UC Berkeley physicist Norman Yao first described five years ago how to make a time crystal—a new form of matter whose patterns repeat in time instead of space. Unlike crystals of emerald or ruby, however, those time crystals existed for only a fraction of a second.

But the time has arrived for time crystals. Since Yao’s original proposal, new insights have led to the discovery that time crystals come in many different forms, each stabilized by its own distinct mechanism.

Using new quantum computing architectures, several labs have come close to creating a many-body localized version of a time crystal, which uses disorder to keep periodically-driven quantum qubits in a continual state of subharmonic jiggling—the qubits oscillate, but only every other period of the drive.

The equivalent of cheap 100-inch binoculars will soon be possible. This memo is a quick update on seven rapidly converging technologies that augur well for astronomy enthusiasts of the near future. All these technologies already exist in either fully developed or nascent form, and all are being rapidly improved due to the gigantic global cell phone market and the retinal projection market that will soon replace it. Listed here are the multiple technologies, after which they are brought together into a single system.

1) Tracking.
2) Single-photon image sensing.
3) Large effective exit pupils via large sensors.
4) Long exposure non-photographic function.
5) Flat optics (metamaterials)
6) Off-axis function of flat optics.
7) Retinal projection.

With a minimalistic design and H-shaped front panel, the new mtu hydrogen fuel cell is a complete solution for power supply in the megawatt range that will be produced in series from 2025. This modern-looking module will in the future deliver a net power output of around 150 kW – sufficient to power approximately ten homes. It can also be connected together into scalable fuel cell power plants with outputs in the megawatt range – capable of providing clean backup power for large data centers.

The fuel cell module is the result of collaboration between Rolls-Royce and cellcentric, a joint venture company set up by Daimler Truck AG and Volvo Group AB earlier this year. It is based on cellcentric’s fuel cell modules that emit nothing other than water vapor. This will enable CO2-free, climate-neutral generation of emergency power for data centers.

“Electrical generators based on fuel cells represent the next leap forward in the energy transition, both for our customers and us,” said Andreas Schell, CEO of Rolls-Royce Power Systems. “That’s why we’re investing a three-digit million amount in R&D over the next few years, and we hope that this strong commitment will encourage governments and politicians to promote and support this pioneering, extremely climate-friendly technology. When they run on green hydrogen, meaning hydrogen made using renewable energy sources, fuel cells are climate-neutral. For this reason, and also because we’re simply convinced by fuel cell technology, we also want to look into how green hydrogen can be produced cost-effectively in the quantities we need.”

AMD Unveils Zen 4 CPU Roadmap: 96-Core 5nm Genoa in 2,022 128-Core Begamo in 2023.

AMD shared its Zen 4 CPU roadmap, which includes the 96-core Genoa and 128-core Begamo CPUs.

Wireless sensing devices, tools that allow users to sense movements and remotely monitor activities or changes in specific environments, have many applications. For instance, they could be used for surveillance purposes as well as to track the sleep or physical activities of medical patients and athletes. Some videogame developers have also used wireless sensing systems to create more engaging sports or dance-related games.

Researchers at Florida State University, Trinity University and Rutgers University have recently developed Winect, a new wireless sensing system that can track the poses of humans in 3D as they perform a wide range of free-form physical activities. This system was introduced in a paper pre-published on arXiv and is set to be presented at the ACM Conference on Interactive, Mobile, Wearables and Ubiquitous Technologies (Ubi Comp) 2,021 one of the most renowned computer science events worldwide.

“Our research group has been conducting cutting-edge research in wireless sensing,” Jie Yang, one of the researchers who carried out the study, told TechXplore. “In the past, we have proposed several systems to use Wi-Fi signals to sense various human activities and objects, ranging from large-scale human activities, to small-scale finger movements, sleep monitoring and daily objects For example, we proposed two systems dubbed E-eyes and WiFinger, which are among the first work to utilize Wi-Fi sensing to distinguish various types of daily activity and finger gestures.”

Consider the room you are sitting in: From the injection-molded plastic of a computer mouse to the synthetic carpet fibers on the floor, you are surrounded by petroleum-derived products in your daily life. But what if there is a better way to produce the products we depend on with cleaner and greener materials? Biomanufacturing offers a way to use materials from nature to create the items we use every day.

Checkerspot, a materials innovation company, is rethinking products from a molecular level. It is optimizing microbes to biomanufacture unique structural oils found in nature. The company has taken the technology it has built and turned it into a platform to bring us closer to a post-petroleum future.

Scientists at the University of Southampton have achieved a data storage breakthrough, offering intense density and long-term archiving capabilities. With this new data storage, you can easily store up to 500 terabytes on a single CD-sized disc. Whether the data is information from museums and libraries to a person’s DNA records, it can store it all and much more!

This technology is known as five-dimensional (5D) optical storage and was first demonstrated back in 2013 when scientists were successful in using it to record and retrieve a 300-kb text file. It might not seem like much, but at that time, it was a breakthrough in data storing technologies just like how floppy discs played the same part some thousand years ago.

The data is written using a femtosecond laser which emits short but powerful pulses of light, forging tiny structures in glass that are measured in nanoscale. These structures contain information on the intensity and polarization of the laser beam in addition to the 3D space, hence it is referred as 5D data storage.

How many bits does the universe contain? A lot.

A trippy new estimate calculates the total number of bits in the visible universe.

The world is hungry for semiconductors, and not all of them need to be made with cutting-edge technology. The race is on to find older machines that can still crank out chips.
