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.....»»
Researchers design novel microfluidic module for controlling the porosity of manufactured materials
Porous materials are essential for many chemical processes, such as light harvesting, adsorption, catalysis, energy transfer, and even new technologies for electronic materials. Therefore, many efforts have been made to control the porosity of differ.....»»
Chemical labeling method provides new approach for recording cellular activities
In living cells, a vast number of transient events occur simultaneously, each of them important for a given cell in carrying out its function. The faithful recording of these transient activities is a prerequisite for a molecular understanding of lif.....»»

Pharmacists propose ways to increase the activity of levofloxacin and overcome bacterial resistance
The antibacterial drug levofloxacin is used to treat pneumonia, sinusitis, genitourinary infections, and other diseases. It is included in the WHO Model List of Essential Medicines. In terms of its chemical structure, it is a third-generation fluoroq.....»»
Fire is a chemical reaction—here"s why Australia is supremely suited to it
Over the last 15 million years, Australia has slowly dried out. After humans arrived more than 65,000 years ago, they learned to use fire to their advantage. Today, fire weather is getting more frequent—and fires are following as the world heats up.....»»
Antibiotic use on Kenya"s dairy farms is putting consumers and animals at risk
Farmers often use antibiotics to keep their livestock healthy. They're sometimes used as "quick fixes", to avoid more costly management measures like regular disinfection, waste management, routine vaccination or provision of clean drinking water......»»
Scientists create method to bond hydrogels and other polymeric materials using chitosan
Hydrogels are versatile biomaterials conquering an increasing number of biomedical areas. Consisting of water-swollen molecular networks that can be tailored to mimic the mechanical and chemical features of various organs and tissues, they can interf.....»»
Natural pesticides gain ground in "agri-tox" capital Brazil
Inspecting a thriving green field, Brazilian farmer Adriano Cruvinel is beaming: Using a fraction of the chemical products he used to, he is growing even more soy, thanks to natural pesticides......»»
