Adult-made neurons mature longer, have unique functions

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

The challenge of measuring adult neurogenesis is difficult, but it’s not impossible. A big part of the solution is knowing what to measure and where. While this new study was performed on rats—and therefore may be a poor predictor of what we’ll see in humans—it can direct future research by showing neuroscientists where to look and what to look for.

And unlike the hard problem of consciousness, unraveling the mysteries of adult neurogenesis may have clinical applications. Better the lifecycle of neurons may reveal how neurological disorders such as Parkinson’s and Alzheimer’s disease emerge. There’s even research linking disorders such as depression and anxiety to neurogenesis activity.

US surgeons perform world’s first whole eye transplant

Posted by in categories: biotech/medical, innovation

A team of surgeons in New York has performed the world’s first transplant of an entire eye in a procedure widely hailed as a medical breakthrough, although it isn’t yet known whether the man will ever see through the donated eye.

The groundbreaking surgery involved removing part of the face and the whole left eye—including its blood supply and optic nerve—of a donor and grafting them onto a lineworker from Arkansas who survived a 7,200-volt electric shock in June 2021.

Aaron James, 46, suffered extensive injuries including the loss of his left eye, his dominant left arm above the elbow, his nose and lips, front teeth, left cheek area and chin.

A24’s Making an Elon Musk Biopic Directed by Darren Aronofsky

Posted by in categories: business, Elon Musk, space travel, sustainability

Elon Musk is getting the Hollywood treatment. Variety reports that indie movie studio A24 has won the rights to adapt Walter Isaacson’s recent biography about the business magnate, with “Black Swan” and “Requiem for a Dream” director Darren Aronofsky slated to direct. There’s no official word on who’s playing Musk yet, though there’s plenty of wild suggestions online.

According to the report, studios were embroiled in “heated competition” for Isaacson’s latest book, which was released this September. The author’s last biography on a tech titan, Steve Jobs, was also adapted into a movie of the same name in 2015. Of course, the main attraction here is Musk, whose penchant for controversy is matched only by his enormous popularity.

New algorithm finds failures and fixes in autonomous systems, from drone teams to power grids

Posted by in categories: drones, information science, robotics/AI

From vehicle collision avoidance to airline scheduling systems to power supply grids, many of the services we rely on are managed by computers. As these autonomous systems grow in complexity and ubiquity, so too could the ways in which they fail.

Now, MIT engineers have developed an approach that can be paired with any , to quickly identify a range of potential failures in that system before they are deployed in the real world. What’s more, the approach can find fixes to the failures, and suggest repairs to avoid system breakdowns.

The team has shown that the approach can root out failures in a variety of simulated autonomous systems, including a small and large network, an aircraft collision avoidance system, a team of rescue drones, and a robotic manipulator. In each of the systems, the new approach, in the form of an automated sampling algorithm, quickly identifies a range of likely failures as well as repairs to avoid those failures.

Probing the intricate structures of 2D materials at the nanoscale

Posted by in categories: computing, nanotechnology, particle physics

Two-dimensional (2D) materials, composed of a single or a few layers of atoms, are at the forefront of material science, promising revolutionary advancements in technology. These ultra-thin materials exhibit unique and exotic properties, particularly when their layers are stacked and twisted in specific ways.

This manipulation of layers can significantly alter their electronic characteristics, presenting exciting opportunities for the development of next-generation technologies such as more efficient computers and reliable electricity storage systems.

Understanding the intricate relationship between the atomic structure and electronic properties of these materials, however, poses a significant challenge. Traditional microscopy techniques struggle to capture the complete 3D atomic structure of these layered materials, especially when the layers are oriented differently or composed of light elements.

Squeezing the Universe: LIGO Breaks the Quantum Limit

Posted by in categories: quantum physics, space

In 2015, the Laser Interferometer Gravitational-Wave Observatory, or LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.
