Cell-to-Cell Communication: More is Better — Up to a Point
January 20, 2016 | Yale UniversityEstimated reading time: 2 minutes
“They need to ‘talk’ to each other to interpret the signal, but talking is a noisy process,” said Levchenko, comparing it to the din of a crowded party. “It’s hard to hear what’s happening on the other side of the room. Friends can pass on a message for you, but it gets distorted in all the noise, as in a game of ‘telephone.’ It’s like the famous adage, but with a twist: Bigger is better, but only to a degree.”
How cells communicate is crucial to many biological processes, and could have profound implications for the treatment of breast cancer. Growth factor gradients frequently guide breast cancer cells as they invade surrounding tissues, so understanding the influence of collective cell responses is critical to developing new treatments, said the researchers.
Other impacts extend beyond biology. As electronic circuits get smaller and noisier, the semiconductor industry has increasingly become interested in cellular biology, and in how coupled cell circuits can support information processing. The National Science Foundation, National Institutes of Health, and the Semiconductor Research Corporation provided funding for the study.
Levchenko also is a member of the Yale Cancer Center.
The other principal investigators of the studies are Andrew Mugler and Andrew Ewald of Johns Hopkins University and Ilya Nemenman of Emory University.

Growth Potential: Electronics Manufacturing Driving Massive Surge in Manufacturing Investment
04/22/2024 | Shawn DuBravac, IPCIn the early months of the pandemic, investment in manufacturing infrastructure, such as plants and production facilities, declined sharply. Real investment dropped over 11%, before finally recovering to pre-pandemic levels in the first half of 2022. Over the past two years, however, several factors have combined to drive manufacturing investment to record levels.
Digitalisation and ESG
04/19/2024 | Marina Hornasek-Metzl, AT&SDigitalisation and ESG are prominent and high-priority topics in the global business community. The first focuses on applying technology throughout the value chain to produce faster, smarter, and more desirable business outcomes. The latter emphasises the broader value a business is expected to create for its stakeholders from an environmental, social, and governance perspective.
Designing Electronics for High Thermal Loads
04/16/2024 | Akber Roy, Rush PCB Inc.Developing proactive thermal management strategies is important in the early stages of the PCB design cycle to minimize costly redesign iterations. Here, I delve into key aspects of electronic design that hold particular relevance for managing heat in electronic systems. Each of these considerations plays a pivotal role in enhancing the reliability and performance of the overall system.
