One of the most promising technologies for making inexpensive but reasonably efficient solar photovoltaic cells just got much cheaper. Scientists at the University of Toronto have shown that inexpensive nickel can work just as well as gold for one of…
Using your brain waves to control the environment around you, like the lights in your home or even your toaster, is already a reality. One Toronto-based company has developed a system called thought-control computing, and it is exploring a range…
One of the fundamental tenets of quantum mechanics is that measuring a physical system always disturbs it. If the system in question is a message in a series of digital bits encoded in the polarisation of light, this means that…
As the semiconductors that power the chips and lasers responsible for computing information shrink down to the nano-scale, they produce higher levels of electrical resistance and capacitance that ultimately slow performance. In recent years a research team, led by University…
In the midst of a blistering heat wave, most Torontonians aren’t thinking much about frigid temperatures, ice and winter spills. But in a special laboratory at the Toronto Rehabilitation Institute, walking is a perilous — and chilly — experience for…
With so many shale gas reserves available, major energy companies around the world are racing to start drilling. This carries some big environmental risks, but the upside is too great to ignore. Shale gas could one day lower fuel prices,…
