Three-Parent Conception Helps Reduce Risk Of Inherited Mitochondrial Disease
2014-06-03 12:53:49

Brett Smith for redOrbit.com - Your Universe Online To prevent deadly, inherited mitochondrial diseases – UK doctors have devised a unique scheme: create a fertilized embryo using eggs from two different women and sperm from one man. According to a new report from the country’s Human Fertilization and Embryology Authority (HFEA), the proposed procedure would be safe and possibly useful, setting the stage for a debate surrounding the ethics of engineering a three-parent child. The US...

This week in Molecular Biology and Evolution Male bears are seemingly always on the prowl, roaming much greater distances than females, particularly for mating. For bear evolution, studying the paternally inherited Y chromosome is therefore a rich source to trace both the geographic dispersal and genetic differences between bear species. This new study is particularly important, because a large part of our current knowledge about range-wide population structuring in mammals relies on...

Do Mitochondrial Genes Matter?
2014-01-14 11:45:32

Uppsala University Contrary to common belief, mitochondrial genes seem to matter for how well individuals survive and reproduce. These new results are reported by researchers at Uppsala University, Sweden, who studied the genes of a common beetle species. Mitochondria are vital power plants of cells. They carry their own genes, which are inherited only through females, and these genes vary greatly between individuals. In the latest issue of the prestigious scientific journal Ecology...

Getting sleep and regularly exercising may help keep people young at heart. However, new research suggests mutated genes passed down from mothers may also predetermine aging rates. Park Ridge, IL (PRWEB) October 22, 2013 Getting sleep and regularly exercising may help keep people young at heart. However, new research suggests mutated genes passed down from mothers may also predetermine aging rates. The researchers of Karolinska Institute in Sweden and the Max Planck Institute of Biology...

SENS Research Foundation is a non-profit organization based in Mountain View, California, and its primary functions are scientific research and public relations in rejuvenation. (PRWEB) October 18, 2013 The SENS Foundation is looking for ways to modify the mitochondrial genome, which could eliminate mitochondrial mutations. A current avenue of research involves creating 13 of the 37 mitochondrial genes that deal with respiratory function. These engineered genes contain a type of protein...

Mummified Head Not King Henry IV's
2013-10-10 12:06:27

Lee Rannals for redOrbit.com - Your Universe Online A mummified head purportedly belonging to French king Henry IV recently surfaced on the collectors' market in France, but a report from forensic experts has shown that the relic is not royalty at all. Spanish and French researchers claimed to have found positive DNA matches for the mummified head of king Henry IV, as well as a handkerchief that allegedly belong to King Louis XVI. Several historians expressed doubt about the findings,...

Audubon's Warbler May Have 'Borrowed' DNA To Fuel Migration
2013-09-20 09:22:43

University of British Columbia A common songbird may have acquired genes from fellow migrating birds in order to travel greater distances, according to a University of British Columbia study published this week in the journal Evolution. While most birds either migrate or remain resident in one region, the Audubon's warbler, with habitat ranging from the Pacific Northwest to Mexico, exhibits different behaviours in different locations. The northern populations breed and migrate south for...

Our Aging Process Is Hastened Due To Maternal Genetics
2013-08-22 08:28:26

April Flowers for redOrbit.com - Your Universe Online There are many reasons our bodies age. The process is determined by an accumulation of various kinds of cell damage that impair the function of bodily organs. A new study from the Karolinska Institutet and the Max Planck Institute for Biology of Aging shows the damage occurring in the cell’s power plant – the mitochondrion – is of particular importance in the aging process and is determined by the genes we inherit from our...

Lineage Of American Dogs Has Pre-Columbian Roots
2013-07-11 13:33:10

Brett Smith for redOrbit.com - Your Universe Online With all the interbreeding that has gone on over the years amongst dogs from around the world, tracing dog lineages can be very difficult. However, a new study from an international team of scientists has traced canine DNA lineages for uniquely American dogs, like Malamutes and Chihuahuas, back to East Asia -- supporting the theory that humans brought these breeds over the Alaskan Land Bridge that connected the two continents thousands...
