The high school comedy drama Glee is to leave free-to-air TV in the autumn and will be screened on Sky. The first two series of the US show were on digital channel E4, but parent company Channel 4 walked away from negotiations on the rights to broadcast the show last month. All future series will be shown on Sky 1 HD.

In 2009, the BBC broadcast a Panorama special, A Very Dangerous Doctor, about Dr David Southall, the controversial paediatrician repeatedly struck off by the General Medical Council. And now, here's Channel 4 with its very own version. The name's the same: A Very Dangerous Doctor. The star's the same: Dr Southall – older, plumper, more wild-eyed than last time – but the allegations against him are different. Different, not new.

A new television series is to broadcast volunteers taking Class A drugs live on air. The Channel 4 programme, called Drugs Live, will show participants taking drugs such as ecstasy under clinical conditions, so viewers are able to see how they affect the body.

People will take Class A drugs live on television in a new programme to be broadcast by Channel 4, it was announced.

Far be it for me to hog all the exclusives, but there's a, uh, wedding on the go. Something to do with the royals, you know, Wills and Kate, love story of the century etc etc. In case you hadn't noticed – entirely possible, of course, because it's all been terribly under the radar – the television gods have been offering a few (subtle) hints. We've had When Kate Met William: a Tale of Two Lives (ITV1), William and Kate: the Story So Far (Channel 5), Kate and William: Romance and the Royals (Channel 4). On Wednesday night we were given the dubious honour of watching Giles Coren and Sue Perkins in fancy dress in Giles & Sue's Royal Wedding (BBC2). Naturally, there was one thing remaining: My Big Fat Royal Gypsy Wedding.

The influential parenting forum Mumsnet is to expand from the internet to a television series in which members give advice to mothers.

I would really not like to find anyone's pubic hair anywhere, thank you," remarked Frances Young, owner of Stoberry Park bed and breakfast. Ah, the irony. She is to be undone by such a follicle, lingering in the corner of a shower, just a few short hours later. But in the meantime, welcome back, Three in a Bed, the latest voyeuristic hybrid to reach our screens courtesy of Channel 4. Voyeuristic, but not bad. Part Come Dine with Me, part Ideal Home, it's a guilty pleasure of considerable proportions.

They're not exactly picky eaters, hyenas. If you want proof try to catch up with The Elephant: Life after Death, a novel kind of natural-history programme in which a group of biologists and film-makers laid on a free buffet for the scavengers and detritivores of Tsavo West National Park in Kenya. Staked out in a clearing, surrounded by more remote-control cameras than a sink-estate crime spot, was the corpse of a male elephant – six million calories of fat, meat and guts just waiting for anything bold enough to come and claim a chunk. The hyena was the first guest to show up, looming unnervingly out of the blackness with its headlamp eyes. Half-a-mile away, in a tented control room, the scientists sat in front of a bank of monitors giving a running commentary. Very tough, the skin of an elephant, they reminded us, as the hyena circled warily. Even a hyena's immensely powerful jaws will struggle. He's most likely to go for the softer parts. At which point – after one last quick check around for lions – the hyena took a little run-up and jammed his head up to the shoulder blades in the elephant's rectum. I'm glad to say that even the biologists momentarily lost their scientific detachment at this point. "Urggh!" they said as one, and they all said it again a little later when the hyena's enthusiastic tugging triggered a sudden explosion of intestinal gas.
