Every week, I share my notes from great TED talks. Here’s the complete list (pardon the load time, it’s a long page).
Here are 3 sets of brief notes: producer John Lloyd on what’s invisible, researcher Andrew Hessel on synthetic viruses, and biologist Robert Full on the secrets of animal movement.
What’s invisible? More than you think – John Lloyd
- we can’t see gravity. it’s the weakest and least understood of our 4 fundamental forces
- the other three are strong and weak, nuclear
- me: interestingly gravity is the only one you “feel”
- we can’t see consciousness
- Sufi masters say they’re all telepaths
- initially we thought there were 100K genes in the human genome, continually revised downward, now think only 20K genes
- rice by comparison has 38K genes (!)
- every cell in your body is replaced at some point, after 7 years all have been replaced
- we can’t see beam of light, only what it hits
- we think there are 100B galaxies but can only observe 5
- me: one of may reasons why I think there MUST be alien life
- Thomas Edison: “we don’t know one percent of one millionth about anything”
Synthetic virology | Andrew Hessel | TEDxDanubia
- the Pink Army Movement is the exact opposite of a traditional pharma company:
- not broad-use drugs, but narrow-based
- not closed, but open-source
- not for-profit, but non-profit
- an oncolytic virus is a weak virus that can’t takeover a healthy cell, but can takeover a cancerous cell (which is by definition weaker); the cancer cell then makes copies of the oncolytic virus, the cell dies, and the virus goes on to infect other cancer cells
- the cost of synthetically printing DNA has been dropping dramatically
- pharma is the opposite of Moore’s Law
- me: what a16z jokingly calls eroom’s law (‘Moore’ spelled backward, because the costs of development have risen dramatically while # of approved drugs has fallen dramatically)
Robert Full: Secrets of movement, from geckos and roaches
- animals have an array of secrets to move faster, better, up walls, etc
- gecko feet literally act like tape, they peel onto and away from surfaces, this is intermolecular forces alone (unlike ants whose feet have some of the behavioral properties but use a type of biological glue)
- other animals have tiny hooks on their feet, like cockroaches, to get more traction
- still others use their legs to act like a second/supporting foot, for more traction
