Infants and young children have brains with a superpower, of sorts, say Georgetown University Medical Center neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain’s two hemispheres, youngsters use both the right and left hemispheres to do the same task. The finding suggests a possible reason why children appear to recover from neural injury much easier than adults.

The study published Sept. 7, 2020 in PNAS focuses on one task, language, and finds that to understand language (more specifically, processing spoken sentences), children use both hemispheres...

A putative model attempting to depict different levels of genomic organization that may be associated with specific acquired spermatozoal defects. The sperm nucleus is broken down sequentially until the raw DNA. In human spermatozoa it is proposed that up to 15% of histone complexed DNA may remain after spermiogenesis while the remainder is all protamine complexed. For further information see Ward and Coffey (1991).

A dad’s food intake, drugs, exposure to toxic products and even stress can affect the development and health not only of his unborn children, but even of his grandchildren. They have discovered histones may play a crucial role in the process.

In the past, most epigenetics has focused on a process involving DNA and methyl groups that turn up or down the expression of specific ge...
