Acoustic propulsion of nanomachines depends on their orientation
Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, bec.....»»
Hera asteroid mission completes acoustic testing
ESA's Hera asteroid mission has completed acoustic testing, confirming the spacecraft can withstand the sound of its own lift-off into orbit. Testing took place within the Agency's Large European Acoustic Facility at the ESTEC Test Center in the Neth.....»»
Researchers realize water-air acoustic communication based on broadband impedance matching
With increasing demand for exploration and utilization of marine resources, achieving direct and efficient communication between water and air has been an urgent need. Sound waves, as the only propagation way with low attenuation in both water and ai.....»»

Apple’s new macOS Sonoma 14.1.1 update could take a long time to download and install on your Mac. The amount of time depends on your Mac model and the version of macOS it’s currently running. macOS Sonoma 14.1.1 is available to download right no.....»»
Arctic Ocean soundscapes reveal changes in mammal populations in response to climate change
While the sounds of our oceans may be familiar to us through the lens of nature documentaries, from the haunting calls of whales to the barks of some fish, this acoustic environment can provide a wealth of knowledge to scientists regarding the comple.....»»
Saturday Citations: Moon origins, rat whimsy, microgravity orientation. Plus: Starfish are bodiless heads, it turns out
Good morrow and a cheerful week's end to you. This week, we reported on notable developments in the lack of starfish body development. Physicists used a new method to revisit the planetary collision that likely formed the moon and might have found ch.....»»
In person or online? Researchers find people"s stated support for democracy depends on how they"re asked
Americans may be less satisfied with U.S. democracy than previously thought and new survey methods may have something to do with that disconnect, according to researchers at Georgia State University......»»

Hubble captures spiral galaxy IC 5332 face-on
This glittering image from the NASA/ESA Hubble Space Telescope shows the spiral galaxy IC 5332. The galaxy lies about 30 million light-years away in the constellation Sculptor and has an almost face-on orientation to Earth. To understand the term "fa.....»»
A strategy for the spin-acoustic control of silicon vacancies in a 4H silicon carbide-based bulk acoustic resonator
Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's RF telecommunication, like Front-End Modules (F.....»»
Measuring the changing soundscape in Glacier National Park
From the eerie echo of a bugling elk to the gentle swoosh of water lapping against a stony shore, a unique combination of sounds helps distinguish each national park. This acoustic environment, as perceived by humans, is known as a soundscape, and it.....»»

Participation in climate protests partly depends on expected size, study finds
Whether or not people choose to attend a climate protest partly depends on its expected size. When they expect a larger protest, they are less likely to take part—as Universität Hamburg's Cluster of Excellence for climate research (CLICCS) shows i.....»»
Net neutrality’s court fate depends on whether broadband is “telecommunications”
We dig deep into how Supreme Court's "major questions doctrine" could affect FCC. Enlarge / FCC Chairwoman Jessica Rosenworcel speaks during the US Chamber of Commerce's Global Aerospace Summit in Washington, DC, on Wednesday, Se.....»»
Researchers realize orientation control of cMOF nanofilms
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Kyoto University have proposed a strategy to grow "face-on" and "edge-on" conductive metal-organic frameworks (cMOF) nanofilms on substrates by control.....»»
How much are you willing to pay for a product or service? It depends on your other options and the given context
Researchers from Concordia University and Northwestern University published a new Journal of Marketing study that presents the Comparative Method of Valuation as a more accurate way to measure customers' willingness to pay for a product or service......»»
Understanding the single cell proteome in the context of surrounding tissue
Similar to humans and animals, which adapt their diet or behavior to given environmental conditions, the function and protein composition of single cells also depends on which resources are available in their immediate environment......»»
