Image transport through new fiber architecture rivals that of current endoscopy imaging fibers
Date: Feb-27-2014After having recently discovered a new way to propagate multiple beams of light through a single strand of optical fiber, engineers at the University of Wisconsin-Milwaukee (UWM) now have found that their novel fiber architecture can transmit images with a quality that is comparable or better than the current commercial endoscopy imaging fibers.Because of this, the work has potential not only in next-generation high-speed communication, but also biomedical imaging.The work is published in the journal Nature Communications.
10 percent of non-lifetime marijuana users would try marijuana if legal
Date: Feb-27-2014National support for marijuana ("cannabis") legalization is increasing in the United States (US). Recreational use was recently legalized in the states of Colorado and Washington; other states across the country are expected to follow suit. To date, an additional 15 states have decriminalized marijuana use, and 19 states and the District of Columbia now allow medical marijuana to be prescribed.
Can babies learn to read?
Date: Feb-27-2014Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found.
In mouse model of melanoma, nanoparticles and magnetic fields train immune cells to fight cancer
Date: Feb-27-2014Using tiny particles designed to target cancer-fighting immune cells, Johns Hopkins researchers have trained the immune systems of mice to fight melanoma, a deadly skin cancer. The experiments, described on the website of ACS Nano, represent a significant step toward using nanoparticles and magnetism to treat a variety of conditions, the researchers say."Size was key to this experiment," says Jonathan Schneck, M.D., Ph.D., a professor of pathology, medicine and oncology at the Johns Hopkins University School of Medicine's Institute for Cell Engineering.
Post-code lottery for hip replacement surgery reduced by NHS Scotland
Date: Feb-27-2014A reduction in the post-code lottery for hip replacement surgery has been achieved in Scotland without recourse to the private sector, according to new research published in the Journal of the Royal Society of Medicine.
NIST consortium partners answer the question: 'How well did you sequence that genome?'
Date: Feb-27-2014In December 2013, the U.S. Food and Drug Administration approved the first high-throughput DNA sequencer (also known commonly as a "gene sequencer"), an instrument that allows laboratories to quickly and efficiently sequence a person's DNA for genetic testing, medical diagnoses and perhaps one day, customized drug therapies. Helping get the new device approved was another first: the initial use of a reference set of standard genotypes, or "coded blueprints" of a person's genetic traits.

Why almost winning is just as good for some gamblers
Date: Feb-27-2014A new study led by the University of Exeter and Swansea University has pinpointed the changes in the brain that lead gamblers to react in the same way to near-misses as they do to winning.The research shows that near-misses are underpinned by increases in the brain's electrical activity, particularly in the theta frequency range - known to be involved in processing win and loss outcomes.They found that these increases in theta are linked to both how severe someone's gambling history is and how susceptible they might be to developing a future gambling problem.
Stigma is the main barrier to accessing mental health care
Date: Feb-27-2014Mental health stigma is a key factor preventing people from accessing the care they need, according to new research from King's College London.The new study, published in Psychological Medicine, brings together data from 144 studies, including over 90,000 participants worldwide.Approximately 1 in 4 people have a mental health problem, yet in Europe and the US, up to 75 percent of people with mental health disorders do not receive treatment.
Diabetic foot ulcers healed, amputation prevented by tissue repair drug
Date: Feb-27-2014Patients were twice as likely to have a diabetic foot ulcer heal within eight weeks when they were treated with a tissue repair drug versus a placebo, according to new research accepted for publication in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).Foot ulcers are a common complication from diabetes than can lead to hospitalization and lower limb amputation. In 2006, about 65,700 non-traumatic lower-limb amputations were performed in people with diabetes, according to the Centers for Disease Control and Prevention.
