Yawning	A common human behavior with unclear purpose.	May cool the brain or regulate alertness; reason remains debated.
Fungus Curiosphaera gaster	Rare fungus appearing only in Texas and Japan along the same latitude.	Unexplained regional restriction; possibly environmental or genetic.
Humpback Whale Gatherings	New behavior of humpback whales feeding in large groups off South Africa.	Possibly due to population recovery; specific triggers remain unknown.

UFOs / UAPs	Unidentified flying or aerial phenomena observed globally.	Most reports explainable by human-made objects or natural causes; no proven extraterrestrial involvement.
Ghosts	Apparitions or perceived presences of the dead.	Lacks scientific evidence; often explained by psychological or environmental factors.
Loch Ness Monster	Aquatic creature said to inhabit Loch Ness, Scotland.	Numerous sightings, but no biological evidence; sonar studies have been inconclusive.
