On May 12, 2013, the sun emitted a significant solar flare, peaking at 10 p.m. EDT. This flare is classified as an X1.7, making it the first X-class flare of 2013. The flare was also associated with another solar phenomenon, called a coronal mass ejection (CME) that can send solar material out into space. This CME was not Earth-directed. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the ...

New Rochelle, NY, May 13, 2013—New approaches to applying noninvasive imaging tests such as computed tomography (CT), magnetic resonance (MR), and positron emission tomography (PET) may play a bigger role in evaluating and managing patients with diabetes. Advances in noninvasive imaging technology can assess important changes in fat composition and distribution in the body that may affect the metabolic complications and diseases associated with diabetes, including cardiovascular disease and cancer. A forward-looking Review article on "Obesity and Diabetes: Newer Concepts ...

This news release is available in German. They promise to do their bit for the environment and stick eco labels on their products. But sooner or later someone will point out that they sell products that are pesticide-ridden or that contain palm oil sourced from endangered rainforests. Did the entrepreneurs reach their decision after a rational cost/benefit analysis? Or does unconscious behavior play a bigger role in entrepreneurial decision-making than is often assumed? What are the triggers that cause entrepreneurs to act against their own values? To find the answers ...

CLEMSON, S.C. — Although knowing an actor is gay significantly affected ratings of his masculinity, there was no significant effect on ratings of his acting performance, researchers say. A team of researchers tested the hypothesis claimed by recent news columns that an "out" actor cannot convincingly play a heterosexual because knowing someone is gay will bias perceptions of his or her performance. Led by Paul Merritt, a professor in the psychology department at Clemson University, the researchers published their findings in the journal Psychology of Popular Media Culture. "Early ...

Earthquakes similar in magnitude to the 2004 Sumatra earthquake could occur in an area beneath the Arabian Sea at the Makran subduction zone, according to recent research published in Geophysical Research Letters. The research was carried out by scientists from the University of Southampton based at the National Oceanography Centre Southampton (NOCS), and the Pacific Geoscience Centre, Natural Resources Canada. The study suggests that the risk from undersea earthquakes and associated tsunami in this area of the Western Indian Ocean – which could threaten the coastlines ...

Some parts of the body, like the liver, can regenerate themselves after damage. But others, such as our nervous system, are considered either irreparable or slow to recover, leaving thousands with a lifetime of pain, limited mobility, or even paralysis. Now a team of Tel Aviv University researchers, including Dr. Shimon Rochkind of TAU's Sackler Faculty of Medicine and Tel Aviv Sourasky Medical Center and Prof. Zvi Nevo of TAU's Department of Human Molecular Genetics and Biochemistry have invented a method for repairing damaged peripheral nerves. Through a biodegradable ...

People are worse at predicting whether a sports team will win, lose, or tie when they bet on the final score than when they bet on the overall outcome, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. Examining sports betting data from both the real world and the lab, psychological scientist Kwanho Suk and colleagues at Korea University Business School found that people who relied on more detailed information were actually less accurate in their predictions about sports match outcomes. These results ...

Researchers from Uppsala University in Sweden can now reveal the mechanism behind the curved path of a curling stone. The discovery by the researchers, who usually study friction and wear in industrial and technical applications, is now published in the scientific journal Wear. In the curling sport, the players shoot their stones along the ice so that they slowly slide towards the target area, almost 30 m away. The game has its name from the slightly curved "curled" path taken by the stone, when released with a slow rotation. This curled path is important since it is ...

New York University physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires, a finding that has the potential to deepen our understanding of self-sustained chemical reactions. The study, which appears in the journal Physical Review Letters, also included researchers from the University of Barcelona, City College of New York, and the University of Florida. It may be downloaded here: http://bit.ly/18FKwFO. Forest fires spread because an initial flame or spark will heat a substance—a trunk or ...

The first tropical cyclone in the Northern Indian Ocean this season has been getting better organized as seen in NASA satellite imagery. Tropical Cyclone Mahasen is projected to track north through the Bay of Bengal and make landfall later this week. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Mahasen in the Northern Indian Ocean on May 15 at 07:55 UTC (3:55 a.m. EDT). The image was created by NASA's MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, ...

Tropical Cyclone Jamala ran into some harsh atmospheric conditions on May 11 in the Southern Indian Ocean and vertical wind shear tore the storm apart. NASA's Aqua satellite captured an image of the remnants while the more powerful, more organized Tropical Cyclone Mahasen continued to strengthen to the north. When NASA's Aqua satellite flew over the Indian Ocean on May 13 at 0747 UTC (3:47 a.m. EDT), the Atmospheric Infrared Sounder (AIRS) instrument captured an image of both the remnants of Tropical Cyclone Jamala in the Southern Indian Ocean, and Tropical Cyclone Mahasen ...

Today's image of southern Australia showing New South Wales and Victoria shows a series of controlled fires. Fires are often deliberately set by fire officials and controlled in order to clean out dry underbrush and accumulations of debris. The fire burns away the detritus which could otherwise be the ignition for a devastating bushfire that may easily get out of control. In this image, it appears all of the fires have been planned and are under control. This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard ...

Copenhagen, Denmark – Climate change could dramatically reduce the geographic ranges of thousands of common plant and animal species during this century, according to research using data made freely available online through the Global Biodiversity Information Facility (GBIF). Research published today in the journal Nature Climate Change looked at nearly 50,000 globally widespread and common species and found that nearly two-thirds of the plants and almost half of animal species could lose more than half of their climatic range by 2080 if nothing is done to limit greenhouse ...

Researchers from the RIKEN Center for Integrative Medical Sciences in Japan have identified the first gene to be associated with adolescent idiopathic scoliosis (also called AIS) across Asian and Caucasian populations. The gene is involved in the growth and development of the spine during childhood. Their study is published today in the journal Nature Genetics. AIS is the most common pediatric skeletal disease, affecting approximately 2% of school-age children. The causes of scoliosis remain largely unknown and brace treatment and surgery are the only treatment options. ...

ANN ARBOR---Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To find out, they turned to experts in computer simulation at the University of Michigan and the Massachusetts Institute of Technology. The result gives nanotechnology researchers a new tool for controlling how objects one-millionth the size of a grain of sand arrange themselves into useful materials---and a means to discover the rest of the tool chest. A ...

PHILADELPHIA—A new study looking at the genomes of more than 13,000 men identified four new genetic variants associated with an increased risk of testicular cancer, the most commonly diagnosed type in young men today. The findings from this first-of-its-kind meta-analysis were reported online May 12 in Nature Genetics by researchers at the Perelman School of Medicine at the University of Pennsylvania. The discovery of these genetic variations—chromosomal "typos," so to speak—could ultimately help researchers better understand which men are at high risk and allow for early ...

Almost two thirds of common plants and half the animals could see a dramatic decline this century due to climate change – according to research from the University of East Anglia. Research published today in the journal Nature Climate Change looked at 50,000 globally widespread and common species and found that two thirds of the plants and half of the animals will lose more than half of their climatic range by 2080 if nothing is done to reduce the amount of global warming and slow it down. This means that geographic ranges of common plants and animals will shrink globally ...

New mutations that are absent in parents but appear in their offspring account for at least 10% of severe congenital heart disease, reveals a massive genomics study led, in part, by researchers at the Yale School of Medicine. The analysis of all the genes of more than 1800 individuals found hundreds of mutations that can cause congenital heart disease, the most common form of birth defect that afflicts nearly 1% of all newborns. In particular, the study found frequent mutations in genes that modify histones, proteins that package DNA in the nucleus and orchestrate the ...

IRAPUATO, MEXICO/BUFFALO, N.Y. — Genes make up about 2 percent of the human genome. The rest consists of a genetic material known as noncoding DNA, and scientists have spent years puzzling over why this material exists in such voluminous quantities. Now, a new study offers an unexpected insight: The large majority of noncoding DNA, which is abundant in many living things, may not actually be needed for complex life, according to research set to appear in the journal Nature. The clues lie in the genome of the carnivorous bladderwort plant, Utricularia gibba. The U. ...

Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments. Researchers found that the size limit for entry is much greater than previously thought, allowing most of a cell's proteins into cilia. The researchers believe that the specific collection of proteins in each cilium, customized to the needs of each cell type, is determined by whether and how cilia keep proteins inside once they enter –– not which ones they allow ...

A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron pump (SEP), described in a paper today in Nature Nanotechnology, provides the speed of electron flow needed to create a new standard for electrical current based on electron charge. The international system of units (SI) comprises seven base units (the metre, kilogram, second, Kelvin, ampere, mole and candela). Ideally these should be stable ...

The gardener's best friend, the earthworm, is great at protecting leaves from being chomped by slugs, suggests research in BioMed Central's open access journal BMC Ecology. Although they lurk in the soil, they seem to protect the plants above ground. Increasing plant diversity also decreases the amount of damage slugs do to individual plants. Spanish slugs (Arion vulgaris) are among the top 100 worst alien species in Europe and are considered a pest almost everywhere. A team of scientists from the University of Natural Resources and Life Sciences Vienna investigated what ...

PHILADELPHIA - Total anomalous pulmonary venous connection (TAPVC), one type of "blue baby" syndrome, is a potentially deadly congenital disorder that occurs when pulmonary veins don't connect normally to the left atrium of the heart. This results in poorly oxygenated blood throughout ...

Every year, thousands of babies are born with severely malformed hearts, disorders known collectively as congenital heart disease. Many of these defects can be repaired though surgery, but researchers don't understand what causes them or how to prevent them. New research shows that about 10 percent of these defects are caused by genetic mutations that are absent in the parents of affected children. Although genetic factors contribute to congenital heart disease, many children born with heart defects have healthy parents and siblings, suggesting that new mutations that ...
