According to Dave Khan, a member of the expedition on the Trakarding-Trumbau glacier system, at night the ice on Everest starts to collapse here and there. The rumbling and scraping is so loud that it is impossible to sleep.

Using sensors that measure the vibrations of the ice masses, the researchers found that extreme cold, the contrast between daytime and night-time temperatures, and climate change in general are responsible for the night-time rumble. The Everest ice is extremely sensitive to these factors.

By sequencing DNA, scientists discovered they were dealing with a member of the genus Hericium. It was given the scientific name Hericium ophelieae, which refers to a Shakespeare poem with lines about ‘long veil’, ‘fair as snow’ and ‘white ghost’. Experts believe that this name perfectly characterises the appearance of the find.

As experts have established, the diameter of this ‘tree’, which stretches for thousands of kilometres, reaches 800 km. The mantle plume has a number of branches, which cause earthquakes in the region.

It is important to understand that mantle plumes and the volcanoes they create are part of a global process that influences the planet’s climate and ecosystem. And whether humanity will survive, according to the researchers, depends on this giant.

How is meat cultured?

Muscle fibres are cultured by taking a piece of tissue, regardless of which animal the sample belongs to. The stem cells in the sample are then treated so that they mature more quickly. As a result, these cells form muscle fibres and edible tissue. Next, however, the endotoxins and waste products, from which most of the emissions originate, must be removed.

The researchers’ conclusions state that the risk of Parkinson’s disease among veterans of the troops at Camp Lejeune was 70 per cent higher than among those who had served at the Marine base in California. The specialists pointed out that the study looked at Americans serving at Camp Lejeune for at least three months between 1975 and 1985.

The scientists say that even veterans who had not been diagnosed with Parkinson’s disease still had an increased risk of experiencing the first symptoms of the disease. The researchers attribute the increased risk of developing the disease to trichloroethylene, found in the water at Camp Lejeune in 1982. The chemical and other hazardous substances were found in the water due to leaks in underground reservoirs, industrial areas and landfills.
