Estimates vary, but the research firm IDC projects that wearable tech will exceed 19 million units this year—more than triple last year’s sales—and will soar to 111.9 million units by 2018. Credit Suisse values the industry at somewhere between $30 billion and $50 billion in the next two to four years.

明年就是这只会说话的萌熊诞生60周年了。为了纪念帕丁顿熊诞生60周年,曾执导2014年口碑和票房都大获成功的电影《帕丁顿熊》的保罗?金回归续集担任导演。在当前这个连儿童娱乐节目都充斥着黑暗和暴力的时代,我们比以往任何时候都需要这种安静地讲述英国普通人生活的片子。这部新电影的情节?事实上,没有太多情节:根据上部电影的结尾,帕丁顿熊现在和温莎花园的布朗一家舒适地生活在一起。他想从一个当地的书商那里给他的姨妈买一本立体书,但发现自己还差几英镑,于是他就穿上了自己的长筒雨靴和粗呢连帽外套,并找到了几份兼职工作——结果却发现这本书在书店被偷了!神秘的破案之旅(其实也没那么严重)就此开始。你在电影中还可以看到关于“橘子酱控”帕丁顿熊的更多笑话。该片将于11月10日在英国上映,11月23日在德国上映,11月30日在柬埔寨和马来西亚上映。(资料来源:欧映嘉纳)

E-cigarettes first started becoming popular in 2012. They work by heating a nicotine fluid to mimic a real cigarette. Their invention is usually credited to Chinese pharmacist Hon Lik, who reportedly created it after he dreamed that he was drowning in a cloud of vapor. His father had died of lung cancer caused by cigarettes. He himself was an unrepentant smoker who had unsuccessfully tried quitting by using a nicotine patch.

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.

No. One way it could play out: after a tentative start involving lots of trading stops, bitcoin futures will slowly begin to attract institutional money.
