University of Utah engineers encode partial differential equations in light and feed them into newly designed optical neural engine, or ONE, to accelerate machine learning.

Complex illnesses are not caused by one gene but groups of genes. The number of gene combinations is too enormous to analyze comprehensively. New AI model focuses on gene expression changes to identify key genes and their collective influence on disease.

Researchers studied an ancient forest of bald cypress trees preserved in subfossil form at the mouth of Georgia’s Altamaha River. Using radiocarbon dating and tree-ring analysis, they revealed a dramatic shift in growth patterns: around 500 A.D., these trees began growing faster – but living far shorter lives. Their average lifespan plunged from more than 470 years to just 186, coinciding with the Vandal Minimum,  a sixth century climate crisis marked by global cooling and upheaval, likely caused by volcanic eruptions and possibly even a comet impact.
