Brain’s ‘Background Noise’ May Hold Clues to Persistent Mysteries
By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.
The Year in Biology
While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.
Why Are Plants Green? To Reduce the Noise in Photosynthesis.
Plants ignore the most energy-rich part of sunlight because stability matters more than efficiency, according to a new model of photosynthesis.
‘Noise’ in the Brain Encodes Surprisingly Important Signals
Activity in the visual cortex and other sensory areas is dominated by signals about body movements, down to little tics and twitches. Scientists are now rethinking how they study and conceive of perception.
Where We See Shapes, AI Sees Textures
To researchers’ surprise, deep learning vision algorithms often fail at classifying images because they mostly take cues from textures, not shapes.
