An exploration of Frank Herbert’s implicit and explicit warnings against the unmitigated advancement and dependence on AI (Artificial Intelligence), while also examining how these fundamental concerns, leading to AI’s prohibition, consistently resonate throughout the series. One of its less explored, but equally compelling, elements is its commentary on the rise of artificial intelligence. Dune is set in the far future taking place in an interstellar empire that is devoid of thinking machines after a universal ban against computing technology that is made in the likeness of a human mind. The reasons behind this prohibition not only serve as a caution against the perils of artificial intelligence, but they also underscore broader warnings present throughout Herbert’s Dune books.

Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team, led by researchers in Lund, has spent a hundred million computer hours over eight years trying to correct these.

The last decade has seen major advances in computer simulations that can realistically calculate how galaxies form. These cosmological simulations are crucial to our understanding of where galaxies, stars, and planets come from. However, the predictions from such models are affected by limitations in the resolution of the simulations, as well as assumptions about a number of factors, such as how stars live and die and the evolution of the interstellar medium.

Collaborative Efforts Enhance Accuracy

SpaceX is gearing up for its third attempt to get its massive Starship spacecraft into orbit. In a recent update, the company hinted at a March 14 launch “pending regulatory approval.”

Meanwhile, SpaceX CEO Elon Musk is already thinking many steps ahead, envisioning what’ll be like to travel on board the spacecraft all the way to Mars.

“Starship will have a small spin on the way to Mars,” Musk replied after Id Software founder John Carmack suggested SpaceX should try to spin its Dragon astronaut shuttle to test out spin gravity. “Even a tiny gravity vector is better than none.”

Starship will attempt a controlled reentry as well as the first re-light of a Raptor engine. It could fly again next week.

Alef Aeronautics has announced that its revolutionary Model A flying car has now received 2,850 pre-orders for a total of $850 million.

The demonstration of a device that can triple the number of photons in a microwave signal is a key step toward making a single-microwave-photon detector.

The ability to detect a single microwave photon’s worth of energy remains beyond the capability of any tool in the photonics toolbox. Detectors for one photon’s worth of energy at other photon wavelengths mostly identify the energy via the electrical signals that the photons induce after they hit the detector and are converted into electrons. However, the energies of microwave photons are too low for this process to work effectively. Fortunately, superconducting circuits provide a platform for turning one microwave photon into many, making such photons easier to detect. In a joint effort, researchers at Grenoble Alpes University in France and at the University of Sherbrooke in Canada have now demonstrated a device that can multiply the photons in a weak microwave signal [1]. The demonstration provides a key first step in creating a single-microwave-photon detector.

While detectors for optical photons have existed for decades, scientists only started developing detectors for microwave photons in the past 15 years. The wish list for an effective microwave-photon detector is daunting: it should respond to traveling photons, and not only those localized in space [2– 5]; it should have sufficient sensitivity to register a signal from a single photon [6]; it should be able to count how many photons are in a signal [7]; it should not register so-called dark counts, hits recorded when the microwave source is off; and finally, its lag time between detections should be as short as possible. One proposed way to achieve these goals is to build a microwave-photon detector using the photon-number multiplier that Romain Albert and colleagues have now demonstrated [1, 8].

American astronauts aren’t heading back to the moon just yet. NASA’s pricey Artemis mission is facing technical challenges. The space agency is now working with both SpaceX and Blue Origin.

CAPE CANAVERAL, Florida, March 3 (Reuters) — A SpaceX rocket safely lifted off from Florida on Sunday night carrying a crew of three U.S. astronauts and a Russian cosmonaut on their way to the International Space Station (ISS) to begin a six-month science mission in Earth orbit.

The two-stage Falcon 9 rocket topped with an autonomously operated Crew Dragon capsule dubbed Endeavor was launched from NASA’s Kennedy Space Center at Cape Canaveral, along Florida’s Atlantic coast, at 10:53 p.m. EST (0353 GMT Monday).

A live NASA-SpaceX webcast showed the 25-story-tall rocketship ascending from the launch tower as its nine Merlin engines roared to life in billowing clouds of vapor and a reddish fireball that lit up the night sky. The rocket consumes 700,000 gallons of fuel per second during launch, according to SpaceX.

SpaceX’s next Starship to fly has passed a critical fueling test, setting the stage for a highly anticipated third launch attempt of the world’s biggest rocket.

The gleaming, stainless-steel Starship rocket and its Super Heavy booster, which together stand 400 feet tall (122 meters), were filled with more than 10 million pounds of liquid methane and liquid oxygen propellant during the recent launch dress rehearsal, which was performed at SpaceX’s Starbase facility near Boca Chica Beach in southern Texas.
