Humans Share Genes With Earlier Human Species
2011-11-01 08:38:39

Humans not only mated with the ancient Neanderthals, but according to a new study from Uppsala University researchers, the East Asian population of the modern species may have also mated with a hominin species known as Denisovans that lived in Siberia 40,000 years ago. Denisovans are only known from a few bone fragments, including a finger bone, a tooth and a possible toe bone, which is still undergoing analysis. Denisovans likely split from the Neanderthal tree around 300,000 years ago,...

Genetic Evidence Confirms Coyote Migration Route To Virginia And Hybridization With Wolves
2011-10-26 03:37:47

Changes in North American ecosystems over the past 150 years have caused coyotes to move from their native habitats in the plains and southwestern deserts of North America to habitats throughout the United States. In a new study, published Oct. 17 in the Journal of Mammalogy, researchers from the Smithsonian Conservation Biology Institute´s Center for Conservation and Evolutionary Genetics used DNA from coyote scat (feces) to trace the route that led some of the animals to colonize in...

Image 1 - Plant Genomes May Help Next Generation Respond To Climate Change
2011-10-07 03:49:35

In the face of climate change, animals have an advantage over plants: They can move. But a new study led by Brown University researchers shows that plants may have some tricks of their own. In a paper published in Science, the research team identifies the genetic signature in the common European plant Arabidopsis thaliana that governs the plant´s fitness – its ability to survive and reproduce – in different climates. The researchers further find that climate in large...

A team at the Complutense University of Madrid (UCM) has studied the marriage strategies of immigrants in order to determine the nature of endogamic (between people of the same nationality) and exogamic partnerships (between people of different nationalities) in Spain. The preliminary results indicate that, unlike Spanish men, Spanish women prefer immigrants with more qualifications. "It caught our attention that human capital was more important in determining outmarriage amongst Spanish...

(Ivanhoe Newswire) -- Type 1 diabetes affects 200 million people worldwide. Now, researchers have discovered new genes that will help them better understand the origin of this complex disorder. In a study published online today in Public Library of Science Genetics (PLoS Genetics), two doctors described their findings. The genes were uncovered during the largest-ever analysis of available genetic data related to type 1 diabetes, a process called meta-analysis. Study leader Hakon...

Meta-analysis Finds New Genes For Type 1 Diabetes

Children's Hospital of Philadelphia researchers add to gene inventory of a complex disorder The largest-ever analysis of genetic data related to type 1 diabetes has uncovered new genes associated with the common metabolic disease, which affects 200 million people worldwide. The findings add to knowledge of gene networks involved in the origin of this complex disorder, in which patients depend on frequent insulin injections to control their blood sugar levels. "Genome-wide association...

In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia. The research, published in the American Journal of Physical Anthropology, is part of a special section which explores who the first Americans were and how they were able to settle in the last great unexplored habitat. The research, by Sohini...

Researchers at the RIKEN Center for Genomic Medicine (CGM), together with colleagues at Kyoto University, Tsukuba University, Harvard University, and other medical institutions have identified three new loci associated with susceptibility to adult asthma in the Japanese population. The findings appear in Nature Genetics and derive from a genome-wide study of 4836 Japanese individuals. Around the world, hundreds of millions of people suffer from bronchial asthma, a chronic inflammatory disease...

New research has found that in urban fox families, the mothers are the ones who decide which cubs stay and which must leave. Red foxes have successfully established themselves in urban areas, living in family groups with a dominant male-female pair and a varying number of subordinate adults, according to the researchers. Some of the cubs remain in the family group for the rest of their lives, while others leave to search for another family to join. Scientists have hypothesized what drives...

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...
