But unsteadiness on the feet, a tendency to fall over, and losing the ability to steer is considerably more of a problem when life is normally spent in trees or in the air.

The authors from the Animal Health and Veterinary Laboratories Agency (AHVLA) reveal how they were called to a primary school in Cumbria last summer after the bodies of 12 young blackbirds were found.

A further blackbird was discovered alive, but obviously "unwell." And two more dead birds were subsequently found.

Richmond, Va. – (November 1, 2012) – Men with employment-contingent health insurance (ECHI) who suffer a health shock, such as a cancer diagnosis or hospitalization, are more likely to feel "locked" into remaining at work and are at greater risk for losing their insurance during this critical time as compared to men who are on their spouse's insurance plan or on private insurance plans, according to a new study by Virginia Commonwealth University Massey Cancer Center.

New studies support limiting daily sodium consumption to less than 1,500 milligrams, according to a new American Heart Association presidential advisory.

The advisory, published in the American Heart Association's journal Circulation, is based on a thorough review of recent laboratory, animal, observational and clinical studies that reaffirm the association's 2011 advisory that limiting sodium (salt) to less than 1,500 mg per day is linked to a decreased risk of high blood pressure and cardiovascular disease, including stroke.

Boulder, CO, USA – In the evolutionary long run, small critters tend to evolve into bigger beasts -- at least according to the idea attributed to paleontologist Edward Cope, now known as Cope's Rule. Using the latest advanced statistical modeling methods, a new test of this rule as it applies dinosaurs shows that Cope was right -- sometimes.

A person doesn't have to go far to find a polycyclic aromatic hydrocarbon (PAH). These carcinogen precursors are inhaled through automobiles exhaust during the morning commute, are present in a drag of cigarette smoke, and are part of any barbequed meal.

With active surveillance many men with prostate cancer could dispense with radiation treatment and surgery, and thus avoid adverse effects such as incontinence and impotence. This is the outcome of a study of almost 1,000 men diagnosed with prostate cancer conducted at Sahlgrenska Academy, University of Gothenburg, Sweden.

Couples about to tie the knot shouldn't ignore nagging doubts about getting married, warns a University of Alberta researcher.

"If you are having doubts about the relationship, just ignoring them may make a difference years down the road," said Matthew Johnson who co-authored the study while at Kansas State University. Johnson is now an assistant professor in the University of Alberta Department of Human Ecology.

Bariatric surgery, which significantly curtails the amount of food a person can eat, is the most effective treatment against obesity and is being recognized as a potentially valuable tool in the fight against diabetes related to obesity. It is being performed on increasing numbers of people worldwide, including teenagers.

CINCINNATI—A University of Cincinnati (UC) cancer biology team reports breakthrough findings about specific cellular mechanisms that may help overcome endocrine (hormone) therapy-resistance in patients with estrogen-positive breast cancers, combating a widespread problem in effective medical management of the disease.

Infant mortality has fallen by half, and the number of women who died from complications during pregnancy and childbirth by three-quarters. This is the result of a four-year health care project in one of India's poorest districts.

"We're overjoyed that mortality could be reduced with relatively simple means like mobile health care centres. It was successful because pregnant women and new mothers got the opportunity to actively seek care."

NEW YORK (Nov. 01, 2012) -- Weill Cornell Medical College announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation. Researchers at Weill Cornell have been awarded three research grants totaling more than $1.5 million. Weill Cornell's Dr. Juan R. Cubillos-Ruiz, a postdoctoral research associate in medicine in the laboratory of Dean Dr. Laurie H. Glimcher, will pursue an innovative global health and development research project titled, "Tailored Nanodevices to Understand Resistance Against HIV," Dr.

Testing women to see if they are cured of HPV (the virus that can cause genital warts and cervical cancer) following treatment for abnormal cells on the surface of the cervix is more effective and cheaper than cytology testing (cervical screening) alone, suggests a study published on bmj.com today.A second study published today, finds that the risk of cervical cancer after treatment and cytological follow-up for abnormalities remains about four times higher than in women with normal cytology tests, regardless of age and stage o

Trust between partners is a fundamental requisite in agricultural biotech projects, according to Canadian researchers who today published insights from a four year study into what built or undermined trust in eight African case studies.

In a special supplement published in the UK-based journal Agriculture and Food Security, the research team from the Sandra Rotman Centre at the University Health Network and the University of Toronto, concluded trust within such projects has six key determinants: honesty, transparency, capability, accountability, solidarity and generosity.

KNOXVILLE – When foot-and-mouth disease swept through the British countryside in early 2001, more than 10 million sheep, cattle and pigs were slaughtered to control the disease. Despite the devastation, the disease was contained within ten months in part owing to the availability in that country of finely detailed farm data, which enabled mathematical modelers to make accurate predictions about the spread of the disease and suggest optimal ways of managing it.

For many American teens, the road to college goes through the chapel.

Sociologists from Brigham Young University and Rice University found religiously-affiliated youth are 40 percent more likely to graduate high school than their unaffiliated peers and 70 percent more likely to enroll in college.

The researchers note that teens' fellow church-goers are an important factor, serving as mentors who help teens set their sights high.
