JAPANESE researchers have
released details of ultra-thin
electronic “skin” which
is able to measure oxygen levels
when attached to the body.
The latest development in
“wearable electronics” could
eventually be used to monitor
oxygen levels during surgery,
according to the scientists from
the University of Tokyo.
Currently only at a prototype
stage, the device contains micro-electronic
components which
can light up in different colours,
with the report on the findings in
Science Advances saying the next
stage will be to display numbers
and letters on the skin to monitor
different conditions.
HAIRY ants are able to resist heat
much more effectively than non-hairy
ants.
How would you prove this? By
shaving them, of course.
That was the intriguing project
undertaken by researchers at
the Free University of Brussels,
who were aiming to discover the
survival techniques of Saharan
silver ants which can survive
temperatures of more than 50°C.
They compared normal hairy
ants with some which had been
shaved using a tiny scalpel blade
using the assistance of a high
powered microscope, measuring
the amount of light reflected and
how fast they warmed up under a
heat lamp.
The unshaven ants were almost
ten times more reflective than
the bald ones, which kept them
as much as two degrees Celsius
cooler, the scientists found.
