    CRISPR/Cas9 can reverse multiple diseases in mice

    A new twist on gene editing makes the CRISPR/Cas9 molecular scissors act as a highlighter for the genetic instruction book. Such highlighting helps turn on specific genes.

    Using the new tool, researchers treated mouse versions of type 1 diabetes, kidney injury and Duchenne muscular dystrophy, the team reports December 7 in Cell. The new method may make some types of gene therapy easier...

    Bats in China carry all the ingredients to make a new SARS virus

    Viruses in bats may have mixed and matched genes to create the virus that gave rise to the deadly SARS outbreak in 2003, a new study suggests. And it could happen again. All of the ingredients needed to create a new SARS virus are found among viruses currently infecting horseshoe bats, researchers report November 30 in PLOS Pathogens.

    The viruses “are poised to cause future outbreaks,”...

    Parents may one day be morally obligated to edit their baby’s genes

    A doctor explains to a young couple that he has screened the pair’s in vitro fertilized embryos and selected those that had no major inheritable diseases. The couple had specified they want a son with hazel eyes, dark hair and fair skin. Then the doctor announces that he has also taken the liberty of eliminating the “burden” of genetic propensities for baldness, nearsightedness, alcoholism,...

    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...

    Current CRISPR gene drives are too strong for outdoor use, studies warn

    Gene-editing tools heralded as hope for fighting invader rats, malarial mosquitoes and other scourges may be too powerful to use in their current form, two new papers warn.

    Standard forms of CRISPR gene drives, as the tools are called, can make tweaked DNA race through a population so easily that a small number of stray animals or plants could spread it to new territory, predicts a...

    How Asian nomadic herders built new Bronze Age cultures

    Nomadic herders living on western Asia’s hilly grasslands made a couple of big moves east and west around 5,000 years ago. These were not typical, back-and-forth treks from one seasonal grazing spot to another. These people blazed new trails.

    A technological revolution had transformed travel for ancient herders around that time. Of course they couldn’t make online hotel reservations....

    Ancient European farmers and foragers hooked up big time

    Thousands of years ago, hunter-gatherers native to Europe and incoming farmers from what’s now Turkey got up close and personal for a surprisingly long time, researchers say. This mixing reshaped the continent’s genetic profile differently from one region to another.

    Ancient DNA from foragers and farmers in eastern, central and western Europe indicates that they increasingly mated with...

    Scientists replaced 80 percent of a ‘butterfly’ boy’s skin

    In a last-ditch effort to save a dying 7-year-old boy, scientists have used stem cells and gene therapy to replace about 80 percent of his skin.

    This procedure’s success demonstrates that the combination therapy may be effective against some rare genetic skin disorders. The study also sheds light on how the skin replenishes itself, researchers report November 8 in Nature.

    In 2015,...

    Here’s why some water striders have fans on their legs

    For an animal already amazing enough to walk on water, what could growing feather fans on its legs possibly add?

    These fans have preoccupied Abderrahman Khila of the University of Lyon in France, who keeps some 30 species of bugs called water striders walking the tanks in his lab without getting their long, elegant legs wet.

    “Walk” may be too humdrum a word. The 2,200 or so known...

    No more than 800 orangutans from this newly identified species remain

    Orangutans living in forested foothills on the Indonesian island of Sumatra represent a previously unknown species, researchers say.

    Skeletal and genetic evidence puts these apes on a separate evolutionary trajectory from other orangutans in Sumatra (Pongo abelii) and Bornean orangutans (Pongo pygmaeus), says a team led by evolutionary anthropologist Michael Krützen of the University of...
