Mark Zuckerberg appeared to take a shot at Apple’s Vision Pro

Posted by in category: augmented reality

Meta CEO Mark Zuckerberg seemed to take a hit at Apple’s Vision Pro in Meta’s first-quarter earnings call on Wednesday.

Zuckerberg said he didn’t think augmented reality glasses would make it in the mainstream market until it had “full holographic displays.” The comment appears to show his skepticism of the potential success of a product like Apple’s Vision Pro.

MIT’s new 3D printer can create its own parameters so that users don’t have to

Posted by in categories: 3D printing, sustainability

A team of scientists have developed a new FDM 3D printer that can automatically create parameters for unknown materials.

Material presets for mass-manufactured polymers can be found on most 3D printers. However, the 3D printing parameters for sustainable and recycled materials need to be manually adjusted. This trial and error process can be frustrating and time-consuming, limiting the adoption of environmentally friendly filaments.

Experts from MIT’s Center for Bits and Atoms (CBA), the U.S. National Institute of Standards and Technology (NIST), and Greece’s National Center for Scientific Research (Demokritos) are working to change this.

Seeding the Stars

Posted by in categories: engineering, environmental, media & arts, space

The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long.

Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.

Unveiling Earth’s Ancient Shield: A 3.7-Billion-Year-Old Magnetic Record

Posted by in category: particle physics

“Extracting reliable records from rocks this old is extremely challenging, and it was really exciting to see primary magnetic signals begin to emerge when we analyzed these samples in the lab.” said Dr. Claire Nichols.

How long has the Earth’s magnetic field existed? This is what a recent study published in the Journal of Geophysical Research Solid Earth hopes to address as a team of international researchers discovered evidence indicating that the Earth’s magnetic field existed as far back as 3.7 billion years ago and was approximately half as strong as it is today, which puts this as the oldest evidence of Earth’s magnetic field to date. This study holds the potential to help scientists better understand the processes responsible for producing the Earth’s magnetic field, which is responsible for shielding the planet’s atmosphere and surface from harmful space weather.

For the study, the researchers analyzed iron-bearing rock formations among the Isua Supracrustal Belt in Southern West Greenland whose iron particles record the direction and strength of the magnetic field and are locked in time due to crystallization. In the end, the researchers determined that the iron particles exhibit evidence of the Earth’s magnetic field from 3.7 billion years ago along with its strength being half of what it is today.
