There’s a major discovery that sheds new light on the origins of life on Earth. Scientists have found the oldest direct proof of oxygenic photosynthesis, the process of converting sunlight into energy and oxygen, in fossilized bacteria from Australia and Canada. These fossils, dating back 1.75 billion years, push back the confirmed origin of photosynthesis as we know it by at least 1.2 billion years.1 Photosynthesis in Life’s Development Photosynthesis is essential for life as it produces available oxygen, which is vital for most organisms. While scientists believe photosynthesis originated about 3.5 billion years ago, it was initially a primitive …

Scientists have discovered that massive geological events can send “fountains of diamonds” shooting up from deep within the Earth’s crust. This explosive phenomenon occurs when supercontinents break apart, creating conditions that propel diamonds to the surface in dramatic eruptions. These eruptions, known as kimberlite eruptions, are powerful and incredibly fast, capable of launching these precious gems at speeds of up to 83 miles per hour (133 kilometers per hour). The Mechanics behind the Magic So, how exactly does this natural marvel happen? The process begins deep below our feet, where diamonds form around 62 miles (150 kilometers) underground. When tectonic …
