One good turn: Birds swap energy-sapping lead role
Migrating birds 'share the pain' of the arduous task of leading a v-formation, so that they can then take turns saving energy by following in another bird's wake, a new study shows.
Study shows nonlinear pattern of migration due to climatic variations
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 ...
Research duo quantify global human migration numbers
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.
Lao skull earliest example of modern human fossil in Southeast Asia
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 ...
Study finds first-ever evidence of climate change of northern China region dating back thousands of years
Using a relatively new scientific dating technique, a Baylor University geologist and a team of international researchers were able to document—for the first time—a drastic climate change 4,200 years ...
Study traces evolutionary origins of migration in New World birds
Every year, millions of birds make the journey from North America to Central and South America for the winter. But the evolutionary origins of this long-distance migration have remained opaque due to the ...
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.
