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... |

Vehicles can vary from the size of a train to that of a ...bacterium. A team at Emory University has created a novel way of controlling the movement of the bacterium Escherichia coli in a chemical environment, opening the opportunity for new enhanced drug delivery, environmental cleanup and synthetic biology. The res... |

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 ... |
