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.....»»
Green and digital transitions are putting environmental problems on the back burner, says study
The European Green Deal is a package of political initiatives to ensure that the EU reaches climate neutrality by 2050. Faced with this challenge, the parallel goals of the green and digital transitions are at the center of the European Commission's.....»»
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.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Hyte Keeb TKL review: a keyboard for the fans
You'll have some strong reactions to the design of the Hyte Keeb TKL, but there's no denying that it's an excellent gaming keyboard......»»
Some people insist the Tijuana River is poisoning them: Officials disagree
The Tijuana River should not be flowing this time of year. But throughout the dry season, it has—delivering millions of gallons a day of an unnatural mix of water, neon green sewage and industrial waste from Tijuana through the city of Imperial Bea.....»»
