Sex versus survival: A tradeoff at geographical range limits

...that plants growing in harsh northern climates are losing the ability to reproduce sexually, an evolutionary phenomenon similar to the loss of sight in cave-dwelling fish.

Hold the stuffing: Low-glycemic diet may help keep weight off

...39 subjects who remained in the study succeeded in losing about 10% of their initial body weight. The low-GL dieters had smaller decreases in resting energy expenditure (averaging 96 kcal/day, or 5.9%) than the low-fat dieters (averaging 176 kcal/day, or 10.6%), meaning their metabolism did not slow as muc...
