New epoch of miniaturized Cherenkov detectors
Recently, the research team led by Prof. Yu Luo from the school of Electrical and Electronic Engineering, Nanyang Technological University, discovered surface Dyakonov-Cherenkov radiation. This new type of Cherenkov radiation not only presages the ne.....»»
Black hole "carnivals" may produce the signals seen by gravitational-wave detectors
Since 2015, the LIGO-Virgo-KAGRA Collaboration have detected about 85 pairs of black holes crashing into each other. We now know that Einstein was right: gravitational waves are generated by these systems as they inspiral around each other, distortin.....»»
First "Run 3" physics result from the Large Hadron Collider"s compact muon solenoid
On July 5, the LHC roared to life for its third run after three years of continual improvements to the machine as well as to the experiments' detectors and analysis tools, and immediately reached a record energy of 13.6 TeV. Just three weeks later, t.....»»
Integration on a chip: Miniaturized infrared detectors

Developing strategies for high-quality crystal growth
Transition metal dichalcogenides (TMDCs) are a class of materials with physical properties that make them ideally suited for use in flexible optoelectronic applications, such as light detectors, light-emitting diodes and solar cells. For such applica.....»»
NASA"s Roman mission delivers detectors to Japan"s PRIME Telescope
Billy Keim, a NASA technician, removes a 16-megapixel detector from its shipping container internal fixture as engineer Stephanie Cheung coordinates the activity. NASA's future Nancy Grace Roman Space Telescope will be fitted with 18 of these infrare.....»»
Researchers fabricate miniaturized bionic ocean-battery
The researchers from the Institute of Microbiology of the Chinese Academy of Sciences have developed a miniaturized bionic ocean-battery, a bio-solar cell that converts light into electricity, by mimicking the basic ecological structure of marine mic.....»»
Fiber-optic sensing probe: Quasi-3D plasmonic structures on fiber tips
Miniaturized sensors mounted upon optical fibers are widely recognized as an important future solution to instant and point-of-care medical diagnosis and on-site agricultural produce inspection. Plasmonic devices on the flat end-facets of single-mode.....»»
ESA astronaut rad-detectors on Artemis
Next Monday's Artemis launch will be an uncrewed first flight, headed into orbit around the moon. Yet technology previously worn by ESA astronauts on the International Space Station has also been hard-mounted aboard the NASA-ESA Orion module......»»
NASA"s PUNCH mission announces rideshare with SPHEREx and new launch date
NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will share a ride to space with NASA's Jet Propulsion Laboratory's Spectro-Photometer for the History of the Universe, Epoch of Re-ionization, and Ices Explorer (SPHEREx) mission......»»
Ultrasonic detectors reveal the detrimental effect of wind turbines on bats
As more and more wind turbines (WTs) are installed in the course of the energy transition and distance regulations to human settlements are tightened, suitable locations are becoming increasingly difficult to find. As a result, wind turbines are incr.....»»
Ars dives into the pricey-but-fancy world of miniature arcade cabinets
We put 1/6-scale cabs from New Wave Toys and their tiny joysticks to the test. Enlarge / 20 oz. soda bottle for scale. (credit: Sam Machkovech) The category of miniaturized classic arcade cabinets has exploded in recent years,.....»»
Bomb detectors picking up more blue whale songs in Indian Ocean
The good news is pygmy blue whales appear to be thriving in the Indian Ocean. The not-so-good news is that climate change may be threatening their food sources......»»
Miniaturized, highly sensitive ultrasound sensor for photoacoustic imaging
Photoacoustic imaging generates ultrasound waves by irradiating biological tissues with pulses or modulated continuous lasers. Ultrasound sensors are used to capture ultrasound signals in a distributed manner. Then, the light absorption distribution.....»»
You Can Run Doom on a Chip From a $15 Ikea Smart Lamp
A $14.95 smart lamp from Ikea apparently has enough computing power to run the classic PC game Doom. From a report: A software engineer named Nicola Wrachien removed the smart lamp's computer chip and used it to build a miniaturized Doom gaming syste.....»»
Phonon dynamics enable a deeper understanding of how heat travels through quantum dots
As electronic, thermoelectric and computer technologies have been miniaturized to nanometer scale, engineers have faced a challenge studying fundamental properties of the materials involved; in many cases, targets are too small to be observed with op.....»»
Researchers pinpoint the end of "cosmic dawn," the epoch of reionization
A group of astronomers led by Sarah Bosman from the Max Planck Institute for Astronomy have robustly timed the end of the epoch of reionization of the neutral hydrogen gas to about 1.1 billion years after the Big Bang. Reionization began when the fir.....»»
Afraid your pipes will burst? Here are the top water leak detectors
Worried about leaks or flooding on your property? These water leak detectors will sense leaks and send you alerts or sirens to warn you about possible damage......»»
One step closer to making terahertz technology usable in the real world
Researchers have discovered in two-dimensional conductive systems a new effect that promises improved performance of terahertz detectors......»»
Almost ready for prime time: Deep UV photodetectors head to real-world testing
