Researchers in Japan and Canada have discovered a key component of the quality control mechanism that operates inside human cells – sometimes too well. The breakthrough has significant implications for the development of new treatments for cystic fibrosis (CF) and some other hereditary diseases, the researchers say. Their results were published July 25 in the journal Science.

The majority of general internists and pediatricians in the United States are not comfortable serving as primary care providers for young adults with complex chronic illnesses that originate during childhood, according to findings from a new national survey.

CHAMPAIGN, Ill. — Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering. To further improve the technique's sensitivity, scientists must design better scattering surfaces, and more effective ways of evaluating them.

Less able to achieve their life goals, women end up unhappier than men later in life – even though they start out happier, reveals new research by Anke Plagnol of the University of Cambridge, and University of Southern California economist Richard Easterlin.

Plagnol and Easterlin's study, forthcoming in the Journal of Happiness Studies, is the first to use nationally representative data spanning several decades to examine the role of unfulfilled desires in a person's sense of well-being.

July 25, 2008 -- Medical physicists at the University of Virginia have created a novel way to kill tumor cells using nanoparticles and light. The technique, devised by Wensha Yang, an instructor in radiation oncology at the University of Virginia, and colleagues Ke Sheng, Paul W. Read, James M. Larner, and Brian P. Helmke, employs quantum dots. Quantum dots are semiconductor nanostructures, 25 billionths of a meter in diameter, which can confine electrons in three dimensions and emit light when exposed to ultraviolet radiation.

Family, friends and neighbors remember Lisa Sandler Spaeth as an active mother of two in Potomac, Md., with a lot on the go, juggling her son's baseball games and her daughter's horseback-riding lessons with numerous committee obligations, organizing women's activities at her local synagogue. Add to this Spaeth's thriving home business turned wholesale supplier - making custom hair accessories for children - which she founded with her mother.

There is a link between alcohol consumption and increased risk of perennial allergic rhinitis, according to a recent Danish study of 5,870 young adult women. The study, published in the July issue of Clinical and Experimental Allergy, found that the risk increased 3% for every additional alcoholic drink per week. In contrast, the authors did not observe any increase in risk of seasonal allergic rhinitis according to alcohol intake.

CLEVELAND—After weeks of bed rest during pregnancy, new mothers need to rebuild muscles and strengthen their stamina. Now a group of women will test new interventions in aiding that recovery during a pilot study at Case Western Reserve University's Frances Payne Bolton School of Nursing.

Leipzig. For the first time an international researcher team has developed a model, which identifies potential habitats and corridors for the European wildcat (Felis silvestris silvestris). Using Rheinland-Pfalz as an example, it was demonstrated that almost half of this German federal state could be suitable for wildcats, enabling a maximum population of 1600 females.

Researchers at the University of Adelaide have developed a novel approach to treating advanced prostate cancer that could be more effective with fewer side effects.

Professor Wayne Tilley and Dr Lisa Butler of the University's Dame Roma Mitchell Cancer Research Laboratories have discovered that by using existing prostate cancer drugs in combination with new drugs at lower doses, they can expect to generate better results for patients than current treatments.

Millions of people world-wide who have contracted a highly resistant strain of the HIV virus could benefit from a new drug to treat the infection.

Research co-authored by the University of New South Wales' (UNSW) National Centre in HIV Epidemiology and Clinical Research (NCHECR) shows that the majority of patients who have not responded to traditional treatments have had good results from a new combination therapy.

Infection with HIV could quadruple in certain populations if people with HIV follow potentially misleading advice contained in a statement from the Swiss Federal Commission for HIV/AIDS, University of New South Wales (UNSW) research warns.

Long-suffering victims of allergies such as asthma and hay fever might enjoy a surprise benefit, according to research led by the University of New South Wales (UNSW).

In a paper presented at an international symposium in Sydney, the researchers show that people with one of these atopic diseases are up to 25 percent less likely to get the most common type of Non-Hodgkin Lymphoma (NHL).

The InterLymph Symposium is co-hosted by the Leukaemia Foundation, the Cancer Institute NSW, UNSW and the National Centre in HIV Epidemiology and Clinical Research.

The race to ensure that scientists stop drug-taking athletes from damaging sport by using performance enhancing drugs or undergoing genetic manipulation is a constant challenge, according to a major four-decade review by three of the World's leading experts on doping in sport.

By absorbing carbon dioxide from the atmosphere, and from the human use of fossil fuels, the world's seas function as a giant buffer for the Earth's life support system. The chemical balance of the sea has long been regarded as immovable. Today, researchers know that the pH of the sea's surface water has gone down by 0.1, or 25 percent, just since the beginning of industrialisation just over a century ago.
