Researchers using a fast-aging fish have shown how a common diabetes drug preserves kidney health during rapid aging. The African turquoise killifish, which lives only four to six months, mimics human kidney decline, allowing quick tests of treatments. SGLT2 inhibitors maintained better kidney structures and reduced inflammation in the fish.

Researchers at Wageningen University & Research have recreated enzymes from cannabis ancestors millions of years old, revealing how the plant evolved to produce compounds like THC, CBD, and CBC. These ancient enzymes, more flexible than modern versions, show potential for easier biotechnological production of cannabinoids for medical use. The findings, published in Plant Biotechnology Journal, could lead to new medicinal cannabis varieties.

A new study reveals that intense summer heat in Arizona disrupts honey bees' ability to regulate hive temperatures, leading to population declines in smaller colonies. Researchers observed significant temperature fluctuations inside hives during prolonged heat waves exceeding 40°C. As climate change intensifies such events, the findings highlight risks to bees and their vital pollination role.
