While humans evolved over a period of approximately 6 million years, breakthroughs in modern medicine as we know it today got going only in the 19th and 20th centuries. So how did humans successfully survive through millions of years of diseases and illnesses without modern drugs and treatments?
The horrors of war are all too familiar: lives lost, homes destroyed, entire communities forced to flee. Yet as time passes, places that once were sites of death and destruction can become peaceful natural refuges.
People are social creatures. While many of us are making the best of social isolation, we’re much better together than apart. This is especially true with music that we create collectively – everything from jam bands and choruses to orchestras.

The ingredients for life are spread throughout the universe. While Earth is the only known place in the universe with life, detecting life beyond Earth is a major goal of modern astronomy and planetary science.
The James Webb Space Telescope team has released the first science-quality images from the new telescope. In them are the oldest galaxies ever seen by human eyes, evidence of water on a planet 1,000 light-years away and incredible details showing the birth and death of stars. Webb’s purpose is to explore origins – of the universe, of galaxies, of stars and of life – and the five images released on July 12, 2022, make good on that promise.
At first glance, it may seem as though Big Tech can’t figure out how to make money off its foray into podcasting.
In early May 2022, Meta announced that it was abruptly ending Facebook’s podcast integration less a year after it launched. Facebook had offered podcasters the ability to upload their shows to the social media site.

In a recent interview, Adams discussed his belief that New York City has a “special energy” because it sits atop a store of rare gems and stones – the so-called “Manhattan schist,” which is over 450 million years old and contains over 100 minerals.
In Baz Luhrmann’s “Elvis,” there’s a scene based on actual conversations that took place between Elvis Presley and Steve Binder, the director of a 1968 NBC television special that signaled the singer’s return to live performing.
Charles J. Russo, University of Dayton The U.S. Supreme Court has consistently banned school-sponsored prayer in public schools. At the same time, lower courts have generally forbidden public school employees from openly praying in the workplace, even if no students are involved. Yet on June 27, 2022, the Supreme Court effectively gave individual employees’ prayerContinue reading “Why the Supreme Court’s football decision is a game-changer on school prayer”
