Millions of patients with advanced disease in palliative care settings receive oxygen therapy to help them breathe more easily. But a new study says roughly half of them don't benefit from the intervention, and among those who do benefit, it doesn't make a bit of difference whether they get pure oxygen or just plain old room air -- both offer equal benefit.

Computer technique could help partially sighted 'see' better

Thousands of people who are partially sighted following stroke or brain injury could gain greater independence from a simple, cheap and accessible training course which could eventually be delivered from their mobile phones or hand-held games consoles, according to a new study.

More people are likely to believe scientific studies claiming that oil drilling is riskier, not safer, than was previously thought, according to a new study of attitudes in California. What's more the findings show that scientists' efforts to influence public opinion have a limited effect.

Computer models suggest treatments for fractures that won't heal

03:01 03-09-2010; source: www.sciencedaily.com

New models, reinforced by in vivo experimentation, show why 5-10 percent of bone fractures don't heal properly, and how these cases may be treated to restart the healing process. Results of the model may benefit the aging population in which the occurrence of bone fractures is expected to rise substantially in the near future.

Cigarette smoke may contribute to lung inflammation through a new chemical pathway

03:01 03-09-2010; source: www.sciencedaily.com

Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to new findings. Researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation.
