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 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

Mapping ATP's journey: Key protein identified as gateway for energy delivery into endoplasmic reticulum

Originally published by Stockholm University on May 21, 2025 edited by Sadie Harley , reviewed by Robert Egan   Scientists reveal how ATP is transported into the ER by the protein SLC35B1. Credit: Surabhi Kokane using Biorender. A team of scientists has answered a long-standing question in cell biology , uncovering h ow the cell's main energy currency, ATP , is transported into the endoplasmic reticulum ( ER ) . Disrupted energy transport could affect diseases such as type 2 diabetes, cancer, and neurodegenerative disorders . The study, " Step-wise ATP translocation into the ER by human SLC35B1 " published in Nature , confirms that the transporter protein SLC35B1 is the key gateway for ATP entry into the ER . The research , led by David Drew, professor of biochemistry at Stockholm University and located at SciLifeLab , reveals the first structural and mechanistic insight into how ATP enters the endoplasmic reticulum (ER) using the transporter protein SL...
