Experiments suggest that insects have feelings

Emotions are not limited to humans - far from it For those with a pet it's easy to believe that animals have feelings, but it was only 2012 that scientists agreed that animals are sentient beings. It has been found and proven, for example, that dogs are extremely complex and feel human emotions such as envy.

26 Thyroid Cancer Cases Found in Fukushima Children

Another 32 minors in the city had symptoms of the disease. It is too early to know if cases are related to a nuclear accident. WHO says children in the region are at higher risk of developing thyroid cancer. The latest medical tests found 26 cases of children with thyroid cancer in Fukushima City, Japan, although it is too early to know if they are related to the nuclear crisis.

The atomic structure of matter

Since ancient times the human being has been investigating to know more about the matter and to use this knowledge to live better. A very old curiosity is this: Everything that exists is made of matter, but what is matter made of? From the records we have to this day, humanity's earliest answers to the questions posed on the previous page were based on religion and mythology.

Atomic models

How to explain what is invisible? Despite all the sophisticated devices employed in the research and the advanced research on the atom, it remains invisible. The study of the atom is based on models idealized by scientists, that is, hypothetical representations of one's ideas of how the atom is formed.

The table consists of periods and families.

The simple location of a chemical element in the periodic table may already indicate several specific characteristics of that element. Periods Elements are distributed in the table in ascending order from left to right in horizontal lines according to the atomic number (Z) of each element, which is above its symbol.

The foundations in our daily life

Some bases are found in the substances used in our daily lives: magnesium hydroxide (Mg (OH) 2), present in the milk of magnesia used to combat stomach acidity; hydrated lime (Ca (OH) 2), used as mortar in construction; sodium hydroxide (NaOH), used for material cleaning, pipe unclogging and widely used in industry; ammonium hydroxide (NH 4 OH), a component of several commercially available cleaners.

Base function (or hydroxide)

The base function is characterized by substances that have the metal-bound hydroxyl (OH) -1 group. Due to the presence of this group, these substances are also called hydroxides. An example of this function is hydrated lime, used in wall paintings, whose formula is Ca (OH) 2. The bases are formed by ionic bonding of the hydroxyl anion (OH) - with a metal; they are therefore ionic compounds.

Fractional Distillation

It is used in the separation of homogeneous mixtures when the mix components are liquid. Fractional distillation is based on the different boiling points of the mixture components. The technique and apparatus used for fractional distillation is the same as for simple distillation, only one thermometer should be placed in the distillation flask, so that the distillation of the lowest boiling liquid can be known.

The periodic table

Mendeleev and the Periodicity of Elements Dmitri Mendeleev was a university professor in Russia and made an important discovery in the history of science while writing a chemistry book. He recorded the properties of each of the known chemical elements (at the time there were 63; today there are more than 100) on paper cards, each card for one element.

Chemical substances

As you see, the concept of chemical substance - or simply substance, as we will call it from now on - is closely related to the study of chemistry. Chemists consider a substance to be a portion of matter that has well-defined and characteristic properties. Just as you can recognize a friend for a set of characteristics (skin color, voice tone, nose shape, walk, speech, hair color and texture, physical size etc.

Mixture Separation (continued)

Screening: Used when the grains that make up the components have different sizes. Siphonation: It is a process used to separate the phases of the heterogeneous solid / liquid and liquid / liquid mixture. Flotation: is a separation process where the three states of matter - solid, liquid and gas - are involved.

The thermal conduction in everyday life

Since Prehistory, humans have been observing nature and learning from it. Early humans realized that some animals that resist cold well are coated with hair. This is the case with bears and reindeer. This observation must have inspired prehistoric humans to use animal skins to protect themselves from the cold.

Top 10 scientific discoveries that received the most media attention of 2015

As always, science had a great year. There have been many important discoveries and developments, and below you can find the ones that generated the most media attention. 10. Water on Mars The existence of water on Mars has been a subject of constant debate for decades. We already knew that the planet had ice and steam, but the presence of liquid water, while likely, had not yet been established.

Physical States of Matter

Looking at the nature of our planet, we can see that matter comes at room temperature in three physical states. The rocks of the earth's crust are in solid state. In the seas, rivers and lakes, the water is in the liquid state. And our atmosphere is in the gaseous state. Matter is formed by the gathering of mutually attracting particles.

Electric power

You may have noticed on the labels of the appliances or fixtures we purchased that there is a label specifying: 100 (Watt), 500 W, 1000 W etc. But what does this information mean anyway? We saw in mechanics the concept of power: energy / time. The electrical energy that is converted into these devices for various purposes and uses, such as generating motion (motors), generating heat (resistors), generating light energy (lamps), divided by the time in use, is the electrical power, which, As in mechanics, we measure in Watts (joules / second).

Weights and Measures

Ancient peoples standardized hundreds of different weights and measures to meet the needs of their civilizations. The grain of wheat taken from the middle of the ear was probably the first standard weight element. Of the adopted systems, one of them spread throughout Europe and today is still used by the English-speaking countries, after minor modifications: it is the trading system called "AV", French word meaning "heavy goods".

The frictional force

Now think! When a child pushes a toy car on the floor, why does it stop? Should he keep moving forever? The answer is no! The cart would only continue in uniform rectilinear motion forever if the resultant forces acting on it were zero. But it is not.

Chemical reaction

Combustion, an example of a chemical reaction After prehistoric humans learned to master fire, it was found to modify some materials around them. It was possible, for example, to realize that some materials burn and others do not. It has also been found that certain foods, if baked, would taste more pleasant.

Newton and gravitation

A small, battery-powered, straight-line toy car was tied to a line. The other end of the line was tied to a metal ring and was attached to a nail fixed to the center of a board. When the car was started, it was found that instead of going straight, it performed with circular motion.

Mechanics

Imagine you went to the movies. Soon after, a friend asks you to tell him the movie. You will probably explain what has happened throughout history, detailing a few more moments, and then tell the end. Well, kinematics does something similar with the movement of a body. She will describe the movement: how things were at the beginning and throughout the movement, and choose certain moments to gain insight into this phenomenon in more depth.
