Combining machine learning with multimodal electrochemical sensing can significantly improve the analytical performance of biosensors, according to new findings from a Penn State research team. These improvements may benefit noninvasive health monitoring, such as testing that involves saliva or sweat. The findings were published this month in Analytica Chimica Acta. The researchers developed a novel analytical platform that enabled them to selectively measure multiple biomolecules using a single sensor, saving space and reducing complexity as compared to the usual route of using multi-sensor systems. In particular, they showed that their sensor can simultaneously detect small quantities of uric acid and tyrosine--two important biomarkers associated with kidney and cardiovascular diseases, diabetes, metabolic disorders, and neuropsychiatric and eating disorders--in sweat and saliva, making the developed method suitable for personalized health monitoring and intervention.

Deepfakes – or fake videos produced to look real through the use of artificial intelligence – pose a growing challenge. That's why an EPFL research group has been teaming up with the Swiss startup Quantum Integrity to develop a deepfake detection solution over the past two years. The team has been awarded an Innosuisse grant starting on 1 October, with deployment as early as next year. Barak Obama insulting Donald Trump, Trump accusing Obama of stealing, and Mark Zuckerberg making worrying claims about how Facebook uses personal data – fake videoslike these, which look disturbingly real as a result of artificial intelligence, have been spreading across social media over the past few years. Until recently there were still some tell-tale signs that could indicate videos were fabricated, like eyes that never blink.

Capital markets are kind of like poetry: The words imply many different things at once and the profitable industry behind it is dominated by a well-educated elite fluent in complicated words that make little sense in the world of what we can see, taste and touch. Unlike poetry, it's never sexy to rattle off capital market jargon on a date while strumming guitar ballads. Investors usually pay experts to help them navigate the lucrative chaos, from the stock exchange to commercial real estate. But now emerging technologies like blockchain and artificial intelligence software tools are changing the game. Fintech is making capital markets more accessible and transparent than ever before.
