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 ...
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
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.
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 ...
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 ...
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 ...
Genetic study shows major impact of climate change on Antarctic fur seals
Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring, has provided unique insights into the effect of climate change on a population of top-predators. Published in Nature this week, the findin ...
Global warming could help bolster turtle population size
(Phys.org) —Scientists studying the sex ratio of sea turtles at one of the world's largest rookeries predict global warming could help bolster population sizes.
Call for alternative identification methods for endangered species
In a time of global climate change and rapidly disappearing habitat critical to the survival of countless endangered species, there is a heightened sense of urgency to confirm the return of animals thought ...
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.
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.
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 ...
