As we get ready for the Olympics starting in Beijing, the games pose us a bit of a problem. A global event like this should be a gift to a news channel with an audience around the world. All those countries participating, all that action to report on. The trouble is, we can only show tiny snapshots of that action. 

The broadcasting rights are tightly restricted by the IOC, who've sold the rights to individual broadcasters in dozens of countries. Channels like BBC World News, beamed across the world, are therefore confined to showing a total of just one minute's worth of pictures within our bulletins - and even then not until after midnight of the day that the events took place.

Our answer is My Games - a live interactive TV and online show hosted by Adnan Nawaz from Beijing that taps into the views and passions of fans from all over the world, and cunningly avoids the need to show any official Olympics pictures.

AOL drags Time Warner income down

AOL continued to weigh on Time Warner as the media group reported a 26 percent drop in second-quarter income on Wednesday, largely because of weakness at its internet division.

AOL, which has emerged as the biggest challenge confronting Jeff Bewkes, chief executive, suffered a drop of 36 percent in operating income as as it continued to shed paying subscribers. Advertising revenue, which AOL is banking on as its future, rose only 2 per cent.

Mr Bewkes blamed the performance on difficulties from integrating the acquisitions that AOL had made since announcing an advertising-focused strategy two years ago.

He expressed optimism for the remainder of the year. Yet Mr Bewkes also noted that Time Warner had arranged for the separation of AOL's internet access business and its online advertising platform – a move that could hasten a potential sale.

With finesse

The Australian research team was interested in how a cartilaginous jaw performs compared with a bone jaw.

The scientists' study shows that the cartilaginous jaw is almost as strong as a bony jaw of the same size - losing only a few percent - in measures of bite force. What is more, the elasticity of the cartilage jaw increases the gape of the sharks to devastating ends.

"The shark's upper jaws can be dislocated: the whole upper and lower jaw pull out and forward as the shark twists and shakes its head from side to side to bite a chunk out of its prey," explains Dr Wroe.

Sharks feed on very large prey: the great white shark eats sea lions and the megalodon is thought to have eaten whales.

The great white shark may have awesome jaws but they are nothing compared with those of megalodon, its gigantic, whale-eating ancestor. 

A new study of the extinct creature's skull shows it had an almighty bite, making the prehistoric fish one of the most fearsome predators of all time. 

All the more remarkable, scientists say, because the crushing force came from jaws made of cartilage, not bone. 

Primates 'face extinction crisis' 
By Mark Kinver

A global review of the world's Primates says 48% of species face extinction, an outlook described as "depressing" by conservationists. 
The IUCN Red List of Threatened Species says the main threat is habitat loss, primarily through the burning and clearing of tropical forests. 

After four years at Newsnight this is my final editor's blog. I'm off to Google, which has provoked some head scratching in the blogosphere.

My reasoning was pretty straightforward - I was looking for something at least as interesting, eventful and as much fun as Newsnight. That leaves a short list of options.

Experimenting with new media has been one of the joys of running Newsnight. There have been new products and possibilities almost every week. We've piled into many of them although so far, unlike Downing Street, we've resisted Twitter.

Some of our wheezes proved controversial but four years on I don't think anyone - and certainly not Jeremy - would argue that Newsnight should be simply a TV programme shown once at 10.30pm.

The digital revolution means I've been the first Newsnight editor to look after a programme which can be accessed at any time of the day or night anywhere in the world. You can engage us in conversation and we can - and should - explain our inner thinking.

The decades-old footage of a full-grown lion joyously embracing two young men like an affectionate house cat has made myriad eyes misty since it recently landed on YouTube. What is it about the old, grainy images that has attracted millions of clicks around the globe?

Is it simply that a lion, whimsically named Christian, remembered the two men who raised it and then released it into the wild?
