Researchers use cellphone data to construct population density maps
Reducing population is no environmental 'quick fix', modelling research shows
New multi-scenario modelling of world human population has concluded that even stringent fertility restrictions or a catastrophic mass mortality would not bring about large enough change this century to solve ...
Physicists suggest electrical networks more at risk of cascading failure than thought
Endangered lemurs' complete genomes sequenced, analyzed for conservation efforts
For the first time, the complete genomes of three separate populations of aye-ayes—a type of lemur—have been sequenced and analyzed in an effort to help guide conservation efforts. The results of the ...
Plant geneticists demonstrate new means of boosting maize yields
A team of plant geneticists at Cold Spring Harbor Laboratory (CSHL) has successfully demonstrated what it describes as a "simple hypothesis" for making significant increases in yields for the maize plant.
Study finds new way in which plants control flower production
The timing of flowering in plants is critical. It can have profound effects on flower, fruit, and seed production, and consequently agricultural yields. This process is known to depend on daylight and temperature ...
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 ...
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.
Wolves, bears and lynx 'now plentiful in Europe' (Update)
After nearing extinction in Europe in the early 20th century because of hunting and shrinking habitats, large carnivores like the gray wolf, brown bear, lynx and wolverine are thriving once more.
Genomic data support early contact between Easter Island and Americas
People may have been making their way from Easter Island to the Americas well before the Dutch commander Jakob Roggeveen arrived with his ships in 1722, according to new genomic evidence showing that the ...
Boron tolerance discovery for higher wheat yields
Australian scientists have identified the genes in wheat that control tolerance to a significant yield-limiting soil condition found around the globe – boron toxicity.
Infection in malaria-transmitting mosquito discovered
Researchers have found the first evidence of an intercellular bacterial infection in natural populations of two species of Anopheles mosquitoes, the major vectors of malaria in Africa. The infection, called ...
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.
Love or kill thy neighbor? New study into animal social behavior
A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations.
