New type of bolometer detector for far-infrared telescopes
To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as the detectors, despite thei.....»»

Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication......»»
Information overload is a personal and societal danger, researchers say
We are all aware of the dangers of pollution to our air, water, and Earth. In a letter recently published in Nature Human Behavior, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equ.....»»

Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
Opinion: Lagos bans single-use plastics—why I think Nigeria should have taxed them instead
Waste pollution is a huge problem in Nigeria, with serious impacts on the environment. In response, the Lagos state government has banned styrofoam (a type of plastic widely used as food containers) and other single-use products......»»
Ultrablack thin-film coating could make next-gen telescopes even better
Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes and optical systems, every.....»»

"Molecular Rosetta Stone" reveals how our microbiomes "talk" to us
Researchers from Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California San Diego have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of.....»»
Webb peers into the tendrils of NGC 604
Two new images from the NASA/ESA/CSA James Webb Space Telescope's NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) showcase the star-forming region NGC 604, located in the Triangulum galaxy (M33), 2.73 million light-years away from Ea.....»»
Webb and Hubble telescopes affirm the universe"s expansion rate, but the puzzle persists
The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos......»»
New type of tunable filter reveals the potential for terahertz wireless communications
Electromagnetic waves in the terahertz frequency range offer many advantages for communications and advanced applications in scanning and imaging, but realizing their potential poses challenges. Researchers at Tohoku University have addressed one of.....»»
