    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.

    Yang,...

    One in three U.S. adults takes opioids, and many misuse them

    Nearly 5 percent of U.S. adults misused prescription opioids in 2015, a new study shows.

    Based on the National Survey on Drug Use and Health, an in-person survey of more than 50,000 people, researchers estimate that 91.8 million, or 37.8 percent, of adults used prescription opioids in 2015. Some 11.5 million people misused the painkillers, and 1.9 million people reported opioid...

    Giant mud balls roamed the early solar system

    The earliest asteroids were probably made of mud, not rock.

    Radioactive heat in the early solar system could have melted globs of dust and ice before they had a chance to turn to rock, a new simulation published July 14 in Science Advances shows. The results could solve several puzzles about the composition of meteorites found on Earth and may explain why asteroids are different from...

    Bones make hormones that communicate with the brain and other organs

    Long typecast as the strong silent type, bones are speaking up.

    In addition to providing structural support, the skeleton is a versatile conversationalist. Bones make hormones that chat with other organs and tissues, including the brain, kidneys and pancreas, experiments in mice have shown.

    “The bone, which was considered a dead organ, has really become a gland almost,” says Beate...
