Fingerprint scanner: it only takes 10 minutes to complete drug monitoring, with the accuracy up to 99% The latest research results show that the revolutionary intelligent fingerprint scanner developed by Cambridge company can analyze the sweat of the living or the dead in just 10 minutes, and detect cocaine, marijuana, heroin and other frequently abused drugs or dependent drugs, with the accuracy up to 99% The accuracy of traditional blood and urine detection is only 86% - 92% Https:// - opiates.html the new tool significantly improves the identification rate of peptide mass spectrometry It can improve the quantity and quality of mass spectrometry data analysis and is expected to become the main tool of proteomics daily data analysis Relevant achievements were published online recently in Nature Biotechnology The new generation of open search engine, open pfind, uses the open search process based on sequence label index to scan protein database quickly and identify some high-quality spectra In this process, unexpected modification, mutation, semi-specific and non-specific peptide segments are all in the search space of the engine Open pfind mines the feature information in the data through the peptide spectrum matching and re scoring algorithm based on support vector machine, and carries out the second fine search accordingly Https:// new coating can effectively reduce any surface temperature Yang Yuan and Yu Nanfang, Department of Applied Physics and applied mathematics, Columbia University The team published the latest research results in a new issue of American science magazine They developed a new material, which is a multi-scale micro nano pore structure of "polyvinylidene fluoride hexafluoropropylene copolymer" The film made of this material has a high reflectivity of 96% to 99.6% in the solar band, and 97% in the infrared radiation window High emissivity, in the daytime without electricity to achieve refrigeration Yang Yuan said that the surface of buildings often has requirements for color This material can be combined with pigments to present different colors and reflect the near-infrared light in the sun Compared with traditional coatings, it can significantly reduce the temperature of buildings Https:// the new method can monitor the single molecule in the micro blood in real time Recently, Giovanni maglia, an associate professor of chemical biology from the University of Groningen in the Netherlands, designed a nanopore system that can simultaneously measure different metabolites in various biological fluids in a few seconds Electrical output signals can be easily integrated into electronic devices for home diagnosis The results were published in nature letters Generally speaking, the measurement of many metabolites or drugs in vivo is complex and time-consuming, and it is usually impossible to carry out real-time monitoring Therefore, the ion current through a single nanopore has a high prospect to replace the standard biochemical analysis Https:// studies have found that marijuana can cause more damage to the brain of teenagers than alcohol A new study in the American Journal of psychiatry found that marijuana can bring more risk to the brain development of teenagers than alcohol In the analysis of four key parts of young teenagers' memory- Problem solving, long-term memory, short-term memory, short-term and long-term consequences of marijuana found in cessation behaviors are all more serious Researcher Professor of psychiatry Patricia conrod believes the findings will help explain the phenomenon that young marijuana users are at greater risk of addiction in later life https://
