Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless communication they have primarily focused on until now. This opened up a new wireless channel for confirming the survival of buried people in the event of a collapse of an underground facility such as a mine, conducting underground rescue operations […]
MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the “cocktail party problem.” This attentional focus becomes necessary when you’re in any crowded environment, such as a cocktail party, with many conversations going […]
University of Houston professor of psychology Arturo Hernandez is disputing a high-profile study claiming that people who live in multilingual countries show healthier brain aging. Though the study got lots of attention, Hernandez and collaborators report that the findings warrant cautious interpretation and reframing of public health implications. “We took a closer look and argued […]
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a sheet of paper. But quantum physics tells a different story. In reality, nature resists rigidity and forces even the simplest structures into the […]
For decades, scientists have searched the skies for signs of extraterrestrial technology, contacts. A study from EPFL asks a sharp question: if signals from technological aliens have already reached Earth without us noticing, what should we realistically expect to detect today? Since the first SETI experiment in 1960, astronomers have scanned the Milky Way for […]
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That’s harder than it sounds. Memory storage, information processing, and energy use in these technologies involve constant energy flow—systems never settle into thermodynamic balance. To complicate things further, one of the most precise ways to study […]
A Univerity of Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed long before Earth existed. Linda Losurdo, a Ph.D. candidate in materials and plasma physics […]
Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets. The findings, using new data from NASA’s James Webb Space Telescope (Webb) tells us more about how this invisible substance helped pull ordinary matter into galaxies like the Milky […]
Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery. The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter Array (ALMA), has produced the sharpest images ever of 24 debris disks, the dusty belts left after planets finish forming. These […]
Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving an “icehouse climate” that, together with radically changed ocean chemistry, ultimately caused the extinction of about 85% of […]
