See, feel, hear and control your environment, virtually (July 3, 2012) -- Scientists have transformed vast amounts of data into applications and systems that are able to analyze crowd behavior, allow remote energy management or even tell where some of the windiest spots in the city center are. ... > full story
Charting autism's neural circuitry: Deleting single gene results in autism-like behavior and immunosuppressant drug prevents symptoms (July 2, 2012) -- Deleting a single gene in the cerebellum of mice can cause key autistic-like symptoms, researchers have found. They also discovered that rapamycin, a commonly used immunosuppressant drug, prevented these symptoms. ... > full story
The advantages of being first (July 2, 2012) -- How people make choices depends on many factors, but a new study finds people consistently prefer the options that come first: first in line, first college to offer acceptance, first salad on the menu -- first is considered best. ... > full story
Kids with behavior problems, disabilities bullied more, more likely to bully others (July 2, 2012) -- Students receiving special-education services for behavioral disorders and those with more obvious disabilities are more likely to be bullied than their general-education counterparts -- and are also more likely to bully other students, a new study shows. ... > full story
Autism, schizophrenia and bipolar disorder may share common underlying factors, family histories suggest (July 2, 2012) -- New research points to an increased risk of autism spectrum disorders among individuals whose parents or siblings have been diagnosed with schizophrenia or bipolar disorder. ... > full story
Botulinum toxin a shot in the arm for preventing multiple sclerosis tremor (July 2, 2012) -- Botulinum toxin may help prevent shaking or tremor in the arms and hands of people with multiple sclerosis (MS), according to new research. ... > full story
Success reported in treating autism spectrum disorder in mice (July 2, 2012) -- Using a mouse model of autism, researchers have successfully treated an autism spectrum disorder characterized by severe cognitive impairment. ... > full story
New brain receptor for drug 'fantasy' identified (July 2, 2012) -- Researchers are closer to understanding the biology behind GHB (gamma-hydroxybutyric acid), a transmitter substance in the brain, best known in its synthetic form as the illegal drug fantasy. ... > full story
New way to grow, isolate cancer cells may add weapon against disease (July 2, 2012) -- A new method to isolate and grow the most dangerous cancer cells could enable new research into how cancer spreads and, ultimately, how to fight it. Researchers found that while a traditional culture of cancer cells has only a few capable of starting new tumors, a soft gel is capable of isolating tumor-repopulating cells and promoting the growth and multiplication of these cells in culture. The new culture technique could allow researchers to better study metastatic cancers. ... > full story
War-related climate change would reduce substantially reduce crop yields (July 2, 2012) -- Though worries about “nuclear winter” have faded since the end of the Cold War, existing stockpiles of nuclear weapons still hold the potential for devastating global impacts. Experts say that the climate effects of a hypothetical nuclear war between India and Pakistan would greatly reduce yields of staple crops, even in distant countries. ... > full story
Activity of rare genetic variant in glioma validated (July 2, 2012) -- Researchers have validated a link between a rare genetic variant and the risk of glioma, the most common and lethal type of brain tumor. The validation study also uncovered an association between the same rare genetic variant and improved rates of survival for patients with glioma. ... > full story
Rare leukemia-causing protein discovered (July 2, 2012) -- Researchers have discovered a new gene target for leukemia therapy. Researchers found that by inhibiting in animal models the protein Vav3, which controls cell signaling, the development of this leukemia -- known as BCR-ABL lymphoid leukemia -- is delayed. ... > full story
Genes may play role in educational achievement (July 2, 2012) -- Researchers have identified genetic markers that may influence whether a person finishes high school and goes on to college, according to a national longitudinal study of thousands of young Americans. ... > full story
Researchers block pathway to cancer cell replication (July 2, 2012) -- Research suggests that patients with leukemia sometimes relapse because standard chemotherapy fails to kill the self-renewing leukemia initiating cells, often referred to as cancer stem cells. In such cancers, the cells lie dormant for a time, only to later begin cloning, resulting in a return and metastasis of the disease. One such type of cancer is called pediatric T cell acute lymphoblastic leukemia, often found in children, who have few treatment options beyond chemotherapy. ... > full story
In vitro study identifies potential combination therapy for breast cancer (July 2, 2012) -- A new study demonstrates an effective combination therapy for breast cancer cells in vitro. The findings raise the possibility of using this type of combination therapy for different forms of breast cancer, including those that develop resistance to chemotherapy and other treatments. ... > full story
Hormone discovered that preserves insulin production and beta cell function in diabetes (July 2, 2012) -- Researchers have found protective, anti-diabetic functions for a hormone that, like insulin, is produced by the islet cells of the pancreas. The new hormone was found to stimulate insulin secretion from rat and human islet cells and protect islet cells in the presence of toxic, cell-killing factors used in the study. ... > full story
Cell biology: New insights into the life of microtubules (July 2, 2012) -- Every second, around 25 million cell divisions take place in our bodies. This process is driven by microtubule filaments which continually grow and shrink. A new study shows how so-called motor proteins in the cytosol can control their dynamics. ... > full story
Surprising culprit behind chemo resistance in rare cancer (July 2, 2012) -- Researchers have shown how an aggressive form of multiple myeloma resists chemotherapy. Multiple myeloma is a rare cancer of plasma cells in the bone marrow. Though the finding has no immediate benefit for patients, the scientists say it could help guide research into better treatments. ... > full story
Physical activity needed to reap benefits of dietary restriction (July 2, 2012) -- Dietary restriction alone does not extend lifespan – at least in fruit flies. Flies, which share many genetic similarities with humans, need physical activity in order to live longer on a Spartan diet. If the same axiom holds true in humans, those practicing caloric restriction in hopes of living longer need to make sure they eat enough to avoid fatigue. ... > full story
'Self-distancing' can help people calm aggressive reactions, study finds (July 2, 2012) -- A new study reveals a simple strategy that people can use to minimize how angry and aggressive they get when they are provoked by others. ... > full story
Electronic medical record improves physician compliance of reviewing portal images, study suggests (July 2, 2012) -- The use of an electronic medical record for reviewing portal images dramatically improves compliance with timeliness and record keeping, according to a new study. Portal images are used to verify the positioning of patients during daily radiation treatments to improve the accuracy of the radiation field placement, to reduce exposure to normal tissue and to deliver accurate dose to tumor volumes. ... > full story
Innate immune system protein provides a new target in war against bacterial infections (July 2, 2012) -- Scientists have identified a possible new approach to defeating bacterial infections by targeting an innate immune system component in a bid to invigorate the immune response. ... > full story
Years before diagnosis, quality of life declines for Parkinson's disease patients (July 2, 2012) -- Growing evidence suggests that Parkinson's disease often starts with non-motor symptoms that precede diagnosis by several years. In the first study to examine patterns in the quality of life of Parkinson' disease patients prior to diagnosis, researchers have documented declines in physical and mental health, pain, and emotional health beginning several years before the onset of the disease and continuing thereafter. ... > full story
Cutaneous human papillomavirus infection a risk factor for skin cancer (July 2, 2012) -- Researchers conducted a case control study and found associations between having antibodies to certain types of cutaneous human papillomavirus and a kind of skin cancer called squamous cell carcinoma. According to the researchers, evidence has been emerging that cutaneous human papillomavirus infection (not the mucosal HPV infection that is associated with cervical cancers) may be an additional risk factor for SCC. ... > full story
Measuring the uncertainties of pandemic influenza (July 2, 2012) -- A major collaboration between US research centers has highlighted three factors that could ultimately determine whether an outbreak of influenza becomes a serious epidemic that threatens national health. The research suggests that the numbers in current response plans could be out by a factor of two or more depending on the characteristics of the particular pandemic influenza. ... > full story
Censoring social media fans flames of social unrest (July 2, 2012) -- Is social media censorship a means to quell a modern uprising? Some politicians and law enforcers during the political turbulence of 2011 thought so but recent research suggests that uncensored citizens experience less violence and longer periods of peace between outbursts than communities subject to censorship. ... > full story
