A special laser system has been developed, using two slightly different frequency combs. This allows for chemical analysis on tiny spaces -- it is a millimeter-format chemistry lab. With this new patent-pending technology, frequency combs can be created on a single chip in a very simple and robust manner.
Fingerprint authentication systems are a widely trusted, ubiquitous form of biometric authentication, deployed on billions of smartphones and other devices worldwide. Yet a new study reveals a surprising level of vulnerability in these systems. Using a neural network trained to synthesize human fingerprints, the research team evolved a fake fingerprint that could potentially fool a […]
Laser-based 'optical tweezers' could levitate uranium and plutonium particles, thus allowing the measurement of nuclear recoil during radioactive decay. This technique provides a new method for conducting the radioactive particle analysis essential to nuclear forensics
Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. The advancement could help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and […]
Combining multiple poor quality CCTV images into a single, computer-enhanced composite could improve the accuracy of facial recognition systems used to identify criminal suspects, new research suggests.
A multidisciplinary team of researchers has developed a portable, easy-to-use device for quick and accurate screening of diseases. This versatile technology platform called enVision (enzyme-assisted nanocomplexes for visual identification of nucleic acids) can be designed to detect a wide range of diseases - from emerging infectious diseases (e.g. Zika and Ebola) and high-prevalence infections (e.g. […]
DNA and RNA are naturally polarized molecules. Scientists believe that these molecules have an in-built polarity that can be reoriented or reversed fully or in part under an electric field. In a new study scientists show that all the DNA and RNA building blocks, or nucleobases, exhibit a non-zero polarization in the presence of polar […]
Researchers constructed integrated gene logic-chips called 'gene nanochips.' These self-contained nanochips can switch genes on or off according to the environment, where photo-reprogramming of the logic operation by UV irradiation is possible. Moreover, the researchers completed proof-of-concept experiments using artificial cells that produced the diagnostics and reactants (the desired RNA and protein) in a confined […]
Two international teams of security researchers have uncovered Foreshadow, a new variant of the hardware vulnerability Meltdown announced earlier in the year, that can be exploited to bypass Intel processors' secure regions to access memory and data.
