Nick was born outside of Melbourne, Australia, with a general curiosity that has drawn him to some distant (and very cold) places. Somewhere between enduring a winter in the Canadian Rockies and trekking through Chilean Patagonia, he graduated from university and pursued a career in journalism. Having worked for publications such as The Santiago Times and The Conversation, he now writes for Gizmag from Melbourne, excited by tech and all forms of innovation, the city's bizarre weather and curried egg sandwiches.

Nanorobots wade through blood to deliver drugs

By - June 17, 2015 1 Picture

Nanorobots hold great potential in the field of medicine. This is largely due to the possibility of highly-targeted delivery of medical payloads, an outcome that could lessen side effects and negate the need for invasive procedures. But how these microscopic particles can best navigate the body's fluids is a huge area of focus for scientists. Researchers are now reporting a new technique whereby nanorobots are made to swim swiftly through the fluids like blood to reach their destination.

EasyPal golf cart folds up with a push of a button

Unless you carry your clubs around yourself, a round of golf is often bookended with a clumsy assemblage and dismantling of a buggy's wheels, handles and axles. But for California-based GolferPal, this isn't the most ideal way to warm up or warm down – so the company has created a motorized golf buggy that does the work for you.

Miniature car runs only on the power of evaporating water

By - June 17, 2015 5 Pictures

Researchers have discovered an unlikely source of renewable energy, the naturally-occurring cycle that is water evaporation. Scientists at New York's Columbia University replicated this process in the laboratory and harnessed its energy to power tiny machines, one of which was a moving, miniature car. The team says the technology could potentially to be scaled up to one day draw power from huge resting bodies of water such as bays and reservoirs.

Micro Drone 3.0 shoots HD video stabilized by a mini-robotic gimbal

By - June 16, 2015 18 Pictures

Small, palm-sized quadcopters have a certain appeal within the increasingly cramped drone market. They're portable, low-risk and are generally an inexpensive way for rookie pilots to learn the ropes. But these pint-sized robots have their shortcomings. In developing its new Micro Drone 3.0, UK company Extreme Fliers has set out to work features typically found in high-end drones into a smaller package, namely HD video stabilized by a tiny gimbal and compatibility with Google cardboard VR for first-person view flying.

Avocado-derived molecule attacks leukemia at its roots

By - June 15, 2015 2 Pictures

Brimming with nutrients, antiooxidants and healthy fats, avocado – otherwise known as nature's butter – carries a multitude of health benefits inside its coarse, leathery skin. But new research is now pointing to what could be its most valuable secret yet. A Canadian scientist has discovered a lipid in avocado that could prove key to battling leukemia by attacking the deadly disease at its core, namely the highly resilient stem cells that drive the disease and make treating it such a difficult task.

Time-lapse captures the death of white blood cells for the first time

By - June 15, 2015 1 Picture

With a pivotal role in fending off infections and disease, white blood cells are the engine room of the body's immune system. But little was known about what happens exactly when these cells reach the end of their life cycles. Scientists have now captured the death of white blood cells on camera for the first time, showing that they eject much of their contents while decomposing. One reason for this could be to warn neighboring cells of dangerous pathogens in the area. The researchers say learning more about their expiration could help bring about improved health treatments in the future.

Video: The fast and furious world of underground drone racing

Chad Nowak describes himself as an aviation nutter. For 25 years he's been flying remote controlled aircraft and full-sized sail planes, fuelled by a fascination for anything that glides through the air. But this interest went up a notch when he came across a Youtube video of an emerging sport known as FPV (first person view) drone racing. Fast forward 12 months and his home in Queensland, Australia, is covered in half-built quadcopters and loose parts. Last weekend, Nowak flew to Melbourne to take on like-minded racers in an abandoned warehouse on the outskirts of the city.

Smart windows can be tuned for privacy, while still letting the light shine through

By - June 10, 2015 9 Pictures

The glass panels that let light into our homes and offices have been seen as huge windows of opportunity for engineers in recent times. If the amount of light pouring through can be managed throughout the day, it could lessen reliance on energy-sapping air conditioner units, for instance. This has led to a number of examples of smart facades that keep interior spaces from overheating, and some that even harvest energy for lights and ventilation. But a new tunable window-tinting technology is claimed to do things the smart glass before it cannot, by allowing users control over brightness, color temperature and opacity.

HGST's helium-filled HDD offers a world-first 10 TB of storage

By - June 9, 2015 3 Pictures

We first caught wind of HGST's high capacity hard drives in 2012, when the company claimed it could boost storage capacities by 40 percent by replacing regular old air inside the drive enclosure with helium. The Western Digital subsidiary stayed the course, producing a helium-based 6 TB HDD in 2013 and 8 TB model in 2014, and has now continued the upward trend with the world's first 10 TB hard drive.
