Episodes

Gut Microbes Help Keep Starved Flies Fecund  

Microbes living in the guts of fruit flies appear to influence the flies' food choice—and promote egg production, even under a nutrient-poor diet. Christopher Intagliata reports.

Selective Breeding Molds Foxes Into Pets  

Evolutionary biologist Lee Dugatkin talks about the six-decade Siberian experiment with foxes that has revealed details about domestication in general.  

Why One Researcher Marched For Science  

Lisa Klein, from the materials science and engineering department at Rutgers University, commented on the March For Science at an April 21st talk to the chemistry department at Lehman College in the Bronx.  

Healthy Behavior Can Spread Like Illness  

If people run more in New York City, that can push their socially connected counterparts in San Diego to run more as well. Christopher Intagliata reports.

Climate 420 Million Years Ago Poised for Comeback  

Starting in the next century, atmospheric carbon levels could begin to approach those of hundreds of millions of years ago, and have their warming effect augmented by a brighter sun. 

Traces of Genetic Trauma Can Be Tweaked  

Trauma can be passed down to offspring due to epigenetic changes in DNA. But positive experiences seem able to correct that. Erika Beras reports. 

Species Split When Mountains Rise  

Plant species in China's Hengduan Mountains exploded in diversity eight million years ago—right when the mountains were built. Christopher Intagliata reports. 

Shoelace Study Untangles a Knotty Problem  

Researchers have trotted out data that show that a combination of whipping and stomping forces is what causes laces to unravel without warning. Karen Hopkin reports.

World Parkinson's Day Puts Spotlight on Condition  

Michael J. Fox Foundation for Parkinson's Research CEO Todd Sherer, a neuroscientist, talks about the state of Parkinson's Disease and research.

Cave Dwellers Battled Bed Bug Bites, Too  

Researchers have found the earliest evidence of bugs in the Cimex genus co-habitating with humans, in Oregon's Paisley Caves. Christopher Intagliata reports. 

Extreme Storms are Extreme Eroders  

The storm that swept across the Rockies in September 2013 unleashed huge amounts of sediment downstream, doing the work of a century of erosion. Julia Rosen reports.

Exoplanets Make Life Conversation Livelier

Bring Bronx Zoo To Your Living Room  

Animal Planet's series The Zoo shows viewers the biological, veterinary and conservation science at a modern zoo.  

UV Rays Strip Small Galaxies of Star Stuff  

Researchers measured the intensity of the universe's ultraviolet background radiation, and say it may be strong enough to strip small galaxies of star-forming gas. Christopher Intagliata reports.

Aggressed-Upon Monkeys Take Revenge on Aggressor's Cronies  

Japanese macaques at the receiving end of aggression tend to then take it out on a close associate or family member of the original aggressor.  

Chaotic Orbits Could Cause Catastrophic Collision  

Researchers used ancient climate cycles to confirm the solar system’s chaotic planetary orbits. An Earth-Mars collision is one distant outcome. Julia Rosen reports.

Pulling the String on Yo-Yo Weight Gain  

Mice that lost weight and then gained back more than they lost maintained an obesity-type microbiome that affected biochemicals involved in either burning or adding fat--suggesting interventions.  

Poverty Shaves Years Off Life  

A meta-analysis found that being of low-socioeconomic status was associated with almost as many years of lost life as was a sedentary lifestyle.
