How To: Break chemical bonds

A difficult concept for many students to understand is the energy involved in breaking and forming bonds. A hydrate is a substance that has water bonded to it. In order to dehydrate you must add energy (endothermic) to break the bond to water. When hydrating you are forming a bond to water and will release energy (exothermic). This visual demonstration reinforces the concept.

News: Researchers Look to Cows to Create Vaccine for HIV

A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
