With global population growth driving unprecedented infrastructure demand, cement production, a major carbon dioxide (CO₂) emitter, requires sustainable alternatives. A study by Dr Fakhruddin from Hasanuddin University presents a greener concrete mix using sugarcane waste. Results show that Class C fly ash-based geopolymer concrete with 5% sugarcane bagasse ash replacement and polypropylene fibers improved compressive strength by 41% while reducing CO₂ emissions by 25–30% compared to traditional cement.

High concentrations of free fatty acid (FFA) in ketotic dairy cows activate endoplasmic reticulum (ER) stress pathways, contributing to mammary epithelial cell apoptosis and reduced milk yield. The study sets the stage for in vivo trials to validate ER stress inhibitors like Tauroursodeoxycholate (TUDCA) as practical solutions for managing ketosis and enhancing dairy cows health.

New research finds higher temperatures can actually benefit some bumble bee species – particularly those that make subterranean nests. However, periods of extreme heat appear to offset those benefits, and may contribute to declining bumble bee populations in the southeastern United States.
