🇨🇳BONE GLUE. That's what Chinese scientists have invented, and it fixes broken bones in 3 minutes.

No metal plates. No screws. No big surgery. Just inject it, and the broken pieces bond together in minutes, even in a bloody surgical site.

In one trial, a shattered wrist was fully repaired through a tiny 3cm cut. Three months later, full recovery, zero complications.

Over 150 patients have already been treated. Clinical trials are ongoing.

🟥 ⛏️ The Richat Structure
often called the Eye of the Sahara, is a prominent geological feature in the Adrar Plateau of Mauritania's Sahara Desert.

▶️ It manifests as a large, slightly elliptical dome approximately 40 kilometers in diameter.

Characterized by concentric rings of exposed sedimentary rock layers that create a striking bull's-eye pattern visible from space.

These layers range from Late Proterozoic to Ordovician in age, with the innermost parts revealing older strata due to erosion.

▪️ The outer rings consist of dipping cuestas formed by alternating hard and soft rock types, such as quartzites and shales.

▪️ While the central depression a limestone-dolomite shelf enclosing a kilometer-scale siliceous mega-breccia.

▪️ This breccia is a chaotic mix of angular fragments cemented by silica, often altered by hydrothermal processes that introduced minerals like authigenic potassium feldspar.

▪️ Intrusive elements include gabbroic ring dikes, carbonatite dikes and sills, kimberlitic plugs, and alkaline volcanic rocks such as rhyolites and basalts, reflecting a bimodal tholeiitic-alkaline composition.

▶️ The mineral assemblage highlights alkaline enrichment, with carbonatites dominated by calcite and dolomite

Alongside minor apatite and pyrochlore, and kimberlites containing olivine, phlogopite, and perovskite phenocrysts in a groundmass of serpentine and carbonate.

▶️ This structure formed during the Cretaceous period, around 94 to 104 million years ago, as an isolated alkaline-hydrothermal complex.

▪️ It originated from the intrusion of a large magmatic body beneath the sedimentary sequence, causing doming and uplift of the overlying rocks into an anticline.

▪️ Magmatic activity involved the emplacement of tholeiitic gabbroic dikes and rhyolitic centers, followed by carbonatitic and kimberlitic injections that crosscut earlier features.

▪️ Hydrothermal fluids associated with this magmatism led to karstification, dissolving limestones, and creating voids filled by the siliceous breccia through low-temperature silica precipitation.

▪️ Over time, differential erosion sculpted the dome: resistant layers like quartzite formed ridges, while softer shales and altered zones eroded into valleys, enhancing the concentric appearance.

↘️ The entire process reflects a multi-stage caldera-like system with superimposed magmatic chambers, without evidence of meteorite impact.
