Zoom fatigue may be a real condition, but for some people, the “constant mirror” effect of seeing their own faces didn’t appear to make virtual meetings more unpleasant, a Washington State University study has found. The study surveyed two groups who attended regular virtual meetings as a result of the pandemic: employees and college students. The participants’ attitudes toward the self-view feature depended on an individual trait—public self-consciousness. Those low in this trait tended to have more positive attitudes toward their virtual meetings the more often their own faces were visible to them.

Research led by UC Davis Professor Garen Wintemute shows that violence indirectly impacts most Californians. Though relatively few may experience or witness a violent act, a large majority of surveyed Californians reported having an “experience of violence” (EV). These included hearing gunshots in their neighborhood, encountering a sidewalk memorial to a violent death or learning about a violent event through their social network.

Genetic information is now indispensable for modern plant breeding. Genome sequencing is now much cheaper than it was, but still accounts for a large part of the costs in animal and plant breeding. One trick to reduce these costs is to sequence only a very small and randomly selected part of the genome and to complete the remaining gaps using mathematical and statistical techniques. Researchers at Göttingen University have developed a new approach to do this, as published in PLOS Genetics.

In a paper published in National Science Review, an international team of scientists evaluate scenarios about what is causing methane concentrations to rapidly increase in the atmosphere. By combining new and novel isotopic datasets on methane source ‘signatures’ with simple atmospheric models, they ran thousands of potential emission pathways and isolated those that best matched the observed change of methane isotopes in the atmosphere. Using this approach, the authors found that the methane sources most likely driving the increase are from human activities, including agriculture, landfills and waste management, and from the use of coal, oil and gas. These activities are responsible for more than 80% of the rise of atmospheric methane since 2007. The analysis suggests that wetland emissions have not contributed significantly to increases in atmospheric methane, despite continued warming and climate extremes.
