Racism And Mental Health, How To Milk Ticks. March 26, 2021, Part 1

The Mental Health Costs Of ‘Everyday’ Racism

On March 16, a 21-year-old white man killed six Asian women and two other people in multiple shootings in Atlanta. Since the start of the COVID-19 pandemic, Asians and Asian-Americans in the U.S. have experienced a rise in racist attacks, which psychologists say are tied to anti-Chinese rhetoric from the former White House administration, as well as others who have scapegoated Asian Americans.

The Stop AAPI Hate reporting center was created in March of 2020 to track these events. The project is a collaboration between the Asian Pacific Planning and Policy Council, Chinese for Affirmative Action, and San Francisco State University’s Asian American Studies Department. The center reports that more than 3,700 acts of hate were brought to their attention between their founding and February 28 of this year, including verbal harassment or shunning, physical assault, and civil rights violations.

At the same time, people who identify as Asian-American and Pacific Islander (AAPI) have increasingly reported symptoms of anxiety or depression, or requested screenings for mental health diagnoses. Charissa Cheah, a professor of psychology at the University of Maryland-Baltimore County has found that even witnessing acts of hate or discrimination can affect someone’s mental health—and spill over to their children. And Kevin Nadal, a psychology researcher at John Jay College of Criminal Justice in New York, has documented how microaggressions, considered a more covert form of racism than physical violence, can cause trauma.

Cheah and Nadal discuss the connection between chronic exposure to racist behavior and mental health, along with resources for people who may be experiencing the effects of trauma, as well as the long history of anti-Asian racism in the United States.

To Milk A Tick

Ticks are masters of breaking down the defenses of their host organism to get a blood meal. They use anesthetics to numb the skin, anticoagulants to keep the blood flowing, and keep the host’s immune system from recognizing them as invaders and kicking them out. And the key to understanding this is in the tick’s saliva. Biochemist and microbiologist Seemay Chou discusses how she milks the saliva from ticks to study what compounds play key parts in these chemical tricks. She also talks about how ticks are able to control the microbes in their saliva.

A Year Of Staying Home Has Led To A Global Chip Crisis

The global pandemic has led to a different kind of worldwide crisis: a global chip shortage. Demand for semiconductor chips—the brains behind “smart” devices like TV’s, refrigerators, cars, dishwashers and gaming systems—has spiked after a year of staying and working from home. And the pressure on global supply chains has never been greater. Sarah Zhang, staff writer at The Atlantic, joins Science Friday to explain what happened.

Plus, why AstraZeneca came under fire from U.S. regulators this week and how one scientist has finally solved a 20-years-long mystery about the bald eagle.
