It can’t be easy, being a lifeguard at a pool full of children. The kids that catch your attention are going to be the ones who are splashing and yelling, whereas the ones that you really need to look for could be silently slipping below the surface, where they won’t be seen or heard. North Carolina-based emergency physician Graham Snyder decided that those potential drowning victims needed more attention drawn to their predicament, so he created the Seal system. Read More

PureMadi filters clean water and create jobs in the third world

By - February 11, 2013 7 Pictures
Silver is known for its antibacterial qualities, and has thus found its way into water filters created at institutions such as Stanford and McGill universities. Given that these filters are often used in developing nations, however, it would be nice if they could also contribute to the local economy – instead of being just one more thing that’s brought in from outside. Well, that’s just the idea behind the University of Virginia’s PureMadi filters and MadiDrops. Read More

Specially-coated cotton collects water from desert fog – and releases it as liquid

By - January 21, 2013 2 Pictures
In arid places where fog occurs overnight, some people utilize so-called “fog harvesters” to acquire fresh water. These are typically pieces of netting that collect fog droplets, which then roll down into a container below. Various researchers have tried to increase the efficiency of these harvesters, such as by making them from a combination of hydrophilic (water-absorbing) and hydrophobic (water-repelling) materials. Now, a team of scientists have done something a little different – they’ve created a cotton-based fog-harvesting material that switches between being entirely hydrophilic and entirely hydrophobic.
