[ad_1] Wirz / UCLA Research Group The cold atmospheric plasma device that treats metal samples. The bluish glow is caused by the presence of excited air molecules. UCLA engineers and scientists have shown that cold atmospheric plasma treatments at room temperature can kill the coronavirus present on a variety of …

Notice how moth wings have weaker echoes (acoustic image) than butterfly wings.Marc Holderied and Thomas Neil False color 3D representation of a 0.21 mm …

[ad_1] Two teams of scientists have resolved a longstanding controversy over the origins of complex life on Earth. The joint studies found that molecular fossils extracted from 635-million-year-old rocks are not the earliest evidence of animals, but instead common algae. Researchers from the Australian National University (ANU), Max Planck Institute …

[ad_1] New research has found that water beneath glaciers in Antarctica and Greenland flows into nearby oceans, carrying elements that could affect how life grows and thrives. The study, published today in the Proceedings of the National Academy of Sciences, found that subglacial lakes in Antarctica and streams emerging from …

[ad_1] A Stanford research team that recently discovered an unexpected new chemical behavior of water when tiny droplets are formed from water vapor extended the results to natural, everyday water condensation. By Adam Hadhazy In its bulk liquid form, whether in a bathtub or an ocean, water is a relatively …

[ad_1] Within a single cell, thousands of molecules, such as proteins, ions and other signaling molecules, work together to carry out all types of functions: to absorb nutrients, storing memories and differentiate into specific tissues, among many others. Deciphering these molecules and all their interactions is a monumental task. Over …

[ad_1] Knowing exactly where proteins are frustrated could go a long way in making better drugs. This is one of the findings of a new study by Rice University scientists looking for mechanisms that stabilize or destabilize key sections of biomolecules. Atomic-scale models by rice theorist Peter Wolynes, lead author …

[ad_1] In the dusty desert town of Woomera in the South Australian desert, scientists are preparing. On December 6, 2020, after six years in space, the Japanese Aerospace Exploration Agency’s Hayabusa2 probe will finally return to Earth. It carries with it an incredibly rare, precious and hard-won cargo: at least …

[ad_1] The famed Arecibo radio telescope in Puerto Rico, which has provided invaluable service to scientists for more than five decades, 57 years to be exact, and has established itself in a well-known culture, is doomed to be dismantled after suffering irreparable damage in recent months. This gigantic telescope was …
