Foreign doctors up in arms over new UK immigration rules

The National Health Service (NHS) in the UK appears to stagger from one crisis to another, and now hundreds of overseas doctors have staged a demonstration outside the Department of Health over a change in the immigration rules which will force many of them to leave the UK.

Kidney treatments may be improved with new understanding of cell death mechanism

Finding how two proteins conspire to get kidney cells to self-destruct when oxygen supplies are low may one day improve dismal mortality rates for ischemic renal failure, researchers say.

Poor health related to inadequate housing for immigrant farmworkers in the USA

Many Hispanic farmworker families in North Carolina live in inadequate housing that puts them at higher risk of exposure to disease, toxins and overcrowding that can affect their psychological well-being, according to new research by Wake Forest University School of Medicine.

Foot problems change social behaviour - but it doesn't have to be that way

With the average person taking 9,000 steps per day -- more than 600 miles each year -- when feet start to hurt or change in shape, it can really impact a person's life. In fact, according to a new survey, of people who report having foot issues in the past five years, two out of three report that these foot issues, which range from blisters to bunions and heel pain, have changed the kind of shoes they wear, how active they are, where and how far they walk, and so on.

Bullying pushes overweight kids away from sport, increasing health problems

Most kids are bullied at some point in their lives, but overweight children are more often the targets of bullies' slings and arrows. Now a new UF study reveals this frequently leads them to avoid situations where they have been picked on before, such as gym class and sports.

Yale researchers show how smell works within the brain

Yale scientists have systematically plotted the responses of the entire Drosophila (fruit fly) olfactory system, providing the first multi-dimensional map of the range of odorants sensed and the regions of the brain that are stimulated.

Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .

Concerns for inexpensive fertility drug appears to be unfounded

Concerns about the use of letrozole, an easy-to-use and inexpensive drug for the treatment of infertility, appear to be unfounded, according to a major study co-authored by Dr. Togas Tulandi, Director of Division of Reproductive Endocrinology and Infertility, McGill University Health Centre (MUHC) and Chief of Obstetrics and Gynecology at the Jewish General Hospital, and Professor of Obstetrics and Gynecology at McGill University.

Birth defects from rubella almost eradicated in the USA

Congenital rubella syndrome, a birth defect caused by the rubella virus (also known as German measles), has practically been eliminated in the U.S., according to a statement published in the April 2006 issue of Birth Defects Research Part A, the official journal of The Teratology Society.

Penn researchers discover gene that creates "second skeleton" bone disorder

Researchers at the University of Pennsylvania School of Medicine have located the "skeleton key," a gene that, when damaged, causes the body's skeletal muscles and soft connective tissue to undergo a metamorphosis into bone, progressively locking joints in place and rendering movement impossible.

Research sheds light on eating disorders, compulsive gambling and drug abuse

Researchers at Harvard Medical School (HMS) report in the April 23 issue of Nature that they have identified neurons that encode the values that subjects assign to different items. The activity of these neurons might facilitate the process of decision-making that occurs when someone chooses between different goods.

Scientists clarify role of phosphatase and tensin homolog tumor suppressor gene

Jiwang Zhang, Ph.D., formerly a Senior Research Associate at the Stowers Institute for Medical Research, and Linheng Li, Ph.D., Associate Investigator, are credited as the first and last authors, respectively, on a paper highlighting several previously unknown functions of phosphatase and tensin homolog (PTEN), an important tumor suppressor gene.

Study reveals findings on how insulin-producing beta cells grow and function

A new Joslin Diabetes Center-led study has shown conclusively that two receptors in the insulin-producing beta cell do not affect developmental growth, refuting a long-held hypothesis in diabetes research.

A TAS1R receptor-based explanation of sweet water taste

A scientific paradox linking artificial sweeteners such as saccharin with a sensory experience in which plain water takes on a sweet taste has guided researchers to an increased understanding of how humans detect sweet taste.

Discovery of the molecular mechanisms that allow animals to switch genes on or off to gain or lose anatomical characteristics

Anatomical features, scientists know, come and go. The animal kingdom is full of critters that have independently gained or lost similar features. Whales and snakes, for instance, have lost their legs. Winged flight evolved separately in birds, bats and pterosaurs at different times in evolutionary history.
