The genetics of temperature adaptation: how does life thrive in extreme conditions?

Researchers found that thermotolerant methanogens have smaller genomes with a higher fraction of core genes, while psychrotolerant organisms are enriched in uncharged amino acids. This suggests that temperature adaptation is a gradual process involving fine-scale changes rather than large-scale genome modifications.

U of I study gives a thumbs up to carefully formulated vegan diets for dogs

A University of Illinois study finds that two human-grade vegan diets provide adequate nutrition for dogs, with benefits including lower blood triglycerides and cholesterol. The research also shows positive changes in the fecal microbiome and reduced stool, indicating a potential shift towards improved gut health.

Global population could peak below 9 billion in 2050s

Researchers from the Earth4All initiative project that global population could peak at 8.5 billion people by mid-century with unprecedented investment in poverty alleviation. The team's analysis also suggests that extreme poverty can be eliminated in a generation, leading to a decline in global population trends.
