It’s ChatGPT's first "birthday". And it was a very eventful first year for the field of AI.
Researchers have developed supramolecular memristors for RRAM functions, demonstrating rapid resistance switching cycles of over 1000 and and retention time exceeding 500 seconds under ambient conditions with non-volatile storage capabilities. This paves the way for advanced data storage technologies.
According to this study, reduction in the activity of the INPP5D gene in microglia (immune regulating cells in the brain) leads to increased neuroinflammation, potentially contributing to the progression of Alzheimer’s disease, paving the way for targeted treatments.

Longevity drugs for our canine companions are moving closer to reality. They also raise questions about what it might mean to succeed.
For many years, scientists have been puzzled by the behavior of Pacific Northwest fish-eating killer whales, who have been seen harassing and sometimes killing porpoises without eating them.
A study recently published in Marine Mammal Science, co-led by Deborah Giles of Wild Orca and Sarah Teman of the SeaDoc Society, a program of the UC Davis School of Veterinary Medicine, looked at more than 60 years of recorded interactions between Southern Resident killer whales and porpoises in the Salish Sea to better understand why they exhibit this behavior.
New research links menopause to cognitive deficits and brain atrophy, emphasizing the role of estrogen receptor beta in astrocytes. Findings from female mice studies suggest potential treatments targeting ERβ for improving cognition and reversing brain changes in menopause.

This study in serotine bats (Eptesicus serotinus) shows that the penis is used as a ‘copulatory arm’ rather than an intromittent organ, revealing a novel copulatory behaviour in mammals. DOI:https://doi.org/10.1016/j.cub.2023.0
