Ultrathin, flat lens resolves chirality and color: Multifunctional lens could replace bulky, expensive machines

Many things in the natural world are geometrically chiral, meaning they cannot be superimposed onto their mirror image. Think hands -- right and left hands are mirror images but if you transplanted a right hand onto a left, you'd be in trouble. Certain molecules are chiral, including DNA and amino acids.

Imaging with the multispectral chiral lens forms two images of the beetle, Chrysina gloriosa, on the color camera. The left image was formed by focusing left-circularly polarized light reflected from the beetle and the right image was formed from right-circularly polarized light. The left-handed chirality of the beetle's shell can clearly be seen.

NASA Technology Applied in Breast Cancer Study

Getting spacecraft ready for launch may have more to do with medical research than you think. For a new study on microbes that may be associated with a history of breast cancer, researchers at NASA's Jet Propulsion Laboratory, Pasadena, California, employed the same sequencing and analysis methods used for examining bacteria in spacecraft assembly rooms. Those techniques were designed for planetary protection -- ensuring that NASA spacecraft do not contaminate other worlds.

New imaging method reveals nanoscale details about DNA: Enhancement to super-resolution microscopy shows orientation of individual molecules, providing a new window into DNA's structure and dynamics

Researchers have developed a new enhanced DNA imaging technique that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists gain important insights into what goes wrong when DNA becomes damaged or when other cellular processes affect gene expression.

Researchers refine method for detecting quantum entanglement

RMIT quantum computing researchers have developed and demonstrated a method capable of efficiently detecting high-dimensional entanglement.

Entanglement in quantum physics is the ability of two or more particles to be related to each other in ways which are beyond what is possible in classical physics.
