Some EV owners in the Sunshine State are reporting having to buy tires after just 5,000 to 7,000 miles of driving.
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.
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.”
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 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.

“Our modeling suggests that shallow moonquakes capable of producing strong ground shaking in the south polar region are possible from slip events on existing faults or the formation of new thrust faults,” said Dr. Thomas R. Watters.
Objects expand and contract from heating and cooling, and planetary objects are no different, which includes our nearest celestial neighbor, our Moon. Billions of years ago, the Moon was very volcanically active which caused it to expand from all the internal heat driving the volcanic activity. However, as this internal heat died down, the Moon began to cool, and has been contracting, or shrinking, ever since. Now, a recent study published in The Planetary Science Journal discusses how this shrinkage could be responsible for the lunar south pole becoming warped, leading to landslides and moonquakes, which increases safety risks for future astronauts, specifically with NASA’s Artemis program.
For the study, the researchers developed models of how seismic waves from moonquakes could cause powerful ground shaking and landslides near the lunar south pole, which is home to de Gerlache scarp, with a scarp being a geologic feature formed from the Moon contracting. Data from the Apollo Passive Seismic Network, which were a series of seismometers left on the lunar surface during Apollo 11, 12, 14, 15, and 16 and functioned between 1969 and 1977, indicates that de Gerlache scarp could have formed from an approximate magnitude-5.3 moonquake. The reason de Gerlache scarp is a crucial location is due to its proximity to one of the potential landing sites for the Artemis III mission, which is slated to be the first human landing of the Artemis program.
