Boys may be more apt than girls to have childhood asthma, but, when compared to girls, they are also more likely to grow out of it in adolescence and have a decreased incidence of asthma in the post-pubertal years.

Prions, the pathogens that cause scrapie in sheep, can survive in the ground for several years, as researchers have discovered. Animals can become infected via contaminated pastures. It is not yet known whether the pathogens that cause BSE and CWD are equally resistant.

A possible future way to prevent relapses into drug dependence has been discovered. The target is the dopamine-producing nerve cells in the midbrain.

A virus that commonly infects potatoes bears a striking resemblance to one of the key proteins implicated in Alzheimer's disease, and researchers have used that to develop antibodies that may slow or prevent the onset of AD.

The NHS and private health care are not providing good enough basic care to a large portion of the population in England, especially older and frailer people, according to a new study. Overall, only 62 percent of the care recommended for older adults is actually received, conclude the authors.

A study in the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery. Results of this study suggest that it is the severity of the condition, rather than a patient's presurgical weight, that determines if OSA will be resolved.

Synthetic Biology is bearing fruit: the tuberculosis pathogen can be fooled by a widely used food additive. The WHO records around nine million new cases of the disease each year, and about 50 million people are infected with a strain of Mycobacterium tuberculosis that is resistant to the antibiotics Isoniazid and Rifampicin.

For the first time, a drug therapy appears to reduce lung function loss in patients with moderate to severe chronic obstructive pulmonary disease, according to the results of a randomized, double-blind, placebo-controlled trial in 42 countries.

A growing body of research suggests that there is a potent way to fight symptoms of depression that doesn't involve getting a prescription. This potent weapon? Hope. "We're finding that hope is consistently associated with fewer symptoms of depression. And the good news is that hope is something that can be taught, and can be developed in many of the people who need it," said Jennifer Cheavens at Ohio State University.
