A Cornell-developed camera that fits on the head of a pin, contains no lenses or moving parts and costs pennies to make could revolutionize an array of scientific fields from surgery to robotics. Writing about the device in the journal Optics Letters, the researchers say it is only 100th of a millimeter thick and one-half […]
Gene therapy theoretically makes it possible to introduce genes into cells to cure disease or address deficiencies in biological processes. But in order for gene therapy to work, foreign (or synthetic) DNA must be introduced into host cells, which is a non-trivial task. Traditionally, researchers inserted foreign DNA through the cell membrane which had been […]
A tiny contraption made by trapping organic molecules between metal nanoparticles has successfully generated electricity from heat; an achievement that the researchers believe could lead to more efficient ways to directly convert heat into electricity. Around 90 percent of the world’s electricity is created through the indirect conversion of heat, but inefficient conversion means that […]
