Greider discovered telomerase in the winter of 1984, when she was working with a single-cell pond-dwelling organism known as tetrahymena.

Numerical and experimental results show good agreement; for the reference cell and water pond cell, the difference between the numerical and experimental average indoor temperature becomes 0.1 K in both cases.
MSD water was first pumped into a surge pond (Cell 0), which allowed settling of suspended particles, and provided hydraulic head and water storage for the rest of the facility.
Dr. Blackburn addressed this problem by working with a single-cell organism found in pond water known as Tetrahymena.
To answer these questions, the growth, photosynthetic oxygen evolution property, and specific growth rate for microalgal cells in open-pond and 'attached cultivation' systems were studied to determine the dynamics of effective light penetration (dE, depth from the surface where the light intensity is equal to the light compensation point) during cultivation.
Pond snail neuron cell membrane potential was monitored using glass microelectrodes to access the concentration of serotonin [43].
Saouter et al. [54] studied mercury removal from freshwater pond by resting cells of mercury-resistant Aeromonas hydrophila strain KT20 and Pseudomonas aeruginosa PAO1 derivative containing a plasmid carrying mer genes.
Finally, due to their low culture density (0.1% of mass) in ponds and small cell size (1 10 μm) considerable energy, accounting for up to 40% of production costs, may be required to harvest microalgae [ 8, 18].
According to our pilot experiment, from day 0 to day 30, there were non-significant differences among LCPs of algal cells from the outdoor open pond supplied with a non-nitrogen-deficient nutrient solution.
For reference, the average dissolved metal concentration of the anaerobic cell influent (i.e. the surge pond effluent), is also superimposed on each figure.
