TORONTO, ON – 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.

These findings will be published in the December 20 issue of Astrophysical Journal Letters. For the researchers, the next step is already clear: “By studying these supermassive stars and the shell surrounding them, we hope to learn more about how energy is transmitted in such extreme environments,” says Mubdi Rahman, a PhD candidate in the Department of Astronomy & Astrophysics at the University of Toronto, who led the work with his supervisors, Professors Dae-Sik Moon and Christopher Matzner.

U of T leading centre for study of global Christianity

A century ago, 80 per cent of the world’s Christians lived in Europe and North America; today, nearly 70 per cent live in Africa, Asia, and Latin America, making Christianity a predominantly non-Western religion.

A critical mass of scholars who are looking into the implications of this shift has made the University of Toronto a leading centre for the study of global Christianity.

Christianity today has more than 2.2 billion adherents worldwide. The majority are overwhelmingly poor, displaced from rural villages into overcrowded cities in search of work, and adhere strictly to the word of Scripture, which can command their loyalty far more than state or society. (more…)

Craig Mundie, Microsoft’s chief research and strategy officer, brought news of Microsoft’s plans to merge the physical world with the digital word during an Oct. 6 lecture at the University of Toronto.

“The computer is being endowed with more and more human sensing-like capability,” said Mundie. “We think this will be the predominant way people will use computers in the future.” (more…)

*Former prime minister’s speech honours Alan Gotlieb, former ambassador to U.S.*

Former prime minister Brian Mulroney, the man entrepreneur Peter Munk described as “one of our greatest statesmen,” attributed much of his success – and Canada’s under his leadership – to the personal relationships he and his ambassador cultivated with leaders south of the border.

Mulroney spoke at a University of Toronto conference, Diplomacy in the Digital Age, Oct. 13, an event held in honour of Alan Gotlieb, the former ambassador to the United States who served three prime ministers. (more…)

*One youngster only six times heftier than Jupiter*

TORONTO, ON – A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters. What’s more, one cluster contains a surprising surplus of them, harbouring half as many of these astronomical oddballs as normal stars.

“Our findings suggest once again that objects not much bigger than Jupiter could form the same way as stars do. In other words, nature appears to have more than one trick up its sleeve for producing planetary mass objects,” says Professor Ray Jayawardhana, Canada Research Chair in Observational Astrophysics at the University of Toronto and leader of the international team that made the discovery.

*Consumers have access to more than one advertising medium today*

Not allowed to advertise your booze or smokes on a billboard? That’s okay. Research shows online advertising works especially well in places with government ad bans.

“If you want to regulate the offline world, you have to remember that people have access online too and you have to think about how that online world is going to mitigate the effects of your regulation,” said Avi Goldfarb, a marketing professor at the University of Toronto’s Rotman School of Management who co-wrote a study on the topic with Catherine Tucker of MIT’s Sloan School of Management.

GAINESVILLE, Fla. — When a movie character says, “It’s too quiet,” that’s usually a sign something bad may happen.

Now, University of Florida researchers have discovered that when variations of a certain protein in our cells are too quiet, it may add to the risk that someone will develop lung cancer. When scientists restored the protein to its normal, active self, its cancer-inhibiting properties reappeared. (more…)

Talking to yourself might not be a bad thing, especially when it comes to exercising self-control.

New research out of the University of Toronto Scarborough – published in this month’s edition of Acta Psychologica – shows that using your inner voice plays an important role in controlling impulsive behaviour.
