Super high-res 3D laser printer: high-speed 3D printing of tiny objects
Posted by admin in Hi-tech, Science on 13. Mar, 2012 | 0 Comments
Are 3D printers not amazing enough already? Apparently some scientists at the Vienna University of Technology (TU Vienna) didn’t think so, as they have now built one that can create intricate objects as small as a grain of sand. While the ability to 3D-print such tiny items is actually not unique to the TU Vienna [...]
Supermarket checkout scanner uses object recognition instead of barcodes

Want to be the kind of person who causes entire rooms to fall silent when you enter? Researchers from the National Institute of Advanced Industrial Science and Technology in Tskuba and Ochanomizu University in Japan have created a speech jamming gun that takes the words right out of speakers’ mouths using a clever trick of [...]
Scientists use stem cells to generate human eggs in the lab
Posted by admin in Medicine, Science on 28. Feb, 2012 | 0 Comments
The conventional line of thinking says that women can produce only a finite number of egg cells over their lifetimes. Some researchers dispute this, but a new study suggests that it might not matter. Researchers at Massachusetts General Hospital claim they have isolated stem cells from human ovaries and used them to generate egg cells [...]
Wirelessly powered medical implant propels itself through the bloodstream
Posted by admin in Medicine, Science on 24. Feb, 2012 | 0 Comments
With the wait still on for a miniaturization ray to allow some Fantastic Voyage-style medical procedures by doctors in submarines, tiny electronic implants capable of traveling in the bloodstream show much more promise. While the miniaturization of electronic and mechanical components now makes such devices feasible, the lack of a comparable reduction in battery size [...]
