Shock waves in outflow gases could regulate "volcano lightning"
Volcanic eruptions spew lava, rock and ash into the air. When fragments of these materials mix and collide in the outflow, they can create an electric potential large enough to generate lightning......»»
New study simulates gravitational waves from failing warp drive
Imagine a spaceship driven not by engines, but by compressing the spacetime in front of it. That's the realm of science fiction, right? Well, not entirely. Physicists have been exploring the theoretical possibility of "warp drives" for decades, and a.....»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
3D models show dolphins already used narrow-band sound waves for orientation 5 million years ago
Senckenberg researcher Dr. Rachel Racicot and her former student Joyce Sanks from Vanderbilt University have examined the inner ear of the extinct dolphin genus Parapontoporia. In their study, published in the journal The Anatomical Record, they show.....»»
New study disputes Hunga Tonga volcano"s role in 2023–24 global warm-up
New research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the proc.....»»
Humanity suffering from "extreme heat epidemic," UN chief warns
Humanity is suffering from an "extreme heat epidemic," UN Secretary-General Antonio Guterres warned Thursday, calling for action to limit the impacts of heat waves intensified by climate change......»»
Mexico tries to bring drought-stricken lake back to life
Mexican authorities are releasing thousands of juvenile fish and cleaning up freshwater springs as part of efforts to rejuvenate one of the country's lakes stricken by drought and heat waves......»»
Early riser: The sun is already starting its next solar cycle—despite being halfway through its current one
The first rumblings of the sun's next 11-year solar cycle have been detected in sound waves inside our home star—even though it is only halfway through its current one......»»
Elephants and big waves are subjects of inbound Immersive Video releases
Apple has brought out more Immersive Video content for the Apple Vision Pro, with series and films putting the viewer in the middle of the action.Elephants from the Apple Immersive Video series 'Wild Life'Apple Immersive Video has been a big draw for.....»»
Studies find China-based emissions of three potent climate-warming greenhouse gases have spiked in past decade
When it comes to heating up the planet, not all greenhouse gases are created equal. They vary widely in their global warming potential (GWP), a measure of how much infrared thermal radiation a greenhouse gas would absorb over a given time frame once.....»»
"It"s unbearable": heat waves scorch southern and eastern Europe
Unrelenting heat is blanketing swathes of southern and eastern Europe, with dozens of cities on red alert as scorching temperatures fuel wildfires, strain power grids, and make daily life unbearable......»»
Tool predicts rogue waves up to five minutes in advance
A new tool that can be used to predict the emergence of unusually large and unpredictable waves at sea—known as rogue waves—up to five minutes into the future is presented in a study published in Scientific Reports. The authors suggest that the t.....»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
An international team led by scientists at City University of Hong Kong has found a flexible metal-organic framework (MOF) with one-dimensional channels that acts as a "molecular trapdoor" to selectively adsorb gases, such as carbon dioxide, in respo.....»»
Study identifies RNA molecule that regulates cellular aging
A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditio.....»»
Attributing Canada"s June heat wave to climate change is an important step in adapting to a warmer world
This June saw major heat waves across Canada with peak temperatures—measured over a three-day period—of 7.4°C in eastern Ontario, 10.7°C in southern Québec, 7.2°C in northern Québec and 10.6°C in Atlantic Canada. On June 19, more than 100 l.....»»
Tesla Cybertruck beats Ford F-150 Lightning as top electric pickup in latest registration data
The Cybertruck's numbers were strong enough to propel it to fifth place among all battery-electric vehicles for May, S&P Global Mobility said. The F-150 Lightning was No. 10 among all EVs......»»
Irish peat soils are far more vast than previously known, suggests study
New figures suggest peat soils cover 13% more area than previous peat soil maps, which are useful in land use planning—with peat soils critical in absorbing greenhouse gases (GHG) and helping to meet some of Ireland's most pressing environmental ch.....»»
Climate change threatens overall firefly populations, study shows, but Midwest could see increase
For many who grew up east of the Mississippi River, yellow twinkling lights punctuate magical childhood memories. New England natives call them fireflies, but they're known as lightning bugs from the Midwest to the South. No matter their regional nam.....»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»
Amid a sweltering summer, a new study finds street trees thrive in NYC
So far this summer, New York City—like much of the country—has clocked more than 11 90-plus degree days. In addition to the increasing frequency of extreme heat waves, if it seems hotter in the city than in other environments, it typically is......»»
AI model harnesses physics to autocorrect remote sensing data
Turbulence, temperature changes, water vapor, carbon dioxide, ozone, methane, and other gases absorb, reflect, and scatter sunlight as it passes through the atmosphere, bounces off the Earth's surface, and is collected by a sensor on a remote sensing.....»»
