Low-cost water purifiers use chip packets to kill off dangerous bacteria

By - September 16, 2014 3 Pictures
Armed with plywood, a glass tube and some empty chip packets, mechanical engineering students from the University of Adelaide have developed a low-cost water purification system capable of killing off harmful bacteria. The solution is designed for remote communities in Papua New Guinea (PNG), an area where water is particularly susceptible to pathogen infestation. Read More

NASA probe will reveal 3D architecture of forests from space

By - September 14, 2014 1 Picture
NASA is developing a laser-based instrument for deployment on the International Space Station that will probe the depths of Earth's forests from space in a bid to reveal more about their role in the planet's carbon cycle. After its completion in 2018, this Global Ecosystem Dynamics Investigation (GEDI) lidar will join the likes of the Soil Moisture Active Passive satellite in studying Earth's vegetation on a global scale.

Withings Home acts as a security camera, environmental monitor and home diary

By - September 9, 2014 7 Pictures
Home camera systems from baby monitors to full-blown security systems are nothing new, but living with them can be about as comfortable as living in the novel 1984. Making its debut at this year’s IFA electronics show in Berlin, the Withings Home video and environmental monitoring device tries to dispel that vibe in a user-friendly package that blends into modern home decor.

AREND Project aims to ward off poachers with unmanned aerial vehicles

By - September 2, 2014 2 Pictures
Like many a technology before it, the aerial drone is finding applications far beyond military circles, from burrito delivery to surveying broken bridges. One emerging area with huge potential is wildlife conservation, with drones delivering the ability to patrol and detect illegal poachers from the air. AREND (Aircraft for Rhino and Environmental Defense) is an international team of students currently developing an unmanned aerial system with the ultimate objective of combating poaching in Africa's national parks.

In pictures: Singapore's surreal Supertree Grove and Cloud Forest

By - August 29, 2014 20 Pictures
There are places on this Earth where you simply stand, slack-jawed, and pinch yourself to make sure you're not dreaming – and Singapore's Gardens by the Bay is as surreal a place as I've ever been. This billion-dollar techno-garden theme park is absolutely stunning right through, but the two stand-out highlights are its signature Supertree Grove – a collection of giant cyborg trees – and the Cloud Forest – a gigantic bio-dome that recreates the environment and climate of a mountaintop forest at sea level. As a bonus, there's also the world's tallest indoor waterfall. Read More

Autonomous mini helicopters hunt down invasive weeds from the air

By - August 26, 2014 10 Pictures
The sheer density of the rainforests in Australia's far-north creates a slight problem for local conservationists. With incursions by invasive plants posing a threat to the native flora, inaccessibility for people makes it a difficult and time-consuming task to monitor the region. Now researchers from the CSIRO have developed two mini helicopters capable of hunting down the dangerous weeds from the air, significantly reducing the resources needed to preserve local plant life.

Whooshh Innovations' "fish gun" shoots salmon over obstacles small and tall

By - August 21, 2014 2 Pictures
If you live in an area where salmon spawn, then summer treats you to a free nature drama as the fish battle against currents, fight through rapids, struggle up tiny streams, and leap up waterfalls to return to the calm pools where they were born. Unfortunately, however intrepid the odd salmon is, they weren't built to take on a 300-ft tall hydroelectric dam. That's why Whooshh Innovations has developed a system that sucks the fish up through a plastic tube and shoots them over obstacles low and tall like so many piscatorial projectiles. Read More

Cigarette butts transformed into high-performance supercapacitor component

By - August 6, 2014 1 Picture
Billions of cigarette butts are discarded around the world each year and, even when disposed of properly, pose a threat to the environment by leaching arsenic, lead and other nasty chemicals into land and waterways. New research shows these butts could be set for a new lease on life, with a team of Korean scientists demonstrating that used cigarette filters could actually double as a highly-effective energy storage material.

BioSkin defies urban heat island effect to help keep buildings cool

By - July 24, 2014 9 Pictures
The urban heat island effect, whereby the high concentration of heat-retaining concrete and bitumen causes metropolitan centers to be significantly warmer than the rural areas surrounding them, is a common problem around the world. The phenomenon is particularly prevalent in Tokyo, Japan, but among the sea of towering structures stands one beacon of hope. The BioSkin that coats the NBF Osaki Building integrates evaporative cooling to keep its surface temperature down and could inspire new solutions to rising city temperatures across the globe.
