A new study from Minnesota finds the incidence of nonmelanoma skin cancer increasing among men and women under the age of 40, according to an article in the August 10 issue of JAMA.
The overall incidence of nonmelanoma skin cancer, consisting of squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), is increasing, according to background information in the article. This increasing incidence is most likely due to a combination of factors, including increased exposure to UV light, ozone depletion, and increased surveillance. Long-term exposure to the sun resulting in photodamage is perhaps the biggest risk factor for nonmelanoma skin cancer. In the United States, approximately 800,000 new cases of BCC and 200,000 new cases of SCC were diagnosed in 2000. Nonmelanoma skin cancer generally occurs in persons older than 50 years, and in this age group, its incidence is increasing rapidly. However, little is known about its incidence in persons younger than 40 years.
Leslie J. Christenson, M.D., of Mayo Clinic, Rochester, Minn., and colleagues conducted a study to estimate the sex- and age-specific incidence of BCC and SCC in Olmsted County, Minnesota, in a young population (less than 40 years old) from the beginning of 1976 through 2003. The patients in this study have comprehensive medical records captured through the Rochester Epidemiology Project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
