Global convection-permitting model accurately predicts plum rain event
The plum rain is a persistent and extensive rainfall phenomenon that frequently occurs in East Asia during summer, primarily affecting regions along the latitudes of the middle and lower reaches of the Yangtze River in China to the Kyushu Island in J.....»»
Was "Snowball Earth" a global event? New study delivers best proof yet
Geologists have uncovered strong evidence from Colorado that massive glaciers covered Earth down to the equator hundreds of millions of years ago, transforming the planet into an icicle floating in space......»»
Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated period of over thr.....»»
Youth social media: Why proposed legislation won"t fix harms related to data exploitation
Ontario school board lawsuits against social media giants including Meta, Snapchat and TikTok are seeking damages— money paid as a remedy—for the disruption of the educational system......»»
How to build a home radio telescope to detect clouds of hydrogen in the Milky Way
If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or even an array of dish antennas such as the Very Large Array. What you likely don't imagine is something that resembles a TV dish in your neighbor's b.....»»
The Ars redesign is out. Experience its ad-free glory for just $25/year.
No better moment than now. Whew—the big event is finally behind us. I'm talking, of course, about the Ars Technica version 9 redesign, which we rolled out last month in response.....»»
New report details what happened to the Arecibo Observatory
In 1963, the Arecibo Observatory became operational on the island of Puerto Rico. Measuring 305 meters (~1000 ft) in diameter, Arecibo's spherical reflector dish was the largest radio telescope in the world at the time—a record it maintained until.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
Identity-related data breaches cost more than average incidents
Identity-related data breaches are more severe and costly than run-of-the-mill incidents, according to RSA. 40% of respondents reported an identity-related security breach. Of those, 66% reported it as a severe event that affected their organization......»»
Bach, Mozart or jazz: Scientists provide a quantitative measure of variability in music pieces
Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of dif.....»»
Pioneer, Elite, Onkyo, and Integra AV receivers get major update for Amazon Music, Tidal, and Dirac

Researchers uncover focal adhesions as subcellular signaling hubs in PI3K-AKT pathway
The phosphatidylinositol 3-kinase (PI3K)-AKT signaling pathway is one of the most critical and extensively investigated signaling pathways. It is the central regulator of various cellular processes including cell growth, proliferation, metabolism, an.....»»
Future space telescopes could be made from thin membranes, unrolled in space to enormous size
Space-based telescopes are remarkable. Their view isn't obscured by the weather in our atmosphere, and so they can capture incredibly detailed images of the heavens. Unfortunately, they are quite limited in mirror size......»»
Successful demonstration of a commercial cryogenic radio frequency power sensor paves way for quantum computing
Radio frequency (RF) and microwave power measurements are widely used to support applications across space, defense, and communication. These precise measurements enable engineers to accurately characterize waveforms, components, circuits, and system.....»»
