What is the best radiation shielding for the surface of Mars?
The planet Mars is calling to us. At least, that is the impression one gets when examining all the planned and proposed missions to the red planet in the coming decade. With so many space agencies currently sending missions there to characterize its.....»»
A new robotic platform to reproduce and study complex ciliary behavior
Cilia are sensory structures extending from the surface of some cells. These hair-like structures are known to contribute to the sensorimotor capabilities of various living organisms, including humans......»»
Mars has ‘oceans’ worth’ of water – but it’s deep underground
Researchers have identified what they believe could be oceans' worth of water on Mars. There's just one snag: it's deep underground......»»
Researchers highlight the carbon-saving potential of compact cities
In recent years, the dramatic rise in extreme weather events due to climate change has escalated what was once termed "climate change" into a "climate crisis." With global average surface temperatures reaching unprecedented levels, the urgency to tra.....»»
Scientists find oceans of water on Mars. It"s just too deep to tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet's surface......»»
Mars and Jupiter get chummy in the night sky. The planets won"t get this close again until 2033
Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade......»»
Forecasters still predict highly active Atlantic hurricane season in mid-season update
Federal forecasters are still predicting a highly active Atlantic hurricane season thanks to near-record sea surface temperatures and the possibility of La Niña, officials said Thursday......»»
High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers
Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. How.....»»
Here"s how Curiosity"s sky crane changed the way NASA explores Mars
Twelve years ago, NASA landed its six-wheeled science lab using a daring new technology that lowers the rover using a robotic jetpack......»»
Model suggests spewing metal nanorods into Mars" atmosphere could warm the planet by 30 K
A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then.....»»
Science is Solving Iceland"s Dangerous Volcanic Mystery
We take you down below Iceland's erupting surface with the researchers who are trying to understand what's going to happen next......»»
New research challenges conventional wisdom on wet surface adhesion
Scientists at the University of Akron and the University of Pittsburgh have overturned long-held assumptions in new research that finds water can be a help for adhesion......»»
Using dental growth rings scientists reveal differences in growth patterns between ancient and modern mammals
A study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilized tooth roots, the researchers were ab.....»»
Optical navigation tech could streamline planetary exploration
In a dim, barren landscape like the surface of the moon, it can be easy to get lost. With few discernable landmarks to navigate with the naked eye, astronauts and rovers must rely on other means to plot a course......»»
South Florida estuaries warming faster than Gulf of Mexico, global ocean, research shows
Sea surface temperatures are on the rise around the world, but the problem is pronounced in South Florida, according to a series of studies published by researchers at the University of South Florida College of Marine Science......»»
Take a trip to the largest lake on Mars
Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA's Mars Express......»»
Using historical radar data to map changes in urban environments
Synthetic aperture radar (SAR) is a type of remote sensing from satellites that uses the reflection of radio waves to relay information about the surface of the earth. This reflection, or backscatter, is responsive to physical properties, such as rou.....»»
Machine learning and better radar solve the "cloud cover" problem
Clouds have for decades been a bugbear for remote sensing of land surface temperature—one of the most important earth system metrics, used in everything from tracking climate change to predicting wildfires. A new approach incorporating machine lear.....»»
Relive Mars rover’s ‘7 minutes of terror’ during landing 12 years ago
NASA has marked the 12th anniversary of Curiosity's arrival on Mars with a video that relives the remarkable effort to safely land the rover on the red planet......»»
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.....»»
