New archive of ancient human brains challenges misconceptions of soft tissue preservation
Soft tissue preservation in the geological record is relatively rare, and except where deliberate intervention halts the process of decay (like embalming or freezing), the survival of entire organs is particularly unusual. The spontaneous preservatio.....»»

Prolonged brain development of marmosets could serve as model for human evolution
The development of primate brains is shaped by various inputs. However, these inputs differ between independent breeders, such as great apes, and cooperative breeders, such as the common marmoset (Callithrix jacchus) and humans. In these species, gro.....»»
Bones from shipwreck suggest right- or left-handedness could affect how clavicle chemistry changes with age
A new study of human skeletal remains from the wreck of the 16th century English warship "Mary Rose" suggests that whether a person is right- versus left-handed may influence how their clavicle bone chemistry changes as they age. Dr. Sheona Shankland.....»»
Scientists describe how mycobacteria evade the effects of antibiotics
