Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...
Could the secret to preventing dangerous falls be surprisingly simple? For older adults, these unexpected tumbles are a leading cause of injury, affecting roughly 1 in 4 people 65 and older each year. What if the key isn't ...
Many animals exhibit fascinating collective behaviors, which allow them to move, search for food, reproduce and avoid threats more effectively than they would alone. One of these behaviors is queuing migration, which essentially ...
When female bottlenose dolphins want to avoid males known for pushy mating behaviors, they listen out for their unique signature whistles. That's the suggestion of a study published in Proceedings of the National Academy ...
Most of the earthquakes we hear about are due to tectonic plates colliding or sliding past each other near plate boundaries. Yet researchers have detected some enigmatic earthquakes happening inside the more stable interiors ...
We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...
In a strong El Niño winter, normally dry regions can suddenly drown in rain. NASA notes that "typically dry regions can experience nearly two times as much rain during a strong El Niño." Indeed, the blockbuster El Niños of ...
Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal ...
Italian astronomers have used the Very Large Telescope (VLT) to perform polarimetric observations of the star WRAY 15-1880 and its young circumstellar disk. Results of the new observations, presented June 10 on the arXiv ...
Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct ...
