Why does Mercury have such a big iron core? Magnetism!
A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of ou.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Affordable iron catalysts offer a sustainable route to prized Z-alkenes
Chemists from the National University of Singapore (NUS) have developed an iron-catalyzed method that overcomes a significant challenge in the sustainable synthesis of trisubstituted Z-alkenes by inserting two alkyl chemical groups into a type of com.....»»
Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called.....»»
