Why are scientists dropping mosquitoes from drones in Hawaii?
Hawaii
is home to a unique and diverse array of native bird species, many of which are found nowhere else in the world. However, these birds are facing a significant threat from an invasive species: mosquitoes. According to Vox Media, a drone flying over Hawaii's remote forests is releasing containers filled with live mosquitoes. This approach is aimed at addressing the islands' severe extinction crisis.
Hawaii has lost hundreds of unique species due to invasive species like feral pigs and stray cats. With many native animals on the brink of extinction, scientists are working urgently to preserve what's left.
Extinction crisis of Hawaii's native birds
Hawaii's forest birds, particularly the iconic honeycreepers, are facing a threat from avian malaria, a disease transmitted by non-native mosquitoes. Climate change is exacerbating the issue, allowing mosquitoes to move into higher elevations, further threatening the remaining bird populations. Once thriving with over 50 species, today only 17 honeycreeper species remain, with many driven to extinction.
Scientists are working to save these species because malaria is the primary cause of extinction. Researchers are looking into a novel way to help fight the disease: releasing mosquitoes via drones. A promising step in preserving Hawaii's priceless wildlife is this drone-based solution.
The problem: Mosquito-borne diseases
Early in the 20th century, mosquitoes were brought to the islands. They weren't indigenous to Hawaii. Since then, they have spread rapidly and are now a significant issue for the local birds. Many native bird species are killed by diseases like avian malaria and avian poxvirus, which are spread by mosquitoes.
The impact on native birds of Hawaii
The impact of mosquitoes on Hawaii's native bird population has been devastating. Numerous species are in grave danger of going extinct, including the Palila and the Akikiki. Since these species are unique to Hawaii, their extinction would be devastating not only for Hawaii's ecosystem but also for the entire world.
Conservation efforts
Through a range of strategies, such as habitat restoration, captive breeding initiatives, and mosquito control, conservationists are attempting to preserve Hawaii's native bird population.

GPS steers family into roads flooded by Haw River, man rescues them
HAW RIVER, N.C. (WGHP) — The Haw River rose quickly Sunday night in the wake of Tropical Storm Chantal, and it took many people by surprise. As major roads like the interstate had water flowing over them, navigation systems started suggesting people take alternate routes, but those routes weren't safe either. A family from South Africa traveling to Virginia followed an alternate route down Stone Street Extension, which is a dark, rural two-lane road right over the Haw River. If it weren't for the help of a man who saw them at the right time, they would have been washed into the river. 'We had to make a detour… I never come this way. You don't want to use the words 'divine intervention', but why not?' said Mebane native Bryan Roney. Roney, taking an alternate route himself, knew it wasn't safe to go over the bridge. 'I was attempting to turn around and saw two cars coming this way,' Roney said. He knew the cars were stalled and knew he had to act fast. He got to a man with a little girl first. The man was in shock, gripping his steering wheel. 'I said, 'You got to listen to me. You're fixing to die,'' said Roney. He got them out of the car, and the family of four in the other car. 'The only thing I had was my log chain, so we all grabbed onto this log chain,' he said. And the Haw River nipped at their knees. 'Hold onto this rail, so we held on. We had the chain in one hand, rail in the other,' he said. As the water was rising on the bridge, neighbors in a mobile home park on the riverbank were terrified. 'I looked out, and my entire front steps was floating away,' Kenneth Saum said. Nearby, one trailer was half underwater. Saum checked on his neighbors closest to the river and got devastating news. 'They ended up losing a dog that was still outside,' he said. As daylight broke, waterlines, tree leaves coated in river mud and the washed-out cars were visible. The cars were hauled out Monday afternoon and were total losses. They have their lives and some new clothes. 'I said, 'Let's go to my house.' I called my wife to get some towels ready, and I had a lot of extra shirts, so now that family is all dressed in triathlon shirts, and a family member came from South Boston [Virginia] to pick them up,' Roney said. Roney said the entire ordeal is a good reminder not to depend on GPS in a storm and to back up if you see water over the road, and he's very grateful he was able to help.

'Neighbour called police on me for silly issue – many say I should get revenge'
A lot of people have a few little issues with their neighbours every now and again, but one woman has revealed that her neighbour called the police on her for an outrageous reason Everyone has a few little issues with their neighbours every now and again, however one woman has revealed that her neighbour called the police on her for an outrageous reason. The woman, based in the US, took to Reddit to talk about the situation, as she branded her neighbour a "bored old woman". Explaining things, she wrote: "Our neighbour across the street, Wendy, hates us. I don't know when it started. When we moved in, my husband backed up the moving truck a little too close to her mailbox, I guess. "She sent a message to the previous residents that the new guy living across the street is 'an idiot' - which we know because the previous resident sent that to a different neighbour, whom we befriended." The woman added: "She made a post on our HOA (Homeowners Association) app with tons of screenshots from her door cam of people walking their dogs saying it's illegal for dogs to walk on her lawn. The HOA president commented for her to knock it off." Talking about her current dilemma, she added: "About a year or two ago, my credit card expired and they sent me a new one. Apparently, I put her address instead of mine. There's one number different. 1213 instead of 1212. "Instead of seeing my name on the card and bringing it to me, she called 911 and told them I was trying to steal her identity. The cop knocks on my door and explains, says he told her that's not how it works but she's a 'bored old woman with nothing better to do' and she won't give my card back. I send him back over there to get it - and instead, she shreds it in front of him." She concluded: "There are a lot more stories about her. She's delusional and paranoid and has made problems for everyone on our street, but we mostly all ignore her." The post certainly struck a chord with people, as it racked up more than 4,000 upvotes and hundreds of comments. One person asked: "How old is she? Has anyone considered contacting Adult Services for a mental health check and home inspection? It might be interesting to see if she's deemed unable to care for herself afterward." The original poster replied: "She lives with her husband who seems to be of sound mind so she isn't fully taking care of herself. I'd guess 70s. She's just a busy body." While another added: "Make friends with her husband and then go talk to him." A third chimed in: "The cop calling her a 'bored old woman' is sending me, like even he's over her nonsense. Y'all must have the patience of saints to deal with that While a fourth added: "Plot twist, they return and arrest her for mail tampering, destruction of property and vandalism." Replying to this point, the original poster added: "Yes, messing with my mail was illegal. No, I'm not going to report this crazy old lady. She's miserable enough and I'm not out for revenge."

Agriculture ministers target EU deforestation rules
LISBON – Eighteen EU countries sent a letter to the European Commission on Monday asking for the delay and simplification of rules against deforestation. Third-countries have requested more time to comply with the rules, prompting authorities to suspend the Deforestation Regulation's application until 31 December 2025. The letter refers to the possibility of a further extension of the deadline. In the letter, 18 agriculture ministers argue the regulation overlooks the forest protection standards each country has already adopted and the negligible deforestation risks that some present, imposing 'disproportionate bureaucratic obligations' on them. Forests cover approximately 30% of the Earth's land area, and host around 80% of the world's terrestrial biodiversity. The EU rules are designed to regulate the import and export of products that contribute to deforestation and forest degradation. But the 18 ministers argue that the Commission should include the deforestation rules in its latest deregulation push. They want to see obligations axed in countries where agricultural activity maintains forest cover at significant levels, and in those considered low risk. Signatories included Portugal, Austria, Bulgaria, Croatia, Slovenia, Slovakia, Estonia, Finland, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Poland, the Czech Republic, Romania, and Sweden.
