Scientists at the US Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have recently managed to decipher the structure and modus operandi of a remarkable class of ring-shaped protein motors. The team used the state-of-the-art protein crystallography beamline at the Advanced Light ... |

Scientists were recently able to determine precisely how bacteria repaired their own RNA. This is the second such mechanism identified in any living thing, with the first having been found some time ago, in the T4 phage, a virus that attacks bacteria. The find was made by a team of scientists from the University of I... |

For a long time, researchers have been fascinated with how complex life was able to evolve in the first place. From the primordial soup, a mix of amino-acids and basic RNA molecules, proteins, and eventually more complex structures developed, over millions and billions of years. Expert Stanley Miller was the first to... |

Experts from Penn State and the University of Connecticut, in the US, and the University of Beijing, in China, have recently discovered the fact that a certain enzyme inside the human immune system is able to detect certain pairs of viral RNA belonging to infecting pathogens. The enzyme, known as protein kinase R (PK... |

Experts at the University of Manchester have made an important breakthrough in studying the origins and evolution of life, when they synthesized the basic elements of ribonucleic acid (RNA), the connecting link between pre-biotic molecules and the deoxyribonucleic acid (DNA). The find is very important because, until... |

The next step in administering antiviral drugs, especially for STDs, could be through the use of biodegradable nanoparticles, able to carry microRNA strands directly to the place of infection and deliver the tiny acid overtime. One day, the innovation, made possible by the efforts of a Yale research team, could resul... |

According to two independent study teams, one focusing its efforts on mice, and the other on humans, a new type of gene, called a microRNA, is partially responsible for the onset and development of progressive hearing loss. This condition is a hearing deficit that affects millions around the world, especially the eld... |

Researchers at the Georgia Institute of Technology (GIT) have developed a novel technique of peering inside living cells, which allows them to visualize single molecules of ribonucleic acid (RNA), with much more ease than existing methods. With the use of the new instrument, experts could gain even more access into t... |

Researchers investigating the field of drug addiction may have just developed a new method of counteracting people's need for these substances. Rather than addressing the symptoms generated by the lack of the drug, or trying to replace it with something less harmful, the team from the University of Buffalo (UB)&... |

Obtaining real molecules in an artificial environment has been a long-time dream for biology engineers, and one that was not short on difficulties that had to be surpassed to achieve it. But now, scientists at the Scripps Research Institute, in La Jolla, California, managed to create such a molecule, a tiny fragment ... |

The area of genetics covering the alternate roles that various genes play in different cells and tissues has received too little attention over the years, partially because this phenomenon seemed exotic in nature and was not believed to be a regular occurrence. But now, MIT scientists found that alternative spicing i... |

New scientific experiments analyzed the way in which hearts are formed in the small zebrafish, the animal model that is most similar to humans, from a genetic perspective. These creatures are virtually transparent, so they can be seen through. Their rapid multiplying rates allow for studies to go very fast and very s... |

What the new vaccine platform basically does is combine the cure for the disease it's meant to treat with small strands of "silencing" RNA, a type of nucleic acid that is used to eliminate the response some proteins give off when foreign bodies are inserted into the cells. This allows for a more precise and even... |

For some reason or another, all of us like to believe that Earth is special - after all, our planet is the only one able to sustain life that we know of. Indeed, Earth is special in its own way, but life would not have been possible without the significant contribution of material coming form space. In fact, a new st... |

We all know that how we look, behave and function is a question of genes. And genes are made of DNA. But now, a team at Princeton's Department of Ecology and Evolutionary Biology, in a research to be published in the journal "Nature", challenges this.They have found an "epigenetic" pathway bypassing DNA, in a ty... |

Besides its deadly or morbid side, breast cancer is disastrous for a woman's sex-appeal. Now one of the most common worldwide breast cancer types, locally advanced breast cancer (LABC), has been linked by a NYU School of Medicine team to a molecular switch in the protein synthesis. LABC represents over 50 % of b... |

From the color of your hair, eyes, and skin, face shape to all your skills and the way you laugh - everything's a combination of genetics, and how the activity of your genes was shaped by the environment. You may have told your lover she has her father's big blue eyes and her mother's soft skin. Well, ... |

Frogs are anything but intelligent; still, a synthetic version of a molecule coming from their eggs could save our big brains from cancer. The molecule called amphinase recognizes the sugary layer on the surface of tumor cell and binds to it before invading the cell and inactivating the RNA inside, killing the tumor.... |

95 % of our genome has been thought to be just junk, or simply a useless desert. Up until now, as some scientists have started to disagree on this idea. One of them is Professor Alexandre Reymond, from the Center for Integrative Genomics, University of Lausanne, Switzerland and the Department of Genetic Medicine, Uni... |

A newly designed type of DNA computer for human cells could one day lead to the development of a technology able to eliminate the diseased cells and separate them from the healthy ones. The technology is based on the process of RNA interference (RNAi) in which small RNA molecules stop a gene from synthesizing its pro... |

They say a mother is more than a father. That is true, as a mother invests more of its biology in the offspring anyway. During egg development (oogenesis), the mother deposits in it large amounts of messenger RNAs (mRNAs) and proteins. These mRNAs take over after the sperm did its job to orchestrate the emergence of ... |
