Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength. The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade – cooler than a typical campfire – without burning nuclear fuel. By contrast, the surface temperature of the Sun, a nuclear inferno, is about 5600 degrees. While not the coldest star ever found, it is the coolest so far analysed using radio astronomy. The findings are published today in The Astrophysical Journal. Lead author and PhD student in the School of Physics, Kovi Rose, said: “It’s very rare ...

SAN ANTONIO (July 13, 2023) — An artificial intelligence (AI) tool developed at The University of Texas Health Science Center at San Antonio accurately counts brain lesions on MRI scans within seconds. Once it is adapted to the clinic, the AI tool should help neuroradiologists to evaluate patients’ brain diseases at earlier stages. “Certain kinds of brain lesions are tremendously difficult to quantify without AI,” said researcher Mohamad Habes, PhD, of the health science center’s Glenn Biggs Institute for Alzheimer’s and Neurodegenerative ...
