R-Type Channels - A New Type Of Calcium Channels Controlling Signal Transduction Between Neurons In The Brain

Researchers found that R-type channels control transmitter release in presynaptic terminals, contributing to fine-tuning synaptic activity. These high-voltage-activated channels are resistant to known blockers and have been identified through simultaneous recordings of Ca2+ influx and EPSC evoked by a single action potential.

Smart Concrete May Mean Less Road Closures

Researchers at U of T's Institute for Aerospace Studies have developed a smart structure on the Leslie Street bridge, lining columns with fibre-optic sensors and wrapping them with lightweight synthetic materials. The sensors precisely measure corrosion and hold the structure together, reducing road maintenance and closures.
