A new study shows that the vast majority of patients who visited the Ruth and Harry Roman Emergency Department at Cedars-Sinai with suspected COVID-19 (novel coronavirus) symptoms, and who were treated and sent home to recuperate, recovered within a week.

The study, published by the Journal of the American College of Emergency Physicians Open, showed that none of those patients died from the virus and fewer than 1% required intensive care.
“When the pandemic began there was minimal evidence to guide us as to who should be hospitalized and who could be sent home,” said Sam Torbati, MD, co-chair and medical director of the Ruth and Harry Roman Emergency Department at Cedars-Sinai. “In real time, we began developing our criteria for who needed hospitalization for monitoring, intensive care, and who could recover at home. And this study shows our patients received the appropriate level of care.”

Fairy circles are one of nature’s greatest enigmas and most visually stunning phenomena. An international research team led by the University of Göttingen has now, for the first time, collected detailed data to show that Alan Turing’s model explains the striking vegetation patterns of the Australian fairy circles. In addition, the researchers showed that the grasses that make up these patterns act as “eco-engineers” to modify their own hostile and arid environment, thus keeping the ecosystem functioning. The results were published in the Journal of Ecology.

Researchers from Germany, Australia and Israel undertook an in-depth fieldwork study in the remote Outback of Western Australia. They used drone technology, spatial statistics, quadrat-based field mapping, and continuous data-recording from a field-weather station. With the drone and a multispectral camera, the researchers mapped the “vitality status” of the Triodia grasses (how strong and how well they grew) in five one-hectare plots and
