Virginia Tech Virginia Tech researchers discover which genetic changes pass the test of extremely different ecologies Scientists have long puzzled over the genetic differences between fruit flies that live hardly a puddle jump apart in a natural environment known as "Evolution Canyon" in Mount Carmel, Israel. Now, an international team of researchers led by scientists with the Virginia Bioinformatics Institute at Virginia Tech has peered into the DNA of these closely related flies...

UC Riverside-led research could help identify new anti-malaria strategies A research team led by a cell biologist at the University of California, Riverside has generated a 3D model of the human malaria parasite genome at three different stages in the parasite's life cycle — the first time such 3D architecture has been generated during the progression of the life cycle of a parasite. The parasite that causes malaria in humans is Plasmodium falciparum. The female Anopheles mosquito...

Functional Designer Chromosome In Yeast Could Lead To Better Biofuels And Medicines

Lee Rannals for redOrbit.com - Your Universe Online An international team of researchers have taken an important step in the field of synthetic biology, bringing scientists closer to manufacturing microorganisms that could produce biofuels or even medicines. Scientists reported in the journal Science this week that they have synthesized the first functional chromosome in yeast using a computer-aided system. “Our research moves the needle in synthetic biology from theory to...

Technique Accelerates Gene Discovery

redOrbit Staff & Wire Reports - Your Universe Online Researchers working to decipher the role of genes since the completion of the Human Genome Project may see their efforts accelerated by a new approach that lets them permanently and selectively delete genes from a cell's DNA. The new system, known as CRISPR, was developed by researchers at MIT, the Broad Institute, and the Whitehead Institute, and should allow scientists to study the entire genome at once. In two new papers...

Edited RNA Plus Invasive DNA Add Individuality
2013-11-08 08:19:46

Brown University A study in Nature Communications finds that an enzyme that edits RNA may loosen the genome’s control over invasive snippets of DNA that affect how genes are expressed. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span. The story of why we are all so different goes well beyond the endless mixing and matching of DNA through breeding. A new study in the journal Nature Communications, for...

Stem Cells Reveal Differences Humans Apes

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists from the Salk Institute for Biological Studies have taken stem cells from chimpanzees and bonobos and turned them into induced pluripotent stem cells (iPSCs), and their work has helped to highlight some of the differences between humans and non-human primates. This type of cell, which has the ability to form any other type of cell or tissue in the body, can be used to model diseases that would...

UC Riverside geneticists show the COPIA-R7 transposon enhances the immunity of its host against a pathogenic microorganism Transposons are DNA elements that can multiply and change their location within an organism's genome. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk DNA." Also referred to as transposable elements and jumping genes, they are snippets of "selfish DNA" that spread in their host genomes serving no other biological purpose but...

Radically different viruses share genes and are likely to share ancestry, according to research published in BioMed Central's open access journal Virology Journal this week. The comprehensive phylogenomic analysis compares giant viruses that infect amoeba with tiny viruses known as virophages and to several groups of transposable elements. The complex network of evolutionary relationships the authors describe suggests that viruses evolved from non-viral mobile genetic elements and vice versa,...

  • A stinking tobacco.
  • Offal; waste animal product; organic matter unfit for consumption.
This word comes from the Spanish 'mondongo,' tripe, entrails.
