CME – Coronal mass ejection – Eruptions on the Sun
CME – Coronal mass ejection – Every second the Sun emits around two million tons of particulate matter – or at least that’s usually the case. In the atmosphere, however, sometimes there are enormous eruptions from the corona (Coronal Mass Eruptions, CME). These types of hurricanes are among the most spectacular phenomena in our part universe . In the process, the Sun loses much more weight than usual. The speed of winds reaches even 10 million / h. CME is a cloud of gas built of electrically charged particles (physicists call it plasma gas). Plasma hurricanes can reach Earth and call the so-called geomagnetic storms that affect electronic devices, causing short circuits and equipment damage.
It is impossible to predict how dangerous it can be for satellites. The Internet and computer-controlled objects, such as nuclear power plants. The last really strong solar storm took place in the telegraph age, i.e. long before the appearance of PCs. Although astronomers are constantly observing the behavior of the Sun, they can anticipate it only slightly ahead of time. This means that in the future we will have at least 24 hours to disable all sensitive systems (even those in nuclear power plants) and secure computers. But geomagnetic storms are not the only problem facing us by the most important star …
Three most common allergies – Causes of allergy development
Three most common allergies – causes of allergy development – Regardless of what causes allergy,
it is always inadequate reaction of the body. Allergy is considered a disease of civilization.
Which affects approx. 20-30% of people, and this number is constantly growing.
Recent studies indicate that the risk of developing allergies carry the genes.
Food allergies: In the food allergy is caused primarily by protein. Allergens work even after heat treatment and after passing through the digestive tract. The spectrum of food allergies is very wide. Mostly allergic to eggs, fish, hazelnuts, milk, celery, fruit, vegetables, flour, peanuts, meat, potatoes and cocoa.
Pollen allergies: This is one of the most common types of allergies. Its occurrence is related to the flowering of plants, whose pollen is the patient’s allergen. Most often they are grass pollen, less common perennial, shrubs and trees. Sometimes the disease persists throughout the year, but during the flowering of the plant. Symptoms such as swelling of the mucous membranes, rhinitis, tearing, and breathing difficulties occur.
Animal allergies: The most common is allergy to cats, dogs, rabbits, hamsters, horses and exotic birds. Allergens in this case are skin or fur. However, allergens can also cause faeces, urine and saliva of animals.
Lake Baikal bottom – Russian mini-submarine Mir–2
Lake Baikal bottom – In July, 2008. Russian mini-submarine Mir–2 reached located at a depth of 1637 m the bottom of the Siberian Lake Baikal. It was the deepest immersion in fresh water in history. Lake Baikal contains 20% of the world‘s fresh water. The lake that formed approx. 20 million years ago, living approx. 1000 unique species of animals and plants. During immersion, scientists collected samples at different depths of the ecosystem so that they could determine the impact of global warming on the lake.
Malignant neoplasm among plants
Malignant neoplasm among plants – They do not, unlike the case of humans and animals – death. Neoplastic changes occurring in plants contribute more to the formation of multiple tumors, growths or deformed bodies. With the cell wall and in the absence circulation is not seen in metastasis of malignant plant cells to other parts of the body.
The main causes of the occurrence of cancer in plants are:
- presence in the genome of the viral or bacterial DNA
- bacterium Agrobacterium tumefaciens that causes tuberosity
