Exposure to secondhand cigarette smoke increases the risk of developing cervical tumors, according to researchers at the Johns Hopkins Bloomberg School of Public Health and School of Medicine. The researchers’ results also corroborated past studies that found an association between active cigarette smoking and cervical neoplasia—the growth of a tumor. The concept of the Hopkins study was the result of collaboration between several researchers supported by the Maryland Cigarette Restitution Fund. The study is published in the January 2005 issue of Obstetrics & Gynecology.
“An association between active cigarette smoking and cervical cancer has been noted in numerous studies, but less is known about the potential link between passive smoking and the development of cervical neoplasia. When these new data for cervical cancer are considered in light of similar results from previously published studies, our findings suggest that passive smoking may be firmly linked with cervical cancer,” said Anthony J. Alberg, PhD, MPH, senior author of the study and an assistant professor in the Bloomberg School of Public Health’s Department of Epidemiology. “Our study of two large cohorts found that women who lived with smokers had a 40 percent or greater risk of developing cervical neoplasia.”
The Hopkins researchers examined the personal cigarette smoking and household passive smoking exposures of two Washington County, Md. , cohort groups in 1963 and 1975. Questionnaires from the two groups, which totaled 51,173 women, were compared to the Washington County cancer registry. The researchers found a stronger association between passive smoking and an increased risk for developing cervical neoplasia in the earlier cohort study—a 2.1-fold increased risk of cervical neoplasia in 1963 and a 1.4-fold increased risk in 1975.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
