Four different measurement tools

Intrigued by the idea that the stone camels might constitute an artistic breakthrough, the aforementioned team of archaeologists — once again headed by Charloux, alongside archeologist Maria Guagnin — tried to see if they could assess their age not through stylistic comparisons but a “technological study” that yielded absolute results, using a variety of measurement tools to determine them.

In October 2017, the interstellar object ‘Oumuamua passed through our solar system, leaving many questions in its wake. Not only was it the first object of its kind ever observed, but the limited data astronomers obtained as it shot out of our solar system left them all scratching their heads. Even today, almost five years after this interstellar visitor made its flyby, scientists are still uncertain about its true nature and origins. In the end, the only way to get real answers from ‘Oumuamua is to catch up with it.

Interestingly enough, there are many proposals on the table for missions that could do just that. Consider Project Lyra, a proposal by the Institute for Interstellar Studies (i4is), which would rely on advanced propulsions technology to rendezvous with interstellar objects (ISOs) and study them. According to their latest study, if their mission concept launched in 2028 and performed a complex Jupiter Oberth maneuver (JOM), it would be able to catch up to ‘Oumuamua in 26 years.

UK start-up Urban-Air Port (UAP) has announced plans to establish 200 hubs for flying taxis and cargo drones across 65 cities globally over the next five years.

The firm is set to launch its first ‘vertiport’, dubbed the “worlds smallest airport”, in Coventry in April, and says a “significant investment” from Hyundai Motor Group’s urban air division Supernal will enable expansion to further sites.

Samsung, the world’s biggest memory chip maker, has announced that it has become the first in the world to demonstrate the MRAM (Magnetoresistive Random Access Memory) technology for in-memory computing. The company’s paper on its innovation, titled ‘A crossbar array of magnetoresistive memory devices for in-memory computing,’ was published by Nature on its website, and its print edition is coming next.

The research was a collaboration between SAIT (Samsung Advanced Institute of Technology), Samsung Foundry, and Samsung Semiconductor R&D. Dr. Seungchul Jung (Staff Researcher at SAIT), Dr. Donhee Ham (Fellow of SAIT and Professor of Harvard University), and Dr. Sang Joon Kim (Vice President of Technology at SAIT) worked on the research.

Usually, data is stored in memory chips (DRAM) and processed by a CPU or an AP (Application Processor). However, data storage and computing happen on the same chip with in-memory computing. Since there is no need to transfer data from memory to the processor and vice versa, a lot of time is saved. Data processing inside the memory happens in a highly parallel manner, resulting in substantial power savings. Samsung claims that MRAM technology will be great for things like AI processing.

ASML President and CTO Martin van den Brink said:

“Intel’s vision and early commitment to ASML’s High-NA EUV technology is proof of its relentless pursuit of Moore’s Law. Compared to the current EUV systems, our innovative extended EUV roadmap delivers continued lithographic improvements at reduced complexity, cost, cycle time and energy that the chip industry needs to drive affordable scaling well into the next decade.”

Intel plans to start high-volume manufacturing (HVM) in 2025, which is also when the company will be using its 18A (1.8nm) fabrication technology. To do so, Intel has been experimenting for quite a while when it first obtained ASML’s Twinscan EXE:5000, which was the industry’s first EUV scanner with a 0.55 numerical aperture. Today, the company ordered ASML’s next-generation High-NA tool, the Twinscan EXE:5200.

Machines can now distinguish between 12 different types of plastic, thanks to a new camera system developed in Denmark.

More than 200,000 new high-tech small and medium-sized enterprises (SMEs) will be cultivated by the end of 2025 as China strives to foster a favorable environment for the growth of such firms, according to a notice recently issued by the Ministry of Science and Technology.

China will, in particular, boost the development of innovative sci-tech SMEs featuring key technologies, research personnel, high-value intellectual property rights and high research input, according to the notice.

More efforts will be made to support high-tech SMEs to generate innovation as well as introduce domestic and global talents by optimizing related policies and injecting diverse resources, the notice added.

A single injection of a newly developed drug has been shown to reverse paralysis in mice with severe spinal cord injuries. By mimicking the extra-cellular matrix around the spine, the liquified drug promotes the regeneration of severed nerves and the repair of other vital tissues, allowing the rodents to regain the ability to walk within four weeks.

Describing this breakthrough in a new study in the journal Science, researchers explain how they injected synthetic nanofibers into the damaged tissue of mice 24 hours after making a cut in their spinal cords. Consisting of an array of peptides, these nanofibers quickly assemble into a gel around the wound and begin communicating with cells in order to promote healing.
