D’un point de vue physiologique, le noyau pulpeux, la partie centrale des disques intervertébraux, est le premier touché. Il est composé en grande partie d’eau, ce qui lui confère ses propriétés d’amortisseur. Avec l’âge, les cellules pulpeuses deviennent progressivement moins prolifératives, plus sujettes à l’apoptose et incapables de produire cette fameuse matrice extracellulaire très hydratée.

Comment alors les remplacer par des cellules fonctionnelles ? Les chercheurs se sont intéressés au tissu adipeux qui constitue un grand réservoir de cellules souches capables de se différencier dans une vaste gamme de types cellulaires. Encore fallait-il trouver le bon protocole pour réussir à ce que des cellules souches du tissu adipeux puissent se transformer en cellules du noyau pulpeux.

Scientists discover that eyes really are 'the window to the soul'

Scientists discover that eyes really are 'the window to the soul' | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

The eyes really are a window to the soul, according to scientists.

Patterns in the iris can give an indication of whether we are warm and trusting or neurotic and impulsive, research has found.

Everyone has a different structure of lines, dots and colours in their iris.

So scientists at Orebro University in Sweden compared the eyes of 428 subjects with their personality traits to see if these structures in the iris reflected their characters.

They focused on patterns in crypts - threads which radiate from the pupil - and contraction furrows - lines curving around the outer edge - which are formed when the pupils dilate.

Their findings showed those with denselypacked crypts are more warmhearted, tender, trusting, and likely to sympathize with others. In comparison, those with more contraction furrows were more neurotic, impulsive and likely to give way to cravings.

The researchers argued that eye structure and personality could be linked because the genes responsible for the development of the iris also play a role in shaping part of the frontal lobe of the brain, which influences personality.

They say the findings could one day be used in psychoanalysis and by companies screening candidates for jobs.

The Nanodoctor Will See You: Tiny Particles May Help Fight Disease

The Nanodoctor Will See You: Tiny Particles May Help Fight Disease | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
Researchers are designing tiny particles to act as medicine.

 

The particles are coated with waterlike molecules that allow them to travel inside the body without being detected by the immune system, Farokhzad said. Their surfaces contain molecules that provide them with a "GPS" to seek out abnormal cancer cells.

 

Once they find a cancer cell, the particles stick, and like a Trojan horse, the cancer cells take them inside where they can release medicine that's toxic to the cell, Farokhzad said. [Watch the World Science Festival Live.]

 

In a study published last year in Science Translational Medicine, Farokhzad and colleagues showed that, in people, the nanoparticles delivered a much higher dose of medicine to cancer cells than to other cells in the body. Follow-up studies will test the effectiveness of the drug at treating tumors.

Reservoir deep under Ontario holds billion-year-old water

Reservoir deep under Ontario holds billion-year-old water | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it
Search is on for signs of microbial activity isolated in Earth's crust.

 

15 May 2013

Water filtering out of the floor of a deep Ontario mine has been trapped underground for more than a billion years. It bubbles with gasses carrying nutrients that could sustain microbial life.

 

Scientists working  2.4 kilometres below Earth's surface in a Canadian mine have tapped a source of water that has remained isolated for at least a billion years. The researchers say they do not yet know whether anything has been living in it all this time, but the water contains high levels of methane and hydrogen — the right stuff to support life.

 

Micrometre-scale pockets in minerals billions of years old can hold water that was trapped during the minerals’ formation. But no source of free-flowing water passing through interconnected cracks or pores in Earth’s crust has previously been shown to have stayed isolated for more than tens of millions of years.

 

“We were expecting these fluids to be possibly tens, perhaps even hundreds of millions of years of age,” says Chris Ballentine, a geochemist at the University of Manchester, UK. He and his team carefully captured water flowing through fractures in the 2.7-billion-year-old sulphide deposits in a copper and zinc mine near Timmins, Ontario, ensuring that the water did not come into contact with mine air.

WOW, to be followed for further...
