J-Innovators:
A Scanner that Produces Ultra-high-resolution Images
What's like a photograph, but isn't a photograph? The answer: scanned images! A new kind of scanner can create realistic images of just about anything. In fact, the images are so realistic they almost appear to have texture. This scanner can capture the tiny details of tatami mats as well as the polished wooden corridors and garden at a famous Kyoto temple. The images are so detailed that when they are printed out, they appear 3D! Reporter Michelle even got herself scanned. Tune in to see if you can tell the difference between the real Michelle and her scan!

Science News Watch:
Magnesium Ions and Long-term Memory
Science watcher Katsuyuki Sakai reports on research that is revealing the role of magnesium ions in long-term memory. A team including researchers from Tokyo Metropolitan Institute of Medical Science manipulated fruit fly genes to halt magnesium ion activity in the brain. When they did this, they found that the flies didn't retain new memories for more than a day. Scientists have known that there is a connection between calcium and memory, but this is the first time scientists have found evidence that magnesium also plays a role.

The Leading Edge:
Shape Shifting Neurons
There are roughly 100 billion neurons in the brain. Neurons can live up to 120 years, but unlike other cells, they cannot divide. How do neurons store our memories? On this episode of Science View, we focus on new research that aims to answer that question. An advance in imaging technology has made it possible to observe neural activity in real time using a method called two-photon microscopy. Using this technology, scientists have revealed the dynamic life of cells.

I can't re-post files, sorry. The exception is files that are less than a day old. All mediafire links are broken forever. If you ask nicely and show that you tried but couldn't find the file elsewhere, someone may share it again.
