New super-fast MRI technique demonstrated with song 'If I Only Had a Brain'

Science Daily - Tue, 21/04/2015 - 5:21pm
With a new magnetic resonance imaging (MRI) technique, the vocal neuromuscular movements of singing and speaking can now be captured at 100 frames per second. The sound of the voice is created in the larynx, located in the neck. When we sing or speak, the vocal folds--the two small pieces of tissue--come together and, as air passes over them, they vibrate, which produces sound. After 10 years of working as a professional singer in Chicago choruses, a researcher's passion for vocal performance stemmed into study to understand the voice and its neuromuscular system, with a particular interest in the aging voice.

Likely cause of 2013-14 earthquakes: Combination of gas field fluid injection and removal

Science Daily - Tue, 21/04/2015 - 5:20pm
A seismology team finds that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes near Azle, Texas, from late 2013 through spring 2014. The team identified two intersecting faults and developed a sophisticated 3-D model to assess changing fluid pressure within a rock formation, and the stress changes induced by both wastewater injection and gas production wells.

Surprising contributor to Rett syndrome identified

Science Daily - Tue, 21/04/2015 - 5:20pm
The immune system is designed to protect us from disease. But what if it was malfunctioning? Would it make a disease worse? That appears to be the case with Rett syndrome, a neurodevelopmental disorder, and possibly in other neurological disorders as well.

Strontium atomic clock accurate to the second -- over 15 billion years

Science Daily - Tue, 21/04/2015 - 5:20pm
In another advance at the far frontiers of timekeeping , the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one second in some 15 billion years -- roughly the age of the universe.

New gene therapy success in a rare disease of the immune system

Science Daily - Tue, 21/04/2015 - 5:20pm
The efficacy of gene therapy treatment for Wiskott-Aldrich syndrome has been demonstrated by researchers. Wiskott-Aldrich syndrome is a rare congenital immune and platelet deficiency which is X-linked and has an estimated prevalence of 1/250,000. It is caused by mutations in the gene encoding the WAS protein (WASp) expressed in hematopoietic cells. This disease, which primarily affects boys, causes bleeding, severe and recurrent infections, severe eczema and in some patients autoimmune reactions and the development of cancer.

Battle in the gut: Immune cells help 'good bacteria' triumph over 'bad bacteria'

Science Daily - Tue, 21/04/2015 - 5:19pm
The body's immune system may be the keeper of a healthy gut microbiota, report scientists. They found that a binding protein on white blood cells could affect whether or not mice produced a balanced gut microbiota. Without the protein, harmful bacteria were more easily able to infect. Why this happens is unclear, but it may be that the immune system has a way to sense the presence of invading intestinal bacteria.

Childhood cancer survivors more likely to claim social security support as adults

Science Daily - Tue, 21/04/2015 - 5:17pm
Childhood cancer survivors are five times more likely to have enrolled in a Social Security disability assistance program than other citizens, a new American study concludes. "The long-term impact of cancer can affect other issues besides health outcomes," said the lead author on the study. "We need to do a better job of helping people function throughout their lives, not just when they're finishing their cancer therapy."

Most cancer patients want tumor profiling, even if it reveals other genetic risks

Science Daily - Tue, 21/04/2015 - 5:17pm
Most cancer patients would opt for tumor profiling even if the test revealed that they or their families were at risk for other genetic diseases, according to a study. The study showed that despite the risk for receiving information about other potentially serious health problems, 59% of the cancer patients would agree to tumor profiling if offered by their physician. In a scenario where tumor profiling was already ordered, 79% of patients stated they wanted to know all of the information obtained.

Optical Tech Can Boost Wi-Fi Systems' Capacity With LEDs

Slashdot - Tue, 21/04/2015 - 5:07pm
chasm22 writes: Researchers at Oregon State University have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The system can potentially send data at up to 100 megabits per second. Although some current WiFi systems have similar bandwidth, it has to be divided by the number of devices, so each user might be receiving just 5 to 10 megabits per second, whereas the hybrid system could deliver 50-100 megabits to each user.
