Nature
The smell of rain has a name — petrichor — caused by an oil released by plants and a compound produced by bacteria.
13
Human Body
Your skin is home to roughly 1,000 species of bacteria per square centimeter.
14
Human Body
There are more bacterial cells in your body than human cells — roughly 38 trillion vs. 30 trillion.
15
Ocean
The Dead Sea is so salty that nothing larger than bacteria can survive in it, and swimmers float effortlessly.
16
Food
Sourdough bread is made from a 'starter' — a live culture of wild yeast and bacteria that can be maintained for decades.
17
Science
CRISPR gene-editing technology is based on a natural immune defense mechanism found in bacteria.
18
Science
Mitochondria have their own DNA, separate from nuclear DNA, supporting the theory that they were once independent bacteria.
19
Science
Vinegar is produced by bacteria converting ethanol to acetic acid — a two-stage fermentation process.
20
Technology
Self-healing concrete, embedded with bacteria that produce limestone when cracked, could dramatically extend building lifespans.
21
Nature
The smell of rain on dry earth is called petrichor — it's caused by a compound called geosmin released by bacteria.

Self-healing concrete embedded with bacteria could dramatically extend building lifespans.
23
Science
Honey found in Egyptian tombs 3,000 years old is still edible — its pH and low moisture prevent bacteria.

Nature
The smell of rain on dry earth is called petrichor — caused by a compound called geosmin from bacteria.
25
Science
Acetic acid, the active compound in vinegar, is produced by bacteria fermenting ethanol in wine.
26
Science
Freezing food does not kill bacteria — it pauses their activity. Thawing can allow rapid growth if done improperly.
27
Science
The average person has between 500 and 10,000 different species of bacteria in their gut.
28
Science
Penicillin-resistant bacteria were identified within 3 years of penicillin's widespread introduction.
29
Science
Alexander Fleming noticed that a mold contaminating his petri dish killed bacteria — and followed up on the observation.
