According to a recent scientific investigation, it would appear that mountaintop mining exploitations, which basically blow the top off mountains in search for precious chemicals, cause tremendous damage on the environment. In addition, they also pose considerable health risks to the populations living in their immed... |

Evolutionary biologists have for a long time wondered how is it that nature allows for the development of social insects, such as termites and ants. Mega-colonies can have up to millions of members that do not mate, reproduce, or start new colonies, the soldiers and common workers. Given that nature usually selects f... |

A recent discovery showed that fungal species registered speeds of 88 km/h (55 miles per hour), exhibiting accelerations 180.000 times Earth's gravity as they project their spores outwards. The common pathogens of the crops are mostly harmless to humans, but some can still increase the negative effects of a... |

Even in these modern days, when the lifespan of humans surpasses an all time record, women over 40 are generally believed too old to have babies, yet somehow there is no mention of the limit age men become less fertile at. If 40 looked like a rather young age to stop having children, a new study now shows that men ol... |

Sexual reproduction may be a lot of fun, but it's far from being perfect when it comes to combining the genetic material of the parents, sometimes leading to incurable genetic diseases. However, genetically engineered children could literally be born perfect in a couple of years in the UK, by replacing defective... |

Scientists have recently found the oldest known fossil that indicates that reproduction through birth was encountered in vertebrate animals as early as 380 million years ago. The fossil belongs to an armored fish female that was about to give birth, but it perished and got fossilized along with the embryo inside it. ... |

Hugh Hefner or Michael Douglas are just faithful followers of an evolutionary pathway. A new statistical research published in "Biology Letters" reveals that monogamous men indeed have more children if their wives are younger than them, more exactly, by 4 to 6 years.The research team used the data from a Swedish rese... |

1.Scientists believe that kangaroos' and wallabies' ancestors could have looked like a Wynyardia, a 21 million years old marsupial found in Tasmania. The largest living kangaroo, the red kangaroo (Macropus rufus) is also the largest living marsupial. Males are up to 1.8m (6 ft) tall and weigh up to 84 kg (1... |

Sharks have many issues of their own in the reproductive domain, from double penis in case of males to intrauterine cannibalism. Now, another odd trait adds to their reproductive peculiarities: female sharks can give birth without fertilization. The new mix Northern Ireland-U.S. research investigated the DNA of a ham... |
