CERN Details New Observation of Matter-Antimatter Asymmetry

A new study from the LHCb collaboration at CERN details the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s, viewing a preference for matter over antimatter known as CP-violation in the decay of neutral B0s particles. The LHCb collaboration at CERN today submitted a paper to Physical Review [...]

Ancient DNA Reveals the First Detailed Genetic History of Modern Europe

An international team of researchers used ancient DNA to reconstruct the first high-resolution genetic record of modern European lineages through time, observing both human DNA evolving in ‘real-time’ and the dramatic population changes that have taken place in Europe. Ancient DNA recovered from a series of skeletons in central Germany up to 7500 years old [...]

One of the Most Efficient Star Making Galaxies Ever Observed

Using Hubble, WISE and the IRAM Plateau de Bure interferometer in the French Alps, astronomers viewed efficient star-making galaxy SDSSJ1506+54, seeing a rare phase of evolution that is the most extreme and most efficient yet observed. Astronomers have spotted the “greenest” of galaxies, one that converts fuel into stars with almost 100-percent efficiency. The findings [...]

Hubble Captures Close-Up View of Comet ISON

NASA’s Hubble telescope captured close-up images of Comet ISON in early April, providing scientists with images to measure the activity level of the comet. This NASA Hubble Space Telescope image of Comet (C/2012 S1) ISON was photographed on April 10, when the comet was slightly closer than Jupiter’s orbit at a distance of 386 million [...]

A Closer Look at the Antifreeze Protein that Allows Siberian Beetles to Survive

A newly published study from Yale University looks at longhorn beetle Rhagium inquisitor and its ability to supercool to below -25°C, examining the unusual structure of its antifreeze protein. In 2011, Yale undergraduates asked a question: How does a Siberian beetle survive some of the cruelest winters on earth? Their answer appears on the cover [...]

InGaAs Nanowires Grown on Graphene Have Unique Structure

Researchers at the University of Illinois at Urbana-Champaign have grown nanowires of the material indium gallium arsenide (InGaAs) on a sheet of graphene, discovering that InGaAs wires grown on graphene spontaneously segregate into an indium arsenide (InAs) core with an InGaAs shell around the outside of the wire. Champaign, Illinois — When a team of [...]

Antibody Transforms Bone Marrow Stem Cells Directly into Brain Cells

While looking for lab-grown antibodies that can activate a growth-stimulating receptor on marrow cells, a team of scientists at the Lerner lab discovered a way to turn bone marrow stem cells directly into brain cells. La Jolla, California – In a serendipitous discovery, scientists at The Scripps Research Institute (TSRI) have found a way to [...]

Measuring the Universe’s Rate of Expansion with Black Holes

By using certain types of active black holes that lie at the center of many galaxies, researchers have developed a method with the potential to measure distances of billions of light years with a high degree of accuracy. Radiation emitted in the vicinity of black holes could be used to measure distances of billions of [...]

Herschel Solves Mystery of Origin of Water in the Upper Atmosphere of Jupiter

Using the Herschel space observatory, researchers have solved the mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the impact of comet Shoemaker-Levy 9 in 1994. Astronomers have finally found direct proof that almost all water present in Jupiter’s stratosphere was delivered by [...]

Four Minute Video Shows Three Years of SDO Images

NASA’s Solar Dynamics Observatory has had consistent coverage of the sun’s rise toward solar maximum since 2010 and now that data has been compressed into a four minute video at a pace of two images per day. In the three years since it first provided images of the sun in the spring of 2010, NASA’s [...]

Anle138b Slows Down the Onset and Progression of Parkinson’s Disease

Researchers have developed a chemical compound, Anle138b, that prevents clumping of synunclein protein, slowing down the onset and progression of Parkinson’s disease in mice. The earliest signs of Parkinson’s disease can be deceptively mild. The first thing that movie star Michael J. Fox noticed was twitching of the little finger of his left hand. For [...]
