Jeremy Nussbaumer with the DrinkPure filter

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

Methanogens prepared to be exposed to Martian conditions

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

A team of researchers from MIT may have found new evidence to shed light on the cause of the most devastating mass extinction in the history of our planet. The event, estimated to have taken place around 252 million years ago, was responsible for the extinction of roughly 90 percent of all life on Earth.  Read More

Samples of the coating, which contains dyes that make bacteria die

Hospital-acquired infections are a major health threat, and have prompted the development of preventative measures incorporating things like blue light and selenium nanoparticles. One of the latest such developments is a light-activated antimicrobial surface coating made from silicone, dye and gold. For some reason, it also works in the absence of light.  Read More

The MicrobeScope is a mini microscope designed for use with the iPhone

We've seen devices that let you attach your smartphone to a microscope, but they require you to have access to a microscope in the first place. What if you don't? Well, that's where the MicrobeScope comes in. It's a portable 800x microscope that works with newer iPhones – or just with the naked eye.  Read More

Researchers have finally discovered the key to dark chocolate's health benefits (Photo: Sh...

It has long been known that eating chocolate, particularly dark chocolate, has numerous health benefits. Although various studies have backed this up, the exact reason as to why this is so has remained a mystery. Now researchers from Louisiana State University have provided the answer – gut microbes.  Read More

Antimicrobial Corning Gorilla Glass is claimed to kill up to 99.9 percent of bacterial pop...

Last July, Corning announced that germ-killing glass for mobile device screens could be less than two years away. Well, things are apparently progressing quickly. Yesterday, the company unveiled its Antimicrobial Corning Gorilla Glass – although you can't buy a phone that features it quite yet.  Read More

A bacterium, after being 'deflated' by a cicada wing's array of blunt spikes

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 project leaders James Smith and Dr. Rebecca Dillingham

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

A diagram of the Purrfect Air Litter Box System

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
