Ever seen a mummy from Papua, Indonesia? These aren’t Egyptian mummies wrapped in linen. In the Baliem Valley around Wamena (in Highland Papua, on the Indonesian side of New Guinea ) the Dani (Hubula) people used to preserve respected leaders by smoking the body over a low fire inside a honai for weeks, then rubbing it with pig fat. The result is a blackened, dried figure still sitting in a crouched position. These mummies aren’t souvenirs. For the community they are living ancestors: guardians of the village, sources of blessing, and a link to who they are. Only war leaders or chiefs received this honor. The practice has mostly stopped, but a few centuries-old mummies are still cared for by their descendants. If you visit, be respectful. Don’t touch. Photos are usually allowed with permission and a small contribution toward their upkeep. Science and facts💡

A traditional technique practiced by the young shepherds of the Banna tribe of Ethiopia. They walk on stilts to watch over their cattle among the tall grass, move through swampy areas, and protect themselves from snakes and predators like lions and leopards. Science and facts💡

How long things actually take to disappear. Some everyday items break down in weeks, while others can remain in the environment for centuries. A banana peel may decompose in a few weeks, but a plastic bottle can persist for hundreds of years. These estimates are a reminder that what we throw away doesn’t simply vanish. It can remain part of the environment long after we’re gone. Science and facts💡

Most “wasabi” you’ve ever eaten wasn’t wasabi. This is the real plant. Those broad, glossy, heart-shaped leaves belong to Eutrema japonicum. The famous green paste doesn’t come from the leaves, it comes from the slow-growing rhizome hidden beneath them. Real wasabi is rare, perishable, and expensive. That’s why so much of what gets served worldwide is actually dyed horseradish. This is what the genuine thing looks like before it ever reaches a grater. Science and facts💡

Chasing the grind! Inside a pepper mill 👀 Science and facts💡

The Burj Khalifa rises 828 meters. Getting water up is the famous problem. Getting waste back down was the messier one. When the tower opened, Dubai’s sewage plants were already over capacity. The city’s growth had outrun the pipes. For years, tanker trucks formed long convoys to haul wastewater to treatment plants, drivers sometimes waiting hours to dump a load. Inside the building, sewage can’t just free-fall 160 floors. That would smash pipes and blow toilets on the way down. Engineers designed the stacks so waste spirals along the walls, keeping an air core in the middle and bleeding off pressure before it hits the municipal line at the base. The tower got built. The sewer network spent the next decade catching up. Dubai is still pouring billions into deep sewage tunnels so the trucks don’t have to do that job anymore. Science and facts💡
