The UK government has introduced an AI-driven crime prediction tool that identifies individuals deemed “high risk” for potential violence based on personal histories such as mental health and addiction, representing a controversial new development.
Meanwhile, in Argentina, authorities are launching an Artificial Intelligence Unit for Security aimed at utilizing machine learning for predicting crime and monitoring in real-time. In Canada, cities like Toronto and Vancouver employ ClearView AI’s predictive policing systems alongside facial recognition technology. In several U.S. cities, AI facial recognition is integrated with street surveillance to identify suspects.
The notion of predicting violence mimics the vision presented in Minority Report, which is compelling; however, …
The mystery of how the Egyptian pyramids were built has puzzled researchers for centuries. Constructed over 4,000 years ago as burial sites for pharaohs, there are still over 100 pyramids remaining. The largest, the Great Pyramid of Giza, originally stood at 147 meters (482 feet) in height.
Comprised of around 2.3 million stone blocks, each weighing between 2.5 and 15 tonnes, the construction required innovative methods to transport and lift the heavy stones. Different theories exist among scientists regarding the techniques used to achieve such great heights,” says Dr. Eman Ghoneim, a Professor at the University of North Carolina Wilmington in the United States.

Recent research has shed light on some aspects of pyramid construction. One prevailing theory suggests the use of ramps to move the stones, supported by the discovery of sloped structures near some pyramids. Dr. Roland Enmarch, a Senior Lecturer in Egyptology at the University of Liverpool, and his team unearthed groundbreaking evidence of quarry ramps in eastern Egypt used in pyramid construction.
Construction schedules were also crucial in the building of pyramids. It is believed that the Great Pyramid of Giza took 20 years to complete, starting at the beginning of a pharaoh’s reign. Archaeologist Frank Müller-Römer has proposed various ramp designs for pyramid construction, emphasizing the importance of multiple ramps placed along the exterior of the structure.
Construction Schedule
Various techniques like levers, cranes, and pulleys were likely employed in addition to ramps. In a study by Xavier Landreau and his team in Paris, a hydraulic lift system was proposed as a method to build the Step Pyramid of King Djoser. However, some experts question the feasibility of such systems based on archaeological evidence.
Research using scanning techniques is ongoing to explore the internal structure of the Great Pyramid of Giza. The ScanPyramids project by teams from Egypt and France aims to uncover hidden spaces within the pyramid using advanced imaging technologies.
Identifying Supply Lines
Transporting materials to the construction site was a logistical challenge. Researchers like Dr. Ghoneim and his team used satellite images and ground surveys to uncover ancient tributaries of the Nile River that were crucial for transporting goods to the pyramids. These discoveries shed light on the transportation methods used by ancient Egyptians.
Archaeologists have also unearthed logbooks detailing the construction activities at the Great Pyramids of Giza, dispelling myths of supernatural involvement. Ongoing excavations of workers’ quarters near the pyramids provide insight into the organizational aspects of pyramid construction.

The area of water between Florida, Puerto Rico, and Bermuda became notorious in the mid-20th century due to stories of mysterious disappearances of boats and planes.
A well-known incident occurred in 1945 when Flight 19, a group of five U.S. Navy bombers, vanished in the region. Over the years, wrecks and crashes in the Bermuda Triangle were often linked to supernatural forces.
In 1975, Larry Kush published a book debunking legends about the triangle, revealing inaccuracies and concluding that incidents in the area were not significantly higher than in other ocean regions.
Despite various theories proposed over the years, explanations range from natural phenomena like methane bubbles to supernatural causes like parallel worlds.
Some suggest that methane bubbles from the ocean floor caused ships to capsize, but research has shown no significant methane emissions in the area in the past 15,000 years.
The frequency of hurricanes in the region could have led to disasters before accurate weather forecasts were available, resulting in ships sinking due to high, rough waves.
While some blame magnetic anomalies for navigation errors, no such anomalies have been observed, though the alignment of true and magnetic north may have caused confusion in the past.
Despite the lack of identified dangers by the U.S. Coast Guard, and no statistically unusual number of incidents in the Bermuda Triangle, the mystery persists due to early reports receiving widespread attention.
Modern technology has enabled better tracking of air and sea traffic, reducing the sensationalism surrounding the Bermuda Triangle in recent years.
This article responds to the question posed by Cardiff resident Diane Johnston: “What happened in the Bermuda Triangle?”
