Queen's researcher finds new model of gas giant planet formation

Dr. Martin Duncan's new model proposes that gas giants like Jupiter and Saturn formed through the accumulation of small 'pebbles', allowing cores to form rapidly enough to capture their atmosphere. The successful model predicts the formation of one to four gas giant planets, consistent with the observed outer solar system configuration.

Instant oatmeal for breakfast may help curb your appetite at lunch

A study published in the Journal of the American College of Nutrition found that eating instant oatmeal for breakfast significantly reduced food intake at lunch. The researchers attributed this effect to the higher molecular viscosity of beta-glucan in instant oatmeal, which enhanced satiety and feelings of fullness.

The pronoun I is becoming obsolete

Recent studies have shown that thinking of plants and animals as autonomous individuals is a serious over-simplification.
