In a Warming World, Public Needs to Know More About Protections From Mosquito-Borne Illnesses
The hospitalization last summer of Dr. Anthony Fauci, former head of the National Institute of Allergy and Infectious Diseases, with West Nile virus – and his account of it this week in the New York Times – have helped raise public awareness of the dangers of mosquito borne-illness, which can...
Catastrophically Warm Predictions Are More Plausible Than We Thought
EPFL researchers developed a rating system to evaluate the plausibility of climate model simulations in the IPCC’s latest report, and show that models that lead to potentially catastrophic warming are to be taken seriously.
Scientists cut harmful pollution from hydrogen engines
Scientists have discovered a low-cost method to significantly reduce this pollution from hydrogen internal combustion engines by improving the efficiency of their catalytic converters. The researchers found that infusing platinum in catalytic converters with a highly porous material called Y zeolites greatly enhances the reactions between nitrogen oxides and hydrogen,...
