Gene study gives insight into causes of a common type of arthritis
A series of genetic variants associated with the joint disorder ankylosing spondylitis has been identified in a study involving Oxford University researchers. The findings provide new clues as to how the condition may be treated in the future. The study, a collaboration between the Australo-Anglo-American Spondyloarthritis Consortium and the Wellcome Trust Case Control Consortium, also provides one of the first confirmed examples of gene-gene interaction seen in humans.

How best to excite brain cells
ANN ARBOR, Mich.—Oh, the challenges of being a neuron, responsible for essential things like muscle contraction, gland secretion and sensitivity to touch, sound and light, yet constantly bombarded with signals from here, there and everywhere. How on earth are busy nerve cells supposed to pick out and respond to relevant signals amidst all that information overload' Somehow neurons do manage to accomplish the daunting task, and they do it with more finesse than anyone ever realized, new research by University of Michigan mathematician Daniel Forger and coauthors demonstrates.

Indoor air pollution linked to cardiovascular risk
An estimated two billion people in the developing world heat and cook with a biomass fuel such as wood, but the practice exposes people — especially women — to large doses of small-particle air pollution, which can cause premature death and lung disease. In a study just published online in the peer-reviewed journal Environmental Health Perspectives, researchers at the University of Wisconsin-Madison have associated indoor air pollution with increased blood pressure among older women.

Sunburn study could lead to new pain relief
Researchers at King's College London have found a molecule in the body which controls sensitivity to pain from UVB irradiation, identifying it as a new target for medicines to treat pain caused by other common inflammatory conditions such as arthritis. The molecule, called CXCL5, is part of a family of proteins called chemokines, which recruit inflammatory immune cells to the injured tissue, triggering pain and tenderness.

Innovation marks UW-Madison contribution to vitamins, drugs, medical supplies
With a long tradition of exploration of medicine and biology, and a research budget that has passed $1 billion, University of Wisconsin-Madison builds on a rich history of discoveries related to drugs and nutrition: Vitamin A and B were discovered here in 1914. In 1941, Karl Paul Link discovered coumarin, from which he synthesized the first widely effective rat poison, commonly known as Warfarin, and later the first medically safe and still widely used anticoagulant.

New research redraws pancreas anatomy
Research from Karolinska Institutet shows that insulin secretion in the pancreas is not under direct neural control, as has previously been thought. The few nerves that are present are connected to blood vessels, not to gland cells. Thanks to the secretion of the correct amount of insulin and other hormones, the body is able to maintain an almost constant level of blood sugar.

Babies tune in to human voices even when asleep
Babies tune in to human voices even when asleep
In a study published in the journal Current Biology, researchers from Institute of Psychiatry (IoP) King's College London have found that babies as young as three months are able to tune in to the sound of our voices and perceive different emotions, even when they are asleep. Using functional magnetic resonance imaging (fMRI), researchers took brain images of sleeping babies and discovered that special areas in the brain which process sound are more sensitive than previously thought.

MicroRNAs in the songbird brain respond to new songs
CHAMPAIGN, lll. Whenever it hears an unfamiliar song from a male of the same species, the zebra finch stops chirping, hopping and grooming. It listens attentively for minutes at a time, occasionally cocking its head but otherwise immobile. Once it becomes familiar with the song, it goes back to its busy routine.

TV food advertising increases children’s preference for unhealthy foods
Researchers at the University of Liverpool have found that children who watch adverts for unhealthy food on television are more likely to want to eat high-fat and high-sugar foods. The study by researchers in the Institute of Psychology, Health and Society examined the food preferences of a group of 281 children aged six to 13 years old from the North West of England.

Farm animal disease to increase with climate change
Scientists at the University of Liverpool have shown that recent climate change could have caused a serious infectious disease in farm animals to spread through Europe. Researchers looked at changes in the behaviour of bluetongue - a viral disease of cattle and sheep – from the 1960s to the present day, as well as what could happen to the transmission of the virus 40 years into the future.

Breakthrough treatment for hurting horses
Breakthrough treatment for hurting horses
A new osteoarthritis drug combination trialled by University of Sydney researchers could significantly extend the working life of racing and other performance horses and could potentially benefit humans. Various medications have been assessed for the treatment of osteoarthritis in horses, but this is one of the first studies to show a new drug combination has the ability to slow down damage to joints, rather than just alleviate pain.

Preventing diabetes damage: Zinc’s effects on a kinky, two-faced cohort
ANN ARBOR, Mich.—In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving. Recent research at the University of Michigan offers new details about how zinc performs this "security guard" function.

Supplement burns muscle fat, improves exercise performance
Supplement burns muscle fat, improves exercise performance
A new study has shown for the first time that taking a particular food supplement increases muscle carnitine content and reduces muscle carbohydrate use, while increasing fat used for energy production during exercise. Researchers at The University of Nottingham's School of Biomedical Sciences found that recreational athletes who took a dietary supplement containing L-carnitine — a nutrient found in common food sources — combined with carbohydrates showed several metabolism benefits during low- and high-intensity exercise and improved exercise performance.
