Quantum physics and origami for the ultimate get-well card

Paper-based diagnostic tests are cheap, convenient and biodegradable. However, their use is limited by conventional dyes—which are not bright enough to show trace amounts of analyte, are prone to fading, and can be environmentally ...

Motion control at the nanoscale

NUS Physicists have designed a bipedal nanowalker that can change its walking manner and direction by adjusting the length of its stride. Deoxyribonucleic acid (DNA)-based nanowalkers are a class of molecular motors which ...

Chirality yields colossal photocurrent

A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature ...

Core technology for ultra-small 3-D image sensor

A KAIST research team developed a silicon optical phased array (OPA) chip, which can be a core component for three-dimensional image sensors. This research was co-led by Ph.D. candidate Seong-Hwan Kim and Dr. Jong-Bum You ...

Hybrid nanoantenna designed to manipulate visible light

A nanoscale optical antenna developed by researchers at A*STAR allows the manipulation of visible light waves on the scale of microchips. Such nanoantennae may enable the development of high-resolution imaging systems in ...

Instrument boosts analysis of small, extremely dark materials

Researchers have developed a new instrument that can analyze light reflected from very small or extremely dark materials such as some meteorite samples and VANTABlack, the darkest manmade substance created. The instrument ...

SDO spots two lunar transits in space

On Sept. 9, 2018, NASA's Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens when a celestial body passes between a larger body and an observer. This first lunar ...

The bright ways forests affect their environment

For decades scientists have tried to understand why forests emit the volatile gases that give pine forests their distinctive smell. A new study led by the University of Leeds may have found the answer.

Researchers combine spintronics and nanophotonics in 2-D material

Spintronics is an emerging field in which the spin of electrons, rather than the charge, is used to process data. Unfortunately, the spin only lasts for a very short time, making it difficult to exploit in electronics. Researchers ...
