Open microfluidic and nanofluidic systems

...tant morphology regime is (F) which corresponds to stable filaments. Since this regime covers a relatively small region of the morphology diagram, it can only be obtained if one carefully matches the channel geometry with the substrate wettability. Thus, a water filament in a narrow channel that has a width...

Nano-Probes Allow an Inside Look at Cell Nuclei

...d by a laser. Because these fluorescent probes are stable and nontoxic, they have the ability to remain in a cell's nucleus -- without harming the cell or fading out -- much longer than conventional fluorescent labels. This could give biologists a ringside seat to nuclear processes that span several hours o...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...As the neuron matures, some of these branches form stable synapses while others recede. This trial-and-error process is what establishes the final interconnected mesh of the brain. Because the group could see the full branching structure of a neuron each time it fired, they could watch the branches grow an...

Super predators and mass extinctions

...prey population waxes and wanes. Inevitably, their stable community is disrupted when mutations lead to a super predator that quickly decimates the prey population, which in turn leads to its own demise. The few creatures that survive the predatory apocalypse gradually mutate to fill the existing ecological...

Anammox bacteria produce nitrogen gas in oceans' snackbar

The discovery of anammox bact...

Activation of thermoreceptors mediates raw garlic's burning pungency

...ungency. Allicin is converted to a variety of more stable sulfide compounds over time or with heating, in correspondence with the significantly milder taste of roasted garlic. Garlic's pungency most likely evolved as a defense mechanism against browsing by animals, and indeed many animals--though clearly n...

Cellular Defects in Premature Aging Disease are Reversible

The NCI researchers designed a chemically stable DNA oligonucleotide ?a short DNA sequence that the cell wouldn't be able to degrade ?that would bind to the mutant splice site and prevent the splicing machinery from cutting in the wrong place. "You can think of it as a molecular Band-Aid®," said Mi...
