Why Christmas trees are not extinct

... water into one end of each twig, and then used an electronic balance to weigh water dripping out the other end. Then, based on the number of conduits and valves in twigs and their known dimensions, the biologists calculated the resistance to water flow of both the conduits and the valves. The scientists fou...

DNA self-assembly used to mass-produce patterned nanostructures

...chievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured. Instead of using silicon as the platform for tiny circuits, as is done in the current manufacturing technique of photolithography, the Duke researche...

New battery technology helps stimulate nerves

...indispensable in everything from pacemakers to the electronic stimulators that help restore function in the brains of Parkinson's patients. But lithium batteries don't last forever and new surgery to maintain many devices seeded into the body is required, as it is to replace batteries and devices at the end of...

ASU researchers 'wire' DNA to identify mutations

...all current, or bias is used to probe the internal electronic states of DNA. By measuring the conductance, the team was able to understand the sequence information in the DNA and whether there was a mismatch in comparison to a normal DNA sequence. What they found was that just a single base pair mutation in a...

Differentiation is the process by which embryonic stem cells gradually turn into function-specific types of adult cells or so-called "cell lineages,"...

Nanopore method could revolutionize genome sequencing

...ally different, each base creates its own distinct electronic signature. Previous attempts to sequence DNA using nanopores were not successful because the twisting and turning of the DNA strand introduced too much noise into the signal being recorded. The new idea takes advantage of the electric field that dr...
