Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

...gnals.After showing that the swellings were mostly stable in number and sizeover the course of three to seven days, Brendza injected Abetaantibodies directly onto the surface of the mouse brains. In the regionof the injection, the antibodies cleared the plaques, confirmingearlier research results. Then Bren...

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...

Influenza vaccine uses insect cells to speed development

...ns. "Since all the media used here are chemically stable and commercially available, the process can be easily scaled up for commercial manufacture," says Wang. "New FluBlok vaccines can be developed quickly and safely to address late appearing influenza viruses and to reduce the impact of a potential flu ...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

... freely through the air, is necessary to produce a stable pattern of wing motion and enabled the team to capture X-ray images at different stages of muscle contraction. By combining the technologies, the researchers could reconstruct a ‘movie?of the molecular changes in the powerful muscles as they lengthen...

NIH Calls on Scientists to Speed Public Release of Research Publications

...eral important goals, including: 1. creating a stable archive of peer-reviewed research publications resulting from NIH-funded studies to ensure the permanent preservation of these vital research findings; 2. securing a searchable compendium of these research publications that NIH and its awardees c...

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

...affidi. 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...

Tendency to hair loss inherited from the mother

...develops as a result of the genetic change is more stable and is not broken down so quickly. Both mechanisms can lead to the effect of the androgens becoming greater, which in turn brings about hair loss." The findings are also interesting for the aspect of how hair loss is inherited. The gene for the andr...
