DNA of 'Evolution Canyon' fruit flies reveals drivers of evolutionary change
Scientists have long puzzled over the genetic differences between fruit flies that live hardly a puddle jump apart in a natural environment known as "Evolution Canyon" in Mount Carmel, Israel.
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.
To fight malaria, we now have genetic weapons that can track and kill
Every year malaria kills more than 600,000, which is a little less than the population of Bhutan. There are some simple solutions to control the disease, but keeping the numbers of mosquitoes with malaria ...
Scientists unravel the genetic secrets of nature's master of mimicry
Scientists investigating how one of the greatest shape shifters in the natural world is able to trick predators to avoid being eaten have identified the gene behind the fascinating feat.
More than just a hill of beans: Phaseolus genome lends insights into nitrogen fixation
The US Department of Energy Office of Science has targeted research into the common bean because of its importance in enhancing nitrogen use efficiency for bioenergy crops sustainability, and for increasing ...
Researchers study the genetics and biology of Brassica crop species
Scientists at the University of York have contributed to a new study which represents a significant step forward in understanding the molecular processes which underpin the evolution of genomes in Brassica species.
Delegating the dirty work is a key to evolution
We have hundreds of types of cells in our bodies – everything from red blood cells to hair follicles to neurons. But why can't most of them create offspring for us?
Researchers reverse a liver disorder in mice by correcting a mutated gene
Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.
Fly dreams and the boundaries of evolutionary science
Rapid evolution of novel forms: Environmental change triggers inborn capacity for adaptation
In the classical view of evolution, species experience spontaneous genetic mutations that produce various novel traits—some helpful, some detrimental. Nature then selects for those most beneficial, passing ...
Environment drives genetics in 'Evolution Canyon'
Interplay between genes and the environment has been pondered at least since the phrase "nature versus nurture" was coined in the mid-1800s. But until the arrival of modern genomic sequencing tools, it was hard to measure ...
Evolution of new species requires few genetic changes
Only a few genetic changes are needed to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves ...
Bad news for fake pearls
(Phys.org) —For the first time, a group of researchers has succeeded in isolating DNA from pearls and used their genetic material to identify the specific species of oyster that produced the pearl. In a ...
A foundation for future research: Study tests precision of protein 'machine'
Since its discovery, researchers have hailed Cas9—a protein "machine" that can be programmed by a strand of RNA to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes—as a potential ...
