Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes’ nearly friction-free surface, researchers at the University of Kentucky report in the Nov. 3 issue of Nature.
In their study, Mainak Majumder, Nitin Chopra and Bruce J. Hinds of UK’s Chemical and Materials Engineering Department, and Rodney Andrews of UK’s Center for Applied Energy Res
Families living in the Nellies Cave Park area near Virginia Tech are helping researchers learn about healthy lifestyles and in return are getting information about their own health.
The project by nutrition researchers from Virginia Tech’s College of Agriculture and Life Sciences is part of efforts to learn how a neighborhood influences physical activity and diet.
“We think that town planners, zoning administrators, parks and recreation planners and other communit
New research findings showcased at the 13th European Cancer Conference (ECCO) have highlighted the important therapeutic potential of immunotherapy in the treatment of a number of different cancers e.g. for treatment of renal and skin cancers.
Renal cancer is the 6th leading cause of cancer death with a survival rate of 11% for stage-IV disease. More than a million skin cancer cases occur each year globally, with a 5-year survival rate of 7 to 9% and a 10-year survival rate of 3 to
Studies in monkeys and women suggest that unlike traditional estrogen therapy, a diet high in the natural plant estrogens found in soy does not increase the risk of uterine cancer in postmenopausal women, according to Mark Cline, D.V.M., Ph.D., an associate professor of comparative medicine at Wake Forest University Baptist Medical Center.
“These findings give us some confidence that dietary soy doesn’t promote uterine cancer and, in fact, may offer a protective effect in some cas
Aerobic exercise is thought to help persons with multiple sclerosis fight fatigue, the most common symptom of the disease. Yet MS also appears to cause the body to heat up more quickly, compromising the ability to exercise.
New research at UB will investigate if cooling the body before or during exercise allows persons with MS to exercise longer, and which method is most effective. The study also will determine the effects of a 12-week aerobic exercise program on fitness, cor
Visual information is processed even when the visual cortex is temporarily shut down
Visual information can be processed unconsciously when the area of the brain that records what the eye sees is temporarily shut down, according to research at Rice University in Houston.
The research, published the week of Oct. 31 in the Proceedings of the National Academy of Sciences’ (PNAS) online Early Edition, suggests the brain has more than one pathway along which visual inform
After a person is diagnosed with cancer, increased surveillance among their family members may result in the earlier detection of asymptomatic familial cancers. This phenomenon is called detection bias and may occur for a variety of cancers, according to a new study in the November 2 issue of the Journal of the National Cancer Institute.
Accurate assessments of the risk of cancer among the family members of cancer patients are essential for clinical and genetic counseling. Knowl
They might prefer to be in front of the TV or Playstation, but Brisbane teenagers are likely to be healthier if they eat meals with mum and dad.
University of Queensland researchers working on the world’s longest health study found teens who ate regularly with their family were less likely to be overweight.
Lead researcher, Dr Abdullah Al Mamun from UQ’s School of Population Health said regular family meals could reduce snacking and make for healthier food a
Study results presented at the 13th European Cancer Conference (ECCO 13) have provided further valuable insights into certain genetic mutations which occur in childhood thyroid tumours and their link to both radiation exposure and patient age.
The unique circumstances of this study were provided for by the legacy of the radioactive accident at Chernobyl Nuclear Power Plant in April 1986. Exposure to radioactive fallout led to a large increase in the incidence of papillary th
New research shows that idiopathic interstitial pneumonia (IIP), a group of potentially fatal disorders that affects the lungs, may be caused by an interaction between a specific genetic background and cigarette smoking. In a study of 111 families that had at least two relatives with IIP, people who smoked cigarettes were three times more likely than non-smokers to develop the disease. The research was supported by the National Heart, Lung, and Blood Institute (NHLBI) and the National Institute
Experiments in female monkeys have for the first time shown that when used in combination, vaginal gels known as microbicides can protect against an HIV-like virus. The research, funded largely by the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), suggests that similar combination microbicides could potentially provide a safe, effective and practical way to prevent HIV transmission to women, according to study investigators.
The Center for Health and the Global Environment at Harvard Medical School, along with co-sponsors Swiss Re and the United Nations Development Programme, today released a study showing that climate change will significantly affect the health of humans and ecosystems and these impacts will have economic consequences. The study, entitled “Climate Change Futures: Health, Ecological and Economic Dimensions,” surveys existing and future costs associated with climate change and the growing potential
Nearly one-fourth of all dialysis patients have a close relative on dialysis, researchers at Wake Forest University Baptist Medical Center, and others, report in the current online edition of the American Journal of Nephrology. The researchers suggest screening other relatives for undetected kidney disease.
Barry I. Freedman, M.D., reports that many relatives in these families have silent kidney diseases that can be treated at early stages, leading to slowed progression or prevent
A new study of genetic changes in bacteria may ultimately help drug makers stay a step ahead of disease-causing bacteria that can become resistant to antibiotics.
The secret lies in understanding the function of the ribosome, a tiny protein-making factory residing inside most cells.
Many currently used antibiotics alter a ribosome’s ability to make proteins, said Kurt Fredrick, a study co-author and an assistant professor of microbiology at Ohio State University.
Breastfeeding does not raise the risk of mother-to-child transmission of hepatitis C virus (HCV), according to two new studies published in the December 1 issue of The Journal of Infectious Diseases, now available online.
One study found that infant girls are twice as likely to be infected as infant boys. Both studies provide new information with which to counsel pregnant women infected with HCV. Taken together, the two new studies expand upon preliminary data from smaller studies
From glaciers to caribou, rivers to roads, Arctic climate change is having a broad effect on almost every aspect of life in the North. That’s the conclusion University of Alaska Fairbanks researchers and others outline in a paper to be published in the October 2005 issue of the journal “Climatic Change.”
The paper is a result of decades of research by dozens of scientists in multiple disciplines, said Larry Hinzman, a research professor with UAF’s Water and Environmental Research
