The journey of the self, through the self-to the self

[Shining Science @ShiningScience]

Centuries before dental clinics, the ancient Maya used sophisticated jade fillings to treat toothaches.

For decades, archaeologists have uncovered Maya teeth decorated with precious stones like jade and pyrite. Traditionally, researchers believed these alterations were purely cosmetic, representing a form of ancient 'grill' for social status or rituals. However, a new analysis of a back molar containing a jade inlay is challenging this assumption.

Since this hidden tooth would not have been visible in normal social interactions, researchers suggest the procedure was functional. Further examination using 3D imaging revealed calcification within the tooth's pulp, indicating that the individual was alive when the filling was placed and that the procedure was likely done to relieve pain or treat a cavity.

The study also highlighted the incredible durability of the organic cement used to bind these stones to the teeth. Analysis of these ancient sealants revealed a mixture of calcium, phosphates, bitumen, and essential oils that have remarkably outlasted modern-day fillings. Many of these jade inlays have remained firmly in place for over a millennium, showing that Maya practitioners possessed advanced pharmaceutical and metallurgical skills. These findings suggest that the Maya were not only masters of aesthetic modification but also pioneer dentists who developed enduring therapeutic treatments long before the era of modern medicine.

Miles de peces, la mayoría sardinas, fueron hallados muertos a lo largo de 200 metros de playa en la zona de Punta Caracol, en Puerto Morelos, un fenómeno que habitantes, pescadores y prestadores de servicios relacionan con el mayor recale e sargazo en los últimos años.

The ground beneath Mexico City is slowly sinking, and now, the NISAR satellite can track it from space.

New data shows parts of the city (in blue) that sank more than half an inch (more than 2 cm) per month from Oct. 2025 to Jan. 2026.

We arent just witnessing a decline; we are witnessing an unravelling of the systems that make our air breathable and our soil alive. New data from the Living Planet Index confirms a terrifying reality: global wildlife populations have plummeted by 73% in just 50 years (1970–2020).

The burden of this extraction is not shared equally. The Global South is being hollowed out to fuel endless growth:

Latin America & Caribbean: -95%
Africa: -76%
Asia-Pacific: -60%
North America: -39%
Europe & Central Asia: -35%

This isnt an accident. It is a calculated result of:
1. Industrial Food Systems: Forests cleared for meat and soy.
2. Fossil Fuels: Driving a climate collapse that bleaches reefs and melts habitats.
3. Endless Extraction: Rivers choked by dams and chemicals for profit.

Every extinct species is a warning sign. Every forest cut is a wound. We, specifically our economic systems and the wealthy elite, are acting as the asteroid.

The window to change is closing fast. We must move beyond. We must BOYCOTT FOSSIL FUELS.
