Before CarPlay, Apple previewed ‘iOS in the Car’ with a very different design
CarPlay has graduated from a niche upgrade option to a mainstream standard feature in new cars, replacing clunky radio user interfaces with a design very familiar for iPhone users. But before Apple set CarPlay loose in the wild, the world was shown a.....»»
Radio waves can tune up bacteria to become life-saving medicines
Scientists from Australia and the United States have found a new way to alter the DNA of bacterial cells—a process used to make many vital medicines including insulin—much more efficiently than standard industry techniques......»»
How "the strong force" influences the gravitational wave background
Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe......»»
Could fiber optic cable help scientists probe the deep layers of the moon?
An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the moon, and what would it tell us about the deep layers of our nearest neighbor in space?.....»»
Nature"s sonar: Scientists reveal how Japanese horseshoe bats perceive moving objects
Unlike most animals that rely on visual senses, bats navigate and locate prey or obstacles through echolocation. By emitting sounds and comparing them to the reflected echoes, bats can "visualize" movement in the environment. When sound waves encount.....»»
African great apes predicted to see frequent extreme climate events in the next 30 years
African apes are already being exposed to climate change impacts, and will experience extreme events such as wildfires, heat waves and flooding more frequently in the next 30 years, according to a study published February 28 in the open-access journa.....»»
Humanity Is Dangerously Pushing Its Ability to Tolerate Heat
Extreme heat waves are already here, and they are killing tens of thousands of people. Blasting through 2 degrees Celsius of warming means they’ll happen many times more frequently......»»
Researchers leverage machine learning to improve space weather predictions
There are three levels of severity for space storms: geomagnetic storms, solar radiation storms and radio blackouts. These storms produce different effects on Earth, including satellite, GPS, communications and electrical grid issues, as well as heal.....»»
Tsunami on the plains: Researchers find that sea waves once swept Canadian Prairie Provinces
Hundreds of millions of years ago, an earthquake sent a series of massive waves across the ancient sea that covered part of Western Canada and the northern United States......»»
Meltwater in the north Atlantic can lead to European summer heat waves, study finds
Scientists from the National Oceanography Centre (NOC) have discovered that increased meltwater in the North Atlantic can trigger a chain of events leading to hotter and drier European summers......»»
Step aside, internal tides: Supercomputer modeling improves satellite altimetry precision
Waves don't take place just on the ocean's surface. Underneath the crests and troughs that we can see from above are internal tides, which form when tidal flows collide with seamounts, continental slopes, and ridges on the seafloor......»»
Observations explore radio jet of a powerful quasar
European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties of this jet, sugges.....»»
