Interfering RNA silences genes in 'slippery' immune cells

...ren's Hospital of Philadelphia combined laboratory technologies in using RNA interference to manipulate human T ce... such manipulation. Their technique combines three technologies already accessible to lab investigators: nucleofection, siRNA expression cassettes, and siRNA expres...

Copying nature could save us energy, study shows

New technologies that mimic the way insects, plants and animals ove...th extremes of heat, up to 70 per cent of man-made technologies manipulate energy, often increasing the amount used, in order to resolve the problem. However, new ...

Innovative method for creating a human cytomegalovirus vaccine outlined

...developing a CMV vaccine, although the recombinant technologies available today should help to streamline the task. CMV infection is widespread in the U.S., according to the Centers for Disease Control and Prevention. Between 50 and 80 percent of adults are infected with CMV by the time they reach 40 years of a...

DOE publishes research roadmap for developing cleaner fuels

...tlines a detailed research plan for developing new technologies to transform cellulosic ethanol--a renewable, cleaner-burning, and carbon-neutral alternative to gasoline--into an economically viable transportation fuel "Cellulosic ethanol has the potential to be a major source for transportation fuel for America...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

...for Transport. It will develop e-Science and grid technologies to enable data from a network of mobile sensors to be gathered and interpreted. The e-Science technologies developed will be generic enough for use in other applications of mobile sensor networks, for exampl...

Making a face: A new and earlier marker of neural crest development

... Yale and Caltech demonstrate with three different technologies -- immunostaining of proteins, in situ hybridization and multiplex RT-PCR of mRNAs -- that formation of neural crest cells in chick embryos is independent of both mesoderm and neural tissues. They also identify, Pax7, as an early marker of neural cre...

Acidity in the brain could hold the key to stroke treatment

...will use advanced Nuclear Magnetic Resonance (NMR) technologies to allow MRI scanners to create detailed images of pH in the brain. The images will be used to compare healthy (neutral, pH 7) and damaged (acidic, lower pH) areas of the brain, and to measure how the pH of the brain changes over time, with the aim ...

Study finds that a woman's chances of having twins can be modified by diet

...y since 1975, about the time assisted reproductive technologies (ART) were introduced. The intentional delay of childbearing has also contributed to the increase of multiple-birth pregnancies, since older women are more likely to have twins even without ART. "The continuing increase in the twinning rate into th...

New GI technologies improve internal organ visualization

As visualization technologies like ultrasound continue to improve in quality and...ated and dangerous for the patient, but the use of technologies that can improve visualization of the area can increase the accuracy of the interventions. The hear...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...an urgent need for speedy medical analysis. Such technologies can also give the pharmaceutical industry improved ways to screen for new drugs by being able to run several types of tests simultaneously on an extremely small scale. The next step in developing this technology is under way in Hayes' laboratory an...

UC Davis researchers move biotechnology closer to replacing electronic pacemakers

...ls do not normally regenerate, but we now have the technologies to make new human heart cells using stem cells. And, we can also customize these cells to treat diseases," he said. ...

NASA technology helping injured US troops

...East Hartford, Conn., licensed these patented NASA technologies and modified the cable-compliant system into an ad...y important to NASA to facilitate licensing of our technologies when possible for the benefit of the broader community," said Nona Minnifield Cheeks, chief of Godda...

Finding a better way to make biodiesel

... So Lin and his research team started looking for technologies that would create an easier, more efficient and mo... economical process. They were also hoping to find technologies that would effectively make biodiesel out of raw materials such as used restaurant oils and animal f...

Nanowire arrays can detect signals along individual neurons

...vidual neurons and neuronal networks, but existing technologies are relatively crude: Micropipette electrodes poked into cells are invasive and harmful, and microfabricated electrode arrays are too bulky to detect activity at the level of individual axons and dendrites, the neuronal projections responsible for el...

Production of key Alzheimer's protein monitored for first time in humans

...learance rates," Bateman says. The test combines technologies that have been available for some time but only through recent technical and procedural advances has become sufficiently sensitive. Via an intravenous drip, scientists give test subjects a form of the amino acid leucine that has been very slightly al...

Creating a window on 'oceans in motion'

...out the back side of the moon. "Revolutionary new technologies open the path not just to smarter fisheries management, to better sea life conservation measures, and to the potential of abundant and sustainable stocks of commercial fish, they will also provide scientists with a massive increase in observations of...

Neuronal cell cultures kept on the straight and narrow

...ry NIST program to develop biochemical measurement technologies based on microfluidics. ...

Purdue creates new low-cost system to detect bacteria

...oducts are safe, but industry is trying to develop technologies that will very quickly identify organisms," Robinson said. "The same sort of thing holds true for clinical microbiology and other laboratories. With our light-scattering method, it takes less than five minutes to identify harmful organisms after they...

Progress being made in exploring potential use of stem cells to treat heart disease

... years will undoubtedly bring new developments and technologies to unravel these processes, leading to clinical applications of stem cell-based therapies for heart disease." ...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...ted supply interruptions, other types of fuels and technologies are needed to help pick up the slack. A group of experts in science, engineering and public policy from the Georgia Institute of Technology, the Imperial College London and the Oak Ridge National Laboratory recommend a comprehensive research and pol...
