I like how their experiment was literally pitting ants against each other.

I did this a lot as a child. Find some random insect (beetle, spider, earthworm), pop it into an ant colony and spend hours watching the ensuing battle. Never thought of it as cruel, which is unsettling when I imagine what an alien species with superior intelligence might choose to do with us.

I did the same but I would not call it battle. It was like feeding lions with human slaves during Roman empire.

The article describes the microscopic plating but doesn't show it. Here's a picture! http://cdn.sci-news.com/images/enlarge8/image_9093_2e-Acromy... Source: http://www.sci-news.com/biology/acromyrmex-echinatior-biomin...

Another interesting animal, an iron snail: https://en.wikipedia.org/wiki/Scaly-foot_snail

Woah this sounds amazing.

Does anybody know whether there's more details available on the symbiotic bacteria that creates the iron sulfides based armor?

I couldn't find the zoological identifier for it, so it's hard to find across the web.

Even wearing chain mail I doubt you'd have a chance much higher than zero against a full grown tiger.

I don't know, properly made chainmail suit is bite and scratchproof. Might be able to wrestle the tiger into submission. Though the weight of the tiger is going to be a VERY HUGE issue. Give me a spear and I'll be willing though.

That should make for an interesting YouTube video.

On the condition that the tiger is a healthy adult in the wild, hungry, and has never been captive, and someone is standing nearby not to interfere but to hit the upload button after you’re slain.

I have seen footage of a tiger pushing down the head of a charging antelope with one paw. Human has no chance wrestling an adult tiger.

There are accounts of people killing bears bare handed (though I don't know how adult they are), so it may not be as far fetched.

I can't help empathizing with animals in such a situation. It must be like getting teleported into an otherwise empty room with a tiger in it. (Turns out that humans with chainmail fare a lot better than those without!)

I've seen a grown man turned into Filet American by an ordinary housecat with a grudge. A tiger is off the scale in terms of the damage that it will be able to do and no matter what body protection you wear short of a full body armor you will likely end up slightly dead.

I should have seen it coming. This or Miles O'Brien himself chiming in and telling us that trace amounts of exotic substances in medieval chain armour would have interfered with the transporter's Heisenberg compensators.

I wonder if these ants are immune to the effects of diatomaceous earth. Supposedly, DE pokes holes in the waxy coating over their exoskeleton and the ants die of the resulting dehydration.

Personal experience, the diatomaceous earth does nothing, it barely scares them off.

Also research: https://bioone.org/journals/journal-of-economic-entomology/v...

Two problems I think. First, the kind of bear and the age of the bear. The size and strength of bears range widely. Fighting a sun bear is somewhat reasonable. Fighting a grizzly, on the other hand.....

Second, video proof. I know this kind of things probably aren't taped, because the people are busy fighting for their life. But, still, I'd be skeptical before I see some proof, that a person fought and killed an healthy adult grizzly (or some other comparable types) without a firearm or trap.

Nature seems to be trying, using, iterating and reusing all over the place, walled gardens be damned.
