HIV Virus infection: Real Video! (not animation) - WWW.OLOSCIENCE.COM By oloscience Scientists have made a breakthrough in understanding how HIV spreads through the human body after filming the process for the first time ever. Researchers found that the virus is transferred from infected cells to healthy ones in a previously unknown way. It is hoped that the discovery will help researchers create a vaccine to combat the virus, which has led to the deaths of more than 25 million people. The study was made possible after experts created a molecular clone of infectious HIV and inserted a protein into its genetic code which glows green when exposed to blue light. This allowed scientists to see the cells on digital video, and capture the way HIV-infected T-cells interact with uninfected ones. They noted that when an infected cell came into contact with a healthy one, a bridge was created between them, called a virological synapse. Researchers were then able to observe the fluorescent green viral particles moving towards the synapse and into the healthy cell. The US study has broken new ground by revealing that it is the synapse through which the viral proteins are gathered and moved into uninfected cells. The team, comprising scientists from UC Davis university in California, and Mount Sinai School of Medicine in New York, believe that this knowledge could help create new treatments for HIV and Aids. Study author Dr Thomas Huser, chief scientist at the UC Davis Center for Biophotonics Science and Technology, said: "Our findings may explain why attempts to develop an HIV vaccine have so far been unsuccessful. "The more we know about this mode of transfer, the better chance we have of figuring out how to block it and the spread of HIV and Aids." For decades it was believed that HIV was mostly spread around the body through freely circulating particles, which attach themselves to a cell, take over its replication machinery and make multiple copies of themselves. In 2004, scientists discovered that cell-to-cell transfer of HIV also occurred via virological synapses, but it was not understood why the process was so effective in spreading the virus. Due to this, previous efforts to create an HIV vaccine have focused on priming the immune system to recognise and attack proteins of free-circulating virus. The new video footage indicates that HIV avoids recognition by being directly transferred between cells. Dr Huser said: "We should be developing vaccines that help the immune system recognise proteins involved in virological synapse formation and antiviral drugs that target the factors required for synapse formation." Co-author Benjamin Chen, assistant professor of medicine and infectious diseases at the Mount Sinai School of Medicine, added: "Direct T-cell-to-T-cell transfer through a virological synapse is a highly efficient avenue of HIV infection, and it could be the predominant mode of dissemination." Further research intends to discover what happens to viral particles once they are transferred into a newly infected cell. The study's finding are published in the journal Science.

National Geographic explains the biology of homosexuality By dianegosh NatGeo explains how one's sexual orientation is determined during embryonic development. They look at how it is possible for one identical twin to be gay and the other to be straight. They address a new branch of Genetics called, Epigenetics. This area of Genetics explores and explains how one's DNA sequence is NOT the only factor in one's phenotypic (actual) outcome. This episode explains how both twins could have the gene for a disorder, yet only one twin actually has the disorder. The same science explains sexual orientation differences in twins. I have only included the homosexuality explanations.

BioVisions - The Inner Life of the Cell By kovahk Edit: People have been having trouble with the download. Try right-clicking and saving opposed to going to the link. Download the music here: http://mustafaresulcetinel.com/videos... Thanks to mresult for providing the download link. I did not make this video. The Inner Life of a Cell, an three-minute animation created in NewTek LightWave 3D and Adobe After Effects for Harvard biology students, wont draw the kind of box office crowds that more ferocious˜and furrier˜digital creations did last Christmas. But it will share a place along side them in SIGGRAPH's Electronic Theatre show, which will run for three days during the 33rd annual exhibition and conference in Boston next month. Created by XVIVO, a scientific animation company near Hartford, CT, the animation illustrates unseen molecular mechanisms and the ones they trigger, specifically how white blood cells sense and respond to their surroundings and external stimuli.

Drosophila Larva Muscle GFP By christabone This is a video of a Drosophila larva expressing G-CaMP, a flourescent calcium indicator, in muscle tissue. When the muscles experience an influx of calcium and contract, the G-CaMP emits a strong green color under flourescent light. You can see a wave of movement from the posterior to anterior of the larva during the clip.

Protein Synthesis, Translation (3) By neurocirujo Protein Synthesis, Translation Translation - the process of converting the mRNA codon sequences into an amino acid polypeptide chain. 1. Initiation - A ribosome attatches to the mRNA and starts to code at the FMet codon (usualy AUG, sometimes GUG or UUG). 2. Elongation - tRNA brings the corresponding amino acid to each codon as the ribosome moves down the mRNA strand. 3. Termination - Reading of the final mRNA codon (aka the STOP codon), which ends the sythesis of the peptide chain and releases it.

Discovery reveals earthworms more diverse than first thought By bbsrcmedia Scientists have found that the UKs common or garden earthworms are far more diverse than previously thought, a discovery with important consequences for agriculture. BBSRC-funded scientists at Cardiff University have found that many of the common earthworm species found in gardens and on agricultural land are actually made up of a number of distinct species that may have different roles in food chains and soil structure and ecology. This discovery was made when efforts to develop better tools to identify earthworm DNA in the guts of slug and worm-eating beetles produced some very unexpected results.
