Brain Area Associated With Impulse Control Discovered

Posted by in categories: biotech/medical, neuroscience

Summary: A new study identified the right inferior frontal gyrus (rIFG) as a central regulator in the brain’s inhibitory control circuit.

Using dynamic causal modeling and fMRI on a sample of 250 participants, the study reveals that the rIFG significantly influences the caudate nucleus and thalamus during response inhibition tasks. This research also shows gender differences in brain function: women have distinct neural patterns in the thalamus, and overall, better inhibitory control correlates with stronger neural communication from the thalamus to the rIFG.

These findings provide valuable insights for developing neuromodulation therapies for mental and neurological disorders with inhibitory control deficits.

Road Salts and Environmental Consequences: A Global Perspective

Posted by in categories: engineering, sustainability, transportation

Are humans disrupting the Earth’s salt cycle through deicing roads and other salt activities? This is what a recent study published in Nature Reviews Earth & Environment hopes to address as a team of researchers led by the University of Maryland examine the environmental impact of salting roads as a safety measure from freezing temperatures, resulting in increased levels of salt throughout the environment, including the air, soil, and water, thus disrupting the Earth’s natural salt cycle. While the Earth’s natural salt cycle is a process that occurs over vast periods of geologic time, human activities are increasing this cycle in alarming ways.

Salts being used as deicing agents are common across the United States during the winter, with more than 44 billion pounds of deicing agent used annually. In fact, between 2013–17, road salts accounted for 44 percent of the salt use in the United States, which accounts for 13.9 percent of total dissolved solids that make their way into streams and waterways across the nation.

“This is a slow-moving train wreck,” said Dr. Megan Rippy, who is an assistant professor in civil and environmental engineering at Virginia Tech and a co-author on the study. “It’s playing out so slowly that it’s easy to overlook that our streams, lakes, and drinking water resources are becoming progressively saltier.”

Medical microrobots that can travel inside your body are (still) on their way

Posted by in category: biotech/medical

Microrobots released into the body could bust up clots, deliver cancer drugs, and even guide listless sperm to their target.

The human body is a labyrinth of vessels and tubing, full of barriers that are difficult to break through.

Using Generative AI As An Interactive Rage-Room Chatbot Raises Mental Health Guidance Qualms

Posted by in categories: neuroscience, robotics/AI

In today’s column, I am continuing my ongoing series that has closely been exploring the use of generative AI as a generalized interactive chatbot that imparts mental health guidance.

But serious and sobering qualms exist. There isn’t a pre-check to validate that someone ought to be resorting to generic generative AI for such advisement. There isn’t any ironclad certification of the generative AI for use in this specific capacity. The guardrails of the generative AI might not be sufficient to avoid professing ill-advised guidance. So-called AI hallucinations can arise (as an aside, the parlance “AI hallucination” terminology is something that I demonstrably disfavor as a phraseology, for the reasons stated at the link here, but anyway generally connotes that generative AI can produce specious or fabricated answers). And so on.

All in all, you might declare that we are immersed in the Wild West of AI-based human mental health advisement, which is taking place surreptitiously yet in plain sight, and lacks the traditional kinds of checks and balances that society expects to protectively be instilled.

Dassault’s newest jet is powered by P&W’s 14,000-pound thrust engine

Posted by in categories: business, transportation

The powerful jet engine will help reduce travel times between popular global destinations in an environment-friendly manner.

Dassault Aviation’s newest business jet Falcon 6X has entered service powered by Pratt and Whitney’s (PW) 812D engines offering 14,000 pounds (lbs) of thrust. The engines underwent rigorous testing since their selection five years ago and will now help the first extra wide-body business jet zoom around the world at 0.9 Mach.

Dassault’s newest offering aims to redefine the travel experience by offering unparalleled comforts of space and luxury in a business jet. The extra wide body design of the aircraft is further enhanced by the “uninterrupted lines” feature of the cabin that de-clutters in interiors like never before.

Space telescope spots ‘superflares’ 10,000 times brighter than Sun — Study

Posted by in categories: energy, physics, space

Scientists have developed a model to better understand the physics of the powerful superflares emitted by stars far beyond our solar system.

Solar flares, which are rapid and strong bursts of energy and radiation that originate from the Sun’s surface, are known to be emitted into space by our Sun.

NASA’s Kepler and TESS missions, however, have discovered several stars may produce superflares that are 100–10,000 times brighter than those emitted by our Sun.
