A computer built to mimic the brain’s neural networks produces similar results to that of the best brain-simulation supercomputer software currently used for neural-signaling research, finds a new study published in the open-access journal Frontiers in Neuroscience. Tested for accuracy, speed and energy efficiency, this custom-built computer named SpiNNaker, has the potential to overcome the speed and power consumption problems of conventional supercomputers. The aim is to advance our knowledge of neural processing in the brain, to include learning and disorders such as epilepsy and Alzheimer’s disease.

“SpiNNaker can support detailed biological models of the cortex – the outer layer of the brain that receives and processes information from the senses – delivering results very similar to ...

The research team created CRISPR guides that would cause green fluorescent protein to be expressed in only certain cellular locations and structures.

With faster, cheaper, more precise technique, authors say it’s ‘off to the races’ toward new cell therapies. In an achievement that has significant implications for research, medicine, and industry, UC San Francisco scientists have genetically reprogrammed the human T cells without using viruses to insert DNA...

Researchers succeed in shaping terahertz beams with extremely high precision. Terahertz radiation can be used for a wide variety of applications and is used today for airport security checks just as much as it is for material analysis in the lab. The wavelength of this radiation is in the millimetre range, meaning that it is significantly larger than the wavelength of visible light. It also requires specialised techniques to manipulate the beams and get them into the right shape...

New observations with ESO’s Very Large Telescope show the star cluster RCW 38 in all its glory. This image was taken during testing of the HAWK-I camera with the GRAAL adaptive optics system. It shows the cluster and its surrounding clouds of brightly glowing gas in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars.
