    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...

    Babies can recover language skills after a left-side stroke

    AUSTIN, Texas — Babies’ stroke-damaged brains can pull a mirror trick to recover.

    A stroke on the left side of the brain often damages important language-processing areas. But people who have this stroke just before or after birth recover their language abilities in the mirror image spot on the right side, a study of teens and young adults shows. Those patients all had normal language...

    This stick-on patch could keep tabs on stroke patients at home

    AUSTIN, Texas — Stretchy sensors that stick to the throat could track the long-term recovery of stroke survivors.

    These new Band-Aid‒shaped devices contain motion sensors that detect muscle movement and vocal cord vibrations. That sensor data could help doctors diagnose and monitor the effectiveness of certain treatments for post-stroke conditions like difficulty swallowing or talking,...

    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...

    Ants practice combat triage and nurse their injured

    No wounded left behind — not quite. Ants that have evolved battlefield medevac carry only the moderately wounded home to the nest. There, those lucky injured fighters get fast and effective wound care.

    Insect colonies seething with workers may seem unlikely to stage elaborate rescues of individual fighters. Yet for Matabele ants (Megaponera analis) in sub-Saharan Africa — with a mere 1,...

    James Webb Space Telescope challenges artists to see in infrared

    With an astronomer’s toolkit and an artist’s eye, Zoltan Levay has transformed raw data from the Hubble Space Telescope into stunning space vistas for almost a quarter century (SN: 4/18/15, p. 4). He’s now preparing for a new challenge: Working with light not visible to human eyes.

    Levay’s next charge is the James Webb Space Telescope, set to launch in 2019. Unlike Hubble, which mostly...

    To hear the beat, your brain may think about moving to it

    If you’ve ever felt the urge to tap along to music, this research may strike a chord.

    Recognizing rhythms doesn’t involve just parts of the brain that process sound — it also relies on a brain region involved with movement, researchers report online January 18 in the Journal of Cognitive Neuroscience. When an area of the brain that plans movement was disabled...

    Strong winds send migrating seal pups on lengthier trips

    PORTLAND, Ore. — Native American fishermen in Alaska have long said that seal pups go with the wind rather than struggle against it. Now, a new study confirms that wisdom. Migrating northern fur seal pups travel hundreds of kilometers farther in blustery years than in milder years, researchers reported February 14 at the American Geophysical Union’s Ocean Sciences meeting. Those epic journeys...

    Household products make surprisingly large contributions to air pollution

    AUSTIN, Texas — To reduce your impact on air quality, you might expect to trade in your gas-guzzling clunker of a car — but you can also unplug those air fresheners. 

    In urban areas, emissions from consumer goods such as paint, cleaning supplies and personal care products now contribute as much to ozone and fine particulate matter in the atmosphere as do emissions from...
