In evolutionary theory, an inherited trait is favored by natural selection when it helps an individual to produce more offspring than its competitors.

From DIY oven cleaner to removing odor from rugs, baking soda, or sodium bicarbonate, has long been known as an essential home cleaning agent.

Other animals besides humans learn to recognize their relatives

Microscopic hydras will trap and paralyze their prey. The next step usually is to stuff their mouths, only hydras usually don't have mouths.

The episode focuses on the flocculation phenomena of ceramic mixtures.

The problem is marked by a progressive aggregation of solid particles and it often takes place due to phenomena of electrostatic attraction between the clay micelles in suspension.

This process leads to a significant increase in viscosity within the system, negatively affecting the proper development of the production process.

The episode offers a general overview about ceramic mixtures, focusing on the corrective action of some specific chemicals, able to develop and trigger an opposite process that provides the ceramic mixture with the proper features, restoring the parameters required for a good development of the process.

With particular reference to the three major mechanisms underlying the deflocculation process:

1. Electrostatic repulsion by cationic exchange
2. 2. Steric repulsion
3. 3. Complexation

Dogs aren't quite as graceful as we humans when it comes to taking a drink. But you might give your pooch more credit if you knew that her lapping method is the most effective one.

When you think of pollination, you probably think of bees buzzing around on a bright summer day.

Insects need water just like the rest of us, so how do they drink?

You might be sitting in your car. Or slouching at your desk. Or hunched over your phone. Take a minute to think: are you comfortable?

A lot of the time phishing is used by people who want to steal your personal information and bank account numbers.

Bonobos, our closest great ape relative, and orangutans, our most distant great ape relative, also appear to be capable of planning ahead.

Are there other ways plants respond to their environments that we just can’t perceive?

There are orchids that smell like rotting meat and orchids that smell like fish to attract pollinators. This one smells like us.

A eureka moment is an experience where a solution or idea suddenly appears in your mind and immediately feels true.

Did you know that researchers have discovered that there are at least 250 kinds of bacteria that live on our skin?

Planetary scientists now have a mountain of evidence, accumulated over decades of exploration, that three to four billion years ago, Mars had accumulations of liquid water on its surface.

Climate scientists need models to help study the impacts of climate change. Feedback loops play an essential role in these models.

Sea turtles try to keep their nests as safe as possible, even leaving behind a decoy.
