How do germs spread (and why do they make us sick)? - Yannay Khaikin and Nicole Mideo

View full lesson: ed.ted.com/less...
Germs are found on almost every surface we come in contact with, which makes it incredibly common for our bodies to be exposed to them. But why are some of these germs relatively harmless, while others can be fatal? Yannay Khaikan and Nicole Mideo explore this question by examining germs’ varying modes of transmission.

[@XsebT]

This was so simplified that I don't actually feel like I learned anything at all.

[@ltericdavis2237]

I felt like it was a a nice overview of the trade-off hypothesis, which I didn't know about. It gave a nice, understandable description of the evolutionary pressures behind virulence and transmission and possible implications.

[@bipolarwanderer]

2020? Anyone here because of COVID19

[@josemanuelmurguia8970]

i write stuff me

[@DangerousDiamond10]

im here because this is my prof lmao

[@OlivierRovelli]

I've always wondered about all of this works !

[@EmphasisOnJ]

All I learned was to stay away from germ sneezy bears in dense forests. .__.

[@EmphasisOnJ]

@reddragon-rn9ee they didn’t want my germs

[@MJake]

aaaand I'm done with dinner.

The link of this video was written in my science book

[@nycwv]

What I don't like about this immediately is that they say that you can feel the mucus land on you - that's misleading. Often you don't FEEL anything at all - and you can still get sick!

[@Shilag]

I'm done with bears as doctors!
He took one look at a collapsing girl and decided that she was a goner, no point exerting yourself. Call me speciest if you want, but I demand human doctors from now on! Or zebras.

[@vvolfgirl43]

Zebras are the best doctors. Most of the time they don't sneeze on people just so they would have to visit the doctor(them) like this greedy bear. ;)

[@ibuprofen17]

he needed to go to his vodka stash

[@EruOmokaro]

This bear is the rudest bear I've ever seen he just filinged mucus on our girl

[@vaibhavramani3807]

How do you make these videos???

[@chloethewitch]

*Corona Virus has entered the chart*

[@valiza123]

This goes to show that the doctors gave the pacient the germ (the bear is also the doctor)

[@Mrtech-sy3mk]

Yeah

[@DRiungi]

do bears sneeze in the woods?

[@AnimeshSharma1977]

aiming for the middle path :)

[@salgang606]

Done

[@SteveGottaGoFast]

can't wait to see creationsts' comments xD

[@NickDeBusk]

Germs don't evolve that's already been proven (insert ridiculous Christian "science" website link here). As I have proven that my research has been extensive and that I use words as I choose with utter disregard for their meaning. 😉

[@SteveGottaGoFast]

Nick DeBusk lol

[@just_a_saeu88]

Goldilocks & the 3 bears explaining germs ahahah :D

[@devisankhla4788]

And here we are scolded if we take an off due to a cold as we are supposed to “bear it”.

Hi 👋

[@samrocket132fitsjerols2]

Wait if I drink out of a cup when I was sick and didn't wash it... and when I wasn't sick and drank out of the cup that still wasn't wash... Would I Get Sick Again???

[@nuweirasulley6755]

where do germs and bacteria like to hide

[@williamherring2349]

That's one nasty bear, he needs to be put down.

How can encouraging viruses to become more virulent make them milder?The last points seem to contradict themselves.

[@user-de6if7ng2u]

Get away from those bears little girl they're diseased.And by the looks of the one waving it's snot at you,and the one in the lab coat,I think they're testing a new weaponized form of whatever they got.
