Participants who quit had a 46% lower death rate
In a new study of 5,887 middle-aged smokers with mild lung disease, those who were randomly assigned to a quit-smoking program had a lower death rate than those assigned to usual care, even though only 21.7 percent of them actually quit smoking.
The annual death rates were 8.8 per 1000 participants in the quit-smoking program and 10.4 per 1000 in the usual care group. The annual death rates for those who actually quit was even more positive: 6.0 per 1000 patients compared with 11.0 per 1000 in those who did not quit smoking. Overall, the death rate of those in both groups who were able to quit smoking was 46 percent lower than those who did not quit.
The study, "The Effects of a Smoking Cessation Intervention on 14.5-year Morality," is the first experimental study to show that stopping smoking adds years to life. It is published in the Feb. 15, 2005, issue of Annals of Internal Medicine. The findings were based on data from the Lung Health Study. Randomized trials like the Lung Health Study are widely regarded as the gold standard for proof among clinical studies. "We know that people who smoke should quit smoking," said one of the study authors, John E. Connett, PhD, professor of biostatistics of the University of Minnesota School of Public Health. "This study showed that with very simple lung function tests -- spirometry -- we can find people who can benefit the most from an intensive quit-smoking program," Connet said. "And it not only made them healthier and feel better, it caused substantial reductions in death rate."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
