Most people have fewer sex partners during their lifetime than you might think. Half of all men have slept with only six different women, for half the women the figure is four. Men have twice as many sex partners. The other half is a lot less reluctant, because one in three men and one in five women has had at least 10 sex partners.
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.
WE ARE OBLIGED TO OUR NAME In 1984, Science in the Picture came to the world with one central thought: no subject is too difficult to be exciting and interesting for the curious layman. That thought is still the foundation of our work. Knowledge and insight can indeed be conveyed in an entertaining and interesting way without it being at the expense of the facts and credibility.
So. Women really can do several things at the same time than men. This appears from a new study from Switzerland, and the researchers also think they know why. According to them, the explanation lies in the female sex hormone estrogen, which probably makes it easier for women to use a brain area for several things at the same time.
If nerves are damaged in an accident, it can lead to paralysis or reduced sensitivity. If all goes well, a broken nerve recovers itself very slowly, or a surgeon can intervene. But in both cases, a nerve does not often regain its full functionality. Researchers from Texas have now developed a new method.
A bundle of protons awaits a cruel death. Researchers are pumping more and more energy into the beam with radio waves, which shoots through the narrow tube at almost the speed of light. In another tube - a few centimeters away - an identical bundle swings the other way. When the beams pass through large detectors, the physicists cause them to collide head-on with a force that no other machine on earth can deliver.
If we ever want to take over the solar system, space travel without people is unthinkable. But many scientists prefer that colonization takes place via robots. In 1989 the astronomer Harry Shipman devised a diagram with four scenarios for the future of space travel. According to him, that future is determined by the answer to two questions: 1) Can people live in space?

Remember 500 words in five minutes. Learn a new language in a week. Enumerate thousands of pi decimals. That is daily fare for the best memory athletes in the world, who hold competitions every year in remembering numbers, playing cards, words and faces.

If you open your mouth wide and look in the mirror, you may see the two nut-shaped globules of lymphatic tissue in the back of your throat: the tonsils. Many people have the throat tonsils removed because they are inflamed and swollen. But the tonsils are part of your immune system and catch viruses and bacteria before they enter the body through your mouth and make you sick.
Star Wars, Star Trek and Guardians of the Galaxy - the list of films in which science is taken with a pinch of salt is long. But none of the aforementioned films ended up in the 'worst space films' category when the BBC recently asked a number of NASA employees which space film they found the least.
In our regions we usually do not have to worry about toxic flora and fauna. Yet there are animals that you don't want to pet, and plants that you shouldn't eat. Because along the road, on the seabed and even in your own backyard, you can be painfully injured or fatally paralyzed within a few minutes.
A 300-meter-thick ice plain is about to break in half, allowing an iceberg the size of South Holland and Zeeland to collapse into the sea, west of Antarctica. This is the threatening warning from a group of American and British scientists after seeing a number of new satellite images of a giant crack in the thousands-year-old ice plate named Larsen C.
