Who gives stem cells their marching orders?

...activity of this gene in embryonic development may hold the key to finding a way to control its activity in tumor cells. "We need to separate the aspects of Nodal function, and how this protein is regulated by the cell at the molecular level," says Constam. "The embryo holds the key to this understanding....

They hold that it is still an open question as to whether their estimates of discoverable genera mirror the actual diversity of dinosaur genera that walked the earth. Their findings, combined with previous studies suggest that nearly half of all dinosaur gene...

Lost in the labyrinth

...ps organisms manage stem cells, by keeping them on hold and preventing their differentiation until the right time. Such pathways are usually switched on and off by external stimuli that help cells respond properly to the environment. Now Peggy Kirstetter and other members of Nerlov's lab have shown what h...

Rapid-fire jaws propel ants to safety

...l. -- Move aside, mantis shrimp; trap-jaw ants now hold the world record for fastest moving body parts. Scientists using a high-speed imaging system have found that the jaws in trap-jaw ants snap shut in less than a millisecond, averaging a speed of 38 meters per second (approximately 137 kilometers/hour...

Burning wetlands unleash sequestered mercury in wake of climate change

...northern regions will cause soil to relinquish its hold on hundreds of years of mercury accumulation, sending that mercury back into the air at levels considerably higher than previously realized.
