  • Emoticons (and some plain old-fashioned punctuation marks) make for rather nice rings. They'll also leave behind a signature mark should you have need to punch someone in the face. 聊天表情(和一些普通的标点符号)也能做成很棒的戒指。要是你要带着这样的戒指揍人的话,我想那人脸上定是充满了微笑。 /201104/133641。
  • Generally, it has been assumed that the need for sleep does not decrease with age, but rather that other factors gradually come to interfere with our ability to sleep through the night.Older individuals, for instance, are at greater risk not only for developing medical and psychiatric disorders but also for taking medications that can disrupt sleep. In spite of these influences, however, it may be that an actual biological deterioration of the sleep drive might also be playing a role.A new study published in the journal Current Biology has been able to shed some light on this puzzle of sleep and aging. The researchers, who wanted to determine the maximal sleep capacity of both young and older persons, arranged for groups of younger adults (ages 18 to 32 years) and older adults (ages 60 to 76 years) to lie in bed for 12 hours during the night and for another 4 hours in the afternoon.The subjects tended to sleep significantly longer at the beginning of the experiment, presumably because they were making up for a sleep debt accrued during their usual daily sleep routines. When the sleep patterns stabilized, however, the younger adults were capable of sleeping for much longer times — an average of 8.9 hours daily — than were the elderly people, who got only 7.4 hours daily. This 1.5-hour difference in maximal sleep capacity is impressive.If your biological drive for sleep seems to have decreased, make sure that you are following the kinds of routines and behaviors that will give you the best chance of getting as much refreshing sleep as possible. Here are some examples of good sleep hygiene:* Make sure that you're going to bed early enough to allow yourself to get an adequate night's sleep.* As your bedtime approaches, develop a relaxing routine in the evening — don't keep busy until the moment before you expect to fall asleep.* Avoid watching TV in bed.* Sleep in a cool, relatively dark room.* Consider going to sleep to the sound of white noise, either from a bedside fan or a machine that generates calming sounds.* Increase your exercising, but don't do it so near to bedtime that it gets your adrenaline flowing and keeps you awake.* Limit your daily intake of caffeinated beverages and avoid them completely after lunchtime.* Avoid alcoholic beverages. 一般来说,假定睡眠所需的时间不会因年龄的增加而减少,而是其他因素逐渐干扰了我们整夜酣睡不醒的能力。老年人,例如,有更大的风险,不仅在不断发展的医疗和精神失调,而且因为药扰乱睡眠。不计这些影响,然而,它可能是一个实际的生物恶化的睡眠驱动器也可以发挥作用。发表在现代生物学杂志上的一项新研究,已经能够阐明睡眠与衰老之迷。研究人员,想要确定年轻人和老年人最大的睡眠能力,安排成组的年轻人(年龄18至32岁)和老年人( 60岁至76岁)夜间躺在床上12个小时,另外下午4个小时。实验开始时试验者的睡眠时间明显偏长,大概是因为他们在弥补日常睡眠期间累积的债务。当睡眠模式稳定下来了,然而,年轻人睡眠的时间更长——平均每天8 .9小时-比老人——只有7. 4小时每天。这1.5小时的最大睡眠能力差异令人印象深刻。如果您睡眠的生物性驱动看起来有所下降,请务必遵循下面的各种惯例和行为,这会给你带来最好的改变,越来越多耳目一新的睡眠。下面是一些好的睡眠保健例子:1.请务必要早点上床,使自己获得足够的睡眠。2.快要睡觉的时候,晚上制定一个相对轻松工作计划——不要忙碌到你希望入睡之前的那一刻。3.避免在床上看电视。4.睡在一个凉爽,相对黑暗的屋子里。5.考虑在无噪声中睡觉,无论是从床头风扇还是机器产生平静的声音。6.加强锻炼,但不是在临近睡觉的时候,因为它会使您的肾上腺素流动,让你清醒。7.控制您每日摄取含有咖啡因(茶精)的饮料,午饭后要完全避免他们。8.避免酒精饮料。 /200811/54706。
  • Children pushed in buggies which face away from their parents may suffer long-term emotional and language problems, according to a study published on Friday.The research, believed to be the first of its kind, found that children who were not facing the person that pushed them were less likely to talk, laugh and interact with their parents compared with those babies that did.The findings were based on a study of 2,722 parents and babies and an experiment where 20 babies were wheeled in buggies for a mile, facing their parents for half the journey and facing away for the other half.Parents using face-to-face buggies were twice as likely to talk to their children while the heart rates of the babies fell and they were twice as likely to fall asleep, an indicator that they were feeling relaxed and safe.Additionally only one baby out of the 20 studied laughed while sitting in an away-facing buggy."Our data suggests that for many babies today, life in a buggy is emotionally impoverished and possibly stressful," said Dr Suzanne Zeedyk, Developmental Psychologist at Scotland's Dundee University who carried out the research."Stressed babies grow into anxious adults."The study, which was published by National Literacy Trust as part of its Talk To Your Baby campaign, found that 62 percent of all children observed travelled in away-facing buggies, rising to 86 percent between the ages of 1 and 2.Zeedyk said it would impact negatively on babies' development if they spent a long time in a buggy which undermined their ability to communicate with their parent at a time when their brain was developing rapidly.Laura Barbour of the Sutton Trust, a social mobility charity which funded the research, said buggy manufacturers should look closely at the findings. 上周五公布的一项研究表明,坐童车背对父母的宝宝今后可能会出现情感和语言方面的长期障碍。研究发现,与在童车里面对父母而坐的宝宝相比,背对父母的宝宝更不爱说笑,也不爱与父母交流。这项研究尚属该领域首次。研究人员对2722对父母和宝宝进行了一项研究,并对20个坐童车的宝宝开展了一项实验。研究人员让父母推着宝宝走一英里的路程,其中半英里让宝宝面向他们,另一半路程让宝宝背对他们。结果显示,使用面对式童车的父母与宝宝交流的几率为背对时的两倍,同时,宝宝的心律有所下降,睡着的几率为背对时的两倍,这表明此时宝宝很放松并有安全感。在参与实验的20个宝宝中,仅有一个宝宝在背对父母而坐时笑了。研究负责人、苏格兰邓迪大学的发展心理学家苏珊妮#8226;兹迪克士称:“我们的研究数据表明,如今很多宝宝的童车生活缺乏情感交流,还可能会感到紧张。”她说:“心理紧张的婴儿成年后更容易焦虑。”研究发现,有62%的宝宝坐背对式婴儿车,而在1岁至2岁的宝宝中,这一比例增至86%。这项研究由英国“全国读写信托”组织发布,是其开展的“与宝宝说话”活动的一部分。兹迪克称,宝宝的大脑发育很快,如果这段时期让他们长时间地坐在阻碍他们与父母交流的童车里,那么会对他们的发育造成负面影响。为该研究提供资金持的“萨顿信托”教育慈善基金会的劳拉#8226;巴伯尔称,童车生产商应密切关注这一研究结果。 /200812/57597。
