Now, self-healing materials can mimic human skin, healing again and again

...e researchers begin by building a scaffold using a robotic deposition process called direct-write assembly. The process employs a concentrated polymeric ink, dispensed as a continuous filament, to fabricate a three-dimensional structure, layer by layer. Once the scaffold has been produced, it is surrounde...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

A robotic vehicle designed for underwater exploration plunged repeatedly into the depths of Mexico’s mysterious El Zacatón sinkhole in late May, finding its previously undiscovered bottom 318 meters below the surface and generating a sonar map of its inner dim...

More recycling on the farm could reduce environmental problems

...me chemically treated fertilizer and would exploit robotic systems. The approach would entail more use of human labor, which is costly, and may reduce output per unit area farmed. Pearson summarizes studies of organic farming suggesting, however, that price premiums could overcome this disadvantage, and p...

From the deep -- Researchers find new species of sea anemone

...icles (ROVs). Deep sea ROVs are also equipped with robotic arms and suction devices that are used to collect species. "It's like a submarine that's manned from the surface," said Daly, who plans to head to Monterey Canyon later this year in hopes of finding more dead whales with A. pearseae roosting on th...

In-shell vaccine for chick disease

...elivered to chicks still in the egg (in-ovo) using robotic 'vaccinators'. IBV is the worst infectious disease in terms of economic loss to the UK poultry industry. Infection can lead to severe respiratory disease, dramatically reduce egg production and affect the quality and hatchability of eggs. The ...

MIT device draws cells close -- but not too close -- together

...ithout the use of tools such as the microscopes or robotic control arms typically required by MEMS devices. Because cells communicate via signals transmitted both through the touching of cell membranes and through soluble molecules that flow between separated cells, biologists need to vary the spacing of ...

His second project involves developing procedures for rapidly inventorying cave biodiversity. He has applied these methods to caves throughout northern Arizona and Belize....

Brain-computer link lets paralyzed patients convert thoughts into actions

...d close the fingers of a prosthetic hand and use a robotic limb to grasp and move objects. Despite a decline in neural signals after 6.5 months, Nagle remained an active participant in the trial and continued to aid the clinical team in producing valuable feedback concerning the BrainGate technology. The s...
