Mayor Rob Ford seems to favour tunneling transit underground in Toronto. But a growing number of international cities, including some in Canada, are casting their eyes to the sky at an unconventional mode that’s cheaper, cleaner and quicker to build than subways and light rail. read more

The international team of researchers that has been smashing high-energy protons together inside the Large Hadron Collider (LHC) to re-create the conditions at the time of the Big Bang announced new evidence today pointing to an observation of the Higgs boson. The Higgs boson is a hypothetical massive elementary particle that is predicted to exist [...]

U of T discovery sheds light on massive star cluster - Dec 8, 2011 - 12:57 pm

Largest grouping ever observed in our galaxy

Three astronomers at the University of Toronto have found the most numerous batch of young,  supermassive stars yet observed in our galaxy: hundreds of thousands of stars, including several  hundreds of the most massive kind --blue stars dozens of times heavier than our Sun. The light  these newborn stars emit is so intense it has pushed out and heated the gas that gave them birth,  carving out a glowing hollow shell about a hundred light-years across.

Three University of Toronto astronomers have discovered the largest group of young stars ever observed in our galaxy, which they hope will bring science one step closer to understanding the evolution of stars. read more

Researchers often work with a narrow range of compounds when making organic electronics, such as solar panels, light emitting diodes and transistors. Professor Tim Bender and Ph.D. Candidate Graham Morse of University of Toronto’s Department of Chemical Engineering and Applied Chemistry have uncovered compounds that exhibit unique and novel electro-chemical properties. “Organic solar cell need [...]
