Science Daily Reports

Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al. used recently detected marsquakes from the seismometer deployed during the InSight mission to map the interior of Mars (see the Perspective by Cottaar and Koelemeijer). Mars likely has…

In 2016, the residents of Isle de Jean Charles, a small strip of land off the coast of Louisiana, received a $48 million grant to relocate their entire community. Faced with sea level rise and rapid erosion, many made the decision to seek higher ground. Communities around the world—from Miami to Mumbai—will have to grapple with similar choices.

Science News Video: Underwater robot may unearth climate mysteries


Related Videos On: Underwater robot may unearth climate mysteries


Two hundred meters under the sunny waves of the ocean lies the mesopelagic zone, a cold, dark section of water where humans rarely venture. This area, dubbed the “twilight zone” houses animals like krill, squid, and jellyfish. Twilight zone animals play a major part in the carbon cycle, bringing organic carbon from surface waters and trapping them deep beneath the tides. But these shy creatures are delicate and hard to observe, making it nearly impossible to trace their movements, let alone their impact on the Earth’s climate. Enter Mesobot. This autonomous underwater robot weighs in at just over 550 pounds, with a black and yellow tank-like exterior. It can track a single organism for over a day without human intervention, relying on a long-lasting battery and advanced tracking algorithms to follow creatures on their daily commutes. With an array of sensors and a high-definition camera, Mesobot could help scientists learn about this mysterious ocean area—and the creatures it contains. Read the research: https://scim.ag/3jGxGD8

Related Videos On: Your body’s ‘hidden’ senses might help treat epilepsy, depression


When it comes to our senses, we frequently focus on the external—the crack of thunder, the glare of sunlight, the fragrance of flowers—that captured our attention in the first place. But our bodies also have a whole host of internal senses that tell our brains whether our hearts are beating at the right speed, for example, or whether our blood pressure is too high. These signals travel constantly via hormones and nerves, including a mysterious 100,000-fiber network called the vagus nerve. Now, new techniques are helping scientists map the thin, twisting branches of the vagus nerve—which connects the brain to the heart, intestines, and other internal organs—and make surprising discoveries about its role in memory and emotion.

Humans have been observing stars for centuries, but the methods scientists have to calculate a star’s age aren’t as exact as you’d think. Here we walk through three strategies: Hertzsprung-Russell diagrams, rotation rates and asteroseismology.

Related Videos On: Cells’ hairlike cilia may keep coronavirus out of the lungs | Science News


Normally, cilia move in synchronized waves to push mucus away from the lungs, toward the throat where foreign objects are swallowed. But coronavirus-infected cells lose those cilia and no longer push mucus, eliminating a barrier that would normally help prevent the virus from invading the lungs. Here microscopic beads move around the surface of uninfected lab-grown cells first and then around infected cells, illustrating mucus movement. The colored lines show how fast the beads are moving, with blue indicating slower speeds and red noting faster speeds.

Winter on the Qinghai-Tibetan Plateau is a hard time for pikas. Temperatures fall below –30° Celsius and food becomes scarce. But in areas where yak and pika overlap, these rabbitlike mammals survive through winter on yak feces. Scientists think the danger of picking up parasites or pathogens from eating poo are outweighed by the benefits of having an abundant, easily digestible source of food when times get tough.
