UC San Diego’s study reveals that meth and PCP impair memory by causing neurons to switch from glutamate to GABA, a process reversible with specific treatments.

Sustained drug abuse can have many long-lasting effects, including memory loss and reduced cognitive functions, which can persist for years. Now, neurobiologists at the University of California San Diego have identified a reversible, shared mechanism in the brain by which drugs of different classes generate cognitive impairments.

Investigating mechanisms of drug-induced cognitive deficits.

Researchers have developed a promising new optical memory technology using rare earth elements and quantum defects to enable denser and more efficient data storage.

This innovative approach utilizes wavelength multiplexing to increase bit density beyond traditional methods like CDs and DVDs, with theoretical models supporting the potential of near-field energy transfer for long-lasting data retention.

Introduction to Optical Memory Evolution.

Can the absence of inhibition lead to auditory hallucinations? This study shows that the impairment of motor-based sensory predictions causes erroneous monitoring of imprecise internal auditory representations, thus causing auditory hallucinations.

Watching for changes in the Mars ’ orbit over time could be a new way to detect passing dark matter.

Dark matter, potentially in the form of primordial black holes, could be revealing its presence through subtle influences on Mars’ orbit. These black holes, theorized remnants from the early universe, might be detectable every decade as they pass through the solar system, offering a new way to study the elusive dark matter.

Understanding dark matter: theories and experiments.

Summary: Researchers have isolated the electrical activity of individual neurons in the vagus nerve responsible for regulating cardiovascular function in humans. By identifying neurons that fire in sync with the heartbeat, scientists can now study how these neurons monitor or control heart activity.

This breakthrough could lead to new insights into how cardiovascular diseases develop and why vagal neuron activity changes in these conditions. The findings offer a foundation for exploring therapeutic targets in heart disease by studying vagus nerve activity in both healthy individuals and those with cardiovascular issues.

Summary: A recent study explored the link between cadmium exposure and cognitive decline, finding that higher cadmium levels may be associated with thinking and memory problems in white people. The study followed 2,172 people over 10 years, with results showing no association overall but revealing a possible link when analyzing Black and white participants separately.

White participants with high cadmium levels were twice as likely to develop cognitive impairment compared to those with lower levels. However, no similar association was found in Black participants, and further research is needed to confirm these findings.

Summary: Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions.

The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients’ lives.

They planned to fly for four years and to get as far as Jupiter and Saturn.

Built by MIT researchers, the Plasma Science Experiment aboard the Voyager 2 spacecraft took measurements for the last 47 years and 15 billion miles, before shutting down on Sept. 26.

The US Navy is moving forward in its efforts to develop the first sixth-generation fighter, while the Air Force has temporarily halted its program due to concerns about high costs and its effectiveness against new threats.

On October 2, the highest-ranking official in the Navy stated that a contract for the next-generation, carrier-based fighter is anticipated to be awarded.
