Exploring Graphene-Based THz Devices
Future communication devices may get a big boost in efficiency from terahertz waves and graphene. In a newly published study, scientists at the University of Notre Dame have shown that it is possible to manipulate THz electromagnetic waves with thin layers of graphene. People use electromagnetic energy every day … watching television, listening to the [...]

Corkscrew Lava Coils Seen on Mars in Athabasca Valles
NASA’s HiRISE spacecraft, which is currently orbiting Mars, spotted these interesting patterns, which are actually rare lava flows. This is the first time that lava flows have been seen on Mars, and the corkscrew snail shell-like patterns are indicative of previous volcanic activity. The formations are in an area called Athabasca Valles, which is a [...]

Resveratrol Interacts with SIRT1 Gene for Health Benefits
New research from Harvard Medical School shows that resveratrol, a compound found in red wine, interacts with a key gene in mitochondria, providing prolonged lifespan and activity of mitochondria. Using genetically enhanced mice, the study shows that mice cells lacking the SIRT1 gene don’t respond to resveratrol, while mice with the gene showed dramatic increases [...]

Pigeons Ability to Hear Magnetic Fields Finally Linked to the Lagena in Inner Ear
New research has showed that the individual neurons in the brains of common pigeons could relay crucial information about the Earth’s magnetic field, potentially providing these animals with an internal GPS. The research in magnetoreception was published in the journal Science, and it shows that individual cells seem to encode information on a magnetic field’s [...]

4D Imaging of Breathing Lungs
A new 4D dynamic functional lung imaging method developed by engineers at Monash University will allow health professionals a chance to study breathing lungs in unprecedented detail. The device uses high-speed video captured by a very bright, high quality X-ray, resulting in a detailed map of lung function. A new lung imaging method has the [...]

Columbia Glacier Retreating to the Sea in Alaska
It took seven years, but the photographic record of the Columbia Glacier in Prince William Sound on Alaska’s southern central Pacific coast has been compiled into a time-lapse video that documents the glacier’s rapid ice discharge. This is helping researchers to understand better how tidewater glaciers are contributing to seal-level rise. The video itself was [...]

APEX Provides Images of Dust near Orion’s Belt
New images captured by Atacama Pathfinder Experiment telescope show clouds of cosmic dust threaded through the nebula Messier 78. The images were created by overlaying the APEX observations on a visible-light image in orange, allowing astronomers a closer look for studying the dusty clouds in which stars are born. Dust may sound boring and uninteresting [...]

Human Evolution Still Tied to Darwinian Selection
As it turns out, even with all our medical technology and health education, we can’t outrun the findings of Charles Darwin. A study conducted by an international collaboration of scientists shows that humans are continuing to evolve just like other species in the wild. New evidence proves humans are continuing to evolve and that significant [...]

Astronomers Discover Large Group of Rogue Stars
As scientists are learning more about rogue stars, they are also learning new ways to locate them. A new study from astronomers at Vanderbilt University reports that they have identified a group of more than 675 stars on the outskirts of the Milky Way that they believe to be hypervelocity stars ejected from the galactic [...]

Inexpensive Strategies Linked to Lowering Heart Attack Mortality Rates
Examining the substantial variations in mortality rates from heart attack patients in hospitals across the United States led Yale researchers to find relatively inexpensive strategies that could lower mortality rates and open the door for improvement in heart attack treatment nationally. Reviewing heart attack cases during monthly meetings with emergency medical services and maintaining a [...]
