The growing menace of antibiotic resistance has been the subject of increasing press attention in recent years. In this clip from the BBC’s medical magazine show Trust Me I’m A Doctor surgeon Gabriel Weston investigates a potential alternative to antibiotics, the use of bacteriophage in an approach known as Phage Therapy. This apparently novel approach has actually been the subject of extensive research over many decades in the former Soviet Union, especially in the Republic of Georgia. Patients whose diseases are proving resistance to more traditional Western treatments based on antibiotics are now travelling to the Eliava Institute in Tbilisi to try this alternative.

In this 4 minute clip from Inside Science, presenter Adam Rutherford interviews Professor Paul Sharpe from King’s College London about the use of stem cells to regrow damaged dentine. Sharpe and his team have used Tideglusib, a drug originally as a treatment for Alzheimer’s disease in order to regrow teeth.
Below a thin layer of enamel, there is a thicker layer of another material called dentine. Although enamel cannot be regrown, it is possible to stimulate immature stem cells to become dentine, offering a natural alternative to metal or porcelain fillings.
After the rotten area of the tooth has been drilled out, Sharpe and his team insert a swab impregnated with the drug Tideglusib into the hole. The drug stimulates the Wnt signalling pathway, activating more stem cells. So far the work has been done in mice. In doing so they are taking advantage of the fact that the drug has previously been put through extensive safety trials when being considered as a treatment for neurological diseases such as Alzheimer’s. Sharpe hopes this might speed the process to clinical trials for this novel dental application, though even then clinical trials are unlikely to start before 2018 at the earliest.
For further information see this press release from the King’s College website.
New “go for gold” advice from the Food Standards Agency is warning people not to overcook foods such as roast potatoes, chips and toast, as it increases their risk of cancer. The story was widely reported in the press on 23rd January 2017 (e.g. Browned toast and potatoes are ‘potential cancer risk’, say food scientists).
Useful broadcast media coverage includes:
BBC News at One: Is burnt toast a cancer risk?
(2 mins 40)

Today (BBC Radio 4): Can overdone toast be a cancer risk?
(4 mins 30)
Concern focuses on acrylamide, a chemical that is naturally produced when starchy foods (particularly those rich the amino acid asparagine, such as potatoes and cereals) are cooked at high temperatures (see Mottram et al and Stadler et al for underlying science, which actually dates from 2002).

Watson and Crick discuss whether to tell Maurice Wilkins and Rosalind Franklin about their research
(originally broadcast 1987 on BBC2)
In the late 1980s, Horizon, the BBC’s flagship science series, took the unusual step of producing a feature length retelling of the events of 1951-52 leading to James Watson and Francis Crick solving the structure of DNA.
Inspired by Watson’s memoir The Double Helix, and with a screenplay by William Nicholson (who later went on to write the script for Gladiator), the production starred Jeff Goldblum as Watson, Tim Pigott-Smith as Crick and Juliet Stevenson as Rosalind Franklin.
A colleague recommends that students watch this on their own as a “flipped teaching” exercise prior to more academic sessions on DNA structure.
The film is known in the USA as “The race for the double helix” and is listed on IMDB under that name. The most recent transmission of this programme pre-dates Box of Broadcasts, and this copy is uploaded from a VHS copy. In consequence, the quality is sub-optimal, but clear enough.

This short clip from the English-speaking Japanese channel announces the introduction of a regulatory body for genetic testing in Japan. Establishment of The Council for Protection of Individual Genetic Information (CPIGI) was prompted by a number of concerns. For example, companies offering tests Direct-to Consumer (DTC) genetic testing have not necessarily given sufficient diligence to the security of private genetic information, or to the interpretation of the results. This is especially true for diseases that result from the interaction of multiple gene products as well as the influence of environment on expression of those genes (so called GxE interactions). The clips cites diabetes and Alzheimer’s disease as examples where a correlation with a particular allele at a particular gene may be hard to quantify.
The CPIGI, which launched in Oct 2015 (after the initial broadcast of this episode) is an umbrella group for 25 companies and offers a checklist of over 200 items intended to enhance trust between genetic test providers and clients. This includes the importance of genetic counselling. The launch of CPIGI has been controversial (e.g. see here), especially regarding the lack of consultation.
See this post for details of clips from Newsnight and BBC Breakfast in 2014, regarding the UK launch of DTC genetic service 23andMe.

The BBC’s rural affairs programme Countryfile (first broadcast on 9th October 2016) looked at ongoing issues with TB infection cattle populations. The topic was covered in two sections. The first focuses on the current tests for TB infection. The second looks more closely at the science being used to develop new tests and better vaccines against TB. Continue reading

Dr Xand van Tulleken hosts this satirical show (30 mins) taking a look back at some health news from 2016. He elaborates on potentially misleading news headlines and explains the research behind them. Tulleken is keen to push the message that the unsubstantiated claims of pseudo-science detract from the credibility of real science that could actually help people. The humorously presented topics range from scaremongering health claims and celebrity endorsed miracle cures, to squat toilets and cigarette packaging; he even uses cheese as a visual aid to illustrate the factors behind the junior doctors’ strikes.

In this special episode of the BBC radio programme All in the mind (28 mins), host Claudia Hammond discusses the basis of memory formation with three leading researchers Tim Bliss, Graham Collingridge and Richard Morris who have been major players in developing our understanding of memory.
Tim Bliss draws attention to Donald Hebb’s pivotal book The Organization of Behavior and the aphorism “Cells that fire together, wire together”. Graham Collingridge then introduces the notion of long-term potentiation (LTP) as the molecular basis of memory, and particularly the role played by NMDA receptors in learning and AMPA receptors in memory. Errors in the functioning of any of hundreds of proteins can have detrimental impact on memory. Under-activation of LTP can be a contributory factor to schizophrenia. Continue reading
Dear Biology on the Box visitor,
Welcome to our site – welcome back if you’ve been here before. We aim to provide recommendations of television and radio resources which have been broadcast in the UK as a means to promote engagement in bioscience teaching.
In doing so, we make particular use of Box of Broadcasts, a collection of copyright-cleared recordings for use in education. At present a major upgrade to BoB is underway.
As a consequence, although the core information on our site remains valid, the specific links to clips from the programme are all currently broken. We apologise that this constrains usage of our resources. This is a temporary issue, but it is one beyond the control of the Biology on the Box team, and once the links are restored we will be back underway at full steam.
UPDATE (26th September): I am pleased to report that most of the links to clips within Box of Broadcasts have now been restored (though you will still need to be within a subscribing institution to reap the full benefit of this service). If you find any links that are still broken, please let us know. Thank you, and happy viewing.
In this three minute clip, Fergus Walsh reports on a trial being conducted at Guy’s and St Thomas’ NHS Foundation Trust (London). The research, led by Prof Mark Peakman, is using a combination of protein fragments (MultiPepT1De) to try and trigger a “protective” immune response, rather than the inappropriate antibody production against islet cells that underlies Type 1 diabetes.
This link includes a video by Prof Peakman introducing the biochemistry of Type I diabetes and the basis of their research (5 mins). See also this article by Peakman on the principles behind the new approach.
