Summary: A global analysis of dietary trends across 101 countries over 60 years reveals that populations consuming more plant-based proteins tend to live longer. While animal-based proteins are linked to lower infant mortality, plant-based sources such as legumes, tofu, and grains are associated with increased adult life expectancy.
After adjusting for wealth and population size, researchers found that countries with high plant protein availability, like India, outperformed nations with meat-heavy diets, like the U.S., in adult longevity. The findings support broader health and environmental goals, highlighting the benefits of shifting toward more sustainable, plant-forward diets.

The judge also found that it violated free speech rights by requiring teachers to use pronouns aligning with a student’s gender identity.
“The First Amendment does not permit the government to chill speech or compel affirmance of a belief with which the speaker disagrees in this manner,” Reeves wrote.

Researchers know the enigmatic clicks made by sperm whales vary in tempo, rhythm and length, but what the animals are saying with these sounds — produced through spermaceti organs in their bulbous heads — remains a mystery to human ears.
Machine learning, however, has helped scientists analyze nearly 9,000 recorded click sequences, called codas, that represent the voices of approximately 60 sperm whales in the Caribbean Sea. The work may one day make it possible for humans to communicate with the marine animals.
The scientists examined the timing and frequency of codas in solitary whale utterances, in choruses, and in call-and-response exchanges between the marine giants. When visualized with artificial intelligence, previously unseen coda patterns emerged in what the researchers described as akin to phonetics in human communication.
