The identities of the occupants of the unspoiled 4th-century BCE Royal Tombs at Vergina in northern Greece have been identified

The burials contain the remains of Alexander’s father, stepmother, half-siblings, and son, along with armor and other items belonging to the man himself.

While there is never been any doubt that the human skeletal remains found in Royal Tombs I, II, and III belong to close relatives of Alexander, scholars have spent almost half a century bickering over who exactly lies within each grave.

The researchers examined the skeletal elements with the aid of macrophotography, radiographs, and anatomical dissection. The study authors combined osteological analyses, macro photography, X-rays, and anatomical dissections of the ancient remains with historical sources from the ancient past.

NASA’s Perseverance rover confirms presence of ancient lake on Mars and it may hold clues to past life

Evidence of ancient lake sediments at the base of Mars’ Jezero Crater offer new hope for finding traces of life in samples collected by NASA’s Perseverance rover.

Perseverance touched down on Feb. 18, 2021 inside the Red Planet’s 28-mile-wide (45 kilometers) Jezero Crater, which is believed to have once hosted a large lake and river delta. The rover has been scouring the crater in search of signs of past life and collecting and caching dozens of samples along the way for a possible future return to Earth.

MIT researchers’ new rapid liquid printing technique is 10x faster

Imagine printing a table leg or a chair frame in minutes using liquid metal. Researchers from MIT have developed a new additive manufacturing technique that can do just that.

Their technique, called liquid metal printing (LMP), involves depositing molten aluminum along a predefined path into a bed of tiny glass beads. The aluminum quickly hardens into a 3D structure, ready to be used or further processed.

Liebherr converted this massive mining excavator to electric power

For the first time in the company’s 40-year history, Liebherr have converted one of their R 9,400 excavators from a conventional diesel to an electric powertrain.

The re-powered mining machine was commissioned at Fortescue’s Christmas Creek mine site in Western Australia – but what’s more significant is that the conversion was done during the standard service life of the machine.

“The modular design of Liebherr equipment makes it possible to repower existing diesel excavators to new zero emission configurations, such as electric powertrains,” explains Oliver Weiss, Executive Vice President of R&D, Engineering, and Manufacturing for Liebherr Mining. “This means that the diesel equipment customers buy today is also future-proofed for many years to come. The fact that we can ease the transition from traditional to decarbonized mining fleets for our customers is one of the key strategies of the Liebherr Zero Emission Mining Program.”

Ingenuity Mars Helicopter: A Journey Beyond Expectations Comes to a Close

The Little Helicopter That Could, also known as NASA’s Ingenuity Mars Helicopter, has unfortunately ended its mission of exploring the surface of Mars after a historic 72 flights since its first flight in April 2021. The decision to end the mission came after teams discovered that at least one rotor blade was damaged enough to where it could no longer perform aerial duties. Despite this, Ingenuity remains standing upright and communicating with Earth continues, as well.

“The historic journey of Ingenuity, the first aircraft on another planet, has come to end,” NASA Administrator Bill Nelson said in a statement. “That remarkable helicopter flew higher and farther than we ever imagined and helped NASA do what we do best – make the impossible, possible. Through missions like Ingenuity, NASA is paving the way for future flight in our solar system and smarter, safer human exploration to Mars and beyond.”

Launched onboard NASA’s Perseverance rover on July 30, 2020, and landing in Jezero Crater on Mars on February 18, 2021, Ingenuity became the first aircraft to perform a powered flight on another world on April 19, 2021. Ingenuity was originally built for a 30-day mission where it would conduct five experimental flights to demonstrate that powered flight could be achieved on another planetary body other than Earth. With a total of 72 flights under its belt, Ingenuity has far exceeded expectations in terms of its original goals and objectives. This includes a horizontal flight distance of 2,315 feet (705 meters), which was accomplished just last month on December 20, 2023.

Permutation City by Greg Egan [2/2] FULL AUDIOBOOK

“Permutation City” by Greg Egan explores the nature of reality, consciousness, and existence. Set in a future where people can upload their consciousness into virtual realities, known as “Autoverse.” A software engineer, René Barjavel, becomes embroiled in a complex and mind-bending exploration of identity and the nature of existence as he grapples with the implications of living in a world where reality itself may be a simulation.
