CAMBRIDGE, Mass., Jan. 18, 2011 -- Physicists and bioengineers have developed an optical instrument allowing them to control the behavior of a worm just by shining a tightly focused beam of light at individual neurons inside the organism. The pioneering optogenetic research, by a team at Harvard University, the University of Pennsylvania, and the University of Massachusetts Medical School, is described this week in the journal Nature Methods. Their device is known as the CoLBeRT (Controlling Locomotion and Behavior in Real Time) system for optical control of freely moving ...

A study led by Dr. Tom P. Aufderheide, professor of emergency medicine at The Medical College of Wisconsin, shows an alternative method of cardio-pulmonary resuscitation increases long-term survival of patients. The study, which is published in the January 19th, 2011 online version of Lancet, and will be in an upcoming publication of Lancet, determined that active compression-decompression cardio-pulmonary resuscitation (CPR) with augmentation of negative intrathoracic pressure gave patients a better chance of survival. When the pressure inside the thorax decreases, ...

CHICAGO – January 18, 2011 – Maintaining periodontal health may contribute to a healthy respiratory system, according to research published in the Journal of Periodontology. A new study suggests that periodontal disease may increase the risk for respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia. These infections, which are caused when bacteria from the upper throat are inhaled into the lower respiratory tract, can be severely debilitating and are one of the leading causes of death in the U.S. The study included 200 participants ...

A complex sugar may someday become one of the most effective weapons to stop the spread of cholera, a disease that has claimed thousands of lives in Haiti since the devastating earthquake last year. A technique developed by University of Central Florida scientists would allow relief workers to test water sources that could be contaminated with the cholera toxin. In the test, the sugar dextran is coated onto iron oxide nanoparticles and then added to a sample of the water. If the cholera toxin is present, the toxin will bind to the nanoparticles' dextran. This is because ...

EVANSTON, Ill. --- Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past. The material exhibits a high thermoelectric figure of merit that is expected to enable 14 percent of heat waste to electricity, a scientific first. Chemists, physicists and material scientists at Northwestern collaborated to develop the material. ...

LA JOLLA, CA – January 18, 2011 – Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation. With the report of their work scheduled to appear in the online Early Edition of Proceedings of the National Academy of Sciences this week, the researchers now plan to optimize ...

CHAMPAIGN, Ill. — Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria. Chemists at the University of Illinois and collaborators in Taiwan studied a type of enzyme found in humans, plants, fungi, parasites, and many bacteria that begins the synthesis of triterpenes – one of the most abundant and most ancient classes of molecules. Triterpenes are precursors to steroids such as cholesterol. "These enzymes are important drug targets," said chemistry ...

While every cell of an organism contains the same genes only a proportion are expressed in any tissue at a given stage in development. Knowing the extent of gene transcription is valuable and a team of European researchers has generated an atlas of gene expression for the developing mouse embryo. This will be a powerful resource to determine co-expression of genes and to identify functional associations between genes relevant to development and disease. The findings will be published next week in the online, open access journal PLoS Biology. The comprehensive, interactive ...

Severe asthma in early childhood may lead to premature loss of lung function during adolescence and more serious disease during adulthood, researchers at Emory University School of Medicine report. Early identification and treatment of children with severe asthma is important to help stem asthma progression. In an article available online in the January issue of the Journal of Allergy and Clinical Immunology at http://www.jacionline.org/article/S0091-6749%2810%2901651-9/fulltext, Anne M. Fitzpatrick, PhD, and W. Gerald Teague, MD, and colleagues report on their study of ...

A new study at Rochester Institute of Technology indicates that the incidence of maltreatment, including neglect and physical and sexual abuse, is more than 25 percent higher among deaf and hard-of-hearing children than among hearing youths. The research also shows a direct correlation between childhood maltreatment and higher rates of negative cognition, depression and post-traumatic stress in adulthood. The study, which was presented at the 2010 annual meeting of the Association of Behavioral and Cognitive Therapies, is one of the first to compare childhood maltreatment ...

We all want an apology when someone does us wrong. But a new study, published in Psychological Science, a journal of the Association for Psychological Science, finds that people aren't very good at predicting how much they'll value an apology. Apologies have been in the news a lot the last few years in the context of the financial crisis, says David De Cremer of Erasmus University in the Netherlands. He cowrote the study with Chris Reinders Folmer of Erasmus University and Madan M. Pillutla of London Business School. "Banks didn't want to apologize because they didn't ...

COLUMBIA, Mo. – Frigid weather may seem like a good excuse to avoid workouts, stay inside and overindulge in comfort foods. However, health experts from the University of Missouri have found that these tendencies leave most people feeling less content during the winter months. MU researchers say people should establish new traditions to increase happiness and avoid wintertime woes. Instead of resolving to make drastic new year changes, establish healthy traditions for the winter months, MU nutrition and exercise physiology experts recommend. Incorporate activities ...

The newly released 2011 Thomson Reuters - HCPlexus National Physicians Survey (NPS) links doctors' fears that their pay will go down under the Patient Protection and Affordable Care Act (PPACA), commonly called Healthcare Reform Act (HCRA), with their concerns that the quality of care will also deteriorate. The study includes responses from 2,958 doctors of varying specialties and practice types, from all 50 states plus the District of Columbia. The NPS is the most comprehensive survey of physicians surrounding their thoughts on the future of healthcare, including ideas ...

Atrazine is one of the most widely used herbicides in North American corn production, but heated controversy remains over the 50-plus-year-old product. Several other herbicides are used in corn production, and a host of non-chemical tactics are sometimes used, too. If the use of atrazine is restricted or banned altogether, how will sweet corn growers cope? A recent University of Illinois study shows sweet corn can be grown successfully without atrazine, but given today's approach, perhaps not very often. "We wanted to know the implications of using less atrazine in current ...

LA JOLLA, CA—Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer's disease—early-onset familial Alzheimer's—which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin's productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their proper targets. Without it, budding motor neurons misread their guidance signals and get stuck in the spinal cord. By putting genes associated with Alzheimer's disease ...

ANN ARBOR, Mich.---The decreases in Earth's snow and ice cover over the past 30 years have exacerbated global warming more than models predict they should have, on average, new research from the University of Michigan shows. To conduct this study, Mark Flanner, assistant professor in the Department of Atmospheric, Oceanic and Space Sciences, analyzed satellite data showing snow and ice during the past three decades in the Northern Hemisphere, which holds the majority of the planet's frozen surface area. The research is newly published online in Nature Geoscience. Snow ...

Convalescent plasma therapy—using plasma from patients who have recovered from an infection to treat those with the same infection—has been used to treat multiple diseases. However, the efficacy of this treatment in patients with severe 2009 H1N1 influenza is unknown.
