Scientists from the University of Lincoln and Cambridge University are celebrating the approval of a grant from the Wellcome Trust.


Dr Mark Curry (Lincoln) and Dr Sam Hill (Cambridge) submitted a joint proposal in April this year which will look at aquaporins – molecule-sized pores which transfer water through membranes during osmosis (shrinking and swelling).  


The £20,000 grant will allow the doctors a further two years to continue research into osmotic mapping and hopefully provide answers to a century-old debate concerning how osmosis works in pores.


“This funding gives us the opportunity to build on some preliminary work we published in Journal of Membrane Biology earlier this year,” said Dr Curry, senior lecturer and researcher in the university’s Biology Department.


“We hope the results will support a new theory on the way water actually moves through protein channels.


“Osmotic flow rates and what affects them have been a point of discussion for many years.  The new theory - bimodal theory - relates osmotic flows to the shape of the pore.  Our research will look at this in depth and will hopefully give us an insight into how these important molecules work.”


The Wellcome Trust is an independent research-funding charity which aims to improve human and animal health.
