Scientists create new life form with 'living' robot that cleans toxic spills

A team of scientists from the University of Vermont working with researchers from other institutions, has been able to repurpose living cells. The immediate application the researchers are suggesting is healthcare, where the Xenobots can be sent to pick a payload like medicine and carry it to the specific place inside the patient. At the same time, however, these xenobots are remarkably lifelike in that they're comprised entirely of biological materials, feed off energy supplied by their cells, move with intent and even fix their injuries.

The latest in technological advancements is the first ever, living, self-healing robot, created using stem cells from frogs. He also said the new robots are "artfact", "a living, programmable organism". These might include targeting toxic spills or radioactive contamination, collecting marine microplastics or even excavating plaque from human arteries, Levin said in a statement. This would make them useful for functions like delivering drugs inside the human body. It is the first time that humanity has been able to create "completely biological machines from the ground up", the team behind the discovery write in a new paper.

The scientists would assign a desired outcome - such as locomotion - and the algorithm would create candidate designs aimed to produce that outcome.

After 100 unbiased runs probably the most promising have been chosen for testing - primarily based on what pores and skin and cardiac cells can do. Researchers were able to scrape living stem cells from frog embryos and leave them to incubate.

These reconfigurable organisms have been proven to have the opportunity transfer in a coherent style - and discover their watery surroundings for days or perhaps weeks. Instead, they look more like a tiny blob of moving pink flesh. The prospect of so-called living robots - and using technology to create living organisms - understandably raises concerns for some, said Levin.

The robots have been formed out of living cells, and are in themselves entirely new life-forms. "For these people, hard questions could arise about whether these xenobots should be classified as living creatures or machines", says Thomas Douglas, a senior research fellow at the Oxford Uehiro Centre for Practical Ethics. Unlike traditional materials, the robots can be sliced nearly in half and will fix themselves back together again, they claim.

What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms?

Every design is then trialed in a virtual environment to see how well they move and whether the heart cells are beating.

In regards to how the frog cells' genomes are edited to make the new living machines, it seems that's unclear.

"The big question in biology is to understand the algorithms that determine form and function", says Levin. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences". "A first step towards doing that is to explore: how do living systems decide what an overall behaviour should be and how do we manipulate the pieces to get the behaviours we want?"

Mobile wallet Ipaymu and QR codes increase sales in Indonesia

Nowadays the majority of payment transactions in Indonesia are conducted by means of cash. However, modern technical solutions soon will be able to change this situation. Recently an e-wallet Ipaymu was introduced to citizens of the country, which will help to draw attention of smartphone users with the possibility to make mobile payments by means of QR technologies and will probably increase the popularity of cashless payments.

QR codes are used for medical purposes

QR codes have gained popularity around the world. They are used in all spheres of a human activity, helping him to get quick access to the information of his interest, for convenience of making purchases and payment of bank receipts.

New opportunities with the mobile wallet of FIS based on QR codes
