How mice extend short-range ultrasound for public announcements

Mice often communicate in ultrasound, which is so high-pitched that it's beyond human hearing. Because these sounds don't travel very far, it was thought that they were only used for private, close-up conversations. New research ...

New method tracks gene expression changes to reveal cell fate decisions

Essentially all cells in an organism's body have the same genetic blueprint, or genome, but the set of genes that are actively expressed at any given time in a cell determines what type of cell it will be and its function. ...

DNA-based neural network learns from examples to solve problems

Neural networks are computing systems designed to mimic both the structure and function of the human brain. Caltech researchers have been developing a neural network made out of strands of DNA instead of electronic parts ...

AI turns simple plant images into early drought warnings, giving crops a voice in the fight against water stress

What if plants could speak when they were thirsty? Agriculture, in essence, is a dialog among crops, soil and climate. Yet drought, the most insidious stressor, remains largely silent until its damage is visible.
