During the 20th century, science unlocked the secrets of the atom, created the computer and unravelled the molecule of life, DNA. That puts us on the threshold of a shift from an age of discovery to an age of mastery, according to physicist Professor Michio Kaku.
The world's last unexplored frontier - the ocean - could soon be home to swarms of tiny submarines, moving together like schools of fish as they probe the depths.
Code-makers could be on the verge of winning their ancient arms race with code-breakers. After 20 years of research, an encryption process is emerging that is considered unbreakable because it employs the mind-blowing laws of quantum physics.
The U.S. military is working on "sleeping" UAV weapons that could be deployed near a target and programmed to "awake" only when the target came within range.
Australia's merciless sunshine is about to be harnessed to produce massive amounts of renewable energy. As part of the process, the tallest man-made structure built, a one-kilometre-tall solar-thermal tower, will rise from the red desert in the south-west of New South Wales.
For help in fighting the war on terrorism, the U.S. military has turned to the Institute for Creative Technology, a movie industry think tank, for help in imagining possible worst-case scenarios.
In the next century, man-made hazards such as germ terrorism will drive humans to colonise space for survival, Britain's Astronomer Royal, Sir Martin Rees, said yesterday. "There are various ways waiting for us to snuff ourselves out, by design or misadventure," he said - and the key was to colonise space before disaster struck.
A political skirmish betwwen the U.S. and China ignites a proxy battle between hackers on both sides.
The Age surveys the research being done by Australian researchers into quantum computing.
Dr. Damien Broderick considers the implications of new advances in life extension research.
