Microraptor was an opportunistic predator, feeding on fish, birds, lizards – and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
“Our research shows that climate change is having substantial impacts on Arctic ecosystems, with consequences for exposure to toxic pollutants like mercury,” says co-author Jean-Pierre Desforges, a Postdoctoral Fellow [NRS] at McGill University under the supervision of Nil Basu [NRS/SHN] and Melissa McKinney [NRS].
In the Arctic, climate change and pollution are the biggest threats to top predators like narwhals. Studying the animals’ tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.
Can mindfulness training help overweight people shed pounds and keep them off? McGill University researchers surveyed the growing body of studies investigating that question, and came away encouraged.
Kimberly Carrière, Bärbel Knäuper and Bassam Khoury examined 19 studies conducted over the past decade. Mindfulness interventions in these studies involved either formal meditation, informal mindfulness strategies that focused on eating activity, or some combination of these two approaches.
