Genome sequencing has revealed insights into how current-day residents of the Faroe Islands can trace their ancestry to a North Atlantic founder population and how evolutionary forces have shaped their genomes since.

UC San Diego biologists have uncovered new details about barrier-forming cells that protect and nourish the brain. Their findings focused on senescent cells, which traditionally have been labelled as “zombie” cells, and their formative role in the developing brain and beyond.

A comprehensive multi-cancer study from researchers at The University of Texas MD Anderson Cancer Center has revealed that cancer cells within tumors are genetically diverse, yet all carry the same core genetic changes that can be traced back to a common ancestral cell, providing a single-cell view of how tumors adapt, survive and diversify. Understanding this helps explain why some cancer cells manage to survive treatments, paving the way for more tailored diagnostic and therapeutic strategies.

Bumblebees see the world differently under stress, processing visual information more sharply and making quicker decisions, new research from Newcastle University, UK, reveals.

Female chickadees living in monogamous mating systems will proactively seek out males that have better cognitive skills than their nestmate.
