Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies — it sounds daring, but Prof. André Füzfa of Namur University has proposed just that in an article published in the scientific journal Physical Review D. If followed, this proposal could transform physics and shake up Einstein’s theory of general relativity.
At present, scientists study gravitational fields passively: they observe and try to understand existing gravitational fields produced by large inertial masses, such as stars or Earth, without being able to change them as is done, for example, with magnetic fields.
It was this frustration that led Füzfa to attempt a revolutionary approach: creating gravitational fields at will from well-controlled magnetic fields and observing how these magnetic fields could bend space-time.

“The vast majority of space technology being developed is dual-use, and so serves Chinese security interests as well,” says Johnson-Freese, an expert on the Chinese space program and a professor at the US Naval War College. “China understands the military advantages reaped by US space capabilities for many years, and wants those same capabilities”.

Whether you believe the buzz about artificial intelligence is merely hype or that the technology represents the future, something undeniable is happening. Researchers are more easily solving decades-long problems like teaching computers to recognize images and understanding speech at a rapid space, and companies like Google goog and Facebook fb are pouring millions of dollars into their own related projects.
What could possibly go wrong?
For one thing, advances in artificial intelligence could eventually lead to unforeseen consequences. University of California at Berkeley professor Stuart Russell is concerned that powerful computers powered by artificial intelligence, or AI, could unintentionally create problems that humans cannot predict.

Aside from the attention it receives around one of its rare solar transits, Venus hardly makes headlines.
But before our warming sun turned Venus into a poster child for the dangers of a runaway greenhouse, our closest planetary neighbor may have once had oceans capable of harboring complex life.

The future frontier for hackers is synthetic biology.
Landmark scientific projects such as the Human Genome Project can encourage international cooperation and bring nations together. However, when security interests and defence research align with the prestige of a landmark project—international competition is all but assured. Synthetic biology is a scientific discipline less than a decade old, and the potential defence and security applications may create a new space race, this time between the USA and China.
The larger concern is not that this race may happen, but that if it does it will politicise and militarise an ethically sensitive area of the life sciences at a time when this frontier technology is critical to maintaining a sustainable world.
The Human Genome Project (HGP) cost about US$300 million (A$394 million), involved 20 international institutions and sequenced the human genome in just over a decade. The draft sequence was published in February 2001 and has driven economic, health and social benefits the world over for the last 15 years. To a very large extent this research project underpins the modern life sciences and is the equivalent of landing on the moon.
