If the most complex cells descended from the least complex ones (which is what it looks like), that’s not really something many researchers want to hear.
How can viruses have altruism if they are not alive? Let’s assume that this is not an argument for panpsychism (You are conscious, sure, but so is your coffee mug.) It seems to be an argument that viruses behave as life forms do.
What’s amazing is the way life, once started, exploits every avenue, and yet how DOES it get started?
As described, the authors’ explanation doesn’t follow. The Medusavirus substituting its own DNA for that of the host is no different from the cuckoo substituting its own offspring for another bird’s in a nest. The fact that the strategy works does not necessarily demonstrate a hereditary relationship between the two species.
Why this matters: Cancer cells avoid destruction by inhibiting a process (which is called necroptosis). And necroptosis happening when it shouldn’t “is linked to the damage from multiple sclerosis, Parkinson’s disease and tissue injury from blood flow loss.” Targeting these processes could be an avenue for treatment.
The researchers say that their results “challenge the notion that DNA replication is uniform and consistent”
A science writer compares the cell to human inventions and finds that it is indeed amazingly energy-efficient.
Of course it all just tumbled into existence and “natural selection” somehow organized everything. As if.
And it all happens without intelligence of any kind? “Expert guidance” without experts?
What then becomes of “bad design” arguments, like those of Nathan Lents? In a transient world, any solution can only be optimal for a given life, as it must be factored against other lives.
Researchers: It has long been believed that all of the genome segments must move together from cell to cell to cause an infection. But the new study shows this is not the case.
We say this a lot: That’s a lot of information to have simply come into being by natural selection acting on random mutation (Darwinism). It’s getting not only ridiculous but obviously ridiculous.
If the bacterial strategy is clearly identified, they should look for non-helpful microbes that have found a way to copy it (horizontal gene transfer?)
For centuries, researchers knew that Euglenids, a diversified family of aquatic unicellular organisms, could reshape their bodies in any number of elegant ways but no one knew why they did it. Some researchers think they now know: “Amongst biophysicists, metaboly was thought to be a way to swim in a fluid, where these cells live,” […]
