    On social media, privacy is no longer a personal choice

    Some people might think that online privacy is a, well, private matter. If you don’t want your information getting out online, don’t put it on social media. Simple, right?

    But keeping your information private isn’t just about your own choices. It’s about your friends’ choices, too. Results from a study of a now-defunct social media site show that the inhabitants of the digital age may...

    Why is this year’s solar eclipse such a big deal for scientists?

    The sky will go dark. The temperature will drop. Stars will shine in the middle of the day. For the first time in nearly a century, millions of Americans from coast-to-coast will witness a total solar eclipse. Those who have watched the sun suddenly snuff out say it’s an otherworldly feeling. It can be humbling. It can be spiritual. It can change the course of history (SN: 5/13/17, p. 29)....

    Can DNA predict a face?

    Florida police are searching for a man who lurks in the shadows.

    For more than two years, he has terrorized at least a dozen women, peeping into windows and slipping into bedrooms to watch them sleep. He has touched several women’s feet or hair — some, he has sexually assaulted.

    The media dubbed him the “Serial Creeper,” and police are desperate to find him. In September, they...

    The human genome takes shape and shifts over time

    If you could unravel all the DNA in a single human cell and stretch it out, you’d have a molecular ribbon about 2 meters long and 2 nanometers across. Now imagine packing it all back into the cell’s nucleus, a container only 5 to 10 micrometers wide. That would be like taking a telephone cord that runs from Manhattan to San Francisco and cramming it into a two-story suburban house.

    How to reconstruct the face of an extinct human ancestor

    View the slideshow

    Cícero Moraes is adding new portraits to the human family album. The 3-D designer based in Sinop, Brazil, has digitally reconstructed the faces of over 15 extinct hominid species, including Paranthropus boisei, a distant cousin to modern humans. The faces are on display at the University of Padua in Italy (see "The expressive face of human history on display.")

    Little thylacine had a big bite

    In the northeast corner of Queensland lies one of Australia’s great treasures — the Riversleigh World Heritage Area, home to more than 250 sites that are rich in fossils. In that region, some 24 to 11.6 million years ago, as many as five relatives of the extinct Tasmanian tiger, or thylacine, roamed forests along with giant carnivorous rat-kangaroos, marsupial lions, the world’s oldest known...

    Little Red Riding Hood gets an evolutionary makeover

    Back off, Big Bad Wolf. The Ravenous Data Cruncher has cornered “Little Red Riding Hood,” brandishing a statistical exposé of the fictional girl’s hazy past.

    In computer analyses that track the evolution of 58 documented folktales, anthropologist Jamshid Tehrani of Durham University in England finds that related versions of “Little Red Riding Hood” spread from a European origin over at...

    Facebook doesn’t feel right

    A big chunk of social media users say that digital communications don’t hold an old fashioned candle to face-to-face conversations. Among 300 tech-savvy college students, roughly half feel uncomfortable interacting on Facebook, Twitter and other social media but do so because it’s unavoidable, Zeynep Tufekci of the University of North Carolina at Chapel Hill...

    DNA stores poems, a photo and a speech

    Big data could soon be stored in a very small package: DNA. A team of scientists has demonstrated that storing information in synthetic DNA could represent a feasible approach to managing data in the long term, bumping aside the magnetic tape favored by archivists today.

    The approach, published online January 23 in Nature, relies on technologies that are likely to become faster and...

    Nouveaux Antennas

    Television viewers may be tossing out their old rabbit ears in favor of sleeker digital receivers, but scientists are raising the microscopic equivalents of antennas to new prominence.

    Most cells in the body, from light-gathering eye cells to kidney cells to brain cells, sport a single, prominent hairlike structure sticking out like an index finger flashing...
