    Readers react to the SN 10 and Jocelyn Bell Burnell

    Point, counterpoint

    In “The SN 10: These scientists defy limits to tackle big problems” (SN: 10/13/18, p. 18), Science News profiled 10 early- and mid-career scientists who are pushing boundaries to answer pressing questions facing science and society.

    Some readers had strong reactions to the profiles.

    Charles Eby praised stories about the SN 10 scientists. “Of course I love to...

    Manta rays have an unusual mouth filter that resists clogging

    Manta rays were built for speed — and to filter feed.

    The aerodynamic ocean dwellers efficiently separate plankton from seawater using a previously unknown kind of filtration system that resists clogs and captures tiny bits of plankton, researchers report September 26 in Science Advances.

    Mantas are filter feeders, like many other ocean creatures. They pull plankton-laden seawater...

    Anshumali Shrivastava uses AI to wrangle torrents of data

    Anshumali Shrivastava, 33Computer ScienceRice University

    The world is awash in data, and Anshumali Shrivastava may save us from drowning in it.

    Every day, over 1 billion photos are posted online. In a single second, the Large Hadron Collider can churn out a million gigabytes of observations. Big data is ballooning faster than current computer programs can analyze it.

    “We have...

    Wildfires make their own weather, and that matters for fire management

    Wildfires are not known for their restraint. They’ll jump rivers, spew whirling dervishes of flames and double in size overnight.

    Take the Carr Fire — one of California’s most destructive — sparked in mid-July when the rim of a flat tire met pavement. As the blaze grew, it jumped across the Sacramento River and sparked a flaming whirlwind that trapped and killed a firefighter near...

    A freshwater, saltwater tug-of-war is eating away at the Everglades

    The boardwalk at Pa-hay-okee Overlook is a brief, winding path into a dreamworld in Everglades National Park. Beyond the wooden slats, an expanse of gently waving saw grass stretches to the horizon, where it meets an iron-gray sky. Hardwood tree islands — patches of higher, drier ground called hammocks — rise up from the prairie like surfacing swimmers. The rhythmic singing of cricket frogs is...

    More than 2 billion people lack safe drinking water. That number will only grow.

    Freshwater is crucial for drinking, washing, growing food, producing energy and just about every other aspect of modern life. Yet more than 2 billion of Earth’s 7.6 billion inhabitants lack clean drinking water at home, available on demand.

    A major United Nations report, released in June, shows that the world is not on track to meet a U.N. goal: to bring safe water and sanitation to...

    As waters rise, coastal megacities like Mumbai face catastrophe

    Each year when the monsoon rain sheets down and the tides swell over coastal Mumbai, Saif shutters his soda shop on Juhu Beach and takes shelter up in the rafters. Still, the water invades through the roof and over the concrete floors, sometimes reaching as high as the freezers full of ice cream.

    For 36-year-old Saif, the coastal megacity’s chronic flooding is stressful. “What would...

    People are bad at spotting fake news. Can computer programs do better?

    Scrolling through a news feed often feels like playing Two Truths and a Lie.

    Some falsehoods are easy to spot. Like reports that First Lady Melania Trump wanted an exorcist to cleanse the White House of Obama-era demons, or that an Ohio school principal was arrested for defecating in front of a student assembly. In other cases, fiction blends a little too well with fact. Was CNN really...

    Underwater fiber-optic cables could moonlight as earthquake sensors

    The global network of seafloor cables may be good for more than ferrying digital communication between continents. These fiber-optic cables could also serve as underwater earthquake detectors, researchers report online June 14 in Science.

    “It’s a very exciting proposition,” says Barbara Romanowicz, a seismologist at the University of California, Berkeley and the Collège de France in...

    A new AI can focus on one voice in a crowd

    Much like someone listening to a conversation at a crowded party, a new artificial intelligence can tune out background noise in videos to hear what a particular person on screen is saying.

    Humans are naturally good at focusing on specific voices amidst the din — a phenomenon known as the cocktail party effect (SN Online: 4/29/14). But until now, programs designed to listen for specific...
