Gang warfare is not unique to humans - banded mongooses do it too. Now researchers from the University of Exeter have shed light on the causes of the fights - and found they are most common when females are receptive to breeding and when there is competition over food and territory.

Neanderthal DNA Adds to Human Gene Expression

The last Neanderthal died 40,000 years ago, but much of their genome lives on, in bits and pieces, through modern humans. The impact of Neanderthals' genetic contribution has been uncertain. Researchers now report evidence that Neanderthal DNA sequences still influence how genes are turned on or off in modern humans.

Diamonds That Deliver

Neutrons, simulation analysis of tRNA-nanodiamond combo could transform drug delivery design principles.

First 3-D Structures of Active DNA Created

Scientists have determined the first 3-D structures of intact mammalian genomes from individual cells, showing how the DNA from all the chromosomes intricately folds to fit together inside the cell nuclei.

How Sperm Swim Revealed in Mathematical Formula

Researchers have developed a mathematical formula based on the rhythmic movement of a sperm's head and tail, which significantly reduces the complexities of understanding and predicting how sperm make the difficult journey towards fertilizing an egg.
