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.
Cane toad pioneers speed up invasions
Genetic engineers create smarter toxins to help crops fight resistant pests
One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat ...
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 ...
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?
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 ...
Study: Violence, infectious disease and climate change contributed to Indus civilization collapse
A new study on the human skeletal remains from the ancient Indus city of Harappa provides evidence that inter-personal violence and infectious diseases played a role in the demise of the Indus, or Harappan Civilization around ...
Extinct Elephant Seal population reveals an evolutionary 'time-machine'
(Phys.org) —Genetic diversity within isolated populations can occur quite rapidly in evolutionary terms, according to findings of a paper published in Proceedings of the Royal Society B.
Some plants in arid regions benefit from climate change, study finds
(Phys.org)—Dryland ecosystems cover 41% of the Earth's land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive ...
