Microsoft co-founder Bill Gates confirmed Wednesday he is in discussions with China to jointly develop a new and safer kind of nuclear reactor. UPDATE – MIT Technology Review – Terrapower says that it is just having discussions with China. It’s also talking to other countries, as well as with two research centers in India. “We …
It is commonly believed that the fundamental limit to MOSFET feature-size scaling is direct source-drain tunneling. We may hit this limitation around the 5nm node. For CMOS logic transistors, when we approach the direct source-drain tunneling limit, we could move to recessed channel devices and use channel lengths longer than the minimum feature size. This …
International Energy Agency Oil Market report for August, 2011 World oil supply rose by 1.0 mb/d in August, to 89.1 mb/d, with non-OPEC production up by 0.8 mb/d. Rising US and Latin American production offset heavy maintenance and field outages in the North Sea. Non-OPEC supply has been revised lower to 52.8 mb/d in 2011 …
A study by Chris Cherry, assistant professor in civil and environmental engineering (University of Tennessee), found that solar power heavily reliant on lead batteries has the potential to release more than 2.4 million tons of lead pollution in China and India. Lead poisoning causes numerous adverse health effects, including damage to the central nervous system, …
A Kansas State University professor is trying to create a patient-friendly treatment to help the more than 220,000 people who are diagnosed with lung cancer each year. Tamura has focused his research on peptide nanoparticle-based gene therapy, which is the process of treating diseases by introducing therapeutic genes. His research team is collaborating with University …
The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics This may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state electronics that interface with biological systems. Networks of bacterial filaments, known as microbial …
Nature Photonics – Single-cell biological lasers Since their invention some 50 years ago, lasers have made a tremendous impact on modern science and technology. Nevertheless, lasing has so far relied on artificial or engineered optical gain materials, such as doped crystals, semiconductors, synthetic dyes and purified gases. Here, we show that fluorescent proteins in cells …

1. China daily has a debate about high speed rail in China. Against more high speed rail is the need for more freight rail capacity Low population density is a serious problem that development of high-speed railways in the western region faces. Considering its price and speed, high-speed railway is more competitive than flights for …
Two years ago we discussed water proof sand and how it will be used to turn deserts green Waterproof sand – or as German scientist Helmut F. Schulze calls it – hydrophobic sand, a nanotechnology wonder seven years in the making. By simply laying down a 10-centimeter blanket of DIME Hydrophobic Materials sand beneath typical …
