One thing leads to another. It sounds obvious, but in the quantum realm, the saying doesn’t always ring true. A new quantum device can jumble up a sequence of two events so that they take place in both orders simultaneously, researchers report in a paper in press in Physical Review Letters. “In everyday life, we […]

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 […]

Skulls seem solid, but the thick bones are actually riddled with tiny tunnels. Microscopic channels cut through the skull bones of people and mice, scientists found. In mice, inflammatory immune cells use these previously hidden channels to travel from the bone marrow of the skull to the brain, the team reports August 27 in Nature […]

The days of the great Pacific garbage patch may be numbered. A highly anticipated project to scoop up plastic from the massive pool of ocean debris is poised to launch its first phase from Alameda, Calif., on September 8. The creators of the project, called the Ocean Cleanup, say their system can remove 90 percent […]

A natural history museum isn’t just a place to take visiting relatives or for entertaining kids on the weekends. These museums’ collections also play a vital, but under-celebrated, role in scientific research. That’s why, when Brazil’s National Museum in Rio de Janeiro caught fire on September 2, more than just a catalog of natural and […]

In movies and TV shows, Tyrannosaurus rex often sports a fleet of big, sharp teeth that are almost always on display. But the dinosaurs and their kin may have kept their pearly whites mostly tucked behind lizardlike lips. Similar to Komodo dragons today, these dinosaurs had ample soft tissue around the mouth that would have […]

Indigenous knowledge and Western science have written a new tale about when horses most recently arrived in North America. Spaniards brought horses to Mexico in 1519. Indigenous peoples then took the reins, rapidly transporting offspring of those equine newcomers north along trade routes. As a result, a new study finds, many Native American populations across […]

Waves of cerebrospinal fluid which normally wash over brains during sleep can be made to pulse in the brains of people who are wide awake, a new study finds. The clear fluid may flush out harmful waste, such as the sticky proteins that accumulate in Alzheimer’s disease (SN: 7/15/18). So being able to control the […]

The only cure to being drunk is to wait it out. But that might not always be the case: Injecting drunk mice with a naturally occurring hormone helped them sober up more quickly than they otherwise would have, a new study shows. Mice that received a shot of FGF21 — a hormone made by the […]

Astrophysicist Erika Nesvold once asked an executive of a company aiming to mine the moon how he planned to address risks that mining equipment might carry microbes from Earth and contaminate the moon (SN: 1/10/18). His response: “We’ll worry about that later.” That’s a reckless mind-set when it comes to preparing for people to live […]
