(Press-News.org) Hurricane Emilia reached peak intensity yesterday, July 10, when its maximum sustained winds hit 140 mph (220 kmh). Today, July 11, Emilia has weakened to a Category 2 hurricane. NASA's Aqua satellite passed over Emilia during its weakening phase.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite captured a visible image of Hurricane Emilia on July 10, 2012 at 2035 UTC / 4:35 p.m. EDT when its winds had weakened down to 125 mph (205 kmh). Emilia continued weakening after Aqua passed by.
On July 11 at 5 a.m. EDT, Emilia's maximum sustained winds were near 105 mph (165 kmh) and is now a Category 2 hurricane on the Saffir-Simpson scale. Emilia is over 210 miles (330 km) in diameter, which is the extent of its tropical-storm-force winds. On July 11 the Atmospheric Infrared Sounder (AIRS) data from NASA's Aqua satellite showed that cloud top temperatures around Emilia's eye were still as cold as -94 Fahrenheit (-70 Celsius) indicating the eye is still surrounded by powerful thunderstorms.
Emilia was located about 720 miles (1160 km) southwest of the southern tip of Baja California. Emilia is moving at 10 mph (17 kmh) to the west-northwest. Emilia is expected to continue moving in the same direction because it is skirting the southern edge of a subtropical ridge (elongated area) of high pressure (which rotates clockwise), located to its north.
The National Hurricane Center expects Emilia to continue on a weakening trend as it moves over cooler waters and runs into drier and more stable air as wind shear increases.

Want to get teens interested in math and science? Target their parents
2012-07-12
Increasing the number of students interested in science, technology, engineering, and math – otherwise known as the STEM disciplines – is considered to be vital to national competitiveness in the global economy and to the development of a strong 21st century workforce. But the pipeline leading toward STEM careers begins leaking in high school, when students choose not to take advanced courses in science and math.
Experts in research and policy have examined different ways to enhance and promote STEM education, but most of these efforts are focused within the four walls ...
Cleveland Clinic researchers discover molecule that may prevent atherosclerosis
2012-07-12
Wednesday, July 11, 2012, Cleveland: Cleveland Clinic researchers have discovered that a naturally occurring molecule may play a role in preventing plaque buildup inside arteries, possibly leading to new plaque-fighting drugs and improved screening of patients at risk of developing atherosclerosis.
Sometimes called hardening or clogging of the arteries, atherosclerosis is the buildup of cholesterol, fatty cells, and inflammatory deposits on the inner walls of the arteries, restricting blood flow to the heart. The disease can affect the arteries in the heart, legs, brain, ...

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially ...
Using biomarkers to identify and treat schizophrenia
2012-07-12
In the current online issue of PLoS ONE, researchers at the University of California, San Diego School of Medicine say they have identified a set of laboratory-based biomarkers that can be useful for understanding brain-based abnormalities in schizophrenia. The measurements, known as endophenotypes, could ultimately be a boon to clinicians who sometimes struggle to recognize and treat the complex and confounding mental disorder.
"A major problem in psychiatry is that there are currently no laboratory tests that aid in diagnosis, guide treatment decisions or help predict ...
The emotion detectives uncover new ways to fight off youth anxiety and depression
2012-07-12
CORAL GABLES, FL (July 11, 2012)—Emotional problems in childhood are common. Approximately 8 to 22 percent of children suffer from anxiety, often combined with other conditions such as depression. However, most existing therapies are not designed to treat co-existing psychological problems and are therefore not very successful in helping children with complex emotional issues.
To develop a more effective treatment for co-occurring youth anxiety and depression, University of Miami (UM) psychologist Jill Ehrenreich-May and her collaborator Emily L. Bilek analyzed the efficacy ...
Transforming cancer treatment
2012-07-12
A Harvard researcher studying the evolution of drug resistance in cancer is predicting that, in a few decades, "many, many cancers could be manageable."
Martin Nowak, a Harvard Professor of Mathematics and of Biology and Director of the Program for Evolutionary Dynamics, is one of several co-authors of a paper, published in Nature, that details how resistance to targeted drug therapy emerges in colorectal cancers, and suggests a new, multi-drug approach to treatment could make many cancers manageable, if not curable, illnesses.
The key, Nowak's research suggests, ...
Cells derived from debrided burn tissue may be useful for tissue engineering
2012-07-12
Putnam Valley, NY. (July 11, 2012) –A research team in the Netherlands has found that cells from burn eschar, the non-viable tissue remaining after burn injury and normally removed to prevent infection, can be a source of mesenchymal cells that may be used for tissue engineering. Their study compared the efficacy of those cells to adipose (fat)-derived stem cells and dermal fibroblasts in conforming to multipotent mesenchymal stromal cell (MSC) criteria.

Toward new drugs for the human and non-human cells in people
2012-07-12
Amid the growing recognition that only a small fraction of the cells and genes in a typical human being are human, scientists are suggesting a revolutionary approach to developing new medicines and treatments to target both the human and non-human components of people. That's the topic of an article, which reviews work relating to this topic from almost 100 studies, in ACS' Journal of Proteome Research.
Liping Zhao, Jeremy K. Nicholson and colleagues explain that human beings have been called "superorganisms" because their bodies contain 10 percent human cells and 90 ...
Widespread exposure to BPA substitute is occurring from cash register receipts, other paper
2012-07-12
People are being exposed to higher levels of the substitute for BPA in cash register thermal paper receipts and many of the other products that engendered concerns about the health effects of bisphenol A, according to a new study. Believed to be the first analysis of occurrence of bisphenol S (BPS) in thermal and recycled paper and paper currency, the report appears in ACS' journal Environmental Science & Technology.
Kurunthachalam Kannan and colleagues point out that growing evidence of the potentially toxic effects of BPA has led some manufacturers to replace it with ...
