BOZEMAN, Mont. – In the same week that the U.S. surgeon general issued a 101-page report about the dangers of skin cancer, researchers at Montana State University published a paper breaking new ground on how DNA – the genetic code in every cell – responds when exposed to ultraviolet (UV) light.
The findings advance fundamental understanding of DNA damage by the UV rays found in sunlight. This damage can lead to skin cancer, aging and some degenerative eye diseases.
Researchers at the MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects — no glasses (or contact lenses) required.
The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on, or electronic readers that eliminate the need for reading glasses, among other applications.
As much as social equality is advocated in the United States, a new study suggests that besides evaluating their own race and religion most favorably, people share implicit hierarchies for racial, religious, and age groups that may be different from their conscious, explicit attitudes and values.
The study findings appear in Psychological Science, a journal of the Association for Psychological Science.
Most people are familiar with Hibiscus flowers- they are an iconic symbol of tropical resorts worldwide where they are commonly planted in the landscape. Some, like Hawaii's State Flower- Hibiscus brackenridgei- are endangered species.
Only a relatively few botanists and Hawaiian conservation workers, however, are aware of an equally beautiful and intriguing related group of plants known as Hibiscadelphus- literally "brother of Hibiscus".
Researchers at the University of California, Los Angeles and the Chinese Academy of Sciences have pioneered a new study that could greatly improve current methods of localising birdsong data. Their findings, which ascertain the validity of using statistical algorithms to detect multiple-source signals in real time and in three-dimensional space, are of especial significance to modern warfare.
White, brown and beige adipocytes, or fat cells, are inherently different. Each of these cell types has different functions and each plays its own role in metabolism. In the human body, white adipose tissue is by far the most prevalent. Its primary function is energy storage. On the other hand, brown adipocytes utilize available energy to generate heat but are only found in a few places in the adult human body.
Functional group transformations are central to organic synthesis. Traditionally, the functionalities used in such transformations are highly active organic groups such as halogens, ester groups and hydroxyl groups.
There's a good reason people over 60 are not donor candidates for bone marrow transplantation. The immune system ages and weakens with time, making the elderly prone to life-threatening infection and other maladies, and a UC San Francisco research team now has discovered a reason why.
There have been several news reports that the world's first dengue vaccine will be available next year. However, the latest clinical trials show that the vaccine only provides a protection of around 50 per cent for DENV-2 and DENV-1, which are commonly found in Singapore.
Going to the dentist isn't fun for anyone, but for those with periodontal disease related to type 2 diabetes, a new research discovery may have them smiling. In a report appearing in the August 2014 issue of the Journal of Leukocyte Biology, one of the most important blood cells involved in the human immune response, B cells, are shown to promote inflammation and bone loss in type 2 diabetes-associated periodontal disease.
The human body contains a unique protein that has the unusual property of destroying itself after a few hours of existence - it must therefore be continually recreated and is no stable protein. The protein, called PAI-1, affects many physiological functions, including the dissolving of coagulated blood. If you get a blood clot, it is due to the fact that the a clot has accumulated in a blood vessel, and therefore PAI-1 is extremely important – for the human body's survival in general and for helping people with a blood clot or other blood diseases in which coagulation plays a role.
New Orleans, LA – Dr. Oren Tessler, Assistant Professor of Clinical Surgery at LSU Health Sciences Center New Orleans School of Medicine, is part of a team of plastic and reconstructive surgeons who report a high success rate using a method to screen and select patients for a specific surgical migraine treatment technique. More than 90% of the patients who underwent this surgery to decompress the nerves that trigger migraines experienced relief and also got a bonus cosmetic eyelid surgery.
Los Angeles, CA (August 1, 2014) While it is known that members of the U.S. military overall are more likely to use alcohol, a new study finds that female enlistees and female veterans are actually less likely to drink than their civilian counterparts. This study was published today in Armed Forces & Society, a SAGE journal published on behalf of the Inter-University Seminar on Armed Forces and Society.
ANN ARBOR—Imagine you're fighting for your life but no matter how hard you hit, your opponent won't go down.
The same can be said of highly treatment-resistant cancers, such as head and neck cancer, where during radiation and chemotherapy some cancer cells repair themselves, survive and thrive. Head and neck cancer is the sixth most common cancer in the world, but the late detection and treatment resistance result in a high mortality rate.
While previous studies have shown that marine noise can affect animal movement and communication, with unknown ecological consequences, scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have demonstrated that boat noise stops embryonic development and increases larval mortality in sea hares.
