Carbon nanotubes found in the lungs of Parisians

This is the first recorded case of the discovery of such structures in the human body. A promising material for the future, carbon nanotubes are not yet so easy to find in life – they remain the lot of high-tech laboratories that study their properties, develop production technologies and applications.

Their potential danger is also being investigated: it has been shown that in experimental mice they cause the same violent and dangerous reaction of the immune system as asbestos, known for its carcinogenic properties. But the mice received nanotubes artificially by injecting a solution. All the more surprising is the find of French scientists who found them in the mucous membranes of the respiratory tract of ordinary inhabitants of Paris.

The authors obtained samples from mucous membranes of 64 children living in the French capital and suffering from asthma. Nanotubes were found in every single one, and in five they were found even in macrophages, immune cells working in the mucous membrane lining the lungs. Unfortunately, scientists have not yet been able to name the exact content of carbon nanotubes or their source.

Nor were they concerned with the possible connection between nanotubes and disease. On the one hand, in theory, they are actually capable of stimulating various inflammatory processes. On the other hand, their presence may, on the contrary, be the result of illness and a weakening of the body s ability to remove pollution. As for their origin, it may be quite natural: according to some data, nanotubes in some quantities may be present in the products of fuel combustion.

China has funded a kilometer-long spacecraft project

The Ministry of Science and Technology of the PRC (MOST) has allocated funds for the development of promising projects in the field of space exploration. One of them is the creation of a gigantic ship with a length of about several kilometers. And while such initiatives seem like outright gambles, they can make sense.

Climate or enemies: what locked Homo sapiens in Africa for a quarter of a million years

New scientific work shows that during the dry ice ages, African deserts expanded in such a way that our ancestors could not leave Africa. However, during the warm interglacials, the desert belt was much narrower. Why couldn t a modern man take advantage of this and populate the rest of the world earlier than 65 thousand years ago? Let s try to figure it out.
