Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench. The observations from the deepest ocean trench in the world have important implications for the global water cycle, according to researchers in […]

October 5th, 2018 Riffin A new study suggests that plate tectonics — a scientific theory that divides Earth into large chunks of crust that move slowly over hot viscous mantle rock — could have been active from the planet’s very beginning. The new findings defy previous beliefs that tectonic plates were developed over the course of billions of years. […]

September 19th, 2018 Riffin A new analysis is shedding light on Earth’s first macroscopic animals: the 570-million-year-old, enigmatic Ediacara biota. Ediacaran fossils have a slightly bizarre appearance not shared by any modern animal groups. For decades, researchers believed these enigmatic fossils were ecologically simple. However, borrowing a method from modern ecology — fitting species to relative abundance distributions — […]

September 9th, 2018 Riffin Millennia ago, ancient farmers cleared land to plant wheat and maize, potatoes and squash. They flooded fields to grow rice. They began to raise livestock. And unknowingly, they may have been fundamentally altering the climate of Earth. A study published in the journal Scientific Reports provides new evidence that ancient farming practices led to a […]

August 24th, 2018 Riffin The Earth’s building blocks seem to be built from ‘pretty normal’ ingredients, according to researchers working with the world’s most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere.

August 22nd, 2018 Riffin Scientists have found that 4.02-billion-year-old silica-rich felsic rocks from the Acasta River, Canada — the oldest rock formation known on Earth — probably formed at high temperatures and at a surprisingly shallow depth of the planet’s nascent crust. The high temperatures needed to melt the shallow crust were likely caused by a meteorite bombardment around […]

July 23rd, 2018 Riffin A sample of ancient oxygen, teased out of a 1.4-billion-year-old evaporative lake deposit in Ontario, provides fresh evidence of what the Earth’s atmosphere and biosphere were like during the interval leading up to the emergence of animal life.

March 31st, 2018 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A 2-billion-year-old chunk of sea salt provides new evidence for the transformation of Earth’s atmosphere into an oxygenated environment capable of supporting life as we know it. The study by an international team of institutions including Princeton University found that the rise in oxygen that occurred about 2.3 […]

September 12th, 2017 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth. The international team, including palaeontologist from The University of Manchester, found a new set of trace fossils left by some of the first […]
