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.
Cell circuits remember their history: Engineers design new synthetic biology circuits that combine memory and logic
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.
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 ...
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.
234 cattle genomes sequenced in Phase I of 1000 bull genomes project
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 ...
Sexual reproduction only second choice for powdery mildew
Powdery mildew is one of the most dreaded plant diseases: The parasitic fungus afflicts crops such as wheat and barley and is responsible for large harvest shortfalls every year. Beat Keller and Thomas Wicker, ...
Did the universe evolve to make black holes?
(Phys.org) —The maths underpinning Darwin's theory of natural selection could explain how the universe may be 'designed' to make black holes.
Coming soon: Genetically edited fruit?
Recent advances that allow the precise editing of genomes now raise the possibility that fruit and other crops might be genetically improved without the need to introduce foreign genes, according to researchers writing in ...
Darwin's dilemma resolved: Biologists measure evolution's Big Bang
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the "Cambrian explosion" when most modern animal groups appeared between 540 and 520 million years ...
Scientists notch a win in war against antibiotic-resistant bacteria
A team of scientists just won a battle in the war against antibiotic-resistant "superbugs"—and only time will tell if their feat is akin to the bacterial "Battle of Gettysburg" that turns the tide toward ...
Ancient teeth bacteria record disease evolution
DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.
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 ...
