Your little embryo

In an industry enthralled to rehashed stories that strike a familiar chord with audiences, give Pixar credit for often trying something new and pushing their viewers into uncharted territories. Coco, directed by Toy Story 3’s Lee Unkrich, has a visual look based around Mexico’s Dia de los Muertos (Day of the Dead). It’s about a young boy named Miguel who idolises legendary guitar player Ernesto de la Cruz and wants to learn how to play as well as he could. So he goes on a transformative odyssey of self-discovery into the realm of the dead to find his long-deceased idol and learn some lessons about the nature of creativity and originality. Whether it can reach the heights of Pixar’s 2015 masterpiece Inside Out remains to be seen, but Coco should surely be a feast for the eyes. Released November 15 in France, November 22 in the US, Croatia and the Philippines, and November 30 in Israel. (Credit: Disney-Pixar)
Academics appear to be more interested in the cryptocurrency than ever before. There were 190 white papers published on bitcoin in 2014, up from 55 in 2013. Authors—amateur or otherwise—have also flocked to bitcoin: Amazon lists 437 books about or involving the term “bitcoin” published in 2014, compared to 143 in 2013. (That is based on a subject search, and thus includes less hard-hitting titles like Bitcoin Bimbo 3: Undercover Cop Science Fiction Erotica.) And sports fans this year may not have been able to ignore the inaugural Bitcoin St. Petersburg Bowl, a college football playoff game between North Carolina State and the University of Central Florida. ESPN quickly convertedBitPay’s $500,000 rights fee for the game into U.S. dollars.

The "Quarterly Journal of Experimental Psychology" published a study in early 2016 entitled, "The drawing effect: Evidence for reliable and robust memory benefits in free recall." While the title seems a bit long and complex, the study actually demonstrated a very simple idea. Drawing words in picture form helps people make better and stronger memories. The authors of the study created simple tasks where a participant would first draw a simple word, like a common piece of fruit. Later, the authors of the study would ask the participants to recall the words they drew. Other participants in the study were given different tasks like repeating the given word aloud a certain number of times or actually writing the word down. The researchers found that participants who drew doodles of the words they needed to recall fared much better than other participants.

制造业及休闲和酒店服务业应会继续创造就业岗位。美国的工厂是复苏早期的推动者,尽管增长放缓,工厂应该会继续有选择地扩员。继2010年每月增加约9,000个就业岗位之后,今年以来制造业每月增加约1.6万个就业岗位。欧洲、日本和中国经济增长放缓损害了全球贸易流。但最近,更多公司高管开始意识到,在美国制造比在中国等地制造好处更多。与此同时,包括酒店在内的休闲服务业整年都是就业岗位增长的一个可靠来源。[qh]

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.
