Examining the role of development in evolutionary theory

In an editorial titled "Introduction to the Special Issue: Development, Evolution, and Movements toward Resynthesis," the authors underscore a shift towards acknowledging the importance of individual development in evolutionary change. This shift challenges traditional Darwinian and neo-Darwinian frameworks while advocating for an Extended Evolutionary Synthesis. The introduction was penned by Dr. David Witherington, Dr. Robert Lickliter, and Dr. David Moore and published by Karger.

Global regulators key to bacterial adaptation on surfaces

A recent study published in PLOS Biology by Dr. Martin Ackermann and his team has shed light on the rapid evolution of surface-bound bacteria. The researchers found that mutations in key global regulators such as RicT, RNAse Y, and LexA trigger significant shifts in gene expression, influencing nearly half of all genes. This process ultimately shapes the bacteria's adaptive strategies for colonizing and expanding on surfaces.

Inorganic nitrogen exchange discovered to be pathway for microbial communication in marine ecosystems

A recent study has revealed that the interactions between algae and bacteria in oxygen-rich marine environments depend on the exchange of inorganic nitrogen compounds, such as nitrite and nitric oxide. These compounds act as signaling molecules, initiating a cascade that triggers algal cell death. This process could potentially contribute to the sudden collapse of oceanic algal blooms. The research was conducted by Dr. Adi Abada, Dr. Roni Beiralas, among others, and published in the ISME Journal.
