Comment Re:Honesty? (Score 2) 440

80% crap? No. Science papers either generate more questions that are followed up by colleagues and competitors, or are crap nobody is influenced by, nobody cites, and nobody reads. Mistakes get caught--the second paper I wrote as a graduate student tore a well established professor a new asshole over a mistake he had published. I didn't care that I was a nobody and kowtow to the bigshot, I saw a mistake made on what was my thesis project and went for the jugular. I replicated the results, added more data, and aside from minor edits from my advisor I wrote the paper all on my own. I didn't do anything special and I'd expect the average grad student to do the same. We're trained to take the rank of somebody with a grain of salt including all the way up to Nobel laureates. A lab I was in collaborated with one a few years before he earned the prize. We (the grad students and postdocs--the bottom rungs of the scientific ladder) thought of him as somebody who was very bright, very aggressive, and who was almost always right but definitely did not dot the i's and cross the t's. If he made a mistake (rare) or went too far too fast (often) we made a note of it, knowing in our supporting role we'd have to run extra experiments to check it out. None of this is special, it's everyday workaday science from a nobody in the trenches.

Contrast that with an attempt at conspiracy. A nobody, one who's already gotten used to not trusting everything a Nobel laureate or National Academy member says, is going to tease that apparent mistake apart, find another, and another, and then smell blood and scientific glory in equal measures. And that nobody is pretty much everybody in science.

The military funds far more than weapons R&D. I've worked on a project to develop insecticides against mosquitoes that was funded by the US military. There are no weapon aspects, it was to protect American troops against diseases (dengue, malaria, etc.) that some species of mosquitoes can spread. The military has funded things that seem off the wall, like marine biology research trying to figure out a why jellyfish light up in the wake of a ship. Naval aviators have found their way back to carriers by following the carrier's fluorescent wake, but the same could be used by an enemy and the Navy wanted a way to make it stop. Didn't work out, but there is some interesting basic research on jellyfish and Green Fluorescent Protein that was produced as a result. The military also funds vaccine and antibiotic research, research into new surgical techniques, prosthetics, renewable energy sources (ie biodiesel), and a lot of other non-weapons research.

"A key part of the problem is that too many of today's researchers are only trained in the techniques that were made elegant 100 years ago and naturally see the increasing use of newer technology as a threat to their way of life."

I do biological research for a living, and have done so for many years, in multiple different fields, in different universities and now in the biotech/pharma industry. No technique I use existed 100 years ago any more than any technique a programmer uses existed 100 years ago. The majority of biochemistry and molecular biology techniques that I use have their primitive origins in the 1960s-1990s, depending on what the technique is, and the overwhelming majority have been heavily modified, adapted, repurposed, and improved since their introduction. Far from being afraid of new technologies and new techniques biologists are absolutely driven to use them, find them, adapt them, and invent them. Who do you think comes up with new techniques, including computer simulations relevant to biological research? People who do biological research of course! There are whole research journals devoted to nothing but new techniques, every one of them invented by some variety of biologist! There are hundreds of biotechnology companies where biologists do little else besides come up with new techniques (yes, including computer simulations and programs) that they can then package and sell to other biologists. Pharmaceutical companies spend many millions of dollars testing new techniques--I've got several different projects assigned to me right now that are nothing but testing and adapting new technologies. A pharmaceutical company that is not constantly innovating goes bankrupt, and a biologist who doesn't innovate is an unemployed and starving biologist.

"Really, this will likely be quickly quashed by the Pharmas. Or they will patent a delivery transport - with the only FDA-approved administration protocol."

Those actions are pretty much diametrically opposed. Option one, quash something that's already known presumably by managing to get a hold of the IP (good luck) and then sitting on it for years using a minimum of effort and cost. Option two, take something that works only on tuberculosis culture, do the R&D to make it work in humans, get it through clinical trials, then manufacture it and try to make a profit. Tuberculosis is a grand master at hide and go seek. It lives inside of human cells part of the time so delivering the vitamin C/vitamin C derivative is non-trivial. Even for a pathogen hanging out nekkid in the bloodstream the delivery of the drug to its target is non-trivial, 10 years and $1 billion of R&D is the rule of thumb to get to FDA approval from early stage research.

"I'm sure that there are certain sequences of nucleic acid or protein that, once synthesized and not "contained" could represent an existential threat to life on this planet."

Nope. Nucleic acid is not terribly stable stuff and for relatively short sequences every possible combination already exists in nature. Proteins aren't terrifically stable either and the vast majority require a three dimensional fold on top of the chemical structure in order to function. You can get rid of that fold-denature the protein-by a large number of means. Even if you still have properly folded protein its activity is heavily impacted by temperature, pH, presence of salts, concentration, etc. Life has evolved over billions of years to consume, break down, and reuse nucleic acids and proteins. The risk factor is around that of somebody manipulating water to go all ice-nine on us.

This is the exact opposite of what has been happening. Public universities have had their budgets repeatedly slashed over the last several decades. A state university used to get about 80% of its total budget from the state. Due to those budget cuts a state university is lucky to have 25%, and some get less than 10%.

"Discovery of DNA was an utterly world changing event, yet it appeared rather recently."

The history is more complex than that. Friderich Miescher first isolated what he called nuclein (now nucleic acids) from white blood cells in 1869. The work wasn't published until 1871 because the substance was a fundamentally different compound (organic chemistry was still fairly primitive). He did demonstrate that nuclein was from the nucleus and that it contained nitrogen and phosphorus but not sulfur. While he suggested that nuclein might play a role in heredity the thinking of the time was that heredity was too complex for merely one type of molecule to account for it. Albrecht Kossel later received a Nobel for working out much of the chemical structure of nucleic acids, from 1885 to 1901 he isolated and characterized adenine, cytosine, guanine, thymine, and uracil, the bases that make up DNA and RNA. However it wasn't until 1952 that it was shown that DNA rather than protein was the genetic material by the Hershey-Chase experiment. The DNA double helix was described in 1953, that proteins were encoded in triplet codons demonstrated in 1961 and all 64 codons in the "universal" code deciphered by the end of the 1960's. Eventually we come to PCR, exogenous protein expression, genome sequencing, etc. but there are a lot of small steps before we get to the current revolution, which from the point of view of a biologist isn't so revolutionary. To a public (and that includes us biologists at least as far as our non-professional lives are concerned) having to get used to genetically modified crops, human insulin produced by bacteria, the possibility of personal genome sequencing, etc. is fairly large and sudden.

”Yes, but things like how DNA and ribosomes work, and the basic molecular machinery would have already been set in stone even in bacteria that old.”

Abiogenesis is thought to have taken place somewhere between 3.9 and 3.5 billion years ago and these traces of life (textures on the surface of sandstone that have altered C12/C13 ratios suggestive of life) are dated 3.49 billion years ago. Calling them bacteria, or even saying that they had DNA and/or ribosomes, may be presumptuous. They’re old enough that conditions of the RNA world hypothesis might still apply. They might not have DNA at all but use RNA (or something else) as genetic material. They might use RNA instead of proteins for catalysis, which could obviate the need for protein-building ribosomes. This life might not be cellular, could just be primitive liposomes that chaotically break and reform, briefly shielding some set of catalytic molecules that when you average them out over a large area—say a cubic millimeter—the whole system is able to keep functioning and making more of itself.

But let’s ignore all of that and say that this stuff, whatever it is, has DNA. Does it only use the four canonical bases or does it use them and/or something else? How good is it at keeping deoxyribonucleic acids from being used alongside ribonucleic acids, or is a mix important in some function(s) at this very early stage? Suppose it does use just the four canonical bases, and just the four (five) bases for RNA, and has ribosomes, and has the central dogma in place of DNA->RNA->protein. What’s the protein like? Is the universal* genetic code in place at this point? Are there just 20 amino acids, the same 20 currently in use, and are they encoded by triplet codons? After all valine, leucine, and isoleucine are pretty much the same as far as protein biochemistry is concerned and usually can substitute for each other with little or no impact, so why have all three? Could there be a different set of amino acids, one that is potentially encoded by pairs of codons or mixed pairs and triplets?

Let’s ignore all of that and say we’ve got life, actual cellular life, that uses DNA with just the four bases, with negligible confusion with RNA, that the mRNA and tRNA and ribosomes are all worked out (and ignoring ongoing evolution), with just the 20 amino acids using the universal* genetic code. Does this organism make its own cellular membrane? There’s a whole bunch of synthesis involved with making the components of a membrane. Does it use cholesterol or other steroids? A modern cell membrane has more than phospholipids. Does it have a cell wall? That’s a completely different set of questions as there are many different cell wall structures and components in modern prokaryotes. What is the energy source for these organisms? Are they heterotrophic? How? Are they photosynthetic? How? Are they sulfur-reducing prokaryotes? How? Are they predatory? Do they secrete chemical compounds that lyse their neighboring prokaryotes? How?

It’s trivially easy to ask questions about basic chemistry, biochemistry, and genetics when it comes to these organisms, assuming of course we would grant them as being alive, when we’re dealing with something from 3.49 billion years ago. I do not necessarily agree with “fine tuning” either since there are geologically short periods of time that witness tremendous changes in life forms. The emergence of aerobic life about 2.5 billion years ago is one such point; oxygen would likely have been poisonous to the life forms in TFA. The emergence of eukaryotes about 1.6-2.1 billion years ago would be another, as would multicellular life appearing shortly afterwards. Throughout all of this the archaea, bacteria, and/or their ancestors would be present, and would be evolving in response to their changing environment.

I happen to have done some work in entomology so I have to mention insect evolution. The Paleozoic period is 541 to about 250 million years ago. The oldest definitive insect fossil is Rhyniognatha hirsti and dates to about 400 million years ago, about the same time that the first terrestrial ecosystems were being formed. Beetles didn’t emerge until 300 million years ago and there are now nearly 400,000 known species. 220 million years ago—well after the Paleozoic—the mosquito and the house fly diverged. The diet, ecology, reproductive strategies, and mouth parts of modern mosquitoes and house flies are radically different. I’ve done work on mosquitoes and their evolution is (unfortunately for half the world’s population) very interesting. They are arguably the worst spreaders of disease, being vectors of malaria, dengue fever, yellow fever, chikungunya, West Nile, several different encephalitis-causing viruses, and heartworm. Insecticide resistance is exploding and speciations are being observed in disease vector mosquitoes. Climate change is permitting formerly tropical mosquitoes to move into new territories and new speciation events are inevitable. Sure someone could protest that they’re still bugs with six legs, but then humans and turtles are still just tetrapods and those have been around for almost as long as insects.

The lack of human testing is a pretty big issue. I went to an early stages of drug discovery conference last year and remember one of the speakers referring to clinical trials as "the place where drug candidates go to die." However the articles linked to in TFA are very light on details so we don't really know what they have tested at all.

There are five different plasmodium species that can infect and cause disease in humans and we don't know which one(s) this group looked into. Probably P. malariae, and if effective on just one of the species it would still be wonderful news, but we don't know from TFA. The other problem is that the drug "killed resistant parasites instantly." What does that mean? Do they maintain drug resistant plasmodium strains in their lab and when you have them in some petri dish with tissue culture medium that you can instantly kill them by adding the compound? If that's all they've got then it's not nearly as impressive as the article lets on. Malarial pathogens spend a lot of time inside of cells, both inside of red blood cells and also inside of cells in the liver, hiding from the host immune system and any anti-malarial drugs. The life cycle inside the host is fairly complex with different malarial stages having different responses to any drug administered. This is why traditional malaria treatments are multiple doses over at least several days. The other problem is that the animal model for malaria disease isn't very good. Again, we don't know from the articles linked in TFA exactly what animal model they used, but it's probably a mouse model. In that case, it's already known to be easier to kill malarial infections in the model than in an actual infection in humans.

I share your wish that the research group has lots of luck in their upcoming clinical trials; it sounds like they've gone about as far as they can without testing on the actual disease in human patients. I'm just not optimistic as clinical trials are difficult to pass, a one pill cure just sounds too good to be true, and then your comments about the drug class itself.

Yes, there are a hundred coelacanth species, from dozens of genera, from a half dozen families, grouped into at least two suborders fitting into the order Coelacanthiformes. The taxonomic equivalent for dogs is the order Carnivora. Do you really wish to make a claim roughly equivalent to claiming that bears, badgers, and bobcats could all be due to variety existing in the same Carnivora genome? Keep in mind that Carnivora is only a little more than one-tenth the age of Coelacanthiformes, yet genetic basics like chromosome number can be wildly different. Just within family Ursidae the giant panda has 42 chromosomes, the spectacled bear 52, and the grizzly 74. From this comparison then it is a good bet that the coelacanth genomes of today are quite different from what existed 360 million years ago.

You're a bit muddled in your terms. Darwinian evolution is a collection of ideas which in Darwin's time didn't include mutation. He knew that species change over time, he knew that every group of organisms descended from a common ancestor, he knew that species multiplied by splitting into daughter species, he knew that speciation occurs through gradual processes rather than by saltation (sudden emergence of representatives of a new type), and he gave us one of the mechanisms of evolution: natural selection. Darwin didn't know the origin of new genetic information: mutation. In fact the merging of genetics and natural selection into the neo-Darwinian synthesis didn't happen until around 60 years after Darwin died. You're not getting genetic drift right either.

It is completely accurate to say that the only way species don't evolve is if they go extinct. At the most basic level evolution is simply the change in allele frequency in a population over time. Get a mutation, the allele frequency changes. Natural selection kills something off, ignoring clonal populations that's a change in allele frequency. Whether or not a change is necessary for survival is looking at it wrong. After all, other members of the species are getting along just fine without some specific mutation. A better way of looking at it is to ask if the mutation is compatible with survival. Does the mutation result in a nonviable organism? That's bad. Does it do nothing? Fine. Does it give you an advantage under some or all situations? That's good and as a result you might get more offspring and over time produce a large shift in allele frequency. These changes brought about by mutation and selection (and other evolutionary mechanisms) build up over time and new species inevitably result. There's nothing religious about it.

Of course biologists do: coelacanths (and insects, and everything else) are evolving. Over the 360 million years coelacanths have been around there have been countless new mutations and new environmental pressures that have shaped the coelacanths. We know of around a hundred coelacanth species that are grouped into not only multiple genera, but multiple families which we can identify from changes in skeletal structure and which we can use as index fossils. They hit upon a successful basic body form a long time ago but they've been evolving the whole time. The only way a species can't evolve is if it goes extinct.
