Researcher finds way to get audio from still images and silent videos
Posted by Genevieve Klien in categories: media & arts, robotics/AI
With video calls becoming more common in the age of remote and hybrid workplaces, “mute yourself” and “I think you’re muted” have become part of our everyday vocabularies. But it turns out muting yourself might not be as safe as you think.
Kevin Fu, a professor of electrical and computer engineering and computer science at Northeastern University, has figured out a way to get audio from pictures and even muted videos. Using Side Eye, a machine learning assisted tool that Fu and his research team created, Fu can determine the gender of someone speaking in the room where a photo was taken—and even the exact words they spoke.
“Imagine someone is doing a TikTok video and they mute it and dub music,” Fu says. “Have you ever been curious about what they’re really saying? Was it ‘Watermelon watermelon’ or ‘Here’s my password?’ Was somebody speaking behind them? You can actually pick up what is being spoken off camera.”

Scientists develop nanomaterials using a bottom-up approach
Posted by Paul Battista in categories: nanotechnology, particle physics
Scientists from the Friedrich Schiller University Jena and the Friedrich Alexander University Erlangen-Nuremberg, both Germany, have successfully developed nanomaterials using a so-called bottom-up approach. As reported in the journal ACS Nano, they exploit the fact that crystals often grow in a specific direction during crystallization. These resulting nanostructures could be used in various technological applications.
“Our structures could be described as worm-like rods with decorations,” explains Prof. Felix Schacher. “Embedded in these rods are spherical nanoparticles; in our case, this was silica. However, instead of silica, conductive nanoparticles or semiconductors could also be used—or even mixtures, which can be selectively distributed in the nanocrystals using our method,” he adds. Accordingly, the range of possible applications in science and technology is broad, spanning from information processing to catalysis.
“The primary focus of this work was to understand the preparation method as such,” explains the chemist. To produce nanostructures, he elaborates, there are two different approaches: larger particles are ground down to nanometer size, or the structures are built up from smaller components.

ChatGPT can now see, hear, and speak
Posted by Shubham Ghosh Roy in categories: mathematics, robotics/AI
We are beginning to roll out new voice and image capabilities in ChatGPT. They offer a new, more intuitive type of interface by allowing you to have a voice conversation or show ChatGPT what you’re talking about.
Voice and image give you more ways to use ChatGPT in your life. Snap a picture of a landmark while traveling and have a live conversation about what’s interesting about it. When you’re home, snap pictures of your fridge and pantry to figure out what’s for dinner (and ask follow up questions for a step by step recipe). After dinner, help your child with a math problem by taking a photo, circling the problem set, and having it share hints with both of you.
We’re rolling out voice and images in ChatGPT to Plus and Enterprise users over the next two weeks. Voice is coming on iOS and Android (opt-in in your settings) and images will be available on all platforms.

New vaccine technology could protect against future viruses and variants
Posted by Shubham Ghosh Roy in categories: biotech/medical, futurism
Studies of a “future-proof” vaccine candidate have shown that just one antigen can be modified to provide a broadly protective immune response in animals. The studies suggest that a single vaccine with combinations of these antigens—a substance that causes the immune system to produce antibodies against it—could protect against an even greater range of current and future coronaviruses.
The vaccine antigen technology, developed by the University of Cambridge and spin-out DIOSynVax in early 2020, provided protection against all known variants of SARS-CoV-2—the virus that causes COVID-19—as well as other major coronaviruses, including those that caused the first SARS epidemic in 2002.
The studies in mice, rabbits and guinea pigs—an important step before beginning human clinical trials, currently underway in Southampton and Cambridge—found that the vaccine candidate provided a strong immune response against a range of coronaviruses by targeting the parts of the virus that are required for replication. The vaccine candidate is based on a single digitally designed and immune optimized antigen.
