Baby pufferfish inherit a chemical defence from their mothers to ward off predators

Researchers have discovered that female pufferfish pass a nearly non-toxic chemical on to their larvae. The compound makes the young fish unappetizing to would-be predators, boosting their odds of surviving early life. Interestingly, the same chemical also draws other pufferfish toward it. This dual function appears to support the species' survival strategies during its most vulnerable stages.

16-year-old Vedant Thakker builds free app to flag wildfire risk for Californians

Vedant Thakker, a 16-year-old, has developed a free application called Red Flag Check. The tool assesses wildfire danger using data from the National Weather Service. It sorts residential locations under red flag warnings into four distinct risk levels. The app is intended to give local residents clearer information about their exposure. It is designed with older adults in mind, who may be more vulnerable during wildfires.
