Zitat des Tages über Viren / Viruses:
Surveying the way viruses have been discovered in the past, I came to the conclusion that I could use my technology that I developed as a graduate student - DNA microarray technology - to create a chip that would simultaneously screen for all viruses ever discovered, and furthermore have the built-in capability of discovering new viruses.
With 30,000 deaths and 200,000 hospitalizations from the seasonal flu, those numbers are certainly higher than what we've seen of the swine flu. Protecting yourself from both viruses is very important.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
Mushrooms have many helpful nutrients, including beta glucans for immune enhancement, ergothioneines for antioxidative potentiation, nerve growth stimulators for helping brain function, and antimicrobial compounds for limiting viruses.
I was addicted to hacking, more for the intellectual challenge, the curiosity, the seduction of adventure; not for stealing, or causing damage or writing computer viruses.
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.
Know that the tiger mosquito - Aedes albopictus - sometimes spreads viruses that spread like Zika, so it may be able to spread Zika.
In terms of dangers, such as viruses, fraud or identity theft, I don't think we were thinking about that at all when we got started. If we had been worried about that, the net might have been better today, but we might not have even got there.
To get a human through a life, lives of broken bones, knock-me-over-with-a-feather susceptibility to myriad viruses, and whatever else might befall someone will cost money.
It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.
I think it would be over-exaggeration to think that there are millions of viruses ready to jump on us and bring us back to the 14th century. That would be looking over a ledge that isn't there.
Images contaminate us like viruses.
We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.
Tobacco, UV rays, viruses, heredity, and age are the main causes of cancer.
The risk from viruses is an unanswered question - and it won't be answered until you have had organs transplanted into humans over many years.
It's a bit weird, because I don't really know what people expect or think being political is; I just don't get it. What am I supposed to do as a pop star-stroke-revolutionary? Get up and put my balaclava on, go to the grocery store and then invent some Google viruses, and then go to rob a bank to fund my revolution on YouTube?
For the first time in history we can track the evolution of a pandemic in real time. Influenza viruses are notorious for their rapid mutation and unpredictable behaviour.
When the AIDS epidemic broke, because I happened to be a science nerd and knew a lot about viruses and a lot about that virus at the time, I felt a moral obligation to go out and try to stem the fear and get out and explain to people what the disease was and how it worked.
It turns out that viruses evolve from each other, like everything else. So if you look at the evolutionary tree of viruses, you can find parts of their genome that haven't changed over evolutionary time. You can recognize what may be a new virus by identifying this little piece of their genome that hasn't changed and is represented on the chip.
People may have said that without symptoms, you can't transmit Ebola. I'm not sure about that being 100 percent true. There's a lot of variation with viruses.
This year, 1996, has been designated the 'Year of the Vaccine,' commemorating the 200th anniversary of Edward Jenner's vaccination of James Phipps with cowpox virus and subsequent challenge with smallpox virus. Insight into the nature of viruses, and how viruses interact with mammalian cells, has evolved since the turn of the century.
Maybe I should mention it: I was not from the beginning mainly interested in papilloma virus; I was mainly interested in infectious agents in human cancer. So papilloma viruses came up as the most likely candidate from my viewpoint.
We're shaking loose viruses and dislodging them from their natural ecological limitations, places where they aren't very abundant and have competition, even within a single animal. We introduce them into a new, rich habitat called the human population, where they can flourish more abundantly and cause more trouble.
