InspectIR breathalyzer COVID test, for article on COVID-19 breath test

First COVID-19 breath test authorized for use in U.S.

A COVID-19 breath test just cleared a major hurdle: the FDA has authorized the first device that can detect the virus from a single exhale, returning results in about three minutes. Made by InspectIR, the device picks up a signature pattern of five compounds the body releases during infection, and in a study of nearly 2,500 people it correctly flagged 91 percent of positive cases. No swabs, no lab. Beyond this moment, the authorization is a real proof of concept for breath-based diagnostics — a field researchers have long hoped could one day help detect cancers, kidney disease, and other conditions, especially in communities where traditional testing is hardest to reach.

Woman in graduation garb smiling, for article on student loan forgiveness

U.S. forgives 40,000 student loans, provides aid to 3.6 million more

Student loan relief reached a milestone in April 2022, when the U.S. Department of Education wiped out balances for roughly 40,000 public service workers — teachers, nurses, social workers, and public defenders whose forgiveness applications had long been tangled in technicalities. Another 3.6 million borrowers got at least three years of credit toward eventual cancellation, after the department fixed income-driven repayment rules that servicers had applied inconsistently for years. Behind the numbers are people who chose lower-paying careers partly because forgiveness made the math work, and finally saw that promise honored. It’s a reminder that even imperfect systems can be repaired when advocates, researchers, and policymakers push in the same direction — and that economic justice often arrives quietly, one fixed rule at a time.
