Observing the random diffusion of missing atoms in graphene
Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating ...

New study refutes claims of early humans in India prior to Mount Toba eruption
Gene flow from India to Australia about 4,000 years ago
Long before Europeans settled in Australia humans had migrated from the Indian subcontinent to Australia and mixed with Australian aborigines.

An ancient skull recovered from a cave in the Annamite Mountains in northern Laos is the oldest modern human fossil found in Southeast Asia, researchers report. The discovery pushes back the clock on modern ...
Which way is up? Key protein in epithelial cells plays important roles in how cells sense direction
What do sled dogs and cell clusters have in common? According to research by UC Santa Barbara's Denise Montell, they both travel in groups and need a leader to make sure they all follow in the same direction.
Small birds capitalize on weather patterns during epic migrations
(Phys.org) —In one of the greatest feats of endurance in the biological world, millions of tiny songbirds—many weighing less than an ounce—migrate thousands of miles to Central and South America each ...
Model shows long-distance migration can lower risk of disease transmission, impact
Animals that migrate long distances are often implicated in the spread of infectious diseases, but there is growing evidence that long-distance migration may actually lower the risks of pathogen transmission ...
Paleoanthropologists use models to show humans may have left Africa earlier than thought
Study reveals why timing of bird migration is changing
Researchers at the University of East Anglia have found out why birds are migrating earlier and earlier each year.
Hitchhiking virus confirms saga of ancient human migration
A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.
Songbirds may have 'borrowed' DNA to fuel migration
A common songbird may have acquired genes from fellow migrating birds in order to travel greater distances, according to a University of British Columbia study published this week in the journal Evolution.
How to migrate: Young whoopers stay the course when they follow a wise old bird
Scientists have studied bird migration for centuries, but it remains one of nature's great mysteries. How do birds find their way over long distances between breeding and wintering sites? Is their migration ...
Scientists have found new evidence to show how early humans migrated into Europe
Humans originated in Africa. But what route did they take as they began to disperse around the world 60,000 years ago? A new professor at the University of Huddersfield has played a key role in finding the answer to one ...
