The toxic killers in our air too small to see - BBC Future

The biggest killer of all never makes the headlines, isn’t regulated, and is barely talked about beyond niche scientific circles (despite their best efforts to change that narrative): it’s nanoparticles.

PM2.5 may be too small to see, being roughly 30 times smaller than the width of a human hair. But, compared to a nanoparticle it’s a relative heavyweight. PM2.5 stomps in at 2,500 nanometres (nm), while the real killers are 100nm or below. This issue is that local authorities consider PM2.5 and any particle smaller than it to be the same – which means that often their reports underrepresent the true risks.

The science of why we should be concerned about the total number of particles that we breathe in, not just their mass, has been known for some time. In 2003, Surbjit Kaur was a young researcher finishing her Masters at Imperial College London, when her supervisor suggested she join the Dapple experiment (the Dispersion of Air Pollution and its Penetration into the

NASA finds Neptune moons locked in 'dance of avoidance'

Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.

Orbital dynamics experts are calling it a "dance of avoidance" performed by the tiny moons Naiad and Thalassa. The two are true partners, orbiting only about 1,150 miles (1,850 kilometers) apart. But they never get that close to each other; Naiad's orbit is tilted and perfectly timed. Every time it passes the slower-moving Thalassa, the two are about 2,200 miles (3,540 kilometers) apart.

Two Trails, One Day
 
Ce matin un épais brouillard m'entourait lorsque je remontais, non sans difficulté, jusqu'aux falaises qui se referment sur le ravin de Vallaguière. Ce matin j'avais vraiment la sensation d'être à mille lieues de chez moi.

Il y a de nombreux trésors autour de Quissac (Gard), et notamment cette superbe reculée karstique dans le massif du Coutach, l'héritage de millions d'années d'érosion. Cette vidéo est brute (sans montage), aussi vous constaterez qu'elle est loin d'être parfaite. Voici donc un aperçu du bonheur que nous éprouverions en survolant ce très beau ravin de Vallaguière.

Je n'ai pas encore bien compris (découvert) Diaspora, la seul chose dont je suis sur, c'est qu'il faut quitter les facebook, google et compagnie, au plaisir de découvrir des choses simples qui me plaissent. A bientôt peut être, toutes et tous ;)

That is where Greenpeace funding primarily is directed - towards raising more funds in order to pay the wages and the operating expenses of what has become one of the largest feel good organizations in the world. Let's face it Greenpeace has become the generic environmental organization and people feel when they join Greenpeace that they are part of the solution and not part of the problem.

Une autre photo dans ma série des Gorges du Crespenou. A quelques dizaines de mètres au dessus de la rivière qui a sculpté le calcaire au fil du temps. Nous sommes dans une échelle de temps difficilement imaginable... une échelle bien loin du temps « humain ».
