Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
The normal functions of peptides that aggregate in Alzheimer’s, Parkinson’s, and Huntington’s have been largely overlooked by scientists, but some argue that they are critical for understanding the development of disease.
The long noncoding RNA MINCR, implicated in ALS and Alzheimer’s disease as well as several types of cancer, appears to function differently when present at high versus low levels.
Our perception of quantity, separate from counting or estimation of magnitude more generally, is foundational to human cognition, according to some neuroscientists.
A controversial idea from the mid-20th century is attracting renewed attention from researchers developing theories for how cognition arises with or without a brain.
