    Animal study reveals how a fever early in pregnancy can cause birth defects

    Certain birth defects of the face and heart can occur when babies’ mothers have a fever during the first trimester of pregnancy, a crucial time in an embryo’s development. Now scientists have figured out the molecular players that make it so.  

    In an experiment with chicken embryos, a temporary rise in incubation temperature — meant to mimic feverlike conditions — was enough to produce...

    The newest AlphaGo mastered the game with no human input

    AlphaGo just leveled up.

    The latest version of the computer program, dubbed AlphaGo Zero, is the first to master Go, a notoriously complex Chinese board game, without human guidance. Its predecessor — dubbed AlphaGo Lee when it became the first computer program with artificial intelligence, or AI, to defeat a human world champion Go player (SN Online: 3/15/16) — had to study millions of...

    Conspiring with engineers helps make science great

    From what I can tell, there’s a fair amount of friendly rivalry between folks who call themselves “scientists” and those who call themselves “engineers.” Bill Nye, educated as a mechanical engineer, had to defend himself as the “Science Guy” on The Late Show with Stephen Colbert earlier this year: “It’s physics, for four years, it’s physics,” he said. Dean of the Boston University College of...

    Brain boost

    It’s possible that therapies such as external brain stimulation and neurofeedback, as well as some drugs, may one day boost brain flexibility. A new line of research suggests flexibility is important for learning, Laura Sanders reported in “Learning takes brain acrobatics” (SN: 9/16/17, p. 22).

    Online reader Glenn wondered if drugs for Parkinson’s disease and Huntington’s...

    Being a vampire can be brutal. Here’s how bloodsuckers get by.

    Jennifer Zaspel can’t explain why she stuck her thumb in the vial with the moth. Just an after-dark, out-in-the-woods zing of curiosity.

    She was catching moths on a July night in the Russian Far East and had just eased a Calyptra, with brownish forewings like a dried leaf, into a plastic collecting vial. Of the 17 or so largely tropical Calyptra species, eight were known vampires. Males...

    Moms tweak the timbre of their voice when talking to their babies

    Voices carry so much information. Joy and anger, desires, comfort, vocabulary lessons. As babies learn about their world, the voice of their mother is a particularly powerful tool. One way mothers wield that tool is by speaking in the often ridiculous, occasionally condescending baby talk.

    Also called “motherese,” this is a high-pitched, exaggerated language full of short, slow phrases...

    Here’s what space toilets can teach us about finding signs of alien life

    The search for life may get an assist from the call of nature. Astronomers can learn how to study the plumes of subsurface ocean water spewing from icy moons like Saturn’s Enceladus from an unlikely source: Space toilets.

    Future spacecraft might scoop up samples of Enceladus’ plumes. Figuring out what to expect is tricky: It’s hard to replicate the plumes in Earth-based labs. But...

    How volcanoes may have ended the dynasty of Ptolemy and Cleopatra

    A series of volcanic eruptions may have helped bring about the downfall of the last Egyptian dynasty 2,000 years ago.

    By suppressing the monsoons that swelled the Nile River each summer, triggering flooding that supported the region’s agriculture, the eruptions probably helped usher in an era of periodic revolts, researchers report online October 17 in Nature Communications. That...

    This stretchy implant could help kids avoid repeated open-heart surgeries

    A new stretchy prosthetic could reduce the number of surgeries that children with leaking heart valves must undergo.

    The device, a horseshoe-shaped implant that wraps around the base of a heart valve to keep it from leaking, is described online October 10 in Nature Biomedical Engineering. In adults, a rigid ring is used, but it can’t be implanted in children because it would constrict...
