Multi-species genome comparison sheds new light on evolutionary processes

An international team that includes researchers from the National Human Genome Research Institute (NHGRI) has discovered that mammalian chromosomes have evolved by breaking at specific sites rather than randomly as long thought - and that many of the breakage hotspots are also involved in human cancer.

Scientists have identified the first genetic mutations that cause the aorta to widen, tear and rupture

Finding biological markers that flag aneurysm, a bulging of the aorta that leads to dissection, a lengthwise separation of tissues in the artery wall, is critically important for early diagnosis.

Fragile X-associated tremor/ataxia syndrome difficult to diagnose

Fragile X-associated tremor/ataxia syndrome can be difficult to diagnose and should have guidelines for diagnostic testing, according to a study in the July 26 issue of Neurology, the scientific journal of the American Academy of Neurology. A second study found chemotherapy aggravated symptoms in one woman's case.

Bodily illusions rearrange the sense of touch

The brain is bombarded by information about the physical proportions of our bodies. The most familiar sensations, such as a puff of wind or the brush of our own shirt sleeve, serve to constantly remind the brain of the body's outer bounds, creating a sense of what is known as proprioception.

New insight into age-related macular degeneration

Age-related macular degeneration is the leading cause of blindness in older adults, yet researchers are still in the dark about many of the factors that cause this incurable disease.

Multiple rare mutations within a single gene may increase risk for autism

While debate still rages over the 'cause' of autism, mounting evidence suggests that genetic factors play a major role in the disease.

Breathing in large quantities of salt particles has just the same effect on blood pressure as eating a salty diet

Workers in salt factories, who inhale large amounts of salt particles, are at risk of high blood pressure due to the increased salt intake.

Variation in HIV's ability to disable host defenses contributes to rapid evolution

One of the reasons HIV is so difficult to contain and treat is its rapid evolution. Understanding how host defenses and viral countermeasures contribute to that evolution is vital.

Percutaneous core-needle biopsy, provides samples of tissue suitable for accurate initial diagnosis of a solid tumor

Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital.

Plant toxins in the diets of early humans drove the evolution of taste

Plant toxins in the diets of early humans drove the evolution of a bitter taste receptor better able to detect them, suggests new genetic research by scientists at University College London, Duke University Medical Center, and the German Institute of Human Nutrition.

In vivo engineering of organs: The bone bioreactor

An international team of biomedical engineers has demonstrated for the first time that it is possible to grow healthy new bone reliably in one part of the body and use it to repair damaged bone at a different location.

Study offers a unique perspective on the beginnings of the alcohol experience and usage patterns of 12-year-olds

Clues looking into the root causes of alcoholism are emerging from new findings that center on the genetic patterns of young drinkers, with particular focus on why adolescents are more likely to drink large quantities of alcohol even if they need more alcohol to get the effects they desire.

Pneumonia - another use for statins

Patients hospitalised because of pneumonia are at less risk of dying from the disease if they have been taking the widely used cholesterol-lowering drugs 'statins' before hospital admission.

New treatment that boosts the stomach's 'full' signal offers new way of tackling growing obesity epidemic

A hormone found in the small intestine has provided a crucial breakthrough in developing new drugs to tackle the growing obesity epidemic, claim scientists. Obesity now affects more than half of all UK adults, costing the UK up to 3.7 billion pounds a year in sickness absence and treatments.
