Physics Of Sailing
Physicists know the secrets
of sailing that many novice
sailors do not. A boat does
not go fastest when the wind
blows from directly behind
it, but when the wind comes
from the side. With the
sails at the correct angle,

Flying and Radiation Risk
At the high altitudes and
latitudes commercial
airlines fly, crews are
subjected to
higher-than-normal radiation
levels from the sun and
cosmic rays. Physicist

Bringing Sunlight Inside
Photovoltaic panels have a
new design: concentric
circles that focus the sun's
rays on miniaturized
modules. Having the panels
automatically sense sunlight
and turn towards it also

Turning Trash Into Power
A new kind of waste digester
uses two different strains
of bacteria in different
tanks. This would normally
take place in the same
environment, but
microbiologists have now

Energy Scientists Propose Color-Coding Standard for PC Sleep Mode
Different computers use different indicator lights to signal that they are in energy-saving, or "sleep" mode. Users are often unsure if their PC is truly saving energy, rather than just turning its ... > more -
Mimicking Insects to Avoid Sinking Using Surface Tension
A new robot made of ultralight carbon-fiber can stand or slowly walk on water. The principle it uses is borrowed from insects -- surface tension tends to prevent the water's surface from breaking, ... > more
