What did the snowball Earth look like?
Entire continents, even in the tropics, seems to have been under sheets of ice. By now, it has been firmly established that the Earth went through a series of global glaciations a.....»»
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......»»
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......»»
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.....»»

MAX phases boost electrocatalytic biomass upgrading
Biomass is among the most abundant renewable resources on Earth. Through catalytic conversion, biomass can upgrade into a series of fuels and chemicals which can substitute traditional fossil resources, thus playing a crucial role in achieving the "c.....»»
A near-Earth microquasar emerges as a source of powerful radiation
Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of active galaxies distant from Earth. However, a dif.....»»
Old data yield new secrets as NASA"s DAVINCI preps for Venus trip
Due to launch in the early 2030s, NASA's DAVINCI mission will investigate whether Venus—a sweltering world wrapped in an atmosphere of noxious gases—once had oceans and continents like Earth......»»
A new generation of telescopes will probe the "unknown unknowns" that could transform our knowledge of the universe
In recent decades, we've learned huge amounts about the universe and its history. The rapidly developing technology of telescopes—both on Earth and in space—has been a key part of this process, and those that are due to start operating over the n.....»»
Ancient ‘Age of Dinosaurs’ Seafloor Found beneath Pacific Ocean
A vast, ancient slab of seafloor plunged beneath the Pacific Ocean and has hovered in Earth’s mantle for more than 120 million years, a new study suggests.....»»
Six new Copernicus missions to provide detailed environmental data
The Copernicus Sentinel Expansion Missions are a major leap forward in Europe's Earth observation capabilities. With the United Kingdom's re-entry to the EU's Copernicus program, funding has been confirmed to complete the development of all six Coper.....»»
Plate tectonics drive compositional evolution of the upper mantle, study finds
On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, when did global chemical heterogeneity of the conv.....»»
