Plasma Irregularities in the Polar Ionosphere Can Distort GPS Signals

Study of Atmospheric Froth May Help GPS Communications

New research from scientists at NASA’s Jet Propulsion Laboratory and at the University of New Brunswick looks at irregularities in the ionosphere, comparing turbulence in the auroral region to that at higher latitudes. When you don’t know how to get to an unfamiliar place, you probably rely on a smart phone or other device with […]

A Possible Solution to the Mystery of the Origin of Matter in the Universe

New Image of the Pillars of Creation

A new study from UCLA physicists offers a possible solution to the mystery of the origin of matter in the universe. Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very […]

Antifreeze Protein Fights Frostbite in Mice

Antifreeze Protein Fights Frostbite

A new study from Yale University shows that a protein that protects ticks from freezing temperatures also prevents frostbite when introduced in mice. This is the first study to demonstrate the protein’s ability to boost frostbite resistance in an adult mammal. The research was published February 25 in the journal PLOS ONE. Several animal species, […]

NASA’s Curiosity Rover Drills at ‘Telegraph Peak’

Curiosity Rover Drills at Telegraph Peak

NASA’s Curiosity Mars rover drilled a small hole on February 24 to collect sample powder from inside a rock target called “Telegraph Peak,” which is located within the basal layer of Mount Sharp. The target sits in the upper portion of “Pahrump Hills,” an outcrop the mission has been investigating for five months. The Pahrump […]

Chandra Discovers Intermediate-Mass Black Hole in Spiral Galaxy NGC 2276

Astronomers Discover a New Object in Galaxy NGC 2276

Using NASA’s Chandra X-ray Observatory, astronomers have discovered a newly cosmic object that may help provide answers to some long-standing questions about how black holes evolve and influence their surroundings. “In paleontology, the discovery of certain fossils can help scientists fill in the evolutionary gaps between different dinosaurs,” said Mar Mezcua of the Harvard-Smithsonian Center […]

Nova Delphini 2013 Produces a Large Amount of Lithium

Classical Nova Explosions are Major Lithium Factories in the Universe

Using the 8.2-meter Subaru Telescope High Dispersion Spectrograph (HDS), a team of astronomers observed Nova Delphini 2013 and discovered that the outburst is producing a large amount of lithium. A team of astronomers from National Astronomical Observatory of Japan (NAOJ), Osaka Kyoiku University, Nagoya University, and Kyoto Sangyo University observed Nova Delphini 2013 (Figure 1, […]

Chemical Engineers Design New Self-Healing Hydrogel for Drug Delivery

New Self-healing Nanogel for Drug Delivery

Chemical engineers from MIT have designed a new type of self-healing hydrogel that consists of a mesh network made of two components: nanoparticles made of polymers entwined within strands of another polymer, such as cellulose. Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to […]

New Form of Quantum Friction Observed

Yale Physicists Discover a New Form of Quantum Friction

Physicists at Yale University have observed a new form of quantum friction that could open new avenues in the fields of nonlinear quantum optics and quantum information, where systems with multi-dimensional steady state manifolds can be used as error corrected logical qubits. The researchers have experimentally confined the state of a harmonic oscillator to the […]

An Unusual Comet Skimmed Past the Sun

SOHO Sees New Comet

A new comet was discovered sling-shotting around the sun by ESA/NASA’s SOHO. The comet is not from any known family of comets. An comet circles around the sun in this movie from ESA/NASA’s SOHO. The comet is somewhat unusual as it’s not form any known family of comets. This is the 2,875th comet discovered by […]

Dawn Spacecraft Shows Crater Shapes on Ceres’ Surface

New Images of Dwarf Planet Ceres

These new images from NASA’s Dawn spacecraft show the full range of different crater shapes that can be found at Ceres’ surface: From shallow, flattish craters to those with peaks at their centers. Dwarf planet Ceres continues to puzzle scientists as NASA’s Dawn spacecraft gets closer to being captured into orbit around the object. The […]

Painkillers with Fewer Side Effects

Paving the Way for Painkillers with Fewer Side Effects

Scientists at the SLAC National Accelerator Laboratory are paving the way for a new generation of pain relievers with reduced dependency. Researchers have long sought alternatives to morphine – a powerful and widely used painkiller – that curb its side effects, including dependency, nausea and dizziness. Now, an experiment at the Department of Energy’s SLAC […]

New Technique Could Enable Low-Cost Silicon Devices in Fibers

New Approach Could Enable Low-Cost Silicon Devices in Fibers

In a newly published study, researchers from MIT detail a new inexpensive approach to generating silicon-core fibers. Scientists have known how to draw thin fibers from bulk materials for decades. But a new approach to that old method, developed by researchers at MIT, could lead to a whole new way of making high-quality fiber-based electronic […]

Yale Study: Climate Science Communication and the Measurement Problem

Climate Science Literacy Unrelated to Public Acceptance of Human-Caused Global Warming

New research from Yale University shows that climate science literacy is unrelated to public acceptance of human-caused global warming. Deep public divisions over climate change are unrelated to differences in how well ordinary citizens understand scientific evidence on global warming, according to a new study published by Professor Dan Kahan. In fact, members of the […]
