The Russian developed a method of printing artificial bones

3D printers are used not only in industry but also in medicine, and their properties allow them to create models of organs for training surgeons, as well as artificial bones used for transplants. However, a Russian student developed a completely new method of their production, which gives the product most similar to the real bone tissue.

Medicine is one area in which 3D printers are gaining in importance. There are projects to use them for the production of personalized pills, which, thanks to the ability to fine-tune the dosage of drugs, will be much more effective than mass-produced medications. They are also used to create realistic models of organs that allow surgeons to dry out on a dry basis, thereby increasing patient safety.

Most often they are used for the production of artificial bones that replace the real ones lost due to an accident or cancer. The use of these devices will soon become even more widespread, as Nikita Toropka, a student at Tomsk University of Technology, has developed an innovative method of using 3D calcium phosphate printing, which makes the finished product almost identical to human bone tissue and can become a cheaper alternative to traditional prostheses. bones.

The use of FDM 3D technology has made the artificial bone fully biocompatible with the body, so there is no risk of rejection. In addition, it is biodegradable and, despite the porous surface, extremely durable.

Our 70 percent bones are composed of calcium phosphate, so that the prostheses have been approved by the body, and must also contain its components. The idea of ​​their use is not new, but the innovation of the method invented by Toropek is not so much to choose the quantity of the component as on the method of printing.

Previous methods have used SLS 3D technology and although it allows for precise printing of porous objects, their strength is not even close to the strength of human bone. However, the student has managed to develop a method that produces bone density and almost identical strength as human bone tissue.


Nintendo will return to VR technology?

Not everyone knows, but before Oculus VR was created and we heard Oculus Rifcie for the first time, the Japanese company Nintedno has been experimenting with VR technology for years, called Virtual Boy. This was an unlikely experiment, but Nintendo apparently did not completely abandon the idea.

Microsoft is working on HoloLens, which will probably work with the Xbox One, Valve has created HTC Vive with HTC, and Sony has its PlayStation VR. The Japanese giant Nintendo does not want to be inferior to its rivals and is also considering developing a VR kit for entertainment.

Although the company once tried to implement such technology, it was a device called Virtual Boy, but then technology was not developed enough to provide good image quality, so the project turned out to be a failure. Now it is completely different and the current president of Tatsumi Kimishima, during the presentation of financial results said that this is a very interesting technology and Nintendo is considering the creation of its own VR device. For now, these are only preparations and there are not yet specific plans to release such equipment to the market.

Kimishima’s statement is a complete change of Nintendo’s approach to VR technology. In recent years, both Shigeru Miyamoto and the head of the US Reggie Fils-Aime division, have been skeptical about this solution, claiming that they will not give players any fun and do not fit the philosophy of the company.


Apple will offer accessories for the disabled

The Cupertino company has for years been striving to design devices that are as easy to use as possible, which is especially useful for people with disabilities. Now the company will increase the number of such products and has just announced that it will soon be introducing entirely new accessories to its stores.

Apple is known for taking care of the needs of people with disabilities so that their equipment is designed to be as comfortable as possible for them. Tim Cook recently said that the company will continue to do so even if it does not bring its desired profits.

The next step in the implementation of this plan will be the sale of new accessories specifically designed for the disabled, which will be available in the company’s stores, as well as in its online store.

At the moment, it is not known what accessories it will be, but one may guess that hearing aids may be present. One such device is ReSound, which goes beyond the standard functionality of a typical hearing aid, connecting to mobile devices such as the iPhone.


Hulu will soon be offline

The well-known Hulu video service confirms that soon its users will have access to the new option. It will be offline, allowing you to download content to disk and watch it at your own convenience.

Filming websites have it all up to them that you need to have a permanent internet connection to use them. This is not a very convenient solution, especially since not everyone has at their home a fast connection at home, which will allow you to enjoy content comfortably.

A much better option would be the ability to download the selected movie or TV show to disk in a high-speed location, such as an internet café or at work, and then watch it at home. Netflix has been offering this opportunity since last autumn, and will soon introduce it to Hulu.

The CEO of Mike Hopkins officially confirmed this fact when talking to AdWeek. He promised that the feature should be available to users shortly, though he did not say when exactly this would happen.


Traffic light for smartphone users

The authorities of the German city of Augsburg have decided to take care of smartphone users who write text messages while traveling on sidewalks. Especially for them, a new type of traffic light was installed on the pedestrian crossings.

Surely you did not once see the person walking on the pavement, holding the smartphone in his hand, all his attention focused on the text message just written. Someone is not aware of what is going on around him, and this is very dangerous, because he can not only fall into the pole and severely beaten, but also fall into other people, and even under the oncoming cars.

Some countries, such as Belgium and China, set off special paths for smartphone users on the pavements, while in the German city of Augsburg it was decided to ensure the safety of such people while crossing the street.

Smartphone users do not always pay attention to the traffic lights, sometimes going to the red light switch, so the idea of ​​city sprinklers assumes installation on the crossings of additional signaling. As we know, smartphone owners who write messages have their heads pointing downward, so the sets of flashing red lights are built into the roadway, which should be easy for them to notice. They inform you that you can not now enter the zebra.


Cortana blocks the microphone on the android

Cortana, a digital assistant created by Microsoft for Windows Phone, has also recently become available for other platforms. Unfortunately, its performance is far from perfect, and for Android smartphones, users may expect problems with the microphone lock.

Microsoft plans to make Cortana available to as many users as possible, so the recent digital assistant is also tested on the Android platform. Keep in mind that this is a very early version, and therefore may have minor or major problems.

One of the issues that Nexus 5 users are seeing is blocking the microphone, which prevents the phone from being used. Restart device does not give anything because the problem comes back after some time.

Originally thought to be unresolved and the only solution was to uninstall Cortana, however, it was discovered how to fix the problem without getting rid of the assistant. All you have to do is to uncheck the “Hey Cortana” function to enable voice activation. I suppose that’s why it’s causing the microphone problem, because it interferes with a similar function provided by Google.
