A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.

The reconstitution of a functional envelope protein from an extinct hominid retrovirus reveals its receptor and an ancient host defense that may have led to the extinction of the virus.

T cell progenitor homing into the thymus requires kindlin-3 to stabilize their adhesion to vascular integrin ligands when blood flow velocities and shear rates increase during development.

A new hominin species found in a South African cave is part of one of the most unusual hominin fossil assemblages on record.

A family of homing genetic elements that look like inteins but work differently is the progenitor of the endonuclease that enables Saccharomyces cerevisiae to change its mating type.

Introducing a hominoid-specific gene into mice induces cortical folding.

A mouse with a defined mutation in an extracellular matrix protein that is expressed in selected neurons sheds light on circuit abnormalities producing transient hyperkinetic movements.

Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

Before returning home, and when using novel routes, dogs align along the north-south axis, presumably to bring the mental map into register with the magnetic compass.

Endogenous laminins are necessary to build a functional acinus via generating NO, activating p53, HOXD10 and other positive players, but tumor cells neither make laminin nor generate NO, unless they are reverted to an organized structure.
