People who frequently use tanning beds may be spurred by an addictive neurological reward-and-reinforcement trigger, researchers at UT Southwestern Medical Center have found in a pilot study.
This could explain why some people continue to use tanning beds despite the increased risk of developing melanoma, the most lethal form of skin cancer. The brain activity and corresponding blood flow tracked by UT Southwestern scientists involved in the study is similar to that seen in people addicted to drugs and alcohol.
“Using tanning beds has rewarding effects in the brain so people may feel compelled to persist in the behavior even though it’s bad for them,” said Dr. Bryon Adinoff, professor of psychiatry and senior author of the study available online and in a future print edition of Addiction Biology. “The implication is, ‘If it’s rewarding, then could it also be addictive?’ It’s an important question in the field.”
About 120,000 new cases of melanoma are diagnosed in the U.S. each year, according to the Skin Cancer Foundation. People younger than 30 who use a tanning bed 10 times a year have eight times the risk of developing malignant melanoma. While public knowledge of these dangers has grown, so has the regular use of tanning beds.
In this study, participants used tanning beds on two separate occasions: one time they were exposed to ultraviolet radiation and another time special filters blocked exposure to ultraviolet radiation. Participants did not know on which session they received the real or the filtered ultraviolet exposure. At each visit, participants were asked before and after each session how much they felt like tanning. Participants were also administered a compound that allowed scientists to measure brain blood flow while they were tanning.
Dr. Adinoff, who also is a staff physician at the Veterans Affairs North Texas Health Care System, said the next step is to create technology to further study brain changes among frequent tanners.
Other UT Southwestern researchers involved in the study were Dr. Heidi Jacobe, assistant professor of dermatology; Dr. Michael Devous, professor of radiology; and Thomas Harris, senior research scientist. Former dermatology resident Dr. Cynthia Harrington served as lead author.
The study was funded by the Department of Dermatology at UT Southwestern. Dr. Steven Feldman of Wake Forest University donated the ultraviolet radiation filters used in the tanning bed, and GE Healthcare donated the radioligand, the compound that traced the brain changes.

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...
