We examined the relationship between persistent osteoporosis medication use and fracture risk among female Medicare beneficiaries diagnosed with osteoporosis using Medicare claims, 2009–2012. Persistent use was associated with reduced risk of fracture and significantly lower total health care costs in the follow-up period. Results were consistent using different analytical methods.

There appears to be a cumulative relationship between number of pregnancies and more accelerated biological age.

By drawing in a bit of sweat, a patch developed in the lab of Alberto Salleo can reveal how much cortisol a person is producing. Cortisol is known as the stress hormone but is involved in many important physiological functions.

Oisin Biotechnologies is the company working on what is, to my eyes, the best of the best when it comes to the current crop of senolytic technologies, approaches capable of selectively destroying senescent cells in old tissues. Adding senescent cells to young mice has been shown to produce pathologies of aging, and removal of senescent cells can reverse those pathologies, and also extend life span. It is a very robust and reliable approach, with these observations repeated by numerous different groups using numerous different methodologies of senescent cell destruction.
