Visible and infrared satellite data show strong thunderstorms surrounding the low-level center of the tropical storm turned Typhoon Soulik. NASA's Aqua satellite passed over Typhoon Soulik in the Northwestern Pacific Ocean on July 9 and two instruments showed the power in the typhoon's center. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a visible image of Soulik on July 9 at 1:25 UTC (July 8 at 9:25 p.m. EDT). The image shows a tight concentration of thunderstorms around the typhoon's center and ...

In a groundbreaking new study from UC San Francisco, researchers have found that children affected with sensory processing disorders (SPD) have quantifiable differences in brain structure, showing a biological basis for the disease that sets it apart from other neurodevelopmental disorders. SPD—which is more prevalent than autism and as common as attention deficit hyperactivity disorder (ADHD)—receives far less attention than other neurodevelopmental disorders. For one, SPD often occur in children who also have ADHD or autism, and the disorders have never been ...

Hamilton, ON (July 9, 2013) - Three waves of the deadliest influenza pandemic in history, known as the Spanish flu, hit England and Wales in 1918, just as World War 1 was coming to an end. Why flu arrives in multiple waves like this is the focus of a study by McMaster University researchers who discovered three contributing factors: the closing and opening of schools, temperature changes and – most importantly – changes in human behavior. "We found all three factors were important in 1918 but that behavioural responses had the largest effect," said David Earn, an investigator ...

URBANA, Ill. –Tropical climates that allow for year-round farming would seem to be a tremendous economic advantage, but for corn and soybean farmers in the Brazilian state of Mato Grosso it also poses a problem—an abundance of grain followed by about a 10 percent postharvest loss, partially due to a lack of storage. "There is a 34 percent undercapacity of soybean storage, and the situation is aggravated by the rapidly increasing production of second-crop maize," said University of Illinois agricultural economist Peter Goldsmith. "The worst situation occurs in northern ...

The Sun's outer atmosphere, or corona, has posed an enduring mystery. Why is it so hot? The Sun's visible surface is only 10,000 degrees Fahrenheit, but as you move outward the temperature shoots up to millions of degrees. It's like a campfire that feels hotter the farther away you stand. To understand how the corona is heated, some astronomers study coronal loops. These structures are shaped like an upside-down U and show where magnetic field lines are funneling solar gases or plasma. Our best photos of the Sun suggest that these loops are a constant width, like strands ...

People with cheerful temperaments are significantly less likely to suffer a coronary event such as a heart attack or sudden cardiac death, new Johns Hopkins research suggests. Previous research has shown that depressed and anxious people are more likely to have heart attacks and to die from them than those whose dispositions are sunnier. But the Johns Hopkins researchers say their study shows that a general sense of well-being — feeling cheerful, relaxed, energetic and satisfied with life — actually reduces the chances of a heart attack. A report on the research is ...

COLUMBIA, Mo. ¬— CEOs need to demonstrate strong leadership and good decision-making skills, but CEOs with over-confidence can involve their companies in riskier ventures and put investors' funds at risk, according to a new study from the University of Missouri, Georgia Tech University and the University of Texas-Arlington. "Over-confident CEOs feel they have superior decision-making abilities and are more capable than their peers," said Stephen Ferris, professor of finance in the MU Trulaske College of Business. "Unfortunately, they tend to make decisions about mergers ...

Solving the "faint young sun paradox" -- explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today -- may not be as difficult as believed, says a new University of Colorado Boulder study. In fact, two CU-Boulder researchers say all that may have been required to sustain liquid water and primitive life on Earth during the Archean eon 2.8 billion years ago were reasonable atmospheric carbon dioxide amounts believed to be present at the time and perhaps a dash of methane. The key ...

COLUMBIA, Mo. ¬— Some people possess a small number of cells in their bodies that are not genetically their own; this condition is known as microchimerism. It is difficult to determine potential health effects from this condition because of humans' relatively long life-spans. Now, researchers at the University of Missouri have found that microchimerism can be found in dogs as well. Jeffrey Bryan, an associate professor of oncology at the MU College of Veterinary Medicine and director of Comparative Oncology and Epigenetics Laboratory, says this discovery will help doctors ...

Low vitamin D blood levels are linked to greater risk of heart disease in whites and Chinese, but not in blacks and Hispanics, according to a study appearing this week in JAMA, a journal published by the American Medical Association. Growing evidence has suggested that low blood levels of 25-hydroxyvitamin are associated with higher risk of developing coronary heart disease among whites. Few of these studies included substantial numbers of people from other races. Vitamin D levels tend to be lower among people from other racial and ethnic minority groups, and some of ...

Using a new analytical methodology--a coupled micro-computed X-ray tomography (MicroCT) and microfluidic-based electrochemical analysis--researchers at the University of Illinois at Urbana-Champaign are gaining new insights into electrode structure-performance relationships for energy conversion and storage devices. "Electrodes play a vital role in all devices based on heterogeneous electrochemical reactions for energy conversion, energy storage, and chemical synthesis," explained Molly Jhong, a graduate student at the Department of Chemical and Biomolecular Engineering ...

Rockville, Md. — Vision researchers have developed new software that will analyze visual fields in an open-source platform to improve and encourage collaborative research among independent labs. An analysis of the free tool is presented in a Journal of Vision (JOV) paper, The visualFields package: A tool for analysis and visualization of visual fields. In the paper, authors introduce and demonstrate the visualFields package, which can work separately or in conjunction with the Open Perimetry Interface — an open-source software developed by Andrew Turpin, PhD, and described ...

ARLINGTON HEIGHTS, ILL. -- The allergist's office might not be a child's favorite place to visit, but it is a place where they should be able to say how their asthma makes them feel. While children might rely on parents to tell their doctor about how they are feeling, according to a study released today, children should do most of the talking. The study, published in the July issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), found that children with asthma report having a better quality ...

This news release is available in German. The economic crisis has put measurable pressure on birthrates in Europe over the last decade. On average, the more the unemployment rose, the greater the decrease in fertility compared to the number of children per women expected without the crisis. This is the result of a new study performed by the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany. MPIDR demographers Michaela Kreyenfeld, Joshua Goldstein and Aiva Jasilioniene have just published their analysis together with Deniz Karaman Örsal of the ...

LA JOLLA, CA - Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, published on July 3 in Cell, a team of scientists at the Salk Institute for Biological Studies finds that disrupted micronuclei, which can trigger massive DNA damage on chromosomes, might play an even more active role in carcinogenesis ...

Relationship problems can keep us awake at night. But new research from UC Berkeley suggests that sleepless nights also can worsen lovers' fights. UC Berkeley psychologists Amie Gordon and Serena Chen have found that people are much more likely to lash out at their romantic partners over relationship tensions after a bad night's sleep. "Couples who fight more are less happy and less healthy," said Gordon, a doctoral student in psychology and lead author of the study published online in the journal, Social Psychological and Personality Science. "Our research helps ...

Global atmospheric change, stagnation of yield increases, uncertain societal acceptance, and government policies are some of the greatest barriers to meeting the growing demand for food, feed and fuel from our major crops, said guest lecturer Stephen Long at the 2013 American Association for the Advancement of Science (AAAS) and World Food Prize Foundation (WFPF) Charles Valentine Riley Memorial Lecture on June 25 in Washington, D.C. Biotechnology and new sustainable bioenergy crops will be imperative to overcome these challenges, said Long, a Gutgesell Endowed Professor ...

(SACRAMENTO, Calif.) -- The U.S. News & World Report graduate school rankings inspire discussion and marketing, but do they actually reflect quality differences between schools when it comes to medical education in primary care? Researchers at the UC Davis School of Medicine are believed to be the first to take on that question by analyzing the primary care rankings from 2009 through 2012, reconstructing scores and proposing alternative measurements. Their findings are published online now, ahead of the August 13 print issue of the journal Academic Medicine. Printed ...

University of Adelaide researchers have developed a new nanomaterial that could help reduce carbon dioxide emissions from coal-fired power stations. The new nanomaterial, described in the Journal of the American Chemical Society, efficiently separates the greenhouse gas carbon dioxide from nitrogen, the other significant component of the waste gas released by coal-fired power stations. This would allow the carbon dioxide to be separated before being stored, rather than released to the atmosphere. "A considerable amount of Australia's – and the world's – carbon dioxide ...

UC Davis MIND Institute researchers have identified the specific antibodies that target fetal brain proteins in the blood of a subset of women whose children are diagnosed with autism. The finding is the first to pinpoint a specific risk factor for a significant subset of autism cases, as well as a biomarker for drug development and early diagnosis. The researchers have named autism related to these antibodies "Maternal Autoantibody-Related," or MAR autism. The study found that the mothers of children with autism were more than 21 times as likely to have the specific ...

Researchers with the UC Davis MIND Institute have found that prenatal exposure to specific combinations of antibodies found only in mothers of children with autism leads to changes in the brain that adversely affect behavior and development. The researchers said that the highly specific immunoglobulin-G (IgG) autoantibodies cross the placenta during pregnancy to impact fetal brain development, resulting in a form of autism that the researchers now are calling maternal antibody-related (MAR) autism. The researchers said that MAR autism cases could represent as much as ...

Each year in the United States, cats deposit about 1.2 million metric tons of feces into the environment, and that poop is carrying with it what may be a vast and underappreciated public health problem, say scientists July 9 in the journal Trends in Parasitology, a Cell Press publication. Some of that poop is laden with an infectious parasite known as Toxoplasma gondii, a protozoan that has recently caused toxoplasmosis epidemics in otherwise healthy people, not just in pregnant women or people with immune deficiencies. Additional concerns have been raised by studies ...

ANN ARBOR –While record numbers of hospitals and doctors participate in electronic health information exchange efforts, which enable medical histories to follow patients as they move between healthcare providers, the long-term success of these programs is in question. That's according to a new national survey of health information exchange organizations led by a University of Michigan researcher. Health information exchange efforts come into play primarily when patients switch doctors or are admitted to a hospital. Because they give doctors access to patients' medical ...

London -- Women who give birth to multiple babies following IVF treatment are at a higher risk of breast cancer than those giving birth to singletons or who remain childless. Dutch investigators from the Omega study group said the explanation may not be the multiple pregnancy per se but a maternal trait related to a higher implantation potential and to breast cancer itself. Although the results were derived from a large nationwide cohort study, the investigators emphasise that the findings should next be replicated in further studies and that presently there is no reason ...

London, 9 July 2013: An analysis of almost 10,000 first cycles of egg donation treatment at one of Europe's largest IVF centres shows that female obesity reduces the receptivity of the uterus to embryo implantation and thereby compromises reproductive outcome. The investigators report that excess female weight "impairs human reproduction" and that "the reduction of uterine receptivity is one of the mechanisms involved". As a result they advise weight reduction before pregnancy in any type of conception, including ovum donation. The study is presented today at the ...
