What are XenoBots?

Xenobots or you can say human made living lifeforms are the type of robot which are made of living tissues and cells to work at microscopic level for different purposes like drug delivery to specific part of the body, collecting microplastics in the oceans and seas to make a large blob, etc.

These synthetic robots are made of skin cells and heart muscle cells derived from stem cells which are took from frog embryos. Here, skin cells works as protection shield for heart cells where heart cells drive the xenobots moving mechanism. The structure of the bots are designed in computer  simulation using evolutionary algorithms that uses trial and error method. 

The manufactured organism is layered with heart muscle (now glowing red). AI optimized the shape of the organism and the location of its muscle to produce forward movement.

Xenobots are capable enough to move inside living bodies and have life of weeks. These bots are also able to heal themselves. Xenobots are able to work in swarm to execute large task to move some specific  material at microscopic levels. They have ability to self replicate new xenobots with same features. Xenobots have size of aorund 0.4 millimeters.

AI methods automatically design diverse candidate lifeforms in simulation (top row) to perform some desired function, and transferable designs are then created using a cell-based construction toolkit to realize living systems (bottom row) with the predicted behaviors.

First xenobots were made using AI program developed by Sam Kriegman. “We asked the supercomputer at UVM to figure out how to adjust the shape of the initial parents, and the AI came up with some strange designs after months of chugging away, including one that resembled Pac-Man,” says Kriegman.

In current world, xenobots are in completely experimental research frame and more use cases are being tried to find out.

Batteries that are better than Lithium-ion batteries - Science Feed

By
Hello, This is your Science Feed. As we know Lithium is used in most of our electrical equipment, mostly in our smartphones. But, these batteries have their own limitations which are annoying. The biggest reason is that Lithium-ion batteries explode vigorously. Another reason to replace Lithium-ion batteries is their short life and low charge-storing capacity. Today, We will check out those batteries which are better than our Lithium-ion batteries. Here we go; Sodium-Ion Batteries               These batteries are quite similar to Lithium-ion batteries because sodium ions are used instead of lithium ions as the charge carrier. The development of both types of batteries started side-by-side but lithium-ion batteries over took sodium one. There are lots of advantages of using sodium-ion batteries over lithium-ion batteries. First of all, Sodium is the sixth most abundant element on Earth. So, no problem with its availability. In terms...

What is Fermi Paradox? - Science Feed

By
Have you ever thought why we have not found any advanced intelligent organism yet? Or is there any other type of life form outside our planet Earth? These are the basic questions that come into mind when we talk about Fermi Paradox. Fermi Paradox Fermi paradox is the lack of compatibility or contradiction between the high chances of existence of extraterrestrial civilization in the universe and lack of evidence to find them or communicate with them. This was termed after the name of physicist Enrico Fermi. It casually came in head of Fermi during talk with his colleagues and he asked, "Where is everybody?". Early and Related Theories Before Fermi Enrico, the founding father of modern rocket science  Konstantin Eduardovich Tsiolkovsky, a  Russian scientist, proposed Zoo hypothesis. In Zoo hypothesis, it is speculated that the extraterrestrial civilization knows about our existence but instead of contacting us, they opt to do observation on us similar to animals in zoo.  Th...

Falcon 9 (SpaceX) - Science Feed

By
Hey, this is Science Feed, and this post is about Falcon 9, one of the most advanced rockets in the world. Before we get started, we request you subscribe to our blog so that you never miss our informative posts. We also recommend you follow us on these social media platforms. Facebook         Twitter          Reddit          Pinterest         Instagram Falcon 9 is the first reusable orbital-class rocket that can be used more than once. SpaceX has designed and developed it for payload transfer to Earth orbit and space. Over the time period of 10 years, Falcon 9 has been launched 85 times, in which 46 launches were able to land. Due to its capability of landing, SpaceX has saved costly parts of the rocket. This rocket uses rocket grade kerosene (RP-1, it is cheaper but less explosion hazardous fuel, which is a highly pure form of kerosene) as its fuel and liquid oxygen as an oxidizer.  In 2007,...
