Stars have life cycles. They're born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die....
The increased freshwater from melting Antarctic ice sheets plus increased wind has reduced the amount of oxygen in the Southern Ocean and made it more acidic and warmer, according to new research led by University of Arizona geoscientists.
The researchers...
A new submarine volcano was formed off the island of Mayotte in the Indian Ocean in 2018. This was shown by an oceanographic campaign in May 2019. Now, an international team led by the scientist Simone Cesca from the...
Life as we know it requires phosphorus. It's one of the six main chemical elements of life, it forms the backbone of DNA and RNA molecules, acts as the main currency for energy in all cells and anchors the...
Winter weather patterns in North America are dictated by changes to the polar vortex winds high in the atmosphere, but the most significant cold snaps are more likely influenced by the tropics, scientists have found.
A team led by the...
New research suggests forces pulling on Earth's surface as the planet spins may trigger earthquakes and eruptions at volcanoes.
Seismic activity and bursts of magma near Italy's Mount Etna increased when Earth's rotational axis was furthest from its geographic axis,...
Research published this week by University of Wisconsin-Madison scientists shows how bacteria can degrade solid bedrock, jump-starting a long process of alteration that creates the mineral portion of soil.
Soil, which the aphorism describes as "that thin layer on the planet that...
New evidence gleaned from Antarctic seashells confirms that Earth was already unstable before the asteroid impact that wiped out the dinosaurs.
The study, led by researchers at Northwestern University, is the first to measure the calcium isotope composition of fossilized...
Scientists have identified systematic meanders in the globe-circling northern jet stream that have caused simultaneous crop-damaging heat waves in widely separated breadbasket regions-a previously unquantified threat to global food production that, they say, could worsen with global warming. The...
Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws—and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban downtown to a remote glacier.
In Seismological...
How did life survive the most severe ice age? A McGill University-led research team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans were cut off from...
