The Top Secret DNA of a New, Incurable Botulinum Toxin

In scary science, scientists have discovered an incurable botulinum strain, whose DNA sequence they're keeping secret because of terrorism concerns.



Some people actually inject this stuff in their face to get rid of wrinkles. These are natural chemicals made by bacteria, and very recently, a team found a brand new strain.



And get this: if you inhale just thirteen one billionth of a gram, you would die from it!



The scientists say that they discovered this strain from the fecal matter of a baby that suffered from botulism.



It's the first new strain to be discovered in over forty years. And this is the first time that scientists have kept the DNA sequence secret because of concerns that terrorists could use information published about the DNA sequence (that codes for the toxin), to make a dangerously potent bioweapon.

Building Body Parts

Stem cell science, otherwise known as the devil's religion, has been advancing in leaps and bounds. There was the news recently, where scientists sampled 3D printed working mini human kidneys.



And, now, in very awesome news, for the very first time, a research team has been able to grow human heart tissue that beats autonomously. What they said:



How they coaxed these reprogrammed skin cells into becoming heart tissue cells, I'm not sure. But, the principal point, after this coaxing, you have MCP cells.



They (the scientists) then took a decellularized mouse heart (which is a mouse heart with all the cells taken out, leaving a framework for the new cells), and repopulated it with MCP cells.

And, after several weeks, not only was the mouse heart rebuilt, but it was beating forty to fifty times per minute. So, ultimately, in amazing advance, obviously there's still a lot of room to improve, and they have to, because the human heart beats sixty to a hundred times per minute.

But, with one person dying from heart disease, every thirty four seconds, this is a huge, huge deal.
