Empa researchers have succeeded in developing an environmentally friendly ink for 3D printing based on cellulose nanocrystals. This technology can be used to fabricate microstructures with outstanding mechanical properties, which have promising potential uses in implants and other biomedical applications. In order to produce 3D microstructured materials for composite applications, for instance, Empa researchers have

Luke Skywalker’s bionic hand made possible by ultrasound technology Luke Skywalker’s bionic hand is a step closer to reality for amputees in this galaxy. Researchers at the Georgia Institute of Technology have created an ultrasonic sensor that allows amputees to control each of their prosthetic fingers individually. It provides fine motor hand gestures that aren’t

Silicon-based invention is tiny, soft, wirelessly functional In the campy 1966 science fiction movie “Fantastic Voyage,” scientists miniaturize a submarine with themselves inside and travel through the body of a colleague to break up a potentially fatal blood clot. Micro-humans aside, imagine the inflammation that metal sub would cause. Ideally, injectable or implantable medical devices

Robotic pets that respond to human interaction can benefit the health and wellbeing of older people living in care homes, a study from the University of Exeter Medical School has found. Researchers found evidence that ‘robopets’ can provide comfort and pleasure and reduce agitation and loneliness. Funded by NIHR Collaboration for Leadership in Applied Health

Researchers at Oregon State University have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The technology could be integrated with existing WiFi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several

Image via Wikipedia This story is, literally, stone age meets digital age: University of Washington researchers are combining the ancient art of ceramics and the new technology of 3-D printing. Along the way, they are making 3-D printing dramatically cheaper. About five years ago, Mark Ganter, a UW mechanical engineering professor and longtime practitioner of

Can breakdown cleaning agent residuals and pesticides as well as pharmacological substances  Many harmful substances in waste water stubbornly resist being broken down by biological waste water treatment plants. Fraunhofer researchers have developed a photochemical reaction system in which water can be reliably treated at high flow rates by UV light without having to add

The technology “offers nearly miraculous potential.” When a current passes between two electrodes — one thinner than the other — it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. This phenomenon, called electrohydrodynamic thrust — or, more

Many organs arise from simple sheets and tubes of cells. During development, these sheets bend and deform into the more complex final shape of the organ. This can be seen, for example, in the hindgut of fruit flies (Drosophila), which is an organ equivalent to our intestines. The Drosophila embryonic hindgut first forms as a bilaterally symmetric
