Gigantic asteroid impact shifted the axis of solar system"s biggest moon, study finds
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher has realized that the solar system's biggest moon's axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 t.....»»
Scientists develop multifunctional photocatalyst for wastewater treatment
Water contamination by pharmaceuticals and heavy metals poses severe environmental and health risks. Traditional methods like biodegradation and filtration often lack efficiency and sustainability. Photocatalysis, using solar energy to degrade pollut.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»

Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
By studying data from NASA's Parker Solar Probe and the ESA Solar Orbiter, an international team of astrophysicists has found that Alfvén waves drive the acceleration and heating of the solar wind......»»
U.S. delays final ruling to hike tariffs on EVs made in China
Higher duties of 100 percent on EVs, 50 percent on semiconductors and solar cells, and 25 percent on lithium ion batteries and key minerals, steel and aluminum, ship-to-shore cranes and syringes were set to take effect on Aug. 1......»»
NASA"s new solar sail extends its booms and sets sail
Solar sails are an exciting way to travel through the solar system because they get their propulsion from the sun. NASA has developed several solar sails, and their newest, the Advanced Composite Solar Sail System (or ACS3), launched a few months ago.....»»
Sunrise alarm clock didn’t make waking up easier—but made sleeping more peaceful

Exploring functional organic materials for the energy transition
Carbon, of all things, could help us to push forward the decarbonization of our industrial society. Functional carbon particles, known as carbon dots, can transform sunlight into energy and extract hydrogen from water. Prof. Dr. Dirk M. Guldi, a chem.....»»
South Africa"s coal workers face uncertainty—study shows they"re being left out of the green transition
South Africa is on the path to decarbonization—doing away with burning coal and other fossil fuels and moving towards renewable, clean energy, such as solar and wind power. However, the coal industry employs 91,000 people. If these workers lost the.....»»
Global timber supply threatened as climate change pushes cropland northwards
Climate change will move and reduce the land suitable for growing food and timber, putting the production of these two vital resources into direct competition, a new study has found......»»
NASA"s Europa Clipper gets set of super-size solar arrays
The largest spacecraft NASA has ever built for planetary exploration just got its "wings"—massive solar arrays to power it on the journey to Jupiter's icy moon Europa......»»
Breaking open the AI black box, team finds key chemistry for solar energy and beyond
Artificial intelligence is a powerful tool for researchers, but with a significant limitation: the inability to explain how it came to its decisions, a problem known as the "AI black box.".....»»
A way to recover silver from dead solar panels with 98% efficiency
A multi-institutional team of chemists, metallurgists and engineers has developed a highly efficient way to retrieve silver from dead solar panels. Their paper is published in Environmental Technology & Innovation......»»
