What Is It? #7

What Is It? #7

What Is It? #7 (click to enlarge)

It’s that time of the week again – time for our What Is It? competition. Same rules as always apply, check out the image and tell us what it is.

Last week we showed you this photo, and asked you what it is. The answer? It’s a photo of nanoparticles (in brown) attaching themselves to cancer cells (in violet) from the human abdominal cavity. This is actually pretty cool – scientists at Georgia Tech and the Ovarian Cancer Institute have further developed a potential new treatment against cancer that uses magnetic nanoparticles to attach to cancer cells, removing them from the body. The treatment, tested in mice in 2008, has now been tested using samples from human cancer patients. The results appear online in the journal Nanomedicine. [Image Credit: Ken Scarberry/Georgia Tech]

It was a difficult one, sure enough, and nobody got it entirely correct, but the closest to the correct answer was Stan T, with this guess:

Out of focus bone marrow aspirate, acute leukaemia, non specific esterase stain.

A partial congratulations to Stan T for coming closest – let’s see you all raise your game for this week’s photo!

    It looks like another STM image to me. Something that occurs in layers, perhaps graphite?

    Looks like I’ll be the winner by default at this rate…

    Crystal joints in metal (stm)

    or a bunch of silver ball cake decorations on a biscuit tin lid.

    Is it a stipple pad for artexing the ceiling?
