Scientists Gain Insights From Miscanthus Genome Maps
2012-05-16 08:07:00

Two reports were released this year on the genome of Miscanthus grasses, which are used in gardens, burned for energy and converted into liquid fuels. The first, led by the energy crop organization Ceres, appeared in the journal PLoS ONE; the second, from a team led by researchers at the University of Illinois, is in the journal BMC Genomics. The data, materials, methods and genetic markers used in the latter study are available to the public for further research. Scientists knew that...

LSU Research Finds Orangutans Host Ancient Jumping Genes
2012-05-07 14:34:59

LSU´s Mark Batzer, along with research associate Jerilyn Walker and assistant professor Miriam Konkel, have published research determining that modern-day orangutans are host to ancient jumping genes called Alu, which are more than 16 million years old. The study was done in collaboration with the Zoological Society of San Diego and the Institute of Systems Biology in Seattle and is featured in the new open access journal Mobile DNA. These tiny pieces of mobile DNA are able to copy...

Findings provide tools for better understanding of the human genome Chromosomes are strands of DNA that contain the blueprint of all living organisms. Humans have 23 pairs of chromosomes that instruct how genes are regulated during development of the human body. While scientists have developed an understanding of the one-dimensional structure of DNA, until today, little was known about how different parts of DNA are folded next to each other inside the nucleus. Using a powerful DNA...

First-of-its-kind discovery used revolutionary data crunching computer program running on 48 computer processors for 4 weeks to complete 32 billion searches Analyzing massive amounts of data officially became a national priority recently when the White House Office of Science and Technology Policy announced the Big Data Research and Development Initiative. A multi-disciplinary team of University of Missouri researchers rose to the big data challenge when they solved a major biological...

Reuse of key genes is a common theme Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one. But biologists treasure these small fish for what they are revealing about the genetic changes that drive evolution. Now, researchers have sequenced the stickleback genome for the first time, and they have discovered that as fish in different parts of the world adapted to live in fresh water, the same sites in the genome were changed time and...

New work from the HudsonAlpha Institute for Biotechnology, with collaborators at Stanford University and five other groups, has pinpointed evolution in action. By determining genomic sequence from many groups of stickleback fish, the scientists were able to show specific genomic changes leading to the ability of different fish populations to adapt to new environments. "We were pleased with the ability of genomics to show us what molecular changes are important in evolutionary processes,"...

Wearing shoes and genomics are tied together in strategy to eliminate podoconiosis Farmers in the highlands of southern Ethiopia scratch out a subsistence living from the region's volcanic red clay. The soil supports the farms, but fine-grained, volcanic rock particles in the dirt threaten the farmers and their families. Continual exposure of bare feet to the volcanic soil causes 1 in 20 people to develop a painful inflammation of the lower extremities that, over time, leads to foot...

Genome Reveals Humans, Gorillas More Alike Than Previously Thought
2012-03-08 07:53:30

Researchers who have completed the genome sequence of the gorilla have discovered that the species is more genetically similar to humans than they had previously thought. The study, which was led by researchers at the UK's Wellcome Trust Sanger Institute and the Baylor College of Medicine (BCM), looked at DNA from a 30-year-old female western lowland gorilla from the San Diego Zoo named Kamilah, Dave Mosher of National Geographic News reported on Wednesday. They began studying the...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
