Scientists find safer ways to detect uranium minerals
11-20-2006 · EurekAlert!The threat of "dirty" bombs and plans to use nuclear power as an energy source have driven Queensland University of Technology scientists to discover a new, safer way of detecting radioative contamination in the ground.Scientists from QUT have found a way of identifying, from a remote location, uranium deposits that have leached into the soil and water.

- Genomic test could help detect radioactivity exposure from terrorist attacks
04-02-2007 · EurekAlert!
In the event of a nuclear or radiological catastrophe -- such as a nuclear accident or a "dirty bomb" -- thousands of people would be exposed to radiation, with no way of quickly determining how much of the deadly substance has seeped inside their bodies. Scientists at Duke University Medical Center have developed a new blood test to rapidly detect levels of radiation exposure so that potentially life-saving treatments could be administered to the people who need them most.

- Polymers hold promise for safer gene delivery
09-07-2007 · Massachusetts Institute of Technology (MIT)
In work that could lead to safe and effective techniques for gene therapy, MIT scientists have found a way to fine-tune the ability of biodegradable polymers to deliver genes, which could be a safer technique than using viruses to carry genes.

- Cat fleas' journey into the vacuum is a 'one-way trip'
12-17-2007 · EurekAlert!
Homeowners dogged by household fleas need look no farther than the broom closet to solve their problem. Scientists have determined that vacuuming kills fleas in all stages of their lives, with an average of 96 percent success in adult fleas and 100 percent destruction of younger fleas. In fact, the results were so surprisingly definitive that the lead scientist, an Ohio State University insect specialist, repeated the experiments several times to be sure the findings were correct.

- Scientists discover novel way to remove iron from ferritin
11-02-2007 · EurekAlert!
A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, PhD, is the first to suggest that a small protein or heptapeptide could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or sickle cell disease.

- Neurons that detect motion rapidly switch between modes of data collection
02-28-2007 · EurekAlert!
Form does follow function, as far as visual cortex neurons tasked with perceiving action are concerned. Far from being the static nerve cells researchers believed them to be, capable of performing only a single function, scientists at the Salk Institute for Biological Studies found these neurons rapidly shift back and forth between two ways of collecting information about moving objects.

- 'Twinkle after effect' can help retinal patients detect vision loss quickly and cheaply
10-23-2007 · EurekAlert!
Scientists at Schepens Eye Research Institute have discovered a simple and inexpensive way for patients with retinal and other eye disease to keep track of changes in their vision loss. In a study published in this week's PLoS One (Oct. 24, 2007) they demonstrate that a compelling visual illusion known as the induced twinkle after-effect can accurately identify the location and breadth of actual blind spots in people with retinal disease

- Using a magnet to tune a magnet
08-01-2007 · EurekAlert!
An international research team, led by scientists at the London Centre for Nanotechnology, has found a way to switch a material's magnetic properties from "hard" to "soft" and back again -- something which could lead to new ways of controlling electromagnetic devices. The research will appear in the journal Nature on Aug. 2, and shows how a magnet can be "tuned" by subjecting it to a second magnetic field, perpendicular to the original.

- Contrast agent puts new light on diagnosing breast cancer
03-26-2007 · EurekAlert!
Scientists in the laboratory of Dr. John Frangioni, M.D., Ph.D., associate professor of medicine and radiology at Harvard Medical School, have developed a contrast agent that selectively targets and highlights malignant micro-calcifications in the breast, while ignoring similar micro-calcifications found in benign breast conditions. The new, simpler way to detect malignant tumors will be described in March at the 233rd national meeting of the American Chemical Society in Chicago.
