Clinical trials in 2007 for nanoparticle cancer treatment

The first in a new generation of nanotechnology-based cancer treatments will likely begin clinical trials in 2007, and if the promise of animal trials carries through to human trials, these treatments will transform cancer therapy. One of these new approaches places gold-coated nanoparticles, called nanoshells, inside tumors and then heats them with infrared light until …

New state of matter quantum spin Hall state could make better computers

three Stanford researchers proposed that a new state, called the quantum spin Hall effect, could be realized without applying an external magnetic field. Since quantum wells in mercury telluride/cadmium telluride sheets can be readily fabricated, it is possible to experimentally test the theoretical predictions of Zhang, Bernevig and Hughes. A research group at the University …

Indian President Kalam wants two thirds of nuclear fuel from Thorium

India is targeting 24 GW on nuclear power by 2020 and 50 GW by 2030. Two thirds of the nuclear fuel should be thorium. As per the present plan of the Bhabha Atomic Research Corporation (BARC) and the Nuclear Power Corporation, the capacity by 2020 is expected to be increased to 24,000 MW. ‘There is …

Colonizing space going slower and closer

Stephen Hawking told a BBC radio audience that if the human race were to survive, it would be necessary to go to another star. Hawking talked about using antimatter powered spaceships to go at about 86% of light speed. This is the second part of my analysis. In the first part, I talked about going …

Reduce drag for faster and more efficient ships

The New Scientist, examines the efforts to reduce ship drag using tiny bubbles, slippery polymers and trapped sheets of air. As a ship moves through water it encounters three types of drag: wave drag, pressure drag and frictional drag. Wave resistance is mainly a problem at high speed, and can be minimised with a carefully …

More from the Steve Chen Supercomputer Interview

The Chinese government supports university research and gives them money to pay for the use of the service [supercomputer grid]. That is better than to spend money on buying thousands of separate smaller systems and none of them can do significant work. China only has two supercomputer centers now. Steve Chen is recommending and apparently …
