Examining the Fundamentals of Desirable Nanotubes

Armchair Carbon Nanotubes

A newly published study provides scientists with a valuable resource for detailed information about metallic carbon nanotubes. The first fruits of a cooperative venture between scientists at Rice University and the National Institute of Standards and Technology (NIST) have appeared in a paper that brings together a wealth of information for those who wish to […]

Triangular Layers of Tungsten Disulfide May Have Applications in Optical Technology

Light Emitting Triangles

Researchers at Penn State have created triangular single layers of tungsten disulfide that exhibit unusual photoluminescent properties and may have potential applications in optical technology. For the first time, scientists have created single layers of a naturally occurring rare mineral called tungstenite, or WS2. The resulting sheet of stacked sulfur and tungsten atoms forms a […]

Earth-like Planets May Have Older and More Evolved Life

Habitable Planet With Two Moons Orbiting a Red Dwarf Star

Astronomers at the Harvard-Smithsonian Center for Astrophysics believe that six percent of red dwarf stars have habitable, Earth-sized planets. Since red dwarfs live much longer than Sun-like stars, this discovery raises the possibility that some of these planets may have much older and more evolved life than on Earth. Cambridge, Massachusetts – Using publicly available […]

Vitamin D3 and Omega-3 May Help Fight Alzheimer’s

Vitamin D3 and Omega 3 Fatty Acids May Help Fight Alzheimer's Disease

New research from the David Geffen School of Medicine at UCLA shows how vitamin D3 and omega-3 fatty acids may enhance the immune system’s ability to clear the brain of amyloid plaques, shedding further light on a possible role for nutritional substances in boosting immunity to help fight Alzheimer’s disease. A team of academic researchers […]

WISE Views the Orion Nebula

Orion Nebula

NASA’s Wide-field Infrared Survey Explorer (WISE) captured a new view of the Orion nebula and the tangle of clouds and stars that lie in Orion’s sword. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying […]

Nanosensors Check if Replacement Cells are Still Alive

PH Nanosensor Based Magnetic Resonance Imaging Technique

Using a pH-nanosensor-based magnetic resonance imaging (MRI) technique, scientists at John Hopkins have developed a method to detect whether cells previously transplanted into a living animal are alive or dead. Researchers at Johns Hopkins have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they […]

Unique Features of Spiral Galaxy Messier 106

Spiral Galaxy M 106

Located about 20 million light-years away, spiral galaxy M 106 has several unique features: instead of two spiral arms, it appears to have four and as gas spirals towards the black hole at its center, it heats up and emits powerful, bright microwave radiation. The NASA/ESA Hubble Space Telescope – with a little help from […]

XMM-Newton Study of Zeta Puppis Provides New Details on Stellar Winds

Highly Fragmented Stellar Wind

Three published papers detail the long-term XMM-Newton study of zeta Puppis and provide the first constraints on the number of fragments in a stellar wind from a massive star. ESA’s XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it […]

Attention Deficits Discovered in Babies Who Later Develop Autism

Researchers Spot Attention Deficits in Babies Who Later Develop Autism

While studying both high-risk and low-risk infants for developing autism, Yale University researchers found that the infants later diagnosed with ASD showed signs of decreased spontaneous attention to social scenes. Researchers at Yale School of Medicine are able to detect deficits in social attention in infants as young as six months of age who later […]

Scientists Synthesize the First Biologically Effective Perfume

Formula for a Biologically Effective Perfume

Scientists from the Max Planck Institute discovered that women prefer the smell of men who have different immune gene variants than they themselves have, cracking the olfactory code for partner selection and synthesizing the first biologically effective perfume. Individual body odor plays an important role in partner selection. Humans, mice, fish and birds, and probably […]

3-D Printing of Human Embryonic Stem Cell Cultures

Printed Human Organs for Testing and Transplantation

Researchers from Heriot-Watt University, in partnership with Roslin Cellab, have developed a 3D printing process that is the first to print embryonic cell cultures, allowing them to create more accurate human tissue models that are essential to in vitro drug development and toxicity-testing. A specialized 3D printing process, using human stem cells, could pave the […]
