    Chinese scientists raise ethical questions with first gene-edited babies

    A Chinese scientist’s surprise announcement on the eve of an international human gene-editing summit that he has already created the world’s first gene-edited babies has led to swift condemnation.

    Jiankui He is expected to discuss his work November 28 in Hong Kong at the second International Summit on Human Genome Editing. But in an interview with the Associated Press, and in a video...

    Why a chemistry teacher started a science board game company

    A physicist, a gamer and two editors walk into a bar. No, this isn’t the setup for some joke. After work one night, a few Science News staffers tried out a new board game, Subatomic. This deck-building game combines chemistry and particle physics for an enjoyable — and educational — time.

    Subatomic is simple to grasp: Players use quark and photon cards to build protons, neutrons and...

    Gene editing creates mice with two biological dads for the first time

    For the first time, researchers have created mice with two dads. No female contributed to the rodents’ genetic makeup.

    This unusual reproduction took place in a lab where researchers gathered fathers’ stem cells, and used them to produce embryos that were implanted into surrogate mothers. The technique required scientists to edit the animals’ genes in order for the mice to mature enough...

    Gene editing can speed up plant domestication

    Gene editing can speed up plant domestication, taming wild vines, bushes and grasses and turning them into new crops.

    Editing just two genes in ground cherries (Physalis pruinosa) produced plants that yielded more and bigger fruit, researchers report October 1 in Nature Plants. Those edits mimic changes that occurred in tomato plants during domestication, bringing the sweet tomato...

    In lab tests, this gene drive wiped out a population of mosquitoes

    A new gene drive may push a species of malaria-carrying mosquito to extinction.

    In a small-scale laboratory study, the genetic engineering tool caused Anopheles gambiae mosquitoes to stop producing offspring in eight to 12 generations, researchers report September 24 in Nature Biotechnology. If the finding holds up in larger studies, the gene drive could be the first capable of wiping...

    Jocelyn Bell Burnell wins big physics prize for 1967 pulsar discovery

    Jocelyn Bell Burnell first noticed the strange, repeating blip in 1967. A University of Cambridge graduate student at the time, she had been reviewing data from a radio telescope she had helped build near campus. Persistent tracking revealed the signal’s source to be something entirely unknown up to that point — a pulsar, or a rapidly spinning stellar corpse that sweeps beams of radio waves...

    CRISPR gene editing relieves muscular dystrophy symptoms in dogs

    Gene editing can reverse muscular dystrophy in dogs.

    Using CRISPR/Cas9 in beagle puppies, scientists have fixed a genetic mutation that causes muscle weakness and degeneration, researchers report online August 30 in Science.

    Corrections to the gene responsible for muscular dystrophy have been made before in mice and human muscle cells in dishes, but never in a larger mammal. The...

    See the ‘periodic table’ of molecular knots

    Like a scouting handbook for the molecular realm, a new chart reveals how to tie molecules up in knots of increasing complexity.

    Mathematicians have cataloged billions of distinct knot types, but researchers have been able to make only a few molecular versions. Scientists craft the minuscule knots using a solution filled with building blocks of curved strings of atoms, which glom onto...
