The Amazing Spider: Darwin's Bark Spider

-
   A new insect species of Darwin's bark spider in Madagascar ( we called Caerostris Darwini) -discovered in 2009. When scientists observed this small spider for the first time, they were surprised because of its unusual web.



   Spiders basically have eight walking legs, six or eight eyes, jaws and spinnerets which produce silk. According to fossils, they must have evolved about 400 million years ago and they have over 35.000 species worldwide. However, the Darwin's bark spider which was discovered new, it differs from another spider species. 

    Firstly, tiny and unusual spider has a unique web. Its silk is the toughest biological material ever found in the world because it is ten times stronger Kevlar used for bulletproof vests. This species was named for honours of the father of biology Charles Darwin.

    Matjaź Gregorič says "We hypothesize that this combination was a predisposition for the spider to being able to conquer the unique habitat. No other spider utilizes the air column above open water, so probably, web size and material properties went hand in hand with habitat adaptation."

     Secondly, it can spray a line for crossing a river which is 25 metre. This orb-web bridge consists of silk and fibres. Process is quite simple that it produces unusual big silk into the air that helps to reach its goal. Then, spider strengthens its unique orb web to across easily. After that, it creates a huge trap which can catch 20 insects once. Interestingly, when it makes a mistake to produce web, it eats own web for not waste of its silk.

   Who knows that one day its orb web might help to solve main molecular features for the human race in terms of creating new treatment ways or developing new devices in Biomedical Sciences.

CRISPR For Gene Treatment

Image
             CRISPR is one of the most important developments in the science because it can help to find new treatment ways for genetic diseases.     Every living thing is defined by genes. They tell us how to behave or they basically decide the colour of eyes or hair.    Clustered Regularly Interspaced Short Palindromic Repeats is also known CRISPR was discovered in 1987 by Yoshizumi Ishino.      Scientists got inspired by the immune system of bacteria. This is the natural system that when the virus inside the bacteria, Cas9 protein realise this virus and it gets the virus's RNA genes. Cas9 protein cut the same genes in the target bacteria's genes and paste the virus's RNA genes. When Cas9 protein paste the new genes, it uses "Homology Directed Repair". This process leads to improve the immune system against the virus. Scientists decided to use this process with using Cas9 p...

Vaccines: How They Work and Their Processes

-
Image
   Vaccines are one of the most crucial discoveries worldwide because they are saving many people’ lives.    In 1796, Edward Jenner discovered the first vaccine. He injected materials from a cowpox virus into an eight years old boy to save people from deadly outbreaks of the related smallpox virus and his experiment succeeded. How did this vaccine work?          They are 4 main types of vaccines that are Live-attenuated, inactivated, toxoid, and subunit vaccines. Every type of vaccine is quite simple in terms of process. The process is that: 1- Foreign weak microbes invade the body 2- Our immune system triggers a series of responses  3- Immune system identifies and remove them from the human body 4- B and T cells are fight the microbes and also record information about the microbe 5- Immune system creates the memory about how best to fight them 6- If the same microbe invades the body, our system w...

The War Of The Currents: Nikola Tesla's AC vs Thomas Edison's DC

Image
   Have you ever heard the real story of Nikola Tesla and Thomas Edison? Here is the story of Nikola Tesla who was the genius of science.            On July 10th, 1859 Nikola Tesla was born in Croatia (for our world). He was fascinated with the world and nature. In his early 13, he had the ability to perform integral calculus in his head. He was good in every area of science in high school and finished it early. When he was 21, he had learned 8 different foreign languages.    He was passionate about working really hard. For this reason, the professors wrote a letter to Tesla's father stating that his son may be killed due to overwork. He did not graduate from the university of engineering department for some reasons.     Tesla began working for Thomas Edison's company with studying Direct-Current in 1882. This is the turning point for his life. Edison offered Tesla 1 million US dollars in today's curren...

COVID-19: Background, Infection, Spreading, And Future Guess

-

    This new decade started with lots of disasters such as huge forest fires in Australia and Ukraine, strong earthquakes and more like this. However, a disaster certainly is the worst in 2020 that is SARS-CoV-2 (also known as COVID-19)    COVID-19 is part of the virus family. There are several parts of viruses with this family like SARS and MERS. In 2002-2003, SARS appeared in the world. It infected 8.000 people and killed 800 people. In 2012, MERS appeared like SARS worldwide. It infected 2500 people and killed 900 people.    COVID-19 is a developed version of other old viruses. General idea is that this virus appeared in a wet market in Wuhan with pangolins and bats. Unlike others, it spreads fast and it has 3 types of unusual proteins; Spikes (S) protein, Membrane (M) protein, and Envelope (E) protein. Spikes are really important for this virus because they are used as a key to get inside a cell in our body.       When it g...

Genetically Modified Babies With CRISPR

            Genetically modified babies were born in China with using CRISPR gene-editing technology.    CRISPR is one of the most significant technologies worldwide because, in this way, the human race can find solutions for some problems such as genetic diseases. However, this technology is a really controversial issue because several people believe that this technology can help us. Unlike others, many people say that CRISPR is really dangerous and not ethic for us.              In China, Dr He Jiankui modified twins for reducing their possible HIV infection. For now, both of them quite healthy but we can not know what the future holds because maybe when he is 5, he will have more serious disease than HIV. We have lots of question marks about this issue.    Another experiment is that one married couple's and one woman's genes were used for modifying a ba...

Time Travel Is Possible

   Since many years, the human race has been thinking that time travel is possible. Many films such as "Back to the Future" are based on time travel because If this interesting event is possible, everything will change.        Approximately 100 years ago, Einstein has claimed that gravity can bend the time which is called "Relativity". Slowing down or speeding up depends on how fast you move relative to something. If an astronaut who is inside a spaceship, it age much much slower than a person who is in the earth.    He also said time is four dimensions. Unlike time, space is three dimensions and they are an inseparable part of one thing. According to the physicians, they say that "The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity."    Einstein said that huge gravity affects you in terms of getting a slow time experience. Black holes, neutron stars ...
