Surgery Using A Sunlight Scalpel
Makarand writes "Research conducted by Israeli doctors has shown that it is possible to use
concentrated sunlight instead
of lasers to perform surgery, providing a safe and
low cost alternative to laser treatment.
In their experiments sunlight was transported into the operating room
from outside using a system of optical fibers.
The concentrated rays - containing several watts
of energy - were then used in the experimental surgery conducted
on rats." Here is Wired's similar story.
AFAIK, winter = cold season.
Wrong. Winter is defined as (from dictionary.com)
"The usually coldest season of the year, occurring between autumn and spring, extending in the Northern Hemisphere from the winter solstice to the vernal equinox, and popularly considered to be constituted by December, January, and February. "
Generally, its understood that winter (in the northern hemisphere at least) is the time when the earth tilts on its axis and the northern hemisphere is furtherst from the sun.
