Skies Begin to Clear for Hydrogen-Powered Flight
The 19-seater Dornier 228 propeller plane that took off into the cold blue January sky looked ordinary at first glance. Spinning its left propeller, however, was a 2-megawatt electric motor powered by two hydrogen fuel cells—the right side ran on a standard kerosene engine—making it the largest aircraft flown on hydrogen to date.

Plant-biomass-based hybrid seed wraps mitigate yield and post-harvest losses among smallholder farmers in sub-Saharan Africa
Structure and composition of BF, OCC and hybrid matrices We created biodegradable matrices without any chemical additives by simply dewatering a slurry of chopped BF (Fig. 1a,b) and OCC (Fig. 1c,d) individually or mixed in various proportions of BF:OCC as follows: BF, BF only; BO82, 80:20; BO64, 60:40; BO46, 40:60; BO28, 20:80; and OCC, OCC…

Burden of the global energy price crisis on households
Overview In this study, we used an environmentally extended multi-regional input–output (EEMRIO) approach to estimate both direct and indirect household energy costs. This model is able to reflect the short-term energy price transmission throughout global supply chains. In the short run, companies and households have only limited options to adjust their consumption patterns and underlying…

Cold-Weather Batteries Get a Boost
While electric vehicles are increasingly popular today, one reason consumers cite for avoiding EVs is the poor cold-weather performance of the batteries. Now, a new study finds, a novel electrolyte for next-generation lithium-ion batteries could help electric vehicles, mobile phones, and other electronics operate and even recharge quickly during extreme freezing temperatures. Potential battery applications…
