IOTA will move to a decentralized transaction confirmation mechanism

The IOTA Foundation announced the completion of the development of a fully decentralized mechanism for verifying transactions and protecting the blockchain.

The Coordicide protocol update removes the centralized «coordinator» when validating blocks, and also solves the problem of network scalability. New mechanism, like the previous one, will also be responsible for the security and completeness of transactions, avoiding double spending.

Jetpack Aviation develops Speeder jet flying motorcycle

Introducing our flying Motorcycle: THE SPEEDER

Jetpack Aviation is developing a prototype jet-powered Speeder flying motorcycle that can reach speeds of over 240 km / h.

The futuristic vehicle will not be similar to most existing helicopter concepts. The startup says the Speeder will be able to climb to an altitude of 4.5 km, but the flight time will be significantly limited, and for the standard model is about 30 minutes..

Initially, it is planned to place several jet engines in the central part of the structure, but this may complicate vehicle control and require the introduction of complex autonomous technologies. stabilization. Therefore, in the future, the design can be revised and the turbines can be moved closer to the edges of the hull..

Constructors it is said that it will take tens of millions of dollars to develop a design and take at least two years. So far, the startup has created a 1: 3 scale prototype that is testing flight stabilization systems..

Jetpack Aviation has already started taking pre-orders for the Speeder. Those wishing to become one of the first owners need to pay $ 10 thousand just to get into the queue. At the same time, the total cost of a patching motorcycle from the future will be $ 380 thousand..

 

The company plans to offer a variety of Speeder models, including a military version, emergency response projects and an ultralight version that can be controlled without pilot’s license. Engineers claim that although the finished product may differ from the existing concept, it will have a very similar design, size and shape..

Flight training will take about a week, as with the jetpack. However, mastering urban management skills will take longer..

Well-known car manufacturers also began to explore the potential of flying vehicles. Audi, Airbus and Italdesign are working together on the concept of an unmanned electric vehicle that can move not only on the ground, but also in the air

Laboratory-grown muscles were first transplanted into humans

Lab-grown heart muscles transplanted into a human for first time

Surgeons report successful completion of the world’s first transplant of grown muscle fibers into a damaged area of ​​the heart of a patient suffering from severe heart failure.

Instead of transplanting an entire organ, researchers at Osaka University used induced pluripotent stem cells from a patient’s blood sample from healthy donors. Modern medicine can return them to an embryonic state and turn them into the desired type of tissue, in this case, the fibers of the heart muscle were created.

Laboratory-grown muscles were first transplanted into humans

The cells grown in this way were placed on biodegradable sheets 4-5 cm wide and 0.1 mm thick, which were transplanted onto the damaged areas of the heart of a patient with ischemic cardiomyopathy. In this disease, the organ does not function well, since its muscles receive little blood; in severe cases, a transplant is required.

After operation the transplanted leaves will dissolve, and the cells will continue to grow and secrete a protein that promotes the regeneration of blood vessels, which will improve the performance of the heart.

Laboratory-grown muscles were first transplanted into humans

A team of Japanese researchers hopes this technology will help save the lives of many people, but will continue monitor the first patient for a year to assess the effectiveness of the operation and the risk of cancer, since some of the 100 million transplanted cells could potentially be malignant.

If everything goes well, then in the next three years, surgeons plan to carry out nine more similar operations on patients with the same condition..

In addition to growing new fabrics, scientists not less are successfully exploring ways to fight cancer. Recently, Korean researchers discovered protein that is able to return mutated cells back to normal.
