When the sixth annual Scientific Computing and Automation Conference and Exposition begins in Philadelphia tomorrow, conferees will be hearing about hundreds of scientific software packages that are now on the market. By contrast, in 1985, when the first conference was held, only a few applications were available for technical users of microcomputers, mostly in the area of data management and statistics. There were no more than a handful of software packages at the dawn of the so-called microc

Software Helps Researchers In Sorting Through The Human Genome

The Human Genome SIDEBAR : Selected Suppliers of Software for Gene Discovery and Analysis Genetics has been an informational science since the elucidation of DNA's structure. Today's researchers say the field shifted to a more computational mode in 1990-the year that research groups began mapping genes to specific chromosomal sites for the Human Genome Project. "That year was pivotal, because it was then that the need to sequence significant amounts of DNA became compelling," says Richard Gib

Image-Processing Software Makes Gains As Desktop Tool
Laurel Joyce | Feb 16, 1992 | 6 min read
A picture may not be worth a thousand words to a scientist unless it can be manipulated to yield useful information. One way of gleaning such data is computerized image processing, a technique for quantifying visual images. With an image-process- ing system, a geologist can build contour maps from satellite photos, a plant physiologist can count and measure individual cells in a leaf, and a molecular biologist can analyze an autoradiograph from a DNA sequencing gel. In the past decade, the com

Nanotechnology hit the big time in July 1995, when it debuted on the television show, The Outer Limits. In an episode entitled "The New Breed," a scientist develops nanorobots capable of repairing damaged cells and correcting physical defects. But, like any good morality play, the experiment goes horribly wrong, turning a panacea into a nightmare. Clearly, nanotechnology makes for good science fiction, but scientists have been working to make it an interesting reality, too. Nanotechnology refers
Applications Of Image Analysis Systems Expand Beyond The Research Lab

TIME EFFICIENT: The AMBIS radioisotopic imager from Scanalytics/CSPI. Already an invaluable tool in some basic research, image analysis is edging into the classroom and the clinic. "Any field of life science that can put a video camera onto a microscope will begin to use image analysis," predicts Richard Cardullo, an associate professor of biology at the University of California, Riverside. In general, the technique acquires, digitizes, and then processes a microscope or scanned image, enhan
