Chalking one up for science vs religion

Apparently, atheists and agnostics performed very well in a survey of religious knowledge (on a par with Jews and Mormons and better than Protestants and Catholics) on questions about the core teachings, history and leading figures of major world religions. More about that here. But it wasn’t the survey I was interested in in particular rather their nice chalkboard graphic, which I’ve now adapted and sloganised.

The idea for the benzene smiley is from Tak as featured on the Reactive Reports chemistry blog.

Latest science stuff

Latest science stuff from Sciencebase:

  • It’s like, okay to say like – Teenage vernacular has always confused adults, particularly when the terminology seems to fly in the face of conventional grammar. Of course, any cunning linguist will tell you that language evolves and that yesterday’s perfect grammar rule is often tomorrow’s quaintly archaic phrasing. Moreover, the errant use of the word “like”, which often like litters youthful conversation is merely the current filler word, the um and ah if you will of street and schoolyard vernacular. It’s merely a part of yoof culture, innit? Get over it, Emma, why don’t ya?
  • Is chemistry worth it? – One in every five pounds in the UK economy is dependent on developments in chemistry research (£250billion, in other words), according to a new report published today. Science is Vital. It really is. Cut the cuts.
  • Enjoy yourself…it’s later than you think! – There is a 50 per cent chance that time will end within the next 3.7 billion years, according to a new model of the universe.
  • How to Memorize the Periodic Table With a Song – Kind of these people to link to my site, but I take issue with the idea of learning Tom Lehrer's song as a means to chemical education. It's fun and might help you remember the names of the elements, but learning this song is not going to give you any insights into the nature of the Periodic Table, the words fit the tune, but are in essentially random order, whereas the very essence of the PT is its order! And, another thing…the secret of all “memorization” is not repetition, it's association, you can memorize things much more effectively by finding or creating patterns and using those as a mnemonic.
  • Metallic sponge – An area the size of a football pitch within a porous MOF could be used to store hydrogen for use in safer fuel cell vehicles or trap carbon dioxide for greenhouse gas amelioration.

  • Cosmic Log – How to spot quantum quackery – Forget the quantum bit. Do they really have a website called "Cosmic Log"?
  • FDA action against aromatase inhibitor supplements – Aromatase catalyzes the appropriately termed aromatization of testosterone to 17β-estradiol. Inhibitors are usually used in cancer therapy, but bodybuilders have been turning to supplements containing such inhibitors to help pump up their pectorals…
  • Material priorities in Europe – Materials sciences and engineering: European Science Foundation (MatSEEC), chaired by semiconductor expert Guenther Bauer of the University of Linz, Austria, has identified its first priority topics for the future of research in this field and will finalise and disseminate information and recommendations to its participating organisations and the research community in Europe by the end of 2010.

Yet more scientific news

Yet more science news from Sciencebase, it’s never ending:

  • Whooping cough epidemic suggests bacteria are adapting – Nine babies have died in California, and four in Australia, so far, in the worst epidemic of whooping cough in rich countries since vaccination became widespread in the 1950s. The main cause is a lack of re-vaccination, but the bacterium may also be adapting to beat vaccines.
  • Emergency bra – If a flu epidemic or some other emergent virus is heading our way this season, then what could make more sense than an emergency bra? : Unsnap, separate cups, breathe easy. A boon for couples or ladies with a friend…
  • ‘Crazy chemist’ drugs campaign criticised by scientists – You can spend twenty years promoting science, writing about chemistry, trying to persuade friends, family, contacts of all kinds that chemistry is not crazy and then some stupid arts graduate A-hole in government comes with the most crass anti-drugs campaign you could imagine and undoes all your efforts. Twots.
  • ‘Dry water’ could make a big splash commercially – An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide. 95% water the substance, discovered in the 1960s, is now being investigated as a possible tool for ameliorating rising CO2 levels in the atmosphere.
  • Sperm tweezers – Optoelectronic tweezers can distinguish between live and dead sperm cells, even if they aren't moving, according to new research in the USA.
  • Why exercise won’t make you thin – Contrary to the ranting of gym addicts: "If you want to lose a pound of body fat, then that requires you to run from Leeds to Nottingham, but if you want to do it through diet, you just have to skip a meal for seven days." Of course, going to the gym isn't purely about trying to lose weight, it's about overall fitness, muscle strength, flexibility, cardiovascular fitness and more…but according to the health news the health industry won't want you to hear it's not going to get you slim.

Calculating science writer

Fellow science writer and author of Black Bodies and Quantum Cats, Jennifer Ouellette has a new book out – The Calculus Diaries – which she attempts to de-traumatize those of us who were force-fed derivatives and integrals but perhaps never got past pi-r-squared.

The marketing blurb explains how mathematics can help you lose weight, win in Vegas and survive a zombie apocalypse. The book itself bridges the gap between one’s mathematical dysfunctionality and the real world. It’s the math(s) of everyday life and Ouelette immersed herself in it for a year in order to conquer and calculate. If De Niro and his ilk “live the life of their characters” in method acting, then this is “method science writing”.

There was no single factor that led Ouellette down this methodical path, more of a gradual realization that this might be a topic that would be far more interesting to her adult self than she had presumed back in high school. “We all have gaps in our broad base of knowledge, and while I am far more scientifically literate than the average American, I am woefully ignorant about math,” says Ouellette. “Sure, I can balance my checkbook and manage my personal finances, even figure out basic percentages, but that’s just basic arithmetic. Most of us just don’t resonate well to how the subject is traditionally taught. Our brains don’t work that way. But make it relevant to us in some tangible way, and we become far less resistant, even genuinely interested. At least that was my experience.”

How many stars can you see?

Ask a child how many stars they can see on a clear night, and the answer is likely to be some rather precise and yet strangely diffuse number like 200 and twenty-nine billion million thousand. An adult might suggest millions(?) with an inflection in their tone of voice to suggest that they are uncertain of that number and think it might be much higher.

Of course, the real answer is way, way lower. On a really clear night away from city lights and air pollution and with the best eyes in the world you would struggle to count just a couple of thousand visible to the naked eye. With a decent telescope you could see many more and, of course, there are literally (to paraphrase the late, great Carl Sagan) billions upon billions of the astral orbs in the universe as a whole. See “Ask a Scientist” on the ANL site where they suggest that there are 10 billion stars in the Milky Way and a possible 10 billion galaxies, which means 10 billion billion stars (that’s a 10 followed by 18 zeroes).

However, Sciencebase reader Luke McGuiness alerted me to an even more unimaginable estimate from Marcus Chown. In his book The Never-Ending Days of Being Dead, Chown suggests that there are 150 billion observable galaxies and probably about 500 billion in total in the universe, which puts the star count at 5000 billion billion, a few orders of magnitude higher than the ANL estimate. Although even more recent Hubble estimates suggest 300 billion stars per galaxy. So could be 150,000 billion billion stars…a number that’s starting sound like the kind of child’s exaggeration I mentioned earlier.

This brief post was inspired by a post on a futurology blog that suggested one might see millions and by a quick google that revealed the answer (Universe Today) I already thought of as being a couple of thousand. Across the globe their are probably about 6000 stars visible to the unaided eye.

  • Massive galaxy puts years on universe – When I was a kid, the textbooks said the universe was about 13 billion years old, well that's (ahem) three decades ago so it must be 13,000,000,030 years old now. But, oh know the discovery of a massive 10-billion-year-old galaxy hints at the universe being far, far older than we thought.

  • Anthropogenic Climate Change: It’s for real – There is consensus among thousands of scientists in "appropriate" fields that ACG is real. But, think about it. Even if it weren't, do we really want to carry on pumping pollution into the atmosphere, stripping away acres of trees, leaving species extinct, fouling the oceans, using up all our mineral reserves, burning filthy fossil fuels and generally failing to make our lives sustainable? Of course we don't.
  • Google Health update – New features make Google health more useful for its users, but do you really want to run the risk of some evil engineer getting hold of your blood pressure charts and knowing how much coffee you drink each day?
  • Understanding antioxidants – New on my SpectroscopyNOW column – Our bodies have various mechanisms to reduce free radical damage and to repair damage that occurs. Antioxidants are key to these defence mechanisms and work by breaking the free radical chain reaction or through metal ion chelation, which inhibits metal-catalysed free radical reactions. Among the most interesting antioxidants are the flavones, a type of flavonoid with the 2-phenylchromen-4-one backbone found naturally in cereals and herbs.

Social media and science

I was recently commissioned to write a short piece about the adoption of social media and networking tools by scientists for The Euroscientist. I briefly covered various aspects of the evolution of the web and the notion of a Facebook for Science. Of course, there are lots of networks out there and both Twitter and FriendFeed are being used to boost the interactivity of scientific conferences, but until we get to at least web 2.1 and the next step towards the semantic web (3.0), it doesn’t seem that the majority of scientists are actually taking to these tools.

I asked Brian Krueger of Labspaces for his thoughts on the topic and he was inspired to produce a fully fledged blog post.

I also asked Dave Munger of SEED, researchblogging.org and scienceblogging.org fame to answer a few questions about web 2.1 and he was more than willing to offer a few insights:

“I think for scientists to be fully engaged with the online world, they need to see something in it for them – something to change the way they currently do things,” he told me. “In other words, the online world has to offer them something they need and want. I think some sites and services like Mendeley [dubbed a last.fm for research papers] and perhaps my own site, ResearchBlogging.org are helping them see that. But much of what is currently being done online doesn’t directly help scientists do what they need to do, so they’re not engaging with it.”

Munger suggests that peer review might be the next area of revolution. “The peer review system as it stands is antiquated, slow, and ungainly,” he explains. “I think a system of post-publication review might work best. Scientists would publish their work as soon as they felt it was ready for broader consumption. Then they would submit to ‘publishers’ who would ensure that the work was reviewed, placing it in the appropriate ‘journal’ based on the research’s importance and quality.”

Munger suggests that this approach, rather than submitting to and getting reviewed by several journals in the hope of being placed in the most prestigious spot, would mean that each article would only be reviewed once, thus saving time and resources.

“Reviewers wouldn’t be asked to comment on so many manuscripts, and authors wouldn’t have to be constantly resubmitting,” he says. “PLoS is taking a leadership role in this post-publication review movement.”

In order for such a system to work it would have to be transparent and open so that readers could know why a particular article was selected for a particular journal. “This in turn will lead to even more online engagement as reviewers respond to each other, and readers and authors respond to the reviews,” adds Munger.

Open notebook chemist Jean-Claude Bradley (no relation) of Drexel University believes my couching this post in such a way is a case of writing from the perspective of the glass being half empty vs half full. “You can argue any situation from the standpoint that it is a failure because adoption is below some arbitrary number,” he told me. “We could argue that science itself is failing because most of the population are not scientists, etc.”

JC Bradley is very optimistic about the direction that Open Science is taking, indeed he believes more and more people are getting involved, even if the percentages have not increased beyond some arbitrary value. “I think that more people will become more open despite not necessarily agreeing with the philosophy as their hand is forced,” he adds and offers an example in a blogpost entitled Secrecy in Astronomy and the Open Science Ratchet.

He does concede that there are still obstacles to widespread adoption. “Right now, the bottleneck is just finding people who are willing to share, giving them simple tools and helping them,” he says. “I don’t think technology is the limiting factor. Having semantics magically appear without any effort whatsoever isn’t going to happen soon – even if such systems did exist someone still has to verify the information and correct it. But with a very tiny amount of effort it is possible to abstract semantic information from organic chemistry Open Notebooks – even if the people recording the notebook don’t do the abstracting – we’re doing that for the Todd group for example and putting their info into Reaction Attempts database. JC Bradley adds that, “Every field will have to solve the problem of easily representing their data in semantically meaningful ways but the key factor is finding people willing to share.

  • CRISPR X-rays – New on my SpectroscopyNOW column – "It would be exciting if a CRISPR-like system could be transferred into mammalian cells," Doudna told us, "where it might be engineered to silence the expression of deleterious host cell genes, or genes encoded by viral or bacterial pathogens. If this were possible, it could avoid complications of using the RNA interference (RNAi) pathway intrinsic to mammalian cells, which is currently the focus of many biotechnology and pharmaceutical companies."
