Solar eclipse

6 things you didn't know about solar eclipses

1. Crooked orbit makes solar eclipses rare © Claus Lunau The moon stands at 384,400 kilometers from the earth - while the sun is 400 times further away. Therefore, even though it is a small planet, the moon can completely cover the sun. But the orbit that the moon makes around the earth is a bit crooked.
Medicine

Cancer patients benefit from magic mushrooms

After a serious diagnosis of cancer, anxiety and depression lurk. A paddle trip with psilocybin can then help, in combination with psychotherapy. This is apparent from two American trials with a total of 80 patients. They received hallucinogenic mushrooms under controlled conditions. Doctors strongly advise against experimenting themselves The trip lasted four to six hours and had an immediate and long-term effect.
Monkeys

Can monkeys become people?

Many evolutionary biologists agree that it is possible in principle for monkeys to develop intelligence under the right conditions and over a long period of time that is at the same level as - or even greater than - ours. That scenario appears in, among other things, the science fiction novel De Apenplaneet, which has been filmed several times.

Deceased: Paralyzed genius teased the world for 76 years

He could only move his eyes and one muscle in his cheek. But in his head he roamed the universe, dived into black holes and traveled back to the big bang. Now Stephen Hawking is no longer there. On Wednesday morning the famous mathematician and physicist died at home in the English town of Cambridge.
Animals

The panda must die!

Our earth can easily accommodate ten billion people and at the same time be a safe home for all the animals that currently live there. That is the conclusion of a major investigation. Yet more than 12,000 animal species are threatened. However, this requires a well-considered budget, and an international committee of scientists, economists and other experts has recently drawn it up for the UN.
Body

That way you sleep with your eyes open

It is possible that someone sleeps with their eyes open. However, the sleeper is unconscious and sees nothing. Usually, nerve function in the area around the eye is not working properly, causing the eyelids to slide up. The phenomenon can occur briefly in healthy people and, for unknown reasons, mainly occurs in children.

Intelligence

What is intelligence?

Although some people are clearly more intelligent than others, the concept of intelligence is difficult to define and even harder to understand. Human brains have a unique ability to gain knowledge by drawing conclusions, using the new knowledge to solve problems, to think abstractly and to express thoughts in words.

Can adoptive mother produce milk?

A woman can breastfeed an adopted child, but only with outside help, and it requires a lot of effort. Sometimes the woman can make so much milk that the child can live on it until it passes to solid food. But usually it needs to be supplemented with powdered milk. Prior to adoption, the woman must use a breast pump that stimulates the nipples in the same way as a breastfed child.

Mapping the Atlantic mountain range

In the South Atlantic, nearly 2,000 kilometers southwest of South Africa, a research team from Scripps Institution of Oceanography has mapped a mountain range that we have only known from satellite photos - and whose highest mountain rises 4500 meters from the seabed.

Is swallowing chewing gum dangerous?

No, swallowing chewing gum is not a danger, as long as it does not happen too often. Chewing gum is made from gum with flavors, colors and sweeteners. Some additives, such as sweeteners, are broken down in the stomach and intestinal tract. Despite the extremely acidic stomach contents and efficient digestive enzymes, the body does not break down the gum.

Is all blood red?

Our blood is red because it contains red blood cells that turn red because of the hemoglobin protein. It consists of four almost identical protein chains, each containing a heme group with a central iron atom. Hemoglobin carries oxygen throughout the body. If hemoglobin enters into a connection with oxygen, oxyhemoglobin is the result.

Black flowers and armored toads can thrive at TRAPPIST-1

A cold star with seven small rock planets around it. This is what TRAPPIST-1 looks like. The planetary system, discovered in May 2017, has been named the largest planetary discovery of this decade. The star has three earth-like planets in the habitable zone, where there is a chance of life. A biologist who specializes in animals has made an estimate of the appearance of the alien animals and plants.

Science has spoken: you peak all your life

Youth is incredibly overrated - if you believe a series of scientific studies that have looked at what age we are good at what. Because although there are certainly biological highlights in the childhood and teens, there is also a lot to look forward to when there are more candles on the cake.

Nazi gold

What is the story? When the Second World War came to an end, the top Nazis hid large amounts of gold. For example, transport was en route from the state bank in Berlin to a barracks in the Alps. The gold was hurriedly hidden, including on the Steinriegel mountain. Soon the Americans caught the responsible officers and found 700 gold bars.

Platypus milk contains new weapon against bacteria

Australian researchers charted the structure of a protein in the platypus milk that can help us fight resistant bacteria. The protein curls in a unique way, and that probably determines the antibacterial effect. The bacterial poison in the milk probably developed because the platypus has no nipples, like other mammals.

Will everyone soon have brown eyes?

The genetics of our eye color is complicated. There are certainly three genes involved that code for different pigments. To simplify the answer to the question you can imagine that there is only one gene that controls the eye color and produces brown pigment. This gene is dominant, because a child only needs to get one from its mother or father to make the pigment and therefore have brown eyes.

The solar system came from chaos

The solar system is pretty well organized, but the starting point was chaotic. On the outside, where it was coldest, comets of dust and ice were formed. In the inner solar system it was so hot that water and volatile matter could not exist. The earth and the other inner planets consisted mainly of silicates and metals.

Why do wheels turn backwards in films?

The 'wagon-wheel effect' is an illusion: wheels, propellers and rotor blades seem to stand still or turn backwards in the film. This is because film and TV cameras record 24 or 25 images per second. If the wheel rotates 25 times per second, the camera will always see the wheel in the same position for each frame.
