Gene expression altered by direction of forces acting on cell
Tissues and cells in the human body are subjected to a constant push and pull—strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by ...

Rodent ancestors combined portions of blood and venom genes to make pheromones
Experts who study animal pheromones have traced the evolutionary origins of genes that allow mice, rats and other rodents to communicate through smell. The discovery is a clear example of how new genes can evolve through ...

Ansell's mole-rats found to use their eyes for south-easterly orienteering
A team of researchers from the University of Duisburg-Essen, Charles University and the Max Planck Research Group Neurobiology of Magnetoreception, has found that Ansell's mole-rats use their eyes to orient their nesting ...
Adaptive genetic markers identify the origins and dispersal of invasive species
The western area of the Iberian Peninsula could be determinant in the origin of the ancestral population of Drosophila subobscura, an invasive species widely spread across multiple latitudes. This is the conclusion of a study ...

Study traces the evolution of gill covers
The emergence of jaws in primitive fish allowed vertebrates to become top predators. What is less appreciated is another evolutionary innovation that may have been just as important for the success of early vertebrates: the ...

Primate brain size does not predict their intelligence
Chimpanzees, gorillas and orangutans are our closest relatives, and like us they have relatively large brains and they are very intelligent. But do animals with larger brains really perform better in cognitive tests? A research ...

The surprising organisation of avian brains
Birds and mammals have the largest brains in relation to their body. Apart from that, however, they have little in common, according to scientific opinion since the 19th century: mammalian brains have a neocortex, i.e. a ...
