Hospital scanners could control cell-sized medical devices |
Hospital scanners could control cell-sized medical devices (Mar 20)
http://physicsweb.org/article/news/11/3/14
Physicists in Canada have used a conventional magnetic resonance imaging
(MRI) system to control the movement of a small metal bead inside blood
vessels. The experiment demonstrates that MRI systems could eventually
control tiny "untethered" devices that perform truly non-invasive
surgery (App. Phys. Lett. 90 114105).

Whenever somebody tells you that a miracle of robotics is attached to
a knife, your first thought should include three adjectives:
idiosyncratic, nosocomial, and iatrogenic. An idiot-simple piece of
"qualified" hardware allowed to operate without intelligent (meat)
oversight will kill, and does:

***{Very interesting. AECL, which was responsible for the THERAC-25
disaster, is a sort of Canadian version of the U.S. Postal Service,
except that instead of delivering letters incompetently and at excessive
cost, they deliver nuclear services incompetently and at excessive cost.
Of course, that's just government: whatever they do is done
incompetently, and at excessive cost. If nuclear power had been totally
unregulated from the beginning, private companies would have been
delivering nuclear fuel pellets to small home reactors for 40 years,
just as they deliver coal, heating oil, and propane for home use today,
and by now the improvement of nuclear technology due to competition in
free markets would have resulted in human colonies on the Moon, Mars,
and beyond. But we couldn't permit any of that. We knew it would be
safer to entrust the most revolutionary technology ever discovered to
the most inept and dysfunctional types of organization ever discovered.
That had to lead to good outcomes all around, right? :-) --MJ}***
