Children's sexuality linked to genetic influences: Study

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.

Genetic switch that causes excessive mucus in the lungs identified

Scientists have identified the main genetic switch that causes excessive mucus in the lungs, a discovery that one day could ease suffering for people with chronic lung diseases like asthma and cystic fibrosis, or just those fighting the common cold.

People with smaller anterior cruciate ligaments are more prone to injury

A study comparing images of the knees in people who did and didn't have previous injuries to the anterior cruciate ligament suggests that people who tore their ACLs are more likely to have a smaller ligament than do similarly sized people who have never injured a knee.

New protein substance could be used to diagnose Alzheimer's disease

Gothenburg researchers have discovered a previously unknown substance in spinal fluid that can be used to diagnose Alzheimer's disease. The findings, described in a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden, will also be useful in research on new medications.

Carotid and cardiac procedures result in higher incidence of post-operative strokes

Among patients undergoing cardiac surgery, post-operative stroke occurred in approximately 2 percent, was not correlated with significant carotid artery narrowing, but was more common among patients who had combined cardiac and carotid procedures, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals.

Centre of consciousness may lead to new coma treatments

A new understanding of how anesthesia and anesthesia-like states are controlled in the brain opens the door to possible new future treatments of various states of loss of consciousness, such as reversible coma, according to Hebrew University of Jerusalem scientists.

New findings could yield effective therapies for multiple sclerosis

A Mayo Clinic study has found that two genes in mice were associated with good central nervous system repair in multiple sclerosis (MS). These findings give researchers new hope for developing more effective therapies for patients with MS and for predicting MS patients' outcomes.

Body mass in younger and older adulthood linked to prostate cancer risks

A team of scientists led by researcher Brenda Hernandez, Ph.D., M.P.H.-an assistant professor at the University of Hawai'i at Mānoa's Cancer Research Center of Hawai'i-has reported that body mass in younger and older adulthood, and weight gain between these life periods, may influence a man's risk for prostate cancer. This risk varies among different ethnic groups, according to findings reported in a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Master gene could lead to new ways of cancer treatments

The master gene that causes blood stem cells to turn into disease-fighting 'Natural Killer' (NK) immune cells has been identified by scientists, in a study published in Nature Immunology today. The discovery could one day help scientists boost the body's production of these frontline tumour-killing cells, creating new ways to treat cancer.

Research data reveals why women discontinue treatment with current osteoporosis therapies

Amgen Inc. today announced the presentation of data highlighting the links between medication satisfaction, adherence to therapy and fracture risk reduction among women with postmenopausal osteoporosis. The data were presented at the 31st annual meeting of the American Society for Bone Mineral Research (ASBMR).

AAN's ability to mimic the human brain helps diagnose cardiac infections

Mayo Clinic researchers say that "teachable software" designed to mimic the human brain may help them diagnose cardiac infections without an invasive exam. Those findings are being presented today at the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in San Francisco.

Monoamine oxidases responsible for personality and behaviour

Antisocial and aggressive behaviours represent a widespread and expensive social problem. Recent research has convincingly shown that there is a strong interaction between genetic inheritance and environment for development of personality and behaviour.

ERC funds DiaDrug project to study the link between insulin resistance and albuminuria

The European Research Council (ERC) expects to fund some 240 top researchers in its second prestigious ERC Starting Grant competition. This new wave of grantees follows the 299 researchers who received grants in the first Starting Grant competition in 2007. In total, 2503 proposals were submitted to the second Starting Grant call.

Second-hand tobacco smoke exposure results in NAFLD

A team of scientists at the University of California, Riverside has found that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury in which fat accumulates in the liver of people who drink little or no alcohol.

Social identity has a positive impact on health and well-being

The quality of a person's social life could have an even greater impact than diet and exercise on their health and well-being. There is growing evidence that being a member of a social group can significantly reduce the risk of conditions like stroke, dementia and even the common cold.

Swine flu more lethal than seasonal flu

Pandemic swine flu can infect cells deeper in the lungs than seasonal flu can, according to a new study published today in Nature Biotechnology. The researchers, from Imperial College London, say this may explain why people infected with the pandemic strain of swine-origin H1N1 influenza are more likely to suffer more severe symptoms than those infected with the seasonal strain of H1N1.
