How to print a building—the science behind 3-D printing in construction

Building sites are going to look a bit different, in the future. Credit: Shutterstock It’s often claimed that 3-D printing – known in the trade as “additive manufacturing” – will change the way we live. Most recently, a team from Eindhoven University of Technology announced plans to build the “world’s first” habitable 3-D printed houses. But it’s one thing to build small, prototype homes in a park – it’s quite another to successfully use additive manufacturing for large scale projects…

Entrepreneurs seek to quantify pressure applied during manual therapy

IUPUI entrepreneurs are developing prototypes of force-sensing instruments to be used during manual therapy. The patent-pending instruments are being commercialized by Health Smart Technologies.  Credit: Liz Kaye, IU Communications Physical and occupational therapists, athletic trainers, chiropractors, veterinarians, and other medical professionals could improve the outcomes of manual therapy to treat soft-tissue injuries by using patent-pending, handheld instruments being developed by IUPUI entrepreneurs. Health Smart Technologies Inc., a medical device startup, is developing a force-sensing instrument system called Quantifiable Soft Tissue…

Why being left-handed matters for mental health treatment — ScienceDaily

Treatment for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population, according to a radical new model of emotion in the brain. Since the 1970s, hundreds of studies have suggested that each hemisphere of the brain is home to a specific type of emotion. Emotions linked to approaching and engaging with the world — like happiness, pride and anger — lives in the left side of the brain, while emotions…

Transforming Agriculture Through The Use Of Robots

Gone are the days when agriculture was an activity of the farm-hands. This is becoming a business and investment that is exciting and one that has attracted professionals and people from all walks of life. Not only has it become a well-paying profession but also one that employs the use of the latest technologies. Among the technologies that have stood out is the automation technology with a keen focus on robots and robotics. Part of these trends and changes have…

New report highlights how drones can be used for good of society

Credit: University of Sheffield A new report demonstrating how drones can come to the rescue in natural disasters, help starving people in conflict and provide emergency medicine has been published today (7 June 2018) by one of the UK’s leading robotics experts. The report, unveiled by the Foundation for Responsible Robotics, which is led by Professor Noel Sharkey from the University of Sheffield, outlines five key areas in which drones can be used to benefit humanity. Aside from industrial…

LED stool to combat back pain

The LED stool encourages healthy sitting. On the MS Wissenschaft, visitors can even use it to play movement games. Credit: Fraunhofer IAO Sitting down for hours on end is hazardous to our health – whether it is in the office, at school, in the car or on the sofa. Backaches, obesity, diabetes and other conditions are the consequences of a lack of movement. It is important, therefore, to integrate dynamic sitting into our everyday lives. In a fun exhibition on…

New technology could revolutionize testing, tracking of brain performance

Advanced mobile technology to manage underground utilities

Credit: Aisyaqilumaranas, Shutterstock Utility companies from the UK alone create over 1.5 million street holes each year, often causing damage to third-party assets. Damage can be both expensive and dangerous, while also seriously impacting a company’s reputation. Outdated and inefficient systems account for a great part of faulty interventions that costs the British economy in the region of 5.5 billion euro annually. To address these issues, a consortium stemming from six European countries established the LARA initiative. The project developed…

Researchers develop reprocessable thermosets for sustainable 3-D printing

3D printing reprocessable thermosets (3DPRTs) make 3D printed structures reshapeable, repairable and recyclable. Credit: Kavin Kowsari 3-D printing of complex structures that contain submillimeter-sized features has eluded researchers for decades. Recent advancements in 3-D printing have brought about viable 3-D printing techniques such as digital light processing (DLP)-based systems that use ultra-violet (UV) light to transform initially-liquid polymer resins into free-standing solid structures in a precise, controlled manner. Among all 3-D printing materials, thermosetting photopolymers claim almost half of the…

Heat and sound wave interactions in solids could run engines, refrigerators — ScienceDaily

A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators — resulting in leak-free machines that can stay operating longer. Leaky systems have limited how engineers design thermoacoustic devices that rely on the interplay between temperature oscillations and sound waves. Researchers at Purdue and the University of Notre Dame have demonstrated for the first time that thermoacoustics could theoretically occur in solids as well as fluids, recently…
