Graphene Quantum Dots Outperform Platinum in Fuel Cells

Graphene Quantum Dots Form Catalyst for Fuel Cells

Researchers at Rice University have developed a cheap hybrid catalyst made from graphene quantum dots that outperforms platinum catalysts for certain reactions within fuel cells. Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, […]

New Drug-Delivery Capsule to Inject Drugs Directly into the Lining of the Digestive Tract

New Drug Delivery Capsule Can Deliver Drugs Directly into the Lining of the Digestive Tract

Researchers at Massachusetts General Hospital and MIT have developed a new drug-delivery capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after the capsule is swallowed. Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, especially those […]

New SDO Video Shows Recent Sunspots that Have Developed and Faded Away

New SDO Video Shows Recent Sunspots

This new video from the Solar Dynamics Observatory shows how many sunspots develop and fade away over a period of days. Lots of Spots Over the past month (August 25 – September 25, 2014) the Sun has produced quite a few sunspot groups, with some of them being significantly large. Sunspots are darker, cooler areas […]

NASA’s Swift Detects a Massive Superflare from a Red Dwarf Star

Swift Detects a Massive Superflare from a Red Dwarf Star

NASA’s Swift satellite detected a massive superflare from a red dwarf star in the binary system DG CVn. The initial blast was as much as 10,000 times more powerful than the largest solar flare ever recorded and reached temperatures of 360 million degrees Fahrenheit (200 million Celsius), more than 12 times hotter than the center […]

ALMA Finds Direct Evidence That Merging Galaxies Can Form Disc Galaxies

New Observations Explain Why Milky Way Like Galaxies Are so Common

Using the Atacama Large Millimeter/sub-millimeter Array (ALMA) and several other radio telescopes, astronomers find direct evidence that merging galaxies can form disc galaxies instead of elliptical galaxies. For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using ALMA and a host […]

Resveratrol Inhibits the Growth of Bacteria that Causes Acne

Researchers Reveal Resveratrol May Weaken Bacteria

New research shows that resveratrol may be a key ingredient for acne treatment, finding that combining resveratrol with a common acne medication, benzoyl peroxide, may enhance the drug’s ability to kill the bacteria and could translate into new treatments. Got grapes? UCLA researchers have demonstrated how resveratrol, an antioxidant derived from grapes and found in […]

Scientists Reveal New Information to Improve Vaccinations Against Pneumococcus Infection

Scientists Reveal Six Changing Faces of Pneumococcus Infection

An international team of experts has revealed a genetic switch that controls pneumococcus infection and allows the bacterium to randomly change its characteristics into six alternative states. This research could pave the way to improved vaccines. Every ten seconds a human being dies from Streptococcus pneumoniae infection, also known as pneumococcus, making it a leading […]

Architecture of Kepler’s Multi-Transiting Systems

Architecture of Planetary Systems

A new study details the orbital architectures of Kepler systems having multiple planet candidates, revealing 899 transiting planet candidates in 365 multiple-planet systems and providing a powerful means to study the statistical properties of planetary systems. There are 1822 confirmed exoplanets reported so far, and NASA’s Kepler satellite has found evidence for more than two […]

Cassini Reveals Mysterious Feature off the Coast of Ligeia Mare

Cassini Data Show Mysterious Feature in Ligeia Mare

New images from Cassini data show the appearance and evolution of a mysterious feature in Ligeia Mare, one of the largest hydrocarbon seas on Saturn’s moon Titan. The views, taken during three different Cassini flybys of Titan, show that this feature was not visible in earlier radar images of the same region and its appearance […]

How Tiny Imbalances Result in Massive Phytoplankton Blooms

Ocean Data Shows Plankton Movement

New research details how tiny imbalances in the phytoplankton predator-prey relationship, caused by environmental variability, give rise to massive phytoplankton blooms, having huge impacts on ocean productivity, fisheries and carbon cycling. The greens and blues of the ocean color from NASA satellite data have provided new insights into how climate and ecosystem processes affect the […]

Supercomputer Simulations Reveal an Unusual Death for Ancient Supermassive Stars

Astrophysicists Reveal An Unusual Death for Ancient Stars

New supercomputer simulations show that non-rotating supermassive primordial stars can die as highly energetic thermonuclear supernovae powered by explosive helium burning, releasing about 10,000 times the energy of a Type Ia supernova and leaving no compact remnant. Certain primordial stars—those between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died […]

New ‘Cloaking’ Device Uses Ordinary Lenses to Hide Objects

Simple Cloaking Device Uses Ordinary Lenses to Hide Objects

Using a combination of four standard lenses, researchers at the University of Rochester have developed a “cloaking” device that hides objects when you look at them straight on. Inspired perhaps by Harry Potter’s invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed […]
