Connective tissue

Anne Weston, London Research Institute, Cancer Research UK

This false-coloured scanning electron micrograph shows connective tissue removed from a human knee during arthroscopic surgery. Individual fibres of collagen can be distinguished and have been highlighted by the creator using a variety of colours. The horizontal field width of the image is 16 microns.

Steering Stem Cells with Magnets

Magnets could be a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease.

By feeding stem cells tiny particles made of iron oxide, scientists at Emory and Georgia Tech can use magnets to attract the cells to a particular location in the body after intravenous injection.

The results are published online in the journal Small and will appear in an upcoming issue.

The central nervous system (CNS) in most vertebrates forms initially as a flat sheet of cells, which subsequently rolls up and fuses shut to form the hollow neural tube, which is the precursor to the CNS. The enriched apical actin in the closing neural tube (shown in green in the image) is central to cell shape changes that contribute to the rolling up process.

Could We Stop An Asteroid From Hitting Earth?

Bill Nye the Science Guy and AsapSCIENCE team up to answer this burning question. Do we stand a chance against a giant rock, on a collision course for Earth?

Well, that’s a pretty special guest there, guys! 

New goal: Do IOTBS video with Bill Nye.
