A woman’s unusual vomiting episodes may be linked to an autoimmune disorder. A young woman experienced spontaneous vomiting attacks during which she would sometimes retch more than 30 times a day and heave up to 1.6 gallons (6 liters) over the full course of an episode. It turns out, theContinue Reading
The “most complicated therapy ever” tailors bespoke, genome-edited immune cells to attack tumors A small clinical trial has shown that researchers can use CRISPR gene editing to alter immune cells so that they will recognize mutated proteins specific to a person’s tumours. Those cells can then be safely set looseContinue Reading
Greek astronomer Hipparchus is thought to be the first to attempt to precisely map the stars Fragments of a star catalog from the second century B.C. have turned up in a manuscript that had been erased and written over centuries later. A new analysis of the religious manuscript shows thatContinue Reading
Your questions answered about what RSV is, how it spreads, what vaccines are on the way and who is most at risk As flu season picks up and experts weigh concerns about another possible COVID surge, children’s hospitals are already filling with patients with another viral threat: respiratory syncytial virus,Continue Reading
The finding, based on more than 1,000 quakes, suggests the planet isn’t geologically dead Researchers have analyzed a slew of recent temblors on the Red Planet and shown that these Marsquakes are probably caused by magma moving deep under the Martian surface. That’s evidence that Mars is still volcanically active,Continue Reading
Muons from cosmic rays might lead to a new tool for understanding the weather Particles raining down from space offer 3-D views inside swirling tropical storms. Muons created from cosmic rays that smash into Earth’s upper atmosphere have revealed the inner workings of cyclones over Japan, researchers report October 6Continue Reading
The curiosity of a high school student unraveled the nebula’s structure Roughly 3,000 light-years from Earth sits one of the most complex and least understood nebulae, a whirling landscape of gas and dust left in the wake of a star’s death throes. A new computer visualization reveals the 3-D structureContinue Reading
Four exceptional fossils represent newly described species. Just beneath the scrubby plains of southern North Dakota at the site of an ancient riverbed, paleontologists are hard at work digging up the end of the world as the dinosaurs knew it. Now, they’ve discovered two newfound species of 66 million-year-old sturgeonContinue Reading
If you’ve ever gazed up at the full moon, you might notice a face looking back at you: the so-called man in the moon. But why does our natural satellite seem to sport a face? Over billions of years, asteroid impact craters and the aftermath of lunar volcanic eruptions gaveContinue Reading
Geneticist Svante Pääbo figured out how to extract DNA from Neandertals’ and Denisovans’ bones Establishing a new field of science to answer the question of what makes humans unique from our extinct relatives has earned Svante Pääbo the Nobel Prize in physiology or medicine. “Humanity has always been intrigued byContinue Reading
