...neurotoxin, which cuts through the protein strands connecting the two, much like a fish would cut through a fishing line. The bead's separation causes the cantilever to vibrate, announcing the neurotoxin's presence. While effective, the process is not yet ready for practical application.

CHAMPAIGN, Ill. -- From within the rich fabric of connecting tissue between cells, researchers of four institutions, led by the University of Illinois at Urbana-Champaign, have identified the action of anastellin, a natural agent that is showing promise blocking metastasis of cancer cells and enhancing wound h...Research grants program closing

People have been studying these patterns with fossil evidence for some time, but there is not much of a fossil record for lizards and many other terrestrial groups.......ls have so far defeated these efforts. The channel connecting the two should soon dry up anyway, preserving the Small Aral Sea at least.

Most notably, the group developed the first robotic device whose movements are controlled by a cultured neural network capable o...Human stem cells improve movement in paralyzed rats

"Simply keeping a neuron alive can't improve physical abilities if it's not connected to other neurons. It must be part of a circuit.

...so appears to be the lynchpin of a protein complex connecting components inside and outside of cells. The UI study showed that loss of dystroglycan disrupts this complex in Schwann cells and leads to neuropathy.

...hall applied piconewton-scale forces to a junction connecting P-selectin and PSGL-1 molecules. Despite the difficulty of measuring such small forces, he was able to demonstrate that increasing the force extends the lifetime of the bonds under certain conditions. "In one range, when we are increasing the force,...Georgia Tech researchers use lab cultures to control robotic device
... from the National Institutes of Health, Potter is connecting laboratory cultures containing living neurons to computers in order to create a simulated animal, which he describes as a "neurally-controlled animat."
