1. We are
one step closer to helping paralyzed people walk again. Neuroscientists in
Switzerland are using electronics to restore movement
in paralyzed rats –
so far, these rats have been able to take 1,000 computer-controlled steps.
2. The AIDS epidemic gained notoriety in the 1980s, but by using genetics and historical records, scientists have traced the “epidemic ignition” of the HIV virus back to the 1920s in the Congo (called Kinshasa at the time). An excellent piece describing the study is here.
3. Having
trouble recognizing the smells coming from the kitchen? Or the flower garden?
It could mean your number is up. A new

and death.

4. Does
anything really ever “touch” another thing? Physics
says NO! Watch this remarkable video addressing this “touchy” subject:
5. Ever wonder
why most people instinctively tilt their head to the right when leaning in for
a smooch? Find out the answer to that as you learn “The Scientifically Best Way
to Kiss”:
Science quote of the week:
“The first principle is that you must
not fool yourself and you are the easiest person to fool.” –Richard P. Feynman
