Scientists’ collection of gravitational waves just got a lot bigger

Astronomers have now tallied up more gravitational wave sightings than they can count on their fingers. Scientists with the LIGO and Virgo gravitational wave observatories report four new sets of these ripples in spacetime. Those additions bring the total count to 11, the researchers say in a study published December 3 at, marking major ... Read more

In a first, a woman with a uterus transplanted from a deceased donor gives birth

For the first time, a woman has given birth after receiving a uterus from a deceased donor. A reported 11 women have had babies after uterus transplants from living donors. But this breakthrough, described online December 4 in the Lancet, could boost the availability of viable organs for women who want to become pregnant but ... Read more

Artificial intelligence is mastering a wider variety of jobs than ever before

In 2018, artificial intelligence took on new tasks, with these smarty-pants algorithms acing everything from disease diagnosis to crater counting. Coming to a clinic near youIn April, the U.S. Food and Drug Administration permitted marketing of the first artificial intelligence that diagnoses health problems at primary care clinics without specialist supervision (SN: 3/31/18, p. 15). ...

What will be the big science stories of 2019? Here are our predictions

Entire disciplines are devoted to predicting the future. Trained forecasters use data, trends, human behavior and more to predict what lies ahead. Exactly no one at Science News is a quantitative forecaster or futurist. But we do hear what scientists are buzzing about at meetings, on social media and while reporting stories. So when we ...

A new quantum engine packs more power than its standard counterparts

For the first time, a quantum engine has outperformed its traditional equivalent, without any special tweaks to its environment. The device harnesses the weird physics of very small objects to produce more power than a standard, or classical, engine under the same conditions, scientists report in the March 22 Physical Review Letters. “They’ve shown very ...

In ‘The Perfect Predator,’ viruses vanquish a deadly superbug

Epidemiologist Steffanie Strathdee and her husband, Thomas Patterson, went to Egypt in 2015 expecting to come home with some photos and souvenirs. Instead, Patterson was hit with his own version of the 10 plagues. At first, doctors in Egypt thought Patterson had pancreatitis. But his health worsened after treatment, and he started hallucinating. Once flown ... Read more

The LIGO and Virgo gravitational wave detectors are back on

It’s open season in scientists’ hunt for gravitational waves. A trio of detectors are back on the lookout for the ripples in spacetime. And the newly souped-up machines could make this the most productive search yet. The two detectors of the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, located in Hanford, Wash., and Livingston, La., and ... Read more

This Greek philosopher had the right idea, just too few elements

Long before there was a periodic table of the elements, there was no need for a table — just four chairs. From ancient through medieval into early modern times, natural philosophers could count the known elements with the fingers of only one hand (with no need for the thumb). All material reality, nearly every authority ... Read more

Metal asteroids may have once had iron-spewing volcanoes

Imagine a metal asteroid spewing molten iron, and you’ve got the gist of ferrovolcanism — a new type of planetary activity proposed recently by two research teams. When NASA launches a probe to a metal asteroid called Psyche in 2022, planetary scientists will be able to search for signs of such volcanic activity in the ... Read more
