For the first time, scientists from Lawrence Livermore National Laboratory and five other organizations have shown that human influences significantly impact the size of the seasonal cycle of temperature in the lowest layer of the atmosphere.
Fossils of a new genus and species of an ankylosaurid dinosaur—Akainacephalus johnsoni-- have been unearthed in Grand Staircase-Escalante National Monument in southern Utah, U.S.A., and are revealing new details about the diversity and evolution of this group of armored dinosaurs.
In a study that challenges scientists preconceptions about the global carbon cycle, researchers find that tiny organisms deep in the ocean's twilight zone may play an outsize part in the circulation of carbon.
Fish that ‘farm’ their own patches of seaweed alter their ‘cropping’ practices under high CO2 conditions, researchers at the University of Adelaide in Australia have found.
Using ancient dog DNA and DNA from modern village dogs, University of Michigan researchers find new genetic sites that may be responsible for important domestication traits--sites that are also connected to rare genetic syndromes in people.
Those cute little whiskers you see on your pet do more than just twitch adorably. Intrigued by the hairs’ versatility, University of Texas at Dallas researchers used shape-memory polymers to create artificial, electronic versions called e-whiskers, which mimic the properties of the real thing.
A new University of Washington-led paper pinpoints starvation as the cause of death for hundreds of thousands of Cassin's auklet seabirds in late 2014 to early 2015.
A new study that reconstructs the deep history of our planet’s relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around its axis.
A study in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.
Sweet potatoes may seem as American as Thanksgiving, but scientists have long debated whether their plant family originated in the Old or New World. New research by an Indiana University paleobotanist suggests it originated in Asia, and much earlier than previously known.
A team of researchers led by Lawrence Livermore National Laboratory has developed a second way to use protein markers from human tissue to identify people – this time from human bones.
Harvard Medical School researchers lead the first whole-genome analysis of ancient human DNA from Southeast Asia Study identifies at least three major waves of human migration into the region over the last 50,000 years, each shaping the genetics of Southeast Asia “to a remarkable extent” Findings reveal a complex interplay among archaeology, genetics and language
The Clarkson Student Projects for Engineering Experience and Design Team won 1st place in a regional competition.
Scientists are now working to take cloaking devices from the dramatic realm of science fiction and make them real. Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the wave energy, concealing the object from the sound waves. During the 175th ASA Meeting, Hanford will describe the physics behind an underwater acoustic shield designed in her lab.
A group of researchers announced April 26 in Nature that they had managed to entangle perhaps the largest items yet, at a whopping 20 microns across—about the diameter of a single human hair.
An international team, led by Berkeley Lab scientists, has demonstrated a breakthrough in the design and function of nanoparticles that could make solar panels more efficient by converting light usually missed by solar cells into usable energy.
DHS S&T recently used advanced DNA sequencing to determine the identity of a 4,000-year-old mummy head found in 1915, when American explorers entered an ancient tomb cut in the parched limestone cliffs of the eastern bank of the Nile River, 155 miles south of Cairo.
A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.
Researchers at Case Western Reserve University have cracked the evolutionary mystery of why chimpanzees and gorillas walk on their knuckles: The short explanation is that these African apes climb trees and they are mobile on the ground.
Scientists have designed a conceptual spacecraft to deflect Earth-bound asteroids and evaluated whether it would be able to nudge a massive asteroid – which has a remote chance to hitting Earth in 2135 – off course.
