Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all three factors to reveal the dynamics at play in a process called sympatric speciation. Titled "Factors influencing progress toward sympatric speciation," the paper appears in today's edition of the Journal of Evolutionary Biology. New species more commonly occur when plants or animals cannot interbreed because of strong mate choice, and therefore they become isolated genetically. ...

(CHICAGO) – An innovative approach for implanting a new aortic heart valve without open-heart surgery is being offered at Rush University Medical Center to patients with severe aortic stenosis who are at high-risk or not suitable candidates for open heart valve replacement surgery. "This breakthrough technology could save the lives of thousands of patients with heart valve disease who have no other therapeutic options," says Dr. Ziyad Hijazi, director of the Rush Center for Congenital and Structural Heart Disease and interventional cardiologist of the Rush Valve Clinic. ...

(PHILADELPHIA) -- More than 200,000 people are treated for cardiac arrest in United States hospitals each year, a rate that may be on the rise. The findings are reported online this week in Critical Care Medicine in a University of Pennsylvania Perelman School of Medicine-led study. Though cardiac arrest is known to be a chief contributor to in-hospital deaths, no uniform reporting requirements exist across the nation, leaving experts previously unable to calculate its true incidence and study trends in cardiac arrest mortality and best practices in resuscitation care. ...

New Rochelle, NY, June 24, 2011—David Satcher, MD, PhD, former U.S. Surgeon General, describes childhood obesity as "one of the greatest threats to child and adult health that we are facing today," calling for an intensive effort to promote child health, in an editorial in the June issue of Childhood Obesity, a peer-reviewed journal published by Mary Ann Liebert, Inc. The editorial is available online. A long-time advocate in the fight against obesity, Dr. Satcher released the first Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity during ...

KCRG TV reported that Iowa hospitals do not have to publically report medical errors. The question is how this influences patient safety in Iowa. The hospitals claim that merely requiring reporting of medical errors to the state does not ensure that the errors will be corrected. Scott McIntyre, spokesman for the Iowa Hospital Association, said to KCRG TV that, "Government regulation does not create that kind of buy-in or progress," and that "it can stifle innovation as providers focus on meeting the mandate and little more." Minnesota's Experience In ...

CORVALLIS, Ore. – About 100 million years ago, a tiny mayfly had a problem. Like most adult mayflies, she only had that one day to live anyway, so there was no time to waste. She took her mating flight, got fertilized, and was about to lay her eggs when something went horribly wrong. She got stuck in some oozing tree sap and died, preserved for all time in the magic of amber. There would be ho hatchlings. It was a pretty rude ending to what was already going to be a short adulthood. But her personal tragedy proved fortunate for scientists. The tiny specimen – just described ...

The coconut (the fruit of the palm Cocos nucifera) is the Swiss Army knife of the plant kingdom; in one neat package it provides a high-calorie food, potable water, fiber that can be spun into rope, and a hard shell that can be turned into charcoal. What's more, until it is needed for some other purpose it serves as a handy flotation device. No wonder people from ancient Austronesians to Captain Bligh pitched a few coconuts aboard before setting sail. (The mutiny of the Bounty is supposed to have been triggered by Bligh's harsh punishment of the theft of coconuts from ...

Much has been written in recent years about the positive impact apologies may have in civil litigation, from personal injury cases like car accidents to medical malpractice. One of the foremost advocates of this idea, Professor Jennifer Robbennold of the University of Illinois College of Law, has published the results of a variety of empirical studies showing that apologies effectively encourage settlement of civil disputes. But practical barriers to getting defense counsel to encourage clients to apologize exist. The biggest issue is the fact that such hearsay can be ...

Every winter, weather forecasters talk about the snow cover in the northern U.S. and into Canada as a factor in how deep the deep-freeze will be in the states. A new study by researchers at the University of Georgia indicates they may be looking, at least partially, in the wrong place. It turns out that snow piling up over a band of frozen tundra from Siberia to far-northern Europe may have as much effect on the climate of the U.S. as the much-better-known El Niño and La Niña. The new work, just published in the International Journal of Climatology, reports that to ...

When automobile accidents occur, drivers or their insurance companies, or both, are typically liable for any injury or property damage. However, when minor drivers are involved in car accidents, who is responsible for the resulting costs? In some states, like Colorado, the liability may fall on the parents, who may or may not have heard about a law known as the family car doctrine. Parents should know this law's main points and how to financially protect themselves if their children are involved in automobile accidents while driving. Family Car Doctrine About 20 ...

New Rochelle, NY, June 24, 2011—Basal insulin analogs have revolutionized diabetes care, and especially the treatment of type 2 diabetes, enabling patients to achieve better control of blood glucose levels while reducing hypoglycemic episodes. These revolutionary, long-acting basal insulin analogs, intended to replace the natural insulin missing in diabetes, and infusion pumps that provide subcutaneous, continuous delivery of insulin to mimic the function of a normal pancreas, are described in a special supplement to Diabetes Technology & Therapeutics, a peer-reviewed journal ...

They can be found everywhere—organized communities of bacteria sticking to surfaces both inside and outside the body. These biofilms are responsible for some of the most virulent, antibiotic-resistant infections in humans; however, scientific understanding of how these communities develop is lacking. A recent study led by a Syracuse University biologist sheds new light on the process. The scientists discovered that a complex cascade of enhancer binding proteins (EBPs) is responsible for turning on genes that initiate the formation of a biofilm. The study was published ...

PITTSBURGH, June 24 – The life expectancy of people diagnosed with type 1 diabetes dramatically increased during the course of a 30-year, long-term prospective study, according to a University of Pittsburgh Graduate School of Public Health study being presented at the 71st Scientific Sessions of the American Diabetes Association. The life expectancy for participants diagnosed with type 1 diabetes between 1965 and 1980 was 68.8 years – a 15-year improvement, compared to those diagnosed between 1950 and 1964, according to the study. Meanwhile, the life expectancy of the ...

NASA infrared satellite imagery today shows the Meari is stronger than Haima. Tropical Storm Haima has maximum sustained winds near 35 knots (40 mph/65 kmh) making it a minimal tropical storm tracking toward Vietnam. Tropical Storm Meari is a stronger storm, with maximum sustained winds near 55 knots (63 mph/101 kmh). At 1500 UTC (11 a.m. EDT) on June 24 Meari's center was about 250 nautical miles southwest ...

CORPUS CHRISTI – As billion-dollar agricultural losses continue to mount in the withering Texas heat, Texas AgriLife Research scientists in Corpus Christi are taking a closer look at why some cotton varieties do better than others in drought conditions. "We want to better understand those traits that control water use in plants so we can transfer that information to breeders and geneticists to more quickly develop drought-tolerant cultivars so badly needed here," said Dr. Carlos Fernandez, a plant physiologist at the Texas AgriLife Research and Extension Center in Corpus ...
