Ordinary inkjet printers can be given a special cartridge containing DNA-based bio-ink tha...

Sensors that identify infectious disease and food contaminants may soon be printed on paper using ordinary office inkjet printers. Researchers at McMaster University have developed a prototype that could lead to a commercial product in the next few years which helps doctors and scientists in the field quickly detect certain types of cancer or bacterial and respiratory infections or monitor toxin levels in water.  Read More

Researchers at at Drexel University have developed a metallic nanocoating derived from a virus of the tobacco plant that could lead to more efficient steam production, improving the performance of steam turbines, air conditioning and electronics cooling systems.  Read More

In hot, dry areas of the world, collecting enough rainwater to grow crops can be difficult. Another potential source of water for collection, however, can be dew. Roots Up has designed a greenhouse to collect dew in Gondar, Ethiopia, as part of a scheme to help local farmers with low-tech solutions.  Read More

Mars as it may have looked 4.5 billion years ago (Image: European Southern Observatory)

In Edgar Rice Burroughs's Barsoom novels, Earthman John Carter's adventures took place on the dry beds of Mar's ancient oceans. Now NASA scientist's say that may not be so far fetched. Though they haven't found signs of any thoats, they have estimated that Mars may once have had enough water to form a vast ocean surrounding its north pole of which only plains remain.  Read More

There's a lot of water constantly moving through the municipal pipelines of most major cities. While the water itself is already destined for various uses, why not harness its flow to produce hydroelectric power? Well, that's exactly what Lucid Energy's LucidPipe Power System does, and Portland, Oregon has just become the latest city to adopt it.  Read More

Carlo Ratti Associati's Personal Cloud detects when individuals walk below it and sprays t...

One way of keeping people cool in hot climates is to spray a cool mist through which they can walk. Spraying mist continuously, however, can use a lot of water. A new installation called Personal Cloud reduces the amount of water used by detecting passersby and targeting mist at them only.  Read More

GE's new Laser MicroJet drilling holes in high-pressure turbine blades (Photo: GE Aviation...

Turbine blades for use in jet engines need to be made of a hard, unyielding exotic material made to exact specifications, which means the drilling of tiny cooling holes in the blades runs the risk of ruining them. To prevent this from happening, GE is combining the heat of the laser beam with the cooling of the water jet to drill holes without weakening the blades.  Read More

NASA's SMAP satellite blasts off from the Vandenburg Air Force Base, California (Image: NA...

On its third attempt, NASA has successfully launched its Soil Moisture Active Passive (SMAP) satellite atop a United Launch Alliance Delta 2 rocket. The orbiter is designed to take high resolution moisture maps on a global scale, mapping the entire planet in the space of only two to three days. The maps will grant us an improved ability to forecast droughts, floods, and even aid agricultural workers in crop planning and rotation.  Read More

The tower is rated as lasting up to 10 years and will require that locals are trained in o...

As water shortage is a serious issue in many parts of the world, a means of efficiently harnessing safe drinking water from thin air without the need of expensive infrastructure could be a real lifesaver. Italy's Architecture and Vision is developing an off-grid bamboo tower called Warka Water that promises just that: the firm says it could collect an annual average of up to 100 liters (26.4 US gallons) of water per day.  Read More

Discarded plastic items await recycling (Photo: Shutterstock)

A Mexican startup Ak Inovex has developed a new method of recycling plastic that does away with water and only consumes half the energy of previous systems. At the same time, it produces plastic pellets of equal or better quality,  resulting in an environmentally friendlier process that also promises to be significantly cheaper.  Read More
