Kids with autism often “see” the world differently than other kids do. They can have unique experiences of vision, hearing, taste, smell, or touch sensations. These sensory changes are often linked to behavior problems such as isolation, lack of interest, aggression, anxiety, depression, or lack of attention. We thought it would helpful if we could detect behavior problems that might not be obvious yet but are possible in the future. In our study, we used computer programs, based on a type of artificial intelligence called machine learning, to predict possible behavior problems based on how autistic kids receive sensations in their everyday lifes. Our programs analyze the answers to test questions about the way kids perceive the world through their senses, and these programs can then make reliable predictions of behavior problems before they arise. These early predictions allow families and doctors to be aware of and treat those problems early.
自闭症儿童 "看 "世界的方式往往与其他孩子不同。他们会有独特的视觉、听觉、味觉、嗅觉或触觉体验。这些感官变化往往与行为问题有关,如孤僻、缺乏兴趣、攻击性、焦虑、抑郁或注意力不集中。我们认为,如果我们能检测出那些可能还不明显但未来可能出现的行为问题,将会有所帮助。在我们的研究中,我们使用了基于一种名为 "机器学习 "的人工智能的计算机程序,根据自闭症儿童在日常生活中接受感觉的方式来预测可能出现的行为问题。我们的程序会对测试问题的答案进行分析,这些问题涉及孩子们通过感官感知世界的方式,然后这些程序就能在行为问题出现之前做出可靠的预测。这些早期预测可以让家人和医生及早发现并治疗这些问题。

A Sea of Carbon 碳的海洋

There is more to the sea than what you can see! Did you know that when you swim in the sea, you are actually swimming in a soup of carbon? The ocean has many carbon-containing things. Some are large like fish, whales, and shells, but most of them are too small to be seen unless we use microscopes. Some of these minuscule particles are living organisms, while the rest are their remains as they decompose. When land creatures die, they decompose into soil. In the ocean, creature remains are gradually dissolved in seawater. All this dead material contains the element carbon, which, at some point in time, was carbon dioxide in the air. The ocean stores a large portion of the carbon on our planet. In this article, we explain how all this carbon ends up in the ocean and how human activities affect the carbon cycle in the sea.
大海的奥秘远不止你看到的这些!你知道吗,当你在海里游泳时,实际上是在碳汤里游泳。海洋中有许多含碳的东西。有些是大的,比如鱼、鲸和贝壳,但大多数都太小了,除非我们使用显微镜,否则是看不到的。这些微小的颗粒中有一些是活的生物体,其余的则是它们分解后的残骸。陆地生物死亡后,会分解成土壤。在海洋中,生物的残骸会逐渐溶解在海水中。所有这些死亡物质都含有碳元素,而碳元素在某个时期曾是空气中的二氧化碳。海洋储存了地球上大部分的碳元素。在本文中,我们将解释这些碳如何最终进入海洋,以及人类活动如何影响海洋中的碳循环。

What Happens If You Do Not Get Enough Sleep? 睡眠不足会怎样?
Pub Date : 2024-01-03 DOI: 10.3389/frym.2023.1290877

Good sleep is essential for a healthy lifestyle. The official recommendations for the length of a night’s sleep range from 7 to 9 h for adults and 10–13 h for children, depending on age. Based on this recommendation, many children and adolescents around the world do not get the recommended amount of sleep. In this article, we will review the reasons why young people are not getting enough sleep, discuss the effects of lack of sleep on brain function and emotions, and emphasize the benefits of adequate sleep for improving mood and optimizing performance in school. We will also examine how delaying the start of the school day could help increase overall sleep hours and reduce the negative consequences of sleep deprivation.
良好的睡眠对健康的生活方式至关重要。官方建议的每晚睡眠时间,成人为 7 至 9 小时,儿童为 10 至 13 小时,视年龄而定。根据这一建议,全世界许多儿童和青少年的睡眠时间都没有达到建议的水平。在本文中,我们将回顾青少年睡眠不足的原因,讨论睡眠不足对大脑功能和情绪的影响,并强调充足的睡眠对改善情绪和提高学习成绩的益处。我们还将探讨推迟上学时间如何有助于增加总体睡眠时间和减少睡眠不足的负面影响。

Natural Selection From Molecules to Ecosystems 从分子到生态系统的自然选择
Pub Date : 2024-01-03 DOI: 10.3389/frym.2023.1186583
César Marín
There are so many living things on the Earth, including animals, microbes, plants, and fungi. All of this diversity mainly came about from a process of evolution called natural selection. According to natural selection, organisms with helpful traits reproduce more and have more offspring than organisms without those helpful traits. But did you know that natural selection does not just happen at the level of the organism? A theory called multilevel selection explains how natural selection happens at more than one level of life, from molecules to ecosystems. Selfish organisms may do better on their own, but groups of organisms that cooperate with each other can beat selfish groups in the long run. Scientists have proved this theory in labs and in nature, in all kinds of organisms. In this article, I explain the theory of multilevel selection and the evidence that supports it.
地球上有许多生物,包括动物、微生物、植物和真菌。所有这些多样性主要来自于一种叫做自然选择的进化过程。根据自然选择的原理,具有有益性状的生物比不具有这些有益性状的生物繁殖得更多,后代也更多。但是,你知道自然选择并不仅仅发生在生物体的层面上吗?一种叫做多层次选择的理论解释了自然选择是如何发生在从分子到生态系统等多个生命层次上的。自私自利的生物个体可能会做得更好,但从长远来看,相互合作的生物群体可以打败自私自利的群体。科学家已经在实验室和自然界的各种生物体中证明了这一理论。在本文中,我将解释多级选择理论以及支持这一理论的证据。
