AI beats real doctors on 149 remote OSCE-style tests

blog post image "We tested performance in consultations with simulated patients (played by trained actors), compared to those performed by 20 real PCPs using the randomized approach described above. AMIE and PCPs were assessed from the perspectives of both specialist attending physicians and our simulated patients in...

New protocluster of massive quiescent galaxies discovered

An international team of astronomers reports the discovery of a new protocluster of massive quiescent galaxies at a redshift of approximately 4.0. This is the first detection of a protocluster of this type at such a high redshift. The finding was detailed in a paper published Nov. 20 on the pre-print...

Particle physics could be rewritten after shock W boson measurement

“The standard model of particle physics has stood the test of time for decades, but now a new measurement of a particle called the W boson could indicate a chink in its armour.” The scientists took 10 years to do the analysis as it was so complex! “The analysis was so complex that the result took...

The Impact of Mask Distribution and Promotion on Mask Uptake and COVID-19 in Bangladesh

A growing body of scientific evidence suggests that face masks can protect against COVID-19. There is, however, limited rigorous evidence on the extent to which mask-wearing is effective in reducing COVID-19 in a real-life situation with imperfect and inconsistent mask use. In Bangladesh, researchers...

Tailored messaging increases understanding of climate change in Republicans

A team of researchers at Yale University's Yale Program on Climate Change Communication has found that the use of tailored advertising can increase awareness among Republicans of the dangers posed by climate change. In their paper published in the journal Nature Climate Change, the group describes field...

Human remains from Mary Rose show diversity of Tudor crew

A team of researchers with Cardiff University, the Mary Rose Trust, HM Naval Base and the British Geological Survey's National Environmental Isotope Facility has found evidence of racial diversity among the crew of the Mary Rose—a warship from the time of King Henry the VIII. In their paper published...

Using Markov chain model to evaluate medical students’ trajectory on progress tests and predict USMLE step 1 scores---a

Background Medical students must meet curricular expectations and pass national licensing examinations to become physicians. However, no previous studies explicitly modeled stages of medical students acquiring basic science knowledge. In this study, we employed an innovative statistical model to characterize...

Detection of a particle shower at the Glashow resonance with IceCube Nature.

The Glashow resonance describes the resonant formation of a W− boson during the interaction of a high-energy electron antineutrino with an electron1, peaking at an antineutrino energy of 6.3 petaelectronvolts (PeV) in the rest frame of the electron. Whereas this energy scale is out of reach for currently...

Heisenberg on Helgoland - the value of spending time in natural surroundings

"It was finally time to use his strange calculus to calculate the energy of a real physical system. As his excitement mounted he kept on making mistakes and correcting them, but finally he had it. When he looked at it he was struck with joy and astonishment. Out of the dance of calculations emerged an...

Can ultrasound novices develop image acquisition skills after reviewing online ultrasound modules? Elaine Situ-LaCasse.

Background Point-of-care ultrasound is becoming a ubiquitous diagnostic tool, and there has been increasing interest to teach novice practitioners. One of the challenges is the scarcity of qualified instructors, and with COVID-19, another challenge is the difficulty with social distancing between learners...

Simulations suggest Earth's oxygen-rich atmosphere will last only another billion years

A pair of researchers from Toho University and NASA Nexus for Exoplanet System Science has found evidence, via simulation, that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. In their paper published in the journal Nature Geoscience, Kazumi Ozaki and Christopher Reinhard...

Augmented reality could be the geology classroom

Augmented reality could be the geology classroom’s killer app "Geology is a very spatial science and can require a lot of 3-D visualization. Simple physical models (not to mention rocks) have long been used to aid teaching about things like faults or crystalline mineral structure. But these things...
