直播吧4月21日讯 火箭今日主场85-95不敌勇士，大比分0-1落后。 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。
B | 赛后，火箭中锋亚当斯接受媒体采访，
亚当斯表示，火箭本场面对勇士暴露出的球权保护方面的不足是更大的问题， 勇士利用火箭的失误得到了25分，这削弱了火箭的进攻篮板优势。
C |
“这（进攻篮板）一整年这都是我们的球队特色。我们需要确保做好的另一个特色就是不失误。我们失误越多，他们就会获得更多的进攻机会。在第二节，那就是整场比赛的关键。所以，我们能够通过进攻篮板获得额外的进攻机会并追分，这很好，但是，是的，我们必须解决失误问题。但这绝对很重要。
D | 这就是我们球队特色的一部分。所以，显然，我们不会回避这一点。我们会努力利用好这一优势。”亚当斯说道。
本场比赛亚当斯出战19分钟，4投3中砍下6分12篮板，其中5个前场篮板。
在他的带领下，火箭本场篮板球52-36领先，前场篮板22-6领先。
E | 火箭本场16个失误，勇士11个失误。
