Eliminating subsidies that help low- and moderate-income people purchase coverage through government-run health insurance marketplaces would sharply boost costs for consumers and cause more than 11 million Americans to lose their health insurance, according to a new RAND Corporation study. Modeling the likely effects of ending subsidies offered to individuals under the federal Affordable Care Act, researchers found that such a move would increase premium costs in the individual marketplaces by as much as 43 percent and cause enrollment to drop by 68 percent. "If subsidies ...

Two Michigan high school students, sisters Ilina and Medha Krishen, have developed screening tools using electronic stethoscopes to detect lung and heart disease. The sisters will present their findings at CHEST 2014 in Austin, Texas next week. Ilina Krishen became aware of the dangers of smoking and chemical air pollution when she saw the effects of lung disease on family members. Curious to find a way to detect early lung damage in people exposed to noxious air pollutants, Ilina, a high school senior at Port Huron Northern High School in Michigan, developed a screening ...

Adults typically believe that life gets better — today is better than yesterday was and tomorrow will be even better than today. A new study shows that even depressed individuals believe in a brighter future, but this optimistic belief may not lead to better outcomes. The findings are published in Clinical Psychological Science, a journal of the Association for Psychological Science. The research shows that middle-aged adults who had a history of depression tended to evaluate their past and current lives in more negative terms than did adults without depression, ...

TORONTO, Oct. 21, 2014--Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, according to a research paper published today in The Lancet. If the epidemic persists and grows, it's likely there will be more cases of the deadly virus exported to other countries, including Canada, via air travel, said Dr. Kamran Khan, a physician and researcher at St. Michael's Hospital. Dr. Khan, who examines global airline travel patterns to predict the spread of diseases, said that every month, three ...

VIDEO: In this video, a Salk researcher explains how cancer evolves to become drug resistant. Click here for more information. LA JOLLA—Like a colony of bacteria or species of animals, cancer cells within a tumor must evolve to survive. A dose of chemotherapy may kill hundreds of thousands of cancer cells, for example, but a single cell with a unique mutation can survive and quickly generate a new batch of drug-resistant cells, making cancer hard to combat. Now, scientists ...

PENSACOLA, Fla. – Ospreys do not carry significant amounts of human pharmaceutical chemicals, despite widespread occurrence of these chemicals in water, a recent U.S. Geological Survey (USGS) and Baylor University study finds. These research findings, published by Integrated Environmental Assessment and Management is the first published study that examines the bioaccumulation of pharmaceuticals in the water-fish-osprey food web. Pharmaceuticals have been finding their way into the environment, primarily through wastewater, urban runoff and even biosolids applied ...

JACKSONVILLE, Fla. — After following breast cancer patients for an average of eight-plus years, researchers say that adding trastuzumab (Herceptin) to chemotherapy significantly improved the overall and disease-free survival of women with early stage HER2-positive breast cancer. They found that the use of trastuzumab produced a 37 percent improvement in survival and a 40 percent reduction in risk of cancer occurrence, compared to patients treated with chemotherapy alone. These findings, published in the Journal of Clinical Oncology, demonstrate how important ...

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they've learned before may boost later learning. Scientists have already established that resting the mind, as in daydreaming, helps strengthen memories of events and retention of information. In a new twist, researchers at The University of Texas at Austin have shown that the right kind of mental rest, which strengthens and consolidates memories from recent learning tasks, helps boost future learning. The ...

ANN ARBOR, Mich. — Scientists have restored the hearing of mice partly deafened by noise, using advanced tools to boost the production of a key protein in their ears. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging. In a new paper in the online journal eLife, the team from the University of Michigan Medical School's Kresge Hearing Research Institute and ...

PHILADELPHIA – Blue light can both set the mood and set in motion important biological responses. Researchers at the University of Pennsylvania's School of Medicine and School of Arts and Sciences have teased apart the separate biological responses of the human eye to blue light, revealing an unexpected contest for control. Their work addresses the properties of melanopsin, a light-sensitive protein in the eye that establishes the rhythm of our day-night cycle and the familiar constriction of the pupil to bright light. They measured the pupil response to stimulation ...

WASHINGTON, DC – October 20, 2014 -- Lactobacillus species, commonly seen in yogurt cultures, correlate, in the guts of mouse models, with mitigation of lupus symptoms, while Lachnospiraceae, a type of Clostridia, correlate with worsening, according to research published ahead of print in Applied and Environmental Microbiology. "Our results suggest that the same investigation shold be performed in human subjects with lupus," says principal investigator Xin Luo of Virginia Tech, Blacksburg, VA. In the study, the investigators first showed that mouse models of lupus ...

For treating patients with prescription opioid dependence in primary care, buprenorphine maintenance therapy is superior to detoxification, according to a new study by Yale School of Medicine researchers published in the Oct. 20 issue of JAMA Internal Medicine. Prescription opioid dependence has been increasing for the last 15 years and now surpasses heroin dependence. Doctors are also writing more prescriptions for pain management, which has led to higher experimentation and addiction rates, according to lead author David Fiellin, M.D., professor of internal medicine ...

Scientists have developed new geochemical tracers that can identify hydraulic fracturing flowback fluids that have been spilled or released into the environment. The tracers have been field-tested at a spill site in West Virginia and downstream from an oil and gas brine wastewater treatment plant in Pennsylvania. "By characterizing the isotopic and geochemical fingerprints of enriched boron and lithium in flowback water from hydraulic fracturing, we can now track the presence of 'frac' fluids in the environment and distinguish them from wastewater coming from other ...

LIVERMORE, Calif. – New medications created by pharmaceutical companies have helped millions of Americans alleviate pain and suffering from their medical conditions. However, the drug creation process often misses many side effects that kill at least 100,000 patients a year, according to the journal Nature. Lawrence Livermore National Laboratory researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions (ADR) or side effects. They are using high-performance computers ...

Preexisting differences in the sensitivity of a key part of each individual's immune system to stress confer a greater risk of developing stress-related depression or anxiety, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published October 20 in the Proceedings of the National Academy of Sciences (PNAS). Inflammation is the immune system's response to infection or disease, and has long been linked to stress. Previous studies have found depression and anxiety to be associated with elevated blood levels of inflammatory molecules ...

CHAMPAIGN, Ill. — They help fish swim, but fins also advertise a fish's social standing and health. In a new study, researchers report that for the male bluefin killifish (Lucania goodei), each colorful fin presents its own messages to other fish. Researchers report their findings in the journal Behavioral Ecology. They're called "bluefin" killifish, but the first thing University of Illinois animal biology professor Rebecca Fuller noticed while she was snorkeling in a Florida stream was the killifishes' differently colored fins. In addition to having reflective ...
