Hopping Relatively Recent Development in Kangaroos

Hopping Relatively Recent Development in Kangaroos

Kangaroos are known for their characteristic hop, but they didn’t always get around like this. Analysis of the fossilized bones of extinct kangaroos called sthenurines finds that they were not anatomically cut out for hopping and likely got around instead by walking in much the same manner that humans do. Sthenurines lived in Australia from about 13 million years ago to about 30,000 years ago, going extinct around the same time that humans arrived on the continent, quite possibly as a result of human activities.

Knee Replacement Overuse Concerns

Knee Replacement Overuse Concerns

In the past two decades, the number of total knee replacements in the US has more than doubled, and there are concerns that not all of them are justified. Recent research seems to validate these concerns, suggesting that a third of the osteoarthritis patients in the US that undergo total knee replacements are inappropriate for the procedure. Most of them had only moderate symptoms and limited joint damage. Part of the problem appears to be a lack of a standard in criteria for evaluating potential knee replacement candidates.

Eat Your Veggies!

Eating cruciferous vegetables like broccoli, Brussels sprouts, or cabbage might slow the progression of—or even prevent—osteoarthritis. In mice, sulforaphane, a compound created in these vegetables when they are eaten, blocked a key cartilage-damaging enzyme. Researchers are now investigating whether sulforaphane will do the same for humans. For two weeks before knee surgery, 20 arthritis sufferers will eat a specially bredbroccoli variety that contains high levels of glucoraphanin, the compound that becomes sulforaphane. The tissue that is removed will then be examined for signs of sulforaphane’s benefits. More… Discuss
