Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Did this chemical reaction create the building blocks of life on Earth?
How did life begin? How did chemical reactions on the early Earth create complex, self-replicating structures that developed into living things as we know them?.....»»
Microbes could help reduce the need for chemical fertilizers
Production of chemical fertilizers accounts for about 1.5% of the world's greenhouse gas emissions. MIT chemists hope to help reduce that carbon footprint by replacing some chemical fertilizer with a more sustainable source—bacteria......»»
Using dust to bust crime scene DNA forensics
An airborne fraction of soil, or dust, contains biological and chemical "signatures" that act as a fingerprint to a specific location. Australian forensic science experts, led by Flinders University, have highlighted the usefulness of the latest tech.....»»
Researchers construct modularized catalytic system for transfer hydrogenation
The precise catalytic conversion of chemical bonds is a paramount goal in catalysis. Enzymes, as efficient biocatalysts, are well known for their high catalytic activity, selectivity, and substrate specificity under mild reaction conditions, which ca.....»»
Exposing plants to an unusual chemical early on may bolster their growth and help feed the world
Just like any other organism, plants can get stressed. Usually it's conditions like heat and drought that lead to this stress, and when they're stressed, plants might not grow as large or produce as much. This can be a problem for farmers, so many sc.....»»
Scientists flag conflicts of interest ahead of UN plastic and chemical talks
An international group of 35 scientists is calling out conflicts of interest plaguing global plastic treaty negotiations and that have interfered with timely action on other health and environmental issues. They urge the implementation of strict guid.....»»
Liquid metals shake up century-old chemical engineering processes
Liquid metals could be the long-awaited solution to "greening" the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century......»»
New simulation program offers way to build microbial cell factories quickly and efficiently
As climate change and environmental concerns intensify, sustainable microbial cell factories garner significant attention as candidates to replace chemical plants. To develop microorganisms to be used in the microbial cell factories, it is crucial to.....»»
"Superbugs" with hypervirulence and carbapenem resistance in Klebsiella pneumoniae
A new bacterial threat, the carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP), is rapidly spreading in clinical environments in China, posing a significant public health challenge. This pathogen is simultaneously multidrug-resistant,.....»»
How do bacteria actually become resistant to antibiotics?
"What doesn't kill me makes me stronger," originally coined by Friedrich Nietzsche in 1888, is a perfect description of how bacteria develop antibiotic resistance......»»
The cell"s "read–write" mechanism: Researchers uncover how instructions for gene expression are relayed
The "read–write" mechanism by which cells replicate and use chemical instructions for expressing genes has been uncovered by RIKEN researchers. The quality and quantity of gene expression correlates not only with instructions by transcription facto.....»»
Researchers develop stable and efficient inorganic CsPbI3 solar cells
The chemical and thermal stable inorganic cesium lead triiodide (CsPbI3) perovskite has shown great potential for photovoltaic applications. DMAPbI3 (dimethylammonium [DMA]) or "HPbI3"-assisted crystallization is effective for the preparation of high.....»»
