'Hybrid'Semiconductors Show Zero Thermal Expansion; Could Lead To Hard
The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity -- and not incidentally, ruin the chip. Thermal expansion can also separate semiconducting materials from the substrate, reduce performance through changes in the electronic structure of the material or warp the delicate structures that emit laser light. Study: Brain Structures Contribute To Asthma
The mere mention of a stressful word like "wheeze"can activate two brain regions in asthmatics during an attack, and this brain activity may be associated with more severe asthma symptoms, according to a study by University of Wisconsin-Madison researchers and collaborators. Chernobyl Disaster Caused Cancer Cases In Sweden
A statistically determined correlation between radioactive fallout from the Chernobyl accident and an increase in the number of cases of cancer in the exposed areas in Sweden is reported in a study by scientists at Linköping University, Örebro University, and the County Council of Västernorrland County. Sensor Network Mimics Synchronized Calling By Frogs, Cicadas
The modern world is filled with the uncoordinated beeping and buzzing of countless electronic devices. So it was only a matter of time before someone designed an electronic network with the ability to synchronize dozens of tiny buzzers, in much the same way that frogs and cicadas coordinate their night-time choruses. Bacteria Could Make New Library Of Cancer Drugs That Are Too Complex T
Researchers at the University of Warwick are examining a way of using bacteria to manufacture a new suite of potential anti-cancer drugs that are difficult to create synthetically on a lab bench. The bacterium Streptomyces coelicolor naturally produce antibiotics called prodiginines. Designer Molecule Detects Tiny Amounts Of Cyanide, Then Glows
A small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. Although the fluorescent molecule is not yet ready for market, its creators report that the tool is already able to sense cyanide below the toxicity threshold established by the World Health Organization. 'Self-seeding' of cancer cells may play a critical role in tumor progr
Cancer progression is commonly thought of as a process involving the growth of a primary tumor followed by metastasis, in which cancer cells leave the primary tumor and spread to distant organs. A new study shows that circulating tumor cells -- cancer cells that break away from a primary tumor and disseminate to other areas of the body -- can also return to and grow in their tumor of origin, a newly discovered process called "self-seeding." The Julie/Julia Project
This blog mostly from 2002-2003 (and later made into a book) chronicles the efforts over one year of an American cook to follow all 536 recipes in the first edition of Julia Child's "Mastering the Art of French Cooking."Notes: Includes some piquant language. For navigation through the latter part of the site, click on "Home"and make your way back. A Salon.com blog. A Guide to the Disaster Declaration Process and Federal Disaster Assis
This website explains how state governors, through the Disaster Relief and Emergency Assistance Act (1988), request and obtain a presidential disaster declaration after disasters such as fires, hurricanes, tornadoes, and floods. Discusses the declaration process and the types of individual, public, and hazard mitigation assistance that might be provided for a disaster. From the Federal Emergency Management Agency (FEMA). Everything I Need to Know About (Real) Robots I Learned From Transform
Transformers don’t care about people, period. That's what I learned growing up in the 1980s, religiously watching a race of robot Titans from outer space wage a secret war on Earth.
