Elegantly modeling Earth"s abrupt glacial transitions
Proxy data—indirect records of the Earth's climate found in unlikely places like coral, pollen, trees and sediments—show interesting oscillations approximately every 100,000 years starting about one million years ago. Strong changes in global ice.....»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
China"s "Thousand Sails" joins Starlink as the latest mega-satellite constellation in orbit
With "Thousand Sails," China joins the race to fill up Low Earth Orbit with mega-satellite constellations......»»
Modeling study shows that marshes provide cost-effective coastal protection
Images of coastal houses being carried off into the sea due to eroding coastlines and powerful storm surges are becoming more commonplace as climate change brings a rising sea level coupled with more powerful storms. In the U.S. alone, coastal storms.....»»
Ethical framework aims to counter risks of geoengineering research
As interest grows in geoengineering as a strategy for tackling global warming, the world's largest association of Earth and space scientists has launched an ethical framework as a guide to responsible decision-making and inclusive dialogue......»»

Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
Shear waves split into fast and slow waves when they travel through elastically anisotropic media, and the anisotropy of the seismic velocity is recorded by seismic stations. In the Earth's deep interior, this is usually interpreted as the effect of.....»»
May 2024 super geomagnetic storm challenges current space weather prediction models
During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae as far south as the Canary.....»»
New ice core data provide insight into climate "tipping points" during the last Ice Age
A changing climate triggers a sudden shift in ocean circulation, creating weather havoc and plunging Earth into an abrupt new Ice Age......»»
Photosynthesis is under threat in an increasingly warm world, says researcher
The basis of all life on Earth is photosynthesis. So, what happens if it is disrupted? Today, advanced measurement tools can reveal how climate change is affecting plants' ability to process the energy from sunlight......»»
Modeling experiments show weather-changing El Niño oscillation is at least 250 million years old
The El Niño event, a huge blob of warm ocean water in the tropical Pacific Ocean that can change rainfall patterns around the globe, isn't just a modern phenomenon......»»
Giant meteorite impact 3.26 billion years ago may have aided early life
Billions of years ago, long before anything resembling life as we know it existed, meteorites frequently pummeled the planet. One such space rock crashed down about 3.26 billion years ago, and even today, it's revealing secrets about Earth's past......»»
3D structures of biomolecules: "Dictionaries" make fluorescence-based data accessible
A research team from Germany and the U.S. led by Heinrich Heine University Düsseldorf (HHU) has developed a data description that can provide results from fluorescence measurements for structural and dynamic modeling of large biomolecules......»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»
Scientists update eruption history of Oregon"s South Sister volcano
A hiker's pack usually gets lighter over time as they plow through trail mix and water, but Annika Dechert likes to joke that hers gets heavier. As an Earth sciences graduate student at the University of Oregon, she's picking up clues to the eruption.....»»
Departing ISS astronaut still finds time for stunning night shot
NASA astronaut Matthew Dominick is grabbing some last-minute Earth shots from the ISS as he prepares to fly home after more than seven months in orbit......»»
Saturday Citations: Brown dwarf actually brown dwarfs; the adaptability of ice-age humans; archaeologists excited
This week, researchers discovered a near-Earth microquasar that sheds new light on sources of relativistic outflows. Doctors reported finding a triphallic gentleman. And neuroscientists reported on modest cognitive boosts from short (or "acute," in c.....»»
New research shows most space rocks crashing into Earth come from a single source
The sight of a fireball streaking across the sky brings wonder and excitement to children and adults alike. It's a reminder that Earth is part of a much larger and incredibly dynamic system......»»
Lignin molecular property discovery could help turn trees into affordable, greener industrial chemicals
Trees are the most abundant natural resource living on Earth's land masses, and North Carolina State University scientists and engineers are making headway in finding ways to use them as sustainable, environmentally benign alternatives to producing i.....»»
Could injecting diamond dust into the atmosphere help cool the planet?
A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet. In their study published in the journal Geophysical Research L.....»»
