Amazing.
Not that you didn't know this already, but I was part of this study (treatment group, I had osteoporosis):

Amazing.
"Serum sclerostin decreases following 12 months of resistance- or jump-training in men with low bone mass" in the Bone Journal is competing for attention with It’s official: Running is the best exercise you can do in the NY Daily News. There's a lot of work left to do.
After breathlessly reporting running's exclusive life-extending powers for many, many excited paragraphs, the NY Post article remembers to finish with this: "The researchers stress that running is not the cause for a longer life, but supportive of it and that other factors included in living healthfully increase the chances of living as many years as possible."
Gotta love clickbait.
The first question that comes to my mind about this study is whether they controlled for intensity in the other activities. You can bike, walk, swim, and even "resistance train" (think pink dumbbells) without elevating your heart rate much. With running, there's a minimum level of intensity required since you have to have both feet off the ground at the same time.
I'm not a scientist and don't have access to the full text, but it seems to me that if you set out to study running vs. everything else, you can find a way to frame your research such that running comes out ahead.
