Returning with precautions isn’t returning without risk. About 100 children under age 15 died in the US from Covid-19 in 2020. And there are still unknowns, such as the long-term effects of the disease on kids, including the inflammatory illness known as MIS-C, says Ashleigh Tuite, an… Click here to view the original article.
India’s Desperate Fend for Themselves Amid Covid Mismanagement
In early medieval Italy (then a troubled peninsula transitioning from the collapse of Roman rule) a group of monks at a mountaintop monastery had a water problem.

In October 2010, severe thunderstorms pummeled the desert city of Phoenix with multiple tornadoes and massive hailstones up to 5 centimeters in diameter. In a few short hours, the storm exacted a heavy toll in the form of $2.7 billion of property damage almost entirely the result of… Click here to view the […]
The lowest level of the atmosphere, the troposphere, contains almost all of Earth’s weather. In the stratosphere above, moisture drops to almost zero. The boundary that separates these two layers—the tropopause—is defined as the point at which water… Click here to view the original article.

Sometimes crazy things happen—so crazy they don’t even seem real. Last week, Phillies right fielder Bryce Harper was warming up before a game with some practice bats. He hit a nice line drive, and then it collided with another ball in midair. That gives us some fun physics to unpack. Let’s… Click here to view […]

Curves in the fabric of space-time tell planets and people which way to fall, while all the other forces spring from quantum particles. Albert Einstein first spoke of gravity in terms of […]
