‘Flying car’ makes Tokyo debut at international tech event

Posted by in categories: government, transportation

A “flying car” took to the air in Tokyo for the first time on Friday during an international event showcasing cutting-edge technology.

About 500 spectators applauded as the vehicle hovered around 10 meters off the ground in a parking lot outside the Tokyo Big Sight convention center in the capital’s Koto Ward for SusHi Tech Tokyo 2024.

Flying vehicles are expected to become part of the next generation of human transportation and will be effective in dealing with traffic congestion and delivering supplies to disaster areas, the Tokyo metropolitan government and other organizers said.

TMSC Announces Low-Power N4e Node, Says It’s Boosting Specialty Nodes by 50%

Posted by in categories: business, energy

It’s unclear what customers or applications might be earmarked for this node, but it’s possible it could be dedicated to IoT and other consumer devices that need to sip power. Typically, these applications use legacy nodes as it would be too expensive to use advanced processes for inexpensive devices, but TSMC is planning for the future since this effort won’t be realized until 2029 or so.

TSMC’s Dr. Kevin Zhang, senior vice president of business development and overseas Operations, says the company has already started building Greenfield, but he didn’t indicate where it’s located. He says the rapid deployment of the Greenfield fab is the first time the company has essentially skipped what we assume is a lengthy review process and put shovels in dirt already.

According to Zhang, TSMC’s move is part of its larger effort to build some resiliency into its global supply chain. That resiliency will be achieved both by building fabs outside of Taiwan and increasing capacity for nodes it thinks will be in demand in the future. Anandtech notes the company’s most advanced low-power node is currently N6e, which is a 6nm/7nm node that uses between 0.4V and 0.9V. For N4e, the company is reportedly looking to drop that all the way down to 0.4V, but it didn’t offer any additional details about its performance or attributes at the symposium.

Ed Boyden: Let’s Bring Engineers into Studying the Brain

Posted by in categories: genetics, neuroscience

I met Prof. Ed Boyden at last year’s Global Future 2045 conference in New York. There I was highly impressed with Boyden’s impressive work in neuroscience in general and optogenetics in particular, as well as the profound implications it would have on our ability to understand and manipulate the brain. And so I knew instantly I must bring him for an interview.

The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal

Posted by in category: materials

In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction.

Deep-sea sponge’s ‘zero-energy’ flow control could inspire new energy efficient designs

Posted by in categories: chemistry, computing, engineering, space

Now, new research reveals yet another engineering feat of this ancient animal’s structure: its ability to filter feed using only the faint ambient currents of the ocean depths, no pumping required.

This discovery of natural ‘“zero energy” control by an international research team co-led by University of Rome Tor Vergata and NYU Tandon School of Engineering could help engineers design more efficient chemical reactors, air purification systems, heat exchangers, hydraulic systems, and aerodynamic surfaces.

In a study published in Physical Review Letters, the team found through extremely high-resolution how the skeletal structure of the Venus flower basket sponge (Euplectella aspergillum) diverts very slow deep sea currents to flow upwards into its central body cavity, so it can feed on plankton and other marine detritus it filters out of the water.
