With more contagious coronavirus variants spreading, a simple cloth mask might not always be enough. Consumer Reports explains how to upgrade your mask.
More contagious variants of SARS-CoV-2 are now spreading in the U.S., with one potentially poised to become the predominant strain in this country by March, according to the Centers for Disease Control and Prevention.

They might be relatively small — even jumbo shrimp — but shellfish and crustaceans are valuable fisheries in North Carolina, worth millions of dollars each year.
North Carolina is home to numerous species of crustaceans and shellfish, in many shapes, sizes and colors. This is our first installment in an in-depth look at some of the more popular and interesting animals in this category that call coastal North Carolina home.
Crustaceans and shellfish do not put up a fight to catch them like most fish species. You do not need an expensive rod, reel or lures and most of them stay in the same location year-round and do not leave North Carolina waters.

On the bay this fall morning, there’s a wind-carved rim of ice and a gathering of floes. One male polar bear, bony after a season without seal blubber, struggles along the slushy edge, haunches soaked, nearly slipping into the sea.
We are on Gordon Point, in northern Manitoba, where Hudson Bay widens into its northwest crescent. Polar winds make it colder than at comparable latitudes, and the shallow waters of the bay freeze early. Having passed the summer months in the subarctic wild of Wapusk National Park to the south, polar bears now congregate here, waiting for the ice to come in.

A magnetic reversal 42,000 years ago helped bring about earthly extinctions, scientists said, accompanied by changes in the sky including electrical storms and widespread auroras.
A new international study suggests that a magnetic field reversal – combined with changing solar winds – contributed to an environmental crisis and mass extinctions 42,000 years ago. It happened around the time of the demise of the Neanderthals, an extinct human species that once roamed what’s now Europe, these scientists said, and it would have come with electrical storms, widespread auroras and an influx of cosmic radiation.
The Ingenuity helicopter, which landed on Mars this week via the Perseverance rover, runs a Qualcomm Snapdragon 801 processor, while the rover itself has similar power to early iMacs.
Mars has a new inhabitant: the Snapdragon.
The common Qualcomm Snapdragon processor, which powers most of the Android smartphones in the US, is running inside Ingenuity, an autonomous drone now on Mars, Qualcomm says. It arrived on the Red Planet yesterday via the Perseverance rover (which uses a processor similar to those you’d find in early iMacs), and will be our first attempt to fly something in the atmosphere of Mars.
An ancient, well-preserved tree that was alive the last time the Earth’s magnetic poles flipped has helped scientists pin down more precise timing of that event, which occurred about 42,000 years ago.
This new information has led them to link the flipping of the poles to key moments in the prehistoric record, like the sudden appearance of cave art and the mysterious extinction of large mammals and the Neanderthals. They argue that the weakening of the Earth’s magnetic field would have briefly transformed the world by altering its climate and allowing far more ultraviolet light to pour in.
