SpaceX Has Invested $500 Million

Wall Street Journal – Space Exploration Technologies Corp. said on Wednesday it has invested about $500 million in commercial-space ventures, shedding light on the closely held company’s efforts to develop private rockets and capsules even as congressional skepticism about such projects grows. The figure is substantially larger than founder and Chief Executive Elon Musk previously …

Using imprint processing to mass-produce tiny antennas could improve wireless electronics

A hemisphere-shaped antenna developed at the University of Michigan has the capacity to be mass produced and could lead to improvements in wireless consumer electronics. Credit: Carl Pfeiffer Engineering researchers at the University of Michigan have found a way to mass-produce antennas so small that they approach the fundamental minimum size limit for their bandwidth, …

20 megawatt wind turbine designs based on modified conventional designs could be built by 2020

20 Megawatt wind turbines are feasible, according to a new report from the EU-funded UpWind project, published at the EWEA 2011 Annual Event in Brussels. The UpWind project explored the design limits of upscaling wind turbines to 20 Megawatt (MW) and found that they would have rotor diameters of around 200 metres, compared to some …

Graphene Cloak Protects Bacteria, Leading to Better Images

Vikas Berry, assistant professor of chemical engineering at Kansas State University, and his research team are wrapping bacteria with graphene to address current challenges with imaging bacteria under electron microscopes. Berry’s method creates a carbon cloak that protects the bacteria, allowing them to be imaged at their natural size and increasing the image’s resolution. Nanoletters …

Silicon Spin Transistors Progressing to Room Temperature Spintronics

a dozen three-contact nickel-iron transistors sit on a silicon chip coated with an ultrathin film of magnesium oxide. Right, a six-transistor chip attached to electrical contacts for experiments showing that the magnetic “spins” of electrons can be aligned as they travel through silicon at room temperature — a step toward “spintronic” computers and other devices …
