Unmasking Misinformation: Journalist’s Quest for Verified Truth (International Edition)

The Journalists as Fact Checkers workshop, organised by the Friedrich Naumann Foundation for Africa for the Womentorship Champions, recently, was an unexpected catalyst for my growth as a female human rights defender. It effortlessly merged with my duties as both a journalist and an advocate, highlighting how journalism serves as a crucial act of service against misinformation. In Zimbabwe, where confirming straightforward facts such as fatality counts from road accidents can be difficult because of restricted access to data, fact-checking goes beyond being just part of one’s job; it transforms into a nuanced but important mode of defiance. One powerful takeaway was learning about “lateral reading,” which pushed me to go deeper than just skimming content and succumbing to click temptations. This change in mindset has provided me with a persistent critical outlook, examining each headline through the meticulous gaze of an investigator. Rather than taking information at ...

Giant, Cat-Sized Flying Squirrels Soared Over North America 4.75 Million Years Ago

A huge flying squirrel as big as a house cat glided through the air above Southern Appalachia about 4.75 million years ago.

This reveals the findings of a group of paleontologists from East Tennessee State University (ETSU) and the Autonomous University of Barcelona (UAB) in Spain.

In their research, the scientists detailed a newly discovered fossil specimen of the enormous flying squirrel. Miopetaurista webbi Recently discovered at a remarkably well-preserved prehistoric site called the Gray Fossil Site, situated in Washington County, Tennessee.

Despite its size, the team explained, the giant squirrel would have weighed in at only around three pounds, helping it to glide and giving it agility as it skittered across the tree tops.

Contrary to what one might expect, however, Miopetaurista is not closely related to the squirrels currently found in North America; instead, they share more similarities with the giant flying squirrels from China, Indonesia, and Japan.

"Envisioning enormous flying squirrels soaring above rhinos and mastodons inhabiting Tennessee’s woodlands 5 million years past is truly astonishing," stated paper author Joshua Samuels from ETSU in a release.

"This really points to the potential of the Gray Fossil Site to keep surprising us after 25 years."

Miopetaurista Specimens have previously been discovered in China, France, and Germany during the Miocene and Pliocene epochs, which spanned from approximately 23.03–5.33 million years ago for the former and 5.33–2.58 million years ago for the latter.

"Finding Miopetaurista "In North America, this discovery was quite surprising since this genus is solely documented in Eurasia," stated Isaac Casanovas-Viler, a co-author of the UAB paper, in an official release.

Some unclear reports came out of Florida, however, the discovery at the Gray Fossil Site brought forth fresh data and assisted in verifying that these enormous gliding rodents managed to traverse the Bering Land Bridge along with various other creatures approximately 5 million years ago.

This land bridge is hypothesized to have linked North America with Asia at various points in the past.

When Miopetaurista arrived in what we now know of as Tennessee, the researchers explained, the world was much warmer than it is today.

This climate supported dense, humid forests—in fact evidence for such, in the form of plant fossils, has also been found at the Gray Fossil Site—that would have allowed the critter to cross into North America, gliding from tree to tree.

Such agreeable conditions, however, were not to last for poor Miopetaurista .

"The cooling climate during the Pleistocene Ice Ages trapped these large flying squirrels in warmer sanctuaries such as Florida, which eventually played a role in their demise," stated lead author Montserrat Grau-Camats from UAB in a press release.

"The last American Miopetaurista lived millions of years after all Eurasian species of this genus had gone extinct, which means they were considered 'living fossils' at that time."
