Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...nt MRI "reporter." A typical MRI scan detects and analyzes signals given off by hydrogen protons in water molecules after they are exposed to a magnetic field and radiofrequency pulses. These signals are then converted into an image. Ahrens' new MRI reporter alters the magnetic field in its proximity, causin...

Making medicine 'smarter'

"The outcome of the proposed research is expected to have substantial implications in health care by contributing to the improved diagnosis of indeterminate breast lesions by non-invasive i...

Terahertz imaging may reduce breast cancer surgeries

...ealthy tissue being removed. If a histopathologist analyzes the tissue and finds tumor at or near the edges, this indicates that there is a higher chance of cancer recurrence. A second operation is required to remove more tissue, involving additional hospital resources and increased risk of patient morbidity....

...tion of mass spectrometry and gas chromatography - analyzes the composition of biological samples. It can be used to quickly and simultaneously look into a fruit's amino acids, organic acids, sugar and vitamins. Dr. Alisdair Fernie, head of the Institute's "Central Metabolism" research group, discovered that...

Computer scientist sorts out confusable drug names

...then created a new program for them, BI SIM, which analyzes and compares the spelling of words. PPC combined Kondrak's programs into a system that the FDA has been using for the past two years to analyze proposed drug names and rank them in terms of confusability, both phonetically and orthographically, wit...

Purdue creates new low-cost system to detect bacteria

...iversity have developed a new low-cost system that analyzes scattered laser light to quickly identify bacteria for applications in medicine, food processing and homeland security at one-tenth the cost of conventional technologies. The technique - Bacteria Rapid Detection Using Optical Scattering Technology ...

Researcher gives hard thoughts on soft inheritance

...ting in the May issue of Nature Reviews Genetics, analyzes recent and past research in epigenetics and the history of evolution and proposes that epigenetics should be considered a form of soft inheritance, citing examples in both the plant and mammalian kingdoms. In doing so, he evokes the pre-Dar...

How the US drug safety system should be changed

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...e is a highly specialized mass spectrometer, which analyzes the mass of small molecular ions formed when a focused ion beam runs across the surface of a sample. ''You take everything in the beam's focal area, which is about 100 nanometers in diameter and about 10 nanometers deep for our experiment, and you ob...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

...he various colors decoded by a spectrometer, which analyzes the wavelengths of light. Another device called an interferometer, which calculates structural information based on the interaction between two waves of light, provides the data required to create three-dimensional images. To demonstrate the devi...

Leading reason for corneal transplants comes into focus

...process-of-elimination gene-hunting technique that analyzes inheritance patterns in families with relatively large numbers of affected individuals and trace genetic traits co-inherited or "linked" with the disorder. Researchers search for a common location for all the linked traits until they wind up with a s...

Weighty viruses

...he light goes to a measuring device that precisely analyzes the scattering signal. The scattered light is different from the initial light beam because the virus particle in the electric field of the ion trap begins to oscillate. This oscillation depends on the mass (and charge) of the virus. The team was ...

Vaccine to cope with viral diversity in HIV

Rapid, Low-Cost DNA Testing

...erg's method is part of a much larger process that analyzes DNA. First, a technician extracts the DNA from the blood, tissue, or food. This typically take up to an hour. Second, there is generally not enough DNA to analyze, so it must be chemically amplified. This also takes apprximately one hour. The new pro...
