Abstract:
With the launch of four new sections, Science Signaling continues to leverage online media to maximize scientific communication and discovery. The editors explain exciting recent discoveries in Podcasts, allowing users to tune-in for a portable and understandable summary of cell signaling research. Meeting Reports and Presentations join the Events calendar in the Community section to bring cell signaling highlights beyond the doors of the auditorium. Through collaboration with GrantsNet, Science Signaling brings a list of Funding Sources for cell signaling researchers.

Hearing
Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...
Auditory Perception
Perception of Sound Waves
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...
Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
Sound Waves
Sound waves are longitudinal in most fluids because fluids cannot sustain any lateral pressure. In solids, however, shear forces help in propagating the disturbance in the lateral direction as well. Hence,...
