The sawfish, a fish that looks like a hedge-trimmer, is at at risk of extinction

By Amy Woodyatt, CNN Researchers say the sawfish is on the verge of extinction. (CNN)The sawfish is one of the ocean s stranger sights with its unique long, narrow nose lined with teeth, it resembles a hedge-trimmer or chain saw. But the shark-like rays are on the brink of extinction, having vanished from half of the world s coastal waters, according to a new study. Sawfish were once found on the coastlines of 90 countries. But now they are some of the world s most threatened marine fish, and are already presumed extinct in some 46 countries, researchers from Canada s Simon Fraser University said.

Wall Street s coolest stocks can leave investors cold

Why Wall Street’s ‘coolest’ stocks can leave investors cold MarketWatch 2/9/2021 FA CENTER Wall Street’s most popular stocks are like the cool kids who won popularity contests in high school. Yet many researchers have found that the winners of those contests often end up living far more troubled lives than the rest of us. One famous study found that the coolest kids at age 13 had, by the time they reached 23, a 40% greater rate of alcohol and marijuana abuse and a 22% greater rate of adult criminal behavior. The analogy between cool kids and cool stocks is closer than you might think. Researchers have found that on average, the shares of the most-popular companies lag those of the least-popular companies.
