The Blue of a Spider

Episode 029 Got the blues? Well, someone who’s really blue -- but likes it -- is the cobalt blue tarantula. This large spider gets its color not from a pigment, but from tiny structures in its hair, which cause the reflected light to display an effect called interference. The same interference effect causes soap bubbles, opals, and butterfly wings to display many different colors depending on what angle you view them from. What is remarkable about the cobalt blue tarantula is that the color doesn’t change in this way, but stays the same.

Nanodentistry

Episode 028 Teeth make eating possible, sharks scary, and smiles pretty. But when you have a cavity, you need to see a dentist. For over 200 years, dentists have been filling cavities with amalgams, which are mixtures of silver, mercury, and other metals. Since the 1970s, however, dentists have increasingly been using a new material called a composite, which is made by adding powdered quartz to a plastic resin.

The Nanotechnology of Batteries

Episode 027 Batteries are an amazing technology. Each battery is a little chemical reactor: when power is needed, the chemical reaction proceeds, and electricity is generated. When the chemical reaction ends, the battery is dead. Of all the kinds of batteries, lithium-ion batteries have the greatest energy per unit weight, which is why they are used in such things as laptop computers.

Photothermal Therapy – Can You Take the Heat?

Episode 025 If the cells in your body get hot, they get a little uncomfortable and don’t work as well. Unlike us, they can’t just drink some ice-cold lemonade to cool off. Your cells can only live near body temperature, and if things get too hot, they die. This is true for normal cells, and also for cancer cells.
