The world's smallest Olympic logo is not so much than one hundredth of an inch tall. The cell-sized logo, which measures about 50 by 100 micrometers, is tranquil of ink printed one-molecule thick onto gold. Northwestern chemists created the PR-savvy image to show off a starting anew lithography technique that they published ...

Rat neurons can be used to control simple robots, researchers communicate. By hooking up hundreds of thousands of fetal desert one's party brain cells to a wheeled machine via an array of electrodes, the neurons' spontaneous firing can direct its motion, University of Reading scientists announced yesterday. The work is a fascinating bioengineering feat, but the robots ...

In a mat of lowly bacteria fix in a foul-smelling hot spring near Mono Lake, California is a living window into Earth's early history, a unoccupied time when photosynthesis was barely evolved and the atmosphere non-existent. The bacteria, discovered by a team of American scientists, doesn't need oxygen to photosynthesize. Instead it uses arsenic, a toxic ...

Dengue fever, a viral disease that affects over 100 million people through year, has neither a vaccine nor a cure. To remedy that problem, researchers have picked through the pathogen's genome and found a wealth of weak spots. In a paper that appeared on the PLoS Neglected Tropical Diseases website yesterday, Asif Khan and Olivo Miotto ...

Every so often, Mother Nature passes along a gentle reminder of her genius. To wit: of the 128 billion synapses used to connect the 16 million neurons of an average mouse brain, about 100 are needed to convey to the animal a sense of its own succeed. For a mouse, self-knowledge of rapidity is profoundly important. ...
