Bioengineers develop tool for reprogramming genetic code
Biology relies upon the precise activation of specific genes to work properly. If that sequence gets out of whack, or one gene turns on only partially, the outcome can often lead to a disease.
Bison not cattle's top competitor for range forage, ecologists say
If bison lumber through a patch of rangeland, you'll know it, says Utah State University ecologist Dustin Ranglack. A mature bull, after all, often weighs a ton.
Study shows even newly hatched chicks have a left to right number space map (w/ Video)
Did genetic links to modern maladies provide ancient benefits?
Psoriasis, a chronic skin condition, can cause rashes that itch and sting.
Ancient 'genomic parasites' spurred evolution of pregnancy in mammals
An international team of scientists has identified large-scale genetic changes that marked the evolution of pregnancy in mammals.
Blind beetles show extraordinary signs of sight
University of Adelaide researchers have made a surprising discovery in the aquifers beneath the Western Australian desert, which challenges the traditional Darwinian view of evolution.
Cellular memory of stressful situations
Stress is unhealthy. The cells use therefore a variety of mechanisms to deal with stress and avert its immediate threat. However, certain stressful situations leave marks that go beyond the immediate response; ...
Millions of GMO insects could be set loose in Florida Keys (Update)
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
From Tar Sands to Ring of Fire—forewarning changes to Canada's watersheds
The Tar Sands in Alberta, potential development in the Ring of Fire in northern Ontario, declining timber harvest and farming - human activity is transforming Canada's landscape, yet many of the country's aquatic resources ...
Spider electro-combs its sticky nano-filaments
A spider commonly found in garden centres in Britain is giving fresh insights into how to spin incredibly long and strong fibres just a few nanometres thick.
New research shows our seas are in trouble
New research by the University of Sheffield has warned of the increasing risk of extinction to our marine life.
Evolution of marine mammals to water life converges in some genes
When marine mammals such as whales, dolphins, manatees and walruses moved from land to water, a series of physical abilities —– limbs adapted for swimming, less dense bones that make them more buoyant ...
Researchers find social lifestyle also helps mole rats live a long time
Tracking DNA helps scientists trace origins of genetic errors
Scientists have shed light on how naturally occurring mutations can be introduced into our DNA.
