The Brain Processes Speech in Parallel With Other Sounds
Scientists thought that the brain’s hearing centers might just process speech along with other sounds. But new work suggests that speech gets some special treatment very early on.
How Animals Map 3D Spaces Surprises Brain Researchers
When animals move through 3D spaces, the neat system of grid cell activity they use for navigating on flat surfaces gets more disorderly. That has implications for some ideas about memory and other processes.
Chemistry Nobel Prize Honors Technique for Building Molecules
Benjamin List and David MacMillan received the 2021 Nobel Prize in Chemistry for their development of asymmetrical organocatalysis.
Medicine Nobel Prize Goes to Temperature and Touch Discoveries
David Julius and Ardem Patapoutian were awarded the 2021 Nobel Prize in Physiology or Medicine for their discoveries of how we detect heat and touch.
To Learn More Quickly, Brain Cells Break Their DNA
New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
The Brain Doesn’t Think the Way You Think It Does
Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging.
Animals Count and Use Zero. How Far Does Their Number Sense Go?
Crows recently demonstrated an understanding of the concept of zero. It’s only the latest evidence of animals’ talents for numerical abstraction — which may still differ from our own grasp of numbers.
Plasmid, Virus or Other? DNA ‘Borgs’ Blur Boundaries.
Scientists have reported large DNA structures in some archaea that defy easy categorization.
DNA Has Four Bases. Some Viruses Swap in a Fifth.
The DNA of some viruses doesn’t use the same four nucleotide bases found in all other life. New work shows how this exception is possible and hints that it could be more common than we think.
