Some frogs have noise-cancelling lungs to dampen other species’ calls

To better hear a male’s mating call, some female frogs have noise-cancelling lungs, which resonate at frequencies that filter out the sounds of other species Source: https://www.newscientist.com/article/2270131-some-frogs-have-noise-cancelling-lungs-to-dampen-other-species-calls/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Dolphins that help humans catch fish are being disturbed by ship noise

Some dolphins help humans catch fish, but an uptick in the levels of noise pollution from nearby ships is changing the way the dolphins communicate with one another Source: https://www.newscientist.com/article/2269425-dolphins-that-help-humans-catch-fish-are-being-disturbed-by-ship-noise/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Quantum Computer Solves Decades-Old Problem Three Million Times Faster Than a Classical Computer

ZDNet reports: Scientists from quantum computing company D-Wave have demonstrated that, using a method called quantum annealing, they could simulate some materials up to three million times faster than it would take with corresponding classical methods. Together with researchers from Google, the scientists set out to measure the speed of simulation in one of D-Wave’s quantum annealing processors, and found that…

Male lyrebirds imitate a flock of birds to scare females into mating

Birds threatened by a predator often call out to encourage other birds to make noise and fly about, repelling the attacker as part of a “mobbing flock”. Now it seems male lyrebirds imitate this sound to scare females into mating Source: https://www.newscientist.com/article/2269303-male-lyrebirds-imitate-a-flock-of-birds-to-scare-females-into-mating/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Quantum effects help minimize communication flaws

Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences, under the lead of Philip Walther, reveals novel techniques to reduce noise in quantum communication. The results, published in the latest issue…

‘Major Component Malfunction’ Ends SLS Rocket Test Early. NASA Considers New Timeline

“NASA’s rocket charged with taking the agency back to the moon fired its four main engines Saturday afternoon, but the test in Mississippi was cut short after a malfunction caused an automatic abort,” reports Florida Today… “We did get an MCF on engine four,” a control room member said less than a minute into the test fire, using an initialism that…

Watch NASA Test-Fire Its SLS Mega-Rocket Engines

“The date is set,” NASA tweeted yesterday, thanking its partners Boeing Space and Aerojet Rocketdyne for Saturday’s “hot fire” test of the SLS’s core stage. “One of NASA’s main goals for 2021 is to launch Artemis I, an uncrewed moon mission meant to show the Orion spacecraft and Space Launch System rocket can safely send humans to our lunar neighbor,” reports…

Wind farm construction creates noise that may harm squid fisheries

The noisy construction of offshore wind turbines can discourage squid from hunting, which could lead to decreased squid populations and potentially decrease profits at fisheries Source: https://www.newscientist.com/article/2264740-wind-farm-construction-creates-noise-that-may-harm-squid-fisheries/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Dell’s New Monitors Have a Dedicated Microsoft Teams Button

Dell is launching three new monitors next month, and all of them come with a dedicated Microsoft Teams button. The Verge reports: Dell claims it has created the “world’s first video conferencing monitors certified for Microsoft Teams,” after Microsoft started certifying displays, webcams, and headsets last year. Three monitors will be available next month, all offering quick access to Microsoft Teams….
