We've all been in situations in which the person we were talking to seemed oblivious to the fact that we looked sick and not in the mood, and just kept on ranting for hours on end. The ability to empathize – that is, to figure out what other people are feeling without them saying it, and to relate to their... |

For many years, a large number of scientists have argued that human evolution may have come to a standstill, and even that we may be regressing. These ideas were mostly founded on the lack of observable evidence to support the claim that we were still moving ahead on the evolutionary ladder. More recent data pointed ... |

In a recent set of studies, investigators have finally found one of the most important genes in our bodies, the one that determines our ability to formulate and understand speech. The gene, called FOXP2, can be found in all humans, but lacks in chimpanzees, other primates and big apes. It is a transcription factor, w... |

Over the past decades, deciphering the human genome has been one of the main endeavors of the scientific community. The first genome sequencing was announced in the mid-1990s, and, since then, experts have been working on mapping the locations of all genes involved in any given process inside the body. This is an ext... |

Australian scientists have made an interesting discovery recently, when they have managed to pinpoint the gene that is mostly responsible for a person having curly or straight hair. The TCHH gene (trichohyalin), which is located on chromosome one, appears to be the determining factor, the science team, from the Queen... |

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... |

Figuring out the differences between orangutans, chimpanzees and humans is not a complex process in itself.

Scientists have known for a long time that a causal connection exists between diabetes and obesity, but new drugs and therapies developed in the lab have always focused on treating either one of the two, and not both at the same time. However, as Reuters reports, a new medicine apparently has the ability to make lab ... |

A peculiar human statistic shows that most people who taste the chemical known as PTC find the compound very bitter. Conversely, about 25 percent of the population cannot sense it at all, and therefore has no opinion on it. Science explains this by showing that the two groups of people have different taste receptors ... |
