Rapid, accessible and highly accurate detection of addictive substances such as opiates and cocaine is vital to reducing the adverse personal and societal impacts of addiction, something current drug detection systems can take too long to provide. However, on-site, real-time monitoring of abused drugs in a patient's system could alert [...]

A novel multidimensional characterization approach that combines several characterization techniques, allowing to get materials properties of the heterostructure with (almost) nanometer resolution. The method combines several microscopy tools into a multidimensional imaging tool that allows the inspection of materials' optical properties at a resolution much higher than with regular [...]

Sinuous stellar jets meander lazily across a field of stars in new images. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations were made using the Gemini South telescope's adaptive [...]

The energy systems that power our lives also produce wasted heat -- like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously [...]

Atom-level simulations reveal the reason iron rusts in supposedly 'inert' supercritical carbon dioxide fluid. Trace amounts of water can cause a reaction at the interface between iron and the fluid, prompting the formation of corrosive chemicals. [...]

A research team has developed an optical computing system for AI and machine learning that not only mitigates the noise inherent to optical computing but actually uses some of it as input to help enhance the creative output of the artificial neural network within the system. [...]

Researchers have developed a new control approach that enables a legged robot, called ANYmal, to move quickly and robustly over difficult terrain. Thanks to machine learning, the robot can combine its visual perception of the environment with its sense of touch for the first time. [...]

Industry and private consumers alike depend on oil and gas pipelines that stretch thousands of kilometers underwater. It is not uncommon for these pipelines to become clogged with deposits. Until now, there have been few means of identifying the formation of plugs in-situ and non-destructively. Measurements now show that neutrons [...]

There are few environments as unforgiving as the ocean. Its unpredictable weather patterns and limitations in terms of communications have left large swaths of the ocean unexplored and shrouded in mystery. “The ocean is a fascinating environment with a number of current challenges like microplastics, algae blooms, coral bleaching, and rising [...]

Researchers used all-inorganic nonhazardous germanium halides as ideal halide sources to synthesize both Pb-free and Pb-based PNCs with high optoelectronic quality. [...]

While mammograms are currently the gold standard in breast cancer screening, swirls of controversy exist regarding when and how often they should be administered. On the one hand, advocates argue for the ability to save lives: Women aged 60-69 who receive mammograms, for example, have a 33 percent lower risk [...]

For the first time, scientists believe they have detected a merger of two black holes with eccentric orbits. This can help explain how some of the black hole mergers detected are much heavier than previously thought possible. [...]

If you can recognize a dog by sight, then you can probably recognize a dog when it is described to you in words. Not so for today’s artificial intelligence. Deep neural networks have become very good at identifying objects in photos and conversing in natural language, but not at the [...]

A novel deep convolutional neural network AI algorithm can detect COVID-19 within minutes with 98% accuracy. [...]

Artificial intelligence helps build physical infrastructure like modular housing, skyscrapers, and factory floors. “…many problems that we wrestle with in all forms of engineering and design are very, very complex problems…those problems are beginning to reach the limits of human capacity,” says Mike Haley, the vice president of research at [...]

In theory, Web3 is all about decentralization. In practice, it can be very centralized. API3 is a bold effort to achieve decentralization in connecting Web3 applications to the outside world. [...]

In a busy hospital, a radiologist is using an artificial intelligence system to help her diagnose medical conditions based on patients’ X-ray images. Using the AI system can help her make faster diagnoses, but how does she know when to trust the AI’s predictions? She doesn’t. Instead, she may rely on [...]

Researchers have successfully demonstrated proof-of-concept of using their multimodal transistor (MMT) in artificial neural networks, which mimic the human brain. This is an important step towards using thin-film transistors as artificial intelligence hardware and moves edge computing forward, with the prospect of reducing power needs and improving efficiency, rather than [...]

Imagine a team of physicians using a neural network to detect cancer in mammogram images. Even if this machine-learning model seems to be performing well, it might be focusing on image features that are accidentally correlated with tumors, like a watermark or timestamp, rather than actual signs of tumors. To test [...]

A new artificial intelligence algorithm analyses MRI data to accurately predict the age of a brain. [...]

The National Bureau of Economic Research analyzed the side effects of remote work using data from GitHub. [...]

Warnings have emerged about the unreliability of the metrics used to detect whether an audio perturbation designed to fool AI models can be perceived by humans. Researchers show that the distortion metrics used to detect intentional perturbations in audio signals are not a reliable measure of human perception, and have [...]

It's not just about data prep. The acquisition of Trifacta is designed to accelerate Alteryx's cloud pivot. [...]

Qlik, one of the original self-service BI players, has submitted a draft registration with the SEC related to a proposed public offering. [...]

When Hongzhi Gao was young, he lived with his family in Gansu, a province located in the center of northern China by the Tengger Desert. Thinking back to his childhood, he recalls the constant, steady wind of dirt outside their house, and that during most months of the year it [...]
