Why are opossums immune to snake bites? And what's the deal with tasting stuff? Dr Alice Williamson joined Ruby Miles to answer some of these pressing questions.

Dr Alice Williamson came into the studio to tell us about dinosaur dandruff and the asteroid that wiped them out.

Dr. Alice Williamson joined us to confirm our greatest fear (hand driers are spraying poop onto our fingers), and to teach us about green blooded lizards.

Dr Alice Williamson joined Ruby to talk all things brains. We learned that Google DeepMind has developed an internal satnav (all by itself?!), and about Neanderthal brains that are being grown in petri dishes.

Dr. Alice Williamson has finally returned so we can bask in her sciencey glory. It's not all good news though. We talked flesh eating ulcers, and the people who search the sea floor for medicine.

Dr. Alice Williamson is still out of sorts, so Tom Gordon joined us to talk protein caps on DNA and special plastic.

Dr. Alice Williamson is recovering, so our backup scientist Tom Gordon swooped in to save the day. He told us all about a spacecraft on the hunt for alien planets, and tiny robots who can fix your cells from the inside.

We're cursed! Dr Alice Williamson tripped over some loose science on the floor and needed to call in from home. Luckily we still got our knowledge fix, learning about laser beam tweezers and their impact on quantum computers.

Dr Alice Williamson returns to the studio to talk wasp drumming and seriously killer whales.

Tom Gordon joined us for a second week to talk the physics of ball tampering and meat grown in petri dishes.

Dr. Alice Williamson is taking the week off, so Ruby was joined by Tom Gordon, who talked Pi Day, the speed of galaxy’s rotations, and batteries that run on water.

Dr. Alice Williamson joined Ruby to talk (potentially) Alzheimers curing light, and how polar bear fur can make bunnies invisible.

Dr. Alice Williamson is joined by Chemistry PhD candidate Kate Leslie for this International Women's Day special to talk fluorescent dye in cells and the end of cervical cancer.

Dr Alice Williamson is making science cool again with this chilly Winter Olympics Special. She talks plastic ice and quintuple spins on Up For It with Ruby Miles.

Dr Alice Williamson joined Ruby today, and we learned that magpies in larger groups are smarter, ecologists are planting prairies in our cities, and that somewhere out there is the loneliest frog in the world. http://www.abc.net.au/news/science/2018-02-08/australian-magpie-brain-power-boosted-by-group-size/9401674 https://www.theatlantic.com/science/archive/2018/02/vacant-lot-ecological-experiments/552746/ http://www.bbc.com/news/world-latin-america-43004367

Dr Alice Williamson discussed Australian of the Year, quantum physicist Michelle Simmons, and talked jogging apps revealing secret US army bases. http://theconversation.com/award-to-michelle-simmons-reflects-strategic-importance-of-quantum-physics-for-australia-90759https://www.theguardian.com/world/2018/jan/28/fitness-tracking-app-gives-away-location-of-secret-us-army-bases

Dr Alice Williamson joins Ruby once again to talk bacteria that make gold nuggets, and how gamblers 600 years ago decided to make dice fair.

Dr Alice Williamson joined Ruby this morning to talk fire starting birds and a machine the size of a pill that could change diagnostic medicine as we know it.

Lucy Smith is officially wrapping up her time as host of Up For It, making way for a new presenter in 2018 after an incredible two years behind the mic. On her final edition of Up and Atom, Dr Alice Williamson quite literally put her to the test, submitting Lucy to her first science quiz since high school while recapping the biggest science stories covered on Up and Atom over the past year. Questions ranged from why Western Australians were asked to collect as many cane toads as possible, to who was awarded the 2017 Nobel Prize in Chemistry, and when the first-ever sighting of a gravitational wave event using conventional telescopes was. While Lucy may be moving on, Dr Alice will be back with more science in 2018.
