In a curious new study, researchers have realized that pesticides in fruits and vegetables may affect the quality of men's semen.
It turns out that fish sperm makes excellent flame retardants, according to new research.
Here's something you don't hear every day: Fish sperm could be a key ingredient involved in extracting and recycling rare earth elements (REEs) from used ore and electronic waste. This could provide a very natural, albeit strange, alternative to modern chemical-based extraction methods.
