DNA Origami Self-Assembled Growth Details

This is a more detailed follow up to the original nextbigfuture article announcing the development of a method to grow DNA origami. This article discusses more details of the methods and error rates of what was done. This is a pathway to assembling larger complex molecularly precise structures. Recently there was success with the algorithmic …

IMEC integrates plasmon-based nanophotonic circuitry with state-of-the-art ICs

IMEC, Europe’s leading independent nanoelectronics research institute, reports a method to integrate high-speed CMOS electronics and nanophotonic circuitry based on plasmonic effects. Metal-based nanophotonics (plasmonics) can squeeze light into nanoscale structures that are much smaller than conventional optic components. Plasmonic technology, today still in an experimental stage, has the potential to be used in future …

World Health Organization Raises Pandemic threat Level to 5 out of 6

WHO Director General Margaret Chan told a news conference in Geneva as she raised the official alert level to phase 5, the last step before a pandemic. “The biggest question is this: how severe will the pandemic be, especially now at the start,” Chan said. But she added that the world “is better prepared for …

Helion Built One Third Scale Nuclear Fusion Engine. $20 Million For Full Scale Reactor in 2010-2011

Helion Energy has built a one third scale fusion generator and wants $20 million to build a full scale prototype by 2011. They would need another $100 million or so to build a first commercial version by 2019. Successful development of commercial nuclear fusion should revolutionize space travel, energy production and provide massive economic benefits …

Video Players with 25 Times the Resolution of High Def Demonstrated

Red Camera has developed a wavelet compression that compresses video by 700 times or more. The Red 400 original files were mastered as 16bit TIFFs (4096×2304), roughly 51MBs per frame. That’s an uncompressed data rate of 1.3GBs per second. Blu-Ray is 1440X1080 and has 1920×1080 as well. So the Red 400 is about 5-6 times …

Optical Wavelength Cloaking Carpets

Michal Lipson and pals at Cornell University and Xiang Zhang and buddies at UC Berkeley say they have both built cloaks that are essentially mirrors with a tiny bump in which an object can hide. The cloaking occurs because the mirrors look entirely flat. The bump is hidden by a pattern of tiny silicon nanopillars …

Ultrasound Imaging with Smartphones

The image of Zar’s carotid artery appears on this small, portable smartphone connected to the probe by a USB driver. William D. Richard, Ph.D., WUSTL (Washington University of St Louis) associate professor of computer science and engineering, and David Zar, research associate in computer science and engineering, have made commercial USB ultrasound probes compatible with …

Researchers at the University of Illinois have developed a nanoneedle to Inject into Living Cells

Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition to ferrying tiny amounts of cargo, the nanoneedle can also be used as an electrochemical probe and as an optical biosensor. Supporting information for …
