Quantum Invisibility and Large Scale Invisibility Cloaks

1. Arxiv – Natural Light Cloaking for Aquatic and Terrestrial Creatures Hongsheng Chen at Zhejiang University in China and an international circle of friends have created large-scale invisibility cloaks that work over the entire optical spectrum but can cloak in several directions at once. Most animals cannot detect phase changes in light. Abandoning the requirement …

Thermoelectrics made from dirt cheap materials

By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material. This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It’s the thermoelectric material’s job …

US Navy now expects laser cannons on ships in Just Two Years Away

Wired Danger Room – ” Rear Adm. Matthew Klunder, the chief of the Office of Naval Research, the Navy’s chief futurist is pushing up the anticipated date for when sailors can expect to use laser weapons on the decks of their ships, and raising expectations for robotic submarines. The US Navy should have laser cannons …

6 billion mobile subscriptions and US$1.5 trillion global telecommunications revenue

New figures released today by ITU (International Telecommunications Union) show that information and communication technology (ICT) uptake continues to grow worldwide, spurred by a steady fall in the price of telephone and broadband Internet services. The new data, released in ITU’s flagship annual report Measuring the Information Society 2012, rank the Republic of Korea as …

Human Brain Project Awaiting February 2013 EU decision on 1 billion euro funding

The Blue Brain Project (BBP) and the Human Brain Project (HBP) are unique projects that overlap in some clear ways. This is not to say that the HBP will be a mere extension of the BBP but rather that the proposed HBP will be a large-scale project offering a solid opportunity to coordinate the work …

Imec presents a MEMS energy harvester suitable for shock-induced energy harvesting in car tires

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 …

Lair of a Giant 30 meter long Triassic Kraken (giant octopus) Discovered

At Berlin-Ichthyosaur State Park in Nevada is a site where the remains of nine 45-foot (14-meter) ichthyosaurs, of the species Shonisaurus popularis can be found. These were the Triassic’s counterpart to today’s predatory giant squid-eating sperm whales. The new thinking is that there was a Kraken (giant octopus) that preyed on the ichthyosaurs. They hypothesize …

IMF projects India’s GDP growth at 8.2% in 2011 and 7.8% in 2012 and China’s GDP growth at 9.6% in 2011 and 9.2% in 2012

The International Monetary Fund (IMF) today said that further increase in key policy rates and the base effect are likely to pull down India’s gross domestic product (GDP) to 8.2 per cent in 2011 and further down to 7.8 per cent in 2012 from a double-digit high of 10. 4 per cent in 2010. The …

Southampton scientists begin patient trials of new leukaemia cancer vaccine

A new cancer treatment which strengthens a patient’s immune system and enables them to fight the disease more effectively is being trialled on patients for the first time in the UK. The treatment will use a new DNA vaccine, developed by scientists from the University of Southampton, which will treat a selected group of volunteers …

Thermoelectrics could be improved from 5% to 20% effciency for heat to electricity conversion

Certain configurations of the filler element barium will be very effective in lowering the materials’ thermal conductivity and thus increasing their conversion efficiency. Today’s state-of-the-art thermoelectric materials are only five percent efficient. Skutterudites, and this new knowledge about how best to arrange their atoms, could help improve their performance to 15- or 20-percent, at which …
