Here are some scientifically charged emojis. They symbolize scientific progress, discovery, research in such fields as biology, chemistry, astronomy. You can use them in the following sense:

• Microscope — I am a great scientist. I can peep on bacteria's mating.
• Telescope — I watch people mate right across the street. Sometimes I turn my eyes to the sky and I see stars. But it's a rare occasion.
• Test tube and genome — it's designed for those who are working on developing chemical and biological weapons.
• Alembic actually symbolizes a device for making moonshine.
