Science talks (Talk 1)

       

      Let's start the another new phase of explorer G with "science talks". Without wasting any time, let's start with our session 1.

1) China has made the specialized type of spacecraft to bring all the orbit fluctuated satellites to their adequate orbit within the space.

The scope of this invention is to remove the junk from the atmosphere of our earth. There is a bundle of junk satellites which is present in our earth's atmosphere.

2) Beware of your mobile phone if you're using it dynamically, especially at night. 

A recent study by the researchers of Toledo university has found the harmful effects of blue light emitted by the digital devices. Though, most of the mobile phones contain the eye light filter which decreases the effect of the blue light in our eyes. Mainly impact of blue light can cause macular degeneration, a type of disease in which photoreceptor cells of retina get damage due to their high photosensitive property. Other devices like laptops, computers emit blue light which can cause a major risk factor to the user's eyes. especially if you're much aged (50-60 years). It leads to retina damage, study shows.
#Scope: To fight this situation, people can wear dark polarised sunglasses or can use the eye light filter mode consisting of laptops which have been made by Apple.


3) The speed of death of a cell has been measured by the scientists- cell signaling study shows.

During apoptosis process, a kind of self-destruction, of the cell. Scientists analyzed the signaling/ signals/ waves which tend to the apoptosis process in the cell and it's called as programmed cell death (PCD). It's an interesting finding to get rid of cancer like diseases. Apoptosis condition generally caused in cancer to destroy the cancer antigens which are present inside the cell but instead of it, the cell also destroys itself and tends to the tissue devastation. This research can help the cancer patients to fight against such a formidable disease.

4) Don't judge your food state by seeing its expiry date.

Most of us like to have good and healthy food. Often we buy our foodstuff with its long-term storage by analyzing its expiration date. But, I want to tell you that this is not true. The expiration date of foods is only an estimate for its use. According to the research compiled by the Natural Resources Defense Council (NRDC) which is a nonprofit environmental organization, If you've bought a carton of eggs then,  its expiry label can only suggest its best quality time period, not its long-term storage period.

According to a survey, Americans throw up to 40% of purchased food in a year which costs about US$ 218 billion.

[But, what about the Indians, let me know in your comments if you know about it].

So, be sure the next time that your foodstuff is really spoiled or not.

5) NASA has started its mission to touch the sun.

On 12th August 2018, Sunday. Nasa launched a spacecraft named "Parker Solar Probe". It is denoted as a bold mission to the touch the sun. It was launched from Cape Canaveral Air Force Station in Florida. Generally, the initial aim of this spacecraft is to revolve around the Sun's and to send a sun's activity under the extremely high-temperature conditions. Its size seems very small i.e. similar to a small car. MIT's John Belcher discusses this historically approachable launch of Nasa.
