The green of St. Patrick's Day in the Mid-Atlantic was covered by white snow as a result of a late winter snow storm. The covering of the green was captured in a movie made at NASA using NOAA's GOES satellite data. The winter storm dropped snow totals from 6" to 12" of snow from Baltimore, Md. to Richmond, Va. The storm arrived during the evening of March 16 and continued through March 17. As of 1 p.m. EDT, light bands of snow continued to fall throughout the Washington, D.C. area. NOAA's GOES-East satellite captured the path the storm took through the Mid-Atlantic ...

Adult survivors of childhood cancer face significant health problems as they age and are five times more likely than their siblings to develop new cancers, heart and other serious health conditions beyond the age of 35, according to the latest findings from the world's largest study of childhood cancer survivors. St. Jude Children's Research Hospital led the research, results of which appear in the March 17 issue of the Journal of Clinical Oncology. The federally funded Childhood Cancer Survivor Study (CCSS) found that the health gap between survivors and their siblings ...

Of thousands of known species of Drosophila fruit flies, just one is known as a crop pest, depositing eggs inside ripening fruit so its maggots can feed and grow. New research from the University of California, Davis, shows the similarities and crucial differences between this pest and its close relatives — and that one related fly has potential to also become a pest. Drosophila flies, found worldwide, lay their eggs in rotting fruit. Drosophila suzukii, also referred to as "spotted-wing Drosophila" because the male has large black blotches on his wings (as do males of ...

The success of having software programmers work in pairs greatly depends on the ability level of those individual programmers, two UT Arlington College of Business professors have written in a recently released paper. The paper also concluded that using design patterns can greatly improve the quality of software programs and the productivity of programmers. Professor Radha Mahapatra and Associate Professor Sridhar Nerur, both in the Information Systems and Operations Management Department of the College of Business, recently published "Distributed Cognition in Software ...

Certain micro-organisms can constitute the active matter to develop bioinsecticides used for pest control. In this case, the researcher used a virus of the baculovirus family, which specifically infect invertebrates and naturally regulate the population of insects of this type on the ground. "We selected a virus that displayed the best insecticidal characteristics," she explained. "Using this virus we developed a large-scale production system by means of which we could treat a surface area equivalent to that of a football pitch using just two larvae." When a larva infected ...

Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers at Umeå University in Sweden have discovered that controlled placement of the carbon nanotubes into nano-structures produces a huge boost in electronic performance. Their groundbreaking results are published in the prestigious journal Advanced Materials. Carbon nanotubes, CNTs, are one dimensional nanoscale cylinders made of carbon atoms that possess very unique properties. For example, they have very high tensile strength and exceptional electron ...

DALLAS – March 18, 2014 – UT Southwestern Medical Center cardiologists have defined a novel heart failure symptom in advanced heart failure patients: shortness of breath while bending over, such as when putting on shoes. The condition, which UT Southwestern cardiologists named "bendopnea" (pronounced "bend-op-nee-ah"), is an easily detectable symptom that can help doctors diagnose excessive fluid retention in patients with heart failure, according to the findings published in a recent edition of the Journal of the American College of Cardiology: Heart Failure. "Some ...

This news release is available in German. The hunt is on – for new materials to be used in the next generation of batteries that may one day replace current lithium ion batteries. Today, the latter are commonplace and provide a reliable power source for smartphones, laptops and many other portable electrical devices. On the one hand, however, electric mobility and stationary electricity storage demand a greater number of more powerful batteries; and the high demand for lithium may eventually lead to a shortage of the raw material. This is why conceptually identical ...

BLOOMINGTON, Ind. -- Scientists from Indiana University are part of a consortium that has described the transcriptome of the fruit fly Drosophila melanogaster in unprecedented detail, identifying thousands of new genes, transcripts and proteins. In the new work, published Sunday in the journal Nature, scientists studied the transcriptome -- the complete collection of RNAs produced by a genome -- at different stages of development, in diverse tissues, in cells growing in culture, and in flies stressed by environmental contaminants. To do so, they used contemporary sequencing ...

An ultrasound of the lungs could help doctors quickly determine if a pregnant woman with preeclampsia is at risk for respiratory failure, suggests preliminary research published in the April issue of Anesthesiology. About 60,000 women worldwide die as a result of preeclampsia, which causes severely high blood pressure. Potential complications include stroke, bleeding and excess fluid in the lungs – called pulmonary edema – which can lead to respiratory failure. The study suggests a lung ultrasound can help doctors easily learn whether a woman with preeclampsia is suffering ...

Although cardiac arrest during childbirth is rare, it may be two times more common than previously reported in the literature, suggests the first large U.S. study on the potentially deadly condition published in the April issue of Anesthesiology. The study, based on data for more than 56 million births, also found that cardiopulmonary resuscitation (CPR) was often successful, and that the survival rate improved between 1998 and 2011. Maternal cardiac arrest means that the mother's heart stops beating, either before or after childbirth. More than one in 12,000 American ...

Germany, Austria and Cuba have at least one thing in common: they have all experienced what it means to be 'left out in the cold' and be considered 'bad company' by Western powers. However, just as Iran and South Africa, these three countries have handled this form of stigmatization very differently. According to new research, the reason for this is that diplomatic pressure and sanctions by the international community (the 'shaming method' ) fail to have the intended effect because isolation and shaming may boost national pride and sense of cohesion and thus support the ...

More than 40 percent of pregnant low-income women discharged from the hospital after a diagnosis of false or early labor did not want to be sent home, with the most common reasons being that they were in too much pain or lived too far away, according to a study by Baylor University's Louise Herrington School of Nursing (LHSON) and Parkland Health & Hospital System. Many of the women dissatisfied with being sent home stated that receiving specific written instructions about when to return to the hospital may have made them happier about going home. However, there was evidence ...

Agricultural fires continue to burn in the Indochina region as evidenced by this Aqua image taken on March 18, 2014. This natural-color image was taken by the Moderate Resolution Imaging Spectroradiometer, MODIS, aboard the Aqua satellite. More fires have been set in both Burma and Laos since the last image taken by MODIS on March 07. Actively burning areas, detected by MODIS's thermal bands, are outlined in red. Fire is used in cropland areas for pest and weed control and to prepare fields for planting. Crop residue burning helps farmers as it is a cheap and effective ...

A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining light-emitting diodes (LEDs) with a superconductor to generate entangled photons and could open up a rich spectrum of new physics as well as devices for quantum technologies, including quantum computers and quantum communication. Entanglement occurs when particles become correlated in pairs to predictably interact with each other regardless of how far apart they ...

NASA's TRMM satellite passed over the remnants of Tropical Cyclone Gillian and spotted some towering thunderstorms and areas of heavy rainfall, indicating there's still power in the former tropical storm. Over the past few days former tropical cyclone Gillian's remnants moved from the Gulf of Carpentaria into the Timor Sea. The Tropical Rainfall Measuring Mission satellite known as TRMM found a few strong convective thunderstorms when it passed above these remnants on March 18, 2014 at 0431 UTC. TRMM's Precipitation Radar (PR) instrument measured rain falling at a rate ...

URBANA, Ill. – Even after the agricultural reforms of 2002-03, for wheat, rice, and pearl millet farmers in India, grain markets are still pretty sticky. Two University of Illinois economists analyzed infrastructure of interstate trade for food-grain crops in three Indian states and found that grain farmers are unable to cash in on India's market reforms and take advantage of a price difference between two or more markets. "We wanted to see if there was more integration in the markets since the 2002 reforms," said Kathy Baylis. "We were surprised at how little integration ...

Technology used in video games is making its way to hospital rooms, where researchers at the University of Missouri hope to learn new ways to prevent falls among hospital patients. Between 700,000 and 1 million people each year fall in U.S. hospitals, according to the Agency for Healthcare Research and Quality. Hospitals nationwide are looking for ways to reduce that number. "Since 2008, we've investigated ways to detect and prevent falls by older adults living in independent senior apartments," said Marilyn Rantz, PhD, RN, a leader of the MU research team and a professor ...

A critically endangered plant known as marsh sandwort (Arenaria paludicola) is inching back from the brink of extinction thanks to the efforts of a UC Santa Cruz plant ecologist and her team of undergraduate students. Ingrid Parker, the Langenheim professor of plant ecology and evolution at UC Santa Cruz, got involved in the marsh sandwort recovery effort at the request of the U.S. Fish and Wildlife Service (USFWS). Although it used to occur all along the west coast, from San Diego to Washington state, this wetland plant with delicate white flowers had dwindled to one ...

A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimer's disease (AD). Moreover, the candidate inhibitor drug has been shown to be safe in humans. The findings, based on AD mouse models and published online in the Journal of Alzheimer's Disease, support continued development of cysteine ...

People who experience chronic sleep disturbance—either through their work, insomnia or other reasons—could face an earlier onset of dementia and Alzheimer's, according to a new pre-clinical study by researchers at Temple University. "The big biological question that we tried to address in this study is whether sleep disturbance is a risk factor to develop Alzheimer's or is it something that manifests with the disease," said Domenico Praticò, professor of pharmacology and microbiology/immunology in Temple's School of Medicine, who led the study. Initially, the researchers ...

AURORA, Colo. (March 17, 2014) - Helping children learn to eat well can be a challenge. Some children happily eat whatever is put in front of them while others seem to eat like birds and exist more on air than food. A new study by a researcher at the University of Colorado School of Medicine shows that parents influence how much children eat more than they may think. In this collaborative study between the CU School of Medicine, Baylor College of Medicine and University of Alabama Birmingham, researchers observed normal, everyday mealtimes in the homes of 145 parents ...

DALLAS, March 18, 2014 — As some countries and companies roll out new rules to limit animal testing in pharmaceutical products designed for people, scientists are stepping in with a new way to test therapeutic drug candidates and determine drug safety and drug interactions — without using animals. The development of "chemosynthetic livers," which could dramatically alter how drugs are made, was presented at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. The meeting features more than 10,000 presentations ...

STANFORD, Calif. — California sea lions exposed to a toxin in algae develop a form of epilepsy that is similar to one in humans, according to a new study led by Stanford University School of Medicine researchers. Every year, hundreds of sea lions wash up along the California coast, suffering seizures caused by exposure to domoic acid, a neurotoxin that can produce memory loss, tremors, convulsions and death. Domoic acid is produced by algae blooms that have been proliferating along the coast in recent years, accumulating in anchovies and other small fish that the sea ...

WASHINGTON D.C., March 18, 2014 -- A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible. The model is the first to represent the start of a supernova collapse in three dimensions, said its developer, W. David Arnett, Regents Professor of Astrophysics at the University of Arizona, who developed the model with Casey Meakin and Nathan Smith at Arizona and Maxime Viallet of the Max-Planck Institut ...
