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 […]
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 […]
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 […]
Shockwaves through the “cosmic web” spotted Astronomers have detected the first evidence of shockwaves in intergalactic magnetic fields running throughout the cosmic web. Researchers combined data from four radio wave detection sites to identify the waves resulting from merging matter in the network of filaments that weave galaxies together. Full Story: Space First wiring map […]
Phytoplankton increasingly blooming on coastlines Phytoplankton blooms increased around 13% in extent and occurred 59% more often along global coastlines between 2003 and 2020. The microscopic algae are both beneficial to fisheries and potentially dangerous for marine animals in large amounts, researchers note, and the increase in phytoplankton blooms is caused by warmer ocean temperatures […]
Ancient fish that ate humans’ ancestors discovered Researchers have excavated the remains of a giant ancient bony fish species with fangs from about 350 million years ago in what is now South Africa. The findings, published in the journal PLOS One, indicate that the Hyneria udlezinye species measured up to 2.7 meters long and likely […]
Analysis of cell villages yields insight into Zika infections Studying cell villages, or samples from different donors in a shared environment, is an effective method “to identify genes and genetic variants that change a cell’s phenotype.” Scientists used the method along with the Dropulation and Census-seq algorithms to assess genetic variation in cell villages and […]
Astronomers puzzled by distant planet’s ring Astronomers have discovered a ring around the distant minor planet Quaoar that defies scientific understanding of how and where rings are formed. Quaoar’s ring exists in a location outside of where scientists believe particles should remain in a disk formation, prompting questions about the nature of celestial rings. Full […]
Human brain tissue successfully implanted in rats A new study shows that balls of human brain neurons can be implanted and integrated into the brains of rats. Researchers reveal that lab-grown “human brain organoids” integrated into the rats’ brains within three months, which may pave the way for repairing injured human brains in the future […]
