Brazilian-Italian Antonio Pasolini graduated in journalism in Brazil before heading out to London for an MA in film and television studies. He fell in love with the city and spent 13 years there as a film reviewer before settling back in Brazil. Antonio's passion for green issues - and the outdoors - eventually got the best of him and since 2007 he's been writing about alternative energy, sustainability and new technology.
Nobody knows exactly how climate change will play out in the coming decades, but the Poles are already being affected as ice melts away. Man-made sites in the region are also under threat as ice vanishes and, because of this, a Canadian researcher is on a mission to visually record one place that could soon become just a memory.
Researchers in Singapore have created a sensor-enabled adult diaper that monitors wetness and transmits alerts to caregivers via SMS. The system is designed to reduce rashes and infections that can result from insufficient changes.
Portable test kits represent an advance in disease diagnosis, as their
ready availability increases chances of earlier detection and treatment.
This type of technology is constantly evolving, and sometimes
inspiration can come from surprising sources. Such is the case with
research carried out by a Swiss team, which has borrowed from the
mechanics behind the firefly's glow to develop a sensitive molecule
Polylactic acid (PLA) is a biodegradable bioplastic that is already used to produce a variety of everyday items, such as cups, trays, bowls and vegetable wrapping foil. Unfortunately, the current PLA production process is expensive and produces waste. Researchers at the KU Leuven Centre for Surface Chemistry and Catalysis in Belgium have now developed a new production technique that is cheaper and greener and makes PLA a more attractive alternative to petroleum-based plastics.
The world’s oceans are in peril due to a combination of pollution, overfishing and climate change. Recently, the Alfred-Wegener-Institut, a German center for polar and marine research, sent out a strong warning about fundamental changes that are occurring in those ecosystems. But awareness is growing and the fight to preserve the oceans has found an ally in Adidas, which has teamed with conservation group Parley for the Oceans to create footwear made with trash harvested from the ocean.
Our well-being and mood throughout the day is largely influenced by the light we are exposed to. Following this principle, a start-up called Saffron has developed the prototype of a LED light that can sync our internal clock to the natural shifting color spectrum of the sun. The light is called Silk by Saffron, and the designers claim it can improve our humor and sleep patterns by giving us get the right kind of light for the each time of the day.
Pet parents have a range of devices these days to keep their furry children fed and entertained consistently in their absence. Now a new addition to the remote pet care market adds images and sounds to the fun. The Petzi Treat Cam taps the power of internet-enabled devices not only to dispense food remotely, but also see, speak to and take pictures of their four-legged children when away from home.
Our mobile devices running out of power is a constant worry, although portable chargers can help alleviate some of that anxiety. CulCharge, a new charger/powerbank still in its concept stage, is intended as an easy-to-carry option as it is small enough to slot onto a keychain.
A Swiss joint venture has developed a hybrid-electric powertrain for road sweepers that's said to consume half the energy of diesel-hydraulic vehicles and reduce emissions by more than 60 percent. The modular system can also be adapted to cleaner fuel types such as hydrogen.
Peek, the smartphone eye test app designed to improve eyecare in remote areas, has been found to be as accurate as traditional methods. According to a study published last week, tests with the app carried out between December 2013 and March 2014 produced levels of accuracy that were on a par with paper-based charts and expensive illuminated vision boxes found in clinics.
