Economist magazine wants more spent to verify safety of nanoparticles

The Economist has a lengthy article that suggests that more money and effort should be sent to verify the safety of nanoparticles. America already spends the most on EHS (environmental health and safety) research into nanotechnology. Depending on who does the counting, it ranges from $11m to $60m. Safety legislation cannot be expected to work …

Der Spiegel indicates radiation deaths are exaggerated

About 4,000 children were afflicted with cancer after Chernobyl. Less well-known, however, is the fact that only nine of those 4,000 died — thyroid cancers are often easy to operate on. Officially 47 people — members of the emergency rescue crews — died in Chernobyl from exposure to lethal doses of radiation. This is serious …

Help hookup.com, an army of volunteers

The inspiration of Help Hookup is actually a comic book called Global Frequency by Warren Ellis. My brother, Alvin Wang, took the idea to startup weekend and they launched the idea this past weekend for hooking up volunteers. It is similar to the concepts of David Brin’s “empowered citizens” and Glenn Reynolds “an army of …

New method to manipulate light a million times more efficiently

Using a special hollow-core photonic crystal fibre, a team at the University of Bath, UK, has opened the door to what could prove to be a new sub-branch of photonics, the science of light guidance and trapping. The team, led by Dr Fetah Benabid, reports on the discovery, which relates to the emerging attotechnology, the …

China taking leadership in renewable power deployment

Worldwatch indicates that China will likely achieve—and may even exceed—its target to obtain 15 percent of its energy from renewables by 2020. If China’s commitment to diversifying its energy supply and becoming a global leader in renewables manufacturing persists, renewable energy could provide over 30 percent of the nation’s energy by 2050. China’s carbon dioxide …

32 megajoule rail gun delivered for naval testing

BAE Systems has delivered a functional, 32-megajoule Electro-Magnetic Laboratory Rail Gun (32-MJ LRG) to the U.S. Naval Surface Warfare Center in Dahlgren, Va. Installation of the laboratory launcher is currently underway, and according to BAE, this is the first step toward the Navy’s goal of developing a tactical 64-megajoule ship-mounted weapon. Eight and 9-megajoule rail …

Other progress in quantum computing

Other Quantum computer progress discussed at SC07 The quest to build fully functioning quantum hardware is active on many fronts. Atomic physicists have seen for some years that the quantum states of a single atom held at rest in a trap, manipulated by laser pulses, functions as a highly coherent quantum information carrier. The ability …
