‘Would you like a little ice with your exoplanet?’ For Earth-like worlds, that may be a tall order

An artistic rendering showing an exoplanet with polar ice caps.

A team at the University of Washington and the University of Bern has computationally simulated more than 200,000 hypothetical Earth-like worlds all in orbit of stars like our sun. As they report in a paper accepted to the Planetary Science Journal and submitted Dec. 6 to the preprint site arXiv, on these simulated exoplanets, one common feature of present-day Earth was often lacking: partial ice coverage. About 90% of these potentially habitable hypothetical worlds lacked partial surface ice like polar caps.

‘Reservoir of disease’ within young population shows challenge for Washington’s reopening plans

An analysis of Washington state Department of Health data — published after peer review March 24 — has found that people under 40 years old have continued to become infected by the coronavirus at increasing rates even as the incidence of infection among older populations declines. The publication was available previously in preprint form on medRxiv. The study led by Judith Malmgren, affiliated epidemiologist in the UW School of Public Health, postulates that the increased spread of the virus among…

Purported phosphine on Venus more likely to be ordinary sulfur dioxide, new study shows

A University of Washington-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.

Colleges with primarily in-person instruction leading to thousands of COVID-19 cases per day in US

As universities and colleges struggle to find the right combination of in-person and online classes combined with protective measures to help prevent the spread of the novel coronavirus, a new study by researchers from four institutions has reached a troubling conclusion. Reopening university and college campuses with primarily in-person instruction is associated with a significant increase in cases of COVID-19 in the counties where the schools are located. “Consequently, we are able to predict between 1,000 and 5,000 additional cases…

Millions of US workers at risk of infections on the job, UW researchers calculate, emphasizing need to protect against COVID-19

A University of Washington researcher calculates that 14.4 million workers face exposure to infection once a week and 26.7 million at least once a month in the workplace, pointing to an important population needing protection as the novel coronavirus disease, COVID-19, continues to break out across the U.S. Marissa Baker, an assistant professor in the UW School of Public Health, based her calculations on research she published in 2018 in the American Journal of Industrial Medicine. In that paper, Baker…
