Blueberries are touted for their many health benefits—no surprise, considering they pack more antioxidants than any other fruit, according to a 2021 study published inMolecules. But what happens to your body when you eat blueberries daily? Is there a downside to eating too much? Let’s uncover...
Why does water expand when frozen? What happens to molecules during evaporation? What happens to runoff water? What happens to water that does not percolate? What happens when carbon is heated? How did the ice age affect the Earth? When air expands, what happens to the air temperature? When...
What happens to the ice cube? Alcohol is less dense than water, less even, than frozen water, so, since the ice cube is denser than the alcohol in the glass, it sinks. From the book, "Ask a Science Teacher: 250 Answers to Questions You’ve Always Had About How Everyday Stuff Really...
The covalent bonds of water molecules would not be polar, and water molecules would not form hydrogen bonds with each other. Does water expand when frozen? When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After t...
When a planet gets big enough, when it acquires enough mass, it migrates inwards towards the star. Understanding this phenomenon was a real revolution.当一颗行星变得足够大，当它获得足够的质量时，它会向恒星内部迁移。理解这一现象是一场真正的革命。Planetary migration explains why the majority of ...
Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...
The blastocyst trophoectoderm adheres to the endometrial epithelium and is united by the action of the adhesion molecules: integrins β1, β3, and β4, L-selectins, proteoglucans, fibronectins, etc. Embryo adhesion This happens about 7 days after fertilization, when the blastocyst already has ...

Every tiny piece of maltodextrin contains short chains of sugars. After hydrolysis, maltodextrin is purified, then spray-dried to turn it into its signature powder form. While maltodextrin may contain sugar molecules, it doesn’t taste of sugar or sweet. In fact, it doesn’t really have much...
Here again, sugar's chemical construction was instrumental to the outcome. The molten sugar was flung so forcefully and cooled so rapidly that the molecules didn't have time to reorganize as crystals. Cotton candy, like caramel and toffee, is thus called a noncrystalline candy. ...
