Pair of cancer genes found to drive both cell migration and division

...ween two scientific fields that have traditionally kept to themselves. "Scientists studying cell migration have focused on the front of the cell and what drives it, while cell division researchers have concentrated on the furrow within the dividing cell," says Devreotes. "But we've found that when you lo...

Advancements In Genomics Foster Deep Sea Discoveries

...chers grow the microbes in high-pressure cylinders kept cold and dark in Bartlett’s laboratory at Scripps. Bartlett’s past genetic analyses revealed a creature that can sense changes in pressure using a natural barometer-like mechanism, which adjusts the flexibility of its membranes to cope with differen...

Some Brain Cells 'Change Channels' To Fine-tune The Message

... the swap, sodium can still get in, but calcium is kept out. To learn more about how this takes place, the Hopkins researchers studied brain cells from genetically engineered mice. Through their experiments, the researchers determined that the PICK1 and NSF proteins are both required for the calcium-forb...

New lab technique identifies high levels of pathogens in therapy pool

...me ill at the facility. The indoor pool water was kept at temperatures of 92 degrees to 94 degrees F and was treated with hydrogen peroxide rather than chlorine. The team found that pathogens thrived inside hydrogen peroxide bubbles produced at the pool surface and were dispersed as the bubbles became ai...

Key mechanism in genetic inheritance during cell division identified

...it could be the mechanism by which chromosomes are kept segregated during mitosis." Nogales is one of the co-authors of a paper reporting the results of this research which appears in the January 21, 2005 issue of the journal Molecular Cell. Other authors of the Molecular Cell paper were Georjana Barne...

A frog's life is food for thought

...e frogs back to the laboratory where one group was kept in aestivation while the other group were not allowed to aestivate and were fed regularly. "I compared the various aspects of their gut biology and physiology," she said. "We put animals into aestivation and woke them up and fed them to find out ho...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...enerations by an inherited trait." The scientists kept the plants in isolation so they couldn't accidentally crossbreed with plants that didn't have the mutated gene, called hothead, that causes organ fusion like that seen in the flowers. The researchers used molecular markers - bits of DNA that help ide...

Tiny scaffolding allows stem cells to become working fat cells

...urs in normal tissue. So far, the researchers have kept the cells alive and thriving for several months and hope to maintain them for up to a year. "We know that the environment in which a community of cells finds itself has a great deal of influence on the biology underway within those cells," Kniss sai...

Another advantage of SPIM is that the specimen is kept alive in a liquid-filled chamber, allowing scientists to track developmental processes like the formation of eyes and the brain in embryonic fish or other model organisms. The presentation of SPIM at scientific conferences has generated a flood of r...

Wisconsin scientists grow critical nerve cells

...once past a certain point, Li found that the cells kept veering off toward different cellular destinies. After hundreds of unsuccessful variations of growth factors and morphogens, Li was struck by an idea: Why not apply a chemical known to be necessary for a later stage of neuron development to a much ea...
