| How a particular gene makes night vision possible Posted: 09 Aug 2011 03:41 PM PDT Scientists have determined how a particular gene makes night vision possible. The study focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments.  |
| Study builds on plausible scenario for origin of life on Earth Posted: 09 Aug 2011 11:45 AM PDT A relatively simple combination of naturally occurring sugars and amino acids offers a plausible route to the building blocks of life, according to a new article. The study shows how the precursors to RNA could have formed on Earth before any life existed.  |
| New insights into biology of germ cells: Machinery for recombination is part of chromosome structure Posted: 09 Aug 2011 07:42 AM PDT During the development of gametes, such as egg and sperm cells in humans, chromosomes are broken and rearranged at many positions. Using state of the art technology, researchers in Austria have analyzed this process at high resolution. The surprising observations regarding the mechanism of meiosis are now published in a new article.  |
| Community ecology: For marine microbes, it's not who you are, but what you do Posted: 09 Aug 2011 06:21 AM PDT When you're a tiny creature in a vast ocean it pays to hang out with the right crowd, regardless of whether they are related to you or not, a new study into the amazingly diverse world of marine microbes has found. For bacteria at least, it seems that what matters more than your species identity is whether you have specific genes that let you work with other species to form a functioning community.  |
| Curry spice could offer treatment hope for tendinitis Posted: 09 Aug 2011 05:34 AM PDT A derivative of a common culinary spice found in Indian curries could offer a new treatment hope for sufferers of the painful condition tendinitis, researchers have shown. The researchers have shown that curcumin, which also gives the spice turmeric its trademark bright yellow coloring, can be used to suppress biological mechanisms that spark inflammation in tendon diseases.  |
| New insights into the how the powerhouse of the cell works Posted: 09 Aug 2011 05:32 AM PDT Mitochondria are the powerhouse of the cell. They are thought to have evolved more than a billion years ago from primitive bacterium which was engulfed by an early eukaryotic cell resulting in endosymbiotic relationships between the host cell and the newly formed organelle. During evolution the vast majority of the mitochondrial genetic material left the organelle and got integrated into the nucleus of the host cell. Hence, most of the mitochondrial proteins are synthesized outside of the organelle and have to be imported into the various internal mitochondrial compartments.  |
