A study by Australian scientists has resulted in the development of a test for blood type that can be performed using antibody impregnated paper manufacturable for a few cents per test, which is significantly cheaper than existing tests of a similar nature. This could make all the difference in the developing world, considering it's essential to test for blood type before performing a blood transfusion on a patient whose blood type is unknown. The test essentially allows blood type to be determined based on the distance the blood travels along the channels in the paper from the point where it is dropped.
Are you one of those people who like to have the TV on just for a bit of background noise? Or perhaps you'll leave it on while you're surfing the net or reading a book, in the hope that whatever comes on next will be a bit more interesting. If this sounds like you, then you might stand to save a few dollars on your power bills should you decide to get one of the new Sony Bravia TVs with Face Detection and Presence Sensor technology. These new features, which will dim or turn off the screen if you look away or leave the room, are included in the new Sony LX900 3D TV
s due out any day now. Whilst Hitachi also appears to be researching facial recognition technologies for televisions, it looks like Sony is going to be the first to release a product with these capabilities.
