Revolutionary new wheelchair boasts hands-free backrest-based steering

Steering a wheelchair to the left or right can be a strenuous, inefficient process, in that you have to brake with one rear wheel while pushing harder on the other. A clever new chair addresses that problem in a brilliant fashion, by using a moveable b… Continue reading Revolutionary new wheelchair boasts hands-free backrest-based steering

Microscopic pirates attack with cellular cannons and grappling hooks

Microscopic battles rage around, on and in us at all times, and the microbial combatants use far more exciting weapons than we might realize. Scientists have now observed a bacterium that attacks like a pirate ship, ensnaring its prey with grappling ho… Continue reading Microscopic pirates attack with cellular cannons and grappling hooks

New material combines strength and stiffness with sound-damping properties

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs vibrations while staying stiff and thin.Continue Readin… Continue reading New material combines strength and stiffness with sound-damping properties

Multi-talented quadruped robot now climbs ladders faster than any other

The ANYmal quadruped robot not only walks on four legs, it can also roll on four wheels, stand up, throw boxes, and make its way up and down stairs. As if all that wasn’t enough, the thing can now also climb ladders.Continue ReadingCategory: Robotics, … Continue reading Multi-talented quadruped robot now climbs ladders faster than any other

Drone-dangled probe gathers DNA from treetops so we don’t have to

Gathering genetic material from treetops in tropical rainforests would be a near-impossible task to perform safely by hand. That’s why scientists have developed a system that allows a drone to do the job, without even touching the trees itself.Continue… Continue reading Drone-dangled probe gathers DNA from treetops so we don’t have to

Homes could soon be quickly built by clay-shooting “impact printers”

While clay is widely used to build basic structures such as huts, we typically don’t see it being utilized in large-scale construction projects. That could soon change, however, thanks to a recently developed process known as impact printing.Continue R… Continue reading Homes could soon be quickly built by clay-shooting “impact printers”

Remote surgery performed on a pig 9,000 km away using a game controller

Doctors have successfully operated on a pig – from 9,300 km (5,780 miles) away. Using a video game controller, surgeons in Switzerland successfully performed an endoscopy on a pig in Hong Kong, paving the way for remote procedures in humans in areas wh… Continue reading Remote surgery performed on a pig 9,000 km away using a game controller
