Summary: Researchers uncovered the mechanisms by which oxytocin (OXT) influences learning and memory in animals. Their study utilized pharmacogenetic techniques to activate specific OXT neurons within the brain, assessing the impact on cognitive functions through tasks like the Novel Object Recognition Task (NORT).

The findings reveal that activating OXTergic neurons significantly enhances long-term object recognition memory, with notable activity observed in the brain’s supramammillary nucleus (SuM) and dentate gyrus. This groundbreaking research not only deepens our understanding of oxytocin’s role beyond social bonding but also suggests its potential in developing treatments for dementia.

Researchers based at the Drexel University College of Engineering have devised a new method for performing structural safety inspections using autonomous robots aided by machine learning technology.

The article they published recently in the Elsevier journal Automation in Construction presented the potential for a new multi-scale monitoring system informed by deep-learning algorithms that work to find cracks and other damage to buildings before using LiDAR to produce three-dimensional images for inspectors to aid in their documentation.

The development could potentially work to benefit the enormous task of maintaining the health of structures that are increasingly being reused or restored in cities large and small across the country. Despite the relative age of America’s built environment, roughly two-thirds of today’s existing buildings will be in use in the year 2050, according to Gensler’s predictions.

Janus nanosheets bring unprecedented control to preparation of nanoscrolls.

Researchers from Tokyo Metropolitan University have come up with a new way of rolling atomically thin sheets of atoms into “nanoscrolls.” Their unique approach uses transition metal dichalcogenide sheets with a different composition on either side, realizing a tight roll that gives scrolls down to five nanometers in diameter at the center and micrometers in length. Control over the nanostructure in these scrolls promises new developments in catalysis and photovoltaic devices.

Rhodopsin can kill cancer cells keeping the surrounding cells healthy 😤

Considerable time and funding are required in development of new medicines necessary for otherwise untreatable illnesses. Professor Yuki SUDO of Okayama University seeks an innovative form of treatment using rhodopsin, a protein with light-reactive qualities. By extracting it and artificially inserting it into affected cells, it could treat illness simply by exposure to a specific type of light. He has succeeded in using rhodopsin to eliminate cells from cancer, the first such accomplishment ever achieved in the world. In this episode, we introduce the research toward a “light switch” to cure disease.

Researchers have proposed a new strategy for the shape assembly of robot swarms based on the idea of mean-shift exploration: When a robot is surrounded by neighboring robots and unoccupied locations, it actively gives up its current location by exploring the highest density of nearby unoccupied locations in the desired shape.

The study, titled, “Mean-shift exploration in shape assembly of robot swarms,” has been published in Nature Communications.

This idea is realized by adapting the mean-shift algorithm, an optimization technique widely used in machine learning for locating the maxima of a density function.

SpaceX still needs a launch license from the FAA, though.

TITUSVILLE, Fla. — SpaceX plans to remove from orbit about 100 of its older Starlink satellites because of a design flaw that could cause them to fail.

In a statement Feb. 12, SpaceX said it would perform controlled descents of about 100 “early-version 1” Starlink satellites out of concerns that the spacecraft could fail in orbit and no longer be maneuver.

“These satellites are currently maneuverable and serving users effectively, but the Starlink team identified a common issue in this small population of satellites that could increase the probability of failure in the future,” SpaceX stated. The company did not elaborate on that issue or identify the specific satellites affected.
