Long COVID Puzzle Pieces are Falling into Place—the Picture is Unsettling

Posted by in categories: biotech/medical, health, neuroscience

Since 2020, the condition known as long COVID-19 has become a widespread disability affecting the health and quality of life of millions of people across the globe and costing economies billions of dollars in reduced productivity of employees and an overall drop in the work force.

The intense scientific effort that long COVID sparked has resulted in more than 24,000 scientific publications, making it the most researched health condition in any four years of recorded human history.

Long COVID is a term that describes the constellation of long-term health effects caused by infection with the SARS-CoV-2 virus. These range from persistent respiratory symptoms, such as shortness of breath, to debilitating fatigue or brain fog that limits people’s ability to work, and conditions such as heart failure and diabetes, which are known to last a lifetime.

Can odors help fight infection? Nematode research suggests so

Posted by in categories: biotech/medical, robotics/AI

In a recent study published in Science Advances, researchers from the University of California, Berkeley, used the nematode model Caenorhabditis elegans to determine whether the olfactory nervous system could non-autonomously control the mitochondrial unfolded protein response in response to cellular stress.

A critical part of maintaining a state of cellular homeostasis is coordinating responses to environmental stress across tissues. Substantial evidence now supports the fact that the central nervous system regulates stress across all tissues. Furthermore, cell non-autonomous induction of stress responses occurs in peripheral tissues when unfolded protein responses (UPR) in the mitochondria and the endoplasmic reticulum are activated in the neurons.

Stressed cells undergo misfolding or unfolding of proteins, and UPR transmits protein folding status information to the nucleus to enable cellular stress responses or induce apoptotic cell death. The non-autonomous control of cellular stress responses is believed to be essential for the organism to survive toxic environmental conditions.

Webb Unveils Scorching Storms on Distant Worlds in Unprecedented Detail

Posted by in category: space

Astronomers used the James Webb Space Telescope to create a comprehensive weather report for two brown dwarfs located about six light years from Earth.

Researchers have created the most detailed weather report ever for two distant worlds beyond our own solar system.

The international study – the first of its kind – reveals the extreme atmospheric conditions on the celestial objects, which are swathed in swirling clouds of hot sand amid temperatures of 950°C (1750°F).

Study unveils limits on the extent to which quantum errors can be ‘undone’ in large systems

Posted by in categories: quantum physics, robotics/AI

Quantum computers have the potential of outperforming conventional computers on some practically relevant information processing problems, possibly even in machine learning and optimization. Yet their large-scale deployment is not yet feasible, largely due to their sensitivity to noise, which causes them to make errors.

EastWind Attack Deploys PlugY and GrewApacha Backdoors Using Booby-Trapped LNK Files

Posted by in categories: cybercrime/malcode, government

The Russian government and IT organizations are the target of a new campaign that delivers a number of backdoors and trojans as part of a spear-phishing campaign codenamed EastWind.

The attack chains are characterized by the use of RAR archive attachments containing a Windows shortcut (LNK) file that, upon opening, activates the infection sequence, culminating in the deployment of malware such as GrewApacha, an updated version of the CloudSorcerer backdoor, and a previously undocumented implant dubbed PlugY.

PlugY is “downloaded through the CloudSorcerer backdoor, has an extensive set of commands and supports three different protocols for communicating with the command-and-control server,” Russian cybersecurity company Kaspersky said.
