HIP 99770 b is the first exoplanet detected through a pioneering approach that combines direct imaging with astrometry, the precise measurements of a star’s motion in the sky. This innovative method holds great promise for enhancing the efficiency of exoplanet searches, bringing us closer to the long-awaited discovery of an Earth-like twin in the vast […]
Scientists use AI to sharpen first black hole image Scientists have used artificial intelligence to refine the first image of a black hole taken in 2019. The picture reveals a skinnier doughnut-shaped ring and darker center than the original image. Full Story: The Associated Press Volcanic eruptions led to 2 ancient extinctions Carnivores died in […]
Scientists ran a comprehensive analysis of data from collisions of heavy ions (actually, nuclei of atoms) to determine which factors most influence fluctuations in the flow of particles . They found that the conditions that are established just as the ions collide have the greatest impact. These conditions are related to the size of the […]
Tiger personality may be correlated with health Surveys of caretakers for 248 Siberian tigers at two fenced wildlife sanctuaries in China suggest that tigers have distinct personalities. Nearly 40% of the tigers’ behaviours fell into the “majesty” category, described as confident, competitive, and ambitious, or the “steadiness” category, reflecting obedience, tolerance, and gentleness. Those demonstrating […]
Quantum hair: The solution to the Hawking paradox? Researchers claim to have solved the Hawking paradox, or the conflict between quantum mechanics and the idea that black holes destroy all information about the stars that served as their creators. They suggest the radiation around black holes, also known as quantum hair, can hold onto information […]
Nuclear physicists have found a new way to see details inside atomic nuclei . They do so by tracking interactions between photons and gluons—the gluelike particles that hold together the building blocks of protons and neutrons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled […]
Fish can feel each other’s fear Fish can detect emotions like fear in other fish and change their behaviour accordingly. The scientists manipulated genes associated with oxytocin, the neural chemical linked to empathy in humans, in zebrafish and found that those without the genes failed to respond to the feelings of other fish that were […]
A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials — like a tailor altering a suit — could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases […]
Rising seas, oxygen depletion led to mass extinction Rising seas likely contributed to high hydrogen sulfide levels and oxygen depletion that killed marine life during Earth’s Devonian period over 350 million years ago. Researchers analyzed black shale samples from the Bakken Formation underlying parts of North Dakota and Canada, finding that waters were drained of […]
Pyrite, also known as “fool’s gold,” is an abundant iron sulphide mineral in the Earth’s crust. All organisms need iron and sulphur to grow. Because pyrite does not dissolve in oxygen-free conditions, scientists previously thought that organisms could not use pyrite in the absence of oxygen. Research shows that certain single-celled microorganisms can dissolve pyrite […]
