Five must-read stories from the past week

Surprising health findings, massive cosmic collisions, and The Weather Network's long-awaited Summer Outlook. Here are five stories on our website that we thought were popular enough to warrant a second look.

5. Neurosurgeon says bike helmets don't work

The conventional wisdom (and, in most places, the law) says to wear your helmet when you're roaming on two wheels, but one researcher says you may be wasting your time.

Neurosurgeon Michael Marsh says the science doesn't back up the helmets' safety claims.

"I ride a bike and I never wear a helmet. In the countries where bike helmets are compulsory there has been no reduction in bike injuries whatsoever," Dr. Marsh also apparently said. "I see lots of people in bike accidents and these flimsy little helmets don't help."

He's not the only one saying so, but safety advocates say Marsh's comments are irresponsible.

4. Lasers can fix your teeth

Nobody relishes a trip to the dentist, and this week, the news came down that researchers may be proscribing lasers to fix teeth.

A team of scientists at Harvard pointed their specialized laser at the damaged tooth of a rat and found the dentin -- the material at the core of the tooth -- grew back more than it would have without medical intervention.

"It would be a substantial advance in the field if we can regenerate teeth rather than replace them," said David Mooney, the study's lead author.

The researchers hope to begin clinical trials soon. Get the full story here.

3. A young Earth may have been slammed by another planet

Gazing up at the night sky, there's new evidence the moon that hits your eye may have come about because our Earth got hit by another planet.

It's a long-standing theory, but evidence of the massive collision billions of years ago emerged this week.

Dubbed "Theia," remnants of the hypothetical planet-sized rock could make up as much as 50 per cent of our moon's mass, with the other 50 per cent coming from pre-collision Earth.

2. A 12-billion-year-old burst of light

Less destructive, and certainly much older, was the 12 billion-year-old cosmic explosion whose light reached our planet for the first time recently.

The light, which is a gamma-ray burst, was detected at 11 p.m. local time on April 19, 2014 by a robotic telescope owned by Southern Methodist University in Dallas, Texas.

Scientists say the 12-billion year old light burst was bright enough to be seen in our night sky.

1. The Weather Network's Summer Outlook

The past winter (and slow start to spring), may have had people doubting summer was actually on its way, but it certainly is, and The Weather Network released its 2014 Summer Outlook on Tuesday.

The video up above features our Chief Meteorologist, Chris Scott, giving us a peek at what the whole country can expect, but we've also narrowed it down region-by-region

Read the national outlook here, and follow the links within to your own home region.
