    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...

    Baby macaques are the first primates to be cloned like Dolly the Sheep

    Meet Zhong Zhong and Hua Hua, the first primates cloned by reprogramming adult cells.

    Two decades after Dolly the Sheep was successfully cloned (SN: 3/1/97, p. 132), Chinese researchers have used the same technique — somatic cell nuclear transfer — to clone two healthy baby macaque monkeys. The results, reported January 24 in Cell, could lead to more efficient...

    In a tally of nerve cells in the outer wrinkles of the brain, a dog wins

    If more nerve cells mean more smarts, then dogs beat cats, paws down, a new study on carnivores shows. That harsh reality may shock some friends of felines, but scientists say the real surprises are inside the brains of less popular carnivores. Raccoon brains are packed with nerve cells, for instance, while brown bear brains are sorely lacking.

    By comparing the numbers of nerve cells, or...

    Bones show Dolly’s arthritis was normal for a sheep her age

    In the scientific version of her obituary, Dolly the Sheep was reported to have suffered from severe arthritis in her knees. The finding and Dolly’s early death from an infection led many researchers to think that cloning might cause animals to age prematurely.

    But new X-rays of Dolly’s skeleton and those of other cloned sheep and Dolly’s naturally conceived daughter Bonnie indicate that...

    Face it: Sheep are just like us when it comes to recognizing people

    View the video

    Emma Watson, Jake Gyllenhaal, journalist Fiona Bruce and Barack Obama all walk into a sheep pen. No, this isn’t the beginning of a baaa-d joke.

    By training sheep using pictures of these celebrities, researchers from the University of Cambridge discovered that the animals are able to recognize familiar faces from 2-D images. Given a choice, the sheep picked the...

    Cracking the body clock code wins trio a Nobel Prize

    Discoveries about the molecular ups and downs of fruit flies’ daily lives have won Jeffrey C. Hall, Michael Rosbash and Michael W. Young the Nobel Prize in physiology or medicine.

    These three Americans were honored October 2 by the Nobel Assembly at the Karolinska Institute in Stockholm for their work in discovering important gears in the circadian clocks of animals. The trio will...

    Here’s what the Science News family did for the eclipse

    View the video

    We came. We saw. We earned our 2017 eclipse t-shirts.

    For us, the Aug. 21 total solar eclipse was the culmination of weeks — nay, months — of planning the stories you’ve recently seen on Science News. And as the big day finally approached, many members of the Science News staff past and present traveled far and wide to experience the spectacle.

    Undeterred by...

    Today is the day! A last-minute guide for watching the Great American Eclipse

    Just a stab in the dark, but you’ve probably heard: There is a total solar eclipse today, August 21.

    For the first time since 1979, the moon’s shadow will zip across the continental United States. The shadow will travel from Oregon to South Carolina in a swift 92 minutes. For those in the path of totality, total darkness will last only a couple of minutes. There and elsewhere in most of...

    Gene editing creates virus-free piglets

    Pigs are a step closer to becoming organ donors for people.

    Researchers used molecular scissors known as CRISPR/Cas9 to snip embedded viruses out of pig DNA. Removing the viruses — called porcine endogenous retroviruses, or PERVs — creates piglets that can’t pass the viruses on to transplant recipients, geneticist Luhan Yang and colleagues report online August 10 in Science.
