"Home library size has a very substantial effect on educational attainment,...
This is a large effect, both absolutely and in comparison with other influences on education,"

jdupuis | March 31, 2010From the April Communications of the ACM, the Kode Vicious column is on The Data-Structure Canon.
The reader question is:
In most areas of science there are a few basic underlying laws that inform the rest of the study of a given subject. Physics, chemistry, and electrical engineering all have these basic equations. What are the basic equations in computer science? Or is computer science baseless?
In other words, what's the fundamental intellectual basis of computer science? Well, according to KV, it's data structures!
If there were any set of basics that I wanted to hammer into software…
jstemwedel | March 30, 2010That post about how hard it is to clean up the scientific literature has spawned an interesting conversation in the comments. Perhaps predictably, the big points of contention seem to be how big a problem a few fraudulent papers in the literature really are (given the self-correcting nature of science and all that), and whether there larger (and mistaken) conclusions people might be drawing about science on the basis of a small fraction of the literature.
I will note just in passing that we do not have reliable numbers on what percentage of the papers published in the scientific literature…

Science is supposed to be a project centered on building a body of reliable knowledge about the universe and how various pieces of it work. This means that the researchers contributing to this body of knowledge -- for example, by submitting manuscripts to peer reviewed scientific journals -- are supposed to be honest and accurate in what they report. They are not supposed to make up their data, or adjust it to fit the conclusion they were hoping the data would support. Without this commitment, science turns into creative writing with more graphs and less character development.
Because the…
eklemetti | March 25, 2010Alan Boyle, Science Editor for MSNBC.com, was kind enough to answer questions about science in the mainstream media after the fallout of the coverage of the Chilean earthquake.
Alan Boyle, science editor for MSNBC.com
Alan has been with MSNBC.com since 1996, covering science and technology. He has his own blog on space called the Cosmic Log. He's also won quite the array of awards including from the National Academies, the American Association for the Advancement of Science, the National Association of Science Writers, the Society of Professional Journalists, the Space Frontier Foundation,…
rallain | March 25, 2010Think Thank Thunk is a relatively new blog from Shawn Cornally, a high school math and science teacher. I have found his posts to be quite entertaining. In Shawn's latest post, he talks about grades. You know I like to talk about grades. Shawn puts teacher into two groups in regards to their ideas about grades:
"
Grades should reflect a student's progress with course material. Where an A+ indicates mastery.
Grades should be an amalgam of student's knowledge, behavior, and anything else the teacher wants to control.
"
I was in the middle of posting a comment to this post, but it was…

This post is the third in a series on the origin and history of HeLa S3 cells. The first post details how I came about to ask this question when launching my independent research laboratory. The second post details the life and careers of the legendary physician-scientist pioneer, Dr. Florence Rena Sabin.
Today, we take up a discussion where we will finally learn the origin of HeLa S3 cells, complete with original literature citations.
A recap
We left our previous discussion with the final and still-productive years of Dr. Florence Rena Sabin. After graduating from Johns Hopkins Medical…
oracknows | March 16, 2010I realize that I've said many times before that there is no such thing as "alternative" medicine. There is medicine that has been shown to work through science, medicine that has not yet been shown to work, and medicine that has been shown not to work. "Alternative" medicine that is shown to work through science ceases to be "alternative" and becomes simply medicine.
There are times when I think I might need to change that opinion.
Well, not exactly. However, promoters of various forms of alternative medicine, stymied when they try to show that their woo works through science, seem to think…

While we regularly post lengthy discussions on Obesity Panacea, there are many research updates, news stories, videos, etc. in the field of obesity, physical activity and nutrition that we come across on a daily basis that never grace the pages of the blog. Most of these mini-stories we share with our followers on Twitter, and we encourage those of you with active Twitter accounts to communicate with us there to get real-time updates of all the stuff we are discussing (Follow Peter and/or Follow Travis). For those of you who shy away from Twitter, enjoy below the best mini-stories that we…
neurophilosophy | March 10, 2010ALZHEIMER'S Disease is the most common form of dementia, affecting an estimated 30 million people worldwide. The cause of the condition is unknown, but the prime suspect is amyloid-beta (Aβ), a 42-amino acid peptide which accumulates within neurons to form insoluble structures called senile plaques that are thought to be toxic. Aβ is synthesized in all neurons; it is associated with the cell membrane, and is thought to be involved in cell-to-cell signalling, but its exact role has eluded researchers.
A new study published in the open access journal PLoS One now shows that Aβ is a potent…

Jonah Lehrer's story on "Depression's Upside" has created quite a kerfuffle. The idea he explores â that depression creates an analytic, ruminative focus that generates useful insight â sits badly with quite a few people. It's not a brand-new idea, by any means; as Jonah notes, it goes back at least to Aristotle. But Jonah (who â disclosure department â is a friend; plus I write for the Times Magazine, where the piece was published) has stirred the pot with an update drawing from (among other things) a very long review paper published last year by psychiatric researchers Paul Andrews and…
clock | March 8, 2010As you may know, I love the Journal of Science Communication. It publishes some very interesting and useful scholarly articles on a wide array of issues pertaining to the communication, education and publishing of science. I wish more science bloggers (and non-blogging scientists) read it and blogged about their articles. Unfortunately, human nature being as it is, most of the excellent papers go by un-noticed by the blogosphere, while an occasional sub-standard paper gets some play - it is so much easier to critique than to analyze or even praise.
One such paper is now making the rounds - it…

razib | March 2, 2010Last spring I posted a review of Scitable at Nature. Since then Scitable seems to have expanded a bit, and I have given some more thought on its possible role in the ecology of the infosphere. Back in 2004 when I began to use Wikipedia regularly I was very impressed by the quality of the technical articles, but now that it's 2010 I have to say that far too often the Wikipedia entries are a bit thin in some domains. I suspect that my own expectations have started to outrun what is possible with Wikipedia, and probably I notice the "lack" because I've stopped going to Google as the first option…
drorzel | February 25, 2010One of the weird-but-cool things about being C-list famous on the Internet is that some publishers now send me unsolicited review copies of forthcoming books about science. These aren't always the books I would really like to get free copies of, but, hey, free books.
Among the books I've received in the last year or so is Anil Ananthaswamy's The Edge of Physics, which I got as an ARC several months ago-- I read a bunch of it in Houston at the Sigma Xi meeting back in November-- but I just realized that it's due out next Tuesday, and I really ought to post a review of it.
As you can guess from…
oracknows | February 22, 2010Sometimes politicians actually get it right.
I know, I know, it makes me choke on my words to admit it, but sometimes politicians can actually get science right. I'm referring to something that happened in the U.K., yesterday, when the Science and Technology Select Committee delivered its verdict on homeopathy. Indeed, the Committee has gone so far as to call for the complete withdrawal of NHS funding and official licensing for homeopathy. The report is called Evidence Check 2: Homeopathy, and I'll cut to the chase. This is what the report concluded:
By providing homeopathy on the NHS and…
cortex | February 22, 2010In my recent WSJ article on age and creativity, I didn't have space to discuss the fascinating research of David Galenson, an economist at the University of Chicago who brings together a vast array of evidence to better understand the nature of creative production over time. Galenson divides creators into two distinct categories: conceptual innovators and experimental innovators. In general, conceptual innovators make sudden and radical breakthroughs by formulating new ideas, often at an early age. In contrast, experimental innovators work by trial and error, and typically require decades of…
cortex | February 19, 2010I've got a new article in the Wall Street Journal on the complex relationship between age and scientific creativity:
When James Watson was 24 years old, he spent more time thinking about women than work, according to his memoir "Genes, Girls and Gamow." His hair was unkempt and his letters home were full of references to "wine-soaked lunches." But when Mr. Watson wasn't chasing after girls, he was hard at work in his Cambridge lab, trying to puzzle out the structure of DNA. In 1953, when Mr. Watson was only 25, he co-wrote one of the most important scientific papers of all time.
Scientific…
jrosenhouse | February 18, 2010Via Jerry Coyne I came across this essay regarding the interpretation of Genesis. (Click here for Part One of the essay.)
The article is by Kenton Sparks, a professor of Biblical Studies at Eastern University. His argument will be entirely familiar to connoisseurs of this issue. The Bible, you see, was never intended to teach us science. Augustine and Calvin understood that if the Bible conflicts with well-established scientific truths, then it is our understanding of scripture that must yield. Modern creationists err in treating Genesis like a science textbook, and would do better to…
clock | February 17, 2010Continuing with the tradition from last two years, I will occasionally post interviews with some of the participants of the ScienceOnline2010 conference that was held in the Research Triangle Park, NC back in January. See all the interviews in this series here. You can check out previous years' interviews as well: 2008 and 2009.
Today, I asked Marie-Claire Shanahan who teaches Science Education at the University of Alberta, Edmonton to answer a few questions.
Welcome to A Blog Around The Clock. Would you, please, tell my readers a little bit more about yourself? Where are you coming from (…
