Bioluminescence Evolved in The Abyss 540 Million Years Ago, Study Finds
24th April 2024 | | Ancient, Animal Life, Earth

In the darkest corners of the planet, where the light of the Sun never touches, eerie glows can yet be found, illuminating the shadows. This is bioluminescence, a remarkable ability that has evolved separately at least 94 times throughout the history of life on Earth. See the study here.

In search for alien life, purple may be the new green
22nd April 2024 | Earth, Humans, Weird

From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth…But an Earth-like planet orbiting another star might look very different, potentially covered by bacteria that receive little or no visible light or oxygen…Instead of green, many such bacteria on Earth contain purple pigments…Cornell scientists report in new research.

Scientists push new paradigm of animal consciousness, saying even insects may be sentient
22nd April 2024 | | Animal Life, Earth, Humans

Bees play by rolling wooden balls — apparently for fun. The cleaner wrasse fish appears to recognize its own visage in an underwater mirror. Octopuses seem to react to anesthetic drugs and will avoid settings where they likely experienced past pain. Nearly 40 researchers signed “The New York Declaration on Animal Consciousness,” which marks a pivotal moment, as a flood of research on animal cognition collides with debates over how various species ought to be treated.

We found three new species of extinct giant kangaroo – and we don’t know why they died out when their cousins survived
16th April 2024 | Ancient, Animal Life, Earth

For millions of years, giant animals or megafauna roamed the lands that are now Australia and New Guinea. Many were like much larger versions of modern animals. There was a four-metre goanna called Megalania (Varanus priscus), for example, which likely ambushed its prey. This beast disappeared by around 40,000 years ago along with almost all the other megafauna aside from remnants such as the red kangaroo and the saltwater crocodile.

Hidden chunk of Earth’s crust that seeded birth of ‘Scandinavia’ discovered through ancient river crystals
2nd April 2024 | | Ancient, Earth

Finland’s river crystals hold clues about the formation of ‘Scandinavia’s’ oldest bedrock 3.75 billion years ago. The analysis revealed that part of the crust is about 250 million years older than scientists previously thought, and that it likely originated in Greenland, according to a University of Copenhagen statement released March 21. See the study here.

Every 2.4 Million Years, Mars Does Something Unexpected to Our Ocean’s Depths
12th March 2024 | | Ancient, Earth, Space

A slow cosmic dance between Earth and Mars has a hidden effect on cycles in the deep ocean. According to a new analysis of the deep-sea geological record, the gravitational interaction between the two planets results in cyclic changes in deep ocean currents that recur every 2.4 million years.
