Regular, moderate exercise does not worsen pain in people with fibromyalgia

WINSTON-SALEM, N.C., – May 2, 2013 – For many people who have fibromyalgia, even the thought of exercising is painful.

Yet a new study from Wake Forest Baptist Medical Center shows that exercise does not worsen the pain associated with the disorder and may even lessen it over time. The findings are published in the current online issue of the journal Arthritis Care & Research.

Persistent pain after stressful events may have a neurobiological basis

CHAPEL HILL, N.C. – A new study led by University of North Carolina School of Medicine researchers is the first to identify a genetic risk factor for persistent pain after traumatic events such as motor vehicle collision and sexual assault.

In addition, the study contributes further evidence that persistent pain after stressful events, including motor vehicle collisions and sexual assaults, has a specific biological basis. A manuscript of the study was published online ahead of print by the journal Pain on April 29.

More effective, cheaper concrete manufactured with ash from olive residue biomass

University of Granada researchers have successfully manufactured self-compacting concrete using ash from the combustion of olive pruning residue pellets. Due to its plasticity and cohesion, this type of concrete needs no compaction when used in construction and has many advantages over conventional concrete, resulting in considerable savings of time and money.

Is the humble fig more than just a fruit?

Figs and fig trees are familiar to a wide cross-section of human society, both as a common food and for their spiritual importance. What is less well understood is the global nature of this association between figs and humans, which is maintained across species, continents and societies. This relationship is explored by David Wilson of Ecology and Heritage Partners and Anna Wilson from the University of Melbourne in Australia in a paper published in the Springer journal Human Ecology.

On-site asbestos detector offers promise of better workplace safety

WASHINGTON, May 2, 2013—Asbestos was once called a miracle material because of its toughness and fire-resistant properties. It was used as insulation, incorporated into cement and even woven into firemen's protective clothing. Over time, however, scientists pinned the cause of lung cancers such as mesothelioma on asbestos fiber inhalation. Asbestos was banned in the many industrialized countries in the 1980s, but the threat lingers on in the ceilings, walls and floors of old buildings and homes. Now a team of researchers from the University of Hertfordshire in the U.K.

Study uncovers mechanism for how grapes reduce heart failure associated with hypertension

A study appearing in the Journal of Nutritional Biochemistry¹ demonstrates that grapes are able to reduce heart failure associated with chronic high blood pressure (hypertension) by increasing the activity of several genes responsible for antioxidant defense in the heart tissue. Grapes are a known natural source of antioxidants and other polyphenols, which researchers believe to be responsible for the beneficial effects observed with grape consumption.

3D simulation shows how form of complex organs evolves by natural selection

Researchers at the Institute of Biotechnology at the Helsinki University and the Universitat Autònoma de Barcelona (UAB) have developed the first three-dimensional simulation of the evolution of morphology by integrating the mechanisms of genetic regulation that take place during embryo development. The study, published in Nature, highlights the real complexity of the genetic interactions that lead to adult organisms' phenotypes (physical forms), helps to explain how natural selection influences body form and leads towards much more realistic virtual experiments on evolution.

New genetic clues to breast and ovarian cancer

A major international study involving a Simon Fraser University scientist has found that sequence differences in a gene crucial to the maintenance of our chromosomes' integrity predispose us to certain cancers.

Angela Brooks-Wilson, an associate professor in SFU's biomedical physiology and kinesiology department and a Distinguished Scientist at the BC Cancer Agency, is one of more than 600 scientists globally who contributed to this study.

New imaging technique to visualize bio-metals and molecules simultaneously

Metal elements and molecules interact in the body but visualizing them together has always been a challenge. Researchers from the RIKEN Center for Life Science Technologies in Japan have developed a new molecular imaging technology that enables them to visualize bio-metals and bio-molecules simultaneously in a live mouse. This new technology will enable researchers to study the complex interactions between metal elements and molecules in living organisms.

No greater death risk for children admitted to emergency out-of-hours intensive care

Children admitted to UK intensive care units in out-of-hours emergencies are at no greater risk of dying than children arriving during normal working hours, according to new research.

However, mortality rates are significantly higher in the winter, even after taking into account added health risks for children in the colder months.

Exercise proves to be ineffective against care home depression

Researchers at the University of Warwick and Queen Mary, University of London have shown that exercise is not effective in reducing burden of depression among elderly care home residents.

Exercise is a low risk intervention that can improve mental health but the findings of a National Institute for Health Research Health Technology Assessment Programme study, published in The Lancet, conclude that there is a requirement for alternative approaches to reduce the burden of depression in frail, very elderly, care home residents.

1 bad gene: Mutation that causes rare sleep disorder linked to migraines

SALT LAKE CITY)—A gene mutation associated with a rare sleep disorder surprisingly also contributes to debilitating migraines, a new discovery that could change the treatment of migraines by allowing development of drugs specifically designed to treat the chronic headaches.

Taking cholesterol-lowering drugs may also reduce the risk of dying from prostate cancer: Study

SEATTLE – Men with prostate cancer who take cholesterol-lowering drugs called statins are significantly less likely to die from their cancer than men who don't take such medication, according to study led by researchers at Fred Hutchinson Cancer Research Center. The findings are published online today in The Prostate.

Primate hibernation more common than previously thought

DURHAM, N.C. -- Until recently, the only primate known to hibernate as a survival strategy was a creature called the western fat-tailed dwarf lemur, a tropical tree-dweller from the African island of Madagascar.

Study finds key protein for firing up central nervous system inflammation

HOUSTON – Scientists have identified an influential link in a chain of events that leads to autoimmune inflammation of the central nervous system in a mouse model of multiple sclerosis (MS).

An international team of researchers led by scientists in The University of Texas MD Anderson Cancer Center Department of Immunology reported their results in an advance online publication in Nature Medicine.
