Scientists have revived their severed pig heads. Their brains functioned without bodies

Experiments to keep the brain working outside the body have so far been carried out in pigs, but scientists say they are in the process of being prepared to conduct them on other animals. Over 100 brains were used in the course of the experiments. They were connected to an external artificial circulatory system and the fluids warmed. Scientists managed to keep their brains alive for over 36 hours.

Someone climbed the Varso Tower, the tallest building in Poland, and showed the panorama of Warsaw

Varso Tower is currently over 220 meters, but will eventually be 310 meters. This will make it taller than the German Commerzbank Tower, 300 meters high, and the British The Shard, 309 meters high. We are talking about total height here. As for the height to the roof, Varso will have 230 meters and 53 floors.

NASA: The Voyager-2 probe is alive and sends greetings from the mysterious end of the world

NASA scientists have been unable to establish a connection with the Voyager-2 probe since January this year. Then there were problems with communication, the device entered the safety mode and did not perform the planned maneuver. The probe was to be rotated 360 degrees to calibrate the magnetic field instrument. This means that the two power-hungry systems were running at the same time, exhausting the available energy resources. This was probably what contributed to the problems.

Denmark wants to be organic. The country is ending offshore oil and gas extraction

Denmark has long talked about the need to fight climate change and reach for solutions that are better for our planet, setting an example for other countries. Even if it means abandoning much of its tradition related to fossil fuels, because, according to the Press Association and Greenpeace, the Danish parliament has just voted to end oil and gas production in the North Sea by 2025. Thus, it cancels and revokes all exploration and production permits in order to complete the mining works that are currently underway in the coming years.

Ocean trenches are the best way to combat plastic in the oceans

The reason we find it difficult to track plastic litter contaminating water bodies is that once it enters the oceans, it is subjected to forces that break it down into tiny fragments called microplastics that measure less than 5mm. As you can easily guess, their monitoring is practically impossible, although new research sheds some light on the matter, showing what role ocean ditches can play in the movement of plastic waste in the oceans. Scientists focused on the Kuril-Kamchatka Riv in the northwestern Pacific, which is 9,750 meters deep, from where eight sediment samples were collected during the 2016 expedition.
