Researchers found that black and turkey vultures ingest more plastic in landscapes with more developed landcover and higher densities of commercial food providers. They may eat plastic thinking it's nutritious bone fragments or intentionally to collect bulk for vomiting up indigestible parts of carrion.
Research from the University of Kansas shows that families in Washington D.C.'s school choice policy are making choices that perpetuate segregation. Despite having more opportunities for integration, white families are returning to city centers and using tactics such as gaming the lottery system to secure spots in desirable schools.
A new model shows that encampment sweeps, bans and move-along-orders contribute to 15-25% increase in deaths among people experiencing homelessness over a 10-year period. Involuntary displacement is linked to increased overdose deaths, hospitalizations, injection-related infections and hindered access to medications.
