NASA tracks Tropical Storm Podul's landfall approach to Vietnam

NASA's Aqua satellite passed over the South China Sea and provided forecasters with a visible image of Tropical Storm Podul as it moved closer to the coast of north and central Vietnam where it is expected to make landfall ...

Machine learning increases resolution of eye imaging technology

Biomedical engineers at Duke University have devised a method for increasing the resolution of optical coherence tomography (OCT) down to a single micrometer in all directions, even in a living patient. The new technique, ...

Universal algorithm set to boost microscopes

Thanks to the advent of super-resolution microscopes some 30 years ago, scientists can observe subcellular structures, proteins and living tissue with unprecedented precision. These microscopes operate by measuring the fluorescent ...
