Need To Know
Lindsay Clancy Trial Begins
Jury selection began yesterday for Lindsay Clancy, a Massachusetts mother who killed her three children and is citing a rare defense: postpartum psychosis, a mental illness affecting one to two of every 1,000 mothers globally.
Some facts are not disputed: On Jan. 24, 2023, Clancy asked her husband to pick up takeout food and an item from the pharmacy. She then killed her three children before attempting to take her own life. Prosecutors characterize Clancy’s actions as premeditated and allege she consulted a mapping app to determine how long her husband would be away. Her defense team cites her efforts to seek psychiatric care—including admitting herself to a postpartum depression program—and argues she was overmedicated and hallucinating. Clancy’s husband sued her medical team this year, accusing them of failing to monitor her responses to the medications.
There is little precedent for the case. In 2006, Andrea Yates was found not guilty by reason of insanity after she killed her five children, citing psychotic delusions tied to postpartum depression.
The Cockroach Uprising
Tens of thousands of protesters marched toward India's Parliament in New Delhi yesterday before police fired tear gas to disperse the crowd. The self-described Cockroach Janta Party is demanding the education minister's resignation following repeated leaks of a medical entrance exam that millions of students see as determining their futures. See clashes unfold (w/photos).
The movement emerged in May after India's chief justice compared unemployed young people to "parasites" and "cockroaches" during a Supreme Court hearing. The party has since focused on India's medical entrance exam, where more than 2 million students compete annually for roughly 130,000 medical school spots. Families borrow money or even sell land to pay for years of private tutoring, while the competitive exam culture has also raised concerns about students' mental health.

Coffee Consumption Guidance
Most adults can safely drink up to five 8-ounce cups of black coffee per day, and regular consumption may improve cardiovascular health, the American Heart Association said yesterday.
An analysis of recent studies suggests consuming about 400 milligrams of caffeine daily may lower the risk of Type 2 diabetes, stroke, heart disease, and heart failure. However, because most research is observational, scientists are still unsure why caffeine may benefit heart health. Some studies suggest antioxidants in coffee help reduce inflammation, indicating not all caffeine sources offer the same effects. Synthetic caffeine products, such as energy drinks, have been linked to higher risk of high blood pressure and irregular heart rhythms. Coffee's benefits also diminish when sugar and high-fat creamers are added.
Brewing methods may matter, too. Cardiovascular benefits have been linked most strongly to paper-filtered or instant coffee. Unfiltered methods, including French press and espresso, retain cafestol, a natural compound that can raise artery-clogging cholesterol.
