Indian Firm Helped Build World’s 1st Fusion Reactor For Endless Clean Energy

Posted by in categories: futurism, nuclear energy

Larsen & Toubro has finished the construction of 3,800-tonne ITER cryostat — the world’s largest steel vacuum chamber and a critical part of the ITER machine — for world’s first fusion reactor as a source of endless clean energy. The company says that the final components are ready to ship to the project site in France and here is what it means for the future of humanity.

Nvidia brings Ampere A100 GPUs to Google Cloud

Posted by in categories: innovation, robotics/AI

Just over a month after announcing its latest generation Ampere A100 GPU, Nvidia said this week that the powerhouse processor system is now available on Google Cloud.

The A100 Accelerator Optimized VM A2 instance family is designed for enormous artificial intelligence workloads and . Nvidia says users can expect substantive improvements over previous processing models, in this instance up to a 20-fold performance boost. The system maxes out at 19.5 TFLOPS for single-precision performance and 156 TFLOPS for AI and computing applications demanding TensorFloat 32 operations.

The Nvidia Ampere is the largest 7 nanometer chip ever constructed. It sports 54 billion transistors and offers innovative features such as multi-instance GPU, automatic mixed precision, an NVLink that doubles GPU-to-GPU direct bandwidth and faster memory reaching 1.6 terabytes per second.

NASA’s new gecko-robot can climb just about everything like the lizard’s feet

Posted by in categories: internet, robotics/AI, space

What is more powerful than suction cup and even a vacuum pump, but was not invented by humans?

Answer: a gecko’s foot. NASA has decided to copy the lizard’s incredible gripping technology, which relies on electrostatic attractions, in its Gecko Gripper robot. This is not coming from an internet troll trying to sell car insurance. The space agency partnered with OnRobot, which specializes in finger-like robotic grippers, to create a device that can (so far) lift 14 pounds. The radiation-resistant pads could literally mean a huge step forward for getting around in space.

Scientists have discovered a new physical paradox

Posted by in category: futurism

Researchers from the Peter the Great St. Petersburg Polytechnic University (SPbPU) have discovered and theoretically explained a new physical effect: amplitude of mechanical vibrations can grow without external influence. The scientific group offered their explanation on how to eliminate the Fermi-Pasta-Ulam-Tsingou paradox.

The scientists of SPbPU explained it using a simple example: to rock a swing, you have to keep pushing it. It is generally believed that it is impossible to achieve oscillatory resonance without constant external influence.

However, the scientific group of the Higher School of Theoretical Mechanics, Institute of Applied Mathematics and Mechanics SPbPU discovered a new physical phenomenon of ‘ballistic resonance,” where mechanical oscillations can be excited only due to internal thermal resources of the system.

This Quantum Random Number Generator Can Never Be Hacked

Posted by in categories: computing, quantum physics

But, he added, the method took about 10 minutes to produce 1,024 random strings, whereas current cryptographic processes would need far faster number generators.

The new technique’s first real-world use will come when it’s incorporated into NIST’s randomness beacon, a public source of randomness for researchers studying unpredictability, Bierhorst said.

But he added that he hopes the experimental setup could one day be shrunk enough to fit on a computer chip and help in the creation of “unhackable” messages.

Common Molecular Feature of Antibodies That Neutralize SARS-CoV-2 Discovered, Boosting COVID-19 Vaccine Prospects

Posted by in category: biotech/medical

The findings support many vaccine strategies being used to tackle the new coronavirus.

A team led by scientists at Scripps Research has discovered a common molecular feature found in many of the human antibodies that neutralize SARS-CoV-2, the coronavirus that causes COVID-19.

The scientists, whose study appears today (July 13, 2020) in Science, reviewed data on nearly 300 anti-SARS-CoV-2 antibodies that their labs and others have found in convalescent COVID-19 patients over the past few months. They noted that a subset of these antibodies is particularly powerful at neutralizing the virus — and these potent antibodies are all encoded, in part, by the same antibody gene, IGHV3-53.
