NASA begins releasing Martian lander's robotic arm (Science/Technology, 15 articles)
|
Scientists began releasing the robotic arm on NASA's new Mars spacecraft on Wednesday, one day late because of a radio problem. Nasa's Mars lander Phoenix has unstowed its robotic arm - the key tool in its mission to test the red planet's soil for the building blocks of life. After a dramatic deceleration through Mars's thin atmosphere that ended with a gentle landing in welcoming rock-free terrain, NASA's Phoenix mission now stands ready to go to work. " Everything just worked like a charm says Barry Goldstein which ran mission control for the landing. The first weather reports are in from Canada's $37-million weather station on Mars, showing temperatures hitting a high of - 30 Celsius and a low of - 80. The red tundra of the Martian north pole has been revealed for the first time, in remarkable images captured by a Nasa spacecraft yesterday after its 423-million-mile journey ended with a perfect landing. The spacecraft has redundant systems to survive the failure of some components, and mission controllers have drawn up contingency plans for possible problems.

Monkey learns to master robotic arm with brain impulses (Science/Technology, 4 articles)
|
Monkeys have learnt to feed themselves using a robotic arm controlled by their thoughts, in an experiment that could ultimately help paralysed people and amputees to lead more independent lives. The success is by far the best demonstration yet of a technology that promises to transform the quality of life of patients paralysed by spinal injuries, strokes or wasting conditions such as motor neuron disease. Scientists expect that technology will eventually allow people with spinal cord injuries and other paralyzing conditions to gain more control over their lives.

Gum Disease Might Boost Cancer Risk (Science/Technology, 8 articles)
|
The initiative's purpose is to raise funds to accelerate cancer research, and all three major television networks have agreed to donate a simultaneous hour of commercial-free primetime programming for a special at 8 p.m. on Sept. 5. More than 60% of adults with cancer can expect to live five years or more, according to an article in the European Journal of Cancer. The rare simultaneous broadcast is reminiscent of a benefit for the Sept. 11 terrorist attacks that was shown on many networks weeks later.
