Researchers have found a way to use the full beam of a laser light to control and manipulate minute objects such as single cells in a human body, tiny particles in small volume chemistry,...

By using light waves instead of electric current to transmit data, photonic chips — circuits for light — have advanced fundamental research in many areas from timekeeping to telecommunications....

Fabricated using inexpensive and widely available organic pigments used in printing inks and cosmetics, an artificial retina was developed that consists of tiny pixels like a digital camera sensor on...

Motion capture (Mocap) is a technique used in the film industry to digitally track a human actor's movements and precisely transfer those motions to an animated figure. But it has other applications as...

Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a surgical camera inspired by the eye of the morpho butterfly. The...

Duke University researchers have developed a handheld probe that can image individual photoreceptors in the eyes of infants. The technology, based on adaptive optics, will make it easier for...

Before launching their latest science experiment, University at Buffalo researchers bought more than 200 types of tea, chocolate, herbs, and other foodstuffs. The goal wasn't to stock up...

Fluorescence-based biosensing and bioimaging technologies are widely used in research and clinical settings to detect and image various biological species of interest. While...

Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert...

Defects in the lattice of diamonds produce more than just beautiful coloration. A new approach developed by researchers at UC Berkeley's College of...

The latest advances in 3D technologies are revolutionizing the ability to measure the human body, and this is having a tremendous impact on the healthcare industry and in the development of...

Compression therapy is a standard form of treatment for patients who suffer from venous ulcers and other conditions in which veins struggle to return blood from the lower extremities....

A smaller, faster and more sensitive laser power meter in the form of a folding mirror uses a capacitor-based force transducer and merges optical elements, namely a high reflectivity mirror,...

Researchers have developed an endoscope as thin as a human hair that can image the activity of neurons in the brains of living mice. Because it is so thin, the endoscope can reach...

Japanese researchers describe a new implantable device no bigger than the width of a coin that can be used to control brain patterns. The device, which can be read about...

A new way of taking images in the mid-infrared part of the spectrum, developed by researchers at MIT and elsewhere, could enable a wide variety of applications, including thermal imaging, biomedical...

An inability to handle misty driving conditions has been one of the chief obstacles to the development of autonomous vehicular navigation systems that use visible light. These systems are...

A new optical imaging system developed at Columbia University uses red and near-infrared light to identify breast cancer patients who will...

Like sandblasting at the nanometer scale, focused beams of ions ablate hard materials to form intricate three-dimensional patterns. The beams can create tiny features in the...

Nearly four million infants in developing countries die each year within a month of birth due to complications of prematurity, low birth weight,...
