  Humans have wrestled with the nature of the universe since time immemorial, but we’ve had science to guide us in recent generations. Most experts on physics and cosmology accept the inflation model, a straight line from the Big Bang to our infinitely expanding universe. However, some scientists hold onto …

An international team of researchers has discovered microbial life, in particular bacterial vegetative cells, in up to 1.2-km-deep and up to 120 degrees Celsius hot sediments in the Nankai Trough subduction zone off Cape Muroto, Japan. A microbial cell (center of the picture) detected from a sediment core sample at …

Aging of Human Cells

scientists-identify-gene-responsible-for-aging-of-human-cells

A gene called GATA6 (GATA binding protein 6) regulates aging of human mesenchymal stem/stromal cells (MSCs), according to new research from the University of Wisconsin-Madison. When mesenchymal stem/stromal cells (MSCs) age, the transcription factor GATA6 is increasingly produced in the cell to induce aging response; by transcription factor-based cellular reprogramming, …
