Deep life's survival secret: Crustal faulting generates key energy sources, study shows
Chinese researchers have recently challenged the long-held belief that "all life depends on sunlight." In a study published in Science Advances, the researchers identified how microbes in deep subsurface areas can derive energy from chemical reactions driven by crustal faulting, offering critical insights into life deep below Earth's surface.

Scientists reveal the mechanism behind sea urchin twinning
Researchers at University of Tsukuba examined how twin organisms can emerge from a single fertilized egg by studying sea urchin embryos. Their findings revealed that when an early-stage embryo is split in half, each portion is able to regenerate its own developmental plan. The team uncovered the dynamic cellular processes and genetic programs that allow each fragment to reorganize and grow into a complete individual.

Study analyzes 400 million years of enzyme evolution
Enzymes catalyze chemical reactions in organisms—without which life would not be possible. Leveraging AlphaFold2 artificial intelligence, researchers at Charité—Universitätsmedizin Berlin have now succeeded in analyzing the laws of their evolution on a large scale.

AI uncovers 'archaeasins,' unique antibiotics from ancient Archaea
They've survived for billions of years in boiling acid, deep-sea vents and salt flats. Now, some of Earth's oldest life forms—microbes called Archaea—are offering a new weapon in the fight against one of today's most urgent health threats: antibiotic resistance.

Scientists develop faster technique to uncover hidden gene switches
Researchers at the Max Delbrück Center have developed a new method to discover how DNA controls genes. Their technique, published in Cell Genomics, can reveal the genetic "switches" that regulate important genes more quickly than existing methods.

Previously unknown protein 'folding factories' discovered
In order to fulfill their many functions, proteins must be folded into the correct shape. Researchers at the University of Basel have now discovered tiny "folding factories" in cells that enable efficient and accurate protein folding. A lack of these structures can lead to diseases such as diabetes and neurodegenerative disorders.

Imaging tech promises deepest looks yet into living brain tissue at single-cell resolution
Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in regions underneath such as the hippocampus. In a new study, a team of MIT scientists and engineers demonstrates a new microscope system capable of peering exceptionally deep into brain tissues to detect the molecular activity of individual cells by using sound.
