Astrophysicists design ‘radically different’ world map

You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round. Source: https://earthsky.org/earth/astrophysicists-new-design-world-map…

The Fed’s System That Allows Banks To Send Money Back and Forth is Down

The Federal Reserve’s system that allows financial institutions to send money back and forth electronically went down Wednesday morning. From a report: The “operational error,” as the Fed described it, impacted multiple services, including its pivotal automated clearinghouse system, which connects depository and related institutions send electronic credit and debt transfers. There were no initial indications that foul play was suspected….

Blueprint for fault-tolerant qubits

Building a universal quantum computer is a challenging task because of the fragility of quantum bits, or qubits for short. To deal with this problem, various types of error correction have been developed. Conventional methods do this by active correction techniques. In contrast, researchers led by Prof. David DiVincenzo from Forschungszentrum Jülich and RWTH Aachen University, together with partners from the…

What is the Milky Way?

When someone says “Milky Way,” do you think of the starry pathway across our sky, or of the great pinwheel-shaped galaxy in space? Both are correct! Source: https://earthsky.org/astronomy-essentials/what-is-the-milky-way-galaxy…

Microsoft’s Big Win in Quantum Computing Was an ‘Error’ After All

In a 2018 paper, researchers said they found evidence of an elusive theorized particle. A closer look now suggests otherwise. From a report: In March 2018, Dutch physicist and Microsoft employee Leo Kouwenhoven published headline-grabbing new evidence that he had observed an elusive particle called a Majorana fermion. Microsoft hoped to harness Majorana particles to build a quantum computer, which promises…

The Problems of Touchscreens In the F-35 Joint Strike Fighter

Long-time Slashdot reader AmiMoJo quotes a recent blog post from BoingBoing: The F-35 Joint Strike Fighter is the most crammed-with-digital-tech fighter jet in history, the product of a multi-decade, trillion-dollar design process that has been famously messy. But the jet is out there, and pilots are flying it. One big design shift with the F-35 is that it removes many of…

A benchmark for single-electron circuits

Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, meaning that deviations from error-free operation still occur—albeit (in the best possible scenario) only very rarely. Thus, insights into both the physical origin and the metrological aspects of this fundamental uncertainty…

Myopia Correcting ‘Smart Glasses’ From Japan To Be Sold in Asia

Can a pair of unique spectacles banish nearsightedness without surgical intervention? Japan’s Kubota Pharmaceutical Holdings says its wearable device can do just that, and it plans to start releasing the product in Asia, where many people grapple with myopia. From a report: The device, which the company calls Kubota Glasses or smart glasses, is still being tested. It projects an image…

Scientists Use Satellite Imagery To Count Elephants

Scientists from a trio of universities have combined satellite imagery with deep learning to detect elephants from space. The goal is to help protect these endangered species from poachers or habitat destruction. Their study was published in the journal Ecology and Conservation. Interesting Engineering reports: The team’s method proved comparable to human detection accuracy and could help solve a number of…
