We broadly work on animals, very broadly. So all animals are equal in the lab, but model animals are more equal than others.
Plastic eating worm
Local to long-range search behaviour of a cherry worm
Typical swarming response of a laboratory strain(N2) C.elegans.
Emergence of swarming response of laboratory strain(N2) around a GFP labeled bacterial lawn.
Emergence of swarming response of mutant strain npr-1 around a GFP labeled bacterial lawn.
Accumulation of worms around Na2SO3 containing agar chunk. Na2SO3 can decrease the oxygen is surface liquid.
Oxygen-dependent motility response of individual animals (npr-1)
Sample simulation results
Typical structural patterns formed by the animal at high population density under different oxygen levels. Top images show N2 and bottom images corresponds to npr-1 strain.
Typical structural patterns formed by the animal at low population density under different oxygen levels. Top images show N2 and bottom images corresponds to npr-1 strain.
Dynamics of bacteria around a single worm on a GFP labeled OP50.
Dynamics of bacteria around a single worm moving on the edge of PA14 biofilm.
Early dynamics of growing biofilm(Starting from a single bacterium)
Emergence of active nematics.
The video shows the biofilm formation of chaining strain.
Emergence of active nematics.
Another example video shows the biofilm formation of chaining strain.
The growing edge of a biofilm.
Colony growth of non-chaining bacterial strain.
The biofilm formation in liquid LB broth.
The results of FEM simulation of a droplet-shaped elastic chain with a long straight tail
The results of FEM simulation of multilayered U shaped structure. U shaped initial configuration give rise to more realistic colony morphology.
Asymmetric odor stimulation causes turning.
Asymmetric excitation of AIY causes turning.
Asymmetric inhibition of AIY causes turning.
Symmetric excitation of AIY inhibits reversals.
AIY::ChR2 animal in a fixed light gradient cannot track the gradient direction.
AIY::ChR2 animal in a virtual light gradient tracks the gradient direction through repeated inversions of the gradient.
