MIT engineers have developed a nanoscale biological coating that can halt bleeding nearly instantaneously, an advance that could dramatically improve survival rates for soldiers injured in battle. The researchers, led by Paula Hammond and funded by MIT’s Institute of Soldier Nanotechnologies and a Denmark-based company, Ferrosan Medical Devices A/S, created a spray coating that includes …
1. Cameco today announced it has reached the main mine workings with the second shaft at the Cigar Lake uranium mining project in northern Saskatchewan. Miners removed the final section of rock connecting shaft 2 with the mine workings 480 metres below surface on January 3, 2012. The second shaft will provide for increased ventilation …
Agency Director Regina Dugan and Deputy Director Ken Gabriel spoke at MIT about revitalizing U.S. manufacturing. DARPA Director Regina Dugan focused also on the importance of a revitalized national manufacturing mentality. Of DARPA’s perspective on technology development, she said, “We can’t predict the future, but we can build it.” She stressed that the question was …
Imec and Holst Centre announce that they have made a micromachined harvester for vibration energy with a record output power of 489µW. Measurements and simulation show that the harvester is also suited for shock-induced energy harvesting in car tires, where it could power built-in sensors. In a tire, at 70km/h, the new device can deliver …
UK Guardian – Christopher Busby, a visiting professor at the University of Ulster, is championing a series of expensive products and services which, he claims, will protect people in Japan from the effects of radiation. Among them are mineral supplements on sale for ￥5,800 (£48) a bottle, urine tests for radioactive contaminants for ￥98,000 (£808) …
1. The Atlantic – Walmart and China have launched a bold experiment in consumer behavior and environmental stewardship: to set green standards for 20,000 suppliers making several hundred thousand items sold to billions of shoppers worldwide. With some 30,000 Chinese factories making things for Walmart, the company’s future was tied to China in the most …
Optimal asymmetric 1 → 4 quantum cloning in arbitrary dimension We present an optimal asymmetric 1 → 4 quantum cloner. Our derivation generalizes the constructions of optimal asymmetric 1 → 2 and 1 → 3 quantum cloners in [Quantum Inf. Comput 5, 583 (2005)]. We explicitly prove the optimality of this cloner and give the …
American Journal of Transplantation – Bioartificial Lung Engineering End-stage lung disease is a major health care challenge. Lung transplantation remains the definitive treatment, yet rejection and donor organ shortage limit its broader clinical impact. Engineering bioartificial lung grafts from patient-derived cells could theoretically lead to alternative treatment strategies. Although many challenges on the way to …
Arxiv – Adaptive on-chip control of nano-optical fields with optoplasmonic vortex nanogates (11 pages) A major challenge for plasmonics as an enabling technology for quantum information processing is the realization of active spatio-temporal control of light on the nanoscale. The use of phase-shaped pulses or beams enforces specific requirements for on-chip integration and imposes strict …
Microsoft offers a glimpse into what they see as the future of productivity in 2016-2021. (H/T KurzweilAI) All of the ideas in the video are based on real technology. Some of the capabilities, such as speech recognition, real time collaboration and data visualization already exist today. Others are not yet available in specific products, but …
The writer and columnist Sonia Arrison has recently published 100 plus in which she describes the coming “age of longevity”. Arrison argues that the fields of tissue engineering , as well as gene therapy and stem cell research, are experiencing rapid growth. In an interview with Sander Olson, Arrison discusses why longevity research will be …
