Smoking ban dramatically reduces air pollution in Irish pubs

...tests also demonstrated an 83 percent reduction in tiny particulate matter in bar air. "These results confirm that the approach of a total ban on smoking in the workplace is successful in reducing the exposure of workers to particles," said Dr. Clancy. "We have previously shown that a reduction of parti...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...culture systems to grow vaccines using viruses as tiny factories to churn out mass amounts of vaccines is a growing business. A similar technology using human cell lines is used to produce the hepatitis B vaccine, while one form of a vaccine against human papilloma virus is made using the same insect ce...

Fragile X, Down syndromes linked to faulty brain communication

...were surprised to find that Stardust had collected tiny grains of the mineral osbornite, which chemically is titanium nitride. Osbornite forms only at ultra-hot temperatures of about 3,140 Fahrenheit. Scientists thus concluded that the osbornite could have formed near the sun, and ejected to the outer rea...

A new, nanoporous ceramic filter offers hope to kidney-dialysis patients

... units. Each nephron in turn contains a cluster of tiny blood vessels called a glomerulus, which is attached to a tubule. Every 24 hours, the kidneys filter about 200 quarts of fluid, returning 198 quarts of purified fluid to the bloodstream and excreting 2 quarts in the form of urine. The toxins remove...

Mayo Clinic study shows drug-eluting stent use in heart patients determined more by insurance type

About Stents Stents are tiny mesh tubes that are threaded through a vessel to reach a blocked blood vessel and prop it open -- thus restoring and maintaining blood flow to the heart. Bare-metal stents have been widely and successfully used for more than a decade, though they are...

Moreover, these cells appear to be highly sensitive to the tumor-promoting properties of TGFb and thereby manifest a more aggressive behavior. "Wit...

Insight on fruit fly immune system could lead to new types of vaccines, Stanford researchers say

STANFORD, Calif. - The tiny fruit fly has a lot to teach humans. Researchers at the Stanford University School of Medicine have found for the first time that flies' primitive immune systems may develop long-term protection from infection, an ability previously thought impossibl...

Holographic images use shimmer to show cellular response to anticancer drug
