    Bacteria genes offer new strategy for sterilizing mosquitoes

    A pair of bacterial genes may enable genetic engineering strategies for curbing populations of virus-transmitting mosquitoes.

    Bacteria that make the insects effectively sterile have been used to reduce mosquito populations. Now, two research teams have identified genes in those bacteria that may be responsible for the sterility, the groups report online February 27 in Nature and Nature...

    Black hole enjoys fantastically long stellar feast

    Black holes are speed eaters, usually scarfing down a star in less than a year. But a supermassive black hole in a galaxy about 1.8 billion light-years away has been gorging on a single star for more than 10 years – longer than any other observed supermassive black hole meal.

    Astronomers detected the extraordinary feast in X-ray images from ESA’s XMM-Newton spacecraft and NASA’s...

    Most fish turned into fishmeal are species that we could be eating

    A person growing up in Peru in the 1970s or 1980s probably didn’t eat anchoveta, the local species of anchovies. The stinky, oily fish was a food fit only for animals or the very poor. The anchoveta fishery may have been (and still is, in many years) the world’s largest, but it wasn’t one that put food on the table.

    For thousands of years, though, anchoveta fed the people of Peru. It was...

    Newly identified continent Zealandia faces a battle for recognition

    Lurking beneath New Zealand is a long-hidden continent called Zealandia, geologists say. But since nobody is in charge of officially designating a new continent, individual scientists will ultimately have to judge for themselves.

    A team of geologists pitches the scientific case for the new continent in the March/April issue of GSA Today, arguing that Zealandia is a continuous expanse of...

    Bacteria’s amyloids display surprising structure

    Clusters of a toxic bacterial protein have a surprising structure, differing from similar clumps associated with Alzheimer’s and Parkinson’s in humans, scientists report in the Feb. 24 Science.

    These clusters, called amyloids, are defined in part by their structure: straight regions of protein chains called beta strands, folded accordion-style into flat beta sheets, which then stack up...

    A preschooler’s bubbly personality may rub off on friends

    A preschool classroom is an ecosystem unlike any other. Scents of glue and snack time waft through the air. Bright, clunky art papers the walls. Fun-sized furniture makes visiting adults feel like awkward giants. In the name of science, a team of psychologists spent an entire year inside two such rooms, meticulously documenting changes in preschoolers’ personalities.

    By the end of the...

    Physics greats of the 20th century mixed science and public service

    The 20th century will go down in history — it pretty much already has — as the century of the physicist. Physicists’ revolutionizing of the scientific world view with relativity and quantum mechanics might have been enough to warrant that conclusion. Future historians may emphasize even more, though, the role of physicists in war and government. Two such physicists, one born at the century’s...

    Seven Earth-sized planets orbit nearby supercool star

    A nearby ultracool star harbors seven Earth-sized planets, three with orbits that potentially put them in a habitable zone. That makes the system, around a star called TRAPPIST-1, a prime target in the search for signs of alien life. Its discovery also hints that many more cousins of Earth may be out there than astronomers thought.

    “It’s rather stunning that the system has so many Earth-...

    Too many stinkbugs spoil the wine

    How many stressed-out stinkbugs does it take to spoil a batch of wine? More than three per grape cluster, new research says. 

    Stinkbugs are a pest among vintners because of the bugs’ taste for wine grapes and namesake foul smell. When accidentally harvested with the grapes and fermented during the wine-making process, the live insects can release their stink and ruin the wine (SN: 5/5/07...

    Low-status chimps revealed as trendsetters

    Chimps with little social status influence their comrades’ behavior to a surprising extent, a new study suggests.

    In groups of captive chimps, a method for snagging food from a box spread among many individuals who saw a low-ranking female peer demonstrate the technique, say primatologist Stuart Watson of the University of St. Andrews in Fife, Scotland, and colleagues. But in other...
