But that will hopefully change soon thanks to the largest research on brain cancer of all time. The research was conducted by British and American scientists, who collected genetic data from thousands of people and identified a number of genetic mutations responsible for the aggressive form of cancer.

Black holes collide with unprecedented force

When the LIGO detector first measured gravitational waves four years ago, it was a sensation. The signal came from two black holes that had swallowed each other. Now it appears that this has happened nine times since then. In one case, a new record has even been set for the mass of two fusing black holes.

Bitcoin emits more CO2 than some countries

22 million tons of CO2 per year. That is the emission of computer systems that win bitcoins, according to a study by the technical university of Munich. That is about half the amount of CO2 that countries such as Norway and Ireland emit annually, and more CO2 than for example Estonia, Croatia or Kenya release into the atmosphere every year.

Why are some mountain peaks flat?

Mount Roraima in Venezuela is the most famous example of a table mountain: a mountain with a flat top and vertical flanks. In the local language this type of mountain is called 'tepui', the home of the gods, of which Mount Roraima is by no means the only one. These and the other table mountains in the area are erosion residues, which means that they rise above the landscape because the material around them is eroded 400 meters perpendicularly down on all sides. The Roraima is the largest of its kind in South America with a top of 31 km2 and vertical flanks of 400 meters on all sides.

10 million pumps save the Arctic ice

10 million pumps with wind power have to take seawater from the depth and spray it over the Arctic ice. Here, with the harsh winter cold of -35 to -40 ° C, the seawater will quickly freeze and thicken the waning ice cap. Climate scientists warn that global warming may have disappeared from the North Pole in the summer of 2030 due to global warming, and because of this bleak prospect, a team of researchers from Arizona State University in the US have devised the spectacular rescue plan.

How does rigor mortis arise?

Stiffening muscles in rigor mortis Rigor mortis or corpse stiffness occurs three to four hours after death has started, when the energy depots of the muscles are empty. Muscles need energy to work and contract - but even more so that they can relax. When the body's muscles have used up all their energy, they stiffen in a contraction that we call rigor mortis.

Slime molds are fascinating organisms. They can transport their food along paths, just like ants, and they find their own way. They often take even the shortest route from A to B. And for their reproduction, they create spores in special spore boxes (below on the photo). A spore develops into an amoeba, looks like a crawling mucus and sheds fruit in all sorts of colors.
