A 3D printed ‘metamaterial’ boasting levels of strength for weight not normally seen in nature or manufacturing could change how we make everything from medical implants to aircraft or rocket parts.

RMIT University researchers created the new metamaterial—a term used to describe an with not observed in nature—from common titanium alloy.

But it’s the material’s unique lattice structure design, recently revealed in the journal Advanced Materials, that makes it anything but common: tests show it’s 50% stronger than the next strongest alloy of similar density used in aerospace applications.

When red giant stars run out of helium fuel and expel their outer layers to become hot, compact white dwarf stars that are roughly the size of Earth, planetary nebulae are created. As the carbon-enriched shed material is gradually blasted into the interstellar medium, it produces magnificent patterns.

The majority of planetary nebulae are circular, but others, like the well-known “Butterfly Nebula,” have an hourglass or wing-like appearance. These structures are thought to be the consequence of the material expanding into two lobes or “wings” due to the gravitational attraction of a second star circling the parent star of the nebula. The wings develop over time without altering their initial form, much like an expanding balloon.

Key Takeaways:

Within this system, two young stars engage in an intimate celestial waltz, while a third star pirouettes around the pair. Enveloping all three stars is a fragmented disk of dust and gas, a cosmic canvas where future planets may take shape. This disk, unlike the one that gave rise to our solar system’s planets, comprises three loops, each with its unique contortions — a middle ring distinctly warped, and an inner ring playfully askew in relation to its companions.

On Wednesday, February 21st, at 01:40 p.m. PST (04:40 p.m. EST), an interesting package returned to Earth from space.

This was the capsule from the W-1 mission, an orbital platform manufactured by California-based Varda Space Industries, which landed at the Utah Test and Training Range (UTTR). Even more interesting was the payload, which consisted of antiviral drugs grown in the microgravity environment of Low Earth Orbit (LEO).

The mission is part of the company’s goal to develop the infrastructure to make LEO more accessible to commercial industries.

A privately built spacecraft on the moon has beamed back new photos from the lunar surface, showing the vehicle’s much-celebrated descent and the moments immediately after touchdown when it tipped over on its side.

The Odysseus lander, built by Houston-based Intuitive Machines, landed on the moon on Feb. 22, making history as the first commercial craft to reach the lunar surface and the first U.S. spacecraft on the moon in more than 50 years.

The following day, Intuitive Machines said Odysseus had pitched over when it touched down near a crater called Malapert A, close to the moon’s south pole. Company officials said the 14-foot-tall lander was operational but that some of the spacecraft’s antennas were pointing at the ground, limiting its ability to communicate with flight controllers back on Earth.

While Artificial Intelligence (AI) focuses on simulating and surpassing human intelligence, Artificial Life (A-Life) takes a different approach. Instead of replicating cognitive abilities, A-Life seeks to understand and model fundamental biological processes through software, hardware, and even… wetware.

Forget Turing tests and chess games. A-Life scientists don’t care if their creations are “smart” in the traditional sense. Instead, they’re fascinated by the underlying rules that govern life itself. Think of it as rewinding the movie of evolution, watching it unfold again in a digital petri dish.
