The CDC Used Their Research on School Openings, They Say -- And Got It Exactly Backward


(CDC)
A group of researchers actual scientists are saying the Centers for Disease Control and Prevention (CDC) misinterpreted their work and issued “harmful” guidance keeping school closed that their research never suggested was necessary.
In an op-ed published at USA Today, the researchers, Dr. Tara Henderson and Dr. Daniel Johnson of the University of Chicago, Dr. Monica Gandhi of the University of California-San Francisco and Dr. Tracy Tracy Beth Hoeg of the University of California-Davis, wrote that their data says schools “can remain fully open safely” and that the CDC got it wrong when they issued strict school lockdown guidelines suggesting it said otherwise. ....

Suspicions on True Origin of World's Oldest 'Impact Crater' Have Now Been Confirmed


Suspicions on True Origin of World s Oldest Impact Crater Have Now Been Confirmed
11 MARCH 2021
Earth and giant meteorites go way back, but new research confirms that what had been proposed as the oldest impact crater on the planet – the 100-kilometer (62-mile) wide Maniitsoq structure – isn t actually an impact crater at all.
 
Through a combination of field mapping, rock dating, and geological chemical analysis techniques, researchers have been able to show that features previously argued to be the faint signature of a long-eroded crater were anything but. The alleged structure is as much the product of the same geological processes as those that created the surrounding region. ....
