(PhysOrg.com) -- Despite ongoing efforts to save the trees, many offices print high volumes of paper documents on a daily basis. Although many companies encourage paper recycling, both disposing of and recycling paper have ...
A team of researchers from MIT and Harvard University has come up with a way to get 3-D printers to print objects using data sets rather than geometric representations. In their paper published on the open access site Science ...
Since lasers were invented more than 50 years ago, they have transformed a diverse swath of technology—from CD players to surgical instruments.
