Researchers Control Light Emission by Pairing Exotic 2D Materials

Researchers Control Light Emission by Pairing 2D Materials

By applying a DC voltage to layers of graphene and boron nitride, researchers have demonstrated the ability to control light emission from a nearby atom. Researchers have found a way to couple the properties of different two-dimensional materials to provide an exceptional degree of control over light waves. They say this has the potential to […]

Yale Researchers Illuminate Major Evolutionary Patterns of Snakes

Researchers Generate a Family Tree for Living and Extinct Snakes

A team of researchers from Yale University analyzed snake genomes, modern snake anatomy, and information from the fossil record, generating a family tree for living and extinct snakes and illuminating major evolutionary patterns that have played out across snake evolutionary history. The ancestral snakes in the grass actually lived in the forest, according to the […]

Brain Activity Predicts Weight Gain

New Study Shows How the Brain Responds to Food Cues

A new study set to appear in The Journal Neuroscience illustrates that it is the way the brain responds to food cues when individuals are not hungry that predicts weight gain and that the reasons why people gain weight can be fundamentally different. The way the brain responds while sipping a delicious milkshake can predict […]

New Image Shows the Advance of Hubbard Glacier

The Hubbard Glacier

New data from the Operational Land Imager on Landsat 8 shows the advance of Hubbard Glacier. Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. This image, acquired by […]

Opah – The First Fully Warm-Blooded Fish

New Research Reveals Opah as the First Warm-Blooded Fish

A newly published study reveals details about the opah – the first fully warm-blooded fish that circulates heated blood throughout its body. New research by NOAA Fisheries has revealed the opah, or moonfish, as the first fully warm-blooded fish that circulates heated blood throughout its body much like mammals and birds, giving it a competitive […]

MESSENGER Collects Important Data on Mercury during Its Orbital Decay

MESSENGER Collects Data on Mercury During Its Orbital Decay

NASA’s MESSENGER spacecraft collected low-altitude magnetic field measurements during its orbital decay, revealing that magnetism generated by the Mercury’s core dates to the very early history of the planet. Providence, Rhode Island (Brown University) — Though the MESSENGER mission to Mercury ended late last month with a planned collision into the planet’s surface, analysis of […]

Drug-Resistant EGFR May Have “Achilles Heel”

Two Experimental Drugs Show Promise Against Drug-Resistant EGFR

Researchers from Yale University have discovered a key structural difference in the drug-resistant form of EGFR that could lead to new strategies to combat the disease. Drugs introduced more than a decade ago that target mutations in a protein known as the epidermal growth factor receptor (EGFR) held the promise of personalized treatments for a […]

Evidence of a New Type of Star Cluster

Evidence for a Dark Side to NGC5128

Using data from ESO’s Very Large Telescope, astronomers have discovered a new class of “dark” globular star clusters around Centaurus A. These star clusters contain much more mass and may either harbor unexpected amounts of dark matter, or contain massive black holes. Globular star clusters are huge balls of thousands of stars that orbit most […]

Optimal Size and Shape Results in Better Medical Implants

Optimal Size and Shape Improve Implantable Devices

In a newly published study, scientists from MIT reveal that the geometry of implantable devices has a significant impact on how well the body will tolerate them. Biomedical devices that can be implanted in the body for drug delivery, tissue engineering, or sensing can help improve treatment for many diseases. However, such devices are often […]

New Chemical Catalysts Are Less Expensive and More Sustainable

New Chemical Catalysts

Researchers from Yale University have developed a new family of chemical catalysts that are expected to lower the cost and boost the sustainability of the production of chemical compounds used by a number of industries. The new catalysts are based on palladium, a rare and expensive metal. Palladium catalysts are used to form an array […]

Cassini Views Saturn’s Moon Janus

Cassini Image of Janus

This image from the Cassini spacecraft shows Saturn’s moon Janus at a distance of approximately 2.5 million kilometers. Although Janus should be the least lonely of all moons – sharing its orbit with Epimetheus – it still spends most of its orbit far from other moons, alone in the vastness of space. Janus (111 miles […]

Hubble Image of the Week – Tangled NGC 6240

Hubble Revisits Galaxy NGC 6240

First viewed in 2008, this Hubble image shows galaxy NGC 6240. Not all galaxies are neatly shaped, as this new NASA/ESA Hubble Space Telescope image of NGC 6240 clearly demonstrates. Hubble previously released an image of this galaxy back in 2008, but the knotted region, shown here in a pinky-red hue at the center of […]

A Promising New Treatment for Multiple Sclerosis

Researchers Solve Multiple Sclerosis Puzzle

New research shows that auto-reactive T cells in MS patients produce different types of inflammatory hormones called cytokines than they do in healthy subjects, opening the door to new treatments for the disease. Evidence has long suggested multiple sclerosis (MS) is an autoimmune disease, but researchers have been puzzled because they found the same T […]

New Mathematical Model Helps Predicts Optimal Use of Antibiotics

Mathematical Model Predicts Optimal Use of Antibiotics

Researchers at the Yale School of Public Health have developed a new mathematical model to help predict the optimal dosing of antibiotics. Although antibiotics were first introduced more than 70 years ago, substantial uncertainty remains about how the drugs should be used by patients to ensure recovery, while minimizing toxic side effects and the risk […]

Gene Expression Evolves Best Under a House-of-Cards Model

Gene Expression Evolves Under a House-of-Cards Model

Using sophisticated modeling of genomic data from diverse species, scientists from Yale University have answered a longstanding question about which competing model of evolution works best. Their research suggests that the “house of cards” model — which holds that mutations with large effects effectively reshuffle the genomic deck — explains evolutionary processes better than the […]

Kepler Observes Neptune and Its Moons Triton and Nereid

Kepler Observes Neptune and Its Moons

Seventy days worth of solar system observations from NASA’s Kepler spacecraft, taken during its reinvented “K2″ mission, are highlighted in this sped-up movie. The planet Neptune appears on day 15, followed by its moon Triton, which looks small and faint. Keen-eyed observers can also spot Neptune’s tiny moon Nereid at day 24. Neptune is not […]
