One species, many genomes

...very tenth gene was so defective that it could not fulfill its normal function anymore! Results such as these raise fundamental questions. For one, they qualify the value of the model genomes sequenced so far. "There isn’t such a thing as the genome of a species," says Weigel. He adds "The insight that t...

Study finds mix of disease processes at work in brains of most people with dementia

...t Alzheimer’s disease pathology in their brains to fulfill accepted neuropathologic criteria for Alzheimer’s disease, although in life only 47 were clinically diagnosed with probable or possible Alzheimer’s disease. “We know that people can have Alzheimer’s pathology without having symptoms,” says Dallas...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...asingly compromised by aircraft noise. In order to fulfill their mandate to protect natural, cultural, and historic resources, as well as visitor experience, NPS has developed analytical tools to assess lost opportunities to hear and respond to the sounds of nature. At the Grand Canyon, efforts are being m...

Danish researches solve virus puzzle

...d read the code for the proteins to be produced to fulfill the needs of the living cell. The task of the ribosomes is to read the code of the host cell, but the virus has the special trick that its RNA resembles that of the host cell, and hence, the ribosomes of the host cell will start reading the viral RNA...

'Marathon mice' elucidate little-known muscle type

...cally perform intense and rapid activities. To fulfill these varied roles, muscles vary in their proportion of "slow-twitch" muscle fibers (types I and IIA), ideal for slow and constant roles, and "fast-twitch" fibers (type IIB), better suited to rapid and sudden activity of shorter duration. The fiber t...

NHGRI aims to make DNA sequencing faster, more cost effective

...look forward to seeing which of these technologies fulfill their promise and achieve the quantum leaps that are needed to take DNA sequencing to the next level." "$1,000 Genome" Grants NHGRI's "Revolutionary Genome Sequencing Technologies" grants have as their goal the development of breakthrough techn...

Schepens scientists are first to discover angiogenesis switch inside blood vessel cells

... compete for the use of the same lipid membrane to fulfill opposite missions, growth and regression, respectively. This finding could lead to new, more targeted drugs for diseases such as cancer, diabetic retinopathy and macular degeneration. The study, titled "Regulating angiogenesis at the level of PtdIns-...

Neurons grown from embryonic stem cells restore function in paralyzed rats

...be used to treat injuries and disease and begin to fulfill their great promise. The successful demonstration of functional restoration is proof of the principle and an important step forward. We must remember, however, that we still have a great distance to go," says Elias A. Zerhouni, Director of the Nation...

Role of protein in immune response may aid HIV research

...t the liver's constant protein production may help fulfill the organ's preventative role as a blood filter. ...

Plant gene related to cancer treatment may foster new oncology drugs

...with ATP, the main cell energy source, in order to fulfill their mission. The best known member of another class of transport proteins, PIN1, also may be a transporter, but appears to function primarily as an aide rather than the delivery truck for auxin transport, Murphy said. This finding revealed that PI...

Key mechanism in genetic inheritance during cell division identified

...crotubule binding ring might be uniquely suited to fulfill the functions of the Dam1 complex. In comparison with the purified Dam1, the Dam1 mutants produced partially formed rings that reduced microtubule binding. "Because the stability of a microtubule is thought to be largely governed by the lateral inte...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...mbiotic nitrogen fixation. Thus, plant hemoglobins fulfill roles analogous to those of animal hemoglobins, as well as novel roles that are apparently unique to symbiotic nitrogen fixation.

Priming embryonic stem cells to fulfill their promise

... and othertissues and organs. However, in order to fulfill their therapeuticpromise, scientists believe that stem cells must first be coaxed todifferentiate, or mature, into precursors of specialized cell typesfound in the body.Embryonic stem cell differentiation is complex and far from fullyunderstood.
