Study Shows Low level Drinking Not Associated with Higher Risk of Poor Birth Outcomes

Low Level Drinking Not Associated with Higher Risk of Birth Defects

Newly published research shows that low to moderate alcohol consumption during pregnancy is not associated with an increased risk of specific birth outcomes and measures of fetal growth. Heavy alcohol consumption during pregnancy has long been linked to a range of developmental problems and birth defects including fetal alcohol syndrome (FAS), low birth weight, and […]

Hubble Views a Slashing Smudge Across the Sky

New Hubble Image of Dwarf Galaxy UGC 1281

This newly released Hubble images shows dwarf galaxy UGC 1281 and galaxy PGC 6700. The galaxy cutting dramatically across the frame of this NASA/ESA Hubble Space Telescope image is a slightly warped dwarf galaxy known as UGC 1281. Seen here from an edge-on perspective, this galaxy lies roughly 18 million light-years away in the constellation […]

Scientists Estimate the Magnetic Moment of Exoplanet HD 209458b

Scientists Estimate the Magnetic Field of an Exoplanet

A team of scientists has developed a new method that allows them to estimate the magnetic field of a distant exoplanets. Using this method they managed to estimate the value of the magnetic moment of the planet HD 209458b. In the two decades which passed since the discovery of the first planet outside the Solar […]

Geologists Discover Ancient Buried Canyon Along the Yarlung Tsangpo River

Yarlung Tsangpo Valley close to the Tsangpo Gorge

The new discovery a deep canyon buried along the Yarlung Tsangpo River in south Tibet effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast. A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon […]

White Matter Changes Allow Older People to Learn New Visual Tasks

White Matter Changes Allow Older Brains to Learn

New research from Brown University shows that older people can learn a visual task just as well as younger ones, revealing that a significant change in the white matter of the brain takes place when the older subjects learn. Providence, Rhode Island (Brown University) — A widely presumed problem of aging is that the brain […]

New 2D Materials Exhibit Exotic Quantum Properties

2D Quantum Materials Exhibit Quantum Spin Hall Effect

A newly published study from MIT details a theoretical analysis showing that a family of two-dimensional materials exhibits exotic quantum properties that may enable a new type of nanoscale electronics. These materials are predicted to show a phenomenon called the quantum spin Hall (QSH) effect, and belong to a class of materials known as transition […]

Scientists Use Meteorite to Measure Ancient Solar Nebula Magnetic Fields

Solar Nebula Magnetic Fields Recorded in the Semarkona Meteorite

Scientists from the Harvard-Smithsonian Center for Astrophysics have succeeded in determining ancient solar nebula magnetic field strength by measuring the field recorded in chondrules from the Semarkona meteorite. Astronomical observations of young protostars indicate that early planetary systems evolved from the dust in a protoplanetary disk very quickly – in under five million years. Such […]

Researchers Pinpoint Common Culprits for Autoimmunity in Plants

Overzealous Plant Immune System Can Be Deadly

Scientists from the Max Planck Institute for Developmental Biology have now pinpointed the most common culprits for autoimmunity in plants. Plants are under permanent attack by a multitude of pathogens. To win the battle against fungi, bacteria, viruses and other pathogens, they have developed a complex and effective immune system. And just as in humans, […]

Engineers Use Voltage to Control Magnetic Memory

Researchers Control a Material with Voltage

New research details how a MIT-based team has made important strides in the concept of using an electrical signal to control a magnetic memory. A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a […]

New Chandra Images Detail Supernova Remnants

Chandra Image of Supernova Remnant MSH 11-62

New observations from NASA’s Chandra X-ray Observatory reveal details of supernova remnant MSH 11-62 and G327.1-1.1. A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of high-energy […]

NASA’s Swift Discovers an Unusual Source of Light

High-Resolution Images of Markarian 177 and SDSS1133

Using data from NASA’s Swift satellite and observations from many other facilities, an international team of astronomers has discovered an unusual source of light in a galaxy some 90 million light-years away. The object’s curious properties make it a good match for a supermassive black hole ejected from its home galaxy after merging with another […]

Study Investigates Interaction between the Higgs Particle and Gravity

Gravity May Have Saved the Universe

A newly published study details how the spacetime curvature provided the stability needed for the universe to survive after the Big Bang. Studies of the Higgs particle – discovered at CERN in 2012 and responsible for giving mass to all particles – have suggested that the production of Higgs particles during the accelerating expansion of […]
