Sixty years ago, Harvard scientists David Hubel and Torsten Wiesel famously showed that altering visual input in young cats irreversibly changed the organization of neurons in the visual…
In domains as diverse as mastering video games, controlling robotic limbs, and finetuning ChatGPT, a family of approaches known collectively as “reinforcement learning” (RL) has revolutionized the field…
Lurking in our genomes are thousands of uncharacterized protein-coding genes. Even more genes can be included in this uncharacterized category if we were to exclude general one- or…
After nearly six decades of groundbreaking work in molecular biology, Richard Losick, the Maria Moors Cabot Research Professor of Biology, has published his final research paper in the…
Potassium ion channels are responsible for the rapid, selective flow of potassium (K+) ions through cell membranes, making it possible for spikes of electric activity (action potentials) to…
Giving zebrafish ketamine can stop them from “giving up” during tasks where trying to swim is futile. A new study led by researchers from the Engert Lab and…
The animal body is bilaterally symmetric, and most sense organs (eyes, ears and nose) occur in pairs. These paired sensory organs provide independent measurements of the environment in…
In a new study published in Science Translational Medicine (PDF), the Hensch Lab shares evidence that erratic maternal caregiving during a critical period leads to attention deficits in…
Work spearheaded by post-doctoral fellow Tadasu Nozaki, in the Kleckner laboratory, and recently published in Nature (PDF), uses a powerful new approach to examine pairing of homologous chromosomes…
Imagine a fish with legs, not just fins. A creature that strolls along the ocean floor, hunting for prey with an almost eerie precision. This is the remarkable…
