Zitat des Tages über Moleküle / Molecules:
I really think that effective acting has to do literally with the movement of molecules.
The recipe for a human doesn't fill up a shopping list as you may suspect. Just twenty-two elements can describe almost all of the molecules that are, at this moment, you.
My own training is in the field of neuroendocrinology and I really became very fascinated many years ago with the molecules of emotion, molecules that we call neuropeptides.
Quantum physics forms the foundation of chemistry, explaining how molecules are held together. It describes how real solids and materials behave and how electricity is conducted through them... It enabled the development of transistors, integrated circuits, lasers, LEDs, digital cameras and all the modern gadgetry that surrounds us.
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.
I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule?
To a synthetic chemist, the complex molecules of nature are as beautiful as any of her other creations. The perception of that beauty depends on the understanding of chemical structures and their transformations, and, as with a treasured work of art, deepens as the subject is studied, perhaps even to a level approaching romance.
Our world isn't made of earth, air and water or even molecules and atoms; our world is made of language.
Today we have big, crude instruments guided by intelligent surgeons, and we have little, stupid molecules of drugs that get dumped into the body, diffuse around and interfere with things as best they can. At present, medicine is unable to heal anything.
It would be great if you could cool the water and immobilise the molecules, though keeping the structure, because when it's frozen, when it's immobilised, you can have it in the electron microscope and the water will not evaporate because in the electron microscope, it must be under vacuum, and water at normal temperature evaporates.
Cryptochrome harnesses the energy of incoming blue light, but other molecules are probably needed to absorb light of other colors.
I used to be a health-care investor a long time ago in the public markets. One thing I learned that we tried to apply here is that investing in small molecules, trying to invest in the next treatment, there's an element of gambling to that.
When a liquid boils, the temperature has been raised to such a pitch that the evaporating molecules are sufficient in number and speed to lift off the air from the surface of the liquid and push it back en masse.
No matter how closely you examine the water, glucose, and electrolyte salts in the human brain, you can't find the point where these molecules became conscious.
The actual atoms and molecules that make up my brain and body today are not the same ones that I was born with on September 8, 1954, a half-century ago this month.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences.
No lens is quick enough to track the movement of the human body. The molecules are always moving.
I have lived much of my life among molecules. They are good company.
I'm exchanging molecules every 30 days with the natural world and in a spiritual sense I know I am a part of it and take my photographs from that emotional feeling within me, rather than from an emotional distance as a spectator.
It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally.
The atoms may be compared to the letters of the alphabet, which can be put together into innumerable ways to form words. So the atoms are combined in equal variety to form what are called molecules.
As a listener, we're looking for that person who kind of excites the molecules within us - who knows how to tell the story that resonates deeply to our core and almost prompts us into action. Fats Waller has been that person for decades. When people need a lift, sometimes they go to him. I know I do.
Better biofuels are a really big deal. That means we can precisely engineer the molecules in the fuel chain and optimize them along the way. So, if all goes well, they're going to have designer bugs in warm vats that are eating and digesting sugars to excrete better biofuels. I guess that's better living through bugs.
The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.
Ultimately, biological phenomena involve molecules, and understanding them involves understanding the underlying chemistry. In my opinion, this is a particularly exciting area of chemistry.
We went from a world where almost nobody knew anything about computers to a world where almost all of us are computer geeks for a huge fraction of our day. And I'd like to see that happen with the digital world of biological molecules, too.
The basic parts, the start-up molecules, can be supplied in abundance and don't have to be made by some elaborate process. That immediately makes things simpler.
According to materialistic science, any memory requires a material substrate, such as the neuronal network in the brain or the DNA molecules of the genes.
Traditional academic science describes human beings as highly developed animals and biological thinking machines. We appear to be Newtonian objects made of atoms, molecules, cells, tissues, and organs.
We know what molecules are needed to sense light - what turns that signal that detects light into an electrical signal. We know how smells are detected. But we have a vast number of senses for which we know what the signal is, but we don't know what the receiver is.
Agarikon contains antiviral molecules new to science. Researchers for pharmaceutical companies may have missed its potent antiviral properties. Our analyses show that the mycelial cultures of this mushroom are most active but that the fruitbodies, the natural form of the mushroom, are not.
If you asked me what caused aging, I would say free radicals and molecules, which spontaneously shift and form and cause damage in all our cells and genes. The body usually repairs and replaces the damage in these genes. But as you get older, the aging clock turns down those defenses.
You look at the floor and see the floor. I look at the floor and see molecules.
I'm aware there are certain products that are being advertised - food products - with 'no chemicals whatsoever.' Well, that would be pretty hard to arrange, since everything around us is made up of atoms and molecules - chemicals - including ourselves.
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
One day I discovered that one could get the barrier to internal rotation in ethane approximately right using this method. This was the beginning of my work on organic molecules.
