Capitalism proceeds through creative destruction. What is created is capitalism in a 'new and improved' form - and what is destroyed is self-sustaining capacity, livelihood and dignity of its innumerable and multiplied 'host organisms' into which all of us are drawn/seduced one way or another.
Life on the planet is being homogenized by the expanding human population and the frequent and rapid movement of people and goods, which carry invasive organisms with them. These invasives often flourish in their new ecosystems because, like the woolly adelgid, they have escaped their predators.
DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins.
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.
In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves.
The reason for natural selection's great success is that it provides a satisfying explanation of how evolution might have occurred: individual organisms vary, and if those variations are inherited, the successful ones will survive and propagate and pass down their desirable traits to succeeding generations.
The second-most abundant biopolymer on the planet is called chitin, and some 100 million tons of it are produced every year by organisms such as shrimps, crabs, scorpions, and butterflies. We thought if we could tune its properties, we could generate structures that are multifunctional out of a single part.
Even printed, on pages that are bound, sentences remain unsettled organisms. Years later, I can always reach out to smooth a stray hair. And yet, at a certain point, I must walk away, trusting them to do their work. I am left looking over my shoulder, wondering if I might have structured one more effectively.
The existence of common features in different forms of life indicates some relationship between the different organisms, and according to the concept of evolution, these relations stem from the circumstance that the higher organisms, in the course of millions of years, have gradually evolved from simpler ones.
CRISPR-enabled 'gene drives' enable us to make changes to the germ-line of organisms permanent such that changes spread through the entire wild population, including making species extinct on demand. Unlike nuclear weapons such technologies are not complex, expensive, and able to be kept secret for a long time.
As human beings, we are the only organisms that create for the sheer stupid pleasure of doing so. Whether it's laying out a garden, composing a new tune on the piano, writing a bit of poetry, manipulating a digital photo, redecorating a room, or inventing a new chili recipe - we are happiest when we are creating.
Hardships of early human life favored the evolution of certain cognitive tools, among them the ability to infer the presence of organisms that might do harm, to come up with causal narratives for natural events and to recognize that other people have minds of their own with their own beliefs, desires and intentions.
Human settlements are like living organisms. They must grow, and they will change. But we can decide on the nature of that growth - on the quality and the character of it - and where it ought to go. We don't have to scatter the building blocks of our civic life all over the countryside, destroying our towns and ruining farmland.
Injecting CO2 into an underground reservoir would certainly change the local environment and thus affect the organisms that live there. Some will thrive, and others will suffer. While we should minimize such impacts, they cannot be avoided completely. The same happens when one plows a field, builds a house or a road, or waters a lawn.
It once seemed that the most profound feats stemming from DNA-based science would spring from our ability to read and detect genes, which we call the science of genomics. But the real opportunities lie in our ability to write DNA, to synthesize new gene sequences and insert them into organisms, resulting in brand-new biological functions.
Democrats pride themselves on their commitment to science. Citing climate change, they contend that they are the party of truth, while Republicans are 'denialists.' But with respect to genetically modified organisms, many Democrats seem indifferent to science, and to be practicing a denialism of their own - perhaps more so than Republicans.
Titan has no liquid water on its surface, and any liquid water beneath its surface is inaccessible to us, as far as we know. It has hydrocarbon lakes, but we don't know of any organisms that could live in those, not at the temperatures that we find on Titan. Any reference to possible life in lakes on the surface of Titan is pure speculation.
You are literally never alone. While there are roughly 6.7 billion people on Earth, you may not feel that many of them at all care very much about your existence. But within your colon alone are living at least 1012 billion organisms, or roughly a thousand times the number of people on the planet. Stop your metabolic processes, and you stop theirs.
