    Female guppies with bigger brains pick more attractive guys

    When choosing more attractive guys, girl guppies with larger brains have an advantage over their smaller-brained counterparts. But there’s a cost to such brainpower, and that might help explain one of the persistent mysteries of sex appeal, researchers report March 22 in Science Advances.

    One sex often shows a strong preference for some trait in the other, whether it’s a longer fish fin...

    Anatomy analysis suggests new dinosaur family tree

    The standard dinosaur family tree may soon be just a relic.

    After examining more than 400 anatomical traits, scientists have proposed a radical reshuffling of the major dinosaur groups. The rewrite, reported in the March 23 Nature, upsets century-old ideas about dinosaur evolution. It lends support to the accepted idea that the earliest dinosaurs were smallish, two-legged creatures. But...

    Touches early in life may make a big impact on newborn babies’ brains

    Many babies born early spend extra time in the hospital, receiving the care of dedicated teams of doctors and nurses. For these babies, the hospital is their first home. And early experiences there, from lights to sounds to touches, may influence how babies develop.

    Touches early in life in the NICU, both pleasant and not, may shape how a baby’s brain responds to gentle touches later, a...

    Lab tests aren’t the answer for every science question

    In the second half of the 17th century, the chemist and polymath Robert Boyle and philosopher Thomas Hobbes engaged in a divisive debate centered on a temperamental, mechanical contraption known as an air pump. In a series of famous experiments, Boyle used the air pump, which has been called “the cyclotron of its age,” to test basic scientific principles such as the relationship between a gas’...

    Readers question supernova physics

    Supernova surprise

    Astronomers continue to learn a lot from supernova 1987A, which burst onto the scene 30 years ago. Thanks to new detectors that can pick up neutrino signals and even gravitational waves, scientists will be ready when the next nearby star explodes, Emily Conover reported in “Waiting for a supernova” (SN: 2/18/17, p. 24).

    Steve Capps wondered how neutrinos inside an...

    How Pluto’s haze could explain its red spots

    Pluto may get its smattering of red spots from the fallout of its hazy blue skies, researchers say.

    Haze particles from the dwarf planet’s atmosphere settle onto all of Pluto’s surfaces. But some regions may become redder and darker than others because parts of the atmosphere collapse, exposing those spots to more surface-darkening radiation from space, researchers report March 22 at the...

    Colorful pinwheel puts a new spin on mouse pregnancy

    View slideshow of other winners

    This rainbow pinwheel of mouse placentas isn’t just an eye-catching, award-winning image. The differences in color also provide researchers with new clues to how a mother’s immune system may affect her or her baby’s health during pregnancy. The work could lead to earlier diagnosis and treatment of preeclampsia, a common pregnancy complication.

    Tool use in sea otters doesn't run in the family

    Aside from being adorable, sea otters and Indo-Pacific bottlenose dolphins share an ecological feat: Both species use tools. Otters crack open snails with rocks, and dolphins carry cone-shaped sponges to protect their snouts while scavenging for rock dwelling fish.

    Researchers have linked tool use in dolphins to a set of differences in mitochondrial DNA — which passes from mother to...

    Large Hadron Collider experiment nabs five new particles

    Physicists have snagged a bounty of five new particles in one go.

    Members of the LHCb experiment, located at the Large Hadron Collider near Geneva, reported the prolific particle procurement in a paper posted online March 14 at arXiv.org. The five particles are each composed of three quarks — a class of particle that makes up larger particles such as protons and neutrons. Each of the new...
