Earth is Trapping "Unprecedented" Amount of Heat, NASA Says
The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an "unprecedented" increase amid the climate crisis. From a report: Scientists from NASA, the US space agency, and the National Oceanic and Atm.....»»
We need to consider conservation efforts on Mars, say researchers
Astrobiology is the field of science that studies the origins, evolution, distribution, and future of life in the universe. In practice, this means sending robotic missions beyond Earth to analyze the atmospheres, surfaces, and chemistry of extraterr.....»»
Astronomers propose a new stellar theory to explain the origin of phosphorus
Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as "ONe novae" as a major source of phosphorus......»»
Transforming common soft magnets into next-generation thermoelectric conversion materials with 3-minute heat treatment
A research team from NIMS and Nagoya University has demonstrated that an iron-based amorphous alloy, widely used as a soft magnetic material in transformers and motors, can be transformed into a "transverse" thermoelectric conversion material that co.....»»
Researchers find unprecedented deep oxidative desulfurization with precisely designed Ti sites
In a study published in the journal National Science Review, a material synthesized by Dr. Shen Yu was used to introduce hydroperoxide into the synthesis system of titanium silicates......»»
First Dream Chaser spaceplane needs more work when it gets to launch site
The rest of Dream Chaser's heat shield tiles will be installed at Kennedy Space Center. Enlarge / Sierra Space's Dream Chaser spaceplane inside a NASA test chamber in Ohio. (credit: Sierra Space) There is still some work.....»»
NASA watchdog report: 100+ cracks on heat shield biggest threat to human moon mission
The damage to the Orion capsule from the Artemis I mission is already top of mind for NASA as it works to make the Artemis II mission safe for humans. But a new agency report has revealed the extent of the problem, including scores of cracks in Orion.....»»
Solid-state polymer heat pump gets rid of the heat itself
Polymer changes temperature, shape when charged, moving to where the heat needs to be. Enlarge (credit: Jorg Greuel) Heat pumps are the most energy-efficient way of controlling indoor temperature. By moving heat between.....»»
Researchers demonstrate enhanced radiative heat transfer for nanodevices
Researchers from Japan have been working hard to keep their cool—or at least—keep their nanodevices from overheating. By adding a tiny coating of silicon dioxide to micro-sized silicon structures, they were able to show a significant increase in.....»»
Researchers: Heat is coming for our crops—we have to make them ready
Australia's vital agriculture sector will be hit hard by steadily rising global temperatures. Our climate is already prone to droughts and floods. Climate change is expected to supercharge this, causing sudden flash droughts, changing rainfall patter.....»»
NASA confirms “independent review” of Orion heat shield issue
"There's no guarantee that changing the trajectory is the answer," says the Artemis II pilot. Enlarge / The Orion spacecraft after splashdown in the Pacific Ocean at the end of the Artemis I mission. (credit: NASA) NASA.....»»
Unearthing the impacts of hydrological sensitivity on global rainfall
Georgia Tech researcher Jie He set out to predict how rainfall will change as Earth's atmosphere continues to heat up. In the process, he made some unexpected discoveries that might explain how greenhouse gas emissions will impact tropical oceans, af.....»»
City Trees Save Lives
Green spaces significantly cool our ever-hotter cities. New research suggests more trees could cut heat-related ER visits in LA by up to two-thirds......»»
School"s out: how climate change threatens education
Record-breaking heat last month that prompted governments in Asia to close schools offers fresh evidence of how climate change is threatening the education of millions of children......»»
NASA reveals new target date for first crewed Starliner launch
Following Monday's postponement of the launch of the first crewed Starliner flight, NASA has revealed a new target date for the highly anticipated mission......»»
M4 iPad Pro CPU cores and RAM amount are tied to storage capacity
Apple has tied RAM to storage capacity in older iPads; it's a first for the CPU. Enlarge / The new M4 iPad Pro. (credit: Apple) When Apple announced the Apple M4 chip during its iPad Pro event yesterday, it mentioned tha.....»»
International SWOT mission can improve flood prediction
Rivers, lakes, and reservoirs are like our planet's arteries, carrying life-sustaining water in interconnected networks. When Earth's water cycle runs too fast, flooding can result, threatening lives and property. That risk is increasing as climate c.....»»
Webb presents best evidence to date for rocky exoplanet atmosphere
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system......»»
NASA and JAXA XRISM spot iron fingerprints in nearby active galaxy
After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151......»»
"Lost" spy satellite orbited Earth undetected for 25 years—until now, scientists say
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post.....»»
Study reveals new mechanism to explain how continents stabilized
Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism proposed by Penn State scientists may explain ho.....»»
