TastyFloats is a "contactless food delivery system" that uses ultrasound to raise bits of food and droplets of drink to your mouth without any utensils at all. While this method to levitate small objects is well known, what's fascinating is that a small scientific study shows that the levitated food apparently tastes better. Researchers from the University of Sussex describe TastyFloats and their sensory experiment in a scientific paper they'll present at this month's ACM Interactive Surfaces and Spaces conference. From IEEE Spectrum:
The researchers experimented with three of the five basic tastes: sweet (a positive taste), bitter (a negative taste), and umami, which is a savory taste that can also enhance other flavors. The researchers asked a group of volunteers to test TastyFloats with the three basic tastes, delivered in three different volumes (5 microliters, 10µL, and 20µL), with tongue delivery via pipette as a non-levitating control. Participants were asked to identify each droplet, and then rated each on intensity, pleasantness, and satisfaction.
The most significant difference between levitated tastes and tastes delivered via pipette was in intensity: sweet tastes were more intense and recognizable, while bitter tastes were harder to distinguish. The researchers suggest that this might make TastyFloats more suitable for dessert delivery, although it could also be used to make bitter but healthy foods (like broccoli) more palatable to people who wouldn't otherwise enjoy them.
One of the major contributors to greenhouse gases is the methane that cows belch up as they break down cellulose, but five years ago, research from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) found that adding small amounts of a pink seaweed called Asparagopsis to cows' diets eliminated the gut microbes responsible for methane […]
The City of Santa Monica is looking to displace a year old homeless feeding program because it is too successful. ABC7: Steve Petramale has been feeding at least 100 homeless people every week at Reed Park for more than a year. Santa Monica officials told Petramale the park is not a good location for his […]
Seamus Blackley, "father of the Xbox," worked with Egyptologist Serena Love and microbiologist Richard Bowman to extract yeast from 4,500-year-old Egyptian bread-making and beer-making potter held in the collection of Harvard's Peabody Museum; though nearly all of the samples are being cultured for analysis and addition to a microorganism library, Blackley cultured one sample to […]
Are we done with capsule coffee makers yet? Sure, they’re easy. But they are not so easy on the environment, and it’s debatable whether they actually make a better cup. Luckily, there’s never been a better time to switch back to the good old reliable drip method – especially when drip coffeemakers have quietly been […]
If there’s one thing that stayed consistent through the last decade or so of tech industry turmoil, it’s the love affair between techies and Linux. There’s just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up. Apparently not content with that level […]
Accidents happen. And when they do, you’re going to want a dash cam for a second pair of eyes. At the minimum, a decent dash cam can save you vast sums of time and money in case of an accident. But a really good dash cam can do a whole lot more. Here are six […]
