Listeners also share their experiences and remedies.
Over the past two decades, rates of peanut allergies in children have more than tripled. A variety of theories has been proposed to explain this, from a rise in industrialization keeping kids away from the germs that develop the immune system, to the previous pediatric guidelines that urged parents to restrict access to peanuts early in life. Whatever the cause, higher rates of peanut allergies means effective treatments are in higher demand. New research published in NEJM Evidence shows that a ...

Certain words are overrepresented in text written by AI language models. A study investigates why such patterns develop. Also, the ends of chromosomes, called telomeres, typically shorten as an organism ages. But when some fat-tail dwarf lemurs hibernate, they lengthen. ‘Delving’ Into The ‘Realm’ Of AI Word Choice Several years ago, some eagle-eyed readers of scientific papers noticed an unusual trend —an increase in the number of abstracts using certain words. The terms, including “delve,” “rea...
TB kills more than a million people each year. Dr. Mireille Kamariza has spent her career developing better detection and treatment tools. As the United States retreats from global health leadership—withdrawing from the World Health Organization, dismantling USAID—public health experts warn that there will be implications for the spread of certain diseases around the globe.

In a new book, author John Green traces how the disease has impacted culture, geography, and even fashion over the centuries. Tuberculosis (TB) has had an incredibly large impact on human history. One staggering statistic? It’s been estimated that by the start of the 1800s, the disease had killed one in seven people who had ever lived. Because of this, tuberculosis affected human culture, geography, and fashion—and even killed off some of literature and media’s most famous heroines. While TB inc...
Researchers built the largest 3D map of our universe yet. What they found supports the idea that dark energy could have evolved over time. One of the mysteries of the universe is why it expands at the rate that it does. Back in 1998, two teams of researchers observed that not only was the universe expanding, but that the rate of expansion was increasing . That observation was the basis for a concept now known as dark energy. In the years since, cosmologists have been trying to get a handle on be...

In the 1980s, Dr. Vincent Felitti ran a weight loss clinic in San Diego, California. He noticed that some patients who re...
Former NIH director Dr. Harold Varmus speaks out about what recent budget cuts and policy changes could mean for science. One of the areas targeted by President Trump’s administration for cuts has been the National Institutes of Health (NIH). Cost-cutting actions have included the layoffs of some 1,200 NIH employees, the termination of research grants , a pause in the “study sections” that evaluate and award grant funding, and a cap on indirect costs included in research grants. Some of those mo...
