3D-bioprinting replacement body parts require the use of bio-inks that are not only biocompatible but are also strong yet flexible at the same time. Currently used materials, however, have a hard time supporting themselves, which means that they have to be printed with supporting … [Read more...] about Sunflower pollen could provide tougher 3D-bioprinting ink

This device connects to your fingertips to produce energy while you sleep
Earlier this year, we wrote about a breakthrough study from the University of Tokyo, where scientists invented a sustainable smart-watch battery that uses nothing but the wearer’s sweat to generate electricity. Following in the footsteps of that innovation, engineers at the … [Read more...] about This device connects to your fingertips to produce energy while you sleep
Lobster-inspired hydrogel could help build artificial tendons
Earlier this year, we shared a story about how lobsters are inspiring scientists to develop stronger 3D-printed concrete. In a similar manner, scientists are now turning to the intricate architecture of the crustacean’s underbelly to develop a strong and stretchy hydrogel-based … [Read more...] about Lobster-inspired hydrogel could help build artificial tendons
‘Micro-tree’ harvester purifies water and extracts it out of thin air
Water scarcity is one of the most challenging problems humanity faces. Water is floating in the air all around us and in our oceans, but despite having so much water on Earth, only a tiny fraction of it is actually drinkable — while the rest of it is either too salty, … [Read more...] about ‘Micro-tree’ harvester purifies water and extracts it out of thin air
Solar-powered SmartFarm harnesses water from the air to irrigate plants
Wouldn’t it be great if we could harness the water vapor in the air to irrigate plants in areas with little precipitation? Well, that may happen sooner than you think thanks to a team of scientists from the National University of Singapore who have developed an experimental … [Read more...] about Solar-powered SmartFarm harnesses water from the air to irrigate plants
