Episodios

  • End of 'Green Sahara' May Have Spurred a Megadrought in Southeast Asia

    27/08/2020 Duración: 02min

    That drought may have brought about societal shifts in the region 5,000 years ago. Christopher Intagliata reports.

  • White Rhinos Eavesdrop to Know Who's Who

    26/08/2020 Duración: 03min

    The finding could potentially help wildlife managers keep better tabs on their herds. Jason G. Goldman reports. 

  • Prehistoric Marine Reptile Died after a Giant Meal

    21/08/2020 Duración: 02min

    Researchers found extra bones within a 240-million-year-old ichthyosaur fossil—which they determined to be the ichthyosaur’s last, possibly fatal meal. Christopher Intagliata reports.

  • Cows with Eye Images Keep Predators in Arrears

    19/08/2020 Duración: 04min

    Butterflies, fish and frogs sport rear-end eyespots that reduce predation. Painting eye markings on cows similarly seems to ward off predators.

  • Warbler Species Fires Up Song Diversity

    18/08/2020 Duración: 03min

    Hermit warblers in California have developed 35 different song dialects, apparently as a result of wildfires temporarily driving them out of certain areas.

  • Why Lava Worlds Shine Brightly (It's Not the Lava)

    12/08/2020 Duración: 02min

    Scientists determined that “lava world” exoplanets do not derive their brightness from molten rock but possibly get it from reflective metallic clouds. Christopher Intagliata reports.

  • Aardvarks Are Ailing amid Heat and Drought

    11/08/2020 Duración: 03min

    Climate change is expected to bring more frequent droughts and heat waves to Africa’s Kalahari Desert. And aardvarks might not be able to cope. Jason G. Goldman reports.

  • The World's Highest-Dwelling Mammal Lives atop a Volcano

    07/08/2020 Duración: 02min

    Scientists spotted a mouse at the summit of Llullaillaco, a 22,000-foot-tall volcano on the border of Chile and Argentina. Julia Rosen reports.

  • Dampening of the Senses Is Linked to Dementia Risk

    05/08/2020 Duración: 01min

    A decline in smell was the sense loss most strongly associated with such risk in a recent study. Christopher Intagliata reports.

  • Translucent Frog Optics Create Camo Color

    04/08/2020 Duración: 04min

    Rather than undergoing active chameleonlike color changes, glass frogs’ translucency allows light to bounce from their background and go through them—making their apparent color close to their setting. 

  • Paired Comparisons Could Mean Better Witness Identifications

    03/08/2020 Duración: 02min

    Compared with traditional lineup techniques, a series of two-faces-at-a-time choices led to more accurate identification by study witnesses.

  • Foxes Have Dined on Our Leftovers for 30,000 Years

    02/08/2020 Duración: 02min

    An analysis of fox fossils found evidence that they scavenged from wolf and bear kills until Homo sapiens supplied plenty of horse and reindeer remains.

  • Mexico Caves Reveal Ancient Ocher Mining

    31/07/2020 Duración: 03min

    Now submerged caves in the Yucatán Peninsula contain remains of ocher-mining operations that date back at least 10,000 years.

  • In Bee Shortage, Bubbles Could Help Pollinate

    27/07/2020 Duración: 02min

    Soap bubbles are sticky enough to carry a pollen payload and delicate enough to land on flowers without harm.

  • Science News Briefs from around the Planet

    26/07/2020 Duración: 02min

    Here are some brief reports about science and technology from all over, including one about how a lizard population responded to hurricanes by developing larger and stickier toe pads on average.

  • Seismologists Find the World Quieted Down during Pandemic Lockdowns

    25/07/2020 Duración: 02min

    COVID-19-related lockdowns dampened human activity around the globe—giving seismologists a rare glimpse of the earth’s quietest rumblings. Christopher Intagliata reports.

  • Old Art Offers Agriculture Info

    24/07/2020 Duración: 04min

    Art museums are filled with centuries-old paintings with details of plants that today give us clues about evolution and breeding practices.

  • How COVID-19 Decreases Weather Forecast Accuracy

    23/07/2020 Duración: 02min

    Meteorologists take advantage of weather data collected by commercial jetliners at different altitudes and locations. Fewer flights mean less data.

  • Cricket Avoids Being Bat Food by Doing Nothing

    22/07/2020 Duración: 03min

    The sword-tailed cricket can discern bats’ echolocation signals by only responding to calls of a certain volume—at which point it plummets out of their approach.
