Ben-Gurion University researchers discover new principle in optics
01-Jun-2023
The Pacific Cleaner Shrimp may hold the secret to keeping white bread white. Inorganic nanoparticles such as titanium dioxide and zinc oxide are widely used as whitening agents in foods, cosmetics, and paints. However, due to health concerns, there is currently an intensive search to find ...
Groundbreaking technique using a new kind of focussing lens overcomes previous X-ray imaging limitations
01-Jun-2023
A pollen grain showing the nanofoam within or a diatom with the individual geometric structures inside clearly visible: Using high-energy X-rays from the PETRA III synchrotron light source at DESY, a team led by CFEL scientists Saša Bajt and Henry Chapman has managed to image these structures ...
New approach represents a paradigm shift in the application of mechanochemical processes in organic chemistry
31-May-2023
Before their approval, pharmaceuticals not only have to be tested for their effectiveness and safety, but also for their stability, since they are usually stored in pharmacies and private households for years and are not allowed to change. To test their stability, a process is needed that ...
A study with the participation of IDAEA and IGME locates organic contaminants derived from human activity in inland and coastal waters of the frozen continent
30-May-2023
Human activity is negatively impacting Antarctic water quality. This is the conclusion of a study carried out by the Institute of Environmental Diagnosis and Water Studies (IDAEA-CSIC) and the Geological and Mining Institute of Spain (IGME-CSIC), in collaboration with the University of Granada ...
Improving the fluid flow inside noselike chambers can enhance detection of harmful chemicals
25-May-2023
Volatile organic compounds are chemicals emitted as gases that can have adverse health effects. They are often found in paints, pharmaceuticals, and refrigerants, among other common products, but they can also act as markers of explosives, insect infestation, food spoilage, and disease. Tracing ...
Sensitive, reliable and durable sensors created for multiple industries
25-May-2023
Extreme environments in several critical industries – aerospace, energy, transportation and defense – require sensors to measure and monitor numerous factors under harsh conditions to ensure human safety and integrity of mechanical systems. In the petrochemical industry, for example, pipeline ...
Researchers programmed a tool that accurately recognises and picks proteins in electron cryo-tomography, substituting troublesome hand selection
24-May-2023
Electron cryo-tomography (cryo-ET) is emerging as a powerful technique to provide detailed 3D images of cellular environments and enclosed biomolecules. However, one of the challenges of the methodology is the identification of protein molecules in the images for further processing. A research ...
Scientists develop effective method to genetically modify brain organoids
23-May-2023
Primates are among the most intelligent creatures with distinct cognitive abilities. Their brains are relatively large in relation to their body stature and have a complex structure. However, how the brain has developed over the course of evolution and which genes are responsible for the high ...
This method offers a wide range of potential applications
22-May-2023
Enzymes are the molecule factories in biological cells. However, which basic molecular building blocks they use to assemble target molecules is often unknown and difficult to measure. An international team including bioinformaticians from Heinrich Heine University Düsseldorf (HHU) has now taken ...
"With our specially developed algorithm, we are three times faster"
22-May-2023
Until now, the analysis of crystalline microstructures in metallic materials has been technically challenging and particularly time-consuming. Researchers from the fields of materials engineering and computer science have now developed an algorithm for this purpose and published it in the ...
