Researchers raise doubt about morning sickness drug
The most commonly prescribed drug for pregnant women suffering from morning sickness in their first trimester does not prevent birth defects even though drug safety data says it does, new research has found.

How far away do you think that finish line is?
Why does the second hour of a journey seem shorter than the first? Why does the café 50 metres ahead of you feel closer than the one 50 metres behind you? New research from the University of Toronto Scarborough and U of T's Rotman School of Management shows the answer has to do with how you're physically oriented in space.

Lowering cholesterol by eating chickpeas, lentils, beans and peas
Eating one serving a day of beans, peas, chickpeas or lentils can significantly reduce “bad cholesterol” and therefore the risk of cardiovascular disease, a new study has found. However, most people in North America would have to more than double their consumption of these foods known as pulses to reach that target, said the researchers at St. Michael's Hospital.

Strong dollar means cross-border shopping heavily influenced by exchange rate
Even a one cent increase in the exchange rate causes a disproportionate number of Canadians to go cross-border shopping, according to a new study from a team of researchers that included Professor Ambarish Chandra of the University of Toronto Scarborough and Rotman School of Management. “When the home currency is strong, as is the case in Canada at the moment, even a slight jump in the exchange rate makes a big difference because it expands the set of goods they can find cheaper in America,” says Chandra.
