Seeking Stability in a Relativistic Fluid

Posted by in categories: information science, particle physics, space

A fluid dynamics theory that violates causality would always generate paradoxical instabilities—a result that could guide the search for a theory for relativistic fluids.

The theory of fluid dynamics has been successful in many areas of fundamental and applied sciences, describing fluids from dilute gases, such as air, to liquids, such as water. For most nonrelativistic fluids, the theory takes the form of the celebrated Navier-Stokes equation. However, fundamental problems arise when extending these equations to relativistic fluids. Such extensions typically imply paradoxes—for instance, thermodynamic states of the systems can appear stable or unstable to observers in different frames of reference. These problems hinder the description of the dynamics of important fluid systems, such as neutron-rich matter in neutron star mergers or the quark-gluon plasma produced in heavy-ion collisions.

Popular YouTube Channel Caught Distributing Malicious Tor Browser Installer

Posted by in category: cybercrime/malcode

A popular Chinese-language YouTube channel has emerged as a means to distribute a trojanized version of a Windows installer for the Tor Browser.

Kaspersky dubbed the campaign OnionPoison, with all of the victims located in China. The scale of the attack remains unclear, but the Russian cybersecurity company said it detected victims appearing in its telemetry in March 2022.

The malicious version of the Tor Browser installer is being distributed via a link present in the description of a video that was uploaded to YouTube on January 9, 2022. It has been viewed over 64,500 times to date.

Researchers Report Supply Chain Vulnerability in Packagist PHP Repository

Posted by in category: cybercrime/malcode

Researchers have disclosed details about a now-patched high-severity security flaw in Packagist, a PHP software package repository, that could have been exploited to mount software supply chain attacks.

“This vulnerability allows gaining control of Packagist,” SonarSource researcher Thomas Chauchefoin said in a report shared with The Hacker News. Packagist is used by the PHP package manager Composer to determine and download software dependencies that are included by developers in their projects.

GI Gmail: US Army launches Google Workspace for troops

Posted by in category: military

Up to 250,000 troops will receive the new service, Google officials confirmed in a blog post. The number aligns with the shortage of Microsoft 365 licenses that Army Times previously identified.

Google Workspace is already used by the Air Force Research Laboratory and various other federal entities. The Army Software Factory was also an early adopter; now, they’ll be permanent Google users.

The launch of Workspace for the Army at large follows months of evaluation behind the scenes.

Scientists Show Transmission of Epigenetic Memory Across Multiple Generations

Posted by in categories: biotech/medical, genetics

Changing the epigenetic marks on chromosomes results in altered gene expression in offspring and in grandoffspring, demonstrating ‘transgenerational epigenetic inheritance.’

Without changing the genetic code in the DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Russia is LOSING the War against Ukraine and has RETREATED from the Key Town of LYMAN which it has held since May and was used as a Supply & Transport HUB for the North of Ukraine. In Direct Response one of President Putin’s RIGHT HAND MEN has Urged Russia to Launch LOW YIELD NUCLEAR STRIKES on Ukraine. In this video I provide full details of the latest situation, as well as providing on update on the NORD STREAM Pipelines, European Gas SUPPLY and details of what a Low Yield Nuclear Bomb is. Finally I provide my view on the implications of the current situation for both Russia & the GLOBAL ECONOMY.

New technique enables on-device training using less than a quarter of a megabyte of memory

Posted by in categories: internet, robotics/AI

Microcontrollers, miniature computers that can run simple commands, are the basis for billions of connected devices, from internet-of-things (IoT) devices to sensors in automobiles. But cheap, low-power microcontrollers have extremely limited memory and no operating system, making it challenging to train artificial intelligence models on “edge devices” that work independently from central computing resources.

Training a on an intelligent edge device allows it to adapt to new data and make better predictions. For instance, training a model on a smart keyboard could enable the keyboard to continually learn from the user’s writing. However, the training process requires so much memory that it is typically done using powerful computers at a data center, before the model is deployed on a device. This is more costly and raises privacy issues since user data must be sent to a central server.

To address this problem, researchers at MIT and the MIT-IBM Watson AI Lab have developed a new technique that enables on-device training using less than a quarter of a megabyte of memory. Other training solutions designed for connected devices can use more than 500 megabytes of memory, greatly exceeding the 256-kilobyte capacity of most microcontrollers (there are 1,024 kilobytes in one ).
