Saltier Oceans Could Have Prevented Earth From Freezing
The Sun shone 20% less brightly on early Earth, and yet fossil evidence shows that our planet had warm shallow seas where stromatolites -- microbial mats -- thrived. Now a study may have solved the "faint young Sun paradox," showing that saltier ocea.....»»
Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»

Ancient viral genomes preserved in glaciers reveal climate history—and how viruses adapt to climate change
As humans alter the planet's climate and ecosystems, scientists are looking to Earth's history to help predict what may unfold from climate change. To this end, massive ice structures like glaciers serve as nature's freezers, archiving detailed recor.....»»
Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed
When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It's also bad for human populations that rely on fish for protein in their diets......»»
Scientists Plan ‘Doomsday’ Vault on Moon
Climate change is threatening Earth’s biodiversity. Could frozen regions of the moon be the best place to “back up” life-forms?.....»»
A Rare Coincidence of La Niña Events Will Weaken Hurricane Season
The oceans have produced a rare coincidence of the Pacific and Atlantic Niñas, which will lessen the severity of the hurricane season—though 2024 still remains a highly active year......»»
Boeing will try to fly its troubled Starliner capsule back to Earth next week
The two astronauts who launched on Starliner will stay behind on the International Space Station. Enlarge / Boeing's Starliner spacecraft undocks from the International Space Station at the conclusion of an unpiloted test flight.....»»
Doughnut-shaped region found inside Earth"s core deepens understanding of planet"s magnetic field
A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered by scientists from The Australian National University (ANU), providing new clues about the dynamics of our planet's magnetic field......»»
Africa"s "youthquake": Huge numbers of young people have no jobs, the wrong skills and little hope
By 2050, one in every three young people on Earth will be of African origin, according to the 2024 International Labor Organization's (ILO) Global Employment Trends for Youth report. Africa's young people will be key players in the direction of futur.....»»

Three studies conducted with the collaboration of the Helmholtz Institute Freiberg for Resource Technology, an institute of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), show significant progress in monitoring mining areas......»»
Study reveals crucial role of mixing Atlantic and Arctic waters in global ocean circulation
A new study sheds light on the vital role that the mixing of Atlantic and Arctic waters plays in sustaining the Atlantic Meridional Overturning Circulation (AMOC), which is crucial for regulating Earth's climate......»»
This tiny backyard bug does the fastest backflips on Earth
Move over, Sonic. There's a new spin-jumping champion in town—the globular springtail (Dicyrtomina minuta). This diminutive hexapod backflips into the air, spinning to over 60 times its body height in the blink of an eye, and a new study features t.....»»
Largest dam removal in US history nears completion, reviving hopes for California salmon
Excavators clawed at the remnants of Iron Gate Dam, clattering loudly as they unloaded tons of earth and rock into dump trucks......»»
Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
Land-sea "tag-team" devastated ocean life millions of years ago, reveal scientists
Scientists have revealed how a "tag-team" between the oceans and continents millions of years ago devastated marine life—and altered the course of evolution on Earth......»»
