In terms of physics, there is hardly any difference between the resonance in a molecule and a musical chord. Both are created when vibrations with different frequencies overlap. In music, it is the notes that make up the chord.

Most of us take it for granted that plants respond to light by growing, flowering and straining towards the light, and we never wonder just how plants manage to do so. But the ordinary, everyday responses of plants to light are deceptively complex, and much about them has long stumped scientists.

Termites - notorious for their voracious appetite for wood, rendering houses to dust and causing billions of dollars in damage per year -- may provide the biochemical means to a greener biofuel future. The bellies of these tiny beasts actually harbor a gold mine of microbes that have now been tapped as a rich source of enzymes for improving the conversion of wood or waste biomass to valuable biofuels.

The next time you take a moonlit stroll, or admire a full, bright-white moon looming in the night sky, you might count yourself lucky. New observations from NASA's Spitzer Space Telescope suggest that moons like Earth's - that formed out of tremendous collisions - are uncommon in the universe, arising at most in only 5 to 10 percent of planetary systems.

The delay in autumnal leaf coloration and leaf fall in trees is caused by rising levels of carbon dioxide (CO2) in the atmosphere and not by increased global temperatures, suggests a new study by researchers at the University of Southampton.

Honeybees somehow manage to efficiently collect a lot of nectar with limited resources and no central command - after all, the queen bee is too busy laying eggs to oversee something as mundane as where the best nectar can be found on any given morning. According to new research from the Georgia Institute of Technology, the swarm intelligence of these amazingly organized bees can also be used to improve the efficiency of Internet servers faced with similar challenges.
