Rare sighting of jet from a star-eating black hole

Children diagnosed with brain cancer often die within a year of their initial diagnosis because there are no effective treatments for this rare form of cancer. But by visualizing the cancer cells, researchers have now gained a better understanding of what the tumors look like. The hope is that it will lead to new treatment methods. This is shown by a study with researchers at, among others, Stockholm University and SciLifeLab, recently published in Nature Genetics.
It can be challenging to work if it's below zero. At the South Pole it's about -30 in the summer and -55 in the winter. How do you conduct research in severe cold? Chad Finley is an associate professor at Fysikum and member of the Ice Cube project in the South Pole. - We took turns when we were switching sensors at the telescope. Otherwise both the ice and our hands would have freezed, says Chad who spent three months there in the summer.
