Tear gas has been controlling crowds for a century. How does it work? Can it cause permanent harm?
PHILADELPHIA — Christopher Rapuano, chief of the cornea service at Wills Eye Hospital, got a small dose of tear gas a few years ago as he stood on the fringes of a demonstration in Hong Kong. His eyes started to burn. Then they teared up and his vision blurred. He ran to fresher air.Chris Cramer, a University of Minnesota chemist, got much bigger doses while in the Army, where he was a chemical weapons specialist. To underscore the value of gas masks, soldiers in training would don the masks, wait until tear gas had been fired, then take them off.“It feels as though bees are stinging you in yo...

Will orcas thrive in the coronavirus pandemic's quieter waters? Scientists aim to find out
SEATTLE — The coronavirus pandemic has upended and refocused orca field research in Northwest waters this season.Some scientists are beached. Others are investigating the effect on endangered southern resident orcas of suddenly much quieter home waters in the Salish Sea, the transboundary waters between the United States and Canada including Puget Sound.The southern residents hunt by sound. Disturbance and noise caused by boats and vessels is one of three main threats to their survival, in addition to lack of adequate chinook salmon (their preferred food) and pollution. So this spring like non...

Living with Children: The power of 'no'
In 1972, a Stanford University psychologist conducted a study in which young children, individually, were offered either a small but immediate reward (a marshmallow or a pretzel) or a doubled reward if they were able to wait for 15 minutes. In follow-up studies, researchers found that children who were able to postpone gratification experienced better life outcomes as measured by such things as SAT scores, academic achievement and body mass index.I have long maintained that well-done research in the so-called social sciences does nothing but confirm common sense, and it certainly seems common-...

Captain Comics: Welcome back, Justice Society
“Stargirl” has arrived on DC Universe and The CW, bringing with it the return of the justly legendary Justice Society of America.The Justice Society is the oldest superhero team in comics, arriving in “All-Star Comics” #3 in 1940. Another milestone: The team combined characters from two different publishers, “sister” companies Detective Comics Inc. and All-American Comics Inc. (Eventually these companies would merge into today’s DC Comics.)The publishing premise of the JSA was simple: The team starred second-tier characters who did not have their own self-named titles, in the hopes that the ad...

Why is the coronavirus infection usually mild in children? Here's a new clue
One of the biggest mysteries of the new coronavirus is its relative harmlessness in most children who get infected.At least part of the explanation may be in the cells lining their noses, according to a new study by researchers at the Icahn School of Medicine at Mount Sinai in New York City.The researchers started with archived samples of cells from the nasal lining, or epithelium, of people ages 4 to 60. Then they measured the activity of a gene that directs production of ACE2, a protein that helps coronavirus enter the body. It turned out that ACE2 gene “expression” — the DNA instructions th...

Commentary: UN must extend arms embargo on Iran — and US should have a backup plan
Diplomats at the United Nations have less than six months to stop Iran — the world’s leading state sponsor of terrorism, violator of nuclear nonproliferation agreements and catalyst for regional warfare — from buying weapons from the world’s most eager salesmen, Vladimir Putin and Xi Jinping.The U.N. arms embargo on Iran is scheduled to sunset starting in October, and if it does, Tehran and its terror proxies, regional allies and the Islamic Revolutionary Guard Corps will be stronger than ever. Our first priority should be to extend and strengthen the embargo. But America needs a backup plan t...
