    Boas!

    Organism without a brain creates external memories for navigation
    The slime mold stores a record of where it's been using, well, slime.

    É (provavelmente) o olho de uma Architeuthis (lula gigante).

    Used contact lens solution hosts giant virus, ecosystem of parasites
    "Virus factories" and more are found in an amoeba within contact lens fluid.
    ...
    In July of last year, researchers in France described a rather disturbing example of what could happen if you're not careful about cleaning your contact lenses. A 17-year-old patient had been wearing monthly lenses well past their expiration date, and rinsing them with a cleaning solution she'd diluted with tap water. The end result was an eye infection. Luckily, a bit of care managed to clear it up.

    In the meantime, the people who treated her dumped some of the solution out of her contact lens case and started trying to culture any parasites that would grow out of it. In the end, they got an entire ecosystem—all contained inside a single strain of amoeba. Among the parasites-within-parasites were a giant virus, a virus that targets that virus, and a mobile piece of DNA that can end up inserting into either of them.

    mesmo...eu já vi naquela série do Discovery a pescarem uns com 500 Kg e não têm olhos daquele tamanho, por isso o 'dono' daquele devia ser um monstro

    Scientists discover living power cables made from bacteria
    Three years ago, scientists discovered electric currents running through the seabed — but they had no idea what was causing it. But now, researchers from Denmark and the United States believe they have the answer: bacteria that function as living electric cables. In a remarkable case of biological engineering, scientists have confirmed that each tiny section of the bacteria contains a bundle of insulated wires that leads an electric current from one end to the other.
    When black widow spiders make guns
    Spiders, it turns out, are even deadlier than we previously believed. Not only can they bite, but they help construct accurate guns.

    Monkeys of various ranks like to have sex with each other — but only when no one’s looking
    Life is tough for male and female macaques monkeys — especially when they’re horny. Like many primate species, their sex life is right out there in the open for everyone to see, including alpha males and alpha females who do their darndest to prevent low ranking monkeys from having sex with each other. And indeed, as a recent study by Anne Overduin-de Vries has revealed, monkeys will avoid having sex when troublesome bystanders are around — but things change when no one’s looking.

    Brazil To Clone Wild Animals In Danger Of Extinction
    Brazilian scientists have announced that they are moving ahead with plans to clone a number of endangered species, a list of animals that includes the jaguar, maned wolf, and black lion. The groundbreaking initiative is being conducted by the Brasilia Zoological Garden in partnership with the Brazilian government's agricultural research agency, EMBRAPA. The researchers claim that they're not looking to repopulate habitats, but to increase the number of captive specimens available. But in the event of extreme cases, they admit that they're prepared to release these cloned animals into the wild.

    Horror of the Day: Tarantulas Migrate En Masse
    Every day I find a new thing to hate about spiders. This particular day, I found out that horny tarantulas come out of their burrows and go walking around in packs. Sometimes they go in groups of thousands along migration routes. Are you in the middle of one of these centers of horror?

    Chemical warfare on the reef
    Algae kill corals, corals muster fish, fish eat algae and become more toxic.

    There are lots of organisms that don't have a brain, but can still communicate. Bacteria coordinate their growth, plants signal distress and lure insects in with scents and coloring. Now, researchers have listened in on some of the communication going on in a coral reef, and found that the organisms are saying the equivalent of things like "help me!" and "die!" Finding Nemo, this isn't.

    Tasmanian devils get their own private island, to save them from extinction
    Tasmanian devils have a real problem, and it's called devil facial tumor disease — a contagious form of cancer that is decimating populations and threatening the entire species. So, in an effort to save them from complete annihilation, a special "insurance population" of devils will be relocated to the private Maria Islands where they'll be safe from the disease — and where an entirely new self-sustaining colony can now hopefully thrive.

    These beetles are officially the laziest creatures on Earth
    ...
    This recently discovered beetle species, native to Cambodia, has clearly come up with one of the sweeter deals in the animal kingdom, albeit completely at the cost of its dignity. These beetles have adapted to living inside the nests of the termite species Macrotermes gilvus, whose larvae have themselves evolved natural handles so that grown termites can carry them around, which allows the slow-moving larvae to reach their food much quicker.

    These beetles have now horned in on that racket by tricking the termites to carry them to food as well. The beetles have developed chemicals that can imitate those secreted by the termite larvae, which entices the adult termites to pick them up. There has been a cost for this laziness (besides the aforementioned dignity). The species is wingless and its eyes are almost blind, meaning the beetle can now only survive inside the warm confines of the termite nest.

    7 Bizarre Prehistoric Versions of Modern-Day Animals

If she did, then the prehistoric ages wouldn't have been filled with stupid and bizarre-looking prototypes of modern species that seemed doomed to fail from the start.

    New species of lion discovered at Ethiopian zoo
    Naturalists in Africa have long noted that some lions in Ethiopia look a bit different than regular lions, mostly on account of a dark mane that extends from the head, neck, and chest to the belly. They're also smaller and more compact.
    Watch this now. We bet you’ve never seen a more stunning video of a cheetah in your life.
    This is the first ever high-definition, super-slow-motion video footage of sprinting cheetahs, which — I think we can all agree — are basically the reason high-frame-rate video cameras were invented.
