Science Zombie Virus Drives Caterpillars To An Explosive Death

Scientists recently discovered something that was causing European gypsy moth caterpillars to behave very strangely. The caterpillars were infected by a deadly baculovirus, and with their last bits of strength, they did something that would be out of the question if they were healthy: they climbed out onto the very highest leaves of their tree in the middle of the day.

There, their diseased bodies split open, raining infected caterpillar guts onto the leaves and branches below. The death ritual is so bizarre, that scientists started using the term ”tree top disease” to describe the virus that caused it.

In a recent issue of Science magazine, researchers reveal the cause of this odd final act: a specific viral gene that drives infected caterpillars to die in a way that offers the best potential for spreading the virus that killed it…just like a zombie (ScienceDaily).

The virus “ends up using just about all of the caterpillar to make more virus, and there are other genes in the virus that then make the caterpillar melt. So it becomes a pool of millions of virus particles that end up dropping onto the foliage below where it can infect other moths that eat those leaves,” study co-author Kelli Hoover told National Geographic.

The New Helper.Net gives me great Anxiety... o.O;;
I want to see a video of this so bad.

So... don't eat caterpillars that you find on the top of a tree?

It's not that they're on the top of a tree, it's that their dead infected guts are on the leaves below the top of the tree D:
AFTER they get to the top of a tree. What would happen if I took one from the top where it explodes, and moved it to the bottom? Will it still explode, or will scurry on back up to teeter on the leaves for a moment before suicide bombing itself?

What do I look like, a guy that knows where to find a caterpillar in a tree?

And is anyone else curious as to what the caterpillar is sitting on in that picture?

Frog blast the vent core!
looks like moss that it is sitting on.. There is a type of fungus that does pretty much the same thing to certain types of insects, but I can't remember what it is called.

Yeah, I remember reading about something similar where a fungus infected ants and made them into zombies. They would go away from the fungus(to spread it further) and then stop, explode and spread spores all over the place.

Here it is: http://www.livescience.com/5631-zombie-ants-controlled-fungus.html

It's kind of creepy to be honest.

Oh Shi.. Don't wake the tiger!
^ yeah, it's creepy as hell

Oh Crap. Scientists are working on modifying the virus to combat gypsy moths, eh? I don't think that's such a good idea .

So many apples
Nature, you scary :eek:

AFAIK there are also snails and Ants that are prey to a mindcontrolling fungus. Which are forced to be eaten by Birds, who in turn are infected as well and help colonize the fungus in various places :p

I remember some mushroom spores that infect ants' brains so they climb to somewhere high and then the mushroom kills them and grows through the ant's head to infect more ants. COOL!

(Evol)ution is nothing without love.
So it moved from ants to caterpillars? Scary.

No. Catepillars have a virus while the ants are being murdered by a spore. There are many more lifeforms that turn the hosts into "zombies". Some parasites also do this.

I was mainly making a joke, but it does bring a question to the mind, will it ever reach more and more complex life forms? Who knows... It all depends on how the process itself works, and if it can adapt.

    I dunno if I ever mentioned it here, but my bot actually helped someone discover a new way to clip through walls.
  • tom_mai78101 tom_mai78101:
    However, not many folks heard about it, because it's currently only compatible with the latest dev builds of multi-system emulator, BizHawk.
  • jonas jonas:
    cool! do you have a video?
  • tom_mai78101 tom_mai78101:
    I have a GIF though
  • tom_mai78101 tom_mai78101:
    In the GIF, I've configured it so the lower the "Main Value" is, the better. I had to compress it pretty far down though.

    And this is the thread with the video that shows the wall clip. https://tasvideos.org/Forum/Topics/23453

    Hmm, about the Headline News, I noticed threads are being moved into the subforum (Health News, Environmental News, etc.). When that happens, the TH Forum Home page loses the articles, and instead would show old articles posted 1 or 2 weeks ago.
  • tom_mai78101 tom_mai78101:
    What do we do with the Home page?
  • Ghan Ghan:
    I added those forums to the filter for that widget.
  • tom_mai78101 tom_mai78101:
    Oh nice. They're back. Thanks.
  • tom_mai78101 tom_mai78101:
    Now I think it makes more sense for me to put news in their own subforums, without worry.
  • The Helper The Helper:
    Awesome Ghan thanks! I was purposely not moving the first 15 news articles in Headline news to the different subforums but I guess I don't have to do that now?
  • tom_mai78101 tom_mai78101:
    Question: Is there a way to remove thread redirects? It creates a copy of the moved thread and takes up space, and I am leaning towards wanting to remove them in the Headline News. But if they have an expiration date, I guess I'm fine with it.
  • The Helper The Helper:
    If you move a thread please leave a permanent redirect. You can delete any redirects after 6 months. The redirects are left to help Search Engines find the moved content.
  • tom_mai78101 tom_mai78101:
    What if you move the permanent redirect, not the thread?
  • The Helper The Helper:
    I think that works but I have not messed with it. You can delete redirects though if you have to that will not delete the original thread
  • The Helper The Helper:
    if a redirect ends up in the same forum as the post it goes to though I think the redirect drops or fails or something but they are not bugged out and when you are working on an indirect the original post is safe.
