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.
Researchers at Emory University in the US have discovered that anxiety in mice can pass on to at least three generations. They allowed a group of mice to smell a certain scent, while giving the animals electricity shocks. The mice quickly became scared of the odor, and recoiled from it. Their young showed the same reaction pattern.
"The light is on," cried the Danish physicist Ole Rømer when he discovered in 1676 that the light takes a while to get from A to B. Until then, physicists thought that the light spread immediately, so that the sun's rays could be seen, for example, when they were emitted.
The elephant fish is a favorite of the biologists. The fish has a larger brain than a human - at least in relation to body weight - and has a lot in common with us: he can recognize things, is sometimes bored and can learn to perform assignments. For a reward of course. More striking marine animals Blobvis (Psychrolutes marcidus): is a kind of jelly pudding, because it has almost no muscles and bones.
How do I fall asleep faster? Sometimes you lie under the duvet all night long while your mind wanders and you stare at the lighted figures on the alarm clock. Many people around the world suffer from insomnia, which causes major problems in their daily lives. In addition to the obvious consequences such as less energy and fatigue, a lack of sleep can be harmful to your health and increase the risk of a large number of conditions, including type 2 diabetes and being overweight.
In the Lage Langen, the Messier 47 star cluster is only visible in the middle of winter, when the star sign Stern can be seen in the south above the horizon. Viewed from the earth, Messier 47 is exactly the same size as a full moon. If the circumstances are favorable, the cluster is visible to the naked eye, but binoculars are recommended.
Some natural substances from medicinal plants can kill cancer cells. One is a so-called terpenoid called ingenol-3-angelate, which works against skin cancer. This substance only occurs in the resin of the Euphorbia peplus plant and is virtually impossible to produce in large quantities in the lab.

Every year our planet becomes around 40,000 tons heavier due to small and large meteoroids. The vast majority are so small that they burn in the atmosphere and can be seen as shooting stars. But some meteoroids are so big that the Earth's atmosphere cannot slow them down. These fall through unimpeded and only stop when they reach the surface of the earth.
Charles Darwin nervously bites his nails. It is 1871, and the English natural historian eagerly awaits how his newest theory about sexual selection will be received. Darwin has just published the book The Descent of Man and Selection in Relation to Sex, a sequel to the 12 year old and highly controversial On the Origin of Species.
Fiction: In many books and films, people make long journeys through wormholes. The idea is that strong forces can bend the space, so that areas of the universe that are far apart are still connected. Fact: Wormholes can exist in theory, but how do you keep them open long enough to go through?
Neanderthals treated inflammation and pain with natural medicines. An international research team draws this conclusion in the scientific journal Nature after studying a 50,000-year-old fossilized jaw from northern Spain. Neanderthal cure toothache In a tooth, scientists found plaque, a bacterial layer that can lead to inflammation and cavities in the teeth.
24 Million liters of radioactive cooling water from the Cold War is thawing and threatens to pollute the sea and the ice cap of Greenland. When the US Air Force left Camp Century in the middle of the Greenland ice sheet in 1967, the small nuclear reactor that supplied the base with heat and power for eight years was dismantled.
Originally, the team of scientists at the University at Buffalo wanted to study the mucin-7 protein to find out more about its effect on our health. Mucin-7 is the substance that makes your saliva slimy, and the protein would help rid the body of harmful bacteria. But during the research they came across a mysterious variant of the healing protein.
Moving nitrogen ice New Horizons discovered moving nitrogen ice in the 'heart' of Pluto. On the photo the northern part of this enormous ice plain, which is called Sputnik Planitia. From the winding light and dark patterns you can see that the upper layer of ice is not completely solid, but floats around obstacles and dives into crevasses - just like glaciers on Earth.
