(Phys.org)—Gene expression plays a central role in the orchestration of virtually all cellular processes. While inducible promoters have proven invaluable in understanding regulatory networks by modifying gene expression ...
Since artificial intelligence pioneer Marvin Minsky patented the principle of confocal microscopy in 1957, it has become the workhorse standard in life science laboratories worldwide, due to its superior contrast over traditional ...

Biological tissues are built when cells anchor to specific sites on a 3-D microfiber network in an extracellular matrix (ECM). Scientists are keen to recreate biological tissues in the lab using bioinspired tissue engineering ...
Fireflies, heart cells, clocks, and power grids all do it—they can spontaneously sync up, sending signals out in unison. For centuries, scientists have been perplexed by this self-organizing behavior, coming up with theories ...

(Phys.org)—Synthetic biology is a multi-disciplinary field that applies engineering techniques to biological systems. While the foundations of synthetic biology were laid in the 1990s with the burgeoning of genomics and ...
(Phys.org) —Fluorescence imaging is the most widely used method for analyzing the molecular composition of biological specimens. Target molecules, when they are present, can be "tagged" with a fluorescent label and made ...
