Tubeless tires have become pretty much standard mountain bike a higher level, thanks in part to the fact that they are able to neutralize their own small punctures. When it comes to big damage the integrity of the camera, but they still need a little help. That is why the award-winning South African cyclist several Stefan Deputy created a device that Sahmurai Sword.

System with two parts using the same type of sticky “worms” used in troubleshooting punctures in tubeless road tires. Some cyclists have already committed themselves to the use of a technology such kits, but often use the road counterparts in cycling is not comme il-faut, to take at least the same pump. Yes and technological characteristics of such accessories are slightly different from the needs of a cycling industry. Above these circumstances and puzzled cyclist-athlete from South Africa.

His Sahmurai Sword fastened bicycle front wheel on the tube. When the tire has to be fixed, plug spinning / stretching to show the tools that are included. Cyclist first uses a similar sila scan to make a puncture large enough for implementation of the “worm”. Then something like a fork is used to correct its position within the chamber.

Sahmurai Sword is now available in South Africa. There he stands 350 ZAR (approximately 29 US dollars). Delivery to other parts of the world still in the plans, but they promise to make a reality already in this half.

Humanity is not intended for life in space. Not at the global level, and so we in space. meaning outside of our atmosphere

the planet. This is one of the fundamental truths that were forced to admit during the short period in which humanity is often visited by low Earth orbit. To better understand the adverse effects of microgravity on the human body, the Japanese Space Agency (abbr. – JAXA) conducted several experiments centering around the observation of changes in the body of a tiny roundworm called Caenorhabditis Elegans.

Currently, astronauts have to participate in the very time-consuming training, using specialized equipment on a daily basis throughout the long period of stay on the ISS in an attempt to mitigate the adverse effects of microgravity. However, regardless of the precautionary approach, the average astronaut will return to earth, losing an average of about 2% of bone mass for each month stay aboard the station.

The study took place on a global scale. It involved equipment and training institutions such as Antarctic base Concordia, owned by ESA, as well as educational institutions, such as King’s College London, which engaged in the development of space suits, which can simulate the effect of gravity.

Caenorhabditis elegans was chosen as for instance the study because of its physiology can be used as a model of small bones and muscles of larger animals, such as humans. Less than 1 mm in length, at the roundworm has many advantages over other living specimens of animals – for example, a short life expectancy (approximately 2-3 weeks in a lab environment) that allows astronauts to grow several generations, while they are on board the station.

In JAXA hopes to benefit from this feature, watching as genetic adaptation to microgravity environment of the ISS progresses at the cellular level from generation to generation. “Astronauts grow a few dozen generations of the body, and then we can investigate organisms in various states of development,” said Atsushi Higesiteni, Research Project Manager from Tohoku University.
