A new temporary "electronic tattoo" developed by Tel Aviv University that can measure the activity of muscle and nerve cells researchers is poised to revolutionize medicine, rehabilitation, and even business and marketing research.
The tattoo consists of a carbon electrode, an adhesive surface that attaches to the skin, and a nanotechnology-based conductive polymer coating that enhances the electrode's performance. It records a strong, steady signal for hours on end without irritating the skin.
How much marijuana does the average joint contain?
"It seems like an odd question but major policy questions depend on the answer," said Greg Ridgeway, an associate professor of criminology and statistics at the University of Pennsylvania.
Until now, there's been no consensus. Previous research suggested a single joint held anywhere from 0.3 to 0.75 grams of cannabis, with some users reporting amounts as high as 1 gram. The United States Office of National Drug Control Policy used 0.5 grams as its baseline.
What could be the downside to unemployment rates plummeting in recent years? One place to look is the road.
Research has shown that when the economy improves, motor vehicle fatalities also increase.
According to new findings from Monica He, a demography doctoral candidate at the University of Pennsylvania, the driving force behind this link during the recent Great Recession was higher deadly crashes involving large, commercial trucks. She published her findings in the journal Social Science & Medicine.
COLORADO SPRINGS, CO - Sustaining a concussion during adolescence may be more common than previous estimates, according to researchers presenting their study at the American Orhopaedic Society for Sports Medicine's Annual Meeting in Colorado Springs, CO today.
COLORADO SPRINGS, CO - Creating a program to prevent hamstring injuries in minor league and major league baseball players might be a possibility say researchers presenting their work today at the American Orthopaedic Society of Sports Medicine's (AOSSM) Annual Meeting in Colorado Springs, CO.
"Hamstring injuries, both acute and chronic are on the rise in baseball and injury prevention programs may help stem this trend," says lead author, Holly Silvers-Granelli, MPT, PhD Candidate at the University of Delaware in Newark, Delaware.
London's Great Smog of 1952 resulted in thousands of premature deaths and even more people becoming ill. The five December days the smog lasted may have also resulted in thousands more cases of childhood and adult asthma. Researchers from Columbia University's Mailman School of Public Health, the University of California, San Diego and University of Massachusetts studied how London's Great Smog affected early childhood health and the long-term health consequences.
CINCINNATI - A new online open-access database has been developed by scientists to allow the clinical responses of more than 5 million patients to all FDA-approved drugs to be used to identify unexpected clinical harm, benefits and alternative treatment choices for individual patients, according to a study appearing July 8 in Nature Biotechnology.
Discounts tied to buying large quantities of virtual goods have little impact on profitability and do not increase the number of customers making purchases, according to economists at the University of Chicago.
The findings come from a field experiment of more than 14 million players of mobile games by King Digital Entertainment, maker of Candy Crush Saga. For the study, researchers offered a range of quantity discounts on virtual goods, which players buy for use within a video game.
An international team of researchers has developed a website at d-place.org to help answer long-standing questions about the forces that shaped human cultural diversity.
COLORADO SPRINGS, CO - For athletes and highly active patients who sustain cartilage injuries to their knee, an osteochondral allograft transplantation can be a successful treatment option, according to research presented today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Annual Meeting in Colorado Springs, CO. The study showed these patients were consistently able to return to sport or recreational activities after the surgery, though frequently at a lower activity level.
Florence, Italy - 9 July 2016: Immunotherapy reduces cardiovascular risk in patients with rheumatoid arthritis, according to research presented today at Frontiers in CardioVascular Biology (FCVB) 2016 by Professor Aida Babaeva, head of the Department of Internal Medicine, Volgograd State Medical University, Volgograd, Russia.1 The combination of two extra-low dose anticytokine drugs reduced rheumatoid arthritis disease activity and cardiovascular events.
The United States is on course to experience a steep drop in the number of stem cell researchers in coming years as a large portion of academic scientists reach retirement age and younger scientists continue to leave academia for jobs in industry.
The trend is called the "graying of the biomedical workforce," and many suspect that a preference for older, more experienced researchers in the competitive government grant application process is driving younger scientists away from academia.
In a study published online by JAMA Ophthalmology, Gwyneth Rees, Ph.D., of the University of Melbourne, Australia, and colleagues examined the association between severity of diabetic retinopathy and diabetic macular edema with symptoms of depression and anxiety in adults with diabetes.
Group A streptococcus (GAS) can cause a life-threatening necrotizing fasciitis, which spreads rapidly and destroys soft tissue. Treatment of these GAS necrotizing soft tissue infections (NSTI) typically requires intensive care along with surgical intervention and often amputation of the affected limb. A new study in JCI Insight provides evidence that formation of biofilm, a collection of bacteria that adhere to a tissue surface, can be a complicating feature of GAS NSTI.
