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 […]

Scientists Discover a New Kind of Extinct Flying Reptile

Eurazhdarcho Langendorfensis

Paleontologists have discovered the fossilized bones of a 68 million year old flying reptile, Eurazhdarcho langendorfensis, in the Transylvanian Basin of Romania. A new kind of pterosaur, a flying reptile from the time of the dinosaurs, has been identified by scientists from the Transylvanian Museum Society in Romania, the University of Southampton in the UK […]

A New Biologic Understanding of Breast Cancer Invasion and Metastasis

Cluster of Circulating Tumor Cells From a Breast Cancer Patient

A newly published study investigates the role of epithelial-mesenchymal transition, or EMT, with cancer progression and treatment response in breast cancer patients, providing researchers with a new biologic understanding of breast cancer invasion and metastasis. A process that normally occurs in developing embryos—the changing of one basic cell type into another—has also been suspected of […]

Study Suggests Super-Earths Are More Like Mini-Neptunes

Are Super Earths Mini Neptunes

A newly published study suggests that super-Earths are surrounded by extended hydrogen-rich envelopes and that they are more like mini-Neptunes than Earth. In the last two decades astronomers have found hundreds of planets in orbit around other stars. One type of these so-called ‘exoplanets’ is the super-Earths that are thought to have a high proportion […]

New Production Method Improves Quantum-Dot Performance

Improved Quantum Dot Performance

MIT scientists have developed a new process for creating quantum dots with four important qualities, high particle uniformity, high photoluminescence quantum yields, narrow and symmetric emission spectral lineshapes and minimal single-dot emission intermittency, which should result in improved quantum-dot performance. Quantum dots — tiny particles that emit light in a dazzling array of glowing colors […]

Researchers Move Closer to Preventing Alzheimer’s Disease

A Treatment to Prevent Alzheimers Disease is a Step Closer

Scientists at the University of Lancaster have developed a new drug that may help prevent the early stages of Alzheimer’s disease by reducing the number of senile plaques and increasing the number of new nerve cells in a region of the brain associated with memory. A new drug to prevent the early stages of Alzheimer’s […]

Researchers Find a New Target to Treat a Wide Spectrum of Cancers

New Target for Treating Wide Spectrum of Cancers

By using a computational method to capture the various shapes of the p53 protein, a protein that is implicated in nearly 40 percent of diagnosed cancer cases, scientists have identified a way to target the protein with cancer-fighting drugs. UC Irvine biologists, chemists and computer scientists have identified an elusive pocket on the surface of […]

Asteroid to Make a Record Close Approach to Earth on February 15

Passage of Asteroid 2012 DA14 Through the Earth Moon System

According to NASA data, a 45 meter asteroid named 2012 DA14 will make a record close approach for a known object of this size to Earth on February 15, passing inside the ring of geosynchronous weather and communications satellites. The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so […]

Hubble Views a Galaxy in a Transitional Phase

Young Star Forming Galaxies Settle to Become Massive Red and Dead Galaxies

The Hubble Space Telescope captured an image of the transitional phase when young, star-forming galaxies settle to become massive, red and dead galaxies. The further away you look, the further back in time you see. Astronomers use this fact to study the evolution of the Universe by looking at nearby and more distant galaxies and […]

An Updated Model for Identifying Habitable Zones Around Stars

A Model for Identifying Habitable Zones Around Stars

Scientists at Penn State have developed an updated model for determining whether discovered planets fall within a habitable zone. University Park, Pennsylvania — Researchers searching the galaxy for planets that could pass the litmus test of sustaining water-based life must find whether those planets fall in what’s known as a habitable zone. New work, led […]
