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.....»»
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.....»»
Roku owners face the grimmest indignity yet: Stuck-on motion smoothing
Software updates strike again, leaving interpolated frames in unwanted places. Enlarge / Motion smoothing was making images uncanny and weird long before AI got here. (credit: Aurich Lawson | Getty Images | Roku) Roku TV.....»»
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.....»»
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......»»
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.....»»
A mission to find 10 million near-Earth asteroids every year
So far, scientists have found around 34,000 near-Earth asteroids (NEAs) that could serve as humanity's stepping stone to the stars. These balls of rock and ice hold valuable resources as we expand throughout the solar system, making them valuable rea.....»»
Parabolic flight with exoskeleton: Researchers test fine motor skills in weightlessness
Fine motor tasks under space conditions are particularly challenging and must first be trained on Earth. Scientists from the German Research Center for Artificial Intelligence (DFKI) and the University of Duisburg-Essen (UDE) are investigating whethe.....»»
While aiming for massive gas cloud, astronomers spot differences in thickness of Milky Way Galaxy
Space may appear vast and empty, but it's full of cosmological objects that are invisible to the human eye. From our vantage point on Earth, many of these objects fall between astronomers and what they hope to observe, impacting what they find. This.....»»
UAW members authorize strike at BMW regional distribution center
The UAW voted 99 percent in favor of authorizing a strike at the Nazareth, Pa., regional distribution center. Negotiations are ongoing, and the contract is set to expire June 30......»»
Satellite "megaconstellations" may jeopardize recovery of ozone hole
When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer. A new study finds that these oxides have increased 8-fold between 2016 and 2022 and wi.....»»
Study shows magnesium oxide undergoes dynamic transition when it comes to super-Earth exoplanets
Researchers from Lawrence Livermore National Laboratory (LLNL) and Johns Hopkins University have unlocked new secrets about the interiors of super-Earth exoplanets, potentially revolutionizing our understanding of these distant worlds......»»
Aerosols may affect climate more than previously thought
A key to improving climate prediction is to improve understanding of the impact of aerosol on clouds, commonly known as the aerosol-cloud-interaction, according to a new study led by Earth System Science Interdisciplinary Center (ESSIC) researchers p.....»»
