Benzene is one of chemistry's great stars. It has numerous applications, and is the basis for manufacturing many more useful compounds. But did you know its structure was a subject of a lot of controversy in the 19th century?
Just a hundred years ago, drugs were expensive and had to be obtained from exotic tropical trees. This changed with the discovery of an artificial compound called Salvarsan. It cured the dreaded disease syphilis and laid the foundation of modern medicine.

Over millions of years, plants and animals have evolved materials with amazing properties - the sticky feet of geckos, spiders' silk, self-cleaning lotus leaves. Scientists are now learning to make products in the lab that imitate their properties; these are called biomimetics.
Every once in a while we fall sick. Our parents use a thermometer to check how sick we are or if we are pretending so that we don't need to go to school. This little instrument is very reliable in telling how warm we really are.

Pitchblende, also known as Uraninite, is a uranium rich mineral. This mineral forms one of the primary ores of uranium, containing almost 50 to 80 percent of it.
We have heard that photosynthesis is the process by which a plant converts solar energy to chemical energy by using chlorophyll. What you might not know is that scientists in France have discovered a way to use the same photosynthesis into electrical energy.
We spend a lot of the time in the class room watching teachers write on the blackboard with chalk. But when was the first time that we started to use this little white stick?
