The microgravity conditions of space travel result in unique physiological demands on the human body. In particular, the absence of the continual mechanical stresses on the skeletal system that are present on Earth cause the bones to decalcify. Trabecular structure decreases in thickness...

A document discusses the changes made to a standard push-pull inverter circuit to avoid saturation effects in the main inverter power supply. Typically, in a standard push-pull arrangement, the unsymmetrical primary excitation causes variations in the volt second integral of each half of the excitation cycle that...

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that...

One day in 2010, a Rutgers physicist watched a store employee showcase a kitchen gadget that vacuum-seals food in plastic. The simple concept – an airtight seal around pieces of food – just might apply to his research: developing flexible electronics using lightweight organic semiconductors for...

An international team has developed transistors using natural cotton fibers — an innovation that represents a significant leap forward because it lays the groundwork for creating even more complex devices, such as cotton-based circuits, which in turn open doors to the creation of wearable electronic devices...

Students, teachers, and commercial companies have been taking advantage of the International Space Station's (ISS) unique environment for years. One of those companies, Houston-based Odyssey Space Research, plans to bring the experience to the rest of us via our mobile devices.
