Nanolaser Device Detects Cancer in Single Cells

I'm not sure if this will make that much of a difference. I wonder how many single cancer cells actually go on to develop into a tumor. I'm not sure if detecting every single cell that is cancerous is wirth it at this point, perhaps when we have cheap nanobots in the blood that can easily make use of this to eliminate the offending cell this will help.

Using an ultrafast, nanoscale semiconductor laser, investigators at Sandia National Laboratories in New Mexico, have discovered a way of rapidly distinguishing between malignant and normal cells. Moreover, this new technique has the potential of detecting cancer at a very early stage, a development that could change profoundly the way cancer is diagnosed and treated.

Mystery of metallic glass is cracked by Johns Hopkins engineers

Johns Hopkins researchers have discovered how atoms pack themselves in unusual materials known as metallic glasses. Their findings should help scientists better understand the atomic scale structure of this material, which is used to make sports equipment, cell phone cases, armor-piercing projectiles and other products.

Sonofusion Experiment Produces Results Without External Neutron Source

Hopefully this will lead to "cold" fusion that will actually generate electricty. At the moment it still uses a lot more than it generates

A team of researchers from Rensselaer Polytechnic Institute, Purdue University, and the Russian Academy of Sciences has used sound waves to induce nuclear fusion without the need for an external neutron source, according to a paper in the Jan. 27 issue of Physical Review Letters.
