Molecular machine may lead to new drugs to combat human diseases

... to cut out malfunctioning genes. Introns' unique capability of cutting and pasting apparently has been conserved since life evolved. "It's thought that RNA, or a molecule related to RNA, possibly were the first biomolecules, because they are capable of both performing work and carrying around their own genet...

Solution to Pollution: New Bacteria Eats Toxic Waste

...to pollution. “This project shows mother nature’s capability to be a master engineer,?said Ron Sims, biological and irrigation engineering department head. “Past disposal practices and accidental spills have put these carcinogens in our environment, and nature has figured out a way to cleanse herself. We want ...

Development of portable infectious disease detector

...sed in soft contact lenses.This has given them the capability to capture, manipulate, grow andstudy single living cells in extraordinarily small containers--volumesthat are barely larger than the cells themselves.Most sensors that have been developed to identify toxic agents aresingle purpose. That is, they can...

NIAID Initiates Trial of Experimental Avian Flu Vaccine

...unity is concerned that the virus will develop the capability of efficiently spreading from human to human and thus create a risk for a worldwide pandemic,?says NIAID Director Anthony S. Fauci, M.D. “NIAID has supported research on H5N1, the strain responsible for this deadly form of avian influenza, since 199...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

..., the facility provides the kind of drug discovery capability usually available only to pharmaceutical company scientists. Duke's new facility is a finalist for one of six $9 million National Institutes of Health (NIH) grants that will create a national network of publicly accessible small molecule facilities ...

Scientists discover that host cell lipids facilitate bacterial movement

...bility of the bacterium to move within cells. This capability is unique to Listeria and is not found in another intracellular bacteria, Shigella. Our experiments show that Listeria is a simplified model system for studying how phosphoinositides regulate the actin cytoskeleton, and this model promises to yield a...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

...perience improvement in vision and what resolution capability these patients might eventually have. "Although we hope that all patients receiving the chip will experience some improvement in visual function, we can't say for sure how these patients will respond to this new treatment since this is still an exper...

Researchers develop rapid diagnostic tool for pathogen identification

...n of co-infections.?/p> “The high multiplexing capability and sensitivity of the approach is provided by using the digital molecular weights of small molecules to code for the identity of the pathogens and detection of the molecular tags with high sensitive mass spectrometry, which can be potentially miniat...

Ophthalmologists implant five patients with artificial silicon retina microchip

"Although we hope that all patients receiving the chip will experience some improvement in visual function, we can't say for sure how these patients will respond to this new treatment since this is still an exper...

A frog's life is food for thought

...nt of their body mass and maximise their digestive capability from the outset," Ms Cramp said. Little is known about the effects of prolonged food deprivation on the gut of animals that go without food for long periods. Ms Cramp's study is helping explain why animals such as the green-striped burrowing frog ar...

These nanoengineered particles have the capability to effectively interface with biological molecules." ?Sohi Rastegar, a bioengineering expert and the NSF program director who oversees the agency's support of the Northwestern NSEC and several other bioengineering centers. "This will be a biosensing...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...mmunity, that elephants actually have the physical capability to send and receive low-frequency vibrations. To do that, they had to convince skeptical geophysicists, like Hart's brother, Byron Aranson. "It was a unique collaboration," Hart says. "We started with the physics of it, then moved to behavior and ho...

Researchers discover underwater volcano

...mersible Pisces V-a seven-foot sphere that has the capability to dive to depths of more than 6,000 feet, operated by NOAA's Hawaii Undersea Research Laboratory. The water surrounding the volcanic cone is extremely turbid due to hydrothermal activity and the vigorous vents that produce this volcanic "fog" are o...

Microscopes at microscopic size

...targets within the cells. Researchers can use this capability to examine cellular conditions for certain diseases or to develop new treatments by studying the way cells react to a drug. The biochips also raise the possibility of a micro-laboratory, the size of a credit card, which would be able to perform medi...

Computational Tool Predicts How Drugs Work In Cells, Advancing Efforts To Design Better Medicines

...uctase, findings that not only validate the tool’s capability but could also pave the way to investigations of a potentially new class of therapeutic compounds. In addition to Gardner, Collins, Schaus, and Elliott, the research team included Diego di Bernardo, an investigator at the Telethon Institute for Gene...
