“Biden is trying to reclaim the vision of America that was there during the Obama administration, a vision that was much more diverse, much more religiously tolerant, much more tolerant of different kinds of gender dispositions and gender presentations,” said Norma Mendoza-Denton, a professor of anthropology at the University of California, Los Angeles, and an author of “Language in the Trump Era: Scandals and Emergencies.”
Sharon Dolovich, a professor at UCLA’s law school who directs its COVID-19 Behind Bars Data Project, which tracks the pandemic in prisons and jails nationwide, called the number of prisoners vaccinated in California “incredibly high.” “Generally speaking, prison systems have been slow to bring the vaccine to incarcerated people,” she said, explaining that

The next time you eat seafood, think about the long-term effects. Will consistently eating the biggest fish or the biggest conch mean that only the smaller individuals will have a chance to reproduce?
In Wonderland, Alice drank a potion to shrink herself. In nature, some animal species shrink to escape the attention of human hunters, a process that takes from decades to millennia. To begin to understand the genetics of shrinking, scientists successfully extracted DNA from marine shells collected at the Smithsonian Tropical Research Institute (STRI) in Panama. Their new technique will not only shed light on how animals from lizards to lemurs shrink, it will reveal many other stories hidden in shells.

In Wonderland, Alice drank a potion to shrink herself. In nature, some animal species shrink to escape the attention of human hunters, a process that takes from decades to millennia. To begin to understand the genetics of shrinking, scientists working at the Smithsonian Tropical Research Institute (STRI) in Panama successfully extracted DNA from marine shells. Their new technique will not only shed light on how animals from lizards to lemurs shrink, it will reveal many other stories hidden in shells. Humans are unique as predators, said Alexis Sullivan, doctoral student at Penn State University who did the field research as a short-term fellow at STRI. Most other animals go for smaller, younger, older or injured prey that are easy to catch, but humans often take the largest individual to feed many mouths or to display as a trophy.
