Engineering the Unbreakable: MIT’s Microscopic Metamaterials Defy Supersonic Impacts

Posted by in categories: engineering, space travel

High-speed experiments can help identify lightweight, protective “metamaterials” for spacecraft, vehicles, helmets, or other objects.

An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What’s more, the specific structure matters, with some being more resilient to impacts than others.

That’s what MIT engineers are finding in experiments with microscopic metamaterials — materials that are intentionally printed, assembled, or otherwise engineered with microscopic architectures that give the overall material exceptional properties.

MIT student creates device that is able to search the entire internet using just his mind

Posted by in categories: internet, wearables

A Massachusetts Institute of Technology (MIT) student has created a device that allows humans to communicate with machines using our minds — and it truly is incredible.

Arnav Kapur created a device called AlterEgo, which is a wearable type of headset that allows users to communicate with technology without even speaking a word.

So how does it work?

Einstein’s gravity and quantum mechanics united at last?

Posted by in category: quantum physics

“Our task,” Fedorov wrote, “is to make nature, the blind force of nature, into an instrument of universal resuscitation and to become a union of immortal beings.”

Fedorov’s writing never turned mainstream, but it did spawn a short-lived, visionary philosophical movement known as Cosmism. Materialized during the Industrial Revolution — a time of unprecedented societal change — the movement generally sought to redefine mankind’s relationship with technology and progress, with the ultimate goal of regulating the forces of nature so that humanity could achieve unity and immortality. The movement offered a more spiritual alternative to both futurism and communism.

Although the latter annihilated Cosmism before it had a chance to mature, its maxims have acquired new relevancy in the age of Big Tech. The following interview with Boris Groys, a distinguished professor of Russian and Slavic studies at New York University and editor of the new book Russian Cosmism, reveals why.

AI startup Magic is building a “superhuman software engineer”

Posted by in categories: robotics/AI, transportation

San Francisco-based startup Magic AI just secured more than $100 million in funding to develop an AI software engineer, which it sees as a milestone along the path to artificial general intelligence (AGI).

The background: Everything we see and do on our devices starts as code, and traditionally, that code was written by trained software engineers. In 2021, OpenAI disrupted this paradigm with CODEX, an AI that can write computer code in response to prompts written in natural language.

Accidental Deep Ocean Discovery Changes Our Understanding of Earth

Posted by in category: chemistry

Studying a rock is like reading a book. The rock has a story to tell, says Frieder Klein, an associate scientist in the Marine Chemistry & Geochemistry Department at the Woods Hole Oceanographic Institution (WHOI).

The rocks that Klein and his colleagues analyzed from the submerged flanks of the St. Peter and St. Paul Archipelago in the St. Paul’s oceanic transform fault, about 500 km off the coast of Brazil, tell a fascinating and previously unknown story about parts of the geological carbon cycle.

Transform faults, where tectonic plates move past each other, are one of three main plate boundaries on Earth and about 48,000 km in length globally, with the others being the global mid-ocean ridge system (about 65,000 km) and subduction zones (about 55,000 km).

A Prelude to Speech: How the Brain Forms Words

Posted by in categories: biotech/medical, cyborgs, neuroscience

Summary: Researchers made a groundbreaking discovery on how the human brain forms words before speaking. By utilizing Neuropixels probes, they’ve mapped out how neurons represent speech sounds and assemble them into language.

This study not only sheds light on the complex cognitive steps involved in speech production but also opens up possibilities for treating speech and language disorders. The technology could lead to artificial prosthetics for synthetic speech, benefiting those with neurological disorders.

Ultrasound Brain Stimulation: A Significant Leap in Neurotherapy

Posted by in category: neuroscience

New research conducted by a team led by Dr. PARK Joo Min of the Center for Cognition and Sociality within the Institute for Basic Science (IBS) unveils a novel technique that could transform the treatment landscape for brain disorders.

The team developed a non-invasive brain stimulation method called Patterned Low-Intensity Low-Frequency Ultrasound (LILFUS), which holds tremendous potential for inducing long-lasting changes in brain function.

Neural Decoding Unveils Secrets of Navigation

Posted by in categories: biological, military, robotics/AI

Summary: A new study combines deep learning with neural activity data from mice to unlock the mystery of how they navigate their environment.

By analyzing the firing patterns of “head direction” neurons and “grid cells,” researchers can now accurately predict a mouse’s location and orientation, shedding light on the complex brain functions involved in navigation. This method, developed in collaboration with the US Army Research Laboratory, represents a significant leap forward in understanding spatial awareness and could revolutionize autonomous navigation in AI systems.

The findings highlight the potential for integrating biological insights into artificial intelligence to enhance machine navigation without relying on GPS technology.
