Evolutionary history of honeybees revealed by genomics
In a study published in Nature Genetics, researchers from Uppsala University present the first global analysis of genome variation in honeybees. The findings show a surprisingly high level of genetic divers ...
Scientists use genetics, climate reconstructions to track global spread of modern humans out of Africa
(Phys.org)—Research indicates the out-of-Africa spread of humans was dictated by the appearance of favourable climatic windows.
Coastal cities face rising risk of flood losses, study says
The world's 136 largest coastal cities could risk combined annual losses of $1 trillion (750 billion euros) from floods by 2050 unless they drastically raise their defences, a study warned Sunday.

Climate change was not to blame for the collapse of the Bronze Age
Scientists will have to find alternative explanations for a huge population collapse in Europe at the end of the Bronze Age as researchers prove definitively that climate change - commonly assumed to be responsible - could ...
'Big data' takes root in the world of plant research
Botanists at Trinity College Dublin have launched a database with information that documents significant 'life events' for nearly 600 plant species across the globe. They clubbed together with like-minded ...
New research findings consistent with theory of impact event 12,900 years ago
(Phys.org)—New research findings published in the Proceedings of the National Academy of Sciences (PNAS) are consistent with a controversial theory that an extraterrestrial body – such as a comet – i ...
Scientists map unprecedented urbanization in East-Southeast Asia
Researchers have, for the first time, mapped the rapid urban expansion that has occurred across the whole of East-Southeast Asia in the last decade.
Study shows how sea otters can reduce CO2 in the atmosphere
(Phys.org)—Can an abundance of sea otters help reverse a principal cause of global warming?
Fossils link Caribbean bat extinction to humans, not climate change
Sharing caves with millions of bats, the Caribbean's first humans may have driven some species of the winged mammals to extinction.
Climate change causes high, but predictable, extinction risks
Judging the effects of climate change on extinction may be easier than previously thought, according to a paper published today in the journal Nature Climate Change.
Water 'thermostat' could help engineer drought-resistant crops
Duke University researchers have identified a gene that could help scientists engineer drought-resistant crops. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability ...
Population stability 'hope' in species' response to climate change
Stable population trends are a prerequisite for species' range expansion, according to new research led by scientists at the University of York.
Spread of crop pests threatens global food security as Earth warms
A new study has revealed that global warming is resulting in the spread of crop pests towards the North and South Poles at a rate of nearly 3 km a year. The study, published in the journal Nature Climate Change and carrie ...
