For the first time ever, a whole lab-grown kidney has been successfully transplanted into a rat, where it allowed the creature to process urine like a really kidney would—and it could someday save your life.
This is what you get when you take data from a CT scan and convert it into a format that can be read by a 3D-printer. It's a skeleton. But not just any skeleton. The 3D model you see here was printed while the rat whose bones it's based on was still alive. Intact. Still wrapped in muscle, skin and fur.
File this away under things you didn't want to know first thing Monday morning: a reportedly "shocking" quantity of bushmeat — including rat, goat and sheep meat — is being sold to the public illegally in east London marketplaces.
Scientists have managed to build an artificial jelly fish entirely from rat cells, which can pulse and swim when exposed to an electric field, just like its living counterpart.
In a battle of wits, humans and rats are way more evenly matched than you'd think. While we obviously have an advantage in overall intelligence, our ability to read situations and make decisions is actually no better than a rat's.
Rat are notorious pests, with populations throughout the world living off the scraps and garbage left behind by humans. Rats, it seems, are just born to mooch off humans, since they've gone down this same evolutionary path four different times.
About 90% of flowering plants require animals to pollinate them, and that includes about two-thirds of the world's crops. The extinction of pollinating organisms could spell disaster... but the very species that are killing them off could prove excellent substitutes.
Letting your mind wander allows you to be introspective, and to think in abstract ways most other animals cannot. And yet rats possess the same brain structures we use for introspection — which suggests deeper evolutionary roots for introspection and, by extension, consciousness itself.
Not all invasions come from marauding armies. You can devastate a place just by introducing a non-native species that creates dramatic and unexpected shifts in the dynamics of the ecosystem.
The single-celled parasite Toxoplasma gondii lives infects rats, but it needs to be inside a cat's digestive system in order to reproduce. The parasite actually alters the brain of its rat host so that it won't be afraid of cats.
Animal brains, ours included, have evolved to be powerfully aware of where we are at any given moment. But it turns out that our brains are surprisingly, frustratingly two-dimensional, and that we're only dimly aware of changes in altitude.
Not only are we smart, charming and pretty here at Gizmodo, we are also fantastically cultured. As the Chinese New Year is upon us, we would like to take this opportunity to wish all those celebrating it a smashing new year. As
a Chinese restaurant placemat our research informs us, the Chinese calendar cycles every…
In honor of the year of the rat and Chinese New Year (Feb. 7), iRiver's coating their rat/mouse-shaped Mplayer in gold. This seems like it's real gold, seeing as each one is individually numbered and comes in a limited edition box. However, it's only available in China, which means you're going to have to get your…
