The priorities for food-security research under extreme events

by The Alliance of Bioversity International and the International Center for Tropical Agriculture Asking questions, looking for answers. Credit: CIAT / Neil Palmer Fixing hunger is as challenging as ever. Many food producers, including farmers, hunters and fishers are food-insecure; meaning they’re not always sure where their next meal will come from. More than 50% … Read more

Extreme solar storms can strike out of the blue. Are we really prepared?

A surprise solar storm in 2003 disrupted hundreds of flights all over the world, causing spacecraft controllers to lose track of low Earth orbit satellites for days and cut power to tens of thousands of people in Sweden. Now, nearly 20 years later, one of the world’s leading space weather forecasters admits that our life-giving … Read more

Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal

Credit: Pixabay/CC0 Public Domain Scientists at Queen Mary University of London have made two discoveries about the behavior of “supercritical matter”—matter differences at the critical point where the between liquids and gases seemingly disappear. While the behavior of matter at reasonably low temperature and pressure was well understood, the picture of matter at high temperature … Read more

NASA’s Fermi telescope confirms star wreck as source of extreme cosmic particles

Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just … Read more

Extreme heat waves may be our new normal, thanks to climate change. Is the globe prepared?

Credit: Unsplash/CC0 Public Domain Think the intense heat baking the nation and much of the world this summer seems like an apocalyptic blockbuster? Just wait for the sequel. Already occurring more often, heat waves are forecast to increase in potency and duration because of climate change, say scientists, who fear the globe is ill-prepared to … Read more

Helium-ion-beam nanofabrication: Extreme processes and applications

Providing a helium ion microscope system with GFIS that can be used for extreme nanostructures fabrications with high resolution and sensitivity. Credit: Shixuan He et al Helium ion beam (HIB) technology plays an important role in the extreme fields of nanofabrication. Due to high resolution and sensitivity, HIB nanofabrication technology is widely used to pattern … Read more

Can infrastructure and tourism endure triple-digit temperatures, extreme weather during ‘danger season’?

Samuel Munoz, Assistant Professor in the Department of Marine & Environmental Sciences, says, “We’re going to keep breaking records.” Credit: Alyssa Stone/Northeastern University Elizabeth O’Connell of Northeastern University-London worked through Britain’s record breaking heat wave Tuesday at home with her curtains closed and a Dyson fan at her side. “Regular cold showers are a must,” … Read more

Is the electric grid ready for extreme space weather?

In the early hours of March 13, 1989, the public utility Hydro-Québec went out of service. The entire province of Québec lost power for nine hours, interrupting many aspects of public life for the entire day. Space weather — the conditions in outer space near Earthwhich are heavily influenced by the sun — was quickly … Read more

LA needs 90,000 trees to battle extreme heat. Will residents step up to plant them?

Credit: CC0 Public Domain In 2019, Mayor Eric Garcetti unveiled an ambitious plans to plant 90,000 in Los Angeles by 2021 as part of LA’s Green New Deal. To accomplish this, he appointed the city’s first forest officer, Rachel Malarich, to head the Urban Forestry Division, and authorized a network of nonprofits and “community ambassadors” … Read more
