Personal Genetic Data Exposed To Security Vulnerabilities
2013-01-18 03:39:51

redOrbit Staff & Wire Reports - Your Universe Online Armed with nothing but a laptop and an Internet connection, researchers from the Whitehead Institute for Biomedical Research at MIT say they were able to uncover the identities of almost 50 people who donated DNA to genetic research studies. Their work raises series questions about the privacy practices used to safeguard personal data for volunteers in genomic research. The results of their so-called “vulnerability...

Study Finds Genetic Trail Linking Early Australian Inhabitants With Indians
2013-01-15 10:26:29

Brett Smith for redOrbit.com - Your Universe Online A new study in the early online edition of the journal Proceedings of the National Academy of Sciences (PNAS) from geneticists at the Max Planck Institute in Leipzig, Germany could lead to a rewriting of the cultural history of Australia. The researchers say that a recent genetic analysis shows evidence of a substantial flow of genes running between the Indian and Australian populations about 4,000 years ago. "Interestingly, this...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Physicists and biologists apply Big Data statistical tools to study marine plant evolution A new method that could give a deeper insight into evolutional biology by tracing directionality in gene migration has just appeared in EPJ Data Science. Paolo Masucci from the Centre for Advanced Spatial Analysis, at University College of London, UK, and colleagues identified the segregation of genes that a marine plant underwent during its evolution. They found that the exchange of genes, or gene...

National Geographic Reveals Next Phase Of Its Genographic Project
2012-12-05 16:58:17

[Watch NatGeo Video: Geno 2.0: The Greatest Journey Ever Told] Lee Rannals for redOrbit.com — Your Universe Online National Geographic unveiled the next phase of its Genographic Project, which aims to use DNA to map the history of human migration. The goal for the Genographic Project is to shine new light on humanity's past, offering up clues about humankind's journey across the planet over the past 60,000 years. "Our first phase drew participation from more than...

Native Americans, Northern Europeans Genetically Related
2012-12-01 11:17:42

April Flowers for redOrbit.com — Your Universe Online Northern European populations - including British, Scandinavians, French and some Eastern Europeans - descend from a mixture of two very different ancestral populations a new study finds, and one of these populations is related to Native Americans. The results of this study, published in the November issue of the Genetics Society of America's journal GENETICS, help fill in the gaps in scientific understanding of both Native...

Gene Mutations Begin Showing Up In Last 5,000 Years Of Human Evolution
2012-11-29 10:51:10

Lawrence LeBlond for redOrbit.com - Your Universe Online In a world that´s more than 4 billion years old, humans have only existed for a fraction of that–roughly 200,000 years. In those 200,000 years of existence, not a lot is known about genetic mutation until we close in on the last 5 to 10 thousand years. It is within that time that researchers believe nearly 75 percent of gene mutations have occurred, making our DNA distinctly different now than it was way back when. This...

Researchers Find Bornean Elephants Have Low Genetic Variability
2012-11-23 12:53:02

Lee Rannals for redOrbit.com — Your Universe Online A research lab has identified the genetic markers for an endangered species of elephant, showing the animals have very low genetic variability. The study, published in the journal PLoS ONE, opens up new avenues for the conservation of other endangered species. Researchers took advantage of DNA sequencing methodology in order to try and change the odds when looking for diversity. The Bornean elephant is a unique...

Rare Ethiopian Wolves Under Threat
2012-10-27 07:09:25

April Flowers for redOrbit.com - Your Universe Online Ethiopian wolf populations are genetically fragmenting, scientists say. This is cause for concern because the Ethiopian wolf is the world's rarest canine and fewer than 500 of Africa's only wolf species remain in the wild, according to BBC News. A 12-year study of the wolves, published in the journal Animal Conservation, reveals that there is little genetic flow between the small remaining populations in the Ethiopian highlands,...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
