Seeing with radio waves
Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called 'spin-locking' to significantly enhance the resolution when performing radio-frequency imaging of nitrogen-vacancy defects in diamond. This work may l.....»»
Using photos to create 3D models helps us understand, and protect, complex marine environments
Measuring the impact of different events, such as marine heat waves, on the abundance of marine organisms is not easy. Biological communities naturally change over time and between different locations......»»
Giant waves flood key US military base on Marshall Islands
A clean-up operation was underway Thursday after giant waves flooded a key US military base on the Marshall Islands in the heart of the South Pacific......»»
"In the Know" review: Stop-motion satire from Mike Judge and Zach Woods
"King of the Hill" creator Mike Judge's stop-motion sitcom "In the Know" introduces a fictional NPR show and its kooky team. If you were to listen to In the Know, the fake radio show at the heart of Peacock's new sitcom of the same name, you wo.....»»
Overcoming optical loss in a polariton system with synthetic complex frequency waves
A collaborative research team co-led by Professor Shuang Zhang, the Interim Head of the Department of Physics, The University of Hong Kong (HKU), along with Professor Qing DAI from National Center for Nanoscience and Technology, China, has introduced.....»»
Marine heat waves found to trigger shift in hatch dates and early growth of Pacific cod
Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study from Oregon State University shows......»»
New carbon-based tunable metasurface absorber paves the way for advanced terahertz technology
Working in the terahertz (THz) range offers unique opportunities in various applications, including biomedical imaging, telecommunications, and advanced sensing systems. However, because of the unique properties of electromagnetic waves in the 0.1 to.....»»
Not all underwater reefs are made of coral—the US has created artificial reefs from sunken ships, radio towers and more
When people hear about underwater reefs, they usually picture colorful gardens created from coral. But some reefs are anchored to much more unusual foundations......»»
Reaching the quantum ground state of sound in waveguides: Scientists move a step closer
A team of scientists at the Max Planck Institute for the Science of Light led by Dr. Birgit Stiller has succeeded in cooling traveling sound waves in waveguides considerably further than has previously been possible using laser light. This achievemen.....»»
Engineers develop terahertz imaging system capable of capturing real-time, 3D multi-spectral images
Terahertz waves can penetrate opaque materials and provide unique spectral signatures of various chemicals, but their adoption for real-world applications has been limited by the slow speed, large size, high cost and complexity of terahertz imaging s.....»»
Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
Marine heat waves affecting little penguin population
Research led by The University of Western Australia has found marine heat waves are affecting the breeding, diet and population size of little penguins along Western Australia's coast......»»
Researchers visualize energetic ion flow in fusion devices
In a burning plasma, maintaining confinement of fusion-produced energetic ions is essential to producing energy. These fusion plasmas host a wide array of electromagnetic waves that can push energetic ions out of the plasma......»»
Astronomers produce most sensitive radio image ever of ancient star cluster
A global team of astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly packed stars......»»
Gravitational waves could show us the first minute of the universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagneti.....»»

What is Auracast? The Bluetooth broadcast standard fully explained
With Auracast, your Bluetooth headphones are going to be a lot more useful, and your phone can act as a personal radio station. Here's what you need to know......»»
New paper explores four nearby fast radio burst sources
Fleeting blasts of energy from space, known as fast radio bursts (FRBs), are a cosmic enigma. A Canadian-led international team of researchers has published new findings suggesting that supernovae are the predominant contributors to forming sources t.....»»
Astronomers think they finally know origin of enormous “cosmic smoke rings“
Massive stars burn out quickly. When they die, they expel their gas as outflowing winds. Enlarge / Odd radio circles are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (c.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Hurricane waves hitting Americas grow 20% per decade: Study
The U.S., Mexico and countries in the Caribbean are being battered by hurricane-induced ocean waves that have grown in areal size by 80% over the past 40 years, a new study has found......»»
