Your little embryo

You might think that our love of lists could be pinned on the Ten Commandments, but Umberto Eco says otherwise. “The list is the origin of the culture,” he once said on a subject he knows well, having written a book titled “The Infinity of Lists.” And culture wants “to make infinity comprehensible” and “to create order — not always, but often,” hence Homer’s catalogs in “The Iliad” and the roll call of never-completed household chores on my fridge. “We like lists because we don’t want to die,” Mr. Eco also said, which is the best explanation of the listicle that I’ve yet read.
“世界各地的政策制定者认识到美联储的决定将产生什么影响,为此忧心忡忡,这让我们担心,”百达资产管理公司(Pictet Asset Management)全球新兴债券部门主管Simon Lue-Fong表示。“人们在说美联储的决定已被反映到价格上,但既然没人知道究竟会发生什么,这怎么可能呢。”

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.

Men dramatically outnumber women in science, technology, engineering and math (STEM) education and careers, with girls largely losing interest in these topics by age 8. Goldie Blox toys are designed to inspire future engineers by engaging girls in a way that draws on their strong verbal and storytelling skills — while still offering opportunities to build the skills that can later translate into an interest in engineering. And speaking of opportunity, how does a start-up toy company stand out against the big names that have been dominating the toy space since the beginning of time? In a savvy move, Goldie Blox recently released a video that went viral with their take on the Beastie Boys song “Girls.” Though the video was ultimately taken down, Goldie Blox did an excellent job raising awareness of the need to get more women and girls interested in STEM … and of the Goldie Blox toys.
