Were There Any Signs Before Mt. Pelee’s Eruption in 1902?

Every natural disaster comes with signs. Before a volcano erupts, you would notice several things like subtle swelling of the ground, small changes in heat flow, and even noticeable steaming from the ground around the area. Animals may also serve as indicators of an upcoming disaster. Was this the same case with the eruption of …

What is Bioprecipitation?

David Sands from Montana State University conceptualized the idea of bacteria making rain. While were are familiar with the idea of precipitation, how true is his theory on bioprecipitation?  In Meteorology, bioprecipitation refers to the nucleation of ice by bacteria in clouds. This process then results in snow or rainfall. Apparently, the sky isn’t a …

Can Gold Be Artificially Made from Common Metals?

Alchemists attempted to purify and perfect certain metals. In 1669, Hennig Brandt was looking for a way to make gold. Instead, he discovered phosphorus. But did you know that we can make gold from common metals with the technology we have available today? Common metals can be transformed into gold by using a nuclear reactor …

What is a Tully Monster?

Experts continue to find more indescribable animal fossils as time pass. Paleontologists were shocked that the now identified Tully Monster was not a worm, as they initially thought, but a soft-bodied vertebrate. The Tully monster, which has remained a mystery for numerous decades, has finally been identified as an ancient vertebrate that lives in bodies …

How Did Evolution Bring Back a Flightless Bird from Extinction?

There are so many reasons why extinction occurs. This could be caused by natural disasters, evolutionary changes, or even overexploitation. But there are instances when certain species seemingly come back.  The Aldabra rail, a flightless bird, was wiped out along with all the terrestrial animals that once lived on Aldabra. A massive flood sank a …

The 2011 earthquake off the coast of Japan was so powerful – measuring almost 9.0 on the Richter scale – it moved Japan 8 feet closer to North America and shifted the planet on its axis, causing the length of a day to shorten by almost 1.8 microseconds

Quake moved Japan coast 8 feet, shifted Earth’s axis (CNN) — The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis. “At this point, we know that one GPS station moved (8 feet), and we …

Neanderthals, which were traditionally thought of as extremely primitive humans, are now believed to have been extremely intelligent, even comparable to the intelligence of modern humans. They used tools, had social structures, thrived in hostile environments, and lived long lives.

Rethinking Neanderthals Bruno Maureille unlocks the gate in a chain-link fence, and we walk into the fossil bed past a pile of limestone rubble, the detritus of an earlier dig. We’re 280 miles southwest of Paris, in rolling farm country dotted with long-haired cattle and etched by meandering streams. Maureille, an anthropologist at the University …

Aroundf 2.1 billion years ago, there existeed several multicellular organisms, that were likely one of the first forays into multicellularity, they coincided with a brief moment of increased oxygen levels and went extinct after the levels dropped, they do not have any modern-day descendants.

Francevillian biota Francevillian biota fossils The Francevillian biota (also known as Gabon macrofossils or Gabonionta) is a group of 2.1-billion-year-old Palaeoproterozoic, macroscopic organisms known from fossils found in Gabon in the Palaeoproterozoic Francevillian B Formation, a black shale province. The fossils are regarded as evidence of the earliest form of multicellular life. The fossils were …

The Scottish Highlands and the Appalachians are the same mountain range, once connected as the Central Pangean Mountains.

Central Pangean Mountains Map of Pangaea, including the Central Pangean Mountains. The Central Pangean Mountains were an extensive northeast-southwest trending mountain range in the central portion of the supercontinent Pangaea during the Carboniferous, Permian and Triassic periods. They were formed as a result of collision between the minor supercontinents Laurussia and Gondwana during the formation …
