Self-eating yeast, bagels and tiny robots: The 2016 Nobel Prizes in science

The Nobel Prizes in sciencewere announced this week, and the winning achievements arefascinatingfeaturingself-eating yeasts, tiny machinesand a concept in physics that was explained to me with a doughnut, a cinnamon bun and a pretzel.

The Nobel Prize inPhysics

You might be wondering:what do these treatshave to do with physics?

Well, the physics prizethis year went to three researchers who focus on topology. In basic terms, topology is the studyof shape. Put even more simply,it's the study of holes and whether or not an object has a hole in it.

That's where the connection to baked goods comes in.Think ofa pretzel, with two holes, a doughnut with one hole and a cinnamon bun with no holes. From a topological perspective, and the math it takes to understand its shape, the human body is basically a doughnut: a solid thing with a hole down the middle.

So, what the winners of this year'sphysicsprize DavidThouless, MichaelKosterlitz and DuncanHaldanedid was describe not only the shape of objects, but also how shape influences the movement of electrons.

Imagine you're an ant on the surface of a doughnut:you're wandering around but you don't really see that it's a doughnut. You don't see that if you're walking straight you come back to the same spot.

That's where quantum physics comes in. Unlike the ant, aquantum particle would be aware of the true shape of the doughnut. I asked Neil Turok, of the Perimeter Institutefor Theoretical Physics, to further explain:

"Aquantum particle on a doughnut would be aware of the fact that there's one long direction, one short direction, and if you go right around the doughnut you come back to where you started. It's this 'non-locality of quantum-ness' which brings about the bizarre behaviours that [the researchers] realized."

Thouless,KosterlitzandHaldane'stheoreticalresearch has been hailed as groundbreaking, and could have some very practical applicationsin the fields of electronics and quantum computing.

The Nobel Prize in Physiology or Medicine

The prize in medicine went to Dr.Yoshinori Ohsumi for his work in autophagy, which means, quite literally, to eat oneself.In cellular terms, it refers to the act of recycling elements of the cell as they age.

Autophagy was once considered a mundane part of cellular housekeeping. But research has led to a new understandingthat it plays a role in all kinds of importantphysiological processes.

Because the cellular recycling process can clear away clumps of proteins that we know can lead to neurodegenerative diseases, there's hope that better a understanding ofautophagywill lead to treatments forAlzheimer's and Parkinson's.

The Nobel Prize in Chemistry

The chemistry prize this year went to three scientists who developedwhat havebeendescribed as "the world's smallest machines".

Synthesizing this same idea in an artificially designed system has been very difficult but three chemists, Jean-Pierre Sauvage, J. Fraser Stoddart and Bernard Feringawere able to develop molecules with controllable movements.

Their research has led to an entire field of nanomachines that have the potential to transform medicine.From deliveringtargeted drug therapiesto producingartificial muscles, the sky is the limit.
