Discovery of size changes of Bacillus spores may lead to simpler, faster anthrax detector

... turnaround time would be 12-24 hours. A device to scan for Bacillus spores of a certain size and swelling time could provide an answer in about 10 minutes. "This wouldn't be a foolproof way of saying, "You've got anthrax spores,'" added Price, "but it would be a flag for you to go to the next step, perha...

Braille found to be essential, regardless of age of blindness

The average age at onset of blindness in the late blind group was age 19.2 (range, seven to 36). All blind subjects, but no sighted subjects, were fluent Braille readers. A...

Study of living eye in real time now possible with optics technology

... would like to treat. "The way we use our laser to scan the retina to produce an image, it may be possible to use the technique for treatment. While you're imaging a microaneurysm, for example, if we could track that feature we may be able to then turn on a treatment laser and blast it with the same preci...

Thus morphing is among the most important research fields in computer animation and bears a considerable potent...

GenoMyc binding

... Amati and colleagues used bioinformatics tools to scan the human genome and identify genes containing one or more E-boxes in the proximity of their promoter (the portion of the gene where transcription begins). Of the 1630 gene loci identified, approximately 700 underwent further biochemical characteriza...

Imaging technique may help in confirming, monitoring treatment of malignant brain tumors

The researchers found sodium concentrations in cancer cells were elevated by an average of 50 percent compared to the other no...

Genetic reconnaissance identifies new colon cancer genes

... of the human genome sequence allows scientists to scan sequences to identify kinases, and the increased speed with which DNA can be sequenced enables us to rapidly search for mutations in those kinases in human cancers," said Markowitz. In beginning their survey of the kinome for kinases activated in col...
