invention: 3d tissue printer

Justin Mullins3D printers have been around for years.
The way they work is to print a structure on one layer and one on the other to form a complex 3D shape.
Now, James Yoo of the Institute of Regenerative Medicine at Wake Forest University, North Carolina, says he can do the same with living cells.
Yoo uses a standard inkjet printer to make a layer of living cells that can then be built into a 3D structure.
Just like traditional Image printers use several different colors of ink, these structures may include several different types of cells, he said.
The system can also print dyes, make the structure easy to see, and increase the factors that promote healthy development.
Yoo says his printer can make almost anything from skin, bones to pancreas or nerve tissue-an exciting idea with great potential.

Light-
Sensitive chips located at the back of the eye have great potential to help people with certain types of vision loss.
They work by converting light into electrical signals and then directly entering the brain through nerve cells at the back of the eye.
The lens of the eye usually projects the image onto a surface called the retina at the back of the eye.
This brings problems to the light.
Sensitive chips because they have to be flat.
One way to solve this problem is to use the camera outside the eye to record the images and send them to the chip behind the eye via a wire.
But Armand Tanguay and Patrick Nasiatka of the University of Southern California, Los Angeles, said a better idea would be to implant the camera directly into the eye, but avoid the retina.
They and colleagues came up with a design small enough to implant the lens of the eye and consider the effect of the cornea on entering the light.
The device transmits the image to the chip at the back of the eye, which transmits the image signal to the nerve cells.

About 25% of the world\'s population is affected by water shortages.
Desalination plants can help, but they are often very expensive to build and operate.
Even so, there is often a need to ship a relatively small amount of water to remote areas, which can cause significant logistical problems.
Therefore, the method of downplaying relatively small amounts of water at a reasonable cost will benefit millions of people in arid areas.
A technology that shows small-
Scale dilution is called wet-
To wet (HDH)
Among them, a hot air is humidified to the saturation point by bubbling through salt water.
This airflow is then cooled, causing the purified water to condense out.
Beherda motaidri of the University of Newcastle, Australia, said one of the biggest problems with the technology is that saturated air can hold relatively little water.
This means that a lot of air has to be heated and recycled, making the process expensive.
Instead, he and his colleagues suggested using hydrogen or helium to deliver the evaporated water.
\"Gases like hydrogen and helium can hold more water vapor while showing better heat transfer and mass transfer rates than air,\" Moghtaderi said . \".
This will make HDH more cost-effective
