Homer-1 Could Be a Key to the Treatment of Stress-Induced Cognitive Deficits

Homer 1 Prevents Stress Induced Cognitive Deficits

In a soon to be published study, researchers from the Max Planck Institute show in mice that social stress reduces the volume of Homer-1 in the hippocampus, which results in impaired learning, and that it is possible to prevent the resulting cognitive deficit by administering additional volumes of Homer-1. Before examinations and in critical situations, […]

The Mercury Planetary Orbiter, One Step Closer to Takeoff

The Mercury Planetar Orbiter a Step Closer to its 2015 Launch

The Mercury Planetary Orbiter is one step closer to its 2015 launch, completing a “bake-out” where the sides and top of the chamber were kept heated to around 50°C, while the underside remained cooled by liquid nitrogen. The faint aroma of hot metal filled the surrounding cleanroom as the hatch to ESA’s newest test facility […]

A New Method for Observing High-Temperature Superconductors

A New Method for Observing the Motion of Electron Density Waves

A team of scientists from MIT and Brookhaven National Laboratory have found a new method to study fluctuating charge-density waves in a superconducting material, possibly leading to a better understanding of high-temperature superconductivity and new discoveries. While the phenomenon of superconductivity — in which some materials lose all resistance to electric currents at extremely low […]

New Holographic Technique May Lead to Restored Vision

New Holographic Technique Could Lead to Bionic Vision

A team of researchers from the Technion-Israel Institute of Technology are combining computer-generated holography and optogenetics in an effort to develop a new strategy for restoring vision. Computer-generated holography, they say, could be used in conjunction with a technique called optogenetics, which uses gene therapy to deliver light-sensitive proteins to damaged retinal nerve cells. In […]

Yale Researchers Identify Cells That Morph Into Body Fat

Study Reveals the Origins of Body Fat

While working with mice, Yale researchers used a process known as differentiation to successfully identified cells with certain types of receptors that could eventually morph into white adipocytes, the cells most people recognize as fat. Yale School of Medicine researchers have answered a question millions regularly and plaintively ask themselves: Where did all that fat […]

Study Shows Graphene is Highly Efficient in Converting Light to Electricity

Study Shows Graphene is Highly Efficient in Converting Light to Electricity

A newly published study shows that graphene is highly efficient in converting light to electricity, demonstrating that graphene is able to convert a single photon that it absorbs into multiple hot electrons, and that the higher photon’s energy, the larger the number of hot electrons created. The most recent addition to the long list of […]

Diagnosing the X-Ray Variability in NGC 4507

Diagnosing the X-Ray Variability of a Galaxy Nucleus

A group of astronomers used the Chandra and XMM-Newton satellites to study the X-ray variability of the active galaxy NGC 4507, finding that significant variations took place over timescales of months, which correspond to motions of gas clouds at distances of roughly a hundred light-years from the nucleus, and concluding that a single, universal structure […]

Mediterranean Diet Significantly Reduces the Risk of Suffering a Cardiovascular Death

Mediterranean Diet Reduces the Risk of Suffering a Cardiovascular Related Death

A new study from the University of Barcelona found that eating a Mediterranean diet supplemented with extra-virgin olive oil or tree nuts reduced the risk of suffering a cardiovascular related death by approximately 30 percent. The results of the study PREDIMED, aimed to assess the efficacy of the Mediterranean diet in the primary prevention of […]

Evidence of Extraterrestrial Life Might Come from Planets Orbiting White Dwarfs

Evidence of Extraterrestrial Life Might Come from Dying Stars

In a new study, researchers from the Harvard-Smithsonian Center for Astrophysics suggest that future evidence for extraterrestrial life might come from planets orbiting dying stars called white dwarfs. Cambridge, Massachusetts – Even dying stars could host planets with life – and if such life exists, we might be able to detect it within the next […]

Cassini Views Saturn’s North Polar Hexagon

The North Polar Hexagon of Saturn

Captured by Cassini’s wide-angle camera, this NASA image of the day shows Saturn’s North Polar Hexagon. Saturn’s North Polar Hexagon Saturn’s north polar hexagon basks in the Sun’s light now that spring has come to the northern hemisphere. Many smaller storms dot the north polar region and Saturn’s signature rings, which appear to disappear on […]

Hubble Image of Planetary Nebula ESO 456-67

Planetary Nebula ESO 456 67

This newly released image from the Hubble Space Telescope shows planetary nebula ESO 456-67. It may look like something from The Lord of the Rings, but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The […]
