    Even in the shade, a car’s interior can get lethally hot

    Don’t count on a shady parking spot to save a child left in the back seat on a hot day.

    A new analysis of temperatures inside parked cars reveals that a toddler in a sunbathed vehicle would reach lethal body temperatures faster than one left in the shade. But even in a shaded car, a child could die from overheating within a few hours, researchers report online May 23 in Temperature.

    Fleets of self-driving taxis could be choreographed to cut traffic

    Self-driving taxis that use an algorithm to work together like a well-oiled machine could someday cut down on city traffic.

    Researchers have created a computer program that can continually analyze incoming ride-hailing requests sent from a smartphone app and plot the most efficient course for each car in a self-driving fleet to take (SN Online: 11/21/17). Unlike standard taxis, which...

    Nanoparticles could help rescue malnourished crops

    Synthetic nanoparticles used to fight cancer could also heal sickly plants.

    The particles, called liposomes, are nanosized, spherical pouches that can deliver drugs to specific parts of the body (SN: 12/16/06, p. 398). Now, researchers have filled these tiny care packages with fertilizing nutrients. The new liposomes, described online May 17 in Scientific Reports, soak into plant leaves...

    This self-driving car could one day take you on a real road trip

    A new kind of navigation system could help self-driving cars take the road less traveled.

    Most autonomous vehicles test-driving in cities navigate using 3-D maps marking every curbside and off-ramp with almost centimeter-level precision (SN Online: 11/21/17). But there are millions of miles of open road that tech companies aren’t likely to plot in such detail any time soon.

    Website privacy policies don’t say much about how they share your data

    If you want to know how a website shares your personal data, you might be tempted to slog through its online privacy policy. Be prepared for disappointment. Website privacy policies explicitly disclose only a fraction of sites’ data-sharing practices, according to new research that casts doubt on whether users can make informed decisions about their online activity.

    The research,...

    Private web browsing doesn’t mean no one is watching

    Take a quiz on web privacy

    Private web browsing isn’t nearly as private as many people think.

    Major web browsers, such as Google’s Chrome and Apple’s Safari, offer a private browsing option, sometimes known as “incognito.” The option allows people to surf the internet through a private window that doesn’t log activity into the browser’s history or influence future autofill...

    Why touch can be such a creepy sensation in VR

    There’s a fine line between immersive and unnerving when it comes to touch sensation in virtual reality.

    More realistic tactile feedback in VR can ruin a user’s feeling of immersion, researchers report online April 18 in Science Robotics. The finding suggests that the “uncanny valley” — a term that describes how humanoid robots that look almost but not quite human are creepier than their...

    Here’s why putting a missile defense system in space could be a bad idea

    COLUMBUS, Ohio — A beefed-up missile defense system might seem like a good idea in a time of heightened nuclear tensions. But such enhancements could have dangerous consequences.

    The current U.S. missile defense system isn’t all it was cracked up to be, performing unreliably in tests, physicist and missile defense expert Laura Grego argued April 14 at a meeting of the American Physical...

    The Facebook data debacle may not change internet behavior

    If you’re not paying, you’re the product, so the saying goes. For years, Facebook users have known that they — or, more specifically, their data — make up the bulk of the goods the social media company leverages for profit.

    Then came news that London-based data firm Cambridge Analytica accessed an estimated 87 million Facebook profiles without permission and used that data for political...

    Using laser tweezers, chemists nudged two atoms to bond

    For the first time, researchers have played matchmaker between two specific atoms, joining them together to form a molecule.

    Typically, chemists make molecules by mixing up many constituent atoms, some of which stick to each other to form the desired compounds. In the new, supercontrolled chemical reaction, researchers trapped a single sodium atom in one optical tweezer — a device that...
