B-TENG Device: Tiny Wind Turbine Harvets Energy From a Breeze

Chinese scientists develop a tiny wind turbine that can harvest energy from a light breeze. The developers hope that someday it can be used to power electronic devices, provide electricity for communities where energy is scarce, and even compete with traditional wind turbines.

New Microendoscopy Technique Can Record Images of Red Blood Cells Pixel by Pixel

Endoscopies have evolved from taking images of the esophagus, intestines, and organs, using bulky equipment to minimally-invasive procedures using precision lasers. A new endoscopy technique, however, involves an even smaller device, one that is measured in microns, with the ability to record pixel-by-pixel images of red blood cells.

The Physics of Throwing a Football

Whenever there is a discussion about the best way to throw a football, people will often focus on the grip, the footwork, and even the arm motion before release. What you may not hear as much is the physics involved.

German Scientists Design World's Smallest Ultrasound Detector

Using nanotechnology and silicon-on-insulator technology, scientists develop a tiny ultrasound detector that can create images of cells and small fragments of tissue. The developers hope the technology can also be expanded outside medical applications such as industrial uses.

Researchers Develop Carbon Nanotube Water Filters

Desalination processes to produce potable water are essential for all communities, especially in areas where water is scarce. However, traditional methods go through multiple processes resulting in additional costs and energy. Scientists developed artificial carbon nanotubes as an efficient filtration system.
