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.....»»

Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
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.....»»
Hubble captures intricacies of R Aquarii, a symbiotic binary star roughly 700 light-years from Earth
The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble's images capture its details and its evolution is featur.....»»
Space Force"s X-37B will perform "never before-seen maneuvers" in orbit
The X-37B Orbital Test Vehicle (OTV) has been shrouded in mystery since its maiden flight in 2011. Designed by Boeing and operated by the U.S. Space Force (USSF), this remotely operated, reusable space plane is designed to operate in Low-Earth Orbit.....»»

El Niño Southern Oscillation caused spike in 2023 temperatures, study finds
A study by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science identified El Niño–Southern Oscillation as the primary cause of the spike in global surface temperature in 2023, not human-induced climate.....»»
Modern mass extinction in an Ecuadorean cloud forest found to be a mirage
One of the most notorious mass extinction events in modern times occurred on a hilltop in coastal Ecuador in the 1980s. Ninety species of plants known from nowhere else on Earth—many of them new to science and not yet given a name—went extinct wh.....»»
Penetrating the ice sheet of an ocean moon: Four questions about the Clipper Mission to Europa
On Oct. 14 NASA's Europa Clipper Mission launched. It is the first detailed investigation of Jupiter's moon Europa—which is believed to harbor an ocean so vast that it contains more water than anywhere else in the known universe (even Earth). While.....»»
State backs environmentalists after water shutoff kills thousands of fish in Kern River
