Impact of tuition fee increases on medical students

A study by Jeff Kwong and colleagues found that tuition fee increases in Ontario are disproportionately affecting lower-income students, with fewer from these backgrounds enrolling in medical school. The researchers also noted that first-year Ontario students expect higher debt loads at graduation than their peers in other provinces.

The brain risks of binge drinking

A new study confirms that binge drinking can cause neuronal damage in the brain. Damage to the olfactory bulb occurred after just two days of 'binge drinking', while other regions were damaged after four days. The study suggests that alcohol-induced brain damage occurs during intoxication, not withdrawal.
