AI Not Ready to Replace Radiologists Interpreting Chest X-Rays
Commercially available artificial intelligence (AI) tools were accurate to varying degrees in flagging chest x-ray abnormalities but turned up more false-positives than radiology reports, a Danish study found. Testing four CE-marked AI tools on real-world radiographs from the Copenhagen region, investigators reported areas under the receiver operating characteristic curves ranging from 0.83-0.88 for airspace disease, […]
Paris Climate Agreement goal still within reach, suggests new study
The Paris Climate Agreement goal to limit global warming this century to 3.6 degrees Fahrenheit (2 degrees Celsius) over pre-industrial temperatures is still within reach, while apocalyptic, worst-case scenarios are no longer plausible, suggests a new CU Boulder analysis. Out today in Environmental Research Letters, the new study finds that a subset of climate scenarios […]
Bringing the sun into the lab: Liquid-metal experiment provides insight into the heating mechanism of the sun’s corona
Why the Sun’s corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A “hot” trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using […]
