed that these cholera epidemics were homegrown, driven by local strains of Vibrio cholerae living in aquatic ecosystems. But DNA fingerprints of the V. cholerae strains behind recent large outbreaks in Africa and Latin America were more...

    Why the wiggle in a crowd’s walk can put a wobble in a bridge

    View the video

    Some bridges could really put a swing in your step.

    Crowds walking on a bridge can cause it to sway — sometimes dangerously. Using improved simulations to represent how people walk, scientists have now devised a better way to calculate under what conditions this swaying may arise, researchers report November 10 online in Science Advances.

    When a bridge —...

    Face it: Sheep are just like us when it comes to recognizing people

    View the video

    Emma Watson, Jake Gyllenhaal, journalist Fiona Bruce and Barack Obama all walk into a sheep pen. No, this isn’t the beginning of a baaa-d joke.

    By training sheep using pictures of these celebrities, researchers from the University of Cambridge discovered that the animals are able to recognize familiar faces from 2-D images. Given a choice, the sheep picked the...

    Alzheimer’s protein can travel from blood to build up in the brain

    An Alzheimer’s-related protein can move from the blood to the brain and accumulate there, experiments on mice show for the first time.

    The results, published online October 31 in Molecular Psychiatry, suggest that the protein amyloid-beta outside the brain may contribute to the Alzheimer’s disease inside it, says Mathias Jucker, a neurobiologist at the University of Tübingen in Germany....

    Invasive species are a growing global threat

    The Aliens Among UsLeslie AnthonyYale Univ. Press, $30

    Remote Bouvet Island, a tiny, glacier-smothered landmass in the South Atlantic rimmed by 500-meter-tall cliffs, has a notable distinction: It’s the only known spot on Earth, scientists say, that has zero invasive species. Every other place, and every person, on the planet is at least indirectly affected by one or more species...

    See a new mosaic of images of comet 67P from the Rosetta mission

    A year after the Rosetta spacecraft’s rendezvous with comet 67P/Churyumov-Gerasimenko came to an end, the views are still stunning. This montage, released in September by the European Space Agency, includes 210 of the thousands of images taken by Rosetta and the Philae lander and recaps the daring mission to explore the space rock. The images are arranged chronologically (starting at the top...
