Eggshell color doesn't indicate taste or superiority

Understanding the biochemistry of ingredients and taste can improve flavor and texture

Keeping eggs at room temperature produces smoother batters when baking, and doing the same with tomatoes helps prevent a mealy, granular mouthfeel. Salting meat a day before gives more time for proteins to break down, improving flavor and tenderness, while cooking vegetables in well-salted water can lock in nutrients and color.

Water is naturally tinted with a slight blue, but sediments and organics can alter its color

The innate coloration comes from water absorbing red light in the visible spectrum more than green or blue, giving shallow waters in some parts of the Caribbean their turquoise hue. If sand is light, it can be churned up by turbulent water, clouding its appearance. Plankton and other organisms can color water by affecting how the rest of the spectrum is absorbed or reflected.

Here’s why genetically identical sisters can have different colored eyes

The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other twin does not? Robin Ball explains how the secret lies in X chromosome inactivation.

What causes high cholesterol?

Cholesterol is a complex health issue, and for a long time, the American Health Association recommended Americans not eat more than three eggs a week to avoid it. But scientific advancements on the impact of different types of cholesterol revealed eggs aren't so bad. So what is it, and how does it effect us? Dive into the digestive tract here.

Traditionally, a glut of unused eggs during Lent would be decorated at Easter

That's how the tradition started, at least in the more orthodox (or strict) branches of Christianity, which didn't eat meat, dairy, or eggs the whole period. By the end, there was more than could be eaten, so decorations ensued.

The color blue is almost never mentioned in ancient Greek literature

Linguists have noted blue is regularly the last color to enter the language of most cultures. Researchers guess that the color's rarity in living organisms is partly the cause of its linguistic absence.

Without liver bile, human poop would be a pale silver color

Stomach acid and enzymes break down food into smaller particles, expelling a semi-fluid mass called chyme into the small intestine, where bile is added. As the intestines absorb nutrients and water, the chyme solidifies and changes color.

Women are born with all the eggs they will ever produce in their lifetime

Girls are born with an estimated 1 million to 2 million eggs in their bodies, but around 10,000 die monthly before puberty. Scientists have not yet figured out why there's such an excessive number of eggs prior to menstruation, but they've calculated that there are roughly 300,000 to 400,000 eggs left at puberty.

Specific imperfections are needed to make Swiss cheese

Impurities in the milk are critical for the formation of holes in Emmental. The cleanliness at farms today could potentially eliminate the iconic characteristic, though cheesemakers are finding a solution to preserve the holes that help define the cheese.

Organic food might be greener, but it’s not better for you

Weighing in on the ongoing debate surrounding organic versus “regular” foods, health experts explain whether organic foods offer significant health benefits. Studies suggest that organic foods have little additional nutritional value compared to...

What's inside an Oreo?

If you look at the ingredient list on your Oreo packaging, you may discover that you don't recognize—or can't even pronounce—some of the listed ingredients, let alone know what they're used for! For instance: Did you know that soy lecithin helps makes oil and water mix? Or that cocoa processed with alkali becomes darker and less acidic? A food scientist breaks down what's inside an Oreo in this seven-minute video.

Private schools don’t inherently boost student performance

High test scores in private schools often reflect affluent, selective student bodies—not superior instruction. Studies show that private school advantages stem largely from socioeconomic factors and admission policies, not institutional quality.

Kids often grow out of allergies to milk and eggs

Between 60% and 80% of kids with allergies to milk or eggs outgrow them by age 16. The immune system doesn’t always recognize and respond to baked forms of these allergens, so when kids eat muffins and other cooked food products, their immune system may become more habituated to them and overcome food sensitivities. Aging out of other allergies is less common.

Color originates from the brain processing light of varying wavelengths

Various geometric models, including Newton's color circle of hue and saturation and the horseshoe-shaped XYZ space for mixing colors via vector mathematics, have been proposed to describe colors accurately. However, these models do not encapsulate the variety of psychological effects that cause perceived colors to differ from mathematical representations.

Just because leftovers look and smell okay doesn’t mean they’re safe to eat

Despite what the sniff test is telling you, older leftovers should probably be trashed. Pathogens that cause illness don’t usually affect the taste, smell, or appearance of food (though if they look bad, you should chuck them as well). Scientists recommend tossing leftovers within a few days even if they appear to be fine.

How house colors can indicate gentrification

Reporters from the Washington Post share an analysis that indicates gray and neutrally toned houses are signs of gentrification in a neighborhood. Visuals of different paint swatches help illustrate which colors are chosen for newly built homes in certain DC districts.

Most flu vaccines are still produced using chicken eggs

For decades, influenza vaccines have been made by growing viruses inside fertilized chicken eggs. Though newer methods using cell cultures or recombinant technology exist, egg-based production remains the primary global manufacturing process.

Ordinary bee larvae can develop into queen bees upon being fed royal jelly

Royal jelly is a protein-rich, yellowish substance produced by worker bees in a honeybee hive. After three days, only a few continue receiving the jelly, which triggers the development of ovaries and other traits not found in workers. The first candidate to emerge becomes queen.

Gold has no nutritional value or flavor—but edible gold is still popular

Gold is a pretty expensive topping. Nonetheless, luxury menus around the world are offering food staples—think bagels, chocolate, and burgers—wrapped or dusted with gold. What's the deal with this fascination?

The Great Salt Lake's distinct dual coloration results from high-salinity organisms that only live in the northern portion and produce a purple protein.

Sir David Attenborough suggested tennis balls be yellow

When you think of tennis, it's the iconic yellow ball, but tennis balls didn't always look like that. This Merchant of Tennis article explores the early tennis balls made from wood in the 1300s, to leather balls, to vulcanized rubber used in the late 1800s. Crucially, Sir David Attenborough worked to broadcast the 1967 Wimbledon Championships in color, leading to tennis balls changing from white to yellow.

How the number of subatomic particles helps identify different types of atoms

Different elements, such as oxygen and nitrogen, can be distinguished by the number of protons in each, since all atoms of the same element have the same number of protons. Isotopes of a given element have the same number of protons but different numbers of neutrons, while ions are atoms possessing different numbers of electrons than protons.

O'Connor raised 40 peacocks, which became symbols for her fiction

O'Connor was drawn to peacocks because of their dichotomy—people were drawn to the beauty of their feathers but turned off by the ugliness of their behavior. It was an apt symbol for her fiction and the birds featured prominently on several of her books' covers.

How the peach became Georgia's fruit, though it makes fewer than other states

After the Civil War, the state sought to redefine its agricultural traditions away from slave-dependent cotton. One innovator, Samuel Rumph, crossed two breeds of peach, resulting in the Elberta, which could travel farther without spoiling. The state embraced this delicious identity to transcend its earlier reputation.
