Los Angeles, London, New Delhi, Singapore and Washington DC (October 22, 2009) The rates of non-familial sex crimes against children under the age of 12 are no higher during the Halloween season than at any other times of the year, according to a study published in the September issue of Sexual Abuse: A Journal of Research and Treatment the official journal of the Association for the Tre
OKLAHOMA CITY -- Researchers at the University of Oklahoma Health Sciences Center are helping to lead a massive international study on the possible genetic effects of radiation and cancer drug exposures on future generations.
Previous research has found that children raised in homes without a biological father have sex earlier than children raised in traditional nuclear families. Now a new study that used a novel and complex design to investigate why this is so challenges a popular explanation of the reasons.
Tropical lizards detect the effects of global warming in a climate where the smallest change makes a big difference, according to herpetologist Laurie Vitt, curator of reptiles and George Lynn Cross Research Professor at the University of Oklahoma's Sam Noble Museum of Natural History.
OKLAHOMA CITY -- Researchers at the University of Oklahoma Health Sciences Center have shown the first link between a newly discovered anti-aging gene and high blood pressure. The results, which appear this month in the journal Hypertension, offer new clues on how we age and how we might live longer.
At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from. Did our ancestors come from Europe or Asia? As curious as we are about our ancestors, for practical purposes, we need to think about the ancestry of our genes, according to Cecil Lewis, assistant professor of anthropology at the University of Oklahoma.
OKLAHOMA CITY -- The dean of the University of Oklahoma College of Public Health and a team of scientists worldwide have found a better way to prevent deadly blood clots after joint replacement surgery -- a major problem that results in thousands of unnecessary deaths each year. The research appears this week in the New England Journal of Medicine.
OKLAHOMA CITY -- Scientists at the University of Oklahoma Health Sciences Center have found that playing active video games can be as effective for children as moderate exercise. The findings appear this week in the journal Pediatrics from the American Academy of Pediatrics.
A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. Determining how Rydberg molecules interact is important because Rydberg atoms are a key ingredient in atom based quantum computation schemes.
NORMAN, Okla. -- Representatives from the University of Oklahoma College of Atmospheric and Geographic Sciences presented recommendations for a comprehensive modernization of the Croatian Meteorological and Hydrological Service (DHMZ - Dr?avni hidrometeorolo?ki zavod) to the government of the Republic of Croatia in Zagreb, Croatia, on June 18.
A new study from North Carolina State University is turning the conventional wisdom about technology start-up companies on its head, showing that ventures with moderate levels of undercapitalization can still be successful and that a great management team is not more important than a top-notch technology product when it comes to securing sufficient amounts of capital.
A rare "Rydberg" molecule discovered by scientists from the University of Stuttgart and University of Oklahoma upheld scientific theory predicting the molecule existed. The team used a gas of rubidium atoms cooled to a temperature of 3 millionths of a degree above absolute zero to produce the molecule. The longest-lived molecule produced by the team survived only for 18 microseconds.
An article published this week in the journal Nature provides the first experimental evidence for an unusual molecular bonding mechanism that could explain how certain cells adhere to surfaces such as blood vessel walls under conditions of mechanical stress. Known as "catch bonds," the adhesion mechanism displays surprising behavior, prolonging rather than shortening the lifetimes of bonds between specific molecules as increasing force is applied. Proposed theoretically nearly 15 years ago, catch bonds could help explain how the body regulates the activity of white blood cells, which must flow freely through blood vessels -- yet bond to injury sites despite blood flow forces.
Researchers in Oklahoma have deciphered the complete genome sequence of Streptococcus mutans, the main organism implicated in causing tooth decay. The work, supported by the National Institute of Dental and Craniofacial Research, has been made freely available online. Said one of the team members involved in the four-year effort: "Building on this basic research may one day lead us to new approaches for preventing and treating tooth decay." Added another: "By targeting the adherence genes, for example, we might be able to develop a way of preventing S. mutans from sticking to teeth."
