    Better hurricane forecasts and spotting salts on Jupiter’s moon Europa
    We’ve all seen images or animations of hurricanes that color code the wind speeds inside the whirling mass—but it turns out we can do a better job measuring these winds and, as a result, better predict the path of the storm. Staff Writer Paul Voosen talks with host Sarah Crespi about how a microsatellite-based project for measuring hurricane wind speeds is showing signs of success—despite unexpected obstacles from the U.S. military’s tweaking of GPS signals.    Also this week, Sarah talks with graduate student Samantha Trumbo, a Ph.D. candidate in planetary science at the California Institute of Technology in Pasadena, about spotting chloride salts on the surface of Jupiter’s moon Europa. What can these salts on the surface tell us about the oceans that lie beneath Europa’s icy crust? Download a transcript (PDF)  This week’s episode was edited by Podigy.

    The limits on human endurance, and a new type of LED
    Cheap and easy to make, perovskite minerals have become the wonder material of solar energy. Now, scientists are turning from using perovskites to capture light to using them to emit it. Staff Writer Robert Service joins host Sarah Crespi to talk about using these minerals in all kinds of light-emitting diodes, from cellphones to flat screen TVs. Read the related paper in Science Advances. Also this week, Sarah talks with Caitlin Thurber, a biologist at Nassau Community College in Garden City, New York, about a hard limit on human endurance. Her group used data from transcontinental racers—who ran 957 kilometers over the course of 20 weeks—and found that after about 100 days, their metabolism settled in at about 2.5 times the baseline rate, suggesting a hard limit on human endurance at long timescales. Earlier studies based on the 23-day Tour de France found much higher levels of energy expenditure, in the four- to five-times-baseline range.

    Grad schools dropping the GRE requirement and AIs play capture the flag
    Up until this year, most U.S. graduate programs in the sciences required the General Record Examination from applicants. But concerns about what the test scores actually say about potential students and the worry that the cost is a barrier to many have led to a rapid and dramatic reduction in the number of programs requiring the test. Science Staff Writer Katie Langin joins host Sarah Crespi to talk about this trend and how it differs across disciplines. Also this week, Sarah talks with DeepMind’s Max Jaderberg in London about training artificial agents to play a video game version of capture the flag. The agents played approximately 4 years’ worth of Quake III Arena and came out better than even expert human players at both cooperating and collaborating, even when their computer-quick reflexes were hampered. And in this month’s book segment, new host Kiki Sanford interviews Marcus Du Satoy about his book The Creativity Code: Art and Innovation in the Age of AI. This week’s episode was edited by Podigy.

    New targets for the world’s biggest atom smasher and wood designed to cool buildings
    The Large Hadron Collider (LHC) was built with one big goal in mind: to find the Higgs boson. It did just that in 2012. But the question on many physicists’ minds about the LHC is, “What have you done for me lately?” Host Sarah Crespi talks with Staff Writer Adrian Cho about proposals to look at the showers of particles created by its proton collisions in new ways—from changing which events are recorded, to changing how the data are analyzed, even building more detectors outside of the LHC proper—all in the hopes that strange, longer-lived particles are being generated but missed by the current set up. Also this week, Sarah talks with Tian Li of the University of Maryland in College Park about a modified wood designed to passively cool buildings. Starting from its humble roots in the forest, the wood is given a makeover: First it is bleached white to eliminate pigments that absorb light. Next, it is hot pressed, which adds strength and durability. Most importantly, these processes allow the wood to emit in the middle-infrared range, so that when facing the sky, heat passes through the wood out to the giant heat sink of outer space.
