The Parasite-Infested Giant African Land Snail is Back in Florida_我的网站

一 | More than 1,000 of the slow-moving creatures have been wrangled in New Port Richey since June 23, when the first one was discovered. The snails not only eat hundreds of types of plants, they also crawl up the sides of buildings and consume the calcium from the stucco and plaster found there before leaving behind their droppings.,"These snails could be devastating to Florida agriculture and natural areas as they cause extensive damage to tropical and subtropical environments," the Florida Department of Agriculture & Consumer Services (FDACS) warned.,Beyond the damage to plants and buildings, the snails carry with them a dangerous threat to humans, too. Rat lungworm (Angiostrongylus cantonensis) most often infect the lungs of rats and other rodents, but can be transmitted through their digestive system. The lungworm larvae is then found in rat feces, which then infect the snails.,Humans can come into contact with the lungworms either by eating undercooked snails, fruits and vegetables contaminated by the infected snails, or consuming undercooked frogs and crabs that have snacked on a sick snail. While the parasite sometimes dies in a human’s central nervous system, other times it can travel through the brain and cause meningitis: a swelling around the brain and spinal cord which can lead to paralysis, comas, and death.,Thankfully, thus far scientists have yet to detect rat lungworm in the snails that have been wrangled in Pasco County, says Greg Hodges, who is an assistant director of the Florida Department of Agriculture’s Division of Plant Industry.,“Let me assure you, we will eradicate these snails. We have done it twice before, and we will do it again – it is not a question of if, but when. Together, let’s locate, communicate, and eradicate, so Florida can again be GALS free,” said Florida Commissioner Nikki Fried.,The state of Florida has set up a quarantine that runs from the northwest corner of the U.S. 19-Ridge Road intersection, and east to Little Road and south to Trouble Creek Road in New Port Richey, Pasco County. In this quarantine area, residents are restricted from touching or moving found snails, as well as plants, soil, compost, and yard waste. Those who do find any other snails are asked to contact state authorities.,At least 30 state employees are searching for the snails and are being assisted by dogs trained to sniff out the invasive critters. Authorities are also using metaldehyde to kill the snails, a pesticide that affects their mucus production and causes lethal dehydration.,The last time Florida dealt with a snail invasion, those giant African snails were dark gray and brown, but now? Authorities are finding the snails to have whiter, cream-colored bodies and dark shells. These newer snails are heavily sought after in the pet trade industry, but in Florida it is illegal to import or own a giant African snail without a permit. However, Florida state authorities have discovered individuals doing just that.。据龙芯中科官方消息，2022年9月初，UEFI官方组织在新发布的UEFI v2.10规范中，全面支持了龙芯处理器的LoongArch64架构，以及部分LoongArch32架构。近期，龙芯团队又完成了LoongArch基础代码与UEFI上游TianoCore EDK2的合并，从而进入其主分支，成为继x86、Arm、RISC-V之后，第四个官方支持的芯片指令系统架构。UEFI即统一可扩展固件接口，是传统BIOS的进化版，是一种PC系统规格，可扩展固件接口、负责加电自检(POST)、联系操作系统、提供连接操作系统与硬件的接口。TianoCore EDK2则是遵守UEFI规范的一个官方代码实现。代码合并有什么意义呢？一是开发者可以直接获取LA基础代码。合并后，开发者可以在开源社区直接获取LoongArch的基础支撑代码，从而直接编译LoongArch的外围驱动，无需再从龙芯获取开发环境。

二 | 二是有助于LoongArch虚拟机开源。虚拟机代码开源以后，开发者或者用户可直接从EDK2社区拿到LoongArch虚拟机代码，编译成功后就可以在业界流行的通用处理器上直接运行LoongArch虚拟机固件，包括LoongArch、x86、x64、AARCH64等。SMBIOS支持LoongArch后，龙芯中科已与多家设备厂家展开联合攻关，打通底层技术链，构建自主创新链。龙芯中科表示，未来将持续关注UEFI、EDK2动向，在TianoCore EDK2上持续贡献、优化LoongArch代码，使LoongArch在EDK2上的实现趋于完善。
