A Superior Court judge ruled that a large nurses union must adhere to the vaccination policy set forth by Brigham and Women’s Hospital in Boston. If not for this decision forcing the Massachusetts Nurses Association to comply, the nurses avoiding a flu shot would have posed a potential threat to patients they tend to each day. 

Obesity is known to be a major risk factor for type 2 diabetes, as well as for the insulin resistance that's a hallmark of the disease. Mouse studies suggest that obesity results in the production of microRNAs by adipose tissue, which diminishes the ability of tissues to respond to insulin.

Scandals, no matter their size or consequence, shouldn't eradicate the basic tenets of doctor-patient privilege.

Even though the service is free, a recent survey showed that 3 in 4 British citizens use the internet to self-diagnose and treat themselves, rather than schedule a doctors' visit using the UK's National Health Service. Imagine if more people used it.

The odd case of a stricken man arriving at a Florida hospital with no ID, no family member – but with a bold tattoo stating that critical, life-saving intervention be withheld – is serving as a bizarre but essential reminder to the rest of us to raise a difficult, yet frequently-skirted, topic.

It's always good to take a moment to reflect on science’s beauty and power to inform, to improve our lives when not constrained by ego, status, publish-or-perish constraints, or the new-media landscape.
