Protein prevents your ice cream from melting quickly
In the future, you might not have to rush to eat your ice cream cone on a hot summer's day. Scottish researchers have discovered a naturally occurring protein that binds the air, fat and water in ice cream, which slows melting. The move would prevent your dessert from becoming a puddle, and spare companies from deep freezing their treats for as long as they do today. You could see higher-quality ice cream, too -- the protein promises a smoother texture without as many ice crystals or saturated fats.
Researchers wrangle microscopic particles with sonic lasso
When you think about it, scientists and cowboys have a lot in common. Both are frontiersmen of a sort, both wear clothes that make them easy to identify and now they both count lassos among their essential tools. Researchers at the University of Bristol and the University of Dundee have wrangled small particles and cells by using a sonic (or ultrasonic) vortex. The whirl of sound waves allowed the teams to catch, move and orient microscopic particles, all without actually contacting them physically, which makes the solution ideal for handling delicate material. Professor Bruce Drinkwater from Bristol even suggested it could one day be used to assemble human tissue (custom assembled livers, anyone?). The sonic lasso is quite a bit more complex and less portable than its rope-based cousin, involving a circular device with 16 sources of acoustic waves. If you're looking for more technical details you'll find a link to the recently published paper titled, Dexterous manipulation of microparticles using Bessel-function acoustic pressure fields at the source.
Dundee student designs Passive Play toy cube to stimulate parent interaction with autistic children
A University of Dundee scholar has been working on a wonderful tool that aims to evoke the emotional connection between children with autism and their parents. While we've seen novelties like the My Keepon in the past, any addition to the cause is always a pleasant one, and the Passive Play's no exception. The concept comes in the form of an interactive toy cube for the kid (pictured above), which pairs up with an iOS app and allows the parent to see any interaction the little one is having with the device. Passive Play's creator, Tom Kirkman, says his inspiration comes from "wanting to learn more about autism," and in case you happen to be in the UK, he'll be showing off the project at Dundee University later this month. For all those details, be sure to check out the PR after the break.
