Chemical cocktail in skin summons disease-spreading mosquitoes
Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now......»»
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.....»»

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.....»»
New hazard maps may predict rust disease in loblolly pine trees
New models developed by University of Georgia researchers may help guide the fight against rust disease, according to a new study. The paper is published in the journal Forest Ecology and Management......»»
"Tamed" molecules for more sustainable catalysts: Chemists succeed in synthesizing a spectacular gallium compound
Catalysts play an important role in the manufacture of many products that we encounter in everyday life—for example in cars for exhaust gas purification or in the chemical industry in the production of fertilizers. Catalysts ensure that these react.....»»
Biologists sequence proteins by pulling them through nanopores
A team of chemical biologists at the University of Washington, working with colleagues at Oxford Nanopore Technologies, has developed a protein sequencing process that involves pulling proteins through nanopores in a lipid membrane. Their paper is pu.....»»

Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
Better than blood tests? Nanoparticle potential found for assessing kidneys
In a study published July 29 in Advanced Materials, University of Texas at Dallas researchers found that X-rays of the kidneys using gold nanoparticles as a contrast agent might be more accurate in detecting kidney disease than standard laboratory bl.....»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
