机器人将继承这个地球吗？

当然有可能，因为我们利用毫微技术设计了替换用的身体和大脑，我们将活得更长，拥有更多的智慧，享有至今还想象不到的种种本领。     

電是什么?

在大自然中,電以形形色色的姿態出現。其中最顯著、最普遍的,就是閃電。鄰近北極地帶(如蘇聯的北方)的居民很熟悉這些雄偉的現象:有時候,在夜間的天空上出現了紅、紫、黄、綠各種顏色的寬闊的、明亮的帶子。它們形成火燄般的帷幕,它們離奇地捲起而又展開。這是“北極光”,它的產生就是由於電。在高山上,當空氣相當乾燥的時候,可以看到“電光”。它們表現爲在金屬物體的尖端上的小小的火燄。古     

等待胜利

阿拉斯加湾将会复原，但是复原速速度不会太快。今年3月24日凌晨，埃克森公司的瓦尔德兹号油轮运载着120万桶原油驶向公海，在威廉王子湾的暗礁上搁浅，而阿拉斯加湾从那时起要从生态恶梦中恢复过来得花多长时间呢?该地区的动植物是否能够恢复其原有面貌呢?

Developmental change in the ERP responses to familiar faces in toddlers with autism spectrum disorders versus typical development

Individuals with autism spectrum disorder (ASD) show differences in face processing abilities from early in development. To examine whether these differences reflect an atypical versus delayed developmental trajectory, neural responses to familiar and unfamiliar faces in twenty-four 18- to 47-month-old children with ASD were compared with responses of thirty-two 12- to 30-month-old typically developing children. Results of 2 experiments revealed that neural responses to faces in children with ASD resembled those observed in younger typically developing children, suggesting delayed development. Electrophysiological responses to faces were also related to parent report of adaptive social behaviors for both children with ASD and typical development. Slower development of the face processing system in ASD may be related to reduced self-directed "expected" experience with faces in early development.     

Hemoglobin, growth, and attention of infants in southern Ethiopia

Male and female infants from rural Ethiopia were tested to investigate relations among hemoglobin (Hb), anthropometry, and attention. A longitudinal design was used to examine differences in attention performance from 6 (M = 24.9 weeks, n = 89) to 9 months of age (M = 40.6 weeks, n = 85), differences hypothesized to be related to changes in iron status and growth delays. Stunting (length‐for‐age z scores < ?2.0) and attention performance, t(30) = ?2.42, p = .022, worsened over time. Growth and Hb predicted attention at 9 months, R² = .15, p < .05, but not at 6. The study contributes to the knowledge base concerning the relations among Hb, early growth, and attention.     

Does Felt Gender Compatibility Mediate Influences of Self‐Perceived Gender Nonconformity on Early Adolescents’ Psychosocial Adjustment?

This study evaluated the hypothesis that self-perceived gender nonconformity is distressing to children because it undermines a confident sense of gender compatibility. Participants were 357 early adolescents (180 boys, M age = 12.68 years) in England who responded to questionnaires measuring friendship styles (preoccupied, avoidant), gender compatibility (typicality, contentedness), and adjustment (self-esteem, peer social competence, depression, narcissism). Sex differences in friendship styles indicated that preoccupied and avoidant styles were typical for girls and boys, respectively. Gender-atypical friendship styles predicted poor adjustment, and their impact on adjustment was partially mediated by felt gender compatibility. Results suggest that perceiving gender-atypical attributes in the self undermines adjustment partly because it leads children to feel incompatible with their gender collective.
