Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere. How OH itself forms in the atmosphere was viewed as a complete story, but in new research published in Proceedings of the National Academy of Sciences, a research team that includes Sergey Nizkorodov, a University of C

Ice sheets can retreat up to 600 metres a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers, led by Dr Christine Batchelor of Newcastle University, UK, used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the

A new insightful study reveals that the mass loss of lake-terminating glaciers in the greater Himalaya has been significantly underestimated, due to the inability of satellites to see glacier changes occurring underwater, leading to critical implications for the region's future projection of glacier disappearance and water resources. The research, which combines multi-temporal satellite data wit

Sixty per cent of the world's fresh water is bound up in Antarctic ice sheets. Thirty million cubic kilometres of ice is perhaps a difficult number to grasp. But if absolutely all Antarctica's ice melted, the seas would rise by 58 metres on average. "The ice sheet in East Antarctica stores enormous amounts of water. This means that this is the biggest possible source of future sea level ri

The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature - one can only approach absolute zero. This is the third law of thermodynamics. A research team at TU Wien (Vienna) has now investigated the question: How can this law be reconciled with the rules of quantum physics? They succeeded in developing a "quantu

Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a paper in Science Advances, could lead to more efficient and robust wireless communications and significantly improved lasers. Time crystals were first conceived by Nobel laureate Frank Wilczek in 2012. Mun

Using two decades of NASA satellite measurements stored in the cloud, scientists recently assessed the vulnerability of Belize's renowned coral reefs to bleaching and collapse. The findings could help management authorities protect the reefs from human impacts such as development, overfishing, pollution, and climate change. The 185-mile-long (298-kilometer-long) barrier reef system off the

SatixFy Communications Ltd. (NYSE AMERICAN: SATX) has completed a contracted demonstration with OneWeb Technologies ("OWT"), and the Air Force Research Lab ("AFRL"), to demonstrate SatixFy's new antenna for use by the United States Department of Defense (DoD), under its initiative Defense Experimentation Using Commercial Space Internet (DEUCSI). This program was executed in partnership with the

Pituffik Space Base, Greenland (AFNS) Apr 07, 2023
Thule Air Base, the Department of Defense's northernmost installation, has been renamed to recognize Greenlandic cultural heritage and better reflect its role in the U.S. Space Force. Following a ceremony held April 6, the installation is now known as Pituffik Space Base. Pituffik (pronounced bee-doo-FEEK) is the traditional Greenlandic name of the region where the base is located. The ren

At least five ice ages have befallen Earth, including one 635 million years ago that created glaciers from pole to pole. Called the Marinoan Ice Age, it's named for the part of Australia where geologic evidence was first collected in the 1970s. Scientists say the Marinoan Ice Age was one of the most extreme in the planet's history, creating glacial ice that persisted for 15 million y
