It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria are the Gram-negative bacilli, and the most susceptible are the pyogenic cocci ... In addition to its possible use in the treatment of bacterial infections penicillin is certainly useful... for its power of inhibiting unwanted microbes in bacterial cultures so that penicillin insensitive bacteria can readily be isolated.
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
Most bacteria aren't bad. We breathe and eat and ingest gobs of bacteria every single moment of our lives. Our food is covered in bacteria. And you're breathing in bacteria all the time, and you mostly don't get sick.
It has occurred to me that possibly the white corpuscles may have the office of picking up and digesting bacterial organisms when by any means they find their way into the blood. The propensity exhibited by the leukocytes for picking up inorganic granules is well known, and that they may be able not only to pick up but to assimilate, and so dispose of, the bacteria which come in their way does not seem to me very improbable in view of the fact that amoebae, which resemble them so closely, feed upon bacteria and similar organisms.
For the first half of geological time our ancestors were bacteria. Most creatures still are bacteria, and each one of our trillions of cells is a colony of bacteria.
For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which together constitute a pair.
The male chromosome is an incomplete female chromosome. In other words the male is a walking abortion; aborted at the gene stage. To be male is to be deficient, emotionally limited; maleness is a deficiency disease and males are emotional cripples.
Geneticists in the early 1900s believed that nature - in an effort to avoid wasting precious space within chromosomes - would pack as many genes into each chromosome as possible.
What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
All these bacteria that coat our skin and live in our intestines, they fend off bad bacteria. They protect us. And you can't even digest your food without the bacteria that are in your gut. They have enzymes and proteins that allow you to metabolize foods you eat.
A person like Carole King could make up something, change it, and actually improve it.
Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty… I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.
I actually believe that you should not wash your jeans, ever. In Japan, they actually put them in the freezer. That kills the bacteria and makes them not smell anymore.
[Bacteria] have an incredibly complicated chemical lexicon that ... allows bacteria to be multicellular. In the spirit of TED they're doing things together because it makes a difference.
I never thought I would actually become a professional actor. I just kept going with it. One thing led to another.
There's a photograph of me in the transplant unit where I have a vomit bucket under one arm, I have my laptop on my knees, and I'm crying, not because, you know, I'm about to have a bone marrow transplant, but because I've missed a deadline!
