    Modern tech unravels mysteries of Egyptian mummy portraits

    Everybody’s a critic. Even back in second century Egypt.

    While digging in Tebtunis in northern Egypt in the winter of 1899–1900, British archaeologists stumbled upon portraits of affluent Greco-Egyptians placed over the faces of mummies. One grave contained an ink and chalk sketch, a bit larger than a standard sheet of printer paper, of a woman from around the years A.D. 140 to 160. The...

    Mix of metals in this Picasso sculpture provides clues to its mysterious origins

    AUSTIN, Texas — An analysis of the metals in dozens of Picasso’s bronze sculptures has traced the birthplace of a handful of the works of art to the outskirts of German-occupied Paris during World War II.

    This is the first time that the raw materials of Picasso’s sculptures have been scrutinized in detail, conservation scientist Francesca Casadio of the Art Institute of Chicago said...

    Americans would welcome alien life rather than fear it

    AUSTIN, Texas — If alien microbes crash-land on Earth, they may get a warm welcome.

    When people were asked how they would react to the discovery of extraterrestrial microbial life, they give generally positive responses, researchers reported at a news conference February 16 at the annual meeting of the American Association for the Advancement of Science.

    This suggests that if...

    Genes could record forensic clues to time of death

    Dying, it turns out, is not like flipping a switch. Genes keep working for a while after a person dies, and scientists have used that activity in the lab to pinpoint time of death to within about nine minutes.

    During the first 24 hours after death, genetic changes kick in across various human tissues, creating patterns of activity that can be used to roughly predict when someone died,...

    4 questions about the new U.S. budget deal and science

    Editor’s Note: This story was updated February 9 to note President Trump’s fiscal year 2019 budget proposal.

    A two-year spending package, passed by Congress in the wee hours of February 9 and signed into law by President Trump hours later, could add to the coffers of U.S. science agencies.

    The bipartisan deal raises the caps on defense and nondefense discretionary spending by...

  • 50 years on, nuclear fusion still hasn’t delivered clean energy

    Power within 30 years

    Controlled thermonuclear fusion is moving so well that full-scale development could begin within five years, says Dr. David J. Rose....It might take 20 to 30 years beyond that before fusion could move into the power grid, though, he predicts. — Science News, February 17, 1968

    In play, kids and scientists take big mental leaps

    I know a lot of adults who don’t like to cook, but I’ve never met a child who doesn’t enjoy playing with a toy kitchen — or one who doesn’t want to help chop vegetables for dinner. Other versions of practical play: A cousin, at the age of just 4 or 5, asked for only one thing for Christmas — a snow brush. And on a beach trip last year, I witnessed a duo of 2-year-olds squealing with...

    Readers ask about supernovas, dark energy and more

    Dying light

    Supernova iPTF14hls has erupted continually since its discovery in 2014, fluctuating in brightness at least five times. It may have had two other outbursts in the past, Lisa Grossman reported in “This star cheated death, exploding again and again” (SN: 12/9/17, p. 8).

    Reddit user Bobgushmore wondered if the exploding star might actually be a supernova impostor similar to...

    ‘Death: A Graveside Companion’ offers an outlet for your morbid curiosity

    Death: A Graveside CompanionJoanna Ebenstein (ed.)Thames & Hudson, $40

    Death: A Graveside Companion makes for an unusual coffee-table book, with its coppery etched Grim Reaper on the cover. Yet you may be surprised by how much fun it is to pore through the book’s lavish artwork of skulls, cadavers and fanciful imaginings of the afterlife.

    There is, after all, a reason for...
