A | 新加坡的9月学校假期即将来临，有了新加坡国庆长假创下54万人次通关记录为前车之鉴，移民与关卡局（ICA）于8月26日发布声明，新马关卡预计将再次迎来大规模堵车和长时间排队！图源：ICA 官网为此，ICA建议旅客预留额外的等候时间，并呼吁旅客配合国际民航局官员的指示，遵守交通规则和车道纪律。对于那些不遵守指示或在检查站违规的旅客，ICA将采取严厉行动。 Mosquitoes use the body odor, heat, and carbon dioxide that humans emit, varying from person to person, to find their next meal. The study, which was published in the scientific journal Cell, reveals that mosquitoes may perceive odors via a variety of distinct pathways, in contrast to animals, which have a single set of neurons that detect each sort of odor.,Female mosquitoes use the variety of odors that people and other animals produce to find the blood that will feed their eggs. The olfactory neurons in the insects' antennae, which are where they take up scents, detect and send scent information to the brain.,Groups of human-odor receptors on the olfactory neurons in the antennae of female mosquitoes (Aedes aegypti) were rendered inactive by the study's lead author Meg Younger and her colleagues at Boston University in Massachusetts using the gene editing tool CRISPR.,"We found that there’s a real difference in the way mosquitoes encode the odors that they encounter compared to what we’ve learned from other animals,” Younger is quoted as saying in the Guardian report on the findings.,According to Younger, the scientists believed that mosquitoes would adhere to the core tenet of olfaction, which states that each neuron expresses only one type of receptor.,“Instead, what we’ve seen is that different receptors can respond to different odors in the same neuron," she added.,This reportedly suggests that mosquitoes can still detect human odors after losing one or more receptors. The researchers asserted that this backup system may have developed as a survival mechanism.,"The mosquito Aedes aegypti is specialized to bite humans, and it is believed that they evolved to do that because humans are always close to fresh water and mosquitoes lay their eggs in fresh water. We are basically the perfect meal, so the drive to find humans is extremely strong," Younger explained,In the end, the researchers argued, knowing how the mosquito brain perceives human odor could be used to influence biting behavior and stop the spread of diseases like malaria, dengue fever, and yellow fever that are transmitted by those insects.,"One major strategy for controlling mosquitoes is to attract them to traps to remove them from the biting population. If we could use this knowledge to understand how human odor is represented in the mosquito antennae and brain, we could develop blends that are more attractive to mosquitoes than we are. We could also develop repellants that target those receptors and neurons that detect human odor," Younger concluded.,Notably, Christopher Potter at Johns Hopkins School of Medicine in Maryland recently found a similar phenomenon in fruit flies, or Drosophila melanogaster.,“If one of these types of olfactory receptors is mutated or no longer functioning, there’s this backup system," Potter is quoted as saying in the New Scientist report. “It’s changing the dogma of what we thought we knew about the olfactory system.”,Science & TechSmell of Blood: Mosquitoes' Scent-Based Host-Seeking Mechanism Revealed16 May, 05:54 GMT。相关阅读：入境兀兰关卡千万别犯这个错！新加坡男子因此被控上法庭！如何更顺畅地通关？在声明中，ICA列出了以下注意事项，以确保旅客能够顺畅通关：确保护照至少有六个月的有效期所有短期访客，包括原则上批准的长期准证持有者，必须在抵达新加坡前三天内，通过MyICA移动应用程序提交附有健康声明的入境卡（SGAC）新加坡永久居民（PR）更新护照后，应在入境前确保再入境许可已转移到新护照上长期准证持有者在再次入境新加坡前，应将护照信息的任何变更通知ICA或人力部遵守禁令，不要携带违禁或管制物品入境，如香烟、口香糖等相关阅读：入境新加坡除了填入境卡，还有这些规定骑机骑车者可用二维码通关对机车骑行者及乘客，ICA鼓励使用二维码通关，这不仅缩短了等待时间，还减少了与移民官员的接触，使通关过程更加便捷和卫生。
