A brutal protest in Charlottesville, Virginia, left three people dead and dozens injured on Aug. 11 and 12 as white nationalists, white supremacists and Neo-Nazis descended on the city and clashed violently with anti-racism protestors. President Donald Trump initially condemned the conflict on Twitter and then a few days later placed blame upon both parties involved in the clash. The event, which has rattled Americans, has brought racial tensions to the forefront. In this episode, Professors Julian Zelizer and Sam Wang discuss the aftermath of Charlottesville — and what to expect in the weeks ahead.

Children who grow up in urban counties with high upward mobility exhibit fewer behavioral problems and perform better on cognitive tests, according to a study led by Princeton University. Children in these counties display fewer behavior problems at age 3 and show substantial gains in cognitive test scores between ages 3 and 9. Growing up in a county with higher intergenerational mobility reduces the gap between economically advantaged and disadvantaged children’s cognitive and behavioral outcomes by around 20 percent.

Princeton University researchers have uncovered a critical role for a new immune signaling pathway in controlling infection by the flavivirus Yellow Fever Virus (YFV). Infection with YFV causes a devastating illness with a mortality rate of up to 50%. Like other members of its viral family—which includes West Nile Virus, Dengue Virus and Zika Virus—YFV is transmitted to humans by mosquitos that are expanding into new areas across the globe, exposing more people to these dangerous viruses. Fortunately, there is an effective vaccine for YFV: a live-attenuated strain of the virus, called YFV-17D, which differs by only a few amino acids from the virulent viral strain YFV-Asibi, but nonetheless provokes a potent and durable protective immune response in humans.

Three days of panel discussions, presentations and conversations at Princeton University’s recent ethnography and entrepreneurship conference produced a rich stew of questions with no great consensus — just the way Derek Lidow wanted it. Consensus often leads to mediocrity, said Lidow, an entrepreneur who teaches at Princeton’s Keller Center for Innovation in Engineering Education. The conference, “Expanding Understanding of Business Creation: Adding More Ethnography into the Research Mix,” offered insights on ways that ethnography — the study of specific cultures — can help startup teams develop new businesses.

Physicians trained at the United States’ lowest-ranked medical schools write more opioid prescriptions than physicians trained at the highest-ranked schools, according to a study by Princeton University researchers. The study suggests that better training for physicians, and for general practitioners in particular, could help curb the nation’s opioid epidemic.

Are two languages at a time too much for the mind? Caregivers and teachers should know that infants growing up bilingual have the learning capacities to make sense of the complexities of two languages just by listening. In a new study, an international team of researchers, including those from Princeton University, report that bilingual infants as young as 20 months of age efficiently and accurately process two languages.

Researchers have had trouble explaining why black children are much more likely than other children to suffer from asthma. A new study by Princeton University strongly suggests that much of the answer lies in persistent residential segregation, which traps minority children in unhealthy, polluted neighborhoods.

If climate change is not curbed, increased precipitation could substantially overload waterways in the United States with excess nitrogen, according to a new study published July 28 in the journal Science. A team of researchers, including those from Princeton University, reported that climate change-induced precipitation changes will increase nitrogen pollution, especially in the Midwest and Northeast. This will, in turn, worsen eutrophication, a process by which waterways become overloaded with nutrients.

The hardest thing about concrete just might be the problem of how to make the ubiquitous building material in an environmentally friendly manner. Recent laboratory results at Princeton University indicate that the challenge of making greener concrete may eventually be cracked. Concrete raises climate-change concerns because manufacturing its primary component, Portland cement, is responsible for as much as 8 percent of human carbon dioxide emissions. Even worse from an environmental standpoint, forecasters predict Portland cement production will double over the next 30 years.

Dogs’ ability to communicate and interact with humans is one the most astonishing differences between them and their wild cousins, wolves. A new study published today in the journal Science Advances identifies genetic changes that are linked to dogs’ human-directed social behaviors and suggests there is a common underlying genetic basis for hyper-social behavior in both dogs and humans.
