New light source: A million times brighter than the sun

PhD thesis investigated application of a special white-light laser for semiconductor industry and microbiology

14-Feb-2022 - A new high-performance white-light laser is expected to speed up quality control in the semiconductor industry and provide closer monitoring of toxicity tests in microbiology. In one step, this laser enables the two-sided characterization of surfaces and can be integrated into production chains. ...

Raman Microspectroscopy for Microbiology

Methodology can provide new insights into a variety of key topics in microbiology

17-Jan-2022 - Raman microspectroscopy is a fast and non-invasive technology to determine the chemical composition of living microorganisms in near real-time. Jürgen Popp, scientific director of the Leibniz Institute of Photonic Technology, together with an international team of expert scientists, describes the ...

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

Development of an AI-powered smart imaging system for early-detection and classification of live bacteria in water samples

15-Jul-2020 - 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 ...

Elemental bones

Bone samples could be the ultimate biomarker for environmental pollution

18-Jun-2010 - Exposure to chemical pollutants is of growing concern to regulators, health workers, and environmentalist groups alike. Now, researchers in the US and Russia have demonstrated that samples of human bone can act as a biological marker for dozens of metals and toxic elements across the periodic ...

Researchers validate a technique to detect, in one day, wether or not a patient is suffering from Tuberculosis

08-Oct-2009 - A team headed by Doctor Manuel Casal, head of Microbiology at Reina Sofia Hospital in Cordoba has validated in patients a technique, originally produced by a German company, capable of diagnosing tuberculosis in only one day and determining whether or not it is resistant to two of the drugs used ...

Microscope reveals how bacteria 'breathe' toxic metals

18-Mar-2009 - Researchers are studying some common soil bacteria that "inhale" toxic metals and "exhale" them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio ...

Biologist enhances use of bioinformatic tools and achieves precision in genetic annotation

20-Jan-2009 - José Luis Lavín Trueba, a graduate in biology and biochemistry from the University of Salamanca (Spain) and currently collaborator in the Genetic and Microbiology Research Group at the Public University of Navarre, has enhanced the use of bioinformatic tools for the identification and annotation ...

$2 egg-beater could save lives in developing countries

17-Oct-2008 - Plastic tubing taped to a handheld egg-beater could save lives in developing countries, the Royal Society of Chemistry’s journal Lab on a Chip reports. The low-cost centrifuge replacement can separate plasma from blood in minutes, which is used in tests to detect lethal infectious diseases ...

Sophisticated monitoring array to address mystery of uranium plume

Groundwater contamination remains significantly unchanged for 10 years

19-Sep-2008 - Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been installed ...

Watching DNA Repair in Real Time

25-Sep-2006 - Direct observations of DNA are giving new insights into how genetic material is copied and repaired. "We can monitor the process directly, and that gives us a different perspective," said Roberto Galletto, a postdoctoral scholar at UC Davis and first author on a paper published in Nature. In E. ...
