LONDON MEETING
24-25 MARCH 2006
WWW.NEXTGENERATIONSCIENCE.ORG
From Molecules to Behaviour
University College London, the ‘Godless place on Gower Street’, was the setting for
the second meeting of teachers and students from the Rotterdam-London Next
Generation Science Programme. This was a fitting location for a meeting focused not
just upon excellence in science, but also upon building links between people of
different backgrounds and cultures. UCL itself was originally established to provide
an egalitarian alternative to Oxford and Cambridge, and was the first English
university to be open to all, regardless of race, or political or religious belief. Also
appropriate was the involvement of the EU Network of Excellence ‘Cells into Organs’.
The theme of the meeting ‘From Molecules to Behaviour’ is intricately entwined with
many of the research themes of ‘Cells into Organs’, and the expertise of several
network members was used during the meeting.
Professor Claudio Stern from the
Department of Anatomy and
Developmental Biology, opened the
meeting by welcoming the students and
teachers to UCL. He spoke of the
colourful history of the university, and
the current opportunities for students in
his department, where a wide variety of
courses, from history of medicine to
neuroscience, can be followed.

‘He who thinks and thinks for
himself will always have a
claim to thanks; it is no matter
whether it be right or wrong,
so as it be explicit. If it is right,
it will serve as a guide to direct;
if wrong, as a beacon to warn.’
– Jeremy Bentham, ‘Spiritual
Father’ of UCL.
Professor Stern was followed by the
writer and distinguished Developmental Biologist, Lewis Wolpert, who talked,
sometimes controversially, about the nature of science itself. The main thread of his
argument was that despite the ‘long tradition that science is evil’, reliable science has
zero ethical content, and so there should be no areas that scientists cannot investigate.
Science is universal, and culture-free, where the individual is irrelevant as the facts
are always the same no matter who discovers them. Professor Wolpert argued that
ethics comes into play only when it comes to technology, the application of knowledge,
not with science itself, which is more the pursuit of knowledge.
‘There is no such thing as ‘off-limits’ in science’
– Professor Lewis Wolpert
Professor Wolpert’s talk stimulated plenty of questions from the audience, such as
‘Does there need to be a conflict between religion and science?’. There was also a
question about the idea of ‘reliable’ science, particularly after the many revelations
of unreliable science in the media recently, and Professor Wolpert made it clear that
although he believes that scientific knowledge is value-free, how science is performed
can indeed raise ethical questions.

From Genes to Behaviour -Asymmetry in the Brain
Imagine you are shaking somebody’s hand - which hand do you use? It will probably
be the right one (even if you are left-handed) and this is just one example of
asymmetric behaviour which, though influenced by social and environmental factors,
often has an underlying biological cause. In his lecture, Professor Steve Wilson used
examples of asymmetric behaviour to give us our first glimpse of how molecules, such
as the protein products of functioning
genes, can influence behaviour. At the

around the topic.
Q
A
‘Could you engineer a creature with
both sides of the brain dealing with
logic; a double left-sided brain?’
Asymmetries are widespread throughout the animal kingdom, and were probably
already present half a billion years ago, as shown by fossils of animals which were
attacked more often on one side than on the other. Frogs and chickens show obvious
asymmetries in the way they obtain their food, as do certain fish which develop their
mouth on one side of their body.
Humans also exhibit asymmetry in

generally deals with logic and
language. Professor Wilson discussed
some of his research in zebrafish which throws light on how these differences arise. A
region of the brain called the forebrain shows asymmetry in most vertebrates, and in
zebrafish this asymmetry is easily visualised. This makes it possible to investigate
what happens when genes are disrupted and Professor Wilson demonstrated how,
when certain genes are lost, the asymmetry of the brain is randomized. In cases
where the brain asymmetry is reversed compared to normal, some behavioural
patterns (such as which eye a fish uses when it looks at itself in the mirror) are also
reversed, showing how genes can indeed affect behaviour.

Lab Demonstrations
When it came to the laboratory demonstrations, the staff and researchers at UCL
excelled themselves in both the quality and the organisation of the demonstrations.
Thanks to the generosity of the demonstrators, both the students and the teachers
were able to participate, and for the teachers this was particularly welcome as it
allows them to bring what they have seen back into their classrooms.
The demonstrations covered many aspects of the theme, from observations at the
molecular level, through early developmental events, to complex neurological and
behavioural processes. Participants were able to use electron and confocal
microscopes, manipulate developing embryos from various organisms, learn about
how the brain processes spatial memory and pain, and during the demonstration on
biological clocks they were encouraged to start their own investigations by recording
their sleep patterns.
Lab demonstrations led by researchers from the Department of
Anatomy and Developmental Biology, UCL.

Embryonic Research and Cloning Workshop
During this workshop the students were separated into two groups of 15, and they
then discussed various aspects of embryonic research and cloning with either Sammy
Lee or Arlene Klotzko. After about an hour the groups got together and had a
feedback session about their discussions. The group led by Sammy Lee focused on
the technology of human cloning and amongst other things addressed the question ‘Is
a clone true life?’. Arlene Klotzko talked about the social, ethical and legal
implications of human cloning, including whether we are now on a ‘slippery slope’
which could lead to the compromising of moral principles.
‘Is this progress, or are we becoming more morally corrupt?’
– NGS student
These sessions brought out some interesting points, including the coining of the term
‘frone’ – your headless clone in the freezer, which you keep for spare parts, and the
idea that females are stronger than males, at least in embryonic terms. At the end of
the session, when the reasons for human cloning, and the implications of the
technology were discussed, the workshop leaders praised both the level of
understanding and the moral stance of the students.

Poster Workshops
During the poster workshops the students were given a taste of how scientific
research is often presented. They were split into small groups and spent some time
with the workshop leader discussing a particular experimental result, which they were
encouraged to interpret. Then, in quite a short space of time, the students had to
produce a poster explaining the research. During an informal poster session they
had to stand by their posters and explain to the other participants about ‘their’
research. The resulting posters were excellent and the ability of the students to
explain often complex experiments and scientific theories was very impressive. This
exercise gave them a taste of actual research and how experiments are designed
and interpreted, and introduced them to the world of scientific conferences, where
poster sessions like this are used routinely by researchers to present their results.

The Sally-Ann test
Autism and Our Social Brain
- Sally has a marble in her basket.
- When Sally leaves the room, Ann puts the
marble into her box without Sally seeing.
- When Sally comes back into the room,
where will she look for the marble – in her
basket, or in Ann’s box?
Many animals exhibit social behaviour, such as grooming and looking after young,
but there are some social behaviours which seem to be particular to humans, such as
taking another’s perspective and being aware of one’s own emotions. One characteristic important for these social behaviours is the ability to ‘mentalise’; to think
about thoughts and attribute mental states to others, and it is this ability which is
often impaired in people with autism. Professor Uta Frith discussed this in her lecture,
and explained a little about the tests for mentalising ability and which areas of the
brain are involved with this process. The audience was fascinated by her account of
how we distinguish between our own thoughts and other’s, and how we can ascribe
complex meaning and behaviour to simple objects moving in a particular way. The
talk prompted many questions about autism, social behaviour and mentalising,
including a searching question from one student about the ability of animals, in
particular pets, to be aware of the moods and emotions of others. Professor Frith
answered that this area needs more research and encouraged the student to ‘Go
ahead and study it!’.
Although most children over the age of 5
correctly say that Sally would look for the
marble in her basket, children with autism
often point to where the marble actually is,
as they cannot distinguish between their
own thoughts, and Sally’s.
Professor Uta Frith, Institute of Cognitive Neuroscience, UCL
Epigenetics
X-inactivation
In female mammals, one X
chromosome is randomly inactivated
in every cell. This is why calico cats
have patches of black and orange fur,
depending on which X chromosome
has been inactivated.
Even though identical twins have exactly the same genetic material, they still exhibit
differences; for example where one twin is diabetic and the other is not. This can be
due to epigenetic differences and Professor Frank Grosveld explained in his talk
about the emerging field of epigenetics; the study of reversible heritable changes in
gene function that occur without alterations to the DNA sequence. One example of
this is X-inactivation, and another is imprinting, where for certain genes only the copy
inherited from the father is used and for others only the maternal copy is used. In
general, paternal imprinted genes promote growth and maternal ones inhibit
growth, perhaps in the latter case to protect the mother. Professor Grosveld went on
to explain how epigenetics can be important in medicine, for example in cancer
diagnostics. This discussion was taken up by the audience, when diseases on the X
chromosome were mentioned, where females may not become as sick as men because
half of their X chromosomes have been randomly inactivated.

The Adolescent Brain
In the final talk of the meeting, Dr Sarah-Jayne Blakemore talked about something of
immediate interest to her audience; social cognition and the adolescent brain. She
first explained how the brain is hardwired for social interaction, a degree of which
is evident even in newborn babies who prefer to look at faces than other objects,
and who imitate facial expressions in others.
Later, as the brain develops, the speed of

Teacher Workshop 1: Science Learning Approaches
This session introduced the teachers to ‘Learning Skills for Science’, a recently
developed set of resources aimed at enhancing the core skills which are essential for
science learning. This approach was developed by the Weizmann Institute of Science
and has been produced for UK schools by the Gatsby Science Enhancement
Programme in collaboration with the Nuffield Curriculum Centre. The workshop
focused on the area of scientific reading, and a structured approach to reading was
introduced. Although this may seem intuitive, complex tasks such as reading scientific
articles often benefit from deconstruction, to enable more efficient execution.
Angela Hall, Science Learning Centre, Institute of Education
Sally Johnson, Gatsby Science Enhancement Programme
Teacher Workshop 2: NGS - The Way Forward
The second teacher workshop focused on generating concrete plans for the
continuation of the NGS network. Five groups were made, linking together teachers
from one London and one Rotterdam school; these groups were then asked to outline
project proposals which they would like to implement together. The ideas were then
critiqued by other teachers in order to share expertise and identify the strong and
weak points of each proposal.
Junior Science Café series-Trinity and Calvijn
Organised by students in linked London and Rotterdam schools, who will research a
topic, find a speaker and produce a synopsis. Students from partner schools will
send questions for remote participation. Host students to write article for publication
on website.
European science city trip- Trinity and Calvijn
Linked schools meet in a different European city and follow a programme with a
strong scientific focus. Students who organised JSC to be involved.

The Future of NGS
At the end of the meeting, three different contributors to the NGS programme all
summed up in the same way. Professor Claudio Stern from UCL, Quentin Cooper the
radio presenter, and Lloyd Anderson the Director of Science at the British Council, all
focused on the exciting and rewarding aspects of science, and encouraged the
students to consider scientific careers, whether as researchers, ethicists, lawyers or
one of the many other options open to them. Information about some of the degree
programmes that could lead to these careers is available at www.anat.ucl.ac.uk.
Although this was the last scheduled meeting in the Rotterdam-London phase of NGS,
the relationships built continue in the form of joint projects and planned activities,
such as the compilation of the ‘Alternative Guide to Careers in Science’. As Lloyd
Anderson said, ‘The future of NGS depends on the teachers’ and it was encouraging
to learn that during the second teacher workshop some concrete ideas for
continuation had been proposed.
‘Science is a social activity’
– Professor Claudio Stern
NGS will now be taken to different locations during the next phase of the
programme, when schools from the Durham area and the Wageningen area will take
part in a new partnership. They will again be witnessing top-class research, but this
time at the Wageningen University and Research Centre, where the themes will be
‘Food in the modern world’ and ‘Adapting to a changing world’, and then in 2007
when Durham University will host the NGS programme.
‘What do you find interesting and exciting? That
will be what you do
best.’
- Professor Claudio Stern
Feedback and comments from current NGS participants are helping to shape future
meetings, and it is hoped that the individual networks created during the NGS
programme will interact, forming an extended virtual network of students, teachers
and academics to help promote and sustain science and scientific research in our
society.
‘The only truly adventurous thing to do is science’
– Quentin Cooper
