A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that underlies the sound made when you blow across the top of an empty bottle. Experiments using baby powder to map the flow of air,…
About 18 years ago, a 4-year-old girl with a rare nerve cell cancer received an infusion of immune cells that were genetically engineered to fight the disease. Since then, she has remained cancer-free, possibly making her the longest-surviving patient with cancer who received this tailored treatment, researchers report February 17 in Nature Medicine. As part…
The first generation of stars in the universe could have produced significant amounts of water upon their deaths, just 100 million to 200 million years after the Big Bang. Signatures of water have previously been observed some 780 million years after the Big Bang. But now, computer simulations suggest that this essential condition for life…
After brain surgery, Jon Nelson and other volunteers are tasked with rehabbing their brain. This job is harder than it might seem, as people re-learn how to navigate the world with a range of emotions that they haven’t felt in a long time. We’ll hear from a psychologist who describes the shift from day-to-day survival…
BOSTON —Droplets of Venus’ clouds may someday come to Earth. Researchers are testing a device that can gather mist from our planetary neighbor’s atmosphere and deliver it to scientists so they can test the samples for signs of life. Venus is not an obvious place to look for life. Its globe-spanning cloud decks are made…
Even as Texas grapples with a measles outbreak that has already left one child dead, the childhood vaccination schedule is coming under new scrutiny by the Trump administration. The recommended list of immunizations starting at birth protects kids against more than a dozen deadly diseases from measles to whooping cough. U.S. Health and Human Services…
