Bacteria-Killing Viruses Wield an Iron Spike
sciencehabit writes "Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew what it was made of or exactly how it worked. Now a team of researchers has found a single iron atom at the head of the spike, a discovery that suggests phages enter bacteria in a different way than surmised (abstract)."
So, now that we have confirmation that viruses have discovered and now use iron weapons expect this to be the latest Syfy movie.

I always liked to fantasize it was a wooden one...
It's a bright future for people who like life. People who are happy with their handful of decades followed by decline and don't have the courage to live longer can ignore these things.
Brandon Sanderson is on to something.
A single iron atom isn't going to much of a sword. Iron swords work because the iron atoms support each other.
A lone iron atom might do something chemically like pretend to be a heme molecule to bypass the bacteria's defenses.
So not only do bacteria use tools, but crafted iron tools at that?
It is amazing what a sped up life cycle and evolution can do.
Strange that is is iron, on a single atom level it would not be any tougher then the other elements.
Troll is not a replacement for I disagree.
This proves once and for all my theory that bacteria are not werewolves OR vampires!

Sounds like the viruses discovered...
Maiden! Maiden! Maiden!
Never in a thousand years thought I'd have a reason to write that on slashdot.

So that's the medieval viruses. What did the stone-age viruses use?
Are Iranian viruses trying to obtain nuclear weapons? That might leave a mark.

Next you'll be telling me they have souls.
Thousands of years ago, Bacteriophages wielded a single atom of bronze at the tips of their protein spikes, before the discovery of iron. (Yes, Bronzium, element 39.5, tragically excluded from the Periodic Table by bigots who dislike elements with rational numbers of protons that are not also integers).
Extra credit for those of you who deduced how I came up with 39.5. And yes, I know I didn't weight it correctly, this is after all, a joke. If you want accuracy, you've come to the wrong place.
Those aren't spikes! Those are Iron Grips! The brand bacteriophages prefer.
Why not modify a bacteria that is fatal to the virus, a honeypot of sorts? The virus thinks it is the predator, when it reality it is the prey.
Actually, it's plenty important, but in the big picture it will probably take second seat compared to the complexity of viral assembly. Especially when talking about phages, the fully-assembled virus is (sometimes) a complex machinery that is literally "cocked" and ready to inject the genetic material like a gun: it can't be measured directly, but some estimates put the equivalent pressure for the packaged DNA at about 20 atmospheres.
Once you have a fully-assembled virus, the game is pretty much lost: they are fully activated and disseminated. If interested in stopping viral replication, it will likely be better to interrupt the process of production, assembly, or maturation. Of course, this assumes that you want to stop the virus: some phages make very handy little bacterial assassins and have useful commercial applications.
It seems to me that some medical person once explained to me something similar in the way the HIV virus works. Pierces some sort of cell and injects it's DNA, causes the injected cell to create more HIV, and so on.... It's been years since I heard this explanation, so maybe I have it wrong. Then again, maybe there's some sort of tie-in?
If nothing else, it appears the Iron Age began on Earth earlier than we were taught in history class... Just not by humans.
Outlaw iron spikes and the only virii that will have iron spikes will be criminals phages!
It could be used to deliver antibiotics directly into the bacteria. That would enable us to develop a new class of drugs.
I prefer the "u" in honour as it seems to be missing these days.
i remember seeing a TV Documentary on bacteriophage years ago. it was very interesting indeed.
using the search string "bacteriophages + Russia" will give you endless results and show that since Stalin's time this has been used there
one thing that was a surprise to learn from the documentary is that they seem to all be pretty much in sewage and then extracted and cultured from there.
they then test each strain of bacteriophage against an array of nasties and see which one that particular "phage" is effective against
it brings a whole new meaning to "being in the shit"
Do you know what it's like to fall in the mud and get kicked... in the head... with an iron boot? Of course you don't, no one does. It never happens. Sorry, Tablizer, that's a dumb question... skip that.
If I have seen further it is by stealing the Intellectual Property of giants.
No lasers?
I know the Russians were especially interested in this technique. The antibiotic era is not that old: there are still plenty of people now alive born before antibiotics were common. And there is some talk talk of reviving phage technology due to the declining effectiveness of antibiotics as bacteria evolve resistance.
