Swarms of orbiting sensors could map an asteroid"s surface
It seems like every month a new story appears announcing the discovery of thousands of new asteroids. Tracking these small body objects from ground and even space-based telescopes helps follow their overall trajectory. But understanding what they're.....»»
Basketball"s legend credits Apple Watch"s persistence for making him see a heart doctor
It was only after repeated warnings of atrial fibrilliation from his Apple Watch that basketball legend Sean Elliott sought help and had essential treatment.Apple Watch health monitoringThe heart rate sensors in Apple Watch have previously helped peo.....»»
Researchers use vibrations from traffic to measure underground soil moisture
Caltech researchers have developed a new method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. This region, called the vadose zone, is crucial for plants and crops to obtain water through the.....»»
Oceans without sharks would be far less healthy, says new research
There are more than 500 species of sharks in the world's oceans, from the 7-inch dwarf lantern shark to whale sharks that can grow to over 35 feet long. They're found from polar waters to the equator, at the water's surface and miles deep, in the ope.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»

How duplicated genomes helped grasses diversify and thrive
Grasses cover about 40% of the Earth's land surface, thriving in a multitude of environments. The evolutionary success of this plant family, which includes rice, maize, wheat and bamboo, likely results from a history of whole-genome duplications, acc.....»»
Mass extinction 66 million years ago triggered rapid evolution of bird genomes, study finds
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began......»»

NASA smacked a spacecraft into an asteroid—and learned details about its 12-million-year history
NASA's DART mission—Double Asteroid Redirection Test—was humanity's first real-world planetary defense mission......»»
DART mission sheds new light on target binary asteroid system
In studying data collected from NASA's DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission's science team has discovered new information on the ori.....»»
Researchers develop general framework for designing quantum sensors
Researchers from North Carolina State University and the Massachusetts Institute of Technology have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to.....»»
Hybrids between two species can produce “swarms” that flourish
Humans may be part of a hybrid swarm. And we’re making more of them. Enlarge (credit: Aurich Lawson | Getty Images) There are no wild ligers. Indeed, hybrids were once thought to be rare in nature—and of little conse.....»»
Imaging below the surface reveals one of Los Angeles"s webs of faults
A major fault is often surrounded by a web of secondary faults created as the forces that cause slip deform nearby rocks. This damage zone can act as a record of fault activity, but what we can learn from it—such as how the fault may behave during.....»»
Has NASA found evidence of ancient life of Mars? An expert examines the latest discovery
NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be detected by the Perseverance rover, as well as curious discolored spots that could indicate th.....»»
NASA, JAXA bounce laser beam between moon"s surface and lunar orbit
NASA's LRO (Lunar Reconnaissance Orbiter) has twice transmitted a laser pulse to a cookie-sized retroreflector aboard JAXA's (Japan Aerospace Exploration Agency) SLIM lander on the moon and received a return signal......»»
Integrating active and passive microwave satellite data yields more precise global soil moisture mapping
Researchers from the Aerospace Information Research Institute of the Chinese Academy of Sciences, in partnership with international colleagues, made strides in mapping surface soil moisture across the globe. They combined data from two advanced satel.....»»
Why the solar corona is so much hotter than sun"s surface
In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provi.....»»
Surface Pro 11 review: just buy it
The Surface Pro 11 is the best Surface Pro ever made. It’s also the ever made. Heck, I might even say it has some serious advantages over the . It’s buoyed by the new Snapdragon X chip, first and foremost. But it also has a new webcam, im.....»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
