Imagine eating food that was cooked using natural gas generated from your own human waste. Thousands of prisoners in Rwanda don't have to imagine it -- they live it.
Scientist Professor Richard Dawkins has opened a global conference of big thinkers warning that our Universe may be just "too queer" to understand.
Professor Dawkins, the renowned Selfish Gene author from Oxford University, said we were living in a "middle world" reality that we have created.
Experts in design, technology, and entertainment have gathered in Oxford to share their ideas about our futures.
TED (Technology, Entertainment and Design) is already a top US event.
It is the first time the event, TED Global, has been held in Europe.
Japanese researchers have developed a durable new drug that blocks HIV from entering human cells and causes almost no side effects. The new drug, code named AK602, was unveiled by Hiroaki Mitsuya, leader of the research team at Kumamoto University, at the International Congress on AIDS in Asia and the Pacific in Kobe Tuesday, the Asahi Shimbun reported Wednesday.
The drug's main feature is that it shuts out the AIDS virus at the point when it tries to intrude into a human cell.
An underwater volcano is thought to be behind a huge column of steam above the Pacific Ocean, Japanese officials say.
The coast guard sent helicopters to monitor the 1,000m (3,280ft) cloud, 1,120km (700 miles) south-east of Tokyo, and warned ships to stay away.
The team said the area around the site appeared to be red.
"It's highly likely that it's caused by an eruption of an underwater volcano," coast guard spokesman Shigeyuki Sato said, adding it had happened before.
Comet Tempel 1 has smashed into the Deep Impact probe, producing a blast of light that prompted the mission control room at NASA's Jet Propulsion Laboratory in California, US, to erupt into cheers and applause.
Scientists and engineers jumped in the air, pumped their fists and hugged one another. Not only had their mission to deliberately collide with a comet for the first time succeeded perfectly, but the prospect of a damp squib - with the impactor passing right through a diffuse, rubbly comet - had fizzled away.
