Researchers 'un-can' the HIV virus

If the human immunodeficiency virus (HIV) is a bit like a hermetically sealed tin can no one has yet been able to break open, the good news is that researchers at the CHUM Research Centre, affiliated with the University of Montreal, have identified a way to use a "can opener" to force the virus to open up and to expose its vulnerable parts, allowing the immune system cells to then kill the infected cells.If the human immunodeficiency virus (HIV) is a bit like a hermetically sealed tin can no one has yet been able to break open, the good news is that researchers...

This image sparked scientific debate when it was released last year, with researchers arguing over whether newly forming planets were responsible for gaps in the dust and gas swirling around the young star.A recent and famous image from deep space marks the first time we've seen a forming planetary system, according to a study by U of T astrophysicists.

'Microcombing' creates stronger, more conductive carbon nanotube films

<p>When a carbon nanotube (CNT) ribbon is dragged between two surgical blades, the blades function as a "microcomb" that pulls the CNTs into alignment -- just as a regular comb sorts through tangled hair.

<p>When the ribbon of aligned CNTs is being wound onto the spool, the researchers apply an alcohol solution to pull strengthen the bonds between CNTs.

<p>The CNT ribbon wraps around itself as it winds around the spool, creating a layered film of pure CNTs.Researchers from North Carolina State University and China's Suzhou Institute of Nano-Science and Nano-Biotics have developed an inexpensive technique called "microcombing" to align carbon nanotubes (CNTs), which can be used...
