The U.S. Navy is testing out a new solution to the age-old problem of prepping for painting. Instead of chipping, sandblasting or hydroblasting, it is adopting technology from the aerospace sector: laser ablation.

Teams at Puget Sound Naval Shipyard are already using a laser paint stripping system that was originally developed by Missouri-based tech company Adapt Laser for use on aircraft components. The device peels off rust, paint, oil and other contaminants without leaving any residue or damaging the substrate. Instead of a dust of chips, rust and blasting grit on the surface, it leaves clean and ready-to-paint bare steel, according to the Navy.

7th Fleet’s shipyard at Yokosuka (Ship Repair Facility and Japan Regional Maintenance Center, or SRF-JRMC) is looking at bringing laser ablation into its yard in order to improve conditions for its workforce and accelerate its workflow. When considering prep time, the stripping process and post-stripping cleanup, laser ablation may be faster than some traditional surface preparation processes, according to Naval Sea Systems Command (NAVSEA).

Scientists from Russia and Switzerland have probed into nanostructures covering the corneas of the eyes of small fruit flies. Investigating them the team learned how to produce the safe biodegradable nanocoating with antimicrobial, anti-reflective, and self-cleaning properties in a cost-effective and eco-friendly way. The protection coating might find applications in diverse areas of economics including medicine, nanoelectronics, automotive industry, and textile industry. The article describing these discoveries appears in Nature.

Scientists from Far Eastern Federal University (FEFU, Russia) teamed up with colleagues from University of Geneva, The University of Lausanne, and Swiss Federal Institute of Technology in Zurich for an interdisciplinary research project during which they were able to artificially reproduce the nanocoating of the corneas of fruit flies (Drosophila flies) naturally designed to protect the eyes of the insects from the smallest dust particles and shut off the reflection of light.

The craft of nanocoating meets demands in various fields of economics. It can wrap up any flat or three-dimensional structure, and, depending on the task, give it anti-reflective, antibacterial, and hydrophobic properties, including self-cleaning. The latter, for example, is a very important feature for expensive reusable overnight ortho-k lenses that correct the eyesight. Similar anti-reflective coatings are already known though created by more complex and costly methods. They are being used on the panels of computers, glasses, paintings in museums can be covered with them in order to exclude reflection and refraction of light.

AMD has filed a patent for something that everyone knew would eventually happen: an MCM GPU Chiplet design. Spotted by LaFriteDavid over at Twitter and published on Freepatents.com, the document shows how AMD plans to build a GPU chiplet graphics card that is eerily reminiscent of its MCM based CPU designs. With NVIDIA working on its own MCM design with Hopper architecture, it’s about time that we left monolithic GPU designs in the past and enable truly exponential performance growth.

AMD patents GPU chiplet design for future graphics cards

The patent points out that one of the reasons why MCM GPUs have not been attempted in the past is due to the high latency between chiplets, programming models and it being harder to implement parallelism. AMD’s patent attempts to solve all these problems by using an on-package interconnect it calls the high bandwidth passive crosslink. This would enable each GPU chiplet to communicate with the CPU directly as well as other chiplets via the passive crosslink. Each GPU would also feature its own cache. This design appears to suggest that each GPU chiplet will be a GPU in its own right and fully addressable by the operating system.

Researchers from Yokohama National University in Japan have developed a prototype microprocessor using superconductor devices that are about 80 times more energy efficient than the state-of-the-art semiconductor devices found in the microprocessors of today’s high-performance computing systems.

As today’s technologies become more and more integrated in our daily lives, the need for more is ever increasing. Because of this increase, the of that increasing computational power is growing immensely. For example, so much energy is used by modern day data centers that some are built near rivers so that the flowing water can be used to cool the machinery.

“The digital communications infrastructure that supports the Information Age that we live in today currently uses approximately 10% of the global electricity. Studies suggest that in the , if there is no fundamental change in the underlying technology of our communications infrastructure such as the computing hardware in large data centers or the electronics that drive the communication networks, we may see its electricity usage rise to over 50% of the global electricity by 2030,” says Christopher Ayala, an associate professor at Yokohama National University, and lead author of the study.

While many institutions are developing quantum computers, making a quantum internet requires a way to transfer the information between computers. This is accomplished by a phenomenon called quantum teleportation, in which two atoms separated by large distances are made to act as if they are identical.

Don Lincoln writes about recent research that has brought us closer to actualizing the goal of a quantum internet, giving us both hope and fear about what it could mean for the future.

This will help ensure that SSDs don’t suddenly just stop working one day. 😃 At least you get to back up your data.

It’s only available for data centers for now though. In the future, we may get our own when they perfect the technology.

If a NAND chip fails, these new SSDs detect it, move the data somewhere else on the drive, and keep on functioning.

Digital data storage is a growing need for our society and finding alternative solutions than those based on silicon or magnetic tapes is a challenge in the era of “big data.” The recent development of polymers that can store information at the molecular level has opened up new opportunities for ultrahigh density data storage, long-term archival, anticounterfeiting systems, and molecular cryptography. However, synthetic informational polymers are so far only deciphered by tandem mass spectrometry. In comparison, nanopore technology can be faster, cheaper, nondestructive and provide detection at the single-molecule level; moreover, it can be massively parallelized and miniaturized in portable devices. Here, we demonstrate the ability of engineered aerolysin nanopores to accurately read, with single-bit resolution, the digital information encoded in tailored informational polymers alone and in mixed samples, without compromising information density. These findings open promising possibilities to develop writing-reading technologies to process digital data using a biological-inspired platform.

DNA has evolved to store genetic information in living systems; therefore, it was naturally proposed to be similarly used as a support for data storage (1–3), given its high-information density and long-term storage with respect to existing technologies based on silicon and magnetic tapes. Alternatively, synthetic informational polymers have also been described (5–9) as a promising approach allowing digital storage. In these polymers, information is stored in a controlled monomer sequence, a strategy that is also used by nature in genetic material. In both cases, single-molecule data writing is achieved mainly by stepwise chemical synthesis (3, 10, 11), although enzymatic approaches have also been reported (12). While most of the progress in this area has been made with DNA, which was an obvious starting choice, the molecular structure of DNA is set by biological function, and therefore, there is little space for optimization and innovation.
