This Illustrated Periodic Table Shows How We Regularly Interact With Each Element

The ability to name all of the elements on the periodic table from actinium to zinc is an impressive feat. Actually being able to explain how each element functions in the real world is a little more challenging. If you agree that learning the everyday relevance of all the Earth’s elements is just as important as memorizing their symbols, check out the chart above. This graphic, spotted by inhabitat, presents the information found in a traditional periodic table with pictographs and labels indicating where you might encounter each element in your life.

“The Periodic Table of Elements, in Pictures and Words” was created by Boeing software engineer Keith Enevoldsen. He frames the design as a tool for teaching students in elementary through high school, but it can also be used by adults looking to polish their rusty knowledge from chemistry class. The uses of some elements are widely known: Sodium, for instance, is paired with a picture of a salt shaker, while neon is illustrated with an illuminated advertising sign. Others, though, aren’t so obvious: Did you know that strontium is used in fireworks, or that boron can be found in sports equipment? What about scandium in bicycles, or tantalum in cell phones? There’s a helpful illustration accompanying each element found in nature.

Enevoldsen’s table can also be used to study other facts, like each element’s atomic number and material state (solid, liquid, or gas). The educational resource is available as a set of print-out flashcards and as a full-sized poster available on Amazon for $10.

New Cross-Bred Cosmic Crisp Apples Can Stay Fresh for Up to a Year

Healthy snackers know only too well the disappointment that comes with biting into what looks like a deliciously crisp apple and getting a mouthful of mealy mush instead. It’s just one of the pome fruit’s many potential issues—they also brown quickly, bruise easily, and don’t last as long as whatever bag of chips you might be tempted to reach for instead.

Enter the Cosmic Crisp, a Washington-grown patented hybrid apple that could be the answer to all your apple-related complaints. According to New Atlas, researchers at Washington State University began breeding the new variety as a cross between Enterprise and Honeycrisp apples in 1997, and it’s officially hitting stores now.

Not only does a Cosmic Crisp apple resist bruising and browning better than other kinds of apples, it also boasts an exceptionally long storage life. In a controlled atmosphere, it should stay fresh for a full year—meaning you’ll soon be able to enjoy a crisp, satisfying snack in the middle of March, when out-of-season apples usually leave much to be desired. In your own refrigerator, Cosmic Crisp apples are good for about six months, and they’ll even last for several weeks if you leave them out at room temperature. The long shelf life might cut down on the number of apples that you end up tossing in the trash because they went bad before you got around to eating them.

In a 2012 report published in the American Society for Horticultural Science journal HortScience, the Washington State University researchers found that a group of 114 consumers rated the Cosmic Crisp apple, or WA 38, higher than Fuji apples in sweetness, sourness, flavor intensity, crispness, firmness, juiciness, and overall acceptance. The apple's website even suggests that bakers can reduce the amount of added sugar in recipes that contain Cosmic Crisps.

The Cosmic part of its name comes from the whitish specks on the apple’s skin, which reminded taste testers of a starry sky. In reality, those specks are lenticels—porous openings that allow the apple to exchange gases with its environment.

If you don’t see Cosmic Crisp apples in your grocery store yet, here’s a simple trick for keeping any apples fresh for longer.

The Reason So Many Babies Are Conceived in Winter

Does it feel like many friends and family members announce the pending arrival of a baby during the fall and winter months? That’s not exactly a coincidence. It turns out the cold season is associated with more reproductive activity than any other time of the year. The month of December alone accounts for 9 percent of conceptions in the United States. Science is gaining a better understanding of why.

All living creatures heed an evolutionary instinct to target seasonal births. If conception happens during colder months, babies will be born during warmer months, when resources will be bountiful. Northern states have births peaking in June and July, while southern states come a bit later in October and November. The farther south, the later the birth peak, since people in these warm climates are less influenced by frigid temperatures.

What are frisky humans responding to in colder months? Research suggests that the cooler temperatures and shortened days signal that it's time to get busy. Other theories suggest that men may be more fertile in colder months, or that a woman’s ovum receptivity might change with decreased daylight. Not only are couples potentially more sexually active, but that activity might wind up being more (re)productive.

Are there benefits to conceiving at other times? Possibly. One 2013 study published in the Proceedings of the National Academy of Sciences gathered data from nearly 1.5 million births and found that average birth weight in the first five months of the year decreased by 10 grams. Babies born during the summer months were 20 grams heavier. Mothers who conceived in summer tended to gain more weight than those who conceived at other times.

If you have a disproportionate amount of friends with a September birthday, it’s likely that their parents consciously or unconsciously followed their evolutionary instinct nine months earlier.
