A New Kind of Urban Firestorm

Everything around Walker Savage was smoke. Smoke and embers and broken tree limbs and the relentless roar of the wind. Wearing a respirator and goggles from his woodworking studio, he sprayed his garden hose into the gale, hoping to wet the walls and porch of his 99-year-old adobe house enough to keep them from igniting.

But then he saw the flames come surging down the mountain above his home in east Altadena, California: “It was like an avalanche,” Savage said. “But not of snow — it was of fire.”

More than a week later, Savage is still trying to wrap his mind around the Eaton Fire, which killed at least 16 people, destroyed an estimated 7,000 structures and is still only 45 percent contained. The flames moved faster than firefighters could fight them, reaching deep into the suburb to scorch houses well outside the state-designated risk zone.

The Age of Firestorms

Dr. Roslyn Prinsley never imagined that stepping outside her home in Canberra would feel like walking into a smoke-filled abyss. But during Australia’s devastating bushfire season in 2019-2020, even in places untouched by flames, the air was so thick with smoke that breathing felt impossible.

“I asked myself, what are we doing here in the 21st century? We can’t actually go outside and breathe fresh air in one of the cleanest countries in the world,” she remembers thinking. “We can’t let this keep going.”

Dr. Roslyn Prinsley is the Head of Disaster Solutions at the Australian National University’s Institute for Climate, Energy & Disaster Solutions (ICEDS). Finding innovative ways to fight wildfires is part of her daily work – a task that has become more urgent than ever as wildfires grow increasingly frequent in Australia and across the globe due to climate change.

Wildfires are projected to rise 30% by the end of 2050, according to a report by the UN Environment Programme (UNEP) and its partner GRID-Arendal.

One of the recent wildfires in California became the most destructive in Los Angeles history, killing at least 29 people—a number expected to rise—and reducing over 10,000 homes to ash. A perfect set of environmental factors such as long-term drought, preceding heavy rainfall, and hurricane-force Santa Ana winds combined at the worst possible moment.

All of this turned the regular wildfire into what’s called a firestorm.

Inside the L.A. Firestorm

The 2025 LA Wildfires were among the most destructive and costly in U.S. history, driven by a combination of shifting climate patterns and growing development in fire-prone areas. As these types of fires become more common, it raises important questions about how we prepare for and respond to future risks. In this PBS video, experts explore the factors behind the firestorm and what can be done to reduce the impact of similar events going forward.

Mamy Ingabire: Transforming Vector Control in Africa

Mamy Ingabire is an entrepreneur dedicated to using cutting-edge technology to address critical challenges across various industries.

As the Managing Director of Charis UAS, Rwanda’s first licensed drone company, she has played a fundamental role in advancing the use of Unmanned Aerial Vehicles (UAVs) to improve efficiency in vector control, agriculture, construction, mapping, healthcare, and more. Under her leadership, Charis UAS has leveraged drone technology to revolutionize data collection and digital solutions.

Drones vs. Mosquitoes: Fighting malaria in Malawi

In the middle of a muddy field next to a reservoir in north-western Malawi, a team of scientists are hard at work. Boxes of equipment lie scattered around a patch of dry ground, where a scientist programmes an automated drone flight into a laptop perched on a metal box. The craggy peak of Linga Mountain (‘watch from afar’ in the local language) looms over the lake, casting its reflection in the water.

With a high-pitched whirr of rotor blades, the drone takes off and starts following the shoreline, taking photos as it goes. Once the drone is airborne, the team switch from high-tech to low-tech mode. They collect ladles, rulers and plastic containers and squelch through mud until they reach the water’s edge.

The Drone Edge in Vector Control

Achieving global vector control’s potential requires “realigning programs to optimize the delivery of interventions that are tailored to the local context [and]…strengthened monitoring systems and novel interventions with proven effectiveness.” This includes “integration of non-chemical and chemical vector control methods [and] evidence-based decision making guided by operational research and entomological and epidemiological surveillance and evaluation.”

Drones or “unmanned aerial vehicles” (UAVs) can save time and money compared to conventional ground-based surveys. Sophisticated models and monitoring equipment can be purchased for a few thousand dollars. They don’t require a pilot’s license, they are becoming easier to fly, and their paths can be fully automated through AI, machine learning, global positioning systems, and computer vision.

Mosquito Control Drone Application

Check out this video from Calcasieu Parish Mosquito and Rodent Control on how they are using drone technology to spray in hard to reach areas and increase the efficiency of eliminating disease-carrying populations of mosquitos.

A Shining New Age of Vaccines

With vaccines, history repeats itself like music stuck in a loop. On the one hand, advancing technologies create vaccines against a growing list of lethal diseases and conditions. On the other hand, outrageous myths and conspiracy theories compete against science. Familiar and strong emotions run the gamut, from relief when deadly diseases like smallpox are eradicated to anger about perceived dangers to health, governmental overreach and threats to freedom of choice. While religious, commercial, pseudo-scientific and political interests cash in on the confusion, context and meaning are sometimes lost or forgotten. Telling facts apart from misinformation becomes difficult.

Understanding how vaccines are evolving can help better understand both why they are one of medical science’s supreme triumphs and also why the anti-vaccine movement continues to grow and influence so many.

Types of Vaccinations

This infographic from Boston University provides a side-by-side comparison of different types of vaccinations, showcasing their similarities and differences in how they trigger and support the body’s immune response.

Andrew Carnie: Immersing Audiences in Science

Andrew Carnie is a notable contemporary visual artist with a global exhibition footprint, based in the UK.

An emeritus fellow at the Winchester School of Art, Southampton University, Carnie’s work focuses greatly on the intersection of art and science. In fact, he has a blog focused on just that.

While he frequently collaborates with scientists, his creative approach remains broad and unconstrained by specific media, adapting his methodologies to the context and themes of each project.
