We certainly know a lot of information about viruses, but we still have to learn more about them.
Human discoveries about these microorganisms will never stop, and the following six facts recently discovered in the world of viruses will shock you:
1 – a very old virus in the human brain
According to two studies published in the scientific journal Cell, animal and human brain neurons retain the genetic remains of an old viral infection, which can help us know how our brain processes information.
Scientists have discovered that the ARC, which is found in four-legged animals, is actually the rest of an old virus.
The researchers also discovered that this gene plays a crucial role in the ability of neurons to produce certain types of genetic material and send them to other neurons.
This process shows how neurons exchange information needed for cell reorganization.
Among the functions of the brain, conscious thought and self-concept, both can be possible through this process, which, if not produced, can cause imbalances in nerve synapses or neurons. the unification of neurons, according to the author Annihua Ereberry in a report published by the Spanish newspaper "Espanyol".
2. Viruses literally fall from the sky
During the year 2018, a mystery related to the virus has been solved for a long time, which is why genetically identical viruses can be found at very distant points of the planet.
The reason is that viruses are transmitted by the atmosphere into the air currents.
In a study published in January 2018 in the Multidisciplinary Journal of Microbial Ecology, researchers discovered that viruses can form on water particles and reach the upper layers of the atmosphere, the troposphere, to fall down. in a whole new environment.
3. The controversial relationship between viruses and Alzheimer's disease
According to a study published in the scientific journal Neuron, the theory that viruses could play a role in the development of Alzheimer's disease has been better supported this year.
The authors analyzed about a thousand brain samples reserved in brain stores, including some brains of people with Alzheimer's disease, and noted that levels of two common types of HIV virus Herpes was higher than those of unaffected people.
Although the role of viruses in the development of Alzheimer's disease remains unclear, research suggests a possible link between the disease and the virus.
4. Giant viruses invent their own genes
One of the findings confirmed the existence of "giant viruses", twice as large as ordinary viruses, known to contain a complex genome.
5 – Viral genes can be addictive
Old viral infections can currently play an important role in drug dependence.
In September, a team of researchers, in a study published in the Proceedings of the National Academy of Sciences, revealed that genetic remnants of HC2 were more common among drug users than others.
The remains of this virus have been found in only 5 to 10% of the population, indicating that the viral infection is not very old, that is to say, it goes back 250 000 years .
6. Herpes viruses can be artificially provoked
Anyone with irritable ulcers at the corner of the lips knows what is the herpes virus, an inert virus that fires to cause ulcers.
In October 2017, a team of scientists from the magazine "Plus Pathogenes" showed that the virus could be turned into a state of inactivity and the detection of the proteins that trigger it.
