A half-trained drone crew got the call during Mozambique's worst flood in decades and pulled off zero fatalities

Happy Tuesday. Today's lead is a perfect example of technology doing exactly what it should. In January, the Incomáti River burst its banks in northern Mozambique in one of the worst floods the region had seen in decades. The drone pilots who responded were only halfway through their training. Zero fatalities.

We also have 18,000-year-old Ice Age artists in Ukraine who used the natural growth rings of mammoth tusks as the basis for their designs, a 165-mile bike trail through Minnesota that took 30 years to complete, and a $250 million commitment to help millions of American pets get veterinary care they can't currently access.

Dive in.

In April 2025, the African Development Bank's South Korea-Africa Economic Cooperation Trust Fund launched a program to train 30 public sector experts from Mozambique's meteorology, road mapping, water management, and disaster response agencies in drone-based emergency response. The students were learning not just to fly drones but to operate LiDAR instruments and real-time data platforms capable of streaming imagery of disaster zones. In January 2026, with the course only halfway complete, the Incomáti River burst its banks north of Maputo in one of the worst floods the region had seen in decades.

The government ordered the team to the district. What followed was, as the African Development Bank later described it, the equivalent of a final-year exam. The pilots located stranded families, mapped washed-out roads, and streamed live imagery to rescue crews who had no other way to see what the water had done. LiDAR readings showed exactly how deep each pool of floodwater was, allowing rescue vehicles to navigate safely through door-high water.

"Before this project, I had absolutely no experience with drones," said pilot Kátia Manjate, who learned to run the entire pipeline from data collection to final product under Korean instructors. There were no recorded fatalities among the population, and none among the rescuers. In August, all 30 pilots graduated, with 10 licensed to train the next generation of operators. Local councilwoman Márcia Moiane put it simply: "This project marks a major leap forward — not only in technology but also in how we respond to emergencies. It means we can act faster and smarter, saving more lives."

Eighteen thousand years ago, artists in what is now Mizyn, Ukraine, carved 18 "Venus" figurines from mammoth ivory. New analysis using high-resolution microscopy and 3D digital modeling has revealed something extraordinary about how they worked: the intricate surface engravings were deliberately structured around Schreger and Owen lines, the natural growth rings visible inside a mammoth tusk. The material and the art were inseparable.

The research was made possible by urgent digital preservation work led by Ukrainian NGO Archaic, because the physical artifacts at the National Museum of History of Ukraine in Kyiv are inaccessible due to the ongoing war. Researchers from the UK, Germany, Norway, and Ukraine found that these Eastern European artists were not following trends from Western Europe — they were forging their own independent artistic path.

"This discovery offers an extraordinary window into how Paleolithic peoples perceived and engaged with their material world," said Dr. Aimée Little of the University of York. The findings also challenge the long-held assumption that ancient art simply evolved in a straight line from basic to complex. The analysis revealed a gap of 1,000 to 3,000 years in figurine-making across Europe, coinciding with the coldest peak of the last Ice Age, after which Eastern Europe was first to revive the tradition.

The Mesabi Trail runs 165 miles through the Iron Range of northern Minnesota, from the Mississippi River to the edge of the Boundary Waters wilderness. It connects 28 communities, from Grand Rapids to Ely, passing through a landscape shaped by more than a century of iron ore mining that fueled the American steel industry and the US war effort in World War II. This month, after more than three decades of planning, construction, and fundraising, the last segment was completed.

Much of what makes the trail beautiful was made by industry. The waste heaps from the old mines formed man-made hills that now have forests growing back across them, lining the trail in shade. The project was funded in part by the Department of Iron Range Resources and Rehabilitation, a unique state agency that uses profits from the mines to enrich the communities around them.

"No single organization, funding source, or individual could have built what we see here today," said IRRRB Commissioner Ida Rukavina at the ribbon cutting. "This trail is the product of three decades of partnership and persistence." Historic buildings, mining artifacts, campgrounds, and access to canoeing, fishing, and swimming are all within reach of the trail. In winter, portions open for cross-country skiing and snowshoeing.

Dave Duffield co-founded PeopleSoft, Workday, and Ridgeline. He has given more than $500 million to Cornell University's engineering school and over $300 million to companion animal organizations. He and his wife Cheryl also founded Maddie's Fund, the largest private foundation supporting companion animal shelters in the United States. Their latest commitment takes all of that further.

The Dave and Cheryl Duffield Foundation's "Big Bet for Pets" is a $250 million investment over five years, targeting what the Foundation estimates is a veterinary care gap affecting 50 million dogs and cats nationwide, largely the result of financial barriers that leave millions of pets without routine, preventive, and lifesaving care. Two grant programs launch today: Duffield Boost Grants, offering 250 grants of $10,000 each to nonprofit community vet providers, and Expanding Access Grants, a $10 million pool for established nonprofit clinics ready to scale.

"Pets are members of our families, and they need veterinary care to live long, healthy lives," said Dave Duffield. "For too many families, that care is not easy to find or afford. Big Bet for Pets is our way of investing in a stronger, more accessible safety net for these special animals."

On September 22, 1985, Willie Nelson, John Mellencamp, and Neil Young organized the first Farm Aid concert at the University of Illinois Memorial Stadium in Champaign, spurred by Bob Dylan's comment at Live Aid that summer that he hoped some of the money might help American farmers facing foreclosure. The crowd of 80,000 watched Bob Dylan, Billy Joel, B.B. King, Roy Orbison, John Fogerty, Bonnie Raitt, and Tom Petty perform, and raised $7 million. Willie Nelson had originally thought one concert would solve the problem.

It didn't, and so Farm Aid kept going. The organization lobbied Congress, which passed the Agricultural Credit Act of 1987 to protect farms from foreclosure, and their work is widely credited with helping spark the organic and local food movement. The annual concert continues today, with Dave Matthews now among the board members alongside the original founders.

Every day brings amazing advances and uplifting moments that remind us just how wonderful the world can be. Here are five reasons why today is the best time ever to be alive:

🧬 Fixing DNA One Letter at a Time: CRISPR base editors can now correct individual DNA letters in living cells without cutting the double helix, targeting the single-point mutations responsible for thousands of inherited diseases. Early clinical trials for sickle cell disease and certain forms of blindness are already underway.

🌊 Mapping the Ocean's Hidden Rivers: Fleets of autonomous underwater vehicles are mapping deep ocean currents over thousands of miles, revealing how invisible cold-water rivers distribute heat, carbon, and nutrients across the planet. Understanding these currents is essential to predicting how climate change will reshape global temperatures.

🌱 Banking the Seeds of Future Food Security: Scientists are preserving the wild relatives of major food crops in gene banks worldwide, saving the genetic diversity needed to develop drought-tolerant, disease-resistant, and climate-adapted varieties. These wild relatives carry traits that thousands of years of agricultural selection have bred out of commercial crops.

🪸 Engineering Coral to Survive What's Coming: Scientists are developing heat-resistant coral strains through assisted evolution and deploying them on degraded reefs capable of surviving projected ocean temperatures. Large-scale restoration projects using these adapted corals are now underway in Australia, the Caribbean, and the Pacific.

💡 Power From the Way You Move: Piezoelectric nanogenerators convert the mechanical energy of walking, breathing, and heartbeat into electricity, pointing toward wearable devices and implants that never need recharging. The energy from a single step is already enough to power small sensors.
