New Titius-Bode-Based Exoplanet Predictions – 2 Planets in the Habitable Zone of Each Star

Scientists Predict Earth-Like Planets around Most Stars

Using the Titius-Bode relation and Kepler data, astronomers from Australian National University estimate that the standard star has about two planets in the habitable zone. Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life. The new research, led by PhD student Tim Bovaird and […]

Crystal Boundaries Can Enhance, or Reduce, Hydrogen Embrittlement

Analysis Shows How to Prevent Metal Embrittlement

A newly published study from MIT details how certain crystal boundaries can enhance, or reduce, the damaging effects that lead to metal embrittlement. When a metal tube lines an oil well thousands of feet below the surface of the ocean, that metal had better be solid and reliable. Unfortunately, the environment in such deep wells […]

New Research Shows Seizures Knock Out Brain Arousal Centers

Seizures Knock Out Brain Arousal Centers

Researchers from Yale University found that during seizures the arousal centers in the brain stem are actually suppressed, leading to a loss of consciousness. People with epilepsy who experience focal seizures sometimes remain mobile but are unable to hear or respond to their environment. Yale School of Medicine researchers have discovered a surprising explanation for […]

Hubble Views Three Moons Transiting the Face of Jupiter

Hubble Views Jupiter Triple-Moon Conjunction

Taken with Hubble’s Wide Field Camera 3 in visible light, these new images capture the rare occurrence of three of Jupiter’s largest moons (Europa, Callisto, and Io) racing across the banded face of the gas-giant planet. These so-called Galilean moons, named after the 17th century scientist Galileo Galilei, who discovered them with a telescope, complete […]

New Horizons Returns New Images of Pluto

New Image of Pluto

Headed towards Pluto, NASA’s New Horizons spacecraft has captured this new image of Pluto and its moon Charon. NASA’s New Horizons spacecraft returned its first new images of Pluto on Wednesday, as the probe closes in on the dwarf planet. Although still just a dot along with its largest moon, Charon, the images come on […]

NASA’s Dawn Spacecraft Gets a Closer View of Ceres

Dawn Gets Closer Views of Ceres

NASA’s Dawn spacecraft has acquired its latest and closest-yet snapshot of Ceres. At a resolution of 8.5 miles (14 kilometers) per pixel, the pictures represent the sharpest images to date of Ceres. After the spacecraft arrives and enters into orbit around the dwarf planet, it will study the intriguing world in great detail. Ceres, with […]

VISTA Views the Trifid Nebula and Reveals Previously Hidden Objects

VISTA Views the Trifid Nebula

A newly released image taken from ESO’s VISTA survey telescope shows the Trifid Nebula and reveals hidden variable stars. By observing in infrared light, astronomers can see right through the dust-filled central parts of the Milky Way and spot many previously hidden objects. In just this tiny part of one of the VISTA surveys, astronomers […]

Astronomers Identify New Details in Spiral Galaxy M51a

New Details in First Known Spiral Galaxy

Using CWRU’s Burrell Schmidt telescope at KPNO, astronomers identify two new tidal streams extending from the northeast and south of the nearby spiral galaxy M51a. Case Western Reserve University astronomers peered deep into space to discover new features of a galaxy that’s been sketched and photographed for 170 years. The researchers were able to see […]

Brain Scans Help Reveal How the Brain Ignores Distractions

How the Brain Ignores Distractions

By scanning the brains of people engaged in selective attention to sensations, researchers from Brown University have learned how the brain appears to coordinate the response needed to ignore distractions. Providence, Rhode Island (Brown University) — When we concentrate on something, we also engage in the unsung, parallel act of purposefully ignoring other things. A […]

High-Speed Images Reveal How Raindrops Spread Pathogens Among Plants

How Raindrops Spread Pathogens Among Plants

A new theoretical model describes the relationship between a leaf’s flexibility, the fragmentation of the fluid, and its resulting pattern of raindrop-induced dispersal. Using high-speed images of raindrops splashing down on leaves, the researchers show that raindrops can act as a dispersing agent of contaminated droplets from one plant to another. Historical weather records suggest […]

Nutritional Supplements Help Ease Clinical Depression

Nutritional Supplements Ease Clinical Depression

A new review of the literature evaluated the findings of nearly 200 published papers that studied the effectiveness of five nutritional supplements on depression, revealing that nutritional supplements appear to ease clinical depression. People suffering from clinical depression appear to be helped by regularly taking nutritional supplements such as vitamin B. A new review of […]

Researchers Uncover Genetic Trigger for Immune Response

Yale Uncovers Genetic Trigger for Immune Response

Yale researchers have identified an unexpected relationship between mtDNA and the innate immune response, showing a new source of inflammation that could promote common diseases and aging. The thousands of mitochondrial DNA (mtDNA) molecules present in each cell are known primarily for their role converting food and oxygen into energy. But Yale researchers have identified […]

BICEP2/Keck Find No Conclusive Evidence of Gravitational Waves from Early Universe

Early Universe Gravitational Waves Remain Elusive

A new analysis of data has found no conclusive evidence of gravitational waves from the early universe, showing that much of the signal detected by BICEP2/Keck is coming from dust in the Milky Way. A joint analysis of data from the Planck space mission and the ground-based experiment BICEP2 has found no conclusive evidence of […]

The Spitzer Interacting Galaxies Survey: An Infrared Atlas of Interacting Galaxies

Interacting Galaxies M51A and M51B

Astronomers from the Harvard-Smithsonian Center for Astrophysics report that, when compared with non-interacting field galaxies, the star formation rate does indeed increase in merging spirals, but that the efficiency of star formation does not appear to increase much as the merger progresses, at least in this limited sample. Most galaxies, including our own Milky Way, […]

Dancing on the Edge – Hubble Views Spiral Galaxy NGC 7814

Hubble Telescope Views NGC 7814

This newly released Hubble image shows spiral galaxy NGC 7814. Galaxies can take many shapes and be oriented any way relative to us in the sky. This can make it hard to figure out their actual morphology, as a galaxy can look very different from different viewpoints. A special case is when we are lucky […]

New Technique Extends Duration of Quantum States

New Technique Greatly Extends Duration of Fragile Quantum States

Using a qubit design that employs nitrogen atoms embedded in synthetic diamond, a team of researchers has developed a new technique that greatly extends duration of fragile quantum states. Quantum computers are experimental devices that promise exponential speedups on some computational problems. Where a bit in a classical computer can represent either a 0 or […]

3D Map of Core-Collapse Supernova Remnant Cassiopeia A

Nearby Supernova Remnant Reveals Frothy Interior

New research from the Harvard-Smithsonian Center for Astrophysics reveals near-infrared observations of the young Milky Way supernova remnant Cassiopeia A and a three-dimensional map of its interior. Cambridge, Massachusetts – Cassiopeia A, or Cas A for short, is one of the most well studied supernova remnants in our galaxy. But it still holds major surprises. […]
