Space documentary - The telescopes, open the way to a deeper understanding of nature

Science documentary 2019

A telescope is the primary instrument used for astronomy. A telescope is usually seen as an instrument to increase the image, but the main objective of the astronomical telescope is to collect light.


The telescopes are divided into several types, which differ according to the optical structure. The guiding principle of all types of telescopes is the collection of light by a large optical element and its concentration in a common focus.

Telescopes are also different depending on the type of radiation they are sensitive to. There are telescopes at all wavelengths, from telescopes that absorb radiation emitted from the most energetic sources in the universe - gamma and x radiation, UV-sensitive telescopes, infrared radiation, and radio radiation.

The rule of thumb is that the larger the telescope with the larger optical element, the greater the amount of light it receives.

The telescopes are also distinguished according to their purpose: there are those designated for viewing and for research and photography. Some are designed for viewing planets and are more suitable for viewing pale sky. The telescope's designation is made both by the optical structure of the telescope and by the pedestal on which it is placed and the accessories that can be fitted to it.

Researchers Identified a Virus that Attacks Cancer Cells

Researchers identified a virus that attacks human cancer cells can distinguishes Healthy cells.
Audio Version Of This Post
Viruses are usually supposed to worry us, but this is not the case with inoculate viruses. those that infect cancer cells and kill them, ignoring healthy cells. So it is no wonder that the search for such viruses attracts many researchers.

The Seneca Valley virus.This virus also known as Senecavirus affects pigs and cows. In recent years it has been found that the virus attacks human cancer cells.

The ability to identify tumors and ignore normal cells tested in two trials. The first in relapsed solid tumors in children and the second in lung carcinoma.

Experiments also found that the immune system was removing the virus from the body. Thus preventing it from completing its anticancer action.
Ongoing research to understand how the Seneca Valley virus may be used for cancer treatments.Researchers at the University of Otago in New Zealand discovered in 2017. That the vi…

New study suggests, people with better sense of smell have a better sense of direction

People with a good sense of smell also have a better sense of direction, suggesting a link between the two systems, a new study suggestsWhy do we have a sense of smell?
The smell of fruit directs us (or at least the lemurs) to the most mature fruit, and even our interpersonal relationships are affected by scents. But some researchers believe that its first use by the first animals, the advantage it gave them over the lack of sense of smell, is navigation. 

Now researchers from Canada have shown that people with a better understanding of smell also navigate better.

The olfactory bulb, the region of the brain that receives information about odors from the nose and makes the initial processing of the smell, exists in many species of animals. It has identified in mammals, birds, reptiles, and fish, and there is a similar structure, even in crabs and insects. 

For some, the bulb is tiny compared to the size of the brain, and for others, it is enormous. A study published several years ago showe…

10 Incredible Scientific Breakthroughs and New Inventions

Scientific discoveries continue to appear every year. new discoveries in a variety of fields, from innovative solutions and treatments for common and deadly diseases to archaeological discoveries, space discoveries, and unusual scandals, learn about 10 groundbreaking scientific discoveries that have taken place and can certainly affect our lives in the near future.

1. Sickle cell anemia can be cured by transplantation of stem cellsSickle cell anemia is a severe and common blood disease in which more than 4 million people worldwide are infected.

In April, a pair of scientists at the National Human Genome Research Institute announced that they had completely cured a 26-year-old man with sickle cell anemia, Through the transplantation of healthy stem cells in the body, they hope and believe that similar results will also occur in the future as more patients receive similar treatment with stem cells.
2. Scientists have been able to stop and reverse the process of aging in miceAging is a natu…
