here are 20 images made by science you won’t believe are real - types of die casting

There is no doubt that, year after year, we have achieved new scientific achievements.
Photography is one of the most important areas of scientific progress.
In this article, we will show you 21 pictures depicting the greatest scientific and medical achievements of the past year.
The photos were created through different techniques, including illustrations, medical scans, and even Super
Resolution microscope.
Some are too surreal to believe they are true! 20.
This may be one of the most common images you find in this list, but there is an interesting background story behind it.
Lying on the floor, a man is undergoing an eye examination at a temporary clinic founded by the famous non-governmental organization "joint vision.
Image: provided by the National geographer, this NGO is designed to improve global eye health, and over the past few years it has provided more than 90,000 cataract surgeries and has helped the CRA.
This photo aims to raise awareness of eye health issues. 19.
Digital illustration with electric pen this picture may look like a picture, but it is actually a digital illustration created by electric pen.
The picture represents Rita Levi.
Montalcini, a woman who won the Nobel Prize in physiology for the discovery of nerve growth factors in 1986.
Picture: provided by a national geographer for those who are not familiar with the world of art, digital or computer illustrations are made using digital tools through the manipulation of artists.
In turn, a digital pen is an input device that converts handwritten drawings or information into digital data. Crazy, right? 18.
If we let our imagination take us away, the shape that appears in the picture looks like a fossil of a fragment of Mandarin.
But, believe it or not, what you see below is the developmental stage of the mouse placenta. Yikes!
Image: provided by National Geographic. This picture was obtained using a co-focal microscope, also known as a co-focal laser scanning microscope, an optical imaging technique designed to improve the optical resolution of the image.
You may also want to know how the colors and shades of these contrasts are implemented, and the answer is this.
Placenta staining shows three different proteins: Blue represents the nucleus, green shows the presence of nourish cells, and red indicates blood vessels. 17.
A scanning electron microscope uses a scanning electron microscope to obtain this purple figure, and a scanning electron microscope is a microscope that creates a sample image by scanning the surface with a focused electron beam.
But can you guess what is represented in this picture?
Image: provided by the National geographer, what you see in the picture is actually tiny RNA, a small RNA molecule found in plants, animals and certain viruses.
These molecules control the growth and function of cells, and scientists are studying whether they can be used as a possible cancer therapy. 16.
Technological advances in the world of eye lens photography allow photographers to take pictures in more detail.
This is a picture of the eye, but if you look closely, there is a thin, transparent object that covers it.
Can you guess what it is?
Image: provided by the National geographer, this object happens to be an artificial crystal, also known as Iris clip, for the treatment of diseases such as cataract and myopia.
Placing artificial crystals in the eyes requires surgery.
The patient with the eyes depicted in the photo returned complete vision after undergoing surgery.
Impressed, right? 15.
The image below the pig eye model by 3D printing is created by 3D printing, a technique that includes building a three-
Size object on computer
Auxiliary design model.
This is usually done by adding materials layer by layer.
But what should this 3D object be?
Figure: The white object provided by the National geographer is a model of the pig eye.
You can see that the indentation on the right is the pupil, which allows the light to enter the eye.
The left side represents the blood vessels in the muscles around the iris. 14.
Through computer bones
This photo, taken by artist Oliver Burston, is part of a series called Stickman-the evolution of cloning.
The images belonging to this series are based on the character Stickman, another self of the artist who happens to have a condition of Chron.
Picture: provided by national geographer, this picture is made by computer
The resulting images should represent the symptoms produced by Chron's disease, a chronic gastric ological disease that causes weight loss and bone vulnerability.
The photo is creepy but impressive at the same time. 13.
The 3D model of the human brain if you look at the picture below, it looks like an item made of wool, right?
For example, a small pashmina.
Well, if you have the same impression as me, then I dare not tell you that you will not be wrong.
This image is actually a 3D model of a person's brain.
But how did it come about?
Image: provided by National Geographic. This picture is made with a 3D modeling technique called tracing photography to scan the human brain.
Tracing is used to visually represent certain parts of the brain, such as nerve bundles.
What you see in this image is actually the dark matter neural pathway that connects the two regions of the human brain responsible for language. 12.
Parrott's Computed Tomography looks like a picture of this strange and terrible image, but it was created using very complex programs.
What you see below is a combination of 2,933 pictures, each of which is 0.
1mm thick.
But how is the final product implemented?
Photo: provided by a national geographer, this nearly 3,000 images were taken with a computer tomography, a device that uses a computer
Processing combination of X
Rays produce a fault image of certain areas of the body.
In this case, X-
The light represents the blood vessels and bones of the parrot.
However, the model was slightly manipulated by digital imaging software. 11.
I don't know about you by synthesizing gel through a co-focal microscope, but I think it will be a great painting at the Museum of Contemporary Art.
See how eye-catching those purple colors are!
If you're not a science expert, it's hard to tell what this picture represents.
Can anyone guess?
Image: provided by National Geographic, this image is also made using a co-focused microscope, and this technique has been explained in previous slides.
In this case, the image shows neural stem cells in a type called PEG (
Ethylene glycol). 10.
The computed tomography of this image of Parrot looks like a digital animation, isn't it?
In fact, this is a computed tomography of a gray parrot.
Computed tomography, also known as CT scan, uses x-
Shows the light of the body's bones and blood vessels.
Image: provided by National Geographic magazine, most of what you see in this photo is the blood vessels of parrots.
You can see a dense blood mass under its neck, which helps the parrot adjust the body temperature through a process called body temperature regulation. 9.
This image was created in digital art.
Silver Ring-
Shape is the channel that spans the human cell membrane.
The light blue spheres may look like bubble gum, but they represent goods passing through the cell.
Photo: provided by national geographer. These models were created using a 3D modeling and animation program called Strata Design 3D CX.
They are then saved as PSD files and finally colored using Photoshop.
They do a great job of adding colors! 8.
Observing the mouse retina through a co-focused microscope is one of many images in the list created with a co-focused microscope technique. This leaf-
The retina of the mouse is represented like an image.
The retina is located at the back of the eye and is responsible for converting light into nerve signals.
Picture: provided by national geographer. If you are interested in more detail, what you see is not the entire retina, but a single cell called a star cell.
Star cells
Shape cells found in the brainRetina barrier7.
Eric Clarke, Richard Arnett, and Jane Burns graphical visualization of Twitter data, the weirdest of all on this list.
This picture is a graphical visualization of the data extracted from a tweet using hashtag breast cancer.
Picture: provided by national geographer. Twitter users using this hashtag are represented by small yellow dots called nodes, and the lines connecting nodes symbolize the conversation of Twitter users.
Depending on the number of connections and online status of each user, the size of the point will vary.
How many days do you think it took them to do this? 6.
Photos of Hawaiian short tail squ fish the creatures you can see below are Hawaiian short tail squid fish.
If you ask me, it looks like a computer image or a digitally manipulated image, but surprisingly neither of them is above.
Can you guess how this photo was created?
Photo: provided by national geographer. The squid was shot with a complex and complex technique, photography.
This process uses specialized lenses and multiple stitched images to create a very detailed picture.
If you encounter a squid in real life, it is impossible for you to find its yellow and black dots, or it has different colors of orange on its head! 5.
With a co-focused microscope, the rat's spine knows what you're thinking: These three images-they look a bit like winter slippers, to be honest, don't they?
Completely surreal.
But whether you believe it or not, they're real.
Life images of spinal cord development in embryonic mice.
Who will think of it?
Photo: provided by National Geographic, but this is not an ordinary image as it is made using a sophisticated technique called a co-focal microscope.
As we can see, with this technology, light like a laser is stacked to create a 3D reconstruction of a specific microscopic image. Cool, huh? 4.
"Hidden learning" painting this looks like a digitally manipulated image, but it's actually the only regular drawing in this list.
It was made by illustrator Sophie McKay Knight called hidden learning.
This picture is part of so-.
The art movement, called the "pupal program", aims to bring together female scientists.
Picture: The painting is provided by a national geographer to represent what women feel they are hiding in their work environment, such as the constant struggle between their career and their family life.
This woman carries a veil, and only professional scientists will notice that it is composed of the molecular structure of sugar molecule 3.
Cat skin knows what you're thinking through a polarized microscope: this must be a picture!
Believe it or not, this image shows different types of tissue found in certain parts of the cat's skin.
But how is this image created?
Why all these colors?
Photo: provided by National Geographic. The cat's skin image was made with an optical microscope technique called a polarized optical microscope.
This technique involves irradiation of samples with polarized light.
In other words, this microscope separates light through different materials and directions, resulting in a wide range of colors. 2.
Zebrafish embryos observed through a co-focal microscope this crazy image full of fluorescence looks like a digitally manipulated painting, but is actually created using a co-focal microscope.
You can never guess what this picture represents because it should be a zebrafish embryo.
Image: provided by National Geographic, but how can we explain this color?
The embryo was injected with a stained red gene that researchers wanted to manipulate.
Scientists are interested to see if the injection of this gene affects the learning behavior of fish and the response of predators. 1. Super-
It's hard to believe this is just a painting, right?
Believe it or not, this picture uses a type called super-
Resolution imaging.
This method improves the resolution of the imaging system.
Resolution microscope.
