Reflections of research: The videos
This year we have added to our science
imagery competition with a video competition!
Check out the videos below -
and let
us know what you think on our Facebook wall!
Don't forget to check out the photo competition and vote in our poll for your
favourite photo!
The Winner...
Blood streams from the heart
This is a
simulation of virtual particles in the blood moving through a
person’s heart, based on MRI scans of a man’s chest. The
blue arrows show blood flowing into the
right side of the heart, and being pumped out towards the
lungs. The red and yellow arrows show blood in the left
side, being pumped out into the aorta, the body’s main
artery.
By Dr Michael Markl, University of Freiburg, & Dr Philip
Kilner, Imperial College, London.
Runners up...
Depth perception
Powerful electron microscopes let scientists see the
tiniest structures in the body. This video shows
the special connections between heart muscle cells
that allow them to communicate with each other with chemicals,
electrical signals and by pulling on each other. These
interactions are vital for making the heart pump
properly.
Dr Pauline Bennett & Dr Amanda Wilson, King’s College,
London
Emboli - Small but deadly
Emboli are fragments
that break off of diseased blood vessels and drift through the
bloodstream. If they get lodged in the brain, they can
block the blood supply and cause a stroke. This video
shows emboli moving through a model of the arteries in the brain.
It was recorded at 300 frames per second and has
been slowed down to one tenth of normal speed – one ‘heart
beat’ every 10 seconds.
By Dr Emma Chung, University of Leicester
