Shortages of basic goods still plague the U.S. economy — 2 1/2 years after the pandemic's onset turned global supply chains upside down. Want a new car? You may have to wait as long as six months, depending on the model you order. Looking for a spicy condiment? Supplies of Sriracha hot sauce have been running dangerously low. And if you feed your cat or dog dry pet food, expect empty shelves or elevated prices.
Some of the greatest scientific discoveries haven't resulted in Nobel Prizes. Louis Pasteur, who lived from 1822 to 1895, is arguably the world's best-known microbiologist. He is widely credited for the germ theory of disease and for inventing the process of pasteurization — which is named after him — to preserve foods. Remarkably, he also developed the rabies and anthrax vaccines and made major contributions to combating cholera.
For decades, practitioners of radiocarbon dating have exploited a signal dubbed the "silver lining" of atomic weapons tests conducted in the 1950s. As blast debris mushroomed into the air, particles of radioactive carbon-14 entered the atmosphere. This fallout created the so-called bomb pulse. The atmospheric carbon-14 concentration spiked during the 1950s and early 1960s, followed by a gradual decline after the Limited Test Ban Treaty was signed in 1963.
In countries such as the U.K., U.S. and Canada, ultra-processed foods now account for 50 percent or more of calories consumed. This is concerning, given that these foods have been linked to a number of different health conditions, including a greater risk of obesity and various chronic diseases such as cardiovascular disease and dementia.

Almost everyone has a can opener available to open a can but it's way more convenient if that can comes with a pull tab. So, why do some cans have them and not others?. The story goes that in 1959, a humble engineer from Dayton, Ohio, named Ermal "Ernie" Fraze was enjoying a family picnic when he realized that he forgot to bring a "church key." A church key is an old-school can opener that, in the era before pull-tab cans, was used to pop two holes in a can of beer.
Most of us are taught from a young age that birds "fly south for the winter," and although that is technically true, it is a gross oversimplification of an incredibly complex process. In North America alone, there are around 900 species of birds, an estimated 75 percent of which migrate. That's a whole lot of wing-flapping going on when the weather turns cool.
The title of oldest tree in the world is, surprisingly enough, up for grabs. Since about 2018, a majestically gnarled bristlecone pine in California has held the designation, only to be usurped by a new up-and-comer discovered on a Swedish mountaintop. Not to be outdone, a controversial find in a Chilean forest has tree aficionados wondering whether an ancient cypress could actually be hundreds — yes, hundreds — of years older than any known living tree in existence.
It's hard to imagine life on Earth without the moon overhead each night. Though the moon seems an omnipresent object in the night sky, it actually goes through a number of phases and has a unique set of steps in the celestial dance of our solar system. If you've ever...
