Dragonfly Study Shows How Ecosystem Changes Affect Biodiversity
2013-08-14 07:22:29

April Flowers for redOrbit.com - Your Universe Online Rice University researchers have found that communities in nature are likely to be a lot more sensitive to change than previously thought. The study findings, published in Nature Communications, points to a need for scientists concerned with human impact on the biosphere to take a different look at the consequences of altering the dynamics of a population. One example of such alteration would be removing large members of a species...

Chinese Alligator Genome Sequencing Complete
2013-08-10 05:29:43

April Flowers for redOrbit.com - Your Universe Online Scientists from Zhejiang University in China and  BGI Shenzhen have completed and analyzed the genomic sequence of the endangered Chinese alligator (Alligator sinensis) – the first published crocodilian genome. The findings, published in Cell Research, provide plausible explanations of how terrestrial reptiles adapt to aquatic environments and temperature-dependent sex determination (TSD). The Chinese alligator is critically...

Two women have the same genetic mutation – an abnormal BRCA1 gene that puts them both at much higher-than-average risk for breast cancer – but only one woman develops the disease. Why? Michigan State University genetic scientists have begun to understand the mechanisms behind the phenomena. "It's been known for a while that genetic mutations can modify each other," explained Ian Dworkin, MSU associate professor of zoology. "And we also know that the...

New Clues About Human Ancestry
2013-08-02 05:16:23

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists have been able to trace human ancestry through the male line by sequencing the DNA of multiple entire Y chromosomes - and this so-called "Adam" lived during roughly the same time period as the female most recent common ancestor (MRCA), mitochondrial "Eve," they have discovered. The MRCAs, mitochondrial Eve and Y-chromosomal Adam, are two individuals who passed down a portion of their genomes to the...

Wildlife Conservation Society study finds impending economic growth and climate change impacts require long-term adaptation efforts to conserve Myanmar's unique biodiversity Long isolated by economic and political sanctions, Myanmar returns to the international community amid high expectations and challenges associated with protecting the country's great natural wealth from the impacts of economic growth and climate change. In a new study, scientists from the Wildlife Conservation...

Diverse approaches and techniques may be the key to revealing the complex relationships between plants and wide-scale biological changes Recently, climate change, including global warming, has been a "hot" news item as many regions of the world have experienced increasingly intense weather patterns, such as powerful hurricanes and extended floods or droughts. Often the emphasis is on how such extreme weather impacts humans, from daily heat index warnings to regulating CO2 emissions. While...

Genetic Hitchhikers Picked Up By Evolution
2013-07-23 11:01:42

Princeton University In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride. These hitchhikers are mutations that do not appear to have a role in contributing to an organism's fitness and therefore its evolution, yet may play an important role down the road. Researchers from Princeton University...

Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the "female" counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized role in sperm production. This surprising finding, reported by Whitehead Institute scientists in a paper published online this week in the journal Nature Genetics, is paired with another unexpected outcome: despite its reputation as the...
