Take the dime in your wallet. Now imagine a chip no larger than a fraction of that coin that can detect the faintest traces of thousands of different chemicals, using over 32 different infrared light-emitting lasers...

This efficient and portable way to sense chemicals—toxic or benign—may make the largest waves in medicine as a noninvasive diagnostic device through “breath analysis.” Its high sensitivity can be manipulated to detect certain chemicals in the breath indicative of conditions including diabetes, ulcers, colon cancer, and cystic fibrosis...

...increase the proportion of U-235--the uranium atoms that start and continue a nuclear chain reaction. Uranium that feeds a power plant needs only 3% enrichment, but a nuclear warhead requires at least 90% enrichment, and more centrifuges. The difference is so significant that international inspectors would probably detect the enrichment change unless Iran chose to enrich its uranium covertly, slowing the process. A country with civilian nuclear plants could choose to reprocess spent atomic fuel into plutonium, which can also be used for bombmaking. That would require the construction of a separate reprocessing facility. You need...

...model for future research on the disease, Murray said. To this end, she and her team decided to make their genetic data available online. “This is a big step forward,” Murray said. “We are trying to detect mutations that allow organisms to become resistant—what kinds of things might happen in the evolution of these organisms that allows them to be so successful, that allow resistance to happen in the first place.” The genetic sequencing data can be used to study what mutations cause to happen...

...Lowry wrote, "conservatives bristle at the sense of being told what to do, and they detect a tone of moral superiority in her advocacy of children's programs and health care." That's ironic since conservatives present themselves as the ones who hold the moral high ground, preaching family values and taking every opportunity to tell the masses how to live their lives. Perhaps Lowry should have said that when conservatives see Clinton, they see themselves - and don't like it very much. Rob Hernandez, Libertyville...
