differently. Compared to normal cells, cancer cells are smaller, more dense and wrinkled, like a raisin. Gao proposes that cancer cells will react differently in response to his laser-beam system. Early detection of cancer is a critical indicator o...

...lts from Envisat's Radar Altimetry-2 (RA-2), which bounces
thousands of radar pulses each second off the sea surface in order to detect ocean eddies and currents. "Our model for forecasting has a maximum five km mesh size, which is demanding in terms of computing power, but which we need to resolve surface ...

...of shallow rivers. The acoustic instrument, which bounces
sound waves off the river bottom, can be coupled with radio modems and hand-held computers and is enabling technicians to get out of the stream, ensuring greater safety and providing more accurate and more frequent data for some stream conditions. U...

against deep geologic formations, much like in a giant pinball machine and is bounced or reflected into areas at great distance from the epicenter of the earthquake. That's why ground water in Pennsylvania was showing the effects of the power releas...

off the cell surface and the bacteria goes unscathed, explained McCafferty. Ramoplanin, however, attaches itself to an essential sugar within the peptidoglycan molecule. This interaction would be much more difficult for evolutionary resistance mecha...

...is like going through a pinball machine. The ball bounces
off of a number of different risk and protective factors. In the end, the accumulation of all of these 'encounters,' plus intangible factors such as free will, religion, culture, and family lead to a final phenotype. High risk doesn't equal alcohol...

are continuous all along this,then that greatly enhances thedetection capabilities," said Ross. The MIRD can detect compounds in concentrations as low as 10 micromolar (onemolecule in a million). In lab tests, the newer design was 1,000 times more s...
