Tomorrow’s tools

22 December 2014

For 2014, rather than compile the ‘top tools and techniques’ — a list certain to include CRISPR and other technical tricks detailed in our weekly Toolboxes — we asked researchers to dream up the next big tool in autism research. Their wishes range from protein sequencers to scanners that can capture brain activity during daily activities.

Calcium sensor leaves permanent mark in activated neurons

by  /  17 November 2014

Researchers have engineered a fluorescent sensor that irreversibly switches from green to red when a neuron fires, thereby serving as a permanent mark of neuronal activation. They described the unpublished work Monday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Autism-linked deletion sparks symptoms via many genes

by  /  23 October 2014

Deletion or duplication of 16p11.2, a chromosomal region linked to autism, may trigger symptoms via the interactions of genes both within and outside the region at a key point in development. Researchers presented these preliminary results Sunday at the 2014 American Society of Human Genetics Annual Meeting in San Diego.

Cluster of symptoms reveals gene’s link to autism subtype

by  /  3 July 2014

CHD8, a gene that regulates the structure of DNA, is the closest thing so far to an ‘autism gene,’ suggests a study published today in Cell. People with mutations in this gene all have the same cluster of symptoms, including autism.

Sophisticated camera captures all firing neurons

by  /  18 June 2014

A new imaging technique can capture the activity of every neuron in a zebrafish larva or a roundworm. Researchers described the method, which is at least ten times faster than others, in Nature Methods.

Close look at autism-linked region reveals complex biology

by  /  27 November 2013

Deletion and duplication of the 16p11.2 chromosomal region have opposite effects on brain size, but produce similar alterations in the brain’s processing of sound. Researchers reported these and other unpublished findings at the 2013 Society for Neuroscience annual meeting in San Diego, painting a complex picture of the region’s role in autism.

Rabies-like virus, robot make contact with single neurons

by  /  14 November 2013

A new technique allows researchers to track the movement of a molecule along a single neuron’s projections. The technique, adapted for zebrafish, was presented Monday at the 2013 Society for Neuroscience annual meeting in San Diego.
