Dominance of γ-γ electron-positron pair creation in a plasma driven by high-intensity lasers

Posted by in category: quantum physics

Electron-positron pair generation from nonlinear quantum electrodynamics is predicted at high intensities that are, so far, beyond experimental capabilities. Here, simulations predict a high yield of positrons can be obtained from gamma-gamma photon collisions in the linear regime, using counter-propagating pulses and a microstructured target.

Hiding malware inside AI neural networks

Posted by in categories: cybercrime/malcode, robotics/AI

A trio of researchers at Cornell University has found that it is possible to hide malware code inside of AI neural networks. Zhi Wang, Chaoge Liu and Xiang Cui have posted a paper describing their experiments with injecting code into neural networks on the arXiv preprint server.

As grows ever more complex, so do attempts by criminals to break into machines running new technology for their own purposes, such as destroying data or encrypting it and demanding payment from users for its return. In this new study, the team has found a new way to infect certain kinds of computer systems running artificial intelligence applications.

AI systems do their work by processing data in ways similar to the . But such networks, the research trio found, are vulnerable to infiltration by foreign code.

The effect of high intensity interval training on telomere length and telomerase activity in non-athlete young men

Posted by in categories: biotech/medical, life extension

Exercise: Good for your mind, body, and telomeres!


Introduction: Telomeres are DNA portions that are located on the two ends of the chromosome. Telomeres play an important role in cellular life. Exercise is one of the factors that contributes to their control. The purpose of the present study was to investigate the effect of 8 weeks of high intensity interval training (HIIT) on telomere length and telomerase activity in non-athletic young men. Materials and methods: 30 inactive students were selected as sample and randomly divided into two groups of exercise (15 people) and control (15 people) in this semi-experimental study. The exercise group performed 8 weeks of HIIT exercise in 3 sessions per week with an intensity of 150 to 175% of their maximum power (Pmax). Control group subjects did not do regular sport activities. To measure telomere length and telomerase activity, 10 ml of blood was taken from the brachial vein of the subjects 24 hours before the first and after the last exercise session. The dependent t was used to analyze intra-group and independent t for within-group differences. Results: The findings of this study showed that 8 weeks of HIIT training in non-athlete young men resulted in a significant increase in telomere length (P = 0.001) and telomerase activity (P = 0.001). Conclusion: It seems that HIIT can alter telomerase activity and telomere length. Therefore, these training may have a positive effect on cell biology.

Nanometer no more: Intel changes its process names to match TSMC

Posted by in categories: futurism, innovation

Intel is matching foundry rival, TSMC, node-for-node with its new process naming convention, but has also fired the first shot in the race for sub-nanometer terminology. Below 1nm, we’re moving into what it’s now calling the ‘angstrom era of semiconductors’.

At the Intel Accelerated event CEO, Pat Gelsinger, has unveiled a detailed process roadmap for its future nodes, all tied into a new way to reference them. “We are accelerating our innovation roadmap to ensure we are on a clear path to process performance leadership by 2025,” he says.

Could China Dethrone The U.S. Dollar With A Digital Yuan?

Posted by in category: cryptocurrencies

The U.S. dollar remains the world’s de facto monetary reserve, but with China going full speed ahead with its digital yuan, that could be in jeopardy. Researchers are digging into regulated online money called Central Bank Digital Currencies, or CBDCs, and what that could look like in the U.S.

Scientists Develop ‘Food Generator’ That Turns Plastic Into Edible Protein

Posted by in categories: bioengineering, chemistry, food

Humanity has a plastic problem, but who said the problem couldn’t also be tasty? Scientists are trying to come up with creative solutions to address the ever-growing issue every day, with some even converting plastic bottles into vanillin using bacteria. Most recently, two scientists have echoed this sentiment and won the $1.18 million (1 million euro) 2021 Future Insight Prize in the process by creating a food ‘generator’ concept that turns plastics into protein.

The names behind the project, which was initially funded by a Defense Advanced Research Projects Agency (DARPA) cooperative agreement award for $7.2 million over four years, are Ting Lu, a professor of bioengineering at the University of Illinois Urbana-Champaign, and Stephen Techtmann, associate professor of biological sciences at Michigan Technological University.

Their goal was to improve a process for converting plastic trash into protein powder and lubricants using a combination of chemicals and high heat (pyrolysis). The two scientists call their project a food ‘generator.’
