Ready to unlearn

Failure to unlearn the precedence effect.

Studies of the precedence effect using two binaural clicks have shown that listeners' ability to discriminate changes in the interaural time difference (ITD) of the lagging click is much poorer than that for the leading click [e.g., Zurek, J. Acoust. Soc. Am. 67, 952-964 (1980)]. This difference is thought to reflect an auditory process that suppresses directional information from the lagging s...

GLUT4 ready to go

GLUT4 ready to go esicles containing the glucose transporter GLUT4 travel rapidly on a microtubule network that lies just under the plasma membrane in resting cells, according to results from Lizunov et al. (page 481). The vesicles occasionally touch the plasma membrane and, when stimulated by insulin, quickly fuse with it. GLUT4 is sequestered in vesicles in resting cells. Insulin exposure ind...

Teleglaucoma: ready to go?

Telemedicine technologies and services allow today's ophthalmic clinicians to remotely diagnose, manage and monitor several ophthalmic conditions from a distance. But is this the case for glaucomas? There has been a proliferation of telemedicine friendly devices in recent years that improves the capabilities of the clinician in managing glaucomas. The existing instruments still need to align th...

Ready to replicate? So vesiculate!

ells that passively swell and contract with changes in osmolarity are the key to detecting those changes, say Most cells have at least two mechanisms for maintaining homeostasis in response to changes in salt concentrations. Without these mechanisms, osmotic forces take over: more water and thus less salt outside cells leads water to flood into a cell. But this swelling doesn't occur in most ce...
