DrinkPure water filter shows promise for worldwide use

It's no secret that hundreds of millions of people around the world have little or no access to drinkable water. While a number of projects are aimed at getting filtration systems to those people, many of those systems require electricity, contain costly materials such as silver, or treat the water at a slow rate. The low-cost DrinkPure filter, by contrast, is simply screwed onto the top of an existing bottle, and can purify approximately one liter (34 fl oz) of water per minute. Read More

Research suggests Earth microbes could survive on Mars

Since the first Mariner probes reached the Red Planet in the 1960s, it’s become clear just how very alien Mars is and how hard it is to find parallel examples of possible Martian life on Earth. However, it’s not impossible. Rebecca Mickol, a doctoral student in space and planetary sciences at the University of Arkansas, has discovered that two species of methane-producing bacteria can live in the harsh conditions on Mars, and may aid in the search for life there.Read More

Cicada wings inspire new approach to antibacterial surfaces

Imagine if you took a water balloon and placed it on a bed of widely-spaced blunt nails. While the nails wouldn’t be pointy enough to pierce the balloon’s rubber skin, eventually the weight of the water would cause the rubber suspended between the nails to rupture. Well, it turns out that the clanger cicada uses the same principle to kill bacteria that settle on its wings. That finding could result in a new generation of antibacterial materials. Read More

PureMadi filters clean water and create jobs in the third world

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

Purrfect Air system uses a plant to eliminate kitty litter odors

Indoor green walls, for those who don’t know, are essentially flat vertical surfaces that are completely covered in plants. Not only do they look nice, but they also help remove toxins from the air. Now, gardening entrepreneur Mark Prescott has taken that same idea and applied it to a cat litter box deodorizer, known as the Purrfect Air Litter Box System. Read More
