Investigating dense plasmas with positron waves
Astrophysical and lab-created plasmas under the influence of magnetic fields are the source of intense study. New research seeks to understand the dynamics of position waves traveling through these clouds of highly ionized gas......»»
Scientists have finally "heard" the chorus of gravitational waves that ripple through the universe
Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe......»»
Using a detector the size of a galaxy, astronomers detect gravitational waves from supermassive black hole pairs
When black holes and other enormously massive, dense objects whirl around one another, they send out ripples in space and time called gravitational waves. These waves are one of the few ways we have to study the enigmatic cosmic giants that create th.....»»
Astrophysicists propose a new way of measuring cosmic expansion: lensed gravitational waves
The universe is expanding; we've had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate......»»
The universe has a cosmic ‘hum’ caused by merging black holes
A 15-year study has provided more evidence of gravitational waves, including those at very low frequencies......»»
Heat waves like the one that"s killed 14 in the southern US are becoming more frequent and enduring
Heat waves like the one that engulfed parts of parts of the South and Midwest and killed more than a dozen people are becoming more common, and experts say the extreme weather events, which claim more lives than hurricanes and tornados, will likely i.....»»
At Last, There’s Evidence of Low-Frequency Gravitational Waves
A globe-spanning group of physicists used pulsars to measure the waves, which they believe emanated from pairs of supermassive black holes......»»
Investigating early land plant microfossils from the lower Silurian of southern Xinjiang, China
The Middle Ordovician-early Silurian is the key period for the origin and early evolution of morphological innovations of land plants. It is widely accepted that the earliest unambiguous fossil evidence of land plants can be traced to Dapingian-Darri.....»»
Clock-like precision of pulsars opens new window for studying gravitational waves
A team of European astronomers, along with Indian and Japanese colleagues, has reported evidence that strongly suggests the detection of ultra-low-frequency gravitational waves. Such waves, which have not previously been observed, probably originate.....»»
First Evidence of Giant Gravitational Waves Thrills Astronomers
Astrophysicists are tuning in to a never-before-seen type of gravitational waves spawned by pairs of supermassive black holes.....»»
The Universe Is Abuzz with Giant Gravitational Waves, and Scientists Just Heard Them (Maybe)
Researchers, using the galaxy as a detector, believe they have detected gravitational waves from monster black holes for the first time......»»
NANOGrav hears “hum” of gravitational wave background, louder than expected
Exotic stars called millisecond pulsars serve as celestial metronomes. Enlarge / In this artist’s interpretation, a pair of supermassive black holes (top left) emits gravitational waves that ripple through the fabric of space-t.....»»
Clamor of gravitational waves from universe"s merging supermassive black holes "heard" for first time
Following 15 years of data collection in a galaxy-sized experiment, scientists have "heard" the perpetual chorus of gravitational waves rippling through our universe for the first time—and it's louder than expected......»»
Scientists find key evidence for existence of nanohertz gravitational waves
A group of Chinese scientists has recently found key evidence for the existence of nanohertz gravitational waves, marking a new era in nanohertz gravitational wave research. The research was based on pulsar timing observations carried out with the Fi.....»»
Study using eDNA provides comprehensive picture of wildlife in southern California"s waves
What's living beneath the waves? It's a question many Southern California swimmers and surfers ponder when they visit the beach......»»
Novel algorithm improves understanding of plasma shock waves in space
Imagine the explosive disturbance caused by a jet going supersonic. A similar shock wave occurs when subatomic particles known as "solar wind" flow from the sun and strike the Earth's magnetic field. Now, scientists have used a recently developed tec.....»»
Hulu for iPhone fullscreen mode has been broken for nearly a month, many users say
Hulu users are growing increasingly frustrated with a long-running bug affecting the ability to watch content in fullscreen on iPhone. Hulu says that it has been investigating this bug for over a month; a fix hasn’t been released, but there is a t.....»»
Investigating the intricacies of auxin signaling mechanisms in algae
Phytohormones are chemical messengers that regulate the growth of plants and their response to the environment. In land plants, auxin is an important and well-studied phytohormone that affects various aspects of plant development......»»
Exploring how ocean dynamics affect transport of sargassum seaweed
With the waves inside the 49-foot-long Air-Sea Interaction Saltwater Tank (ASIST) looking like small ripples rushing to a shoreline, University of Miami doctoral student Katie Simi stood on a small step ladder and dropped a clump of sargassum seaweed.....»»
Germany to roll out measures against heat wave deaths, drawing lessons from France
The German government said Monday it is launching a campaign against deaths from heat waves that are becoming more frequent and intense due to climate change......»»
Study reveals genetic signatures of chickpea"s cultural crossroads
With its nutty flavor and dense nutrient profile, the humble chickpea has captivated palates and nourished civilizations for millennia. From its ancient origins to its widespread use in modern kitchens and restaurants around the world, this legume de.....»»
