A recent study led by the University of Michigan suggests that Homo sapiens who inhabited Europe around 41,000 years ago may have survived a period of intense solar radiation thanks to technological innovations that seem simple but were highly effective: the use of protective pigments like ochre, the making of tightly fitted clothing, and sheltering […]

The Mysterious “Gravitational Hole” in the Indian Ocean That Makes Sea Level Drop by 106 Meters
In the Indian Ocean, there is a place where the laws of gravity seem to falter—a gigantic depression in the Earth’s geoid where the gravitational force is weaker than normal, causing the sea level to be up to 106 meters lower than the global average. This phenomenon, known as the Indian Ocean Geoid Low, is […]

Twice a Day, Earth’s Surface Rises and Falls: A Lab Detects the Subtle Sway of the Planet
Twice a day, Earth’s surface experiences a slight rise and fall—a phenomenon almost imperceptible to human senses, yet one that reveals a constant dance between our planet, the Moon, and the Sun. This oscillation, known as Earth tide or solid Earth tide, is a direct consequence of the same gravitational forces that cause ocean tides, […]

Why are All Living Beings on Earth Made with the Same Versions of Certain Molecules?: The Mystery of Homochirality
Why are all living beings on Earth made with the same versions of certain molecules and not their mirror images? This is the question that has baffled scientists for decades. A new study published in the scientific journal Symmetry by researcher Michele Fiore explores this enigma and its possible answers, bringing us closer to understanding […]

Oldest Impact Crater in the World Discovered in Australia: A Collision That Changed Earth’s Geology
Imagine a city-sized meteorite crashing into Earth at a staggering speed. That is exactly what happened 3.5 billion years ago in what is now northern Australia, and now, a team of scientists from Curtin University has discovered the traces of this ancient cataclysm, rewriting the history of our planet. The crater is located in the […]

The Explosion of a Supernova Three Million Years Ago Altered Evolution in Africa
Located in a region isolated by mountains along the Great Rift Valley in East Africa, Lake Tanganyika stretches over 600 kilometers and is the deepest lake on the continent. Containing approximately 16% of the world’s available freshwater, this ecosystem has witnessed extraordinary biological events. According to a recent study from the University of California, Santa […]

Scientists Explain What Happened 14 Million Years Ago When the Solar System Passed Through the Orion Star-Forming Region
An international team of researchers, led by the University of Vienna, has revealed that the Solar System passed through the complex Orion star-forming region, a structure linked to the so-called Radcliffe Wave, approximately 14 million years ago. This interstellar journey may have reduced the size of the heliosphere—the protective bubble surrounding our planetary system—allowing greater […]

Polar Ice Caps Are a Rarity in Earth’s Geological History, the Result of a Series of Coincidences, Scientists Say
A new study led by a team of scientists from the University of Leeds has revealed that the cold conditions that have allowed the formation of polar ice caps on Earth are exceptional events in the planet’s history and depend on a complex combination of processes that must occur simultaneously. This research, published in the […]

Scientists Solve the Mystery of Copper and Zinc Scarcity on Earth: Lost After the Planet’s Formation Due to Catastrophic Events and Violent Collisions
For decades, scientists have sought to decipher the mystery of the origin of Earth’s essential elements and the reasons why some of them seem to be missing from our planet. However, a new study sheds light on this enigma and offers an unexpected perspective on the formation of Earth and Mars. A team of scientists […]

Water and Life Arrived on Earth After the Formation of the Moon
A team of researchers led by Katherine Bermingham from Rutgers University in New Brunswick has discovered that water did not arrive on Earth at such an early stage of its formation as previously assumed. This finding has fundamental implications for determining when and how life could have originated on our planet. The study results, published […]
