Artificial Mini Heart Produced Using Human Cells

US researchers stormed an organ using cells and biological material from a human donor. A three-dimensional biological pressure produced a smaller heart than usual.

Last April, researchers from Tel Aviv University in Israel managed to produce a small heart with 3D printing. A similar study has now been repeated in the United States. Chicago-based biotechnology company BIOLIFE4D and the company’s chief scientist Dr. It was Ravi Birla.

In the initial phase of the project, white blood cells were collected from a participant and pluripotent, i.e., the ability to transform into other cells was placed in the stem cells. Then the small heart with bio 3D printing was built step by step. The shape of the heart was formed by MRI scanning of the donor’s heart.

The produced heart was placed in a bioreactor. These bioreactors can mimic the behavior of a real human body. Thus, muscles called cardiomyocytes, located in the heart rate and providing blood circulation, regulated themselves, and came together to form heart tissue.

BIOLIFE4D said that this heart has four chambers like a real heart and has the same characteristics as a genuine heart. The firm did not make a statement about whether the heartbeats.

It is expected that this technology will be further developed and thus, the organ will be replaced by a new one in patients with organ failure. Thus, the risk of the body rejecting the organ is eliminated.

NASA's Perseverance Rover is now actively looking for signs of life on Mars

After successfully landing on Mars some time ago, now NASA’s Perseverance rover is ready to look for signs of ancient microbial life on the red planet.

Previously this rover had explored a number of areas on Mars and collected rocks from the planet. But now the rover will be even more active to search for information on the planet.

Currently, the rover has 43 sample tubes which will later be filled with rock fragments and Martian dust to be sent back to Earth for further investigation. The process was carried out at four locations including Jezero.

Well, after that, Perseverance will then make a long journey to the north, an ancient river that is said to have been one of the sources of life on the planet Mars.

Scientists hope that at this location, the Perseverance rover can find minerals that can later be used to preserve fossils of ancient life after biological processes.

NASA and JPL are now also quite often providing updates regarding their rover while on Mars. Some time ago his party also uploaded a view of the surface of the planet Mars in 360-degree mode on its official YouTube account.

Scientists Say Humans Can Actually Live Longest Up To 150 Years

Scientists Say Humans Can Actually Live Longest Up To 150 Years

How long can humans actually live? Of course that is one of the interesting questions that we cannot answer for sure until now.

The reason is why don’t we research about how long humans can live like some species of turtles that can live up to 100 years or dogs that can live between 10-13 years.

For now, the oldest human in history is a woman named Jeanne Calment who has lived to 122 years and 164 days.

Quoted from Ubergizmo, recently a number of researchers named Timothy V. Pyrkov, Konstantin Avchaciov, Andrei E. Tarkhov, Leonid I. Menshikov, Andrei V. Gudkov, and Peter O have conducted a study to find out what the maximum age of humans is.

And it turns out from the study, it is stated that humans have the longest lifespan of up to 150 years. The reason is more than that, the human body will not be able to survive disease and injury at all so it is very difficult to survive.

However, to make humans able to survive up to 150 years, of course, is very difficult because now there are many factors that can ‘shorten’ human life starting from the environment, food, and others.

The researchers still believe that by doing therapy, they can extend human life or at least make the body still able to ward off disease and stay healthy for more than 150 years. What do you guys think?

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

An aviation startup is working to make hypersonic aviation a reality by allowing people to travel around the world from one place to another in just one hour.

Quoted by Bloomberg, Monday (31/05/2021), Venus Aerospace Corp. said that the spacecraft hipersoniknya will be able to carry passengers from Los Angeles to Tokyo in about an hour – low who otherwise take 11 to 13 hours.

The company is the brainchild of former Virgin Orbit LLC employee Sarah Duggleby (code-writing launch engineer) and her husband Andrew Duggleby (launch, payload and propulsion operations).

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

The idea came after the couple missed Sarah’s grandmother’s 95th birthday due to the long duration. Although we have never heard of supersonic jets – jets that travel faster than the speed of sound. Now, Venus Aerospace is developing a hypersonic jet, which is much faster than a supersonic.

This hypersonic aircraft can fly more than 14,000 km hour, to the end of the earth in just 1 hour

Venus has planned a space path as fast as 9,000 miles per hour or about 14,484 kilometers per hour. This is almost 12 times faster than the speed of sound (a maximum of 1234 km/hr).

Venus currently has 15 employees and most of them are veterans of the space industry. They have received investments from venture capital firms such as Prime Movers and Draper Associates.
