Fuel for thought: Advancing solar-to-fuel technology

As heat waves, floods and wildfires rage and world leaders fret, the climate crisis intensifies.

To date, humans have managed only tentative steps to reduce the output of heat-trapping carbon dioxide (CO2) into the atmosphere. Breaking the impasse of fossil fuel addiction will require bold new technologies, as well as foundational changes to both public and private policymaking.

ASU study shows full decarbonization of US aviation sector within grasp

Every day, 45,000 planes fly across the United States, carrying some 1.7 million passengers. Aviation dominates a frequent traveler’s individual contribution to climate change, and yet it is one of the most challenging sectors to decarbonize. 

The United States is the largest contributor to aviation carbon dioxide emissions in the world and is responsible for more than a quarter of all carbon dioxide emitted from flying.

Army veteran Stephen Bradford once held a skewed view of the world. He saw some “ungodly things in combat,” battled long-term addiction issues, had a marriage go sideways and attempted suicide three times.

“When I came back to the world after combat, I thought the world was messed up,” Bradford said. “But it was really me.”

ASU teams up with Phoenix Children’s and Valleywise Health to study vaccine effectiveness vs. influenza, COVID-19

Modern vaccines against infectious disease have saved hundreds of millions of lives around the world. Although they are the subject of enormous research, many puzzles remain.

 Why do vaccines prevent illness in one individual while failing to provide the same level of protection in another? Which features of an individual’s medical history, immunological makeup, geographical location, age, gender and socioeconomic status contribute to vaccine effectiveness? What causes vaccine aversion in certain communities? How does post-vaccination protection evolve over time?
