Scientists at MIT are developing hybrid materials that are a cross between living bacterial cells and non-living components such as gold nanoparticles or quantum dots. The resulting "living materials" are able to respond to their environment like regular living cells, while also doing things like conducting electricity or emitting light.  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

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

The gel-tags use nanotechnology to show when a product has gone off

We're all familiar with the sell-by dates stamped on groceries. They're supposed to protect us, but in practice, they can be a bit of a coin toss. Now a research team led by Chao Zhang of Peking University in Beijing, China has come up with a color-coded smart tag that uses nanotechnology to tell when the food or drugs in a package are in danger of spoiling.  Read More

Smartphones with simple lens attachments might soon be able to analyze fluid samples (Phot...

We've recently seen a number of projects aimed at creating Star Trek-like medical tricorders, that take the form of stand-alone electronic devices built specifically for the purpose. Now, however, scientists at the University of Houston are taking an approach that's currently popular in many other areas of product design – they've asked, "Why build a whole new device, if a smartphone can provide the electronics?". The result is a proposed phone lens attachment, that could be used to diagnose diseases in real time.  Read More

In this false-color image, E. coli bacteria (green dots) can be seen trapped around pit me...

In many parts of the world, the presence of harmful bacteria makes it vitally important that water from lakes or rivers be thoroughly filtered before being consumed. While materials such as silver nanoparticles and titanium dioxide will do the job, people in developing nations or rural settings typically need something a lot cheaper and easier to manufacture. As it turns out, wood from pine trees works great.  Read More

Patterns created by bacteria swimming through the living liquid crystal

With any medical condition, the earlier it's detected, the better the chances are of successfully treating it. When assessing biological samples from a patient, however, it's often quite difficult to see the indicators of a disease when it's still in its early stages. That could be about to change, thanks to the development of a solution known as "living liquid crystal."  Read More

Designer Peter Trimble has built a machine that creates biostone furniture

With energy production and raw material shortages becoming increasingly pertinent issues around the world, designer Peter Trimble has demonstrated a radical method of manufacture that addresses both issues. Dupe is a portable machine that uses a mixture of sand, bacteria and urine to create a material called biostone. The machine is a proof-of-concept design only and is currently set up to create a small stool, but the method can be adapted to create just about anything.  Read More

A new approach targets bad bacterai, such as Salmonella (pictured), while leaving good bac...

The increasing prevalence of bacteria resistant to antibiotic drugs is largely blamed on the over prescription and use of such drugs in humans and animals, leading to the evolution of so-called "superbugs." A new antibiotic "smart bomb" that can target specific strains of bacteria could provide the next-generation antibiotic drugs needed to stave off the threat of antibiotic-resistant bacteria.  Read More

The humidity-driven flexing of a spore-covered piece of latex rubber (right) drives the mo...

Ozgur Sahin believes that water evaporation is the largest power source in nature. In an effort to demonstrate the potential of this untapped resource, Sahin and his fellow researchers have created prototype electrical generators with rubber sheets that move in response to changes in humidity thanks to a coating of bacterial spores.  Read More
