Regeneration in distantly related species: common strategies and pathways

All animals capable of regenerating a lost body part, from an organ or a limb to the whole organism, use a common set of genes. This is the striking discovery of a team of researchers from the Center for Complexity and Biosystems of the University of Milan, led by Caterina La Porta. They analyzed the genetic activity in regenerating tissues from widely different species—from hydra to mice. They found that some of the genes active at the beginning of the regeneration process are the same in very different species, including mammals which have lost this function during evolution, except for the restoration of the liver. The discovery of this shared genetic signature is of great importance to understand how regeneration evolved and could be useful for future regeneration therapies.

A state Supreme Court justice’s open letter to AI

Let me start with two brief stories about social change. The first concerns changing laws and values about relationships. Only in 1967-in the aptly named case of Loving v. Virginia-did the United States Supreme Court recognize that laws prohibiting interracial marriage violated the United States Constitution. Nineteen years before, in 1948, the Supreme Court of…

A First: Israeli Scientists "Have Used the Human Mind to Control Nano Robots Inside a Living Creature"

Researchers at Bar Ilan University and the Interdisciplinary Center in Herzliya, both in Israel, have developed new technology that allows tiny bots to release drugs into the body controlled by human thought alone. The test involved a man using his…
