When we're hungry, food tends to look better to us than when we're not hungry. Blame it on a stomach "hunger hormone" by the name of ghrelin. A Montreal Neurological Institute study has been scrutinizing this in order to understand how to treat obesity. More food for thought follows in the full article, right after the jump. |

It would seem that the old maxim "Everything in moderation" still rings true today - too much of a good thing can actually be a bad thing. This may be especially true as far as technology is concerned. The reason: too many silver nanoparticles in today's consumer products may be killing off beneficial bacteria. More bacteriocidal news follows after the jump. |

It's common knowledge that the human race is made up of one species. Scientists have said, however, that our line was nearly split in two at some point in our history. The cause may have had something to do with living conditions in Africa. More splits occur in the full article after the jump. |

Bees make honey, everyone knows that. But more often than not, everyone overlooks their other, more important function in the food chain: natural and effective pollinators of plants. If bees were not around to pollinate, the world would definitely be a hungrier place - and such is the reason why we should be scared that plants are bees are now currently being killed off. The details in the full article. |

What's an extremely small, extremely common, and fond of bacteria? Simple: bacteriophages. There's more to these little critters than meets the eye, though - just check out a photo of them taken via electron microscope. For the picture and more infinitesimal news, turn to the full article after the jump. |

Sometimes,
ancient life finds the the oddest places within which to hide and to
leave signs. Take the case of this underground nuclear waste dump in
New Mexico, for example. Scientists recently discovered the remains of
ancient plant life in there. More "ancient" news follows after the jump. |

Sometimes, in order to understand something better, you have to take a look at its roots. Dr. Julie Baker and Kirstin Knox are doing just that, and the object of their study is the placenta. Apparently, there's more to the lifeline than meets the eye. More on the evolutionary origins of this peculiar organ in the full article, right after the jump |

If you've read the novel "War of the Worlds" by H.G. Wells, or if you've at least seen the movie, you know how important viruses were in the story. Thing is, viruses have a less dramatic - but no less important - role to play in real life, according to scientists. It has something to do with how they relate to cyanobacteria. More "viral" news spreads after the jump. |

This next story needs no further introduction. We'll just inform you that this is about a hybrid embryo created by Newcastle University scientists. Why hybrid, you ask? Well, it came from different species - humans and cows to be exact. The full details are in the full article. |

Just because we humans are at the top of the food chain doesn't mean we're the fastest evolving living being out there. We're just the success story of evolution. The fastest evolving creature out there - at a molecular level - aren't humans. It's not even a mammal. It's a reptile called the tuatara, which lives in New Zealand. More in the full article. |
