Sensory feedback during speech: The brain attunes to more than just sound

... production. The findings support the idea that accurate acoustic quality is not the brain's only goal during the motor control of speech--precision in expected somatosensory feedback cues is also an important endpoint. ...

'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

...iple agents are important, particularly when early accurate diagnosis can alter treatment or assist in containment of an outbreak," stated W. Ian Lipkin, MD, director of the Greene Infectious Disease Laboratory at the Mailman School’s Department of Epidemiology. He added, "To address the challenges of emergi...

Gene signature assesses breast cancer outcomes

...uthors found that the 70-gene signature was a more accurate predictor of disease outcomes than assessment with the Adjuvant Online! software. Moreover, statistical analysis indicated that most of the prognostic information provided by traditional risk classifiers was included in the gene classifier. The aut...

Protein structure initiative launches new resources for the scientific community

...l data and create higher-resolution images; More accurate screening processes to detect crystals suitable for imaging; and Improved systems for making proteins from machines, instead of cells. These developments have reduced the cost, time, and space needed to carry out structural studies, as wel...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...rs’ in the model equations in order to create an accurate representation of what is going on inside the cell. A simple example is the conversion between Fahrenheit and Celsius temperatures, said mathematician Layne Watson. "You could use several pairs of Fahrenheit and Celsius readings for the same temperat...

A sweet step toward new cancer therapies

...se bonds break, the resulting fragments don't give accurate information about either the protein's identity or the exact type and position of sugars present. To get around that problem, researchers have used a process called electron capture dissociation (ECD) instead of the usual "shake-it-til-it breaks" ...

HIV dementia alarmingly high in Africa

...ld," Sacktor says. Sacktor says there’s little accurate data about HIV dementia patients in other parts of the world --- current estimates of the number of HIV-positive patients who have dementia range from 9 percent to 54 percent. ...

'The eyes have it' -- Autism research yields surprising results

...han conventional still pictures, gives a much more accurate measure of the abilities of autistic children. ...s to participants. Our study indicates that a more accurate measure of the abilities of those with autism can be obtained through the use of sophisticated digit...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...dual variability, these factors don't yield a very accurate prediction. A liver biopsy can indicate the amount of damage to the liver up until the time of the biopsy, but can't reveal how much future damage will occur. The new test assessed by Cheung and his colleagues is a way to hedge the bets. The...

Hay fever can send work productivity down the drain

...h found that the ImmunoCAP IgE blood test was more accurate in diagnosing allergies when compared to other specific IgE blood tests. While IgE testing is traditionally the realm of allergists, more and more family physicians are starting to use it, she said. But patients who think they may have allergies n...

Over a century after disappearing, wild elk return to Ontario

.... "Our challenge for the future will be to develop accurate methods to estimate elk numbers and locations, so that elk can be managed in a sustainable manner, and in a way that minimizes conflicts between elk and humans." ...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...ling software. According to the researchers, an accurate understanding of the key molecular events required the simulations to run for some six million time steps over 12 nanoseconds (a nanosecond is one billionth of a second) in order to capture enough of the motion and shape changes of the enzyme as it i...

Stretching DNA to the limit

...d. These "stretch—release" measurements enable the accurate determination of changes in the elasticity of the DNA strands. Upon exposure to UV light, the force profile of the viral DNA changes dramatically in a dose-dependent manner. The force curve of intact DNA is characterized by a plateau region. This cha...

Sunshine pill for prostate cancer in 2009

... you will find them. But this does not give you an accurate estimate of how many people will go on to develop advanced disease. In fact death rates are going down, which means that the market for this drug is probably pretty static.' James also points out that it is far from certain that the Phase III tri...

Gene expression test reveals ER and HER-2 status of breast tumors

...ment. The gene expression tests were 90 percent accurate for both receptors, which makes them comparable to, if not better than, existing pathology tests. "This moves us closer to developing an integrated single genomic test that could estimate the risk of cancer relapse after surgery, determine the E...

New research shows that flu is a trigger of heart attacks

...than death certificates enabled us to be much more accurate about the cause of death, because doctors often neglect to list flu on a death certificate if their patients have died from a heart attack and, conversely, heart attack symptoms can be missed in patients suffering from flu and pneumonia." They fou...

Homing pigeons get their bearings from their beaks

...logists concerning their potential application for accurate drug targeting and even as a data storage device. The main problem, however, lies in their synthetic production. According to Gerta Fleissner and her colleagues, "Even though birds have been producing these particles for millions of years, the main...

Scientists use nanoparticle to discover disease-causing proteins

...samples are collected, researchers can't obtain an accurate picture of biochemical mechanisms related to illnesses such as cancer and heart disease. Tao and his research team used dendrimers because they can pass through cell walls efficiently with little disturbance to the cells and then label specific pr...
