Quantum entangled photons react to Earth"s spin
A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work, published in Science Advances, represents a si.....»»
NASA is considering other ways of getting its Mars samples home
In 2021, NASA's Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected.....»»
Quebec lake meteorite impact yields rare rocks and evidence of extreme heat
For more than a decade, Western University planetary geologist Gordon "Oz" Osinski has led expeditions to Kamestastin Lake in Labrador. The environment is a perfect training ground because the properties and rock formations—created by the violent i.....»»
Astronomers discover an Earth-sized exoplanet orbiting a nearby ultracool dwarf star
An international team of astronomers reports the discovery of a new Earth-sized exoplanet that orbits an ultracool dwarf star located just 54.6 light years away. The newfound alien world, designated SPECULOOS-3 b, is slightly smaller but much hotter.....»»

Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
The important role of the Southern Ocean in global biological processes and the carbon cycle has been confirmed anew by a study published in Science that, for the first time based on field evidence, reveals the underappreciated role of inorganic zinc.....»»
Bye bye, El Nino. Cooler hurricane-helping La Nina to replace the phenomenon that adds heat to Earth
The strong El Niño weather condition that added a bit of extra heat to already record warm global temperatures is gone. It's cool flip side, La Niña, is likely to breeze in just in time for peak Atlantic hurricane season, federal meteorologists sai.....»»
Pair plasmas found in deep space can now be generated in the lab
An international team of scientists has developed a novel way to experimentally produce plasma 'fireballs' on Earth......»»
Ancient ocean slowdown warns of future climate chaos
When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A UC Riverside study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline......»»
How a single atomic sensor can help track Earth"s glaciers
Earth observations are one of the most essential functions of our current fleet of satellites. Typically, each satellite specializes in one kind of remote sensing—monitoring ocean levels, for example, or watching clouds develop and move. That is pr.....»»
Longer ice-free periods may lead to smaller Hudson Bay polar bear population, research suggests
Global warming is projected to lengthen the ice-free period in the Hudson Bay, reducing the length of the resident polar bears' hunting season, according to research published in Communications Earth & Environment. Under a temperature rise of more th.....»»
Researchers discover mysterious mini-Neptunes
Researchers discovered mini-Neptunes around four red dwarfs using observations from a global network of ground-based telescopes and the TESS space telescope. These four mini-Neptunes are close to their parent stars, and the three of them are likely t.....»»
Taylor Swift made "ground shaking" UK debut: Seismologists
Taylor Swift fans literally made the earth move as the US singer-songwriter began her UK tour, the British Geological Survey said on Thursday, with seismic activity recorded six kilometers (nearly four miles) away......»»
Research finds dolphins with elevated mercury levels in Florida and Georgia
In a study with potential implications for the oceans and human health, scientists have reported elevated mercury levels in dolphins in the U.S. Southeast, with the greatest levels found in dolphins in Florida's St. Joseph and Choctawhatchee Bays......»»
Study confirms the rotation of Earth"s inner core has slowed
University of Southern California scientists have proven that the Earth's inner core is backtracking—slowing down—in relation to the planet's surface, as shown in new research published in Nature......»»
Discovery of microfossil in China from the 518-million-year-old Qingjiang biota sheds light on adaptive evolution
Microbial sulfate reduction dating back to the Paleoarchean plays a crucial role in driving global carbon and sulfur cycles in ancient and modern Earth. Over 150 species of sulfate reducers from bacterial and archaeal phyla have been identified acros.....»»
