Quote of the Day
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.
Think of the earth as a living organism that is being attacked by billions of bacteria whose numbers double every forty years. Either the host dies, or the virus dies, or both die.
We can, for example, be fairly confident that either there will be a world without war or there won't be a world - at least, a world inhabited by creatures other than bacteria and beetles, with some scattering of others.
Life on earth is such a good story you cannot afford to miss the beginning... Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings.
Here at the Cold Spring Harbor Laboratory, we have genetically rearranged various viruses and bacteria as part of our medical research. In fact, we have been able to create entirely new types of DNA molecules by splicing together the genetic information from different organisms - recombinant DNA.
James D. Watson
When antibiotics became industrially produced following World War II, our quality of life and our longevity improved enormously. No one thought bacteria were going to become resistant.
Left to their own devices, epidemic diseases tend to follow the same basic process: A virus or bacteria infects a host, who typically becomes sick and in many cases dies. Along the way, the host infects others.
What you see is that the most outstanding feature of life's history is a constant domination by bacteria.
Stephen Jay Gould
From dead plant matter to nematodes to bacteria, never underestimate the cleverness of mushrooms to find new food!
In the womb, humans are free of microbes. Colonization begins during the journey down the birth canal, which is riddled with bacteria, some of which make their way onto the newborn's skin.
Robin Marantz Henig
As far as I am concerned, LGBT can only stand for leprosy, gonorrhea, bacteria, and tuberculosis, all of which are detrimental to human existence.
Salad bars are like a restaurant's lungs. They soak up the impurities and bacteria in the environment, leaving you with much cleaner air to enjoy.
I think the biggest thing is clean as you go. Wash all your knives, cutting boards, dishes, when you are done cooking, not look at a sink full of dishes after you are done. Cleaning as you go helps keep away cross contamination and you avoid having food borne bacteria.
Once you have speech, you don't have to wait for natural selection! If you want more strength, you build a stealth bomber; if you don't like bacteria, you invent penicillin; if you want to communicate faster, you invent the Internet. Once speech evolved, all of human life changed.
Everyone is trying to jump on the biomimic bandwagon. But a cork floor is not biomimicry. Neither is using bacteria to clean water.
We mostly don't get sick. Most often, bacteria are keeping us well.
I do definitely believe that there is life away from this planet. I mean, we've kind of established that with the fact that we found bacteria on meteorites, and we've kind of used that to backtrack and show how this Earth, this planet, could have formed the ability to sustain life in the first place.
We inherit every one of our genes, but we leave the womb without a single microbe. As we pass through our mother's birth canal, we begin to attract entire colonies of bacteria. By the time a child can crawl, he has been blanketed by an enormous, unseen cloud of microorganisms - a hundred trillion or more.
Back in 1983, the United States government approved the release of the first genetically modified organism. In this case, it was a bacteria that prevents frost on food crops.
We've all been sick; we're all afraid of infection. I think the easiest application to help people understand what quorum sensing is and why it's important to study is to tell them that if we could make the bacteria either deaf or mute, we could create new antibiotics.
You can find bacteria everywhere. They're invisible to us. I've never seen a bacterium, except under a microscope. They're so small, we don't see them, but they are everywhere.
If an alien visited Earth, they would take some note of humans, but probably spend most of their time trying to understand the dominant form of life on our planet - microorganisms like bacteria and viruses.
What's great about bacteria is you have a surprise every day waiting for you because they're so fast, they grow overnight.
A big tree seemed even more beautiful to me when I imagined thousands of tiny photosynthesis machines inside every leaf. So I went to MIT and worked on bacteria because that's where people knew the most about these switches, how to control the genetics.
By weight, you are more human than bacteria, because your cells are bigger, but by numbers, it's not even close.
Martin Luther King, Jr.
