CRISPIR


Introduction 

            Today we are going to learn about CRISPIR. So let's roll and learn about it!

What is CRISPIR?

                                                CRISPIR is nothing but editing DNA. 

What is Cas9 and how does it work?

Cas9 is a protein. Let's say yellow fever enters the body and body makes the protein Cas9. Now the body has faced yellow fever before and it has a fragment of the virus' DNA. It creates the Cas9 protein and puts the fragment of viral DNA in the protein. Then the body leaves it to go on patrol. So Cas9 like "scans" every "invader" DNA in the body with the fragment it has. Then snip snap it cuts the DNA. In other words Cas9 patrols the body until it finds an "invader" with the DNA fragment Cas9 has. If that is still complicated for you, click on the word NOVA in my bibliography. This may be not a real situation but the scenario shows how Cas9 works.

How is Cas9 related to CRISPIR?

Let's say we have a DNA strand here. The strand is AGTAGTAGTAAACGTA. Do you recognize a pattern here? I do. The pattern is AGTA. But there's also some letters between the 1st AGTA and the 2nd AGTA. Those letters are called spaces. Now let's say that Cas9 bumped into our DNA strand and was looking for the fragment AC in our strand. So it cuts it and now the DNA strand has changed. CRISPIR is all about changing DNA, right? So that's how Cas9 is related to CRISPIR.


The positives of CRISPIR

CRISPIR can treat diseases such as sickle cell and cancer. Parents can also use CRISPIR to customize a child's traits so that they like the child. CRISPIR can also be used so that people with old age can still live for a few years. These are all positives of CRISPIR.

  The negatives of CRISPIR

We can go too far with CRISPIR. For example, we can use it to change embryos, but that means the changes can be passed on from generation to generation. That is one negative of CRISPIR. If you want to learn more, please go to my bibliography.

A tribute to Mother Nature

I want to thank Mother Nature because she created us and CRISPIR. Then we discovered it.

So, I guess that's that. Buh Bye!

Mars

Today, in this section of my blog, we are going to learn about Mars .  Once Mars had more water than the Artic Ocean. Scientists found bacteria, meaning signs of life. 1/2 the size of Earth. 1st place winner of the discovery of Mars is Galleo Gallei. Atmosphere mostly has got in store: CO2. 49 Ton miles separated from the Sun. 1 Mars year = 687 Earth days Temperature around -195 degrees F 1Mars day = 24 Earth hours and 39 Earth minutes. 1st Mars Rover: Sojuner Toxic surface Mars dust breaks electronics Colder than Earth. Super thin atmosphere. So many rovers sent. 0% magnetic field. Scientists are thinking to send human beings to the planet. Named after the Roman God of war. So, dear viewers, these points should have given you a start about the information scientists are learning about Mars.  Additional weblinks below. https://kids.kiddle.co/Mars https://spaceplace.nasa.gov/all-about-mars/en/

Helping hummingbirds!

Hi there! My full name is Shreyas Akula. I'm 8 years old. Please go to the end of the blog, ( not the comments) to click on the essential links. Did you know that plants don't produce their fruit all by themselves? Animals help plants produce fruit ! These animals are called pollinators . But in this era of human history, our activity is putting these animals into trouble ! Wait a second. You might not know what are pollinators are. So let's find out ! Pollinators transport pollen from flower to flower. Pollen carries the male reproductive  cells of the plant. How do pollinators transport pollen? Well, that's no problem for pollinators 'cause they are small! Okay, we are zooming into a flower! The pollinator, a bee has arrived! First, the bee goes to the middle of the flower. This part is called the stigma and located in the middle of a flower and is female. While making it's journey to the stigma, it bumps into the pollen dusters. If you you combine the anther ...

Microsoft's Majorana 1: A Leap Toward Practical Quantum Computing

  In February 2025, Microsoft unveiled a groundbreaking advancement in quantum computing: the Majorana 1 chip. This development marks a significant step toward realizing practical, large-scale quantum computers. What Is the Majorana 1 Chip? The Majorana 1 chip is Microsoft's first quantum processing unit (QPU) designed to harness topological qubits. Unlike traditional qubits, which are susceptible to errors due to environmental noise, topological qubits are inherently more stable. This stability arises from the use of Majorana zero modes—quasiparticles that are their own antiparticles and are theorized to exist in certain quantum states. To create these topological qubits, Microsoft introduced a new class of materials known as topoconductors . These materials combine indium arsenide (a semiconductor) with aluminum (a superconductor) to achieve a state called topological superconductivity. When cooled to near absolute zero and exposed to specific magnetic fields, these materials...
