Top 144 Cells Quotes

Fuel cells create a better automobile that’s 50 percent more energy-efficient overall and sustainable from energy and safety perspectives.

We keep thinking that the human is evolving. No, the human has evolved to its extent. What’s happening now is the organization of humans: just like cells organize to form people, people are organizing to form humanity.

One of the great things about working on C. elegans was the fact that it was transparent, and so when I first heard that seminar describing GFP, and realised, ‘I work on this transparent animal, this is going to be terrific! I’ll be able to see the cells within the living animal.’

We have about 100 million cells interconnected in our brains. They communicate with one another through electrical signals.

It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.

Brain cells are normally not sensitive to light. So by introducing light-sensitive proteins into specific types of neurons, we can now selectively control that specific type of neuron by shining light in the brain.

Often, lectins can get in the way of important cells communicating with one another. And when that happens, the body’s response is usually inflammation or some other type of reaction to toxicity, like nausea, diarrhoea, or vomiting.

Windmills and solar cells are carbon-free sources of electricity. But they are costly. If you’ve been investing in those, give it up. That game is effectively over.

A key issue in developmental biology at that time was the problem of how cells underwent differentiation, with most workers concentrating on explanations in terms of changes in enzyme and gene regulation.

Almost always, when we have fights in movies, they’re done in these strange rooms where nothing gets broken. It’s almost like they’re in padded cells.

It’s incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.

Laser cooling opened a new route to ultralow temperature physics. Laser cooling experiments, with room temperature vacuum chambers and easy optical access, look very different from cryogenic cells with multi-layer thermal shielding around them.

Certainly I see no reason why society should prevent grieving parents from having a baby cloned from the cells of a dead child if they wish.

We evolved living in more sunlight than today. We make our own vitamin D when sunlight hits our skin cells. Many people living in the northern hemisphere, however, suffer from lower levels of vitamin D during the fall, winter and spring.

We know that our cells are speaking to each other.

If you want to help Africa, you should help them out of poverty, not try to build solar cells and windmills.

Battering down solar cells on the roofs of Wal-Marts in California. I think that will be some of the highest-return investments that anyone ever makes.

Nerve cells communicate with one another at specialized points called synapses. And these synapses are plastic – they can be modified by learning.

When I was in high school, I became interested in cytochemistry: chemical analysis under the microscope, and trying to understand the composition of cells.

Saturated fat is a fundamental building block for brain cells. It’s certainly interesting to consider that one of the richest sources of saturated fat in nature is human breast milk.

I learned about HeLa cells in my first basic biology class, and I just became completely obsessed with them from that point on.

Where he was, where his cells were, where his logistical channels were, how he communicated. Who his allies were. Who donated to them. I think it’s fair to say the entire range of sources were brought to bear.

In my lab, we are always thinking about how cells, bacterial cells, can talk to each other and then organize themselves into enormous groups that function in unison.

The number of cells in our bodies is defined by an equilibrium of opposing forces: mitosis adds cells, while programmed cell death removes them. Just as too much cell division can lead to a pathological increase in cell number, so can too little cell death.

Cancer essentially lives in us and becomes activated at some point, and then cells begin to psychotically divide. Initially, the cancer cell looks like other cells and the body invites it in.

I believe fuel cells could end the 100-year reign of the internal combustion engine.

I think hopefully we’ve got enough brain cells left to decide if our music is really worth something.

My lab looks at the ability of stress hormones to kill brain cells, and basically we are trying to understand on a molecular level how a neuron dies after a stroke, a seizure, Alzheimer’s, brain aging, and what these stress hormones do to make it worse.

It doesn’t matter whether you can or cannot achieve high temperature superconductivity or fuel cells, they will always be on the list because if you could achieve them they would be extremely valuable.

The bad news is that my thin melanoma has something called mitosis, which means the cancer cells are dividing and multiplying even as I write. My thin melanoma has already spread outside of the tumor and into the deep layers of skin.

We barely missed killing Bin Laden. There were numerous findings issued by the President to kill him. We rolled up terrorist cells. We stopped the millennium bombings.

I like knowing that the further back one traces any lineage, the narrower the path grows, to the haunt of just a few shaggy ancestors, with luck on their side, little gizmos in their cells and a future storied with impulses and choices that will ultimately define them.

Life is the division of human cells, a process which begins at conception.

In 1880 at the Military Hospital at Constantine, I discovered, on the edges of the pigmented spherical bodies in the blood of a patient suffering from malaria, filiform elements resembling flagellae which were moving very rapidly, displacing the neighbouring red cells.

Just when your ovaries should be brimming with youthful follicles, cancerous cells overtook mine, threatening to end my fertility and potentially my life.

A fundamental premise in cancer therapy is trying to identify how the metabolism of cancer cells differs from normal tissue. When differences are identified, it often paves the way for treatments that will disrupt the cancer’s metabolism while sparing normal tissue.

To become a celebrity, a name – and I’ve actually met some that speak of themselves in the third person – it’s scary. They become an object, not a human, complex, questioning thing where the cells are always changing.

Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?

In my second year, after moving to the Medical School, I began the courses of Anatomy and Physiology. I had begun to see that I was interested in cells and their functions.

I love to put myself in a situation where I get to break a few things and construct a few cells in me.

The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It’s just mind-boggling to think of all the different ways in which they’re arranged in a baby’s head.

Therefore, I reasoned that study of the cell cycle responsible for the reproduction of cells was important and might even be illuminating about the nature of life.

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.

In ‘The Violinist’s Thumb,’ I talk about the poignancy of cells leaking across the placenta into both the mother and the child.

Working out is incredibly boring. I swear it’s true that the bigger your muscles get, the fewer brain cells you have.

We carry stores of DNA in our nuclei that may have come in, at one time or another, from the fusion of ancestral cells and the linking of ancestral organisms in symbiosis. Our genomes are catalogues of instructions from all kinds of sources in nature, filed for all kinds of contingencies.

Man, like other organisms, is so perfectly coordinated that he may easily forget, whether awake or asleep, that he is a colony of cells in action, and that it is the cells which achieve, through him, what he has the illusion of accomplishing himself.

Epigenetics is very important. We are keeping a close eye on iPS cells and other genetic methods of reprogramming the epigenome.

To me, nothing else about a tree is so remarkable as the extreme delicacy of the mechanism by which it grows and lives: the fine, hair-like rootlets at the bottom and the microscopical cells of the leaves at the top.
