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.....»»
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.....»»

Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Unveiling the hottest period in a million years: The MIS 11c paradox
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a ke.....»»
