Depends on the goal. If maximizing quality and length of life under constrained resources, prevention is more effective. But, as you mention, prevention does have inherent limits on life span. Biotechnology could allow further, perhaps i

There is a fair bit of focus on it. I'm not sure if that is because of the ease of building them or the need for it - it is a fairly critical organ and there is a shortage of donors. I believe the challenge is the vascular (blood vess

The work behind this is the result of a huge effort, starting 20-30 years ago. Some people had given up on the promise of tissue engineering - one of my mentors suggested just over a year ago to me that the field was a poor choice to start

This is a very different method (FT-IR spectroscopy) than the device the original article uses (measuring electrical impedance). It is less surprising to me that FT-IR would be able to give accurate results - I would think the challenge wo

Non-invasive glucose monitoring is a holy grail of biomedical engineering. For diabetes management alone, it would be a multi-billion dollar product. This questions why it would be launched in this sort of way - the credientials of the pe

The arcs are from a single 'ping' from a single satellite. The satellite knows where it is, and with the 'ping' it was able to determine the distance from the satellite to the aircraft. The satellite is the distance of

This requires the pilots to discover the fire at the exact time when switching from Malaysian Air Traffic Control to Vietnamese Air Traffic Control. The fire then incapacitates the radio or the pilots before they have a chance to call in t

Interesting that the surgery was in 2012 but only coming to press now. Perhaps it was only recently published?

Usually automated image processing is tough without a priori info about the image, or some human input. Adding to these methods, a 'holes' fill algorithm can be very helpful. This would proably be used in place of your Alpha Mask

Indeed. These sensors are the impressive part of wearables, it will be tough to build a differentiated product on top. Invensense becomes the Apple/Samsung, and the wearable maker becomes an app, but with hardware development timelin

There is a key advantage to what this is doing over current activity trackers I am aware of - and that is that it gives real time feedback and is moving towards performance metrics that matter rather than merely tracking how much the sensor

I'm doing a PhD in the UK, and there certainly are people who are doing a PhD without funding (and paying quite high tuition, outside the EU is nearly £20k/yr), although they are a minority. I would guess 10%, less in STEM subject
