The 2018 Trump Administration Science Budget
Scientists don't do universal good.
Take Fritz Haber, for example. He invented the technique for synthesizing ammonia, which has been invaluable to agriculture. The food production for half the world's population depends on his method for producing nitrogen fertilizers. But he was also the "Father of Chemical Warfare". Hmm...
But it is easy to show that science is what propels technological development and that government-funded science is essential for this, so it is baffling why the administration want to cut the science budget of NIH by 22%, DOE by 15% and NSF by 13%. Yes, I know they want to cut overhead grants, and a sensible discussion about that is always useful, but who would then build the buildings in which science is done?
Are they doing it just to save money? In fact I might consider myself more of a fiscal conservative than most Republican politicians. Why? Because I would be in favor of keeping both the military and mandatory elements of the federal budget under control, whereas they wish to inflate the former (through blind ideology) and ignore the latter (through fear of losing votes).
Let's hope the Congress does its job and reverses this policy. As President Obama said in 2011, cutting investment in innovation is like lightening an overloaded airplane by removing its engines. It may make you feel like you're flying high at first, but it won't be long before you feel the impact.

How to Run a Conference
I go to quite a lot of scientific conferences - maybe 10-15 per year - and they all tend to be in posh hotels with entry restricted to those able to find the registration fee, which normally is hundreds of dollars, and which pays for renting the conference room at the posh hotel, speaker travel, exorbitant cookies etc.
Sometimes there are not many people there. I remember once flying all the way over from France to Seattle to give a talk to about 10 people. But many more than that would have been interested - its just that they were blocked by the gnashing costs. A very recent conference I was at had trouble attracting enough attendees, even though I know dozens of young local scientists would have liked to attend.
So here's what to do (for some of the conferences, at least):
(a) stop holding conferences in posh hotels - hold them in university lecture halls.
(b) stop providing free meals
(c) stop providing free coffee and cookies
(d) stop funding speaker travel
(e) reduce the registration costs as the conference approaches if there are not enough attendees
(f) let in all students free
Then conferences would be what they really should be: a transmission of passion and knowledge to an enthusiastic and inspired young audience.

TTU and UTC
![]() |
Tennessee Tech |
TTU and UTC should use their two best assets - their young enthusiastic faculty and their curious and bright students. These, and laptops, are all you need these days to perform first-class research. OK, some experimental equipment is useful too, but they have that of course.
I've always been of the opinion that research success is built from the grass roots upwards (this is why ORNL and UTK REALLY need to work together better to greatly increase the student participation in research at ORNL). This means that the faculty need to integrate research into undergraduate curricula earlier than at present, and need to encourage materially faculty who are doing productive research. With a solid foundation of lively undergrads performing research under faculty supervision, TTU and UTC will quickly increase their research profiles, and everyone will benefit from it.

No space for today's young Einsteins?
In a recent opinion piece in the Guardian the excellent science writer Philip Ball wonders whether a young Einstein could survive today, given the need for young scientists to get grants and publish work of immediate high impact. In fact, I think it might be easier for him to flourish. However, maybe he would be less likely to think about physics in the first place.
I'm no expert in the history of science, but from what I read Einstein's first paper, on capillarity, was published as an undergraduate in 1900 (when he was 21) in the then prestigious journal Annalen der Physik. Now, this would be entirely possible today, and getting the work published as a sole author in a prestigious journal would certainly make admissions tutors for graduate school sit up and notice. As a result, Einstein probably would probably be admitted into graduate school in theoretical physics. Instead, for some reason back then he did not go to 'graduate school'. Perhaps this is because they didn't exist, as such? The idea of paying people after a degree without them having to teach perhaps hadn't started up? So, instead, he had to do it the hard way, while working in a patent office, doing his PhD on the side. He was awarded it in 1905, the year he published four groundbreaking papers. Now, lets snap back to 2016. Any young theorist with five single author papers in a reputable journal would certainly be offered a postdoctoral position in a leading institute, if not already a professorship. By 1908 the significance of his work was beginning to be appreciated, as it would have been today as well, and he was made a Lecturer.
So I think it was tougher for the young Einstein 110 years ago to do his physics than it would have been for him today. However, another valid question is whether Western culture today is as generally conducive to free-flowing creative scientific thought as was the culture in Germany and Switzerland in the 1900s. Einstein wondered what free-fall really was, and what riding on beam of light would be like. Has there been a general dumbing down of today's youth and family life, and if so, does this mean that such questions might never even cross the minds of today's potential young Einsteins?

Peer Review - Do Away with It!
The concept that a piece of research should not be reviewed by other experts in the field is, of course, ridiculous. But I think doing away with peer review in its present form is feasible. I wrote about this in 2012, and reproduce what my ideas would be here, with some tweaks.
There are two major current problems: the cost of publishing and access, and the inequities of the peer review process. Both could be cured at once.
We need ONLY ONE, publicly-run, open-access scientific publishing domain to which ALL ARTICLES are uploaded for free, in whatever format wished for by the authors and without prior peer review. This domain would subsume all existing primary research publishing. After an initial, publically-funded development phase, the small costs of maintaining this domain could be obtained through discreet advertising revenues. The model thus obviates both the need for charging huge amounts for access to journals and the need to charge authors for each publication submitted.
Once an article is uploaded it will easily be able to be found by a keyword search, such as exists in PubMed or Web of Science. Reviewing would not be solicited but would be open and online, in the fashion of "comments" to a blog entry. Any given article might thus receive many or no reviews. PubPeer goes a step in this direction. However, in my opinion no reviews would be anonymous: only registered reviewers who have revealed their identities would be allowed to post comments.
Before entering comments, the qualifications of the commenter would be verified e.g. PhD in the field of the article. All may comment, even the unqualified, but their qualifications would be public. I would suggest separate comment threads for specialists and non-specialists. Many of the reviews, even from the specialists, are likely to be incompetent, but the reviews would also be open to review, and ranking, as would the reviews of the reviews etc.. The paper itself would be continuously modifiable by the authors (as in Wikipedia), to add results or respond to criticisms etc.
In the above system there would be no need for a decision to be made a priori as to whether an article is "of sufficient general interest" before publication - this would all be decided by the readers afterwards: a points system could be devised whereby an article gains prominence depending on how many times it is accessed from different computers, cited later on, and on the reviews received. As an article rises in points, so would its visibility in the web domain. Extremely hot articles would be expected to very rapidly gain prominence.
Any objections?

Matt Ridley Gets It Wrong
But now he is screwing up, expressing opinions that, if they catch on, could greatly set back the rate of technological progress. Here's what Ridley writes:
"Heretical as it may sound, “basic science” isn’t nearly as productive of new inventions as we tend to think. When you examine the history of innovation, you find, again and again, that scientific breakthroughs are the effect, not the cause, of technological change.....The discovery of the structure of DNA depended heavily on X-ray crystallography of biological molecules, a technique developed in the wool industry to try to improve textiles. "
Well, with the X-ray statement Ridley has it stunningly wrong. X-ray crystallography has been behind many billions of dollars of marketed technology, including drug discovery, biotechnology and materials design, but it absolutely was not developed in the wool industry. Leeds was the centre of the textile industry in Britain, and the university did a lot of textile research. I was an undergrad in the Astbury Centre for Biophysics in Leeds University. The textile connection was important, and W.T. Astbury looked in the 1920s and 1930s at X-ray diffraction from wool and other fibres. And he was a real pioneer, indeed. But Astbury was a university professor, not an industry researcher. And crystallography was not 'developed in the wool industry' but rather earlier in Germany by Roentgen and von Laue and then in Britain by the Braggs, Perutz, Crick and others. All were working in universities, doing basic research, and not in industry. Theirs was the work that formed the physical basis of modern X-ray crystallography and the 1953 DNA discovery.
Now, as Ridley stresses, often trial and error does indeed play a large role in discovery. Indeed, we use it ourselves, sometimes, when searching for new drugs. But today's high-tech discovery is no longer based on "practical men tinkering around until they have better machines". Any 'tinkering' these days is based on a solid scientific foundation, developed mostly by government-funded research.

The Overregulation of Science
Now, I'm not sure science is actually overregulated in this regard. After all, we do need expert guidance on how to deal with certain things. But what is certain is that the burdensome regulatory hurdles in place are counterproductive. The whole thing reminds me of vehicle inspection in Europe (and some US states). Europe requires high standards of vehicle maintenance: you can't drive your car there unless it is safe and meets minimum emissions standards. That's fine, and I appreciate its worth every time I see a filthy truck belching fumes on the I-40. And cars with brakes that work reduce crash risks. What I am against, however, is Europe's compulsory vehicle inspection. In Germany and the UK everyone must take time out and pay through the nose to get their car tested every year. That's overkill and not a cost-effective way to increase road safety. It would be much better to send everyone the book of requirements and tell them they can be randomly tested and, if their car doesn't measure up, fined. That would cut red tape and stop wasting everybody's time and money.
The same goes for science ethics. Rather than force us to dispiritingly wade through molasses every time, give us the book of rules, tell us we must obey it and that we can either volunteer to go through the committee (if we are uncertain about things) or run the risk of getting randomly investigated. That shifts the responsibility to scientists while eliminating wasteful, expensive and time-consuming procedures.

Faith in science? Really?
So here is a response, from one who 'speaks for science'.
As in other highly-technical fields, such as medicine, to be a scientist requires a lot of learning and training; typically at least 10 years of undergraduate and graduate study. Normally, although aware that medical doctors have differing opinions and levels of competence, people do not trust someone without an M.D. to perform their heart surgery or fix their inflamed knee. So why not trust scientists?
Well, this particular inflammation is of political origin, and the statement about big-government science schemes is at the core. However, in my opinion, most people are in favor of some big-government science schemes while they may be against others. Consider, for example, a palette of projects: weapons research (such as the Manhattan Project) and other high-tech defense initiatives, blockbuster drug design, supercomputing, biotechnology, alternative energy and climate. None of these fields can advance (or could have advanced) rapidly without cooperative public and private investment - I'd be happy to explain why later for those who don't know. Which of these initiatives people classify as worthwhile tends to depend on their political and world view. But these biases are often out of fear for political decisions based on the science discovered, and this conflation of science and policy is at the origin of the mistrust.
Take our own Center for Molecular Biophysics as an illustration of the difference between the two. Quite a bit of our research is on biofuels or the environmental cycling of mercury. Yet we don't advocate any particular political policy related to these fields - indeed, we don't even discuss political aspects much. As for me, I don't necessarily approve unilaterally adopting a US carbon tax or regulating US mercury emissions; these policy decisions by themselves might in fact have no real effect on the problems they are trying to address. But, like Reynolds, I am no expert on these particular questions. I don't know what other members of CMB think.
But where we do agree with each other is that we think it's important to understand the science behind biofuel production, and how mercury is transformed and transported in the environment. And so we try to understand what is needed to find technological solutions to bring down the cost of cellulosic ethanol, and we try to to understand what happens to mercury once it enters the food web.
Myself, being a 'believer' in the general worth of science and technology for mankind, I want to see all the above-mentioned palette of projects pushed forwards. The cost to the taxpayer is small relative to other, non-science big-government schemes, and the economic return on investment enormous. Scientific research arms the population with the facts. What policy to adopt in response to the facts can then be chosen by the people and their representatives. But if you don't have the facts in the first place, on what do you base a political decision? So why defund climate research, or epidemiological research at NIH, or research on mercury cycling?
There's no reason to 'trust' scientists more than anyone else in their advocacy for any particular policy, but cutting down scientific research itself, which is surely the corollary of not trusting scientists in general, will lead to a lurch back towards an age of ignorance. Who then, would there be to trust?

Why I'm Against Affirmative Action
NSF gives extra points to proposals in which PIs make special efforts to make campus visits and presentations at institutions that serve underrepresented groups, mentor early-career scientists and engineers from underrepresented groups, scientists who participate in conferences, workshops and field activities where diversity is a priority etc.
I think some aspects of affirmative action, and especially the Bundesrat decision, serve neither the underrepresented groups or anyone else. Quotas automatically decrease quality (because selection is not purely on achievement and suitability), discriminate against majority groups and lead to failure and inferiority complexes for those favored. Hence, I agree with the conservative Supreme Court Gratz v Bollinger decision which barred quotas and disagree with Grutter v Bollinger that allowed them in a different form. Further, affirmative action only makes sense to me if discrimination on the basis of nationality is removed. Right now, you can be a ethnic minority female disabled Romanian or Thai working in the U.S. but unless you are a U.S. citizen you cannot be an affirmative action beneficiary.
As for diversity, in science in the U.S. (not France or Germany) this happens naturally, and our lab has always been wonderfully diverse, with, for example, sometimes simultaneously members from more than 15 different countries, but that wasn't intentional, it just happened, and unfortunately it's not what myopically qualifies as diverse for the U.S. Government.
Nevertheless, especially in the U.S., there is enormous untapped talent in the economically disadvantaged population. Our efforts should go into encouraging economically disadvantaged kids and educating their parents, well before university, and it shouldn't matter what nationality, ethnicity or gender they are: white, black, Hispanic, Slovakian, Asian, disabled, French, American. Also, of course, those disadvantaged kids who prove themselves to be hard-working and talented need to have an opportunity to pursue higher education equal to their richer peers. Equal opportunity. No doors closed. Yes, all need to be given "a shot" but none propelled through on a soft cushion.
Notwithstanding, given the hypothetical situation where I must choose between two Ph.D. candidates with exactly the same grades: one rich and the other poor, I will choose the poor kid every time. Not through pity or positive discrimination or for championing underrepresented groups, but simply because I'm likely to get more bang for my buck from a kid who has fought their way out of the projects.
Now, let's get down to organizing those East Knoxville high school lectures...

Bunkum Politicians and Science
There are politicians who are plain ignorant, such as the Minnesota Congresswoman Michelle Bachmann who claimed that the HPV vaccine has “very significant consequences” citing the anecdotal case of a woman who had told her that her daughter “suffered mental retardation as a result of that vaccine.”
There are politicians who deny global warming, such as the Senator from Oklahoma, James Inhofe, who brilliantly states that Nature magazine is " a very liberal publication". Then there are the politicians who decry evolution or GM foods. In the eyes of the German Greens, for example, and the majority of the European Parliament, GM foods, as they are controlled by big corporations, have to be evil, and the science showing GM crops are harmless has to be wrong and biased. Many of the same promote alternative medicine, which, by definition, is medicine that has been proven not to work, or not been proven to work. [These politicians want to divert money that could be spent researching actual evidence-based treatments to quack remedies. Clever, eh? And why should their $60bn dollar alternative medicine industry need no external regulation? Either their remedies have a clinical effect or they don’t; and if they do they should be treated like any other drug.]
Science becomes political when it spurs political action. The divide here is not between ‘pro-science’ and ‘anti-science’ political parties at all. Rather, politicians and parties will always side with science when it suits their constituency or conforms to their interests. When not then they deny the science is right and cherry-pick anything that seems to confirm their prejudices.
In election season, let's pinpoint those who deny science for political ends. In the words of the President of the Royal Society Sir Paul Nurse, (a native of Norwich!) “We can’t sit by without exposing bunkum.”

Decoupling.....

I'm back in Heidelberg and gave a talk at a Chemistry Symposium here today (as, by the way, did Stefan Fischer, Petra Imhof and Tomasz Berezniak of our group). Tonight, at the symposium an Honorary Doctorate was awarded to Carl Djerassi, known for his 1950s work on the synthesis of norethindrone, the first effective oral contraceptive.
Now the decoupling of sex and reproduction is so highly unnatural that society never has learned how to deal with it. When sex was robbed of its primeval physiological potency, millions of years of evolution, that have hard-wired instincts and associated morals into us arising from sex causing babies, were, in an instant, rendered obsolete. This hard-wiring meant that society could not change as quickly, and, anyway, the sustained association of sex with disease persists. But what will happen should scientists eventually take the next step, eradicating the sexually-transmitted diseases, thus removing all physiological 'danger' whatsoever? Society challenges scientists, and then vice versa.

Reasons to be Cheerful..Part 3

What Really Drives a Scientist?
It's interesting to briefly reflect on how this, in the case of J.C. Smith, has evolved over time.
When I was a graduate student: I was driven by deep understanding.
Unsure, I needed to find out whether I could do scientific research.
I was hooked into my narrow theoretical subject: I didn't know it at the time, but, maybe sadly, I would never again master any subject so thoroughly. (Conversely, I knew little about anything else, and most seminars, even in my field, were gobble-de-gook!).
When I was a postdoc: I was driven by competition.
There was maturation and widening of experience, becoming a senior member of a group rather than a dumb 22-year-old grad student. This happened, in retrospect, so quickly and with me hardly noticing. But towards the end I was driven by the stressful, cut-throat fight for an independent position that consumes some researchers at this age. This was a time of rejection after rejection. For my present postdocs going through the same purgatory, I've been there and understand. In a tough social battle, the subject sometimes seemed to take second place, and winning, reaching the promised land, mattered most. In retrospect I should have relaxed and enjoyed the science more: the spectrum of opportunity was, and is, much wider than I had imagined.
When I was a junior group leader. I was just driven! A time of networking, lecturing, and energy.
As a junior group leader one is young and liberated, so endless creative energy is expended. Nothing stops you (except wise old institutional bureaucrats). I gave 44 research lectures all over the world in one year!
Here's where the diversification really picked up, spreading out into different areas of chemistry and biophysics. It's not the best strategy for recognition, but I was just too interested in learning about new subjects to stick to one narrow sub-field, and was also a bit of a daredevil, sticking my nose into projects of which I knew nothing (I used to be the guy who'd put on a green wig to make a fool of himself in a crowd just for a laugh).
I also learned during this period just how important the social element of science is. Many excellent scientists achieve little because they can't get on with other scientists. But I was gregarious - got on well with most people. So when some colleague came and asked how we could collaborate, I'd often dream up some questionable way of doing so.
A junior group leader needs to be able to devise research, supervise it and write it up. I always knew I could do that, even as an undergrad: it was actually doing science I wasn't sure about early on. In one's twenties and thirties in science, as in many jobs, one learns one's strengths and limitations, comes to terms with them, and devises a way forward playing to the strengths with the limitations on board. If that way forward is beneficial to society, you have a career.
As a senior guy. Driven by impact and quality improvement. No longer needing to prove oneself to anyone (or to oneself) in quite the same way, things get more serious and focussed. A range of techniques has been mastered and these, while still evolving, will probably form the core of what I get involved in in the next 10 years. So what happens now is a gradual, step-by-step expansion of known territories, simultaneously on many fronts. Herschbach said it's like rolling out a big red carpet which has no end. For me that carpet is more an area than rolling in one direction, with each co-worker working on a different part of the perimeter. I am helping one co-worker to push it out first on one side, then going over and helping another push elsewhere. A body of work expands, about 15 publications a year, and much of my time is thus spent trying to understand what co-workers have found then helping them formulate language that expresses as accurately as possible what these findings are and mean. Thousands of other scientists are pushing out their carpets, too, and their pushing helps unroll ours and vice versa. Where and how we push gets to be more important now: I'm driven by trying to improve the quality of I do, by applications to fields of importance for society, and by communication to non-scientists.
But sometimes I look up at a plaque on the wall at home, made and signed with generous thanks by 50 ex-co-workers. As a grad student, and even 5 years ago, I never thought about such a thing, but maybe that symbolic plaque drives me more than anything else.

Setting Fish Free Bridge

In some ways the fish are an analogy to what China is trying to do with basic science - set it free. Funding for basic science is now doubling in the space of two years. Sounds impressive (although the actual dollar numbers will in the near term only approach those of NSF or BES, not surpass them). But judging by what we saw at Shanghai Jiao Tong University the building infrastructure is also in place. What seemed to me to be missing was a critical mass of top quality faculty. SJTU has started this recruitment, and we talked to some recent recruitees - all originally Chinese who had been in top positions in North America. Indeed, one of the natural consequences for the USA is that this funding increase, when coupled to the equivalent defunding proposed by the US Congress, should lead to a potentially large proportion of the brilliant young Chinese, of the type that have been dominating the contests for leading science positions in the USA over the last 20 years, preferring the exciting challenges beckoning in their country of origin.
Scientists are fish in bags - we can swim only wherever we happen to be set free.

CAUTION: graphic descriptions of disease and violence below.
Excerpt from "JOKER ONE: A Marine Platoon's Story of Courage, Leadership, and Brotherhood" by Donovan Campbell.:
Now for Jeremy's Soapbox:
We just don't get it. Why do we just accept cancer, heart disease and the other deadly afflictions? We just seem to seem to grin our teeth and bear it. People must not care, and here's why - because they only spend 0.2% of their wealth on finding ways to stop diseases. The US GDP is about $13tr and yet according to the OECD we spend only $26bn on health R&D i.e., 0.2%. Obviously we just don't care. Yet there are 1.5M new cancer cases per year in the US, and 500k cancer deaths. 1 in 4 of us will die of it, and a further 1 in 4 from heart disease. This absolutely dwarfs anything terrorism will ever do to us. If we make the effort research WILL stop these diseases. If people knew that themselves and their loved ones would be spared these diseases, wouldn't they want more than 0.2% of their income dedicated to it? Apparently not. Life is indeed cheap. We live for today, and don't care of tomorrow. Needed basic research is not funded, promising molecules are not synthesized and tested and clinical trials go unperformed.
As for energy research, improving and encouraging homegrown energy sources, while not eliminating international conflict, will surely lessen the pressure to go and fight foreign wars. Yet we pump trillions into stalemate conflicts while neglecting this simple way forward for both national and energy security. Again we fail to get it.
Science can cure cancer, heart disease, Alzheimer's, multiple sclerosis and the other hellish diseases. Science can mitigate the need to fight foreign wars, increasing national security via energy independence with renewable energy. Curing dreaded diseases and achieving energy independence is possible. But it takes time and resources and the short-term nature of the financial world makes it difficult for industry to do the groundwork research needed.
Energy and health research and development should be a top priority over the next twenty years. We must make sure the world's brainiest kids go into science and receive the support and motivation they need to do their research.

Welcome, China, to the Club of Scientific Superpowers
This has been interpreted in gloomy terms as a "worrisome trend showing erosion of U.S. competitiveness" and as indicating that the "U.S. dominance in science is at risk".
I would look at things a different way. I would welcome China to the club of scientific superpowers, applaud their progress over the last decade (which does not seem to have been mirrored by India, which arguably could have done as well), and try to see what we can learn from it.
Well, the U.S., to its credit, has lead the world in welcoming qualified foreigners to populate its research universities and fuel the creative technological drive the future always requires. But since time immemorial (meaning, at least since I was first in the States in '85-'89!) we have bemoaned the number of homegrown graduate students in the sciences. Local kids just don't seem to get motivated and curious about finding things out.
Compare this with the sentiment embodied in the following quote in Time Magazine from Energy Secretary Chu on a trip to Beijing: "In the U.S., rock stars and sports stars are the glamour people. In China, it's scholars. Here, Nobel laureates are the equivalent of Britney Spears." If this is truly the case, look forward to a fair fraction of the best and brightest of the youth of the presently 1.3 billion Chinese keenly dedicating their creative abilities to science.
And if, as is likely, the U.S. cohort remains mired in banker/rock-star/NFL fantasyland then China will quickly swamp the science stats.
How, then, will the U.S. remain at the table? Maybe the only way will be to rapidly further step up immigration of qualified talent from China? Rapid immigration isn't impossible - just look at Vancouver which, in the blink of an eyelid, has quickly become 30% Chinese, albeit not uniquely of the highly-qualified variety. But whether such an influx happens in the U.S. may well depend on whether we will continue have the means to attract the brightest over here. If not......

Art of Science

"To understand the forces involved in the assembly of cell membranes, we pull membrane proteins apart. We embedded a red blood cell protein, glycophorin, in a cluster of detergent molecules called a micelle. Using the computer technique of molecular dynamics simulation, we grabbed glycophorin and pulled it apart. When we displayed the molecular surface of the micelle with the protein shown in outline form, the micelle seemed to be glaring back at us, perhaps giving us a view, at an emotional level, of the forces that hold membranes together."
