We Need Both Exploratory and Confirmatory

Abstract We often forget how science and engineering function. Ideas come from previous exploration more often than from lightning strokes. Important questions can demand the mo...

On the permanence of stored information in the human brain.

Many people believe that information that is stored in long-term memory is permanent, citing examples of techniques that are alleged to uncover previously forgotten information...

Teaching thinking skills.

A course was developed to teach cognitive skills that apply to learning and intellectual performance independently of subject matter, stressing observation and classification, r...

Appraising qualitative research articles in medicine and medical education

Although qualitative research is gaining recognition in medicine and in medical education, most clinical teachers do not know how to perform a critical appraisal of articles in ...

Neuropathology of synuclein aggregates

Beginning with the isolation of the fragment of alpha-synuclein (alpha-syn) known as the non-Abeta component of amyloid plaques (NAC peptide) from Alzheimer's disease (AD) brain...

A model for the RNA-catalyzed replication of RNA.

A shortened form of the self-splicing ribosomal RNA intervening sequence of Tetrahymena thermophila has enzymatic activity as a poly(cytidylic acid) polymerase [Zaug, A.J. &...
