Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises -- especially when NASA's Hubble Space Telescope takes a close-up look at it. Hubble's new observations of the famous red storm, collected 90 days between December 2023 to

Toxic trace elements such as lead, mercury, arsenic, and cadmium naturally occur in small quantities in coastal seas. However, human activities, such as industry and agriculture, contribute significantly larger amounts. A new study has examined how climate change already affects the distribution and accumulation of these elements and how it could impact them in the

161,979 new RNA viruses have been discovered using a machine learning tool that researchers believe will vastly improve the mapping of life on Earth and could aid in the identification of many millions more viruses yet to be characterized. Artificial intelligence (AI) has been used to reveal details of a diverse and fundamental branch of

Researchers have created a high-performance polymer that can be chemically recycled without compromising its heat and chemical resistance. The revolutionary design includes a directing group that allows links in the polymer to be broken easily with a catalyst and the original polymer to be reformed in few steps. The directing group could be included in

An estimated one in five Americans live with chronic pain and current treatment options leave much to be desired. Scientists are now using artificial intelligence (AI) for drug discovery in advanced pain management. The team's deep-learning framework identified multiple gut microbiome-derived metabolites and FDA-approved drugs that can be repurposed to select non-addictive, non-opioid options to

Using peptides and a snippet of the large molecules in plastics, materials scientists have developed materials made of tiny, flexible nano-sized ribbons that can be charged just like a battery to store energy or record digital information. Step aside hard, rigid materials. There is a new soft, sustainable electroactive material in town -- and it's

Researchers recently developed electronic tongue capable of identifying differences in similar liquids, such as milk with varying water content; diverse products, including soda types and coffee blends; signs of spoilage in fruit juices; and instances of food safety concerns. They found that results were even more accurate when artificial intelligence used its own assessment parameters

Researchers show that for the first time they have achieved atomic-scale observations of grain rotation in polycrystalline materials. Using state-of-the-art microscopy tools, the scientists were able to heat samples of platinum nanocrystalline thin films and observe the mechanism driving grain rotation in unprecedented detail. Researchers at the University of California, Irvine and other international institutions

Engineers built a solar-powered desalination system that produces large quantities of clean water despite variations in sunlight throughout the day. Because it requires no extra batteries, it offers a much more affordable way to produce drinking water, compared to other solar-driven designs. MIT engineers have built a new desalination system that runs with the rhythms

Unearthing new LEDs, solar cells, and photodetectors requires extensive knowledge surrounding the optical properties of materials. Calculating these takes time and resources. Yet researchers unveiled a new AI tool that can accurately, and crucially much faster than quantum simulations, for predicting optical properties. Researchers from Tohoku University and the Massachusetts Institute of Technology (MIT) have

Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black hole) exhibits a precessional motion driven by the black hole's spin. This finding underscores the potential of this spin to be the primary driver of the periodic fluctuations in luminosity

NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life -- with evidence for widespread liquid water on the surface -- to a surface that is inhospitable to terrestrial life as we know it.
