(Press-News.org) The tropical storm that has been hugging the southwestern coast of Mexico moved toward open ocean and strengthened into a hurricane on July 2. NASA's Aqua satellite passed over Dalila after moving away from the coast and strengthening into a hurricane. Dalila has become the third hurricane of the Eastern Pacific Ocean hurricane season after Barbara and Cosme. As Dalila starts to weaken, a new tropical low appears to be developing to the southeast.
On July 2 at 20:55 UTC (4:55 p.m. EDT) flew over Dalila after the storm became a hurricane. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard Aqua took a visible image of Dalila west of the Mexican state of Jalisco. The MODIS image showed strong thunderstorms around the center of circulation and bands of thunderstorms streaming into the center from the northern and southern quadrants. Infrared data from NASA's Atmospheric Infrared Sounder or AIRS instrument that also flies aboard Aqua showed that cloud top temperatures are as cold as -80 Celsius or -112 Fahrenheit.
At 5 a.m. EDT (0900 UTC) on July 3, Dalila had maximum sustained winds near 75 mph (120 kph) making it a Category 1 hurricane. Dalila's center was near latitude 18.1 north and longitude 107.5 west, about 220 miles (350 km) west-southwest of Manzanillo, Mexico. Dalila is moving toward the southwest near 2 mph (4 kph) and the National Hurricane Center expects a slow west-southwestward or southwestward motion over the next day or two, then a turn to the west on July 4, after which time the storm is expected to weaken. The estimated minimum central pressure is 987 millibars.
Although the storm is off the coast of Mexico, coastal areas can expect very rough surf for the next couple of days as the storm continues moving westward. The National Hurricane Center noted that swells generated by Dalila are affecting portions of the southwestern coast of Mexico from near Zihuatanejo to Cabo Corrientes. These swells could cause life-threatening surf and rip current conditions.
Meanwhile, southwest of Dalila, the broad low pressure area called System 97E continues developing several hundred miles south of the Gulf of Tehuantepec. According to NHC, environmental conditions are expected to gradually become more conducive for development over the next couple of days, so System 97E has a medium chance...50 percent...of becoming a tropical cyclone in the next two days as it moves in a westerly direction at about 10 mph.

Forest fires near James Bay, Quebec
2013-07-03
At present the forest fires plaguing the area near James Bay in Quebec are causing air quality problems in the area and as far away as Maine. According to CBC News on July 02, 2013, "A smog warning is in effect for most of southwestern Quebec — from Gatineau to Montreal to Drummondville — and a smog advisory has already been effect for eastern Ontario, which was expanded all the way through Toronto and Hamilton. This current advisory is mostly due to smoke that is blowing into the warning areas from an extensive forest fire near James Bay, which has consumed around 250,000 ...
IRCM scientists find a novel research model for the study of auto-immune diseases
2013-07-03
Montréal, July 3, 2013 – A team of researchers at the IRCM, led by Dr. Javier M. Di Noia in the Immunity and Viral Infections research division, discovered a novel research model for the study of auto-immune diseases. The Montréal scientists are the first to find a way to separate two important mechanisms that improve the quality of antibodies. This study was featured in a recent issue of The Journal of Immunology.
Dr. Di Noia's team studies B cells, a group of white blood cells known as lymphocytes whose main function is to produce antibodies to fight against antigens. ...
Study reports on declines in ecosystem productivity fueled by nitrogen-induced species loss
2013-07-03
(Santa Barbara, Calif.) –– Humans have been affecting their environment since the ancestors of Homo sapiens first walked upright, but never has their impact been more detrimental than in the 21st century. "The loss of biodiversity has much greater and more profound ecosystem impacts than had ever been imagined," said David Tilman, professor of ecology, biodiversity and ecosystem functioning at UC Santa Barbara's Bren School of Environmental Science & Management.
Human-driven environmental disturbances, such as increasing levels of reactive nitrogen and carbon dioxide ...
People's diets show a sugar-fat seesaw
2013-07-03
Research published today shows why people find it hard to follow Government guidelines to cut their fat and sugars intake at the same time - a phenomenon known as the sugar-fat seesaw.
The review, published in the journal Critical Reviews in Food Science and Nutrition, looked at 53 scientific papers and found a strong and consistent inverse association in the percentage of energy coming from fats and sugars. People with diets low in sugars were likely to be high in fat, and vice-versa. Nutritionists have labelled this the 'sugar-fat seesaw'.

Inflammation links social adversity and diabetes
2013-07-03
Diabetes is strongly associated with socioeconomic status (SES): low income, low education, and low occupational status are all linked to a higher risk for diabetes. Trying to understand the mechanisms underlying the association, Silvia Stringhini from the Institute for Social and Preventive Medicine in Lausanne, Switzerland and colleagues report in this week's PLOS Medicine that a substantial part of it appears to be attributable to chronic inflammation.
"Taking together the evidence linking socioeconomic adversity to inflammation and inflammation to type 2 diabetes" ...
Test accurately and swiftly detect most leading causes of bacterial blood stream infection
2013-07-03
A new automated diagnostic test can quickly and accurately identify most leading causes of Gram-positive bacterial blood stream infections and the presence of three antibiotic resistance genes, according to a new study published this week in PLOS Medicine. The findings from the study, conducted by a team of researchers led by Nathan Ledeboer from the Medical College of Wisconsin (MCW), USA, suggest that the new technology could lead to faster diagnosis and treatment of patients suffering from sepsis.
Severe sepsis is a life-threatening condition that is usually triggered ...

2013-07-03
An intervention that consisted of home blood pressure (BP) telemonitoring with pharmacist management resulted in improvements in BP control and decreases in BP during 12 months, compared with usual care, and improvement in BP that was maintained for 6 months following the intervention, according to a study in the July 3 issue of JAMA.
"High blood pressure is the most common chronic condition for which patients visit primary care physicians, affecting about 30 percent of U.S. adults, with estimated annual costs exceeding $50 billion. Decades of research have shown that ...
Study finds in vitro fertilization associated with small increased risk of mental retardation
2013-07-03
In a study that included more than 2.5 million children born in Sweden, compared with spontaneous conception, any in vitro fertilization (IVF) treatment was not associated with autistic disorder but was associated with a small but statistically significantly increased risk of mental retardation, according to a study in the July 3 issue of JAMA. The authors note that the prevalence of these disorders was low, and the increase in absolute risk associated with IVF was small.
"Between 1978 and 2012, approximately 5 million infants worldwide were born from in vitro fertilization," ...
Screening using peptide level and collaborative care to help reduce risk of heart failure
2013-07-03
Among patients at risk of heart failure, collaborative care based on screening for certain levels of brain-type natriuretic peptide reduced the combined rates of left ventricular systolic dysfunction, diastolic dysfunction, and heart failure as well as emergency cardiovascular hospitalizations, according to a study in the July 3 issue of JAMA.
"The increasing prevalence of heart failure [HF] remains a major public health concern underlining the need for an effective prevention strategy. Present-day approaches, focusing mainly on risk factor intervention, have brought ...
Home-based walking exercise program improves speed and endurance for patients with PAD
2013-07-03
In a trial that included nearly 200 participants with peripheral artery disease (PAD), a home-based exercise intervention with a group-mediated cognitive behavioral intervention component improved walking performance and physical activity in patients with PAD, according to a study in the July 3 issue of JAMA.
"Few medical therapies improve the functional impairment associated with lower extremity peripheral artery disease. Supervised treadmill exercise increases maximal treadmill walking distance by 50 percent to 200 percent in individuals with PAD. However, supervised ...
