How to steer a moving cell

...make up the compass are functionally integrated to steer the cell under normal and pathological conditions. "A surprising finding was that many of the proteins identified in the neuronal network, the ‘wiring diagram?that controls early development of neural networks in the embryo, are also found to cont...

Advance helps explain stem cell behavior

... the "DNA-binding transcription factors" that help steer stem cells into forming the wide variety of cells that ultimately make up all the organs and parts of a living vertebrate animal. The findings were made using mouse embryonic spinal cord as a model, and will be announced this week in Proceedings of...

Immune system police learn early and sometimes badly

...invaders. It also means one day physicians might steer early education of regulatory T cells in the thymus as a way to vaccinate children against diseases such as lupus, arthritis and type 1diabetes. Or, they might add regulatory T cells to improve the mix in people who already have some bad police. "W...

Stimulation of the semicircular canals can artificially control human walking and balance

...ability to produce illusions of movement, and then steer and balance the body by external control, leads the researchers to expect that stimulation techniques developed from the approach used in the new study will lead the way to diagnostic, therapeutic, and virtual-reality applications. ...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

... needed to revive severely exhausted fisheries and steer survivors into more sustainable livelihoods than fishing. According to new analyses by the Malaysia-based WorldFish Centre (see ? Rebuilding Boats May Not Equal Rebuilding Livelihoods and ? Rehabilitating Livelihoods in Tsunami-Affected Coastal Comm...

Anthrax stops body from fighting back, study shows

...opped the protein actin from building filaments to steer the neutrophils, stopping the body's immune response, the study found. "Neutrophils crawl around in the body and roll around in the bloodvessels and whenever they sense bacteria, they gobble it up likePac-Man," said Russell During, a graduate studen...

Wisconsin scientists grow critical nerve cells

...hat provide the exact growing conditions needed to steer the cells down the correct developmental pathway. "You need to teach the [embryonic stem cells] to change step by step, where each step has different conditions and a strict window of time," says Zhang. "Otherwise, it just won't work." To differenti...
