A group of researchers at the University of Utah proposes a new explanation for why vertebrates including humans and rats still hold on to numerous genetic variants that make them susceptible for being infected by foreign pathogens, or triggering autoimmune diseases.
The genetic variants the team focused its effort... |

In addition to being extremely dangerous to humans on their own, many microorganisms also display the ability to mutate extremely fast, so that they can adapt to new, unexpected situations at a moment's notice. The capability was observed as scientists monitored microbes in a new experiment.
The research team,... |

A large-scale international cooperation of 250 scientists from 20 countries has recently determined that a number of specific genetic variations appear to be present in patients suffering from a wide range of mental illnesses. This connects schizophrenia to bipolar disorder, but more is needed on this issue.

In a new scientific research, investigators determined that schizophrenic patients tend to exhibit a much higher rate of de novo mutations than their parents. These are mutations that occur in these patients exclusively, and cannot be traced in their parents too. The frequency of these genetic errors made researchers... |

A group of experts is convinced that it has discovered the key to prediction the onset of cancer early on. They say that their findings could also bring the goal of personalized medicine closer to reality. What the group did is find the order in which genetic aberrations accumulate and lead to cancer. Armed with this... |

In an analysis that encompassed the entire human genome, geneticists were finally able to measure the amount of mutations mothers and fathers pass to their children. In this first-of-its-kind investigation, the team found that up to 60 mutations are passed from one generation to the next. Studying these mutations is ... |

Scientists say that mutations which aid evolution tend to interfere with each other's actions, when the effects they are causing are beneficial to the host organism. This might help explain why the rate of improvement in organisms is usually high early on, only to decrease after some timeIn past studies, experts... |

According to German investigators at the Max Planck Institute for Molecular Genetics (MPIMG), in Berlin, it would appear that deafness can sometimes be caused by a mutated muscle protein, rather than simply by prolonged exposure to loud noises. In a large number of deafness cases, the condition is brought on by genet... |

Each time a new child is born, they carry some of the genetic material from their mother and father, in equal proportions. In addition to this legacy, they also carry between 100 and 200 genetic mutations, which their parents do not have. Some of these mutations are caused by environmental factors, and represent ada... |
