Scientists have found the deadliest toxin in the world. They can't release any info on it because there's no antidote!

Scientists in California have found a new strain of the botulinum toxin. It's the deadliest toxin known to us. The problem? They haven't come up with an antidote.

As a result, they haven't released the DNA sequence to the public in case it gets into the wrong hands.

Just how toxic is it? An injection of 2 billionths of a gram would be enough to kill an adult.
