For mutations, "synonymous" is not a synonym for silent, study finds

June 9, 2022
By Anette Breindl
A central assumption about so-called synonymous mutations, which are changes in the coding sequence of proteins that do not lead to changes in its amino acid sequence, is being questioned by a study published in the June 8, 2022, issue of Nature.

Studies identify chronic pain mechanisms in skin and spinal cord

May 31, 2022
By Anette Breindl
In two separate studies, researchers have identified how peripheral nerve injury can lead to increased pain sensitivity. The studies were published on May 25, 2022, in Nature and May 26, 2022, in Science, respectively. The mechanisms they identify could lead to new therapeutic approaches to chronic pain and/or pain hypersensitivity.
