Career and technical education teachers in an Idaho district are shifting what are traditionally hands-on lessons to a virtual format amid what are expected to be prolonged school closures. In some cases, teachers are planning to film themselves welding, and students can record projects they finish at home.
The brains of early hominid species Australopithecus afarensis were small, like those of chimps, and they grew at a slow pace, as human brains do, according to a study published in Science Advances. The slow post-birth brain growth may have helped mothers by easing some physical and nutritional aspects of caring for children, and "likely provided a foundation for the evolution of long childhoods in the human lineage," said study author Philipp Gunz.
Evidence that a rainforest once flourished near Antarctica has been found and described in Nature. Researchers found spores and roots dating back to the Cretaceous period when they drilled into the floor of the Amundsen Sea.
Many other research projects have come to a stop due to stay-at-home rules and lab closures, but coronavirus research has skyrocketed worldwide, with open collaboration and data sharing occurring with unprecedented speed. "The ability to work collaboratively, setting aside your personal academic progress, is occurring right now because it's a matter of survival," says Harvard Medical School assistant professor Ryan Carroll.
A high-school student in Connecticut, motivated by news of equipment shortages among health care workers, is using 3D printers to manufacture protective shields. He also connected with an engineer, who he is collaborating with to make frames for the shields.
Hawaii's public high schools offer work-based lessons designed to prepare students for future careers. One high school features an academy program that allows students' career pathways to be integrated across the curriculum.
Some scientists are weighing what the lasting environmental effects of the coronavirus pandemic will be once measures that have led to decreased emissions globally are lifted. The effects could in some ways be similar to the environmental impact of the financial crisis of 2008, said Julia Pongratz, professor for physical geography and land use systems at the University of Munich.
The coronavirus outbreak won't necessarily disrupt Africa's food supplies, but it could make it more difficult for people to actually get food, writes William Moseley of Macalester College. The pandemic could restrict employment opportunities, and efforts to close markets for public health reasons could limit access, he notes.
The coronavirus outbreak has led to delayed or canceled field research for scientists, leaving many to consider how data collection and ongoing studies will be affected. This article highlights their concerns and describes how some are taking this time to consider how they can change or improve their research methods.
