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.....»»
Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
Astronomers comb telescope archive and find microsecond-duration burst
An international team of researchers led by Dutch Ph.D. candidate Mark Snelders (ASTRON and University of Amsterdam) has discovered radio pulses from the distant universe that last only millionths of a second. They found these microsecond bursts afte.....»»
Going rogue: Scientists apply giant wave mechanics on a nanometric scale
Researchers have shown how the principles of rogue waves—huge 30-meter waves that arise unexpectedly in the ocean—can be applied on a nano scale, with dozens of applications from medicine to manufacturing......»»
Physicists create new form of antenna for radio waves
University of Otago physicists have used a small glass bulb containing an atomic vapor to demonstrate a new form of antenna for radio waves. The bulb was "wired up" with laser beams and could therefore be placed far from any receiver electronics......»»
Reef-devouring predator survives coral bleaching and feasts on the survivors
Research conducted by marine biologists from the University of Sydney has found juvenile crown-of-thorns starfish can withstand tremendous heat waves well above levels that kill coral. These starfish then develop into carnivorous predators that devou.....»»
Cracking the code of 2022"s unprecedented heat waves and droughts
Extreme weather events have been making headlines worldwide due to their increasing frequency and severity, often attributed to ongoing global-scale warming. The year 2022 was no exception, with record-breaking heat waves and droughts of highly unusu.....»»

Zyxel Networks introduces 22Gbps WiFi 7 access point for MSPs and SMBs
Zyxel Networks launched its first WiFi 7 access point for managed service providers (MSPs) and small- to medium-sized businesses (SMBs). Zyxel’s WBE660S WiFi 7 BE22000 Triple-Radio NebulaFlex Pro Access Point provides enterprise-grade technology, e.....»»
Saturday Citations: Gravitational waves, time travel and the simulated universe hypothesis
This week, researchers proved empirically that life isn't fair. Also, you'll notice that, in a superhuman display of restraint, I managed to write a paragraph about the simulated universe hypothesis without once referencing "The Matrix." (Except for.....»»
New research can help better predict the health and sustainability of "grassy" ecosystems
Newly published research from UNC Greensboro's Dr. Kevin Wilcox and colleagues will help scientists better predict how global changes—such as droughts, fires, and heat waves—will impact the health and sustainability of the Earth's grassy ecosyste.....»»
French government leaks late October release date for iOS 17.1
France's radiation watchdog has leaked the impending release of iOS 17.1 by October 24, with fixes that will end the iPhone 12 radio frequency exposure controversy and potential recall threat.The entire iPhone 12 lineupAs noted by iPhoneSoft, the Age.....»»
Phonon engineering for extended lasing beyond the fluorescence spectrum
The electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polaritons, charge density waves and up-conversion fluorescence.....»»
Quantum Physics Isn"t as Weird as You Think. It"s Weirder
Quantum physics’ oddities seem less surprising if you stop thinking of atoms as tennis balls, and instead more like waves pushing through water.....»»
