A short-term study found that oral glucosamine supplementation is not associated with a lessening of knee cartilage deterioration among individuals with chronic knee pain. Findings published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR) journal, indicate that glucosamine does not decrease pain or improve knee bone marrow lesions—more commonly known as bone bruises and thought to be a source of pain in those with osteoarthritis (OA).

The protector species, the weaver ant Oecophylla smaragdina, can also turn predator of the associate species, the jumping spider Phintella piatensis.
A timid jumping spider uses the scent of ants as a secret weapon to save itself from becoming the somewhat soggy prey of the predatory spitting spider. The downside to this plan is that jumping spiders are also a favorite snack of its very own saviors. To overcome this additional hazard, the spider has made yet another plan in the form of an ant-proof nest, writes Ximena Nelson of the University of Canterbury in New Zealand and Robert Jackson of the University of Canterbury and the International Centre of Insect Physiology and Ecology in Kenya, in Springer's journal Behavioral Ecology and Sociobiology.
