Researchers of the University of Texas Medical School in Houston have recently announced that they might have found a way to fight off the human immunodeficiency virus for good by altering the part of its genetic code than never mutates. So far the laboratory tests indicate that the technique is effective, although u... |

The photograph featured here presents a one-year old deer born in captivity at the research center park in the Tuscan town of Prato, near Florence, Italy, which has a single horn placed towards the center of its head, similar to the unicorns fabled in popular myths. The photograph was released yesterday by Gilberto T... |

Some two decades ago researcher Richard Lenski of the Michigan State University started growing 12 laboratory populations out of a single Escherichia coli bacterium, which has evolved for over more than 44,000 generations ever since, thus accumulating even more genetic mutations. Although all 12 populations evolved s... |

A new study conducted at DeCODE Genetics in Iceland and at the Queensland Institute of Medical Research, Australia reveals that skin pigmentation and hair color may not have such an important role in getting skin cancer after sitting in the Sun, not as much as a newly found gene that could be used to predict which pe... |

Newts and salamanders may look cute and helpless, but you'd be surprised to know that they produce one of the most powerful toxins for protection in the amphibian world. Still, the common garter snakes (Thamnophis sirtalis) of North America indulge in rough-skinned newts (Taricha granulosa), considered the most ... |

You may think that cyclopes are found only in ancient Greek legends and myths. But the reality can beat the fiction. In 2006, medics at Kasturba Gandhi Hospital for Women and Children in Chennai, India, witnessed the birth of this cyclops child. The cause was not found, but Cyclopamine, a drug believed to be a powerf... |

You drink like a pig and smoke like a sailor? In this case, it is hard to imagine what type of kids you will have (if you will have). Sperm mutations due to exposure to environmental toxins can be transmitted along the generations, as showed by a research presented at American Association for the Advancement of Scien... |

We know that twins are of two types. Some twins come from two different eggs fecundated by two different sperms (this means they can have different genders); they are just ordinary brothers born at the same moment. This are called dizygotic or non-indentical twins and, like any brothers, they share usually 40-60 % of... |

Here is the answer to why men act dumber than women: mutations in genes located on the X sex chromosome that provoke mental retardation. This is the result of a study made by Australian researchers, collaborating with colleagues from Katholieke Universiteit Leuven in Belgium and the Wellcome Trust Sanger Institute i... |

Humans come as boys or girls, but some organisms do not and without being hermaphrodites, they still have sex. In fact, one of the most primitive types of sexual differentiation has just been described by a team from Duke University Medical Center lead by Dr. Joseph Heitman in the journal Nature. The ancestral sex-d... |

Leukemia is one of the main killer cancers in children. In the last 50 years, medical advance has boosted survival rate from 0 % to 90 %, but the aggressive chemotherapy comes with a high price caused by the secondary effects. Still, hope comes with a new research published in the journal Science and made on four-yea... |

Immortality and eternal youth has always been the dream of the humankind. What about a lifespan of 800 years? Yeasts can do it, in their world, if experience a specific mutation. This is the result of a research published in PLoS Genetics by a team at the University of Southern California. They prolonged the lifespan... |

Those little naughty sperms seem to have an increased vulnerability to mutation. The team at the Wellcome Trust Sanger Institute focused on four unstable areas in the DNA where rearrangements cause genetic diseases called genomic disorders, and discovered that some of these mutations were more frequent in sperm than ... |

Man, this wasn't the most handsome American president... This year a research was made on laser scans of a bronze and a plaster copy of two masks of Lincoln's face, belonging to the Chicago History Museum.This revealed a high degree of facial asymmetry: Lincoln's face was much smaller than the right on... |

The first step towards suicidal is depression. Paradoxically, antidepressants can boost a suicide risk in some persons. Now it is believed that two genes linked to chemical signaling in the brain are possible culprits for this. Few years ago researches started to point that the antidepressant drugs rose the suicide r... |

Is your cousin hot? In a Bedouin society, marrying him/her would be just the common thing to do. But we know that inbreeding is a great risk factor for genetic illnesses. The most varied our genes, the healthier we are. A new research checked how inbreeding affects the children's survival rate. The new research ... |

In Scotland they have Nessie, in northern US Big Foot is to be found, in Himalaya you could meet Yeti, while the Latin Americans have the Chupacabra (the Spanish for "Goatsucker"), a type of mythical vampire creature that sucks the blood of the goats and the chickens and a scare-child. This is what Phylis Canion, a h... |

Sperm competition can go really wild, and sometimes, the race for fertilizing an egg goes beyond natural selection. This seems to explain the higher than normal rate of a mutation that stops skull growth and induces joined fingers and toes, as the same mutation also spurs the division rhythm of the cells that form sp... |

This is the Year of the Pig in the Chinese zodiac. Accidentally or not, some bizarre pigs were born in China this year and they are being given special attention. The birth of these pigs is likely to be seen as a particularly good omen. Or a bad one.In January in Quanzhou a two-faced four-eyed piglet was born, in Mar... |

If bonsai proved that the Japanese people can handle the art of "dwarfism", with Onagadori cocks they show how they can deal with gigantism, too. Onagadori ("Honourable Fowl" in Japanese) is a breed of domestic chicken and the cocks can have a tail reaching 10 m! This is an unchallengeable record amongst birds and pe... |

She may not go to the gym, but she has much more muscles than a long-trained body builder. In the end, whippets should be only lean muscle….well, not that much, anyway. Wendy's look differs a lot from the usual long, lean and sleek look of her counterparts. This female dog was born with a genetic impairment whic... |

They are both involved in sex, and a recent research signals another common point: the same killer mutation induces aggressive cancers in these organs. One in six men is hit by prostate cancer and annually 28,000 men die of prostate cancer in the US alone. But a mutation of the gene BRCA2 - previously known to increa... |

You share about 49.99 % of your genes with the guy next door. With her also the same amount. But there may be some mutations you have produced. Or received from them. And usually mutations are rather nasty. 1. Baldness is more common in men, as testosterone sensitive form is the most common. But geneticists still do ... |

Is there any connection between sexual harassment and the flight ability?It seems so...A Chinese woman said her cat has grown wings, reports the Huashang News. Granny Feng remained stunned when she saw how her pet mysteriously grew two 10 cm (4inch)-long wing-like sprouts on its back. "At first, they were just two bu... |

There's no doubt that smoking induces cancer. In the end, cancer is a mutation of the cell's DNA. But tests on mice have shown that smoking-induced mutations have been proved to occur also in the sperm cells and in this case, the mutations can be transmitted to the offspring. "Here we are looking at male ge... |

After getting images of how our memories form, now scientists have discovered how to detect genetic changes (mutations) in the body in standard imaging techniques. The technique could be essential in assessing if a tumor decreases or a drug is active. Researchers likened their device to science fiction movie technolo... |

Viruses are entities at the limit of living and non-living. Unlike bacteria, a virus can not feed and reproduce by itself; instead, it needs a host cell to accomplish these functions. That's why they induce diseases; over 50 % of the human diseases and 90 % of the human infections are virus-provoked. A virus is ... |
