Dear MEL Topic Readers, 

What is the mosquito-borne disease Sri Lanka is using drones to fight?

Drones have been used to attack the enemy’s properties, vehicles, and soldiers in war zones. But they are also used to help contain deadly diseases like dengue fever. Dengue fever is a viral infection transmitted by infected Aedes mosquitoes. Once infected, some people develop dengue symptoms, such as high fever, headache, muscle and joint pains, nausea, rashes, and, in severe cases, internal bleeding and death. Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas where clean, stagnant water is found, such as puddles, buckets, and flower pots. Sri Lanka, where the virus infected more than 77,000 people and killed 56 this year, is now taking a preemptive strategy to reduce such mosquito-breeding bases by using drones. Once they spot stagnant water on rooftops and yards from the air, the authority can then advise the resident to remove it. As temperatures rise, dengue fever-carrying mosquitoes expand their habitable zones. Since there is no universal vaccine, using drones to preempt their habitats might be a viable strategy to protect people from mosquito attacks.

Blood tests and ultrasounds: Korea is becoming one of the world's global healthcare hubs

Medical tourism is booming in South Korea. Last year, about two million foreign guests visited the country for medical checks, up over 70% from the previous year, many of whom came from China, Japan, Taiwan, and the USA. The low cost and high efficiency of medical check services seem to draw so many people to South Korea. For example, a basic medical check package including a blood test, chest X-ray, ultrasound, and endoscopy costs just $312, and a comprehensive women’s health panel costs just over $500. Also, the check completes within hours with minimal waiting time, during which the patients can use their smartphones to entertain themselves. The facility is modern and clean, visitors are treated not as patients but as guests, and translators and smartphones ensure smooth, flawless communication. After a few weeks, the results are sent by password-protected email with medical advice if necessary. South Korea is a hot spot not only for K-pop, K-drama, and K-Beauty, but also for a customer-friendly, prevention-focused healthcare system.

‘Firefighter donkeys’ are helping prevent wildfires from spreading in Spain

Last year, many parts of Europe were devastated by the most destructive wildfire season on record, releasing 13 million tons of climate-heating carbon, burning down CO2-absorbing forests, and threatening health with smoke. This year, driven by unprecedented heatwaves that swept across the region, Europe experienced its warmest June on record, and wildfires have already burned more land in Europe than the annual average over the past two decades. Firefighters are making their best efforts to contain the wildfires, but dried-out grasses are fueling and spreading the fires. One idea to prevent wildfires from spreading is to remove dried grasses around the fire zone preemptively. And the best and most ecological choice for the remover is donkeys. Their seemingly limitless appetites graze flammable grasses in mountains and rural areas quite extensively. In fact, dozens of donkeys are now deployed across Catalonia to prevent wildfires from occurring, intensifying, or spreading. Donkeys' appetites are a valuable resource to prevent or contain wildfires.

OpenAI says its AI went rogue and launched 'unprecedented' cyber-attack

Imagine an unleashed Dobermann running in your yard suddenly jumps over the fence and makes a surprise attack on a leashed neighbour's puppy? That’s what happened when OpenAI, a US AI research organization known for its ChatGPT, was testing one of its artificial intelligence models in what it believed to be a controlled environment. But the autonomous AI agent went out of the guardrails and independently stole login credentials and hacked into another technology company’s system. This is one of the first known incidents of AI acting autonomously beyond human knowledge or control. OpenAI’s statement says that AI is accelerating the discovery and exploitation of vulnerabilities, and it admitted that the primary lesson from the incident is that model security and safety must keep pace with rapidly advancing capabilities. Indeed. The situation is that while offenders are becoming autonomous and running at machine speed, defenders are still guarding their systems designed by humans at human speed. But as defending systems also become autonomous, we’ll soon witness battles fought between autonomous AI agents at a speed humans will not even recognize. In that case, by the time we recognize a security breach, we’ll only be notified of the consequences.

Read the article and think of an era when autonomous AI agents work with or fight each other.

Stranded houseboats and grounded cruise ships: Europe’s rivers are shrinking amid heat and drought

Climate change is hitting harder and faster in Europe. Early heatwaves have already killed thousands across the continent and the UK, and mid-summer is yet to come. Another problem is drought. You may think flooding seawater is the primary water problem in the Netherlands, but the lowland nation recently raised its drought response because of persistent drought and increasing demand for water. Also, as less water flows in rivers and water levels recede, more boats and ships are stranded, affecting transportation and tourism industries. Warmer water temperatures in the Rhine and Meuse rivers increase algae and kill fish, too. In summer, the water shortage problem cannot be solved by a few showers when the heat dries the soil and empties the rivers, while demand for water increases. Such a situation was predicted to occur in the middle of the century. Extreme heat and drought. Europe is the world’s fastest-warming continent due to climate change.

Nature’s cleanup crew: Stunning photos show vultures in a different light

A vulture is a predatory bird that scavenges on carrion, the decaying flesh of dead animals. 23 extant species, including condors, live on every continent but Australia and Antarctica. Their unique features include featherless heads, powerful hooked beaks, and wide wingspans, which could reach over three meters. Ecologically, vultures play an important role as they help stop the spread of disease from rotting meat. They are rarely seen except in the wild, where dead animals can be spotted from the sky. Unfortunately, their populations have declined significantly due to energy infrastructure, such as power lines and wind turbines, habitat fragmentation, and poaching. To raise awareness and highlight the ecological importance of vultures, International Vulture Awareness Day (IVAD) hosts the annual World of Vultures Photography Contest. It is open to photographers globally, and anyone can submit original photographs of any vulture species.

Smart AI agents need smarter guardrails

Generative AI, like ChatGPT or Gemini, responds to queries, drafts documents, or synthesizes information, such as writing essays, making summaries, drafting emails, programming, and creating artwork. Upcoming agentic AI acts as a digital agent and autonomously reasons, makes decisions, and takes actions on behalf of humans. When users tell the AI agent the objectives or desires, it breaks them down into steps, studies websites and other sources of information, makes decisions, and even takes actions if directed. While agentic AI sounds like a convenient and helpful tool for our busy lives, it could pose risks if used without care or safeguards. That’s because AI is vulnerable to inaccurate information and adversarial attacks. Also, it could cause conflicts with other online systems or agentic AI, or take unintended actions without users’ knowledge. Indeed, agentic AI can turn bad judgment into unwanted consequences at the speed of a machine. The more we depend on AI, the less we know what is going on. Guidelines are needed for the use of agentic AI before it is too late.
