Published This is how highly resistant strains of fungi emerge
(via sciencedaily.com) Antibiotic resistance is a matter of common knowledge. And the same phenomenon also occurs with drugs against pathogenic fungi. What causes it is still not very well understood.
Published Optical imaging of dynamic interactions between molecules in a cell
(via sciencedaily.com) Researchers develop the 'photoswitching fingerprint analysis'. A unique technology that for the first time allows the analysis of molecular processes and the regulation of individual proteins in living cells with sub-10 nm spatial resolution. The application ranges from biological to medical research.
Published New bioremediation material to clean up 'forever chemicals'
(via sciencedaily.com) Original source A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed. The material has potential for commercial application for disposing of PFAS, also known as 'forever chemicals.'
Published Wine-drinkers of the world rejoice! New research finds key to billion-dollar problem
(via sciencedaily.com) Original source Grapevine Trunk Diseases, or GTDs, are the bane of vineyard owners worldwide, and as of 2012, were responsible for more than $1.5 billion in annual economic damages. While researchers have long known that a host of pathogenic fungi combine to gang up on grapevines, the mechanics of how these GTD-causing fungi work has remained a mystery.
Published Sniffing out your identity with breath biometrics
(via sciencedaily.com) Researchers have developed an artificial 'nose' that can identify individuals from their breath. Built with a 16-channel sensor array that can detect different compounds found in a person's breath, the olfactory sensor system has the potential to become another option in the biometric security toolkit. Combined with machine learning, the 'artificial nose' was able to authenticate up to 20 individuals with an average accuracy of more than 97%.
Published Sensor imperfections are perfect for forensic camera analysis
(via sciencedaily.com) In a project aimed at developing intelligent tools to fight child exploitation, computer scientists have developed a system to analyze the noise produced by individual cameras. This information can be used to link a video or an image to a particular camera.
Published Radio waves for the detection of hardware tampering
(via sciencedaily.com) Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.
Published Bluetooth signals can be used to identify and track smartphones
(via sciencedaily.com) A team of engineers has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals' movements.
Published Forensic scientists improve touch DNA collection methods
(via sciencedaily.com) Skin cells and their DNA varies between individuals, but new data shows that some groups of people have higher variability in their cell deposits. The South Australian forensic science researchers are building a suite of new insights into crime scene investigation -- including the difference between high, intermediate and low skin 'shedders' that will help understanding of trace or 'touch DNA'.
Published Turning any camera into a polarization camera
(via sciencedaily.com) Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras. The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel.
Published Creutzfeldt-Jakob disease treatment shows promising early results
(via sciencedaily.com) A promising new treatment for Creutzfeldt-Jakob disease (CJD) has shown 'very encouraging' early results following its use in six patients.
Published Real-world study shows the potential of gait authentication to enhance smartphone security
(via sciencedaily.com) A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.
Published Endangered deer's prion gene could protect it from chronic wasting disease
(via sciencedaily.com) China's Père David's deer was nearly gone in the late 1800s. Just 18 deer -- the very last of their kind -- were brought into captivity after the rest had been hunted to extinction. When 11 of the deer reproduced, the species had a chance. Today, after centuries of reintroductions and breeding under human care, the population sits at around 3,000. It's a success story. But that success could come crashing down if chronic wasting disease (CWD) were to infect the population.
Published Bulletproof fingerprint technology takes images in the round
(via sciencedaily.com) Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic methods.
Published Securing data transfers with relativity
(via sciencedaily.com) To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.
Published Solid, liquid, or gas? Technique quickly identifies physical state of tissues and tumors
(via sciencedaily.com) Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more solid may be relatively stable, whereas more fluid-like growths could be more prone to mutate and metastasize.
Published Many US adults worry about facial image data in healthcare settings
(via sciencedaily.com) Uses of facial images and facial recognition technologies -- to unlock a phone or in airport security -- are becoming increasingly common in everyday life. But how do people feel about using such data in healthcare and biomedical research?
Published How proteins help yeast adapt to changing conditions
(via sciencedaily.com) Proteins in the brain called prions are well known for their involvement in causing disease, but a new study suggests they may help yeast cope with rapidly changing environmental conditions.
Published New DNA-based chip can be programmed to solve complex math problems
(via sciencedaily.com) A novel chip automates the reaction cascades occurring between molecules inside DNA to carry out complex mathematical calculations.
Published Atomic-level imaging of lethal prions provide sharpened focus for potential treatments
(via sciencedaily.com) The highest-ever resolution imaging of an infectious prion provides the first atomic-level data of how these abnormal proteins are assembled to cause fatal neurodegenerative diseases in people and animals -- and how they can be potentially targeted by new therapies.
