'Wonder material' graphene could revolutionize cell phones, solar panels and more

New American Chemical Society video

2012-10-09
(Press-News.org) WASHINGTON, October 8, 2012 — Smart phones almost as thin and flexible as paper and virtually unbreakable. Solar panels molded to cover the surface of an electric or hybrid car. Possible treatments for damaged spinal cords. It's not science fiction. Those all are possible applications of a material known as graphene. This so-called "wonder material," the world's strongest (100 times stronger than steel) and thinnest (one ounce would cover 28 football fields), is the focus of a new episode of the ChemMatters video series. The video is at www.BytesizeScience.com.

The video, from the award-winning Digital Services Unit in the American Chemical Society (ACS) Office of Public Affairs, explains how graphene's incredible properties originate from the unique arrangement of its atoms. ACS is the world's largest scientific society.

Like diamonds and coal, graphene is made up entirely of carbon. But unlike those materials, graphene's carbon atoms are arranged in two-dimensional sheets, making it incredibly strong and flexible. Since graphene also conducts electricity as well as copper, it could lead to flexible cell phone touchscreens and transparent, inexpensive solar cells. Ongoing advances in manufacturing graphene are bringing these and other devices closer to reality.

### The video is based on an article in the latest issue of ChemMatters, ACS' quarterly magazine for high school students, and was produced by the team behind ACS' award-winning Bytesize Science videos.

ChemMatters has been connecting chemistry to our everyday lives for the past 28 years. Published quarterly by the ACS Office of High School Chemistry, each issue contains articles about the chemistry of everyday life and is of interest to high school students and their teachers.

A DNA-made trap may explain amyloidosis aggravation

2012-10-09
Rio de Janeiro, Brazil- Amyloidosis is a group of clinical syndromes characterized by deposits of amyloid fibrils throughout the body. These fibrils are formed by aggregates of proteins that have not been properly folded. Deposits of amyloid fibrils are found in a number of diseases, including Alzheimer's and Parkinson's diseases and type-2 diabetes. The amyloid deposits can be localized, as in the brain of Alzheimer's patients, or found spread through the body, as in amyloidosis related to mutations in the transthyretin gene. The clinical meaning of amyloid deposits ...

Child-free women feel intense pressure to have kids -- but rarely stress over it

2012-10-09
Women who choose to be permanently childfree perceive more social pressures to become mothers than other women, but feel less distress about not having kids than women who are childless from infertility or other reasons, a new national study shows. The study, from a national survey of nearly 1,200 American women of reproductive age with no children, identified various reasons why women have no children, from medical and situational barriers to delaying pregnancy to choosing to be childfree. It sought to determine if those reasons contributed to different types of concerns ...

Caffeine may block inflammation linked to mild cognitive impairment

2012-10-09
URBANA – Recent studies have linked caffeine consumption to a reduced risk of Alzheimer's disease, and a new University of Illinois study may be able to explain how this happens. "We have discovered a novel signal that activates the brain-based inflammation associated with neurodegenerative diseases, and caffeine appears to block its activity. This discovery may eventually lead to drugs that could reverse or inhibit mild cognitive impairment," said Gregory Freund, a professor in the U of I's College of Medicine and a member of the U of I's Division of Nutritional Sciences. Freund's ...

New link between high-fat 'Western' diet and atherosclerosis identified

2012-10-09
New York, NY (October 8, 2012) — Columbia University Medical Center (CUMC) researchers have found that a diet high in saturated fat raises levels of endothelial lipase (EL), an enzyme associated with the development of atherosclerosis, and, conversely, that a diet high in omega-3 polyunsaturated fat lowers levels of this enzyme. The findings establish a "new" link between diet and atherosclerosis and suggest a novel way to prevent cardiovascular heart disease. In addition, the research may help to explain why the type 2 diabetes drug rosiglitazone (Avandia) has been linked ...

Researchers discover regenerated lizard tails are different from originals

Researchers discover regenerated lizard tails are different from originals
2012-10-09
TEMPE, Ariz. - Just because a lizard can grow back its tail, doesn't mean it will be exactly the same. A multidisciplinary team of scientists from Arizona State University and the University of Arizona examined the anatomical and microscopic make-up of regenerated lizard tails and discovered that the new tails are quite different from the original ones. The findings are published in a pair of articles featured in a special October edition of the journal, The Anatomical Record. "The regenerated lizard tail is not perfect replica," said Rebecca Fisher, an associate professor ...

Hospital rankings dramatically affected by calculation methods for readmissions and early deaths

2012-10-09
Hospital readmission rates and early death rates are used to rank hospital performance but there can be significant variation in their values, depending on how they are calculated, according to a new study in CMAJ (Canadian Medical Association Journal). "Hospital-specific readmission rates have been reported as a quality of care indicator but no consensus exists on how these should be calculated. Our results highlight that caution is required when comparing hospital performance based on 30-day or urgent readmissions given their notable variation when methods used in their ...

Canadian C-spine rule more accurate in diagnosing important cervical spine injuries than other rules

2012-10-09
To screen for cervical spine injuries such as fractures in the emergency department, the Canadian C-spine rule appears to be more accurate compared with NEXUS, another commonly used rule, according to a study in CMAJ (Canadian Medical Association Journal). NEXUS stands for the National Emergency X-Radiography Utilization Study. "In the only direct comparison, the Canadian C-spine rule appeared to have better diagnostic accuracy, and it should be used over NEXUS to assess the need for cervical spine imaging," writes Dr. Chris Maher, Director, Musculoskeletal Division, ...

Moffitt researchers study effect of chemotherapy combined with immunotherapy for advanced cancers

2012-10-09
Researchers at Moffitt Cancer Center and colleagues at the University of South Florida and Tianjin Medical University Cancer Institute and Hospital in China have discovered that combining chemotherapy drugs and immunotherapy cancer vaccines results in an enhanced anti-tumor effect. The results, achieved by testing cancer cells in a laboratory, are surprising because chemotherapy generally reduces immunity and could cancel out the benefits of immunotherapy when given together. Their study appears in the Aug. 31 online issue of Cancer Research, a publication of the American ...

Recovering 'bodyguard' cells in pancreas may restore insulin production in diabetics

2012-10-09
PHILADELPHIA—The key to restoring production of insulin in type I diabetic patients, previously known as juvenile diabetes, may be in recovering the population of protective cells known T regulatory cells in the lymph nodes at the "gates" of the pancreas, a new preclinical study published online October 8 in Cellular & Molecular Immunology by researchers in the Department of Bioscience Technologies at Thomas Jefferson University suggests. Tatiana D. Zorina, M.D., Ph.D., an Assistant Professor in the Department of Bioscience Technologies, Jefferson School of Health Professions, ...
