A football helmet design that listens to physics Posted: 05 Feb 2016 02:32 PM PST A shock-absorbing football helmet system being developed could blunt some dangerous physics that today's head protection ignores.

Pioneering discovery leads to potential preventive treatment for sudden cardiac death Posted: 05 Feb 2016 02:30 PM PST Roughly 15 years ago, a team of researchers discovered the precise malfunction of a specific protein in the heart that leads to hypertrophic cardiomyopathy, a common culprit in cases of sudden death in young athletes. A team of scientists have now used some of these findings to develop a possible treatment to prevent this inherited disease that can cause the heart to thicken and stop pumping blood effectively, leading to heart failure.

Study evaluates pay-for-performance program for Medicaid children in an ACO Posted: 05 Feb 2016 02:30 PM PST The first pay-for-performance (P4P) evaluation of pediatricians under a full-risk Medicaid accountable care organization (ACO) for children shows P4P incentives were partially responsible for higher performance on quality measures across Partners for Kids' primary care network of employed and affiliated physicians.

Gene family turns cancer cells into aggressive stem cells that keep growing Posted: 05 Feb 2016 02:30 PM PST An examination of 130 gene expression studies in 10 solid cancers has found that when any of four related genes is overexpressed, patients have much worse outcomes, including reduced survival.

Does shopping helps you feel better after a setback? Posted: 05 Feb 2016 12:35 PM PST If you just flubbed a big work project, you might be feeling down on yourself. Maybe you'll head to the mall to indulge in a little retail therapy. Buying products is a common way to make yourself feel better, with half of all Americans reporting that they do it.

Chromosomes reconfigure as cell division ends Posted: 05 Feb 2016 11:45 AM PST Cells reach a state called senescence when they stop dividing in response to DNA damage. This change can matter greatly to health, but scientists do not yet have a clear picture of how this change impacts the genome. A new study shows that a cell's chromosomes become physically reconfigured at senescence, leading to significant differences in what genes are expressed.

'Pushback' against constant connectivity also reflected in images Posted: 05 Feb 2016 10:54 AM PST People expressing the wish to resist constant online connectivity -- dubbed "pushback" by researchers -- is manifested as powerfully in images as in text, further study has found.

Online shopping might not be as green as we thought Posted: 05 Feb 2016 10:54 AM PST A new study provides insight into the impacts of home shopping on vehicle operations and greenhouse gas emissions.

Using the physics of your perfect pancake to help save sight Posted: 05 Feb 2016 10:51 AM PST Understanding the textures and patterns of pancakes is helping scientists improve surgical methods for treating glaucoma.

Single-lesion biopsy may be insufficient to choose therapy targeting resistance mutations Posted: 05 Feb 2016 10:50 AM PST When metastatic tumors driven by drug-targetable genetic mutations become resistant to a targeted therapy drug, the usual practice is to test a single metastatic lesion for new mutations that can guide the selection of next-line therapies. But this strategy may miss additional targetable mutations that arise in different metastases, a new study finds.

Honey’s potential to save lives by destroying harmful fungus Posted: 05 Feb 2016 08:26 AM PST The healing powers of honey have been known for thousands of years. Now a researchers has discovered a powerful link between a medicinal type of honey and the destruction of a fungus that can cause blindness or even death.

Smart thermostat puts energy money saving at household fingertips Posted: 05 Feb 2016 08:26 AM PST Researchers are aiming to develop a 'smart' thermostat to help UK households save money on their energy bills. The prototype autonomous device allows users to control their heating based on the price they want to pay rather than setting it by temperature alone, which existing smart thermostats such as Nest, do.

Parental preference for boys damages girls’ self-esteem and happiness Posted: 05 Feb 2016 08:26 AM PST While most studies of parental sex discrimination explore the devastating social and demographic effects of a cultural preference for boys, a new study examines its psychological effects on the girls themselves.

The significance of non-motor microtubule-associated protein in maintaining synaptic plasticity thorough a novel mechanism Posted: 05 Feb 2016 08:05 AM PST NMDA glutamate receptors, which function as receptors that bond with glutamates, are known to be deeply involved in animal memory and learning. In order for memories to be created inside the brain, these NMDA glutamate receptors must first be transported to and accumulated in the synapses.

Super-resolution microscope allows visualization of the mechanism that maintains cell polarity: The key is to repeatedly establish temporary polarity Posted: 05 Feb 2016 08:05 AM PST Cells are not uniform spheres; they generally come in a variety of disparate shapes. In the broadest sense, this variation in shapes is known as cell polarity, and it is an essential property for a variety of cell functions. Growth in accordance with their polarity allows cells to shape themselves in forms appropriate to their function. It has been found that the establishment and maintenance of polarity is governed by the interdependent relationship between the polarity marker protein on the plasma membrane (cell membrane), actin, the microtubule cytoskeleton, and membrane vesicle transport. The polarity marker determines the polarity site, and with membrane vesicle transport toward it, site-specific growth (polarity growth) is achieved. However, when the plasma membrane elongates due to fusion of membrane vesicles, there have been questions about how polarity markers are maintained without being scattered over the elongated plasma membrane.

Femtosecond laser pulses push spintronics and magnonics to the limit Posted: 05 Feb 2016 08:05 AM PST Scientists have achieved the ultimate speed limit of the control of spins in a solid state magnetic material.
