A Power Law Keeps the Brain’s Perceptions Balanced
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Nobel Awarded for Lithium-Ion Batteries and Portable Power
John Goodenough, M. Stanley Whittingham and Akira Yoshino shared the 2019 Nobel Prize in Chemistry for developing lithium-ion batteries, "the hidden workhorses of the mobile era."
Nobel Prize Awarded for Discoveries on How Cells Adapt to Oxygen
The 2019 Nobel Prize in Physiology or Medicine honored William Kaelin Jr., Peter Ratcliffe and Gregg Semenza for their work on elucidating how cells adjust to low oxygen levels.
Your Brain Chooses What to Let You See
Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.
To Pay Attention, the Brain Uses Filters, Not a Spotlight
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
Origin-of-Life Study Points to Chemical Chimeras, Not RNA
Origin-of-life researchers have usually studied the potential of pure starting materials, but messy mixtures of chemicals may kick-start life more effectively.
Fossil DNA Reveals New Twists in Modern Human Origins
Modern humans and more ancient hominins interbred many times throughout Eurasia and Africa, and the genetic flow went both ways.
For Embryo’s Cells, Size Can Determine Fate
Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.
In Brain’s Electrical Ripples, Markers for Memories Appear
Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.
