Graphene is incredibly thin, flexible, strong and electrically conductive, but it’s tricky to manufacture on large scales. Now researchers at the University of Rochester have recruited bacteria to make the stuff, which is cheaper and faster than current methods and doesn’t require harsh chemicals.

It's not enough to just reduce our carbon dioxide emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at KIT have developed a simple way to turn the troublesome gas into a useful resource: by converting it into the “wonder” material graphene.

The wonderful potential of graphene has been well covered on our pages. One thing missing has been a cost-effective way to produce the wonder material, but a team of researchers now believe they may have discovered a key to this hiding in the bark of Australian eucalyptus trees.

There has been a lot said and written about the possibilities of graphene sheets, but material scientists at Northwestern University are casting their minds toward a malleable form of the material that can be kneaded and molded like Play-Doh.

Water filters get less effective as bacteria builds up on their surface. Now, researchers at Washington University in St. Louis have developed a new type of membrane that reduces such biofouling by actively killing bacteria with graphene – and in an interesting twist, it’s built by bacteria.

Practical quantum computers may be another step closer to reality, thanks again to graphene. The bits of information in quantum computers (qubits) can exist in two states at once, and now researchers have managed to record just how long that superposition state can last in a qubit made of graphene.

There are a variety of situations that may call for the implantation of electrodes in the brain, ranging from the treatment of neurological conditions to restoring the function of paralyzed limbs. A newly-developed hydrogel could someday replace such electrodes, allowing for better functionality.

Graphene has a great deal of potential applications, including its use in energy storage, building materials and medical devices. According to the National University of Singapore, however, most commercially-produced graphene is of a poor quality.

Could your home one day be powered by patches of mushrooms? Probably not, but scientists have nonetheless created a "bionic mushroom" that does indeed generate electricity – and it may pave the way for more practical bio-electric systems.

MIT engineers recently managed to create cell-sized robots that could collect data about their environment, but were a little tricky to manufacture. Now, the team has found a way to mass produce these synthetic cells (syncells) through controlled fracturing of graphene.
