A fast method for manufacturing a heart-on-a-chip using a UV laser could pave the way for straightforward tests of how heart tissue reacts to new clinical drugs. The platform, developed by researchers at Harvard University, uses a UV micropatterning method...

With the help of electronic microscopy, scientists have tracked defects in the surface of two-dimensional photonic crystals. But there are difficulties with bulk photonic crystals. There is no way for scientists to research the interiors of these unusual crystals. So...

Miniature spectrometers with ultra-resolving power could soon be realised, by taking inspiration from the abdominal scales of Australian peacock spiders, an international research team report in Nature Communications....

The technology is not invasive, so physicians could use the scanner frequently to monitor the retina for changes or to detect whether medications are working. Currently, physicians must use low-resolution scanners, which can only assess and diagnose the cause of...

Data travels through thousands of miles of fiber optic cables underneath the world’s oceans—via pulses of light. And according to experts, the data in these cables is at great risk of being intercepted. However, a newly designed frequency comb—recently developed...

A team of engineers from Germany has put on the table a method that would literally take those optical security measures to another dimension. Specifically, the research team—from the Karlsruher Institute Für Technologie (KIT) and Carl Zeiss AG—has demonstrated a...

Just imagine: An optical lens so powerful that it lets you view features the size of a small virus on the surface of a living cell in its natural environment. Construction of instruments with this capability is now possible because...

VTT Technical Research Centre of Finland has developed “Martti” – the first automated car to have driven itself fully autonomously on a real snow-covered road. The developers say their “robot car” has achieved a new speed record of 40 km/h...

This flat metalens is the first single lens that can focus the entire visible spectrum of light -- including white light -- in the same spot and in high resolution. It uses arrays of titanium dioxide nanofins to equally focus...

Autonomous vehicles need to monitor everything fixed or moving in their immediate environment. Next-gen lidar will play a vital role in achieving that comprehensive view....
