From Lemurs to Lab Mice, Hibernators Reveal Insights into Human Health

Hibernation helps animals survive periods of harsh conditions. Studying this behavior could uncover clues to treating obesity, preserving organs, and more in humans.

As leaves fall off the trees and temperatures grow bitingly cold, many animals prepare to hibernate for the winter. During this period, animals enter a state of torpor wherein they reduce their metabolic activity and lower their body temperature, which helps them conserve energy. Organisms can also enter other kinds of dormancy or adaptations to stressful environments that resemble hibernation. While studying these behaviors can teach scientists more about the unique biology of these animals, it can also inform human health and disease. These include neurodegeneration mechanisms in the brain, ways to potentially treat metabolic conditions like type 2 diabetes and obesity, how to better preserve organs for transplantation, and much more. Grab a blanket and get cozy to learn more about hibernation.

  Originally published by Kanazawa Universit at www.phys.org, on September 5, 2023 Overview of the method for observing actin fibers in living cells using nanoendoscopy-AFM. Credit: STAR Protocols (2023). DOI: 10.1016/j.xpro.2023.102468 Images of nanoscale structures inside living cells are in increasing demand for the insights into cellular structure and function that they can reveal. So far, the tools for capturing such images have been limited, but researchers led by Takeshi Fukuma and Takehiko Ichikawa at Kanazawa University have now devised and reported a full protocol for using atomic force microscopy (AFM) to image inside living cells . The research is published in the journal STAR Protocols . AFM was first developed in the 1980s and uses the changes in the forces between a sample surface and a nanoscale tip attached to a cantilever to identify surfaces and produce images of the topography with nanoscale resolution. The technique has grown increasingly sophistica...

Neuromorphic camera and machine learning aid nanoscopic imaging

Neuromorphic camera and machine learning aid nanoscopic imaging by Indian Institute of Science Transformation of cumulative probability density of ON and OFF processes allows localisation below the limit of classical single particle detection. Credit: Mangalwedhekar et al In a new study, researchers at the Indian Institute of Science (IISc) show how a brain-inspired image sensor can go beyond the diffraction limit of light to detect miniscule objects such as cellular components or nanoparticles invisible to current microscopes. Their novel technique, which combines optical microscopy with a neuromorphic camera and machine learning algorithms, presents a major step forward in pinpointing objects smaller than 50 nanometers in size. The results are published in Nature Nanotechnology. Original article
