According to the conclusions of a new scientific investigation, it would appear that powerful DNA sequencing tools can be used to find the genetic mutations that lead to cancer in individual patients, to map the evolution of their conditions over time, and to determine whether therapies are effective or not.
The dis... |

A group of American investigators announces the discovery of the first batch of solid evidences indicating that the process of methylation – and the adjacent gene sequences – have co-evolved in humans and chimpanzees. The species separated from a common ancestor some 6 million years ago.
This is the fi... |

Researchers from the Universities of Cambridge and Edinburgh made a major breakthrough, that could prevent future bird flu epidemics – they created genetically modified chickens that if infected with the avian influenza virus, do not transmit it to other chickens with which they are in contact.This genetic modi... |

British and American researchers found a new clue that explains the way that cancers appear sometimes, without any warning.Most cancers evolve by following certain steps – cells become premalignant, then abnormally large before turning into cancerous cells, and if early detected, treatments can prove effective,... |

We've all been taught in school that genes alone are responsible for our traits, but a new study carried out by Yale University researchers concluded that there is another mechanism that controls traits variations even in genetically identical individuals.Ten years ago, scientists discovered that a striking perc... |

Mitochondrial Eve (mtEve), the mother of all humans, lived about 200,000 years ago according to Rice statisticians' new found method, that could actually be the most complete statistical study of our species' genetic link with our maternal ancestor that was ever made.The research was based on a comparison b... |

In a new series of experiments, researchers determined that if life were structured like a computer, then it would have an incredibly high chance of spontaneously dying. The experts demonstrated that the operating systems (OS) driving modern-day computers are a lot less qualified at ensuring their survival than the g... |

In a trial that could set a questionable precedent, an Italian court reduced the sentence it gave to a convicted killer, after taking into account behavioral genetics. That is to say, the judges kept in mind the fact that the individual had a number of genes that have been associated with violent behavior, and decide... |

As most of you know, unfurling the genetic material enclosed in each of our cells would result in a six-foot-long strand of DNA. However, inside each cell, all this information remains stored within nuclei that are less than three micrometers in diameter, less than the width of a human hair. Finding out precisely how... |

Particular DNA segments can be found in various amounts from one person to another, even if they are in the same line, as in family. These variations play an important part in our evolution. They can hold the key to boosts of the immune system and to developing resistance to certain diseases, but can also make it a l... |

Experts from the Whitehead Institute for Biomedical Research have recently managed to overcome a major obstacle in human embryonic stem cell (ESC) and induced pluripotent stem (iPS) cell research, when they devised a new method of introducing or modifying genes inside them. While this has been relatively easy to do i... |

The human genome carries within it all the necessary information for everything that goes on in the human body, for generating proteins, neurotransmitters, and all sorts of other chemicals. But it is constantly under attack from outside factors, such as UV radiation from sunlight and harmful additives in our daily fo... |

The sea lamprey is one of the weirdest fish in the oceans, and is a direct descendant of animals that lived millions of years ago. This earned it the classification of “living fossil,” because it also looks very strange, as if from a different time. Now, researchers have discovered that there's more ... |

The platypus is by far the strangest mammal, with its bird-like bill and reptile traits. Its genetics seems to be equally strange, as revealed by a new research published in the Nature journal and carried out by Prof Chris Ponting's team at the Medical Research Council Functional Genomics Unit in Oxford, the Eur... |

A new research published in Current Biology comes to confirm the role zoos, farms and private collections could have in saving menaced species: it seems that up to 50% of the captive tigers could be "purebred" members of an endangered subspecies. This finding may boost the number of animals to be involved in breeding... |

In a world of intense migration and immigration, who can tell where his/her roots are? In fact, countries like US, Canada and Australia are mainly made of more or less recent immigrants. This is more than a question of identity. Various human populations display different genetic predispositions to diseases. Our phys... |

The difference between Danny DeVito and Dolph Lundgren is given only by genes. So far, only two of these genes have been known.

The human body functions based on the activity of about 35,000 genes, comprised in 3 billion DNA bases. And even the bacteria needs hundreds of genes to cope with their metabolic functions. But there must be an extreme of functioning genes into an organism at which life is possible. German researchers discovered in 2... |

Corals may be simple little sea creatures that form magnificent reefs in the tropical waters, but scientists were shocked to discover more genes in them than in humans! ...
