New details about the strongest spider silk in the world

Many researchers dream of deciphering the amazing ability of spiders to create super strong, super light, and super flexible silk threads—but so far, no one has been able to replicate the spiders' work.

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous ...

Nondestructive testing of optical fiber diameters

The increased use of optical fiber has seen a greater focus on the precise control and measurement of its diameter. That is due to the diameter being vital for a wide range of fields, from high-speed optical communication ...

Determining the slenderization of wood pulp

Researchers from the Institute of Scientific and Industrial Research at Osaka University have devised a new method to determine the degree of fibrillation in wood pulp. By taking advantage of the intrinsic optical birefringence ...

Fabrics that protect against chemical warfare agents

A new coating for textile fibers shows promise for efficiently capturing toxic industrial chemicals and chemical warfare agents under real-world conditions, including high humidity. The research could lead to improved masks ...

Improved microendoscope brings cervical cancer into focus

Rice University researchers have added a clever spin—a rotating grating that removes out-of-focus light—to a cutting-edge, minimally invasive fiber-optic microscope that lets oncologists and surgeons zoom in on cancer ...
