    Microbes survived inside giant cave crystals for up to 50,000 years

    BOSTON — Microbes found stowed inside giant crystals in caves in Chihuahua, Mexico, may have survived there for tens of thousands of years. The microorganisms, which appear to be vastly different from nearly all life-forms found on Earth, offer a good indication of how resilient life can be in extremely harsh environments, including those found on other planets.

    “These organisms are so...

    Europa lander mission takes another step toward reality

    BOSTON — For the first time since the Viking missions to Mars in the 1970s, NASA is making the search for evidence of life on another world the primary science goal of a space mission. The target world is Jupiter’s moon Europa, considered possibly habitable because of its subsurface ocean.

    The proposed mission, which could be operational in the next two decades, calls for a lander with...

    Common fungus may raise asthma risk

    BOSTON — A fungus among us may tip the body toward developing asthma.

    There’s mounting evidence that early exposure to microbes can protect against allergies and asthma (SN Online: 7/20/16). But “lo and behold, some fungi seem to put kids at risk for asthma,” microbiologist Brett Finlay said February 17 at a news conference during the annual meeting of the American Association for the...

    Juno spacecraft won’t go into shorter orbit around Jupiter

    NASA’s Juno spacecraft will stay in its current 53-day orbit around Jupiter instead of closing into a 14-day orbit as originally planned, the Juno team announced February 17.

    An issue with two helium check valves, which are tied to the spacecraft’s main engine, had scientists concerned. The valves took several minutes to open when the team pressurized the spacecraft’s propulsion system...

    Antarctic sea ice shrinks to record low

    Sea ice around Antarctica shrunk to its lowest monthly extent on record in January, the National Oceanic and Atmospheric Administration reports.

    Antarctic sea ice extent averaged just 4.04 million square kilometers, 1.19 million square kilometers below the 1981 through 2010 average. That’s 280,000 square kilometers smaller than the previous record low, set in 2006.

    The new record...

    Helium’s inertness defied by high-pressure compound

    Helium — the recluse of the periodic table — is reluctant to react with other elements. But squeeze the element hard enough, and it will form a chemical compound with sodium, scientists report.

    Helium, a noble gas, is one of the periodic table’s least reactive elements. Originally, the noble gases were believed incapable of forming any chemical compounds at all. But after scientists...

    Citizen scientists are providing stunning new views of Jupiter

    Stormy, with a good chance of cyclones. That’s the forecast for Jupiter’s south pole — a region never seen before but quickly coming into focus with the help of citizen scientists.

    Music producer Roman Tkachenko’s edited image of Jupiter’s nether regions (featured above) is a perfect example. His enhancements make the swirling cyclones and white oval storms really pop compared with the...

    Ceres harbors homegrown organic compounds

    Dwarf planet Ceres contains the necessary ingredients for life, new data suggest.

    NASA’s Dawn spacecraft has detected organic compounds on Ceres — the first concrete proof of organics on an object in the asteroid belt between Mars and Jupiter. This material probably originated on the dwarf planet itself, the researchers report in the Feb. 17 Science. The discovery of organic compounds,...

    Seagrasses boost ecosystem health by fighting bad bacteria

    BOSTON — For a lawn that helps the environment — and doesn’t need to be mowed — look to the ocean. Meadows of underwater seagrass plants might lower levels of harmful bacteria in nearby ocean waters, researchers reported February 16 during a news conference at the annual meeting of the American Association for the Advancement of Science. That could make the whole ecosystem — from corals to...

    Speech recognition has come a long way in 50 years

    Computers that hear

    Computer engineers have dreamed of a machine that would translate speech into something that a vacuum tube or transistor could understand. Now at last, some promising hardware is being developed.... It is still a long way from the kind of science fiction computer that can understand sentences or long speeches. — Science News, March 4, 1967
