Researchers Sculpt Optical Micro-Structures

Materials scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute of Biologically Inspired Engineering used a new framework to grow sophisticated optical micro-components, including trumpet-shaped assemblages that operate as waveguides.

Is Pluto a Planet? Scientists Seek New Definition

In 2006, the International Astronomical Union demoted Pluto to "non-planet" status. Johns Hopkins University scientist Kirby Runyon led a group of six researchers to draft a new definition of "planet" — one that includes more than 100 other celestial bodies, including Pluto. The proposal was presented at the Lunar and Planetary Science Conference, hosted in Houston, Texas on March 21.

Origami-Inspired Robot Can Ride with a Rover

The Pop-Up Flat Folding Explorer Robot (PUFFER) that’s in development at NASA’s Jet Propulsion Laboratory in Pasadena, CA, was inspired by origami. It travels with a rover, and its lightweight design can flatten itself, tucking in its wheels and crawling into places rovers can’t fit.

Non-Toxic Material Generates Electricity Through Heat, Cold Air

Imagine a body sensor powered by one's jewelry, or a cooking pan that charges a cell phone in a few hours.

Using a combination of the chemical elements calcium, cobalt, and terbium, University of Utah researchers created an efficient, inexpensive and bio-friendly material that generates electricity through a thermoelectric process involving heat and cold air.

Corrective 'Eyeglasses' Created For X-Ray Research Facilities

Even when an X-ray beam is steered and focused with advanced mirrors and other optics, abnormalities can creep in. These problems have names familiar to those with imperfect vision, such as “astigmatism” or “coma” and “spherical” errors. And just like our eyes, an X-ray beam can lose power and focus when its alignment isn’t perfect. To address this challenge with X-rays, researchers designed and built special spectacles, or corrective phase plates, for use at light sources that use high-intensity X-rays to probe matter in fine detail.

Researchers Craft New Material That Could Improve LED Screens

Researchers working at the Ultrafast Laser Lab at the University of Kansas successfully created a new bilayer material, with each layer measuring less than one nanometer in thickness. The new material, that someday could lead to more efficient and versatile light emission, was made by combining atomically thin layers of molybdenum disulfide and rhenium disulfide.

Optical Generation of Ultrasound Via Photoacoustic Effect

Limitations of the piezoelectric array technologies conventionally used for ultrasonics inspired a group of University College London researchers to explore an alternative mechanism for generating ultrasound via light, also known as the photoacoustic effect. Coupling this with 3-D printing, the group was able to generate sound fields with specific shapes for potential use in biological cell manipulation and drug delivery.
