Manipulated videos, audio and images have been around for years, but the rise of artificial intelligence and advanced editing software have made them much, much harder to spot. It's a dangerous new world, where our very sense of reality can be thrown into doubt.

Researchers at Purdue University have begun a study they say will help determine if smartwatch data could be used to reliably and accurately detect symptoms of COVID-19 early. The university says the data could indicate that a potentially asymptomatic user should get tested for COVID-19.

From virtual assistants like Siri to self-driving cars and computer-aided medical diagnoses, artificial intelligence (AI) is affecting our lives with unprecedented speed. Slowly but steadily, scientists in a broad range of fields have started to embrace AI in their research, hoping to significantly reduce the time needed to achieve new discoveries. This trend has become more obvious in the physical sciences, and in the field of materials science in particular, which is focused on the discovery and production of new, advanced materials imbued with desirable properties or functions. Think: screens of foldable smartphones; batteries that power electric cars; or materials that bend light around them, rendering them invisible.

The National Science Foundation has announced awards totaling $104 million to create four new Engineering Research Centers (ERCs). The new centers, each with several leading American research universities collaborating as partners, will receive $26 million apiece for an initial five-year period.

Purdue University researchers are developing technology to reduce diagnosis time for bovine respiratory disease. The work, led by agricultural and biological engineering professor Mohit Verma, is being funded by a $1 million grant from the USDA’s National Institute of Food and Agriculture Inter-Disciplinary Engagement in Animal Systems grant.

Many smart phone users resort to deleting apps when their phone storage space is full. Purdue University researchers have come up with an innovative system that enhances faster application downloads while using less storage space. Purdue University Professor of Electrical and Computer Engineering joins us with details on how AppStreamer works.

Chronic wounds affect over 6.5 million Americans and are notoriously difficult to treat. Suboptimal oxygenation of the wound bed is one of the most critical and treatable wound management factors, but existing oxygenation systems do not enable concurrent measurement and delivery of oxygen in a convenient wearable platform. Thus, we developed a low-cost alternative for continuous O2 delivery and sensing comprising of an inexpensive, paper-based, biocompatible, flexible platform for locally generating and measuring oxygen in a wound region.

When probing the subtle effects of quantum mechanics, all the parameters in the system and its measurements need to be finely tuned to observe the result you are hoping for. So what happens when you gear everything towards detecting what you least expect? Researchers at MIT and Purdue University in the U.S. took just this approach and found they could amplify quantum signals by a factor of 30 while conditionally changing the relative phase of a photon from π/80 to π/2. The results could provide the missing link that nudges a number of quantum network technologies closer to practical use.

The way we consume multimedia content has changed over time, and so has the technology that delivers it. What began as downloading evolved into streaming, with remote copies of audio or video files transmitted over the Internet in real time—eliminating the need for a local copy stored on a device.

Santo Purnama (ECE'95), co-founder of Singapore-based biotech startup Sensing Self, has developed a rapid self-test kit for COVID-19, for people who want to test themselves at the comfort of their home
