Somewhere outside Sarajevo, Bosnia, looming over a small town called Visoko, sits the mysterious Visocica hill, which renegade researchers now claim to be a man-made structure: a pyramid estimated to be 235m high, one-third taller than the Great Pyramid of Giza in Egypt.

While experts say there is no scientific basis for his claims, 45-year-old Semir Osmanagic, an amateur Bosnia archeologist who has spent the last 15 years studying the pyramids of Latin America - is convinced that sitting underneath the hill is a giant step pyramid.

Antarctica, the icy bottom of the world, is one of the planet's last great wildernesses. With no permanent residents, the continent is managed by a treaty, which was signed by 12 nations in 1959 and was renewed in 1991. The treaty allows these countries, including the U.S., to conduct research in Antarctica, but calls the continent a natural preserve, "devoted to peace and science." But now another country down under is trying to undermine the treaty.

Late last year Malaysian fish farm workers claimed to have had a sighting—Bigfoot, Sasquatch, or Yeti—mythical creatures often relegated to the pseudo-science known as cryptozoology. Three enormous and hairy humanoids were spotted roaming the jungle of Johor. While the Malaysian wildlife department investigates these reports, photographs of the 17” footprints circulate the internet alongside reports of large odorous hairs.
