This robot chef can taste salt with its arm

 admin  0 202 

Robots can see in wavelengths beyond human eyes. Robots can hear in wavelengths beyond human ears. Robots can even feel with tactility approaching human skin. But when it comes to tasting, robots are laggards. Taste is a sense that may seem basic to any human, including young children licking food from the floor, but not to robots. Tasting technology doesn’t even come close to the multifaceted sensitivity of the human tongue. For robot-builders and food scientists alike, improving that technology…

This is Impact, a new sustainability series from PopSci. Many products often come with expiration dates to indicate a predetermined shelf life, like food and medicine. Once the indicated date has passed, these products are generally deemed unfit for use or consumption—but does that mean people should toss them out the…

 admin  0 82 

No matter how carefully you peel back the two chocolate wafers of an Oreo, the creme filling will always stick to one side. It’s not possible to split the creme down the middle.  That’s according to new fluid dynamics research published in the journal Physics of Fluid. While the finding might not be a total shock to snack aficionados, it sheds light on the next generation of 3D printed manufacturing. Crystal Owens, the lead author on the study, and a…

How to enjoy fake meat in a way that actually helps the planet

 admin  0 110 

Real life is much more complicated than a simple good versus bad. And in a world in climate turmoil where nobody is ever sure what’s right and wrong for the environment, the cast of heroes and villains is hardly black and white.  Still, the narrative is irresistible. And for some people, it can be pretty easy to fall into, even with simple decisions like what kind of burger to order. For Ricardo San Martin, the co-founder of the alternative meats…

 Naomi  0 102 

You might not think of mushrooms as great cooks. But fungi, as it happens, could be a wonderful way to make flavors. By using fungal enzymes to transform other biological material, it’s possible to create some rather pleasant aromas. Scientists have found a way to generate a potent wild strawberry scent by allowing one particular fungus to work on the pulp, seeds, and skin of black currants, a type of berry commonly grown in Europe. They published their results on…
