A reservoir computing system for multimode and multiscale signal processing can be created using optoelectronic synapses that are based on α-In2Se3 and exploit the tightly coupled ferroelectric and optoelectronic properties of the material.

The Biden administration plans to announce awarding more than $6 billion to Samsung to expand its chip output in Texas, two sources said.

Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering.

An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state—an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.

Researchers have discovered two techniques that could enable attackers to bypass audit logs or generate less severe entries when downloading files from SharePoint.

Microsoft SharePoint is a web-based collaborative platform that integrates with Microsoft Office and 365, primarily as a document management and data storage system.

Many companies use it for document management and collaboration, creating websites and corporate intranets, automating complex workflows, and enterprise content management applications.

“For the first time we have physical evidence showing us what was happening in the moon’s interior during this critical stage in its evolution, and that’s really exciting,” said Dr. Jeff Andrews-Hanna.

Our Moon has long been hypothesized to have formed from a planet-sized object colliding with the Earth. But, what happened after and how can its unique geologic exterior and interior be explained? This is what a recent study published in Nature Geoscience hopes to address as an international team of researchers led by the Lunar and Planetary Laboratory (LPL) at the University of Arizona used a combination of spacecraft data and computer models to investigate the geologic processes that led to heavier elements being present on the nearside of the Moon, which is constantly facing Earth due to being tidally locked with our planet. This study holds the potential to help researchers better understand the geologic mechanisms behind planetary formation and could lead to gaining greater insight into how rocky planets like Earth and Mars formed.

For the study, the researchers used data from NASA’s GRAIL mission, which was used to map gravitational anomalies on the Moon, and computer models to determine the distribution of ilmenite, a combination of titanium and iron, across the Moon’s nearside and how much sunk into the Moon’s interior during the Moon’s formation and evolution. It has been previously hypothesized that while ilmenite sunk to the Moon’s interior early on, portions of it returned to the surface from volcanism, and the mechanisms behind these events have led scientists puzzled.

When I was a kid, I went to a science camp, and one of the instructors showed us a few inches of fiber optic cable. I remember thinking it was so neat that you could light it up at one end, and no matter how you twisted the cable, you could see the light come out on the other end. At the time, I thought how useful it might be to send Morse code through it—I was very young. Things have changed a bit since then. Today, UK Aston University researchers sent data at a 301 terabits per second (Tbps) clip over existing fiber networks.

How fast is that? It’s about 1.2 million times faster than the US’ medium fixed broadband speed of 242.48 megabits per second (Mbps). Or, it’s fast enough to deliver 1,800 4K movies to your home in a second. And I thought my recent home internet fiber upgrade to 2 Gigabits per second (Gbps) was impressive!Of course, no one will get 301 Tbps speeds in their home office. In the real world, I know a handful of people with 10 Gbps connections to their houses and many data centers with 40 Gbps local area networks.

Team presents new path to long-term data storage based on atomic-scale defects.

With the development of the internet, social media, and cloud computing, the amount of data created worldwide on a daily basis is skyrocketing. This calls for new technologies that could provide higher storage densities combined with secure long-term data archiving far beyond the capabilities of traditional data storage devices. An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) now proposes a new concept of long-term data storage based on atomic-scale defects in silicon carbide, a semiconducting material. These defects are created by a focused ion beam, providing high spatial resolution, fast writing speed, and low energy for storing a single bit, as the team reports in the journal Advanced Functional Materials.

Latest estimates assume around 330 million terabytes of new data created each day, with 90 percent of the world’s data generated in the last two years alone. If the sheer numbers already suggest the need of advanced data storage technologies, it is by no means the only problem associated to this development. “The limited storage time of current storage media requires data migration within several years to avoid any data loss. Besides of being trapped in perpetual data migration procedures, this substantially increases the energy consumption, because a significant amount of energy is consumed in the process,” says Dr. Georgy Astakhov from the Institute of Ion Beam Physics and Materials Research at HZDR.
