A new solar-powered catalyst made of graphene and titanium dioxide nanoparticles can pluck pollutants out of the air, much more efficiently than others. The catalyst could be coated onto building or street surfaces to improve air quality in cities.

Scientists are looking into replacing dead and crumbling coral heads with plastic replicas, and some fish prefer them to the genuine article.

Like the horse of Troy, scientists have developed a way to sneak synthetic cells right into tumor tissue, where they then begin producing cancer-fighting proteins from the inside. The technique was tested in both cell cultures and in mice, and found to be an effective treatment in both cases.

​There are some paraplegic rats that are now able to walk again, or that are at least coming close to doing so, and it's thanks to human stem cells. The cells essentially helped bridge a gap that scientists had introduced in the animals' spinal cords.

In recent years we've seen devices such as headbands that are designed to treat migraines. One of the latest such gadgets – which is worn on the arm like a blood pressure cuff – was recently the subject of a promising study.​

Could a nano array that can identify the chemical signatures of diseases bring us closer to the day when doctors might be able to use a medical tricorder a la Star Trek to instantly diagnose a patient’s conditions?

E.coli bacteria are more commonly associated with deadly outbreaks but a student team from Israel shows how they can also be used to detect harmful substances.

How nanoparticles can best navigate the body's fluids to deliver medicine is a huge area of focus for scientists. Researchers are now reporting a new technique whereby nanorobots are made to swim swiftly through the bloodstream to reach their destination.

On most fish, their hard, overlapping scales provide protection against pokes and cuts. Because those scales are attached to a flexible skin, however, the fish are still able to easily twist their bodies. Scientists are now attempting to copy that structure, to develop flexible-yet-effective armor.

There's plenty of excitement surrounding the emergence of nanotechnology. But scientists from the Technion-Israel Institute of Technology are urging caution, with a new study suggesting that exposure to silicon-based nanoparticles may play a role in the development of cardiovascular disease.

In order for microscopic "nanobots" to get to their destinations, they'll need some form of propulsion. A team of Israeli and German scientists has responded by creating what they claim is the world's smallest propeller.

Scientists at the Technion-Israel Institute of Technology have devised a system that allows an underwater camera to look up through the surface from below, with a minimum of distortion. In some situations, it could be used to replace periscopes on submarines.
