    Top 10 stories of 2018: Climate change, gene-edited babies, hidden craters and more

    In 2018, we saw just how much power science has to make a real impact. 

    Science News’ top stories of the year include a literal impact — the hidden contours of what appears to be a massive crater created when a meteorite slammed into Greenland long ago. That discovery ranks among our Top 10 partly because it’s just cool, but also because it raises the tantalizing prospect of solving a...

    News of the first gene-edited babies ignited a firestorm

    A Chinese scientist surprised the world in late November by claiming he had created the first gene-edited babies, who at the time of the announcement were a few weeks old. Scientists and ethicists quickly responded with outrage.

    In an interview with the Associated Press and in a video posted November 25, Jiankui He announced that twin girls with a gene altered to reduce the risk of...

    To assemble a Top 10 list, Science News starts in June

    When most people were thinking about summer vacation, we were contemplating the biggest science stories of 2018.

    Yep, it takes more than six months of effort to put together Science News’ annual issue on the Top 10 science stories of the year. 2018 was no different, though we were hit with some exciting twists that had us revisiting our decisions just a week or so before closing the...

    Hybrid rice engineered with CRISPR can clone its seeds

    After more than 20 years of theorizing about it, scientists have tweaked a hybrid variety of rice so that some of the plants produce cloned seeds. No plant sex necessary. The feat, described December 12 in Nature, is encouraging for efforts to feed an increasingly crowded world.

    Crossing two good varieties of grain can make one fabulous one, combining the best versions of genes to give...

    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...

    Development near natural areas puts more Californians in the path of wildfires

    In the past week, the Camp Fire has killed at least 56 people and leveled the Northern California town of Paradise. Another wildfire raging through the Los Angeles suburbs, the Woolsey Fire, has already destroyed more than 500 buildings and forced some 250,000 people to evacuate their homes.

    Such disasters are likely to occur more frequently in the coming years, data from recent years...

    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...
