    A new way to turn saltwater fresh can kill germs and avoid gunk buildup

    A new design for sun-powered desalination technology may lead to longer-lasting devices that produce cleaner water.

    The trick boils down to preventing a device’s components from touching the saltwater. Instead, a lid of light-absorbing material rests above a partially filled basin of water, absorbing sunlight and radiating that energy to the liquid below. That evaporates the water to...

    The list of extreme weather caused by human-driven climate change grows

    WASHINGTON – A months-long heat wave that scorched the Tasman Sea beginning in November of 2017 is the latest example of an extreme event that would not have happened without human-caused climate change.

    Climate change also increased the likelihood of 15 other extreme weather events in 2017, from droughts in East Africa and the U.S. northern Plains states to floods in Bangladesh, China...

    Getting goose bumps could boost hair growth

    SAN DIEGO — Getting goose bumps doesn’t just make hairs stand on end; it may also help hair grow.

    Nerves and muscles that raise goose bumps also stimulate stem cells in the skin to make hair follicles and grow hair. Ya-Chieh Hsu, a stem cell researcher at Harvard University, reported the unpublished findings December 9 at the joint meeting of the American Society for Cell Biology and the...

    NASA’s OSIRIS-REx finds signs of water on the asteroid Bennu

    As the asteroid Bennu comes into sharper focus, planetary scientists are seeing signs of water locked up in the asteroid’s rocks, NASA team members announced December 10.

    “It’s one of the things we were hoping to find,” team member Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Md., said in a news conference at the American Geophysical Union meeting in Washington, D.C. “...

    Voyager 2 spacecraft enters interstellar space

    Voyager 2 has entered interstellar space. The spacecraft slipped out of the huge bubble of particles that encircles the solar system on November 5, becoming the second ever human-made craft to cross the heliosphere, or the boundary between the sun and the stars.

    Coming in second place is no mean achievement. Voyager 1 became the first spacecraft to exit the solar system in 2012. But that...

    A satellite screw-up reaffirms Einstein’s theory of gravity

    An orbital oopsie has led to new proof of Albert Einstein’s physics prowess.

    In 2014, two satellites intended for Europe’s Galileo network, the equivalent of the United States’ GPS network, were placed into orbit incorrectly, causing them to travel around Earth in ellipses rather than circles. That wasn’t ideal for the satellites’ originally intended navigational use, but scientists...

    Magnets make a new soft metamaterial stiffen up in a flash

    Magnetism transforms a weird new material from soft to rigid in a split second.

    This metamaterial — a synthetic structure designed to behave in ways that natural materials don’t — comprises a gridlike network of plastic tubes filled with fluid that becomes more viscous in a magnetic field, causing the tubes to firm up. The material could help make more adaptable robots or body armor,...

    A gut-brain link for Parkinson’s gets a closer look

    Martha Carlin married the love of her life in 1995. She and John Carlin had dated briefly in college in Kentucky, then lost touch until a chance meeting years later at a Dallas pub. They wed soon after and had two children. John worked as an entrepreneur and stay-at-home dad. In his free time, he ran marathons.

    Almost eight years into their marriage, the pinky finger on John’s right hand...
