Electricity can be streamed wirelessly across a room through thin air, researchers have found.

Scientists from Seoul, South Korea, have figured out how to transmit 400 milliwatts (mW) of electricity over nearly 100 feet using infrared laser light, according to research published in the journal Optics Express.

“The ability to power devices wirelessly could eliminate the need to carry around power cables for our phones or tablets,” research team leader Jinyong Ha from Sejong University in South Korea said in a statement. “It could also power various sensors such as those used for monitoring processes in manufacturing plants.”

The properties of nanoribbon edges are important for their applications in electronic devices, sensors, and catalysts. A group of scientists from Japan and China studied the mechanical response of single-layer molybdenum disulfide nanoribbons with armchair edges using in situ transmission electron microscopy.

They showed that the Young’s modulus varied inversely with its width below the width of 3nm, indicating a higher bond stiffness for the armchair edges. Their work, published in the journal Advanced Science, was co-authored by Associate Professor Kenta Hongo and Professor Ryo Maezono from JAIST and Lecturer Chunmeng Liu and Lecturer Jiaqi Zhang from Zhengzhou University, China.

Sensors have become ubiquitous in the , with applications ranging from detecting explosives, measuring physiological spikes of glucose or cortisol non-invasively to estimating greenhouse gas levels in the atmosphere.

“Our camera uses a completely new method to achieve high-speed imaging. It has an imaging speed and spatial resolution similar to commercial high-speed cameras but uses off-the-shelf components.”

Scientists from the Institut National De La Recherche Scientifique (INRS) in Canada, in collaboration with Concordia University and Meta Platforms Inc., unveiled a game-changing camera that could revolutionize high-speed imaging.

The diffraction-gated real-time ultrahigh-speed mapping (DRUM) camera, introduced in a recent paper published in Optica, is poised to democratize ultrafast imaging, making it accessible for a wide range of applications.

When it comes to preserving profit margins, data scientists for vehicle and parts manufacturers are sitting in the driver’s seat.

Viaduct, which develops models for time-series inference, is helping enterprises harvest failure insights from the data captured on today’s connected cars. It does so by tapping into sensor data and making correlations.

The four-year-old startup, based in Menlo Park, Calif., offers a platform to detect anomalous patterns, track issues, and deploy failure predictions. This enables automakers and parts suppliers to get in front of problems with real-time data to reduce warranty claims, recalls and defects, said David Hallac, the founder and CEO of Viaduct.

Researchers at Karolinska Institute have developed a novel method using DNA nanoballs to detect pathogens, aiming to simplify nucleic acid testing and revolutionize pathogen detection. The study’s results, published in Science Advances, could pave the way for a straightforward electronic-based test capable of identifying various nucleic acids in diverse scenarios quickly and cheaply.

Principal investigator Vicent Pelechano, an associate professor at Karolinska Institute’s Department of Microbiology, Tumor and Cell Biology, is cautiously optimistic about the technology’s potential to detect an array of pathogenic agents in real world settings.

“The methodology involves combining Molecular Biology (DNA nanoball generation) and electronics (electric impedance-based quantification) to yield a pioneering detection tool,” says Vicent Pelechano.

Scientists with the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers said the method demonstrates great promise; the dots are already as efficient as existing conventional methods, even though the experiments are still in early stages.

The dots could someday form the basis of infrared lasers as well as small and cost-effective sensors, such as those used in exhaust emissions tests or breathalyzers.

“Right now the performance for these dots is close to existing commercial sources, and we have reason to believe we could significantly improve that,” said Philippe Guyot-Sionnest, a professor of physics and chemistry at the University of Chicago, member of the James Frank Institute, and one of three authors on the paper published in Nature Photonics. “We’re very excited for the possibilities.”
