• Aviation safety: Rapid test for harmful microbes in kerosene developed
  

  Fuels such as kerosene or diesel can be contaminated by fungi or bacteria. The microorganisms settle in the liquid itself, on the inner walls of tanks and pipes or in fuel filters and feed on carbon atoms. Since the fungi and bacteria multiply well in this environment, they can form a streaky biofil more

• Natural UV radiation in winter not strong enough against SARS-CoV-2
  

  The SARS-CoV-2 virus that causes COVID-19 poses a threat to human health both indoors and outdoors. Besides direct infection from respiratory droplets and aerosols, another mode of transmission involves airborne viruses that linger in the air before settling on and contaminating surfaces. A recently more

• Deep learning enables early detection and classification of live bacteria using holography
  

  Waterborne diseases affect more than 2 billion people worldwide, causing substantial economic burden. For example, the treatment of waterborne diseases costs more than $2 billion annually in the United States alone, with 90 million cases recorded per year. Among waterborne pathogen-related problems, more

Microbots zoom around water, destroying bacteria

One day, the tiny robot you see here could help clean up contaminated water. In places where potable sources are scarce, they can destroy disease-causing bacteria in its path and unlike conventional disinfectants, the microbots can be removed easily with a magnet. more

• Automated workflow for the determination of fatty acid methyl esters (FAME) in fat and fat containing food samples using a 90 sec. transesterification
  

  The analysis of oils, fat and fat contain- ing food containing food via fatty acid methyl esters (FAME) is a common task in governmental, quality control (QC) or contract research laboratories (CRO). Most often the samples are processed manually, whi more

• Removing contaminants from databases of draft genomes

  by Jennifer Lu, Steven L. Salzberg Metagenomic sequencing of patient samples is a very promising method for the diagnosis of human infections. Sequencing has the ability to capture all the DNA or RNA from pathogenic organisms in a human sample. However, complete and accurate characterization of t more

• NASA Curiosity rover hits organic pay dirt on Mars

  Since NASA's Curiosity rover landed on Mars in 2012, it has sifted samples of soil and ground-up rock for signs of organic molecules—the complex carbon chains that on Earth form the building blocks of life. Past detections have been so faint that they could be just contamination. Now, samples taken more
