Hello, I'm Helen Mann.

Good evening, I'm Jeff Douglas.

This is As It Happens.

Tonight:

The wild, wild West. BC Premier Christy Clark and Alberta Premier Alison Redford are like oil and water where the Northern Gateway pipeline is concerned -- and tonight, Premier Clark gives us her side.

Get off my back. A grumpy gray whale gives a British Columbia couple a scare and a story, when it nearly tips their boat from underneath.

At the moment, he's not resting in peace. Cuban police show up and arrest dozens of dissidents at the funeral of a political activist.

I don't think you're ready for this jellyfish. A Harvard scientist tells us how and why he threw together a bunch of stuff to make a synthetic marine creature.

Finding her own space. Marc Garneau pays tribute to the late Sally Ride -- who overcame more than gravity to become the first female American astronaut.

And...running commentary. A physicist offers a complex answer to the eternal question of whether the best way to stay dry in a rainstorm is strolling or trotting -- even though no one's ever asked that question.

As It Happens, the Tuesday edition. Radio that figures he did some experimenting -- a few dry runs, if you will.

A war of words between B.C. Premier Christy Clark and Alberta Premier Alison Redford is coming to a head, just before the Premier's conference gets underway tomorrow in Halifax.

At issue is Enbridge's proposed Northern Gateway pipeline, which would transport crude from Alberta's oilsands to the Kitimat coast in British Columbia. Yesterday, the B.C. government announced five requirements that must be met before it will consider approving the Northern Gateway pipeline. But the Alberta premier has given a terse, cool response -- saying B.C.'s demands would, quote, "fundamentally change Confederation", unquote.

We reached B.C. Premier Christy Clark in Halifax, Nova Scotia.

It's called the "Medusoid". And one day, it just might save your broken heart.

Researchers at Harvard University have taken a rat's heart cells, attached them to an artificial jellyfish, zapped it with electricity, and reverse-engineered a living creature.

I think.

Kit Parker is the man leading the research, so we'll let him explain. He's a professor of bioengineering at Harvard, but we reached him at the Gordon Conference on Thin Film and Mechanical Behaviour, in Waterville, Maine.

She didn't just shatter the glass ceiling -- she rocketed through it at eighteen-thousand miles per hour.

Sally Ride, the first American woman to become an astronaut, died yesterday at her home in San Diego, from pancreatic cancer. She was sixty-one.

The physicist flew on the space shuttle Challenger twice, and later served on the boards of inquiry examining the explosions of both the Challenger and the Columbia.

Canadian astronaut and Member of Parliament Marc Garneau flew with Dr. Ride on her second mission in 1984. It was Mr. Garneau's first of three trips into space.

We reached Marc Garneau in Montreal.

Today, in Havana, hundreds of people attended Oswaldo Payá's funeral. And after the funeral was over, Cuban police arrested as many as fifty people -- including some high-profile dissidents.

Mr. Payá -- a well-known dissident himself-- died in a car crash on Sunday. The circumstances of his death have aroused suspicion, and many sympathizers wonder whether the crash was really an accident.

Orlando Pardo is a Cuban writer, blogger and photographer. He was at Mr. Payá's funeral today. We reached him in Havana.

Today, in Quebec City, Matthew Coon-Come -- the Crees' Grand Chief -- and Premier Jean Charest took pen to paper. And they changed the relationship between the province of Quebec and the James Bay territory.

The new agreement transforms the territory -- which until today was considered a municipality -- into a regional government run by Cree and non-native residents of the territory. And it gives the regional body more power over its resources.

Both men called the agreement historic, and a step forward in their relationship. Here's some of what Grand Chief Coon-Come had to say.

In the midst of the news coverage of the sex abuse scandal at Penn State University, many media outlets -- including "As It Happens" -- have been referring to the late Joe Paterno as the winningest coach in U.S. college football. We did so last night -- and then Talkback cried foul.

Fishing stories are notoriously trumped up with wild exaggerations -- the size of the fish, the intensity of the fight, the fortitude of the angler.

So forgive us if we ask Shirley Antonelli some tough questions.

She's come back from a two-day fishing trip with a whale of a story.

We reached Ms. Antonelli in Port Alberni, BC.

The question is a challenging one: when it starts to rain, and you want to stay dry, should you walk...or run?

Now, some of you just said, "run", and stopped listening. But wait. This question has vexed physicists and mathematicians for decades. Because --

Please, stop saying "run". Because here's the thing: staying dry in the rain is actually more complicated than you think. Apparently, it's the kind of problem that has inspired people to research it. For example: in 1987, a man named Alessandro de Angelis wrote a paper whose introduction read, in part,

"Even if common sense suggests running as fast as possible, it is frequently objected ... that nothing really changes, or maybe running gets people wetter. The purpose of this paper is to put an end to this kind of useless argument."

Mr. de Angelis's conclusion was, quote: "By running faster you get less wet, but the benefit that you get beyond the speed of a brisk walk does not justify the supplementary effort."

Mr. de Angelis's paper did not put an end to this kind of useless argument. Most recently -- last week, in fact -- a physicist named Franco Bocci published a paper called "Whether or not to run in the rain" in the European Journal of Physics. And Mr. Bocci really gets into it. He takes into account wind direction, raindrop size, something called "rain flux", and the size and shape of the body travelling through the downpour. He fills thirteen pages with complex charts, graphs and calbculations. And he concludes -- well, as you might expect, it's complicated. So complicated, in fact, that it's incomprehensible to the layperson.

So I'll quote Mr. Bocci, who told the BBC, "Let's say that, in general, the best thing is to run as fast as you can -- not always, but in general."

So I guess you people saying "run" were right, after all. But only in general.

"I am the first, and I believe the first of many people who will be cured of the AIDS virus."

That statement, made earlier today by Timothy Ray Brown, is music to the ears of millions of people on this planet battling HIV and AIDS. Mr. Brown, also known as the "Berlin Patient", spoke at a press conference today in Washington, DC, where the 2012 International AIDS Conference is being held.

He was diagnosed with AIDS seventeen years ago, and just a few years after that he was also diagnosed with leukemia. He says it was his leukemia treatment that holds the key to a cure for AIDS. This is what Timothy Ray Brown had to say at the press conference today, for the record.

And, finally, tonight, I guess you could say he's moved on up -- for good.

Sherman Hemsley, who played George Jefferson, the similarly opinionated and irascible foil to Archie Bunker on the 'Seventies sitcom All In The Family -- and later on his own show, The Jeffersons -- has died.

He was seventy-four.

In a twelve-year career in prime-time comedy, Hemsley's characteristic gait and witty comebacks made him one of the most recognizable characters in television.

Born in South Philadelphia, Hemsley dropped out of of school and joined the Air Force. After four years, he got a job at a post office and began taking acting lessons. He got his first Broadway gig in 1971, and spent much of 1972 in Toronto performing in the musical Sorry, I Can't Cope. The following year producer Norman Lear cast him in All In The Family, and he never looked back.

He retired from acting in 1999, although he made occassional appearances in ads for The Gap, Denny's and at -- incredibly -- dry cleaning conventions.

But for a generation of T-V watchers in its golden era of comedy, he will forever be George Jefferson, throwing sarcastic barbs and shouting at "Weezy."

So Sherman Hemsley, this one's for you:
