Join Dr Karl Kruszelnicki, Lucy Smith and their scientific guests, with a bunch of curious triple j listeners for a weekly injection of science, myth-bashing and answers!
-
Microplastics, genetic modification and fire vs ice
If all planets are stuck in the sun's gravitational pull, what stops them from being completely pulled into the sun? Does melting cheese change its nutritional value? And could we genetically modify before birth?
Dr Karl answers these questions and more on triple j Mornings with Lucy Smith. -
Harnessing earthquakes, dog bellybuttons and baby clouds
Can we harness the power of earthquakes? Why don't dogs have bellybuttons like us? And why tf do you sometimes see one little cloud in a clear sky?
Dr Karl answers these questions and more, on triple j Mornings with Ruby Miles. -
Irrational phobias, earthquakes and mathematics
What kind of math formulas go into AI? What influences our biggest fears? And can humans acclimatise to every weather condition?
Dr Karl and special guest Tom Crawford answer these questions and more, on triple j Mornings with Lucy Smith. -
Aurora australis, op shop smells and photographic memory
Can eating certain foods change the taste of bodily fluids? Why do I get congested after a night out drinking? And why does armpit hair stop growing at a certain length?
Dr Karl answers these questions and more on triple j Mornings with Lucy Smith. -
BONUS EP: Space farts, dog breath and the Laws of Entropy
If the whole population stood in one spot and ran would the earth spin like a treadmill? What would happen if gravity didn’t exist? And are farts powerful enough to propel you in space?
Dave from Glass Animals asks these questions and more on this bonus episode of Science with Dr Karl. -
Wine sneezes, yawning vs. swallowing and dimensions...
What's actually happening when you get the wind knocked out of you? Why does swallowing combat yawning? And could we ever visualise someone else's pain?
Dr Karl answers these questions and more on triple j Mornings with Lucy Smith.
Customer Reviews
Answer & question session & no, I’m not dyslectic…
Firstly, the answer- the review, Great Podcast & I gain something from every episode. Secondly, the question- if humans surviving on Mars is problematic as the atmosphere is mostly carbon dioxide, why can’t the numerous spaceships that circle it release loose tree seed continually as the research ships orbit the planet in order to fast track the terraforming process as trees love carbon dioxide so much they extract the carbon which would leave the Mars atmosphere full of the remaining “O” molecules, which can’t be a bad thing for humans over time & as the seeds that love C02 sprout roots & grow there will be many parts of the trees that would be useful to the earthling population. Australian eucalyptus trees are particularly hardy & adaptable to huge temperature swings & there are a number of other tree varieties that grow on rocks, so is it in any way a viable way to mass produce Oxygen & they neatly store the extracted Carbon in their trunks, etc. I put this proposition to a NASA Scientist on their question page 3 years ago & they still haven’t answered me. I watched a deGrasse Tyson Podcast last night & he was posed the question of whether we can terraform Mars as climate change/global warming is destroying the earth & his reply was a suggestion in that, if Scientists have the ability to terraform Mars, why don’t they simply terraform Earth…!! deGrasse Tyson also threw me with his reply to a question on the expanding universe & he responded by extrapolation the expanding Universe to a point where at one stage “Time will stand still”…!! Dr Karl, could you explain that…. On the other hand & unrelated to the above, I noticed on the NASA Voyagers online dashboard that the almost real time miles from earth gauge was spinning backwards meaning that it was getting closer to earth at a rate of approx 34,000 mph & not as most people would think, always getting further from earth by the hour. I emailed the NASA Scientist question page questioning whether the Voyagers dashboard had a software glitch as I thought that for 47 years the Voyagers were heading away from earth & the Scientists reply was, no, the Dashboard gauge is correct & the Voyagers are often getting closer to Earth by the hour, Cheers, Steve, Gymea, Sydney…

Urination
Many questions get doubled and tripled up and more over the years, but why has no one asked why shaking your leg can hold urination urge at bay for a time? When you urgently need to go but can’t. Otherwise a great podcast and I’m too shy to phone in and ask any questions. Lucy and Karl intimate me, but they are nice people.
