Research at MDI Biological Laboratory Sheds New Light on Effects of Dietary Restriction
In new research, Aric N. Rogers, Ph.D., who studies the cellular and molecular mechanisms of aging at the MDI Biological Laboratory in Bar Harbor, Maine, has discovered that muscle may be a protected tissue under conditions of dietary restriction, or DR.
Dietary restriction, in which calories are restricted without malnutrition, is one of the most robust anti-aging interventions. When confronted with a scarcity of nutrients, an organism conserves resources by lowering the translation, or production, of proteins, which is one of the most energetically expensive processes in the cell. Proteins serve as the building blocks for tissues and organs and perform vital physiological functions.

There is Always Something New: A COVID-19 Update
Dear MDIBL Community, As if the epidemic by itself and the last Delta virus have not been enough, we now have Omicron. This new variant of the virus was first sequenced in South Africa in November and tends to be more contagious than the Delta variant. This by itself is a cause of concern. Although…

New Research by Aric Rogers, Ph.D., Sheds Light on the Effects of Dietary Restriction on Muscle Tissue
Consider the following scenarios: In the first, a thin young woman who exercises excessively develops athletic amenorrhea, or stops menstruating, rendering her incapable of bearing children. In the second, a sedentary, overweight girl undergoes menarche at a precociously early age. Aric N. Rogers, Ph.D., who studies aging at the MDI Biological Laboratory, believes these scenarios…

Aging in Mice Linked to Misexpression of Class of Genes
Genes lacking a particular structure known as CpG islands tend to go haywire in older cells, a study finds, potentially contributing to key facets of aging. But it’s not yet clear if the relationship is causal.
