Jun 27: The Quirks & Quarks listener question show

We answer your questions, like: do wildfires near Chernobyl release radiation? Do birds fly south for the summer in the southern hemisphere? How much does an airplane grows and shrink as it flies?

Bob McDonald's blog: We may not be travelling much this summer, but there's lots going on above us

Jun 20: A cosmic iceberg visitation, female genetic superiority and more…

A megadrought in the southwest and science fights Lyme disease invading Quebec.

There may be 36 other intelligent civilizations in the galaxy, but odds of communicating with them are small

'Oumuamua could be a relic from giant clouds where stars are born

The mysterious interstellar visitor could be 'a new type of astrophysical object'

Female genetic superiority: when it comes to survival, two X chromosomes beat an X and a Y

In his new book ‘Better Half’, Dr. Sharon Moalem explains the survival advantage that allows women to better overcome biological challenges throughout their lives than men.

Megadrought: will the southwest part of North America be parched for decades?

Climate change could push the area into the worst megadrought in a 1,200 years

As climate warms and tick populations grow, Quebec turns to science to combat rising rates of Lyme disease

Warmer weather conditions allow disease-carrying ticks to reproduce faster while gradually migrating north by hitching rides on their hosts — mice, birds, deer and other animals, including humans. As a result, Lyme disease has become a far more pressing public health issue in parts of Quebec than it has ever been before.

Is it ethical to go to the red planet?

We consider possible harm to Mars, whether it's ethical to ask astronauts to go on such a dangerous trip, and the potential moral hazards around terraforming and 'colonizing' another planet.

AI sources fossil poop, and the insect apocalypse

A beacon of hope on World Oceans Day

Bob McDonald's blog: Social media movements focusing on conservation success stories may help restore motivation in the face of often negative news

The key to early detection of COVID-19 outbreaks might be in sewage

'We may actually start seeing genetic signals of the virus up to a week prior to its manifestation within the community.'

SpaceX takes humans to orbit, but who loses in the new landscape of space launch?

SpaceX seems to have won the private race to put humans in space, and competitors like Boeing and the Russian space program could be put in an awkward place.

Experiment shows dogs might be willing to help you in a crisis, but they probably aren't able

Dogs showed anxiety in a situation where their owners were trapped, but most couldn't free them.

Machine learning helps archaeologists identify the source of ancient poop

Ancient feces can be a gold mine of information. But only if scientists know what left it behind.

Can we avoid an 'insect apocalypse' with a new appreciation for creepy-crawlies?

A new study looks at the global health of insect populations, and a new book calls for us to re-think our relationship with bugs in order to help save them.
