This collage shows Hubble Space Telescope images of 6 different galaxy clusters, with concentrations of dark matter colored in blue. The dark matter in these images was only detected through its gravitational pull on visible matter. But a new study says that dark matter might leave a detectable colored "fingerprint" on light.

Dark matter might leave a colorful 'fingerprint' on light Scientists have long agreed that dark matter – the mysterious substance that makes up 85% of all matter in the universe – doesn't interact with light. But a new study suggests dark matter might not be so dark after all. Researchers announced last week that dark matter might leave a faint splash of color on light it encounters. This "fingerprint" would be blue or red, depending on the type of dark matter the light passes through. The tint would be too subtle to pick up with today's technology. But the researchers say the next generation of telescopes could be designed to detect it, potentially transforming our understanding of this strange substance.

Very interesting info Julie, I's like to say sorry I havn't commented on your posts of late, I'm not getting any notifications in my inbox from this website nor some others on Ning either for some time now, its annoying cos I cant then keep up, when I come into the site, as I have to respond & work off the activity feed only and it only goes back so far.. so I let them go.. Ning have been told but they do nothing about it..my ticket dosnt even get responded to even its that bad, they just want money for these sites these days and try to get away from assisting on them..

Yes I have noticed that Ning haven't been performing well Vlada, and like you the activity panel has been the key to activity/posting on Ning sites.  Good to know you're still online and here.  I've tried to keep moving the front page with activity as and when I can.
