How macrophages regulate regenerative healing in spiny mice      (via sciencedaily.com)     Original source 

A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.

New study unveils how plants control the production of reactive oxygen species      (via sciencedaily.com)     Original source 

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Single-celled kamikazes spearhead bacterial infection      (via sciencedaily.com)     Original source 

You suddenly feel sick -- pathogenic bacteria have managed to colonize and spread in your body! The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and vital cell functions. Before these deadly toxins can attack host cells, bacteria must first export them from their production site -- the cytoplasm -- using dedicated secretion systems.

Glowing COVID-19 diagnostic test prototype produces results in one minute      (via sciencedaily.com)     Original source 

Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.

A novel pathway regulating lipid biosynthesis by fatty acids      (via sciencedaily.com)     Original source 

Sterol regulatory element-binding proteins (SREBPs) play a crucial role in lipid biosynthesis. In a recent study, researchers identified a novel cleavage enzyme of SREBP-1c, a key player in fatty acid biosynthesis. Moreover, the team unveiled, for the first time, that the biosynthesis process of fatty acid in the liver is activated by saturated fatty acids and inhibited by polyunsaturated fatty acids, providing new insights into the intricate workings of this cleavage system.
