Check this out, from the BBC. Dr Michael Mosley has himself infected with various parasites, including this big tapeworm, for our edutainment.
Full episode on BB iPlayer (limited time): Here.
Here’s a leech, for fun.
This week was the first episode of Dara O’Briain’s Science Club from the BBC. The theme: Genetics. Here’s their introductory animated clip, which gives a neat condensed history of sex, genes and DNA:
I’m looking forward to seeing the series!
Professor Bruce Hood explores the human brain in this series of lectures from the Royal Institution in London. The trailer is below and in time all the lectures should appear on the RI Channel Website here (Vimeo channel here).
The theme of the 2010 Lecture series by Mark Miodownik was “Size Matters”, again relevant to the IB Biology course and available to watch in full from the RI Channel website.
He also has a radio show/ podcast called The Infinite Monkey Cage, hosted with Brian Cox on the BBC. In this episode, Six Degrees of Separation, they discuss the connections of humans with Stephen Fry, Simon Singh and Alex Krotoski.
Here’s a neat little clip from Nature Video, with natty soundtrack, highlighting 135 space missions of the NASA shuttle programme. If you have access to BBC iPlayer, you can see a very insightful documentary on the final shuttle flight here. Visit NASA’s shuttle resources to find out more about the shuttle programme, its successes and dramatic episodes, as well as what is next for NASA.
I heard about this series on BBC 4 when listening to the Guardian Science Weekly podcast recently. They had the presenter and physicist, Jim Al-Khalili, on the show talking about some of the great discoveries and advances made in the Islamic world between the 8th and 14th Centuries.
Think about it this way – if it has an ‘al’ at the beginning, there’s a fair bet that it was discovered, invented or pushed forward in the Islamic world: algebra, algorithms, alkali, alcohol…
Alhazen (Ibn al-Haythem) is considered one of the founders of the scientific method which we still use today – a good scientist formulates a hypothesis and devises a method to prove it wrong. In this way, we know if a scientific idea stands up to testing. If not, we need to revise the hypothesis and test again.
You can see the official BBC page for the programme here, but the video may no longer be available to download. Alternatively, pick up the episodes (broken into parts), from YouTube:
1: The Language of Science
2: The Empire of Reason
3: The Power of Doubt

“There is no evidence because it would be hard to prove…” Aduh.
BadScience hero Ben Goldacre and Jeremy Paxman take on Baroness Greenfield, The Daily Mail (always a good target) and Aric Sigman in this interview from Newsnight. For a bit of background this is all a response to this story from the Daily Mail: http://www.dailymail.co.uk/health/article-1149207/How-using-Facebook-raise-risk-cancer.html
If you’re in my class, the page you need to comment on is here.
The Daily Mail reports Sigman is claiming (without any real evidence) that time on the computer takes you away from real people. This makes you isolated and lonely and means you are not producing the right hormones and your genes will act up – potentially leading to cancer, immune problems and impaired mental function. That’s a far reach for a newspaper article to be making, but these kind of shock headlines sell papers, or get more traffic on their website.
In this debate we see the importance of peer-reviewed research before making public claims. We see that correlation does not necessarily imply causality and we see that poor reporting of sensitive issues can lead to gross misunderstandings. If we remember, the Daily Mail was central in the reporting of the MMR vaccine scare.
When you watch this interview and read the article, can you think of responses to these questions?
– Are there parts of Sigman and Greenfield’s claims that might sound plausible?
– What kind of evidence would you want to see to support these claims?
– What is the significance of Goldacre’s comment “… you can make anything look dangerous if you are selective in which evidence you quote” ?
– Sigman makes a comment “The paper weas supposed to be a one-sided provocative feature article for The Biologist to make people think more carefully about where society is going.” How does he feel about the media attention that his words have attracted outside this publication?
– Central to Sigman’s claims were that internet use increases social isolation. He had no peer-reviewed work after 1998 to support this, yet Goldacre pointed out all these references that suggest otherwise.
– Sigman tries to re-state ‘social networking’ as a phrase meant for real-life interactions between people rather than internet-based interactions. How has his interpretation of the term led to confusion in the wider public? Who do you think is responsible for this confusion and how could it be rectified?
– Sigman tries to distance himself from the headlines and the conjectures of Greenfield and returns to his concern that internet use is having a direct and negative impact ont the lives of children. Take this opportunity to discuss the benefits and potential negative impacts of the internet with regard to childhood use.
– Goldacre makes a comment that it woudl be bad for research to prioritse what research is done based on the headlines in the newspapers. Do you agree/ disagree? Why?
– How do you think the precautionary principle might relate to the decisions parents make based on this issue?
How would you like to see this story develop? What further research would convince you of the harms or otherwise this debate?
