Sizzling Sound of Deep-Frying Reveals Complex Physics of Vapor Cavities

Experienced cooks can tell when cooking oil is at the right temperature by the sizzling sound produced by inserting moist chopsticks. Moistened chopsticks, water droplets in hot cooking oil reveal complicated bubble dynamics and sound characteristics. As its name implies, fluid mechanics is a branch of physics concerned with the mechanics of fluids (liquids, gases, … Read more

Integration and sound science are key for personalized supplements

If you ask Shawn Bushouse, president of emerging brands at Nestlé Health Science, the parent company behind Persona, consumer understanding of nutrition has become much more sophisticated in recent years. “They know there’s no such thing as one-size-fits-all supplements,” he says. “They need a diet tailored to their age, their diet, their lifestyle, their health … Read more

Direct sound printing is a potential game-changer in 3D printing, according to Concordia researchers – BIOENGINEER.ORG

Most 3D printing methods currently in use rely either on photo (light) – or thermo (heat) -activated reactions to achieve precise manipulation of polymers. The development of a new platform technology called direct sound printing (DSP), which uses soundwaves to produce new objects, may offer a third option. Most 3D printing methods currently in use … Read more

Coral Reefs Generate a Hidden Sound Underwater, And It Could Help Us to Save Them

We tend to associate healthy coral reefs with their visual splendor: the vibrant array of colors and shapes that populate these beautiful underwater ecosystems. But they can also be rather noisy places. If you’ve ever been snorkeling in a coral reef environment, you’ll know the distinctive clicking and popping sounds made by various marine creatures … Read more

This Study Might Make You More Mindful When You Talk to Your Pets

Dogs aren’t the only animals that can hear the emotion in our voices. According to new research, pigs and horses can also tell the difference between positive and negative expressions in human speech, and it could change how they respond to us. Previous studies have shown that domesticated horses can read emotions on human faces … Read more

These Eerie Wails Are a Real Sound Wave From a Supermassive Black Hole

We might not be able to hear sound in space, but that doesn’t mean there isn’t any. In 2003, astronomers detected something truly astonishing: acoustic waves propagating through the gas surrounding a supermassive black hole, 250 million light-years away. We wouldn’t be able to hear them at their current pitch. Emanating from the supermassive black … Read more
