Heady Mathematics: Describing Popping Bubbles in a Foam

Heady Mathematics: Describing Popping Bubbles in a Foam

Bubble baths and soapy dishwater, the refreshing head on a beer and the luscious froth on a cappuccino. All are foams, beautiful yet ephemeral as the bubbles pop one by one.   Two University of California, Berkeley, researchers have now described mathematically the successive stages in the complex evolution and disappearance of foamy bubbles, a [...]

An Electronic Nose Can Tell Pears and Apples Apart

An Electronic Nose Can Tell Pears and Apples Apart

Swedish and Spanish engineers have created a system of sensors that detects fruit odours more effectively than the human sense of smell. For now, the device can distinguish between the odorous compounds emitted by pears and apples.   Researchers from the Polytechnic University of Valencia (UPV, Spain) and the University of Gävle (Sweden) have created [...]

Monkey Math: Baboons Show Brain’s Ability to Understand Numbers

Monkey Math: Baboons Show Brain’s Ability to Understand Numbers

Opposing thumbs, expressive faces, complex social systems: it’s hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait — the ability to understand numbers — also is shared by humans and their primate cousins.   “The [...]

Printable Functional ‘Bionic’ Ear Melds Electronics and Biology

Printable Functional ‘Bionic’ Ear Melds Electronics and Biology

Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can “hear” radio frequencies far beyond the range of normal human capability.   The researchers’ primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3D printing of cells and nanoparticles followed by [...]
