NEURISTOR’: MEMRISTORS USED TO CREATE NEURON-LIKE BEHAVIOR

A cartoon showing spikes of activity traveling among neurons (credit: UC Berkeley) HP Labs researchers may have figured out a way to create a chip that generates neuron-like spikes (sharp signal pulses), using a combination of memristors and capacitors to create a spiking output pattern, Ars Technica reports. Neurons encode information in the pattern and timing of  spikes. The […]

ADVANCED HUMANOID ROBOY TO BE ‘BORN’ IN NINE MONTHS

Roboy (credit: Artificial Intelligence Laboratory, University of Zurich) Meet Roboy, “one of the most advanced humanoid robots,” say researchers at the Artificial Intelligence Laboratory of the University of Zurich. Their 15 project partners and over 40 engineers and scientists are constructing Roboy as a tendon-driven robot modeled on human beings (robots usually have their motors in their […]

A NEW ‘NETWORK-EXTRACTED ONTOLOGY’ MODEL OF THE CELL

Turning vast amounts of genomic data into meaningful information about the cell is the great challenge of bioinformatics, with major implications for human biology and medicine Part of the network-extracted ontology (NeXO) hierarchical ontology of genes, cellular components, and processes derived from large genomic datasets. The ontology is shown as a tree, with nodes indicating terms […]
