Born with a love of speech

...-like sounds, which resemble a chorus of Martians, closely mimic the melodic aspects of speech. They also contain a fundamental frequency ?the core pitch of a voice, such as baritone or soprano, that helps us clue in to the identity of a voice. These non-speech stimuli were developed by Drs. Sonya Bird and G...

New hybrid virus provides targeted molecular imaging of cancer

...and prostate cancer." Their next step was to work closely with the team of M. D. Anderson researcher Juri Gelovani, M.D., Ph.D., chair of the Department of Experimental Diagnostic Imaging, a pioneer in development of molecular-genetic imaging tools. "We could see by using positron emission tomography that ...

Ticks, flukes, and genomics: Emerging pathogens revealed

.... "By comparing so many different pathogens, some closely related and others diverse, we're able to identify genes linked to different diseases and organisms," explains molecular biologist Julie Dunning Hotopp of TIGR, first author of the PLoS Genetics paper. Because the pathogens causing ehrlichiosis are o...

New influenza vaccine takes weeks to mass produce

...ing from a stocked recombinant baculovirus bank, a closely matched vaccine can be massively produced within 2 weeks." PSC has recently signed a Letter of Intent which will support commercial scale manufacturing with the capacity to produce 6 Million doses of monovalent pandemic vaccine per week. ...

Why nerve cells work faster than the theory allows

... the Ruhr-Universität Bochum has now examined more closely the speed and threshold of action potentials in nerve cells of the cerebral cortex of the mammal brain. They were able to show that action potentials are initiated extremely rapid here. Although a single action potential lasts a millisecond, a strong...

Earth Rx: A microbial biotechnology prescription for global environmental health

..., lakes and groundwater. "All of these issues are closely interrelated," says Bruce Rittmann, director of the Center for Environmental Biotechnology in the Biodesign Institute at ASU. "For example, most of the pollution wastes that we worry about are really just energy put in the wrong place and causing tro...

Researchers discover a new genetic cause of Alzheimer's disease

...s in our body are strictly regulated, primarily by closely controlling the amount of each protein that is produced. The promoter of a gene has the most important control function in this process. In younger Belgian and Dutch Alzheimer's patients (younger than 70), the researchers found genetic variations i...

Minor mutations in avian flu virus increase chances of human infection

...A) structure from the Viet04 virus was found to be closely related to the 1918 virus HA, which caused some 50 million deaths worldwide. Using a recently developed microarray technology-hundreds of microscopic assay sites on a single small surface-the study showed that relatively small mutations can result ...

Hantavirus found in African wood mouse

...irus," said ter Meulen. The new virus appears most closely related to the Dobrava virus, originally discovered in Slovenia. The researchers have also grown the virus in cell culture, which is notoriously difficult to do with hantaviruses. Now they can easily test to see which antibodies react with the viru...

For some young fish, early gene expression is a clear harbinger of fated lifestyle

...el. Researchers now report that fish that are very closely related genetically show dramatically different patterns of actual gene expression if they have adopted different lifestyle fates. Moreover, and perhaps more surprisingly, less-related individuals from geographically different populations nonetheless...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...ces (HHS) today announced the creation of two new, closely related initiatives to speed up research on the causes of common diseases such as asthma, arthritis and Alzheimer's disease. One initiative boosts funding at the National Institutes of Health (NIH) for a multi-institute effort to identify the genet...

Losing sleep undoes the rejuvenating effects new learning has on the brain

...icted rats rather than sleep-deprived rats to more closely mimic the common human experience of inadequate sleep during the work week, said lead investigator Ilana Hairston of both the University of California, Berkeley, and Stanford University. The paper, "Sleep restriction suppresses neurogenesis induced b...

Novel method reveals how menthol discovery could point towards new or improved pain therapies

...ins. "Because our ability to sense temperature is closely linked to our ability to sense pain, it is not surprising that the misregulation of temperature-activated ion channels can result in chronic pain syndromes," said Ardem Patapoutian, associate professor at Scripps Research and member of GNF, who direc...

Variation in bitter-taste receptor gene increases risk for alcoholism

...ions within taste receptors. So we decided to look closely at these taste receptor genes." Because taste receptors tend to vary a lot in the general population, Goate and colleagues had the opportunity to look at a large number of differences in genetic sequences and determine whether certain sequences migh...

For the first time: Longevity modulated without disrupting life-sustaining function

...-1 pathway since it is prompted by insulin and the closely related insulin-like growth factor-1 or IGF-1. IGF-1 is the main trigger for childhood growth but continues to exert growth stimulating effects throughout an individual's life. Insulin, which is best know for controlling blood glucose levels, has add...

Study reveals classic symbiotic relationship between ants, bacteria
