Dr Steve Rintoul, Dr John Church and Dr Pep Canadell of CSIRO discuss our climate science research to understand how and why the Earth system is warming.
Water is a special substance for several reasons, and you may have noticed an important one right in your cold drink: ice. Solid ice floats in liquid water, which isn’t true for most substances. But why? George Zaidan and Charles Morton explain the science behind how how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat.
Like rings on a tree, human flesh can be dated in a consistent, reliable way. And as Trace tells us, this discovery could revolutionize medicine, and even enable us to extend life.
Science guy and leader of Thirst DC helps us understand how genes and DNA write the book of life, and how reading that book has helped us learn that everything on Earth is descended from a common ancestor.
They’ve finally found a fossilized mosquito full of prehistoric blood! So a real Jurassic Park is right around the corner, right? Trace explains what exactly this discovery means, and if this means you’ll be visiting Isla Nublar any time soon.
Hank profiles this year’s Nobel laureates in science, whose achievements have helped us understand questions as small as how our cells transport materials, and as big as why matter exists at all.
The Global Positioning System, or GPS, is pretty amazing and chances are, it’s playing a much greater role in your life than you realize. Anthony explains how GPS works and tells you about some pretty cool upgrades coming soon.
How does getting paid $18,000 for laying in bed sound? Well NASA’s ready to pay up! Laci explains why they’re willing to cut the check.
A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and minimize repulsion of unlike. George Zaidan and Charles Morton shape our image of molecules.
Robert Lawrence Kuhn poses the question to theoretical physicist Sean Carroll, in an interview from our series “Closer To Truth.”
We put three calculators through their paces with a series of special tests.
Atoms can (and do) bond constantly; it’s how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond. From simple oxygen to complex human chromosome 13, George Zaidan and Charles Morton break down the humble chemical bond.
Nuclear fusion is AMAZING. It’s set to revolutionize the way we power almost everything on the planet. And scientists are closer than ever to achieving a sustained fusion reaction. Trace tells you just how close these pioneering scientists really are.
The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom’s identity, it’s the electrons — specifically, their exact location outside the nucleus — that particularly perplex scientists. George Zaidan and Charles Morton show how to make an educated guess of where those itty-bitty freewheeling electrons might be.
What happens when you don’t sleep? And why do we need to do it anyways? Hank explains the science of sleep: the cause, the benefits, and who holds the record for going without it!
