Zitat des Tages von Christian de Duve:
Our investigations were very fruitful. They led to the discovery of a new cell part, the lysosome, which received its name in 1955, and later of yet another organelle, the peroxisome.
Overcrowded cities are spawning increasingly lawless suburbs. Waste is accumulating in and around them, straining the capacity to deal with it.
If you want this planet to continue being habitable for everyone that lives here, you have to limit the number of inhabitants. Hunters do it by killing off the old or sick animals in a herd, but I don't think that's a very ethical way of limiting the population.
We have access to practical, ethical and scientifically established methods of birth control. So I think that is the most ethical way to reduce our population.
I followed lectures on the history, geography, economy and political organization of Sweden.
Although separating mitochondria and microsomes might appear worlds apart from the determination of the molecular weight of macromolecules, certain concepts were common to the two operations and could be usefully transposed from the latter to the former.
The cost of our success is the exhaustion of natural resources, leading to energy crises, climate change, pollution, and the destruction of our habitat. If you exhaust natural resources, there will be nothing left for your children. If we continue in the same direction, humankind is headed for some frightful ordeals, if not extinction.
When, in 1949, I decided to join the little band of early explorers who had followed Albert Claude in his pioneering expeditions, electron microscopy was still in its infancy.
In spite of the advances of medicine, deathly epidemics are more menacing than ever before.
What would help us preserve our natural resources are genetic traits that let us sacrifice the present for the sake of the future. You need wisdom to sacrifice something that is immediately useful or advantageous for the sake of something that will be important in the future.
I cannot look at a question and not try to find the answer, even if I don't know it.
When I disappear, I will disappear; there'll be nothing left.
I knew the lysosomes and peroxisomes because I had discovered them; I knew the mitochondria because I was interested in them. I knew the membrane system because my friend, George Palade, had worked on that.
Ribosomes contain RNA, messenger RNA provides the information, transfer RNAs brings the amino acids; so the protein-making machinery is an RNA machinery, completely.
