Nearly every job is becoming more digital — Brookings study

"Not everybody needs to go to a coding boot camp but they probably do need to know Excel"
November 15, 2017

The shares of U.S. jobs that require substantial digital knowledge rose rapidly between 2002 and 2016 --- mostly due to large changes in the digital content of existing occupations. (source: Brookings analysis of O*Net, OES, and Moody's data)

Mapping connections of single neurons using a holographic light beam

New technique triggers individual neurons for mapping precise connections in real time
November 13, 2017

The researchers used an opsin protein called CoChR, which generates a very strong electric current in response to light, and fused it to a small protein that directs the opsin into the cell bodies of neurons and away from axons and dendrites, which extend from the neuron body, forming “somatic channelrhodopsin” (soCoChR). This new opsin enabled photostimulation of individual cells in mouse cortical brain slices with single-cell resolution and with less than 1 millisecond temporal (time) precision --- achieving connectivity mapping on intact cortical circuits without crosstalk with neurons. Regions of stimulation are highlighted by magenta circles. Scale bar: 20 micrometers. (credit: Or A. Shemesh et al./Nature Nanoscience)
