GALVESTON, Texas -- For thousands of years, people have believed that eating large amounts of protein made it easier to build bigger, stronger muscles.
RIVERSIDE, Calif. -- An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies.
WESTCHESTER, Ill. -- Computer/console gamers who play for more than seven hours a week and who identify their gaming as an addiction sleep less during the weekdays and experience greater sleepiness than casual or non-gamers, according to a research abstract that will be presented on Monday, June 8 at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies
University of Arkansas researchers have characterized a membrane receptor protein and its binding mechanism from chloroplasts in plants and determined that it shares a commonly shaped binding site and mechanism with a similar protein found in E. coli.
Fast food and soft drinks may be making children fatter but they also make them happy.
As more and more Americans eat meals outside the home, the country also faces an epidemic of obesity. An association between eating out and weight-related diseases has led to demands for nutritional labeling of restaurant foods. A new study in the Journal of Consumer Research examines the potential benefits of such labeling.
physicists have discovered a new phase in tiny nanodisks and nanorods that potentially may enable researchers to increase memory storage by more than one thousand fold. This finding also opens a new area in physics to fundamental investigation. ''This ordered phase with technological relevance is previously unknown... The new phase is possible because the nano-size of the disks wouldn't allow disorder due to properties no one has characterized before.''
Nearly one-third of patients with advanced multiple myeloma who had failed current standard therapy of chemotherapy or stem cell transplantation responded to thalidomide for a median duration of nearly one year in a Mayo Clinic study of the effects of thalidomide on myeloma. The findings are reported in the January issue of Mayo Clinic Proceedings.
Many studies in the last three years have determined that thalidomide is effective in the treatment of multiple myeloma, following the initial report by researchers at the University of Arkansas. However, information is limited on how long thalidomide therapy works and on survival rates with such therapy.
A new study by a University of Arkansas psychologist proposes that beliefs about the afterlife may amount to more than a cultural construct. They may in fact have a biological basis ? arising from the human brain's unique ability to comprehend the mental states of other people. "The vast majority of cultures, if not all of them, have developed some theory about what happens to personal consciousness after death. Even in our own culture, 82 percent of Americans believe in some form of personal continuation after death," said the study's lead author. "There are superficial differences in religious beliefs between cultures, but those all arise out of the same question. Beliefs in an afterlife ? or at least thoughts about life after death ? are both universal and natural."
The energy required to create an accurate quantum computer may limit the ability of scientists to make these novel devices small, fast, cheap and efficient, says a University of Arkansas researcher. Quantum computing relies on using single atomic particles as units for information storage. Manipulating this information requires pulsed electromagnetic fields?which contain energy. The researcher found that the energy needed to perform a calculation is inversely proportional to the error rate: In other words, more energy means less uncertainty.
A completely new type of therapy, using a unique class of synthetic compounds, may someday protect both men and women from the bone-weakening disease osteoporosis. Researchers reported in the October 25 issue of Science that early studies of one of these compounds called estren successfully preserved and even restored bone mass in an animal model without the side effects associated with sex hormone therapies.
