many people know African roots of the human family tree.

But recent discoveries of fossils and DNA across Asia are forcing a fundamental rethinking of our family history.

It was there that a whole new breed of extinct humans was unearthed, including some nicknamed relatives. little hobbit and the burly dragon man – The same goes for the three little pigs painted on the cave walls. The oldest figurative art in the world.

Get ready to be blown away this week by another tantalizing fossil discovery from the region that reveals just how sophisticated and knowledgeable our ancient ancestors really were. .

In a remote cave on Indonesia’s Borneo island, archaeologists have made a discovery that upends our understanding of the Stone Age. It’s an amputee who lived 31,000 years ago.

The skeleton of the young individual had lost the left lower limb. a surprisingly skilled prehistoric surgeonprobably using stone tools.

just a century Previously, most people who underwent an amputation would have died from blood loss or shock or subsequent infection.

Studies show that not only was this Stone Age surgery successful, but amputated patients lived an additional 6 to 9 years, eventually dying of natural causes before being carefully buried by their caregivers.

Scientists at the University of Cambridge in the UK created an artificial mouse embryo in a laboratory dish. This is an exciting advance that could eventually lead to new fertility treatments.

without using sperm or egg, researchers say Embryo developing a beating heart and brain from mouse stem cells.

By observing embryos at this stage in the lab rather than in the womb, scientists have better understood the puzzling process, learned why pregnancies fail and how to prevent this loss.

They hope to move from mouse embryos to creating models of spontaneous pregnancy. Many of them fail in the early stages.

The shrew-like Brasilodon quadrangularis lived 225 million years ago.

Brasilodon quadrangularis, the earliest mammal known to science, was a shrew-like creature. 225 million years ago, we gliding under the feet of the first dinosaurs.

If you make a mistake in your identity, the researcher I used to think I was a small animal was a reptile.

Now, new research reveals Thanks, it was “definitely” a mammal Clues Provided by Three Fossilized Jawbones It belonged to a long-extinct creature.

The discovery will help paleontologists better understand the evolution of modern mammals.

What happened to NASA’s Artemis I mission after two failed Mega Moon rocket launches?

space agency Deferred the third attempt until September 23rd or September 27th – Or it could be longer as engineers find ways to fix hydrogen fuel leaks.

Complicating matters are Florida’s variable weather, hurricane season in full swing, and existing efforts. NASA Crew 5 mission to carry a new team of astronauts to the International Space Station aboard a SpaceX rocket on October 3.

For now, the moon The rocket remains on the launch pad while engineers replace the seal in the interface between the liquid hydrogen supply line and the launcher.

In February 2019, the U.S. Antarctic Program research vessel Nathaniel B. Palmer works along the edge of the Thwaites Eastern Ice Shelf.

Located in West Antarctica, Thwaites Glacier, sometimes referred to as the ‘end of the world glacier’, has for decades worried scientists who fear extreme sea-level rise associated with its possible collapse.

Geophysicists have mapped the historical retreat of a Florida-sized glacier in hopes of learning from the past what might happen in the future.

The researchers found that at some point in the last two centuries, the glacier floor was breaking away from the ocean floor and retreating at twice the rate scientists observed over the past decade.

Findings suggest that glaciers have the ability to retreat rapidly once they retreat past seafloor ridges, thus helping to keep them in check. more simply It’s holding up ‘with its claws,’ as explained by a marine geophysicist involved in the study.
