Daniel Kahneman changed how we think about human nature – the psychologist remembered by a former student
3+ week, 5+ day ago (1034+ words) Daniel Kahneman’s passing at 90 years old has left a major gap in the field of behavioural science and in the wider intellectual community. His scientific contributions, many made in collaboration with cognitive psychologist Amos Tversky, transformed the disciplines of psychology…...
AI Translates Light Microscopy Into Electron-Microscope Detail to Speed
2+ hour, 19+ min ago (534+ words) Mapping the wiring of the brain at nanometer resolution has long demanded a punishing trade-off: electron microscopy can reveal every synaptic cleft and organelle, but imaging even a cubic millimeter of neural tissue this way takes months or years of…...
AI Graph Tool scFormer Uncovers Rare Cell States Hidden in Single-Cell and
5+ hour, 9+ min ago (75+ words) Rare cells punch far above their weight in biology. Populations that make up less than one percent of a tissue can drive tumor progression, immune evasion, drug resistance, and relapse, while others mark the first steps of lineage commitment or…...
New AI Pipeline Turns Tangled 3D Brain Videos into Clear Neuronal Activity
5+ hour, 23+ min ago (529+ words) Neuroscientists can now record electrical storms of activity from tens of thousands of neurons at once, but a stubborn bottleneck has long stood between the raw data and discovery: turning enormous three-dimensional calcium imaging videos into clean, trustworthy lists of…...
Machine Learning Meets X-Rays to Reveal the Hidden Architecture of Pea
5+ hour, 23+ min ago (95+ words) Every seed is a masterpiece of biological engineering, a compact package in which molecular order and cellular design are woven together to protect and nourish a future plant. For scientists trying to understand how crops such as the yellow pea…...
Google's mapped fruit fly brain has played Doom more than 6,000 times and still hasn't beaten it
18+ hour, 14+ min ago (168+ words) Google mapped the complete brain and central nervous system of an adult male fruit fly, reconstructing more than 166,000 individual neurons. Google's fully mapped fruit fly brain is barely a week old, and it's already been put to work doing what…...
MemBrain v2 Brings End-to-End Membrane Analysis to Cryo-Electron Tomography
8+ hour, 13+ min ago (880+ words) Cryо-electron tomography has quietly become one of the most powerful windows into the interior of cells, allowing researchers to peer at the molecular machinery of life in a state close to its native, frozen-hydrated condition....
Protein Assembly, Not Abundance, Explains Why Cells Behave So Differently
9+ hour, 19+ min ago (689+ words) For decades, biologists have treated protein abundance as the closest available proxy for what a cell is actually doing. Measure how much of each protein a cell produces, the reasoning went, and you have a reasonable snapshot of its functional…...
Transfer Learning Reconstructs the Signaling Histories of Single Cells
10+ hour, 51+ min ago (704+ words) Every cell in the body carries a hidden biography. Long before a researcher harvests a tissue and sequences its contents, that cell has been bombarded by hormones, growth factors, cytokines and stress signals, and its current state is the accumulated…...
Confidence shapes how the brain explains success and failure
1+ week, 1+ day ago (1184+ words) Confidence builds a sense of control, and two brain circuits turn that estimate into how much you learn from a win or a loss. When a job application disappears into silence, you have to decide whether the resume was weak…...
