  • Medical incubator was purposely invented to regulate the body temperature of newborn babies
• Erythromycin

• 16-bit microchip


  • Created by Diosdado Banatao
  • First single chip graphical user interface accelerator
  • This chip allows computer users to make graphical presentations using graphics for commands
  • Data processing is much quicker using small chip instead of large board
• Anti cancer cream


  • Developed by Rolando dela Cruz
  • He developed an anti cancer cream from cashew nuts and other local herbs to treat Basal Cell Carcinoma (BCC) which is considered to be the most prevalent type of skin cancer
  • He called this cream DeBCC cream, which won him a gold medal in the International Inventor's Forum in November 2005
