So just to clarify, this "new research" is on mortality. There are still many health benefits from standing AND/OR alternating sitting/standing throughout the day... those benefits just might not be a reduction in heart disease or diabetes.
I've had a standing work desk and also a standing home desk for 5 years. I alternate standing/sitting throughout the day. I personally have noticed an in increase in flexibility in my hip flexors, hamstrings, glutes, and general tightness in my lower back. I'm a pretty active and fit person, so I really enjoy being able to stand and sit whenever I fee like I need to stretch or relax my muscles, respectively.
I don't think standing all day is healthy... I think that's bad for your knees and back. But I do believe that it's very beneficial to alternate stand/sit frequently (hourly or so).
