Insights into severe form of dwarfism

Wed, 03/09/2014 - 4:19pm
A better understanding of the pathology of a severe form of dwarfism as well as a possible window of treatment have been discovered by researchers. Pseudoachondroplasia (PSACH) is a disorder that affects the cells in the growth plate, resulting in dwarfism, limb deformities, joint pain and early onset osteoarthritis. Children with PSACH show no signs of it at birth. Slowing of the long bone growth begins around age 2 and the cellular damage becomes extensive by age 4.

Number of Texans without health insurance drops under Affordable Care Act, survey shows

Wed, 03/09/2014 - 4:19pm
The percentage of Texans without health insurance dropped after the first enrollment period of the Affordable Care Act, according to a report. Even with nearly 400,000 newly uninsured adults, the report estimates Texas has now surpassed California to become the state with the highest number of uninsured residents. The report found the majority of the remaining uninsured adult Texans are Hispanic and low-income. Half of those uninsured are employed.

Exposure of pregnant women to certain phenols may disrupt growth of boys during fetal development and first years of life

Wed, 03/09/2014 - 4:18pm
Medical researchers have found that exposure to certain common phenols during pregnancy, especially parabens and triclosan, may disrupt growth of boys during fetal growth and the first years of life. Parabens are commonly used as preservatives in cosmetics and healthcare products and triclosan are an antibacterial agent and pesticide found in some toothpastes and soaps.

Breakthrough for carbon nanotube solar cells: Twice as efficient as current models

Wed, 03/09/2014 - 2:58pm
Lighter, more flexible, and cheaper than conventional solar-cell materials, carbon nanotubes (CNTs) have long shown promise for photovoltaics. But research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods. Scientists have now developed a carbon nanotube solar cell that is twice as efficient as its predecessors.

Nature or nurture? It's all about the message

Wed, 03/09/2014 - 2:57pm
Simply telling people that hard work is more important than genetics causes positive changes in the brain and may make them willing to try harder, a study shows. "Giving people messages that encourage learning and motivation may promote more efficient performance," said the lead investigator. "In contrast, telling people that intelligence is genetically fixed may inadvertently hamper learning."

Wind energy cuts the electricity bill

Wed, 03/09/2014 - 2:56pm
The promoting of renewable energy is at the heart of the current debate on energy policy. From an economic perspective, the question focuses on determining the cost of the feed-in tariff systems. A new study tackles this question empirically, and concludes that wind energy continues to produce greater savings than what its incentives amount to, while photovoltaic solar technologies are still in the development phase.

'Family meal' ideal is stressful, impossible for many families

Wed, 03/09/2014 - 2:56pm
Magazines, television and other popular media increasingly urge families to return to the kitchen, stressing the importance of home-cooked meals and family dinners to physical health and family well-being. But new research shows that home cooking and family meals place significant stresses on many families -- and are simply impossible for others.

'Drink responsibly' messages in alcohol ads promote products, not public health

Wed, 03/09/2014 - 2:53pm
Alcohol industry magazine ads reminding consumers to “drink responsibly” or “enjoy in moderation” fail to convey basic public health information, according to a new study. Federal regulations do not require "responsibility" statements in alcohol advertising, and while the alcohol industry's voluntary codes for marketing and promotion emphasize responsibility, they provide no definition for "responsible drinking."

'Brightpoints': New clues to determining the solar cycle

Wed, 03/09/2014 - 2:47pm
Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. However, the timing of the solar cycle is far from precise. Now, researchers have discovered a new marker to track the course of the solar cycle -- brightpoints, little bright spots in the solar atmosphere that allow us to observe the constant roiling of material inside the sun.

Scientists discover how to 'switch off' autoimmune diseases

Wed, 03/09/2014 - 1:21pm
Scientists have made an important breakthrough in the fight against debilitating autoimmune diseases such as multiple sclerosis by revealing how to stop cells attacking healthy body tissue. Rather than the body's immune system destroying its own tissue by mistake, researchers have discovered how cells convert from being aggressive to actually protecting against disease.
