CT scanning used to uncover remnants of malignancy hidden inside medieval bones provides new insight into cancer prevalence in a pre-industrial world.
A new study shows growing evidence that Pennsylvania's 500 ft. unconventional natural gas (UNG) well setback distance may not be protective against routine exposures to toxic substances such as benzene, hydrogen sulfide, carbon disulfide and PM2.5. This is the first study to assess the effectiveness of setback regulations for UNG development, and the findings suggest that protectiveness of setback policies also depends upon opportunities for exemptions from these siting restrictions.
A new study, conducted by three UC Davis Comprehensive Cancer Center researchers, studies young adult smoking trends three years after the start of California's law raising the sales age of tobacco to 21.
Efforts to prevent human exposure to asbestos may be mobilizing the cancer-causing mineral so that it can reach water supplies, based on new findings about how the fibers move through soil.
Genetically engineered animals provide important insights into the molecular basis of health and disease. Research has focused mainly on genetically modified mice, although other species, such as pigs, are more similar to human physiology. Researchers at the Technical University of Munich (TUM) have now generated chickens and pigs in which target genes in desired organs can be efficiently altered.
Investigators at Wake Forest School of Medicine, part of Wake Forest Baptist Health, have identified a set of new genetic markers that could potentially lead to new personalized treatments for lung cancer.
Researchers from the group of Hans Clevers developed the first patient-derived organoid model for cervical cancer. They also modelled the healthy human cervix using organoids. The researchers used the platform to study sexually transmitted infections for a herpes virus. The model can potentially also be used to study human papillomavirus (HPV), which is one of the main causes of cervical cancer. The results will be published in Cell Stem Cell on the 13th of April, 2021.
E-cigarettes that deliver a cigarette-like amount of nicotine are associated with reduced smoking and reduced exposure to the major tobacco-related pulmonary carcinogen, NNAL, even with concurrent smoking, according to a new study led by researchers at Virginia Commonwealth University and Penn State College of Medicine in Hershey, Pennsylvania
Peer reviewed and published in the journal Mutagenesis, results show that under the conditions of test, undiluted vape e-liquids and their aerosol extracts exhibited entirely absent or vastly reduced indications of DNA damaging potential in cells, compared to smoke from combustible cigarettes. Imperial scientists are the first to publish results using the ToxTracker cell assay system for the assessment of vape e-liquids and aerosols.
More than 60% of U.S. adults who vape are interested in quitting. Among those who vape to help them to quit smoking, some are successful while others continue smoking and using electronic cigarettes.
