The first wiring diagram of every neuron in an adult brain and the 50 million connections between them has been produced for a fruit fly . This landmark achievement has been conducted by a large international collaboration of scientists , called the FlyWire Consortium , including researchers from the MRC Laboratory of Molecular Biology ( in Cambridge, UK ), Princeton University, the University of Vermont and the University of Cambridge . It is published in a pair of papers in Nature . The diagram of all 139,255 neurons in the adult fly brain is the first of an entire brain for an animal that can walk and see . Previous efforts have completed the whole brain diagrams for much smaller brains , for example, for that of a fruit fly larva, whi...

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

No Bones About It: New Details About Skeletal Cell Aging Revealed

Image
Originally published at cockrell.utexas.edu on April 04, 2025   It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones. Scientists and researchers around the globe are investigating a series of mysteries about what happens to our bones over time . In a new study, a team led by The University of Texas at Austin , in collaboration with Mayo Clinic and Cedars-Sinai Medical Center just made a major break in the case. New research found that osteocytes undergo dramatic structural and functional changes with age that impair their ability to keep our bones strong . Their findings, published in Small and Aging Cell , offer new insights that could pave the way for better treatments for osteoporosis and age-related bone loss.   Aging and stress can induce cellular senescence in osteocytes, resulting in cytoskeletal and mechanical chan...
