Tropical Storm Erika was centered in the Eastern Caribbean Sea and affecting Puerto Rico and Hispaniola when NASA's Terra satellite passed overhead mid-day on Friday, August 28, 2015. Two hours after Terra passed, NOAA's GOES-East satellite saw Erika's western side over the Dominican Republic. At 15:05 UTC (11:05 a.m. EDT) the Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite captured a visible light image Tropical Storm Erika approaching Hispaniola. Erika's center was in the eastern Caribbean Sea, and the northern quadrant of the ...

To understand how confidence in parenting may predict parenting behaviors in women who were abused as children, psychologists at the University of Rochester have found that mothers who experienced more types of maltreatment as children are more critical of their ability to parent successfully. Intervention programs for moms at-risk, therefore, should focus on bolstering mothers' self-confidence--not just teach parenting skills, the researchers said. "We know that maltreated children can have really low self-esteem," said Louisa Michl, a doctoral student in the department ...

A simple change in the wording of a traffic sign - from "Share the Road" to "Bicycles May Use Full Lane" - could help clarify the rules of the road for bicyclists and motorists, according to a North Carolina State University study. "'Share the Road' signs are common but what that means in terms of how drivers and bicycle riders should interact can be ambiguous," says George Hess, natural resources professor and co-author of the study in PLOS One. Some bicyclists complain that motorists consider them to be in the way, while some motorists accuse bicyclists of hogging ...

Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physics--the laws and principles that appear to explain the physics of relatively large objects at human scale. However, quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale, state that nothing can quite be completely at rest. For the first time, a team of Caltech researchers and collaborators has ...

Washington DC - August 28, 2015 - Oysters not only transmit human norovirus; they also serve as a major reservoir for these pathogens, according to research published August 28 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. "More than 80 percent of human norovirus genotypes were detected in oyster samples or oyster-related outbreaks," said corresponding author Yongjie Wang, PhD. "The results highlight oysters' important role in the persistence of norovirus in the environment, and its transmission to humans, and they demonstrate ...

NASA-NOAA's Suomi NPP satellite flew over Hurricane Jimena in the Eastern Pacific and saw the strongest thunderstorms building up quickly, especially in the northern quadrant of the storm. Jimena intensified rapidly overnight on August 27 and early August 28 and the National Hurricane Center expects it to become a major hurricane. The Visible Infrared Imaging Radiometer Suite or VIIRS instrument aboard the satellite provided infrared data of the storm that showed the coldest cloud top temperatures, which indicate the strongest thunderstorms were in Jimena's northern ...

Generating and storing renewable energy, such as solar or wind power, is a key barrier to a clean-energy economy. When the Joint Center for Artificial Photosynthesis (JCAP) was established at Caltech and its partnering institutions in 2010, the U.S. Department of Energy (DOE) Energy Innovation Hub had one main goal: a cost-effective method of producing fuels using only sunlight, water, and carbon dioxide, mimicking the natural process of photosynthesis in plants and storing energy in the form of chemical fuels for use on demand. Over the past five years, researchers at ...

If you think that performing CPR on a person whose heart has stopped is a surefire way to save their life, you may be watching too much TV. The truth is more depressing than fiction, according to a new study by University of Southern California Davis School of Gerontology researchers. While medical dramas Grey's Anatomy and House show cardiopulmonary resuscitation saving a patient's life nearly 70 percent of the time, the real immediate survival rate is nearly half that - around 37 percent. Researchers also found another discrepancy between reality and TV: Half of ...

TAMPA, Fla. - Pancreatic cancer is the fourth most common cause of cancer-related death in the United States and has a 5-year survival rate of only 6 percent, which is the lowest rate of all types of cancer according to the American Cancer Society. This low survival rate is partially attributed to the difficulty in detecting pancreatic cancer at an early stage. According to a new 'proof of principle' study published in Aug. 27 issue of Cancer Prevention Research, Moffitt Cancer Center researchers hope to improve pancreatic cancer survival rates by identifying markers in ...

Beach sand contains all kinds of microorganisms, including those that can harm human health. Yet current guidelines are focused exclusively on monitoring the levels of microbes in the water. Now, an international panel of scientists is recommending monitoring the sand at recreational beaches, to minimize health risks for beachgoers. Their advice is based on the general consensus reached during the international conference "Trends in Environmental Microbiology and Public Health," held in Lisbon Portugal in September 2014. "Beach sands accumulate contaminants and people ...

A collaboration between biologists and engineers at Monash University has led to the development of a new non-invasive image processing technique to visualise embryo formation. Researchers were able to see, for the first time, the movement of all of the cells in living mammalian embryos as they develop under the microscope. This breakthrough has important implications for IVF (in vitro fertilisation) treatments and pre-implantation genetic diagnosis (PGD). In the future, this approach could help with embryo selection before the embryo is implanted back into the uterus to ...

A German-French team has developed a light-sensitive switch that regulates a protein implicated in the neurobiology of synaptic plasticity. The agent promises to shed new light on the phenomenology of learning, memory and neurodegeneration. Learning is made possible by the fact that the functional connections between nerve cells in the brain are subject to constant remodeling. As a result of activation-dependent modification of these links ('synaptic plasticity'), circuits that are repeatedly stimulated "learn" to transmit signals ever more efficiently. This process is ...

This news release is available in German. A new international study shows that 5,000 foetuses in Europe annually are affected by spina bifida and other severe defects on the central nervous system. Seventy per cent of these pregnancies are terminated, while increased mortality and serious diseases affect the children who are born. At least half of the cases can be avoided by adding folic acid to staple foods as is already being done in seventy non-European countries. A lack of folic acid enrichment in Europe is the cause of several thousand cases of foaetal abnormalities ...

Parents go to great lengths to ensure the health and well-being of their developing offspring. The favor, however, may not always be returned. Dramatic research has shown that during pregnancy, cells of the fetus often migrate through the placenta, taking up residence in many areas of the mother's body, where their influence may benefit or undermine maternal health. The presence of fetal cells in maternal tissue is known as fetal microchimerism. The term alludes to the chimeras of ancient Greek myth--composite creatures built from different animal parts, like the goat-lion-serpent ...

When a plant dies, its leaves and branches fall to the ground. Decomposition of soil organic matter is then mainly carried out by fungi and bacteria, which convert dead plant materials into carbon dioxide and mineral nutrients. Until now, scientists have thought that high quality organic materials, such as leaves that are rich in soluble sugars, are mainly decomposed by bacteria. Lower quality materials, such as cellulose and lignin that are found in wood, are mainly broken down by fungi. Previous research has also shown that organic material that is broken down by ...

The scientific team of a new biotech company Gero in collaboration with one of the leading academics in the field of aging Prof. Robert J. Shmookler Reis (current world record holder in life extension for model animals - 10 fold for nematodes) has recently brought new insights into biology of aging and age-related diseases, primarily, around the stability and stress resistance of certain gene regulatory networks. The work has just been published as "Stability analysis of a model gene network links aging, stress resistance, and negligible senescence" in Scientific Reports ...

A new method of manufacturing glass could lead to the production of 'designer glasses' with applications in advanced photonics, whilst also facilitating industrial scale carbon capture and storage. An international team of researchers, writing today in the journal Nature Communications, report how they have managed to use a relatively new family of sponge-like porous materials to develop new hybrid glasses. The work revolves around a family of compounds called metal-organic frameworks (MOFs), which are cage-like structures consisting of metal ions, linked by organic bonds. ...

MANHASSET, NY - Investigators at The Feinstein Institute for Medical Research have discovered that brain scans can be used to predict patients' response to antipsychotic drug treatment. The findings are published online in the latest issue of The American Journal of Psychiatry. Psychotic disorders, such as schizophrenia and bipolar disorder, are characterized by delusions, hallucinations, and disorganized thoughts and behavior. They are estimated to occur in up to three percent of the population and are a leading cause for disability worldwide. Psychotic episodes are ...

Young people who identify with the goth subculture might be at increased risk of depression and self-harm, according to new research published in The Lancet Psychiatry journal. The findings show that teenagers who identified very strongly with being a goth at age 15 were three times more likely to be clinically depressed and were five times more likely to self-harm at age 18 than young people who did not identify with the goth subculture. "Our study does not show that being a goth causes depression or self-harm, but rather that some young goths are more vulnerable to ...

Highlights Compared with their sister(s) who had normal blood pressure during pregnancy, women who had hypertension in pregnancy were more likely to develop hypertension later in life. Brothers and sisters of women who had high blood pressure during pregnancy were at increased risk of developing high blood pressure later in life. Brothers, but not sisters, of women who had high blood pressure in pregnancy were also at increased risk of developing heart disease. Hypertension develops in approximately 8% of pregnancies. Washington, DC (August 27, 2015) ...

Licensed tobacco retailers throughout New York City are selling a substantial number of cigarette packs carrying either counterfeit or out-of-state tax stamps, finds an investigation by NYU public health researchers. These illegal cigarette sales are more pervasive in independent stores, as opposed to chain stores, according to the study published in the BMJ journal Tobacco Control. "Our research found that illegal cigarettes are regularly available over the counter in New York City," said study author Diana Silver, associate professor of public health at NYU's Steinhardt ...

EL PASO, Texas - A University of Texas at El Paso (UTEP) study on children's health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs. UTEP researchers analyzed academic performance and sociodemographic data for 1,895 fourth and fifth grade children living in El Paso, Texas that were attending the El Paso Independent School District (EPISD). They used the Environmental Protection Agency's National Air Toxics Assessment to estimate children's exposure to toxic air pollutants, such as diesel exhaust, ...

TALLAHASSEE, Fla. --A Florida State University engineering professor has developed a new highly efficient and low cost light emitting diode that could help spur more widespread adoption of the technology. "It can potentially revolutionize lighting technology," said Assistant Professor of Industrial and Manufacturing Engineering Zhibin Yu. "In general, the cost of LED lighting has been a big concern thus far. Energy savings have not balanced out high costs. This could change that." Yu developed this new LED technology using a combination of organic and inorganic materials. ...

Not just anything is allowed to enter the nucleus, the heart of eukaryotic cells where, among other things, genetic information is stored. A double membrane, called the nuclear envelope, serves as a wall, protecting the contents of the nucleus. Any molecules trying to enter or exit the nucleus must do so via a cellular gatekeeper known as the nuclear pore complex (NPC), or pore, that exists within the envelope. How can the NPC be such an effective gatekeeper--preventing much from entering the nucleus while helping to shuttle certain molecules across the nuclear envelope? ...

The Global Precipitation Measurement or GPM core satellite has provided meteorologists with a look at the towering thunderstorms and heavy rainfall occurring in Tropical Storm Erika as it moves through the Caribbean Sea. On August 27, 2015, there were many warnings and watches in effect as Tropical Storm Erika continued to rain on Leeward Islands. A Tropical Storm Warning was in effect for Anguilla, Saba and St. Eustatius, St. Maarten, St. Martin, St. Barthelemy, Montserrat, Antigua and Barbuda, St. Kitts and Nevis, Puerto Rico, Vieques, Culebra, U.S. Virgin Islands, ...
