The Bitcoin network has been heavily congested for a long time, with transaction fees reaching $ 50 in December 2017. After the CryptoKitties game appeared on the Ethereum platform, it became apparent that it had similar problems.
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.
Ethereum Biggest Opportunity (Why These Altcoins Will Explode)
Ethereum has become the most popular coin among scammers according to Kaspersky Lab reports.
In addition to exposing the dizzying earnings of scammers in the second quarter of this year, a recently published report from Kaspersky Labs showed that Ethereum has become a favorite coin for cryptocurrency scammers.
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
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.
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.
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.
Chinese smartphone manufacturer Xiaomi registers new brand POCOPHONE in the USA.
Due to the increasing cases of mistrust in the Chinese manufacturer, Xiaomi decided to rebrand and register a new trademark in the US, EU and other regions. By the end of this year, it is planned to start producing POCOPHONE smartphones. However, apart from the name, in fact, nothing will change, since the production facilities will continue to be located in China..
Gadgets with the Xiaomi logo may disappear completely or they will be made only for the domestic market. The appearance of the new brand is still unknown, but the first samples have already begun to be released. It is expected that in the coming year the company will completely switch to the production of American smartphones made in China..
Recall that ended a seven-year legal battle between Samsung and Apple.
According to the analytical site transactionfee.info, the daily number of Bitcoin transactions (BTC) has reached the level of January 2018, which indicates the development of the cryptocurrency ecosystem..
