Neanderthals and humans interbred for approximately 7,000 years, according to a recent study.

This extended period of genetic exchange left a lasting mark on the genomes of modern Eurasians, who carry a small percentage of Neanderthal DNA. The study, published in Nature, analyzed ancient and modern human DNA to provide a more precise timeline for interbreeding between Neanderthals and Homo sapiens.

This interbreeding, which began around 50,500 years ago and lasted approximately 7,000 years, left a lasting impact on the genomes of modern Eurasians.

The study examined DNA from 58 ancient human remains found across Eurasia, along with present-day human genomes. This analysis revealed an average date of 47,000 years ago for Neanderthal-Homo sapiens interbreeding, refining previous estimates.

The findings also suggest that the initial migration of modern humans out of Africa into Eurasia was largely complete by 43,500 years ago.

Have you ever wondered what could have caused the mighty Megafauna of the Americas to vanish? Picture this: in 2015, farmer James Bristle stumbled upon a nearly complete mammoth skeleton in Chelsea, Michigan, dating back a staggering 11,000 to 15,000 years. This remarkable discovery reignited interest in the Younger Dryas Impact Theory, which suggests that a cosmic collision—a comet or asteroid—struck the Earth around 12,800 years ago, resulting in a sudden and dramatic cooling of the climate. Such an impact may have unleashed a cascade of catastrophic environmental changes, including devastating wildfires and widespread habitat destruction, paving the way for the extinction of these colossal creatures. Yet, despite the intrigue surrounding this theory, the precise cause of their demise remains a tantalizing mystery, with scientists continuing to debate and delve deeper into the shadows of history.

Baljenac, a small uninhabited island located in the Šibenik archipelago of Croatia, is renowned for its striking resemblance to a giant fingerprint, created by an intricate network of stone walls built by local farmers in the 1800s. Covering an area of just 0.14 square kilometers, the island’s walls, if connected, would stretch for an impressive 23 kilometers (14 miles). Farmers from the neighboring island of Kaprije once used Baljenac for agriculture, clearing the island’s harsh vegetation to grow fig and citrus trees, along with grapevines. To protect their crops from the wind and divide the land into plots, they constructed waist-high stone walls using the ancient technique of dry stone walling, which involves skillfully stacking and interlocking rocks without the use of mortar.

The Arch of Titus (Italian: Arco di Tito; Latin: Arcus T**i) was built in honor of the victory (triumph) of Emperor Titus in Judea and the conquest of Jerusalem. The arch is single-passage and is 15.4 m high. It is richly covered with reliefs. Under the arch passes the main street of the Roman Forum - Via Sacra. It was built by Emperor Domitian shortly after the death of his older brother Titus in 81 to commemorate the conquest of Jerusalem in 70. Inside the arch, on one side, Emperor Titus is depicted in a chariot crowned as victorious. the other, the b***y of plundered Jerusalem.

White Pocket, a striking area within the Vermilion Cliffs National Monument in Arizona. 🇺🇸

The formations are primarily composed of Navajo Sandstone, originating from ancient sand dunes that were petrified over many millennia.

Erosion by wind and water has since sculpted these rocks into bizarre and intricate shapes, creating a landscape with swirling patterns and unusual textures.

The resulting appearance is reminiscent of an extraterrestrial surface, contributing to White Pocket’s otherworldly and mesmerizing appeal.

Devils Tower, located in northeastern Wyoming, is a dramatic geological formation that rises nearly 1,267 feet above the surrounding landscape. This massive monolithic butte, composed of igneous rock, features striking vertical grooves and a towering pillar-like appearance. Formed about 50 million years ago, Devils Tower is thought to be the eroded remnant of a volcanic intrusion, with its distinctive columns.

Beyond its geological intrigue, Devils Tower holds significant cultural importance. Native American legends from multiple tribes describe the tower as the result of a dramatic escape from giant bears. According to these stories, the ground rose to save a group of girls from the bears, leaving deep claw marks on the rock.

Today, the tower is regarded as a sacred site, where rituals and offerings are made by local tribes. While a popular climbing destination, a voluntary climbing ban in June respects these cultural traditions. Devils Tower continues to captivate with its blend of natural beauty and cultural richness, standing as a powerful symbol of both geological and spiritual significance.

The Leaning Tower of Pisa, built as a bell tower, began construction in 1173. By 1178, as the third floor was completed, builders noticed the structure tilting. The issue lay in its 3-meter foundation, set on soft clay and sand that couldn’t support its weight. Rather than abandon the project, they adjusted the upper floors to counterbalance the tilt, giving the tower its distinctive curve.
Over time, the lean increased as the foundation continued to settle unevenly. Despite this, the tower remained standing, thanks to the slow, 199-year construction process, which allowed the soil to stabilize, and the clay foundation, which absorbed seismic shocks. By 1990, the tilt reached 5.5 degrees, prompting fears of collapse. Restoration efforts between 1993 and 2001 reduced the tilt to 3.97 degrees, securing its future.
Today, over 600 years since its completion, the Leaning Tower of Pisa stands as a unique piece of medieval architecture and a popular tourist destination.

The world's largest aircraft prepares to take off.
Airlander 10, a spectacularly huge, helium-pumped aircraft, is unveiled fully assembled for the first time, in a giant aviation hangar near London.
The Airlander 10 is a hybrid airship, achieving lift, and thereby flight, via both aerostatic and aerodynamic forces. Unlike most airship designs, it does not have a circular cross-section, having adopted an elliptical shape with a contoured and flattened hull.
This shaping is deliberate so that it acts as a lifting body, contributing aerodynamic lift while the airship is in forward motion; generating up to half of the airship's lift in a similar manner to that of a conventional fixed-wing airplane.
Buoyancy is also provided by helium contained within the envelope, the pressure from which maintains the airship's unique shape. Between 60 percent and 80 percent of the aircraft's weight is supported by the lighter-than-air helium.

Noah Rediscovered: The Astonishing 6,500-Year-Old Relic from the Great Flood
An incredible find has come to light at the Penn Museum in Philadelphia—a remarkably preserved human skeleton, affectionately referred to as ""Noah,"" that dates back an astounding 6,500 years. This extraordinary artifact has remained untouched in a wooden box for 85 years. It was first discovered by the esteemed archaeologist Sir Leonard Woolley during his prominent excavations in the ancient city of Ur, which is now located in modern-day Iraq, between the years 1929 and 1930. Surprisingly, this significant piece was thought to be lost until its recent rediscovery.
Woolley’s excavations at Ur are particularly famous for unveiling the legendary Mesopotamian “royal cemetery,” which included hundreds of graves and 16 lavishly decorated tombs. Nonetheless, his team also uncovered burial sites that were approximately 2,000 years older than these royal interments.
Located nearly 50 feet (15 meters) below the surface of Ur, the excavation team identified 48 graves from the Ubaid period, which spans roughly from 5500 B.C. to 4000 B.C. Understanding the value of these ancient remains, Woolley carefully extracted one skeleton, encasing the bones and surrounding soil in wax before meticulously packing them for shipment to London, ultimately arriving in Philadelphia.
