The classic question, “What came first, the egg or the chicken?” has intrigued philosophers and scientists for centuries. A recent discovery, however, may finally provide some clarity on this ancient dilemma. In 2017, researchers identified a unicellular species known as Chromosphaera perkinsii, found in oceanic sediments near Hawaii, which could hold the answer. Chromosphaera perkinsii […]

LUCA, the Common Ancestor of All Living Things, Arose 400 Million Years After Earth Formation
An international team of researchers, led by the University of Bristol, has made a significant discovery regarding Earth’s earliest life forms. The study concludes that life began to flourish on our planet only a few hundred million years after its formation. This research focuses on LUCA, the Last Universal Common Ancestor, from which all modern […]
Scientists Create for the First Time Artificial Cells that Behave as if they were Alive
Scientists have made a groundbreaking discovery by creating artificial cells that mimic the behavior of living cells. This significant advancement, detailed in the journal Nature Chemistry, was achieved by Ronit Freeman, a researcher at the University of North Carolina at Chapel Hill (UNC-Chapel Hill), along with her team. By manipulating DNA and proteins—the foundational elements […]
Scientists Reveal how the First Cells on Earth May Have Formed
About 4 billion years ago, Earth started developing the right ingredients for life. Scientists who study how life began wonder what chemicals were present back then. They want to know if the chemistry of early Earth was anything like what living things need today. They do know that spherical blobs of fats called protocells came […]
Researchers Demonstrate that Human Cells “Vibrate”
A research team from the CSIC (Spanish National Research Council) has achieved a significant breakthrough in understanding the mechanical properties of human cells: it has successfully demonstrated that living cells, specifically human breast epithelial cells, exhibit mechanical resonances, a phenomenon previously considered unlikely due to the extraordinary viscosity and complexity of cells in physiological environments.
