Hydrogen Bonding…but With Carbon | Great minds: June Sutor
Proteins, and by extension our bodies, depend on the fact that atoms are arranged, spaced, and linked to each other in specific ways. And thanks to June Sutor, we have a better understanding of how those atoms come together and interact...

TED-Ed: Pedro Brugarolas: Why do hospitals have particle accelerators?
Is there a way to detect diseases like cancer and Alzheimer's before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can...

TED: A next-gen cure for killer infections | Kary Mullis
(NOTE: This talk was given in 2009, and this field of science has developed quickly since then. Read "Criticisms & updates" below for more details.) Drug-resistant bacteria kills, even in top hospitals. But now tough infections like...

Christopher Bahl: A new type of medicine, custom-made with tiny proteins
Some common life-saving medicines, such as insulin, are made of proteins so large and fragile that they need to be injected instead of ingested as pills. But a new generation of medicine -- made from smaller, more durable proteins known...

Tal Danino: Programming bacteria to detect cancer (and maybe treat it)
Liver cancer is one of the most difficult cancers to detect, but synthetic biologist Tal Danino had a left-field thought: What if we could create a probiotic, edible bacteria that was "programmed" to find liver tumors? His insight...

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress...
