ENERGY TRANSITIONS: Building wind, solar can be cheaper than existing gas
Wind and solar are now the cheapest forms of power generation in many parts of the world, according to the investment bank Lazard Ltd. In some cases, building renewables is even cheaper than running existing coal and gas plants.
Aquarius? Hereâs your constellation
Aquarius lies in a âwateryâ part of the sky, near Pisces the Fish, Cetus the Whale, Eridanus the River, and Piscis Austrinus the Southern Fish.
Colorful perovskites: Thermochromic window technologies
Scientists report a breakthrough in developing a next-generation thermochromic window that not only reduces the need for air conditioning but simultaneously generates electricity.
Radiative cooler that cools down even under sunlight
Now that autumn is upon us, there is a large temperature gap between day and night. This is due to the temperature inversion caused by radiative cooling on the Earth’s surface. Heat from the sun during the day causes its temperature to rise and when the sun sets during the night, its temperature cools down. Recently, a research team has demonstrated a daytime radiative cooling effect which exhibits lower temperatures than its surroundings even during the day.
75 ways Trump made America dirtier and the planet warmer
“I want crystal clean water and air.” That’s what Donald Trump said in the first chaotic presidential debate with Joe Biden. But there is scant evidence of that desire in the actions of his administration, which has spent nearly four…

Severe air pollution drives food delivery consumption and plastic waste
When the air outside is bad, office workers are more likely to order food delivery than go out for lunch, which in turn increases plastic waste from food packaging, according to a study by researchers from the National University of Singapore.
Prebiotic chemistry: In the beginning, there was sugar
Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? Chemists now reports a reaction pathway in which minerals catalyze the formation of sugars in the absence of water.
High social and ecological standards for chocolate
Worldwide demand for food from the tropics that meets higher environmental and social standards has risen sharply in recent years. Consumers often have to make ethically questionable decisions: products may be available through child labor, starvation wages or environmental destruction. Building on an interdisciplinary project in Peru, an international research team published an overview on the transition to responsible, high-quality cocoa production.
Glimpse deep into Earth’s crust finds heat source that may stabilize continents
(Penn State) Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth’s crust, revealing new evidence for how continents remain stable over billions of years, according to a team of scientists.
