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 […]

NanoVelcro Device Grabs Single Cancer Cells from Blood

NanoVelcro Chip Grabs Single Cancer Cells from Blood

UCLA scientists have developed a NanoVelcro Chip that can detect and isolate single cancer cells from patient blood samples for analysis. Researchers at UCLA report that they have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients’ tumors and circulate in the blood. With the improvements to […]

Scientists Develop a Tool for Reading the Minds of Mice in Real-Time

A System for Observing Real-Time Brain Activity in a Live Mouse

Stanford scientists have developed a technique for observing real-time brain activity in live mice. The new tool may be useful in the fight against neurodegenerative diseases, such as Alzheimer’s. As the mouse explores the arena, neurons in its brain flash green when it recognizes a familiar spot. Courtesy of Mark Schnitzer If you want to […]

piRNAs Key Role in Coordinating Biological Activity

piRNAs Key Role in Coordinating Biological Activity

A team of Yale researchers discovered that specialized RNAs called piRNAs guide epigenetic factors to numerous sites throughout the genome of the fruit fly Drosophila, where these switches work to turn genes on or off. If a genome is the blueprint for life, then the chief architects are tiny slices of genetic material that orchestrate […]

Precambrian Micro-Continent Hidden in the Indian Ocean

Continents Hidden Under Lava in the Indian Ocean

Based on the study of lava sand grains from the beach of Mauritius, a newly published study from a group of geoscientists suggests that a micro-continent is hidden under lava in the Indian Ocean. The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment […]

Sideways Motions of Distant Stars Shed New Light on Milky Way Evolution

New Light on Milky Way Evolution

A team of astronomers used Hubble to precisely measure the sideways motions of a small sample of stars located far from the galaxy’s center, shedding new light on the evolution of the Milky Way. Peering deep into the vast stellar halo that envelops our Milky Way galaxy, astronomers using NASA’s Hubble Space Telescope have uncovered […]
