Sentences with phrase «limits cell size»

New Biophysical Approaches to Cell Biology At the «Organization, Quality Control and Remodeling» minisymposium, Marina Feric, a graduate student in Cliff Brangwynne's lab at Princeton University, presented her work on understanding how gravity limits cell size.

Which is roughly where things stood until last year when Princeton bioengineers Marina Feric and Cliff Brangwynne published a paper in Nature Cell Biology describing their probing of cellular inner space, the cell nucleus, and their discovery that gravity could limit cell size.

Not exact matches

This widespread lack of the need for telomerase is used by evolution as a key component of our defense against cancer, because having a limit to the size and renewal of telomeres prevents our cells from replicating themselves indefinitely — the crucial hallmark of cancer.

Nevertheless, as Tobias says, it is still ``... a field beset with relatively few facts but many theories... The story of early hominid brains has to be read from carefully dated, well identified, fossilised calvariae, or from endocranial casts formed within them... Such materials confine the Hercule Poirot, who would read «the little grey cells» of fossil hominids, to statements about the size, shape and surface impressions... of ancient brains...» The other major limiting factor at the moment is the lack of suitable fossil skulls for such studies.

The performance and stability of inorganic - organic perovskite solar cells are also limited by the size of the cations required for forming a correct lattice.

However, the timing of this shutdown is important because if the competing pathway is necessary for cell growth, turning it off limits the population size, and the bacteria won't produce enough of the desired compound.

Users will be reading eBooks on a myriad of different devices, including but not limited to; cell phones, tablet devices, HD Tvs and desktop computers, all with varying screen resolutions and dpi (dot per inch) sizes.

I know that some models attempt to have dynamic grid cell size, so they only have high resolution where it is needed — this is a nice computational trick that saves time, but is probably limited in applicability.

Like others above, I suspect a cell size of well under 200 km will be needed, maybe even smaller to allow an extrapolation to a limiting case (like the missing exponent in how long is the coastline of Britain, Mandelbrot).

In addition, the power to detect significant differences for small to medium effect sizes was limited because of the relatively small cell sizes, particularly for satisfied couples with a depressed husband.
