Cambridge team breaks superconductor world record

A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china. The Cambridge researchers managed to ‘trap’ a magnetic field with a strength of 17.6 Tesla - roughly 100 times stronger than...

Urban Skyfarm concept would provide inner city farming space

Two problems caused by increasing overpopulation in cities are how to use space productively and how to feed everyone. A new concept design suggests a means of addressing both these issues. Aprilli Design Studio's Urban Skyfarm is a tree-like skyscraper that provides space for crop farming. Aprilli designed the Skyfarm with Seoul, South Korea, in mind, but it could be deployed in any major...

Researchers Regrow Human Corneas: First Known Tissue Grown from a Human Stem Cell

Boston researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule known as ABCB5 that acts as a marker for hard-to-find limbal stem cells. This work, a collaboration between the Massachusetts Eye and Ear/Schepens Eye Research Institute (Mass. Eye and Ear), Boston Children’s Hospital, Brigham and Women’s Hospital and the VA Boston...

A step closer to bio-printing transplantable tissues and organs

Researchers have made a giant leap towards the goal of 'bio-printing' transplantable tissues and organs for people affected by major diseases and trauma injuries, a new study reports. Scientists from the Universities of Sydney, Harvard, Stanford and MIT have bio-printed artificial vascular networks mimicking the body's circulatory system that are necessary for growing large complex...

'MacGyver' Robots Use Their Environment to Solve Problems

MacGyver could make a rocket-powered harpoon gun/zip line out of some moth balls, cleaning fluid, rope, pulley, and an old telescope. Robots can't do that. But hey, neither can you. What you can do is use objects in your environment to help you complete tasks that you wouldn't otherwise be able to do on your own, and robots are learning how to do the same thing. Yes, this means that soon...

100% Renewable Electricity Will Be Achieved In German State Soon

From Clean Technica website (Jake Richardson): Germany’s windiest area, Schleswig-Holstein, will probably achieve “100% renewable electricity” sometime this year. That is, its clean energy production will be able to supply all of its electricity consumption. Schleswig-Holstein has a goal to generate 300% of its electricity consumption with renewables eventually. This mostly...

Swarm of Tiny 'Minibuilder' Robots Can 3D Print Giant Buildings On-Site

Although the advent of 3D printing is blazing trails in the world of design, the requirement for 3D printers to be larger than the objects they produce presents a major constraint - particularly in architecture. However an innovative new project called Minibuilders is poised to push past that limitation and revolutionize the construction industry. Developed by researchers at the Institute for...

3D-printed composite is lighter than wood and stiffer than concrete

In wind farms across North America and Europe, sleek turbines equipped with state-of-the-art technology convert wind energy into electric power. But tucked inside the blades of these feats of modern engineering is a decidedly low-tech core material: balsa wood. Like other manufactured products that use sandwich panel construction to achieve a combination of light weight and strength, turbine...

USC Scientists Create New Battery That’s Cheap, Clean, Rechargeable… and Organic

Scientists at USC have developed a water-based organic battery that is long lasting, built from cheap, eco-friendly components. The new battery – which uses no metals or toxic materials – is intended for use in power plants, where it can make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed. “The batteries last for...

New Device Allows Brain To Bypass Spinal Cord, Move Paralyzed Limbs

For the first time ever, a paralyzed man can move his fingers and hand with his own thoughts thanks to an innovative partnership between The Ohio State University Wexner Medical Center and Battelle. Ian Burkhart, a 23-year-old quadriplegic from Dublin, Ohio, is the first patient to use Neurobridge, an electronic neural bypass for spinal cord injuries that reconnects the brain directly to...

NASA Aeronautics Makes Strides to Bring Back Supersonic Passenger Travel

The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA aeronautics researchers will present their work in Atlanta this week at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are...

New ultrastiff, ultralight material developed

What’s the difference between the Eiffel Tower and the Washington Monument? Both structures soar to impressive heights, and each was the world’s tallest building when completed. But the Washington Monument is a massive stone structure, while the Eiffel Tower achieves similar strength using a lattice of steel beams and struts that is mostly open air, gaining its strength from the...

Mobile Solar Filter System Removes Microorganisms and Pollutants

Hydraulic engineer Andrea Schäfer and photovoltaics expert Bryce Richards have developed a solar filtration system to produce high-quality drinking water from polluted brackish water and tested it successfully in Tanzania. The test results are currently being analyzed at the KIT. The filter effectively separates undesired substances, bacteria, and viruses. Fluoride concentration that often...
