IGGY and Litro Young Writers’ Prize
2015/2016
The Royal Institute has many simulation games
to show how changes affect the ecosystem.
IGGY is delighted to announce that for the
sixth year running, IGGY will partner with
Litro to host the iGGY and Litro Young Writers’ Prize 2015/2016.
This competition is open to creative 13-18
year olds all over the world. The theme this
year is Movement. The entry needs to be
submitted before 8th of February 2016.
How do you know when it's time to
wake up or go to sleep? More powerful
than any alarm are your circadian
rhythms. In the animation below you
can follow how circadian rhythms work
and what controls them; inspired by the
TeenSleep project being carried out at
the University to look at how later start
times at school might affect achievement.

If you're a plant-eating insect, every day is an allyou-can-eat buffet. However, plants aren't always happy about being eaten and will put up a
fight. Plants have developed different defence
mechanisms to protect them against insect
attacks. Some have spiky leaves, some are
sticky, some are poisonous and some release
chemicals which attract insect predators.
It began with a dream...

Key questions:
Can you think of other leaders who have inspired 'movement' or change? Who is your
most inspirational Nobel Peace Prize winner?
The civil rights movement started in America in
1954. The movement was designed to highlight
the inequalities faced by Afro-Americans living in
the USA at the time. Martin Luther King became
a figurehead for the movement and eventually
was given the Nobel Peace Prize in 1964 for his
contributions.
Hippopotamian Logic
DNA can provide the key to solving crimes. The
police often discover evidence from the scene of
a crime, which will then be passed on to a team
of forensic scientists to analyse. Here's where
you come in! Try playing the part of a forensic
scientist performing a DNA profile. See if you
can correctly test the sample taken from a crime, I won’t eat my hat.
and help support the police in their identification If hippos don’t eat acorns, then oak trees will
grow in Africa.
If oak trees don’t grow in Africa, then squirrels hibernate in winter.
If hippos eat acorns and squirrels hibernate
in winter, then I’ll eat my hat.
Therefore – what?
of the guilty suspect.
It's tough out there in the natural world. In their
fight for survival, many plants produce poisons
to keep predators at bay. Many drugs used in
medicine today are made from poisonous plants,
as are a few guilty pleasures, such as coffee. Can
you match each drug with its plant of origin?

Solution
Therefore oak trees grow in Africa.
Why? Suppose, on the contrary, that oak
trees don’t grow in Africa. Then squirrels
hibernate in the winter, and hippos eat

What are circadian rhythms?
The word ‘circadian’ comes from the
Latin ‘circa’ meaning ‘around’ and ‘diēs’,
meaning ‘day’. Our circadian rhythms
are biological processes that follow a
(roughly) 24-hour cycle. Throughout the
day our alertness levels will wax and
wane, as will our temperature, bloodpressure, appetite and hormone production. These fluctuations are examples of
circadian processes. The most obvious
circadian process is the sleep-wake cycle.
How does our body know when it’s time
to sleep?
Humans detect light through the eye.
Light enters the eye and is focused onto
the retina at the back of eye. The retina
contains photoreceptive cells that detect
light and send this information to the
brain, via the optic nerve. The most obvious outcome of this process is the ability to form images; to see. Imageforming vision depends upon rod and
cone photoreceptors, which are critical
for low light vision and bright light colour vision, respectively. However, it was
discovered in 1999 that the circadian
system of animals lacking rods and
cones could still respond to light. This
led to the discovery of a new class of
photoreceptive cells: the photo-sensitive
retinal ganglion cells (pRGCs), which
express the light sensitive pigment melanopsin. These pigments undergo a
chemical reaction when they absorb
light, which causes the ganglion nerve
cells to fire signals to the brain.
