'll sing it, you play it
If you don't own an
instrument, and want to test out your new melodies, new software will
provide backing chords to go with your song. Just sing into a
microphone and MySong, created by Microsoft, will play it back to you
with a piano accompaniment.
Curious clouds linked to quakes
cloud formation offer a warning of an impending earthquake? This is the
question being asked following the discovery of distinctive gaps in
clouds in satellite images above an active fault in Iran, before two
large earthquakes struck. The geophysicists from China, who noticed the
clouds, suggest an eruption of hot gases from inside the fault could
have caused water in the clouds to evaporate.
The upside of a crisis
crises have health benefits. When Cuba was hit with a food and fuel
crisis in the 1990s, it may have made life miserable in the short term,
but it led to long-term improvements in Cubans' health. By walking more
and eating less, the population's obesity rate halved and the deaths
from potentially fatal diseases fell dramatically.
