Two Mouths For One Worm
2013-11-07 11:58:54

Max-Planck-Gesellschaft A devious evolutionary path between genetics and environment Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....

Butterflies Offer Insights Into Evolution
2013-10-31 16:39:31

Michael Harper for redOrbit.com - Your Universe Online A new study from the University of Chicago finds it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another. After studying butterflies, the researchers found evolution can happen as the result of a process rather than a single event. In fact, in the case of butterflies, the beginning of a new species could begin with something as...

Veil Of Ignorance Is Sometimes Bliss
2013-10-24 08:22:27

Washington University in St. Louis A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals — and even among genes For the Oct. 16 issue of Biology Letters, a special issue commemorating the 50th anniversary of W.D. Hamilton’s famous paper on kin selection, two Washington University in St. Louis biologists contributed an article describing intriguing exceptions to one of his predictions. The basic idea of...

Scientists Misled By Model Plant About Multicellular Growth
2013-10-22 15:37:42

University of Leeds Scientists have misunderstood one of the most fundamental processes in the life of plants because they have been looking at the wrong flower, according to University of Leeds researchers. Arabidopsis thaliana—also known as thale cress or mouse-ear cress—grows abundantly in cracks in pavements all over Europe and Asia, but the small white flower leads a second life as the lab rat of the plant world. It has become the dominant "model plant" in genetics research...

Pragmatic Approach To Saving What Can Be Saved
2013-10-17 10:45:55

Technische Universität Darmstadt How can biodiversity be preserved in a world in which traditional ecosystems are increasingly being displaced by “man-made nature”? Biologists at the TU Darmstadt and ETH Zurich have developed a new concept for conservation measures that incorporates current landscapes formerly considered ecologically “of little value”. Numerous experiences from islands have shown that this concept has a positive effect on biodiversity. Now the authors are...

Rare Gene Mutation Identified That Sheds Light On Protein's Role In Brain Development
2013-10-16 16:43:32

Duke University Medical Center Though worlds apart, four unrelated families have been united in a medical mystery over the source of a rare inherited disorder that results in their children being born with abnormal brain growth and severe functional impairments. An international team of scientists, led by genetic researchers at Duke Medicine, has solved the case by identifying a recessive gene mutation that reduces the abundance of a certain protein that previously had not been known to...

Discovery Should Save Wheat Farmers Millions Of Dollars
2013-10-10 07:18:02

McGill University Epigenetic factors identified as key to preventing loss of wheat caused by rain and high humidity The global wheat industry sometimes loses as much as $1 billion a year because prolonged rainfall and high humidity contribute to grains germinating before they are fully mature. The result is both a lower yield of wheat and grains of inferior quality. This phenomenon, known as pre-harvest sprouting or PHS, has such important economic repercussions for farmers around the...
