Whole Foods shoppers can now pay with palm scans

Posted by in categories: food, mobile phones, privacy

Amazon is bringing its palm print-scanning biometric payment technology to several Whole Foods locations.

Biometrics: Every person has measurable physical characteristics that are unique to them — and because these attributes are unique and measurable, they can be used to verify our identity.

Biometric technologies — like the one that probably unlocks your phone — automate this verification, analyzing a face, fingerprint, or palm for distinct identifiers linked to a specific person.

A crystal shape conundrum is finally solved

Posted by in categories: chemistry, materials

A crystal’s shape is determined by its inherent chemistry, a characteristic that ultimately determines its final form from the most basic of details. But sometimes the lack of symmetry in a crystal makes the surface energies of its facets unknowable, confounding any theoretical prediction of its shape.

Theorists at Rice University say they’ve found a way around this conundrum by assigning arbitrary latent energies to its surfaces or, in the case of two-dimensional materials, its edges.

Yes, it seems like cheating, but in the same way a magician finds a select card in a deck by narrowing the possibilities, a little algebraic sleight-of-hand goes a long way to solve the problem of predicting a crystal’s shape.

Air Force Research Lab awards $76 million for lunar experimentation

“Our primary goals for the program are to advance techniques to detect previously unknown objects through search and discovery, to detect small or distant objects and to study spacecraft positioning and navigation in the [beyond GEO] realm,” Oracle’s principal investigator James Frith said in a Nov. 10 statement.

The contract for Oracle, which was previously named the Cislunar Highway Patrol System, comes amid a growing interest in the cislunar environment and increasing concerns about potential deep-space threats from adversaries like China. In response, AFRL and other stakeholders are crafting a classified roadmap that lays out the cislunar capabilities various space agencies are pursuing.

AFRL expects Oracle to launch in 2025 and have a two-year mission life. Along with tracking and detecting new objects, the satellite will inform a separate AFRL effort to develop a green propellant to power space vehicles. The satellite will carry a refueling port for the Advanced Spacecraft Energetic Non-Toxic program.

Volumetric Bioprinter 3D Prints Liver Organoids in Less than 20 Seconds

Posted by in categories: 3D printing, bioprinting

Volumetric 3D printing is an exciting technology that could lead to extremely rapid production of 3D printed parts by curing every particle of the object at once. Now, researchers from Utrecht University are applying the process to bioprinting and have 3D printed functioning liver units at centimeter scale in less than 20 seconds. The results were published in Advanced Materials.

How generative AI could create assets for the metaverse

Posted by in categories: biotech/medical, robotics/AI

Check out the on-demand sessions from the Low-Code/No-Code Summit to learn how to successfully innovate and achieve efficiency by upskilling and scaling citizen developers. Watch now.

The metaverse skyrocketed into our collective awareness during the height of the pandemic, when people longed for better ways to connect with each other than video calls. Gaming’s hot growth during the pandemic also pushed it forward. But the metaverse became so trendy that it now faces a backlash, and folks aren’t talking about it as much.

Yet technologies that will power the metaverse are speeding ahead. One of those technologies is generative AI, which uses deep learning neural networks to produce creative concept art and other ideas based on simple text prompts.
