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.
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.
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.
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.
A symptom of schizophrenia is hearing voices. This can lead to many problems in daily life. Researchers from the Uni-versité de Caen in France may have discovered a button that you can use to turn those votes off. Researchers give brains electrical currents The researchers showed that the voices are silent when the patient's brain is exposed to transcranial magnetic stimulation (TMS).
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.
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.

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.
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.
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.
Underground homes are nothing new. For thousands of years, people have been seeking refuge under the ground, for example to escape the heat or to seek shelter against enemy attacks. Read the article about the 'earth scraper' from Science in Image 5/2013. With the button below you can download it.
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.
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.
1. Laughing disease closed 14 schools OUTBREAK: What initially looked like innocent giggling in a schoolyard, developed in January 1962 into an enigmatic laughing epidemic in Tanzania. The first cases arose in a small village school, where three girls suddenly had to laugh uncontrollably, abruptly and for several hours at a time.
