3D Printed Robotic ‘Elephant Trunk’ is Guided by Machine Learning Taking their inspiration from nature, researchers have designed a low-cost robotic arm that mimics the strength and flexibility of an elephant’s trunk. Image Credit: Villiers Steyn/Shutterstock.com In terms of design, the elephant's trunk is one of evolution’s foremost triumphs. The appendage — an extension of the animal’s nose and its upper lip — is both strong and flexible with a level of dexterity that is unmatched, even by our own arms. In fact, containing an immense 40,000 muscles, an elephant’s tr...

Restoration attempts are underway, but are they enough to halt the death of these important living ecosystems? Coral reefs rank amongst the most diverse ecosystems on the face of planet Earth, playing host to thousands of different species of animals. These r...

A new injectable biosensor could provide an early warning system of COVID-19 infection, spotting the virus up to 48 hours before symptoms appear. Image Credit: Lightspring/Shutterstock.com With the roll-out of COVID-19 vaccines well underway in most developed countries, attention is now beginning to focus on other aspects of the fight against the virus that has significantly changed our lives. One of the most crucial aspects of the COVID-19 battle is the early detection of the virus. Because of how it can be transmitted before symptoms manifest, and because many people with the disease will r...

How 3D printed Graphene Aerogels can be used for Water Treatment This illustration depicts, at the left, a 3D printer printing the hexagonal-shaped graphene aerogel sheet. At the right, the aerogel (now black) filters dirty water. Credit: Environmental Science: Nano Access to clean drinking water is a major problem for as much as a third of the world's population. Now, a new combination of graphene, aerogels and 3D printing could provide a solution.  With an increasing global population, the need for clean, accessible drinking water is growing. Graphene has long been suggested as a material ...
