Longstanding theories of how plants rely on calcium waves to respond systemically to wounding and other stresses have been given fresh perspective. https://phys.org/news/2022-10-science-register-trauma-precursor-calcium.html Plants & Animals Fri, 21 Oct 2022 14:00:01 EDT news585561974 Many biological processes in plants are similar to humans: Cells and tissues in grain plants, including maize, also communicate through electrical signals. The shape and frequency of these signals communicate different things. For example, they signal plants to respond to heat and cold, excessive light intensities or insect pests. https://phys.org/news/2019-06-vacuoles-electrical.html Plants & Animals Fri, 14 Jun 2019 07:57:19 EDT news479717828 Researchers at Duke University have discovered a way to enhance the effectiveness and safety of sonogenetics or ultrasonic modulation, emerging techniques that use sound waves to control the behavior of individual neurons or to promote tissue growth and wound healing in other cells. https://phys.org/news/2018-01-microbeads-ultrasonic-cells-safely.html Biotechnology Tue, 02 Jan 2018 10:43:44 EST news434112214 For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. https://phys.org/news/2014-04-calcium-roots.html Biotechnology Thu, 03 Apr 2014 16:59:53 EDT news315763159 Research based at Princeton University has revealed that newly fertilized cells only narrowly avoid degenerating into fatal chaos. At the same time, scientists have discovered that embryos have acquired a mechanism to contain this dangerous instability, a finding that could help biologists unravel other mysteries about the first hours of life. https://phys.org/news/2011-08-early-life-embryo-monster-lurks.html Cell & Microbiology Mon, 22 Aug 2011 12:03:56 EDT news233233391
