University of Manchester makes made-to-measure skin and bones a reality using inkjet printers

...s thick (1,000layers equals 1cm in thickness).This method allows larger tissues to be grown than previously possible.The reason for this is the way in which the cells are inserted into thestructures.Before being fed into the printer, the cells are suspended in anutrient rich liquid not dissimilar to ink, wh...

Novel technology detects human DNA mutations

...wo-step process calledClearReadTM technology. This method sandwiches a target DNA SNP segment between two oligonucleotide sequences to greatly increase detection specificity and sensitivity. One segment identifies any mutations in the DNA and the probe, a highly sensitive gold nanoparticle, creates a strong...

There are many accounts of termites not consuming a piece of palatable wood." ### Listen to termites walking and chewing pine http://www.csiro.au/audio/termite_Feb05.mp3 Termite pictures: http://www.scienceimage.csiro.au/index.cfm?e...

“Nano-scissors?laser shows precise surgical capability

... fromthe University of Texas at Austin developed a method of laser-assistedsurgery to work on these little beasts, being able to section a singleaxon (the "arms" of a neuron) with great precision : Anultra-short pulse laser that can perform extremely precise surgery ontiny roundworms may be the key to unde...

Genome-wide mouse study yields link to human leukemia

Gene variations explain drug dose required to control seizures

...igorous clinical study is required before any such method could be put into practice, the researchers emphasized. In the March 28, 2005, early edition of Proceedings of the National Academy of Sciences, the investigators report the first clear evidence linking variation in genes involved in the action or m...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice
