While it is clear that they derive from genetic programs already present in fish, their precise origin remains a matter of debate. An international team led by the University of Geneva (UNIGE) with EPFL, the Collège de France, and the universities of Harvard and Chicago has come up with an unexpected answer: Digits may have evolved from the reuse of an ancient region of the genome, initially active in the formation of the fish cloaca rather than their fins. /news/2025-09-fish-cloaca-fingers-scientists-digits.html Evolution Molecular & Computational biology Wed, 17 Sep 2025 14:12:04 EDT news677337122 Tiny tweaks in DNA folding can have big effects.

A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which enables the expression of various genes to "lock in" throughout a cell's lifetime. Failure of this memory can lead to diseases, such as cancer. /news/2025-09-cell-memory-dimmer-dial-onoff.html Cell & Microbiology Molecular & Computational biology Tue, 09 Sep 2025 15:30:27 EDT news676650622 Autophagy—meaning "self-eating" in Greek—is a fundamental cellular mechanism that preserves cell health by recycling and degrading worn-out or dysfunctional components. Serving as an essential housekeeping process, autophagy also plays a key role in strengthening immunity, mobilizing when cells encounter stressors such as starvation or infection to eliminate bacteria, viruses, and other threats. /news/2025-09-uncovering-cells-picky-eaters-team.html Cell & Microbiology Molecular & Computational biology Thu, 04 Sep 2025 17:07:04 EDT news676224421 When scientists discovered how bacteria protect themselves against viral invaders, called phages, in the early 2000s, little did they know they'd stumbled upon a revolutionary tool researchers could use to edit the DNA of living cells. /news/2025-09-crispr-reveals-role-cas9-guardian.html Cell & Microbiology Biotechnology Thu, 04 Sep 2025 04:16:40 EDT news676178180 With the power to rewrite the genetic code underlying countless diseases, CRISPR holds immense promise to revolutionize medicine.
