Large deposits of plagioclase feldspar found in the walls of Valles Marineris on Mars
A team of researchers at Université de Lorraine in France, working with a colleague from Brock University in Canada, and one each from Université Clermont Auvergne and Université Lyon, both in France, has found evidence of large deposits of plagio.....»»
Atmospheric oxidation and the creation of modern Mars
Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period known as the Late Heavy Bombardment. But whereas today.....»»
Strangler figs prefer large host trees, study finds
The strangler fig, as a hemi-epiphyte, is renowned for its unique "strangling" behavior. Its colonization and establishment on some trees in tropical urban green spaces form a distinctive ecological landscape, enriching the ecological functions of ci.....»»
Can walls of oysters protect shores against hurricanes? Darpa wants to know.
Colonized artificial reef structures could absorb the power of storms. On October 10, 2018, Tyndall Air Force Base on the Gulf of Mexico—a pillar of American air superiority—f.....»»
Novel algorithms detect precursory scale increase to help forecast big quakes
Many people are aware that large earthquakes are often followed by a sequence of aftershocks as stresses are redistributed in the surrounding area. Many may not be aware that there are also sequences of earthquakes that occur before most large earthq.....»»
Mars analog stations investigate lichen biodiversity during simulated missions
Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. The.....»»
This 40% off 75-Inch Hisense 4K TV will steal the show at your next family gathering
Hisense When it comes to getting a new TV, there’s a mantra that many of us like to follow: bigger is better. 75-inch and over TVs usually have a price tag to match their large size, but thanks to Best Buy’s , that doesn’t have to b.....»»
Darpa Thinks Walls of Oysters Could Protect Shores Against Hurricanes
The US defense research agency is funding three universities to engineer reef structures that will be colonized by corals and bivalves and absorb the power of future storms......»»
Machine learning could improve extreme weather warnings
Because small changes in atmospheric and surface conditions can have large, difficult-to-predict effects on future weather, traditional weather forecasts are released only about 10 days in advance. A longer lead time could help communities better pre.....»»

How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues
Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds or perhaps even thousands of kilometers......»»
Catastrophically warm predictions are more plausible than previously thought, say climate scientists
What will the future climate be like? Scientists around the world are studying climate change, putting together models of the Earth's system and large observational datasets in the hopes of understanding—and predicting over the next 100 years—the.....»»
How the "social cost of carbon" measurement can hide economic inequalities and mask climate suffering
The social cost of carbon (SCC) is an essential tool for climate decision-making around the world. SCC is essentially a large cost-benefit calculation that helps policymakers compare the benefits of reducing carbon dioxide (CO2) emissions to the soci.....»»
Mazda hits hybrid high gear as CEO Masahiro Moro teases new electrified technologies
CEO Masahiro Moro says Mazda is developing a new full-hybrid drivetrain in-house as the company launches hybrid versions of its CX-80 crossover, the fourth product riding on the Japanese carmaker's large-vehicle platform......»»
Hurricane Milton Shows How a Storm’s Category Doesn’t Tell the Full Story
Milton’s reclassification to a Category 3 storm suggests it is weakening, but the scale accounts only for wind speed and not hurricane size, storm surge heights, or rainfall—which are all catastrophically large......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Team discovers three new magnetic and helium-enriched hot subdwarf stars
An international team of astronomers reports the discovery of three new helium-enriched hot subdwarf stars with strong magnetic fields. The finding, made with the Southern African Large Telescope (SALT), is detailed in a research paper published Oct......»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
Reports: China hacked Verizon and AT&T, may have accessed US wiretap systems
Chinese hackers were in networks of major ISPs “for months,” WSJ reports. Chinese government hackers penetrated the networks of several large US-based Internet service provide.....»»
Nuclear rockets could travel to Mars in half the time, but designing the reactors that would power them isn"t easy
NASA plans to send crewed missions to Mars over the next decade—but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip......»»
