Chemists create 'Superbowl' molecule; May lead to better health

...al of the American Chemical Society. Shaped like a miniature football stadium, the molecule is capable of delivering a wide range of drugs ?from painkillers to chemotherapy cocktails ?to specific areas of the body, potentially resulting in improved treatment outcomes and perhaps saving lives, the researchers s...

Purdue proves concept of using nano-materials for drug discovery

...lt and demonstrated a prototype for a new class of miniature devices to study synthetic cell membranes in an effort to speed the discovery of new drugs for a variety of diseases, including cancer. The researchers created a chip about one centimeter square that holds thousands of tiny vessels sitting on top of...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

...le. Through these incisions, the surgeons insert a miniature cutting and vacuuming device that removes the gel in the middle of the eye and replaces it with saline. They then make a pinpoint opening in the retina through which they inject fluid to lift up a portion of the retina from the back of the eye, creat...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

...e metabolism of the brain, the heart and cancer. A miniature version of PET was developed and is used in much the same way to image small animals. Small animals, especially mice, play a fundamental in the study of human biology and disease. Mice have nearly the same set of genes as humans, offering an opportu...

At the molecular level, the predator is the prey

...r level, another battle rages. And in this second, miniature realm, it's the newt who's the aggressor. Biologists at Indiana University Bloomington, Utah State University and the University of Utah present evidence in this week's Nature that a toxin produced by the rough skinned newt, Taricha granulosa, has f...

New miniaturised chip dramatically reduces time taken for DNA analysis

...niversitat Autònoma de Barcelona has developed new miniature sensors for analysing DNA. The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain. These sensors can be applied to many different tasks...

Team Invents Device For Weighing Individual Molecules

... creation of microchips, each possessing arrays of miniature mass spectrometers, which are devices for identifying molecules based on their weight. Today, high-throughput proteomics searches are often done at facilities possessing arrays of conventional mass spectrometers that fill an entire laboratory and can...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...l. Lovley's team speculated that the pili might be miniature wires extending from the cell that would permit Geobacter to carry out its unique ability to transfer electrons outside the cell onto metals and electrodes. This was confirmed in a study in which microbiologist Gemma Ruegera teamed with physicists Ma...

Vietnam war technology could aid elephant conservation

...mbers. Another team tried to use a US Army surplus miniature seismic system to detect crop raiding Asian elephants in Sri Lanka, but the work was abandoned after the elephants began digging up the geophones and destroying them. Making accurate estimates of elephant populations is essential for their conservat...

No small feat: First ever gene therapy success for muscular dystrophy achieved

... cell of the body's 600 muscle groups. By using a miniature gene, similar in function to the one defective in CMD, and applying a newly developed method for "systemic" gene delivery, the Pitt researchers have shown that gene therapy for muscular dystrophy is both feasible and effective in a mouse model of esp...

Sensors, a smart dose of medicine for cancer treatment

...SFET), to do just that. "Several features, such as miniature size, response to types of radiation involved in radiotherapy, compatibility with microprocessors that enables real-time read-out and low cost, make these semiconductor sensors eminently suitable for the intended application," says Jaksic. The diode...

Radiotherapy advance points way to noninvasive brain cancer treatment

...ogy necessary for eventual treatment would involve miniature synchrotron light sources, which could be similar in size and cost to an MRI machine. De Stasio says the next steps will include animal and possibly human clinical trials. "If we do see that we can cure animals from their cancers, then it's worth i...

Encoded metallic nanowires reveal bioweapons

...ied out on the spot, not in a laboratory. Portable miniature biodetection systems that can detect multiple pathogens simultaneously would be ideal for this task. American researchers from Lawrence Livermore National Laboratory led by Jeffrey Tok, in collaboration with groups at Stanford University, University...

UCSD researchers develop 'smart petri dish'

...body. But by designing a porous silicon chip with miniature wells similar to those in muffin tins, the UCSD researchers were able to mimic the extracellular matrix of the liver and keep the liver cells alive. On this chip, individual cells are contained within well-like structures, 2 to 1,500 nanometers in d...
