Novel Circuit Design Boosts Wearable Thermoelectric Generators

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

Gold Nanostars and Immunotherapy Vaccinate Mice Against Cancer

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

Tuning out Arthritis Pain with Radio Energy

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,"

Diagnostic Radiation Exposure Safe for Children, Experts State

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
