Because of their symmetrical fractal wiring patterns, the devices can be cut to the size needed to provide the voltage and power requirements for specific applications. The modular generators could be inkjet printed on flexible substrates, including fabric, and manufactured using inexpensive roll-to-roll techniques. "The attraction of thermoelectric generators is that
Researchers at the University of Washington developed a device smaller than a toaster that can detect the level of hemoglobin in whole blood samples using optical absorbance. The work is published this week in AIP Advances, from AIP Publishing. Hemoglobin is a protein found in red blood cells that transports oxygen throughout
The potent combination also attacked satellite tumors and distant cancerous cells, completely curing two mice and effectively vaccinating one against the disease. The results appeared online in Scientific Reports on August 17. "The ideal cancer treatment is non-invasive, safe and uses multiple approaches," said Tuan Vo-Dinh, the R. Eugene and Susie E. Goodson
Known as "Coolief," the procedure can provide several months of relief from chronic arthritis pain for patients for whom surgery is not an option. It also decreases the need for a daily regimen of prescription medication and other over-the-counter pain-relieving drugs. "We're not taking away the arthritis, just the arthritis pain,"
The hypothesis referred to is the linear no-threshold hypothesis (LNT) promoted by Nobel Laureate Hermann Muller in 1946. Muller stated that the dose-response relationship is linear with no threshold dose, i.e., all radiation is harmful, regardless of how low the dose and dose rate. "The underlying intent of lowering future cancer
The finding may benefit both able-bodied people who are frequently on their feet -- think of the military infantry or athletic baby-boomers, for example -- as well as those who have been victims of stroke or other gait impairments. To gain an advantage over nature, North Carolina State University and Carnegie
Nanoparticles from combustion engines can activate viruses that are dormant in in lung tissue cells. This is the result of a study by researchers of Helmholtz Zentrum München, a partner in the German Center for Lung Research (DZL), which has now been published in the journal Particle and Fibre Toxicology.
