Intramolecular bivalent glues: A promising avenue for protein degradation

Living cells resemble highly organized small towns - in addition to energy production, transportation systems, and construction, cells also require efficient waste disposal.

“Laboratory testicles” could solve male infertility mysteries

The testis is responsible for sperm production and testosterone synthesis. Abnormalities in testis development and function lead to disorders of sex development (DSD) and male infertility. Currently, no in vitro system exists for modeling the testis.
