One Of The Most Significant Microorganisms: Bacteria

-

  What are the microorganisms which play a significant role for humanity? The answer is “bacteria”. They are everywhere, on your mobile phone, on your hand even you wash your hand. 



Approximately 400 million years ago, bacteria existed from really early in life on the earth. Antonie Van Leeuwenhoek is the first human who observed bacteria in 1676, which called them “animalcules”.


Bacteria are single-celled organisms that are complex and really good at surviving in tough conditions. They are categorized into 5 groups according to their shapes:

  • Spherical Bacteria

  • Rod Bacteria

  • Spiral Bacteria

  • Comma Bacteria

  • Corkscrew Bacteria


Lots of people do not know the difference between virus and bacteria. Here is the comparison between 2 of them:



Over 85% of Bacteria are friendly that are quite essential for our bodies. When we are born through the birth canal, lots of mother’s bacteria protect us. Moreover; breast milk contains special ingredients that are meant to be a healthy baby. Approximately 380 million friendly bacteria live in our guts which are called “Bifidobacteria”. These gut bacterias help us to digest the food. Obviously, the immune system is not allowed to kill these friendly bacteria. However, some bacteria create acid that melts our teets. Brushing teeth is key to get rid of these types of bacteria.


According to the brand-new research, swarming bacteria “scream. When they die, they warn neighbouring bacteria are in danger. These screams are not audible, they are chemical alarms.

    Are you ready for your new life? Metaverse is a kind of digital space that represents us and everything. It also refers to online 3-D virtual environments through personal computing using virtual reality devices.      Nowadays, many leading brands such as Microsoft, NVIDIA and Facebook (Meta) are struggling to create a new virtual universe. They are creating tools such as VR, headsets and watches to enhance the feeling of everything.      This new alternative world has several advantages and bright sides. First, we get our avatars like a cartoon characters. Then, we enter the new world. One of the best sides of Metaverse is that we interact with people who aren’t physically near. Moreover, by new virtual reality tools, we will feel people although they are on the other side of the world. Users can also use messaging apps and video calls. A life-like universe allows people to go to a concert and experience a show with other real people inside the Metaverse.      There is a picture f

   Around the world, there are many astonishing and unique animal species. The smallest migrating bird "Hummingbird" is one of them. Hummingbirds are named for the sound they make are one of the great wonders in all of nature. Their wings make the titular "humming" sound they are named for. According to the conducted research, hummingbirds were discovered as fossils in Germany 47 million years ago. Their length is just 10-12 cm and their weight is 18-24 grams. Approximately, the lifespan of hummingbirds is 3-5 years.     Hummingbirds are extremely smart and their brain is larger. They can beat their tiny wings 50-70 times in a second. One of their daily habits is visiting 1000-2000 flowers to drink nectar (that also helps pollination). Their tiny heart pumps the blood 1200 times per minute. They have a very high metabolism that gives rise to eat all day long just to survive.     According to scientists, hummingbirds are special because they have lots

      Biomedical Engineering is a branch of science that deals with medical problems. BME is a complex field which consists of medicine, biology, computer science, and mechanical engineering. Biomedical engineers are basically making artificial limbs, designing the structure to be similar to a normal human organ, and designing the mechanical structure to maintain the best quality for humans.                  One of the earliest basic examples created by Egyptians 3000 years ago because humans needed to develop life-enhancing tools. Years and years, BME has been growing much faster than the average for all occupations from 2012 to 2019. Imagination is one of the significant elements because If you want to create a device, it should be cheaper, faster, and accurate than the other created devices. It is an amazing and inspiring point that If a biomedical engineer creates something, he may save thousands of lives.          A biomedical engineer can create prosthesis, surgical systems/devic
