in Science. Back in 2021, researchers published work in which they used radiocarbon dating of crushed seeds of Ruppia cirrhosa, an aquatic grass, to date the preserved footprints to between 23,000 and 21,000 years old, which would make them thousands of years older than the next most recent evidence of humans in North America. That findi

Now, theyve done it: a group, including members of the previous collaboration, has dated pollen and sediments from the site to the same timeframe as the ancient grasses. Footprints are a telltale sign of a hominin presence, if not Homo sapiens. In 2020, a team found fossilized footprints in Saudi Arabia that

But the prints could also have belonged to Neanderthals, whose oldest confirmed footprints date to just over 100,000 years ago and were spotted on a Spanish beach in 2020. But the White Sands footprints are arguably more controversial than the prints from the Middle East and Europe. These belonged

Additionally, to ensure that people arent forced to constantly see a tweet after reporting it, Twitter will start hiding potentially offending content with a new notice like the one pictured above.

Twitters new guidelines come after聽new rules regarding how Twitter handles spam accounts and widespread criticism that social media companies need to do more to protect their users from various forms of online attacks and harassment. However, the reasoning beh

Either way, this isnt the last time Twitter will need to update its policies to better serve its users. But hopefully, by making it easier to hide offensive tweets and see when people violated its polices, Twitter will be a slightly more civilized, transparent place. [Engadget]
