Cellular aging: A basic paradox elucidated

In a study published in Nucleic Acids Research, the team of cancer researcher Francis Rodier, an Université de Montréal professor, shows for the first time that cellular senescence, which occurs when aging cells stop dividing, ...

Important aspects of signalling across cell membranes in plants

(PhysOrg.com) -- Every living plant cell and animal cell is surrounded by a membrane that helps it communicate with other cells and the outside world. These cellular membranes contain receptor molecules that serve as the ...

US officials at odds over cellphone use on planes (Update)

It looks like the U.S. government is more conflicted about cellphones on planes than most American travelers. Even as one federal agency considers allowing the calls, another now wants to make sure that doesn't happen.

New biology unveiled for fundamental cellular machinery

Cellular communication relies on receptor molecules on the cell surface. The periodic uptake and sorting of these receptors, critical for their degradation or recycling, are governed by an elaborate machinery prominently ...

Smartphones -- the grip of death

New research by academics in the University of Bristol's Centre for Communications Research has highlighted the problems of reduced sensitivity in wireless communications, along with developing new solutions to overcome the ...

A new low-latency congestion control for cellular networks

Heavy traffic on narrow roads could be one of the leading causes of traffic congestion, which also applies to communication networks. If more data is collected than the allowed data capacity can accommodate, communication ...

Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...
