The DNA computers – known as origami robots because they work by folding and unfolding strands of DNA – travel around the insect's body and interact with each other, as well as the insect's cells. When they uncurl, they can dispense drugs carried in their folds.
Sharrock's insight:

bots in bugs!

Neuron Light Switch Now Goes “On” and “Off” | MIT Technology Review

Neuron Light Switch Now Goes “On” and “Off” | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it
A new optogenetic protein gives neuroscientists more control over brain circuits.

 

Optogenetics is a recent innovation in neuroscience that gives researchers the ability to control the activity of neurons with light. With this powerful tool, researchers are teasing apart the biological basis of memory, behavior, and disease (see “Scientists Make Mice ‘Remember’ Things That Didn’t Happen” and “An On-Off Switch for Anxiety,”). But for the first several years of this technology’s existence, the proteins that scientists added to neurons to make them react to light were only good at activating neurons. That limited researchers’ ability to understand neuronal circuits, sets of interconnected neurons that are thought to control behavior and, when misfiring, to underlie many brain conditions. Problems can arise from any imbalance in circuit activity, whether too much or too little.

High-pressure cryocooler is local company's new product | Cornell Chronicle

Protein crystallography, which reveals atomic structures of protein crystals using diffracted X-ray beams, is a tricky business. The crystals are delicate; to withstand X-rays, they must be flash-frozen, typically with the addition of cryoprotectants to preserve them. Preparing samples and finding the correct cryoprotectant for each crystal can risk sample damage and months of work.

 
Sharrock's insight:

information: "Gruner’s group has published several scientific papers on the cryocooling technique and other scientists have confirmed their results. Since Gruner’s research is supported in part by the National Institutes of Health via MacCHESS, they became interested in bringing the technology to crystallographers everywhere, and it made sense to try to license it."

Scientists discover double meaning in genetic code

Scientists discover double meaning in genetic code | Science, Technology, and Current Futurism | Scoop.it
Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease.
Sharrock's insight:

"The genetic code uses a 64-letter alphabet called codons. The UW team discovered that some codons, which they called duons, can have two meanings, one related to protein sequence, and one related to gene control."
