Novel nanospectroscopy measures biomolecular changes induced by drugs in human cells Kumar Jeetendra | July 20, 2020 Synchrotron InfraRed Nanospectroscopy has been used for the first time to measure biomolecular changes caused by a drug (amiodarone) in human cells (macrophages) and localized at 100 nanometre scale, i.e. two orders of magnitude smaller than the IR wavelength used as probe. This was achieved at the Multimode InfraRed Imaging and Micro-Spectroscopy (MIRIAM) beamline (B22) …
Designers develop plant-based splash that could be utilized in N95 mask filters Kumar Jeetendra | October 7, 2020 Engineers have invented a way to spray extremely thin wires made of a plant-based material that might be used in N95 mask filters, devices that harvest energy for electricity, and potentially the production of human organs. The procedure involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging …
Researchers devise new technique to plan HIV’s sweet shield in remarkable detail Kumar Jeetendra | October 26, 2020 Scientists from Scripps Research and Los Alamos National Laboratory have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules which help protect HIV from the immune system. Mapping these shields will give researchers a more comprehensive comprehension of why dinosaurs respond to some spots on the virus but not others, …
Engineered counter acting agent may forestall Covid from contaminating human cells Kumar Jeetendra | November 4, 2020 By screening hundreds of artificial antibodies, researchers at Karolinska Institutet in Sweden and EMBL Hamburg in Germany have identified an antibody that may prevent the new coronavirus from infecting human cells. The analysis, which is printed in the journal Nature Communications, also reveals how electrons can be quickly generated in the event of future pandemics. …
A short-reduce in photosynthetic equipment can permit needles of pine bushes to live green Kumar Jeetendra | December 24, 2020 How do conifers which are used for example as Christmas trees keep their green needles over the boreal winter when many trees drop their leaves? Science hasn’t provided a good response to this question but now an international group of scientists, including researchers in Umeå University, has deciphered that a short-cut in the photosynthetic machinery …
Researchers find out how shattered chromosomes make most cancers cells greater aggressive Kumar Jeetendra | December 27, 2020 Cancer is one of the world’s biggest health afflictions because, unlike some diseases, it’s a moving target, constantly evolving to evade and resist treatment. In a paper published in the December 23, 2020 online dilemma of Nature, researchers at University of California San Diego School of Medicine and the UC San Diego branch of the …
Scientists disentangle the cycle that makes virus irresistible Kumar Jeetendra | January 9, 2021 Researchers have for the first time identified how viruses like the poliovirus and the common cold virus’package up’ their genetic code, allowing them to infect cells. The findings, published today (Friday, 8 January) in the journal PLOS Pathogens by a team from the Universities of Leeds and York, open up the possibility that medication or …
New fluorescence microscopy strategy produces nanoscale 3D pictures of living cells Kumar Jeetendra | January 12, 2021 A new fluorescence microscopy technique has produced the world’s first nanoscale 3D images of molecules in a whole, living cell, researchers at KTH Royal Institute of Technology reported. Ilaria Testa, an associate professor at KTH and researcher at the Science for Life Laboratory, says the technique is capable of generating images with precision that until …
Recently recognized supplement helps the gut review earlier diseases and execute attacking bacteria Kumar Jeetendra | January 17, 2021 Scientists studying the body’s natural defenses against bacterial disease have identified a nutritional supplement –taurine–that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could help efforts seeking alternatives to antibiotics. …
Bacteria responsible for seafood related stomach disturbs can go torpid and “wake up” Kumar Jeetendra | January 20, 2021 Vibrio parahaemolyticus is a marine bacterium that can lead to gastroenteritis in humans when eaten in raw or undercooked shellfish such as oysters and mussels. Some of these bacteria have the ability to turn dormant in poor growth conditions such as cold temperatures – and can stay in that state of hibernation for long periods …
Revelation may decrease the ecological effect of chemical manufacturing Kumar Jeetendra | February 7, 2021 Chemical manufacturers frequently use toxic solvents such as alcohols and benzene to make products such as pharmaceuticals and plastics. Researchers are analyzing a previously overlooked and misunderstood phenomenon in the chemical reactions used to make these products. Combining metal and ore nanoparticles hastens many chemical reactions and helps maximize yield and profit margins for the …
Small SARS-CoV-2 protein may have huge ramifications for future COVID-19 medicines Kumar Jeetendra | April 12, 2021 A very small protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future therapies, according to a team of Penn State researchers. Using a novel toolkit of approaches, the scientists uncovered the first full structure of the Nucleocapsid (N) protein and discovered how antibodies from COVID-19 patients interact with …
