Researchers take new approach to determine historical population fluctuations
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
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 ...
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 ...
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 ...
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 ...
Meat eating led to earlier weaning, helped humans spread across globe
When early humans became carnivores, their higher-quality diet allowed mothers to wean babies earlier and have more children, with potentially profound effects on population dynamics and the course of human evolution, according ...
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.
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.
Face-to-face: Skull study shows variation of pre-Columbian cultures in Mexico
(Phys.org) —A new analysis of the skulls of prehistoric peoples in Mexico reveals significant regional variation in the facial characteristics of indigenous populations – indicating that there were notable ...
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.
